Donation after circulatory death (DCD) liver transplantation (LT) reportedly yields inferior survival and increased complication rates compared with donation after brain death (DBD). We compare 100 consecutive DCD LT using a protocol that includes thrombolytic therapy (late DCD group) to an historical DCD group (early DCD group n = 38) and a cohort of DBD LT recipients (DBD group n = 435). Late DCD LT recipients had better 1- and 3-year graft survival rates than early DCD LT recipients (92% vs. 76.3%, p = 0.03 and 91.4% vs. 73.7%, p = 0.01). Late DCD graft survival rates were comparable to those of the DBD group (92% vs. 93.3%, p = 0.24 and 91.4% vs. 88.2%, p = 0.62). Re-transplantation occurred in 18.4% versus 1% for the early and late DCD groups, respectively (p = 0.001). Patient survival was similar in all three groups. Ischemic-type biliary lesions (ITBL) occurred in 5%, 3%, and 0.2% for early DCD, late DCD, and DBD groups, respectively, but unlike in the early DCD group, in the late DCD group ITBL was endoscopically managed and resolved in each case. Using a protocol that includes a thrombolytic therapy, DCD LT yielded patient and graft survival rates comparable to DBD LT. © 2017 The American Society of Transplantation and the American Society of Transplant Surgeons.

The objective was to describe and review the use of thrombolytic therapy in a patient with an intracranial tumor and massive pulmonary embolism. This is the first reported case of a patient with a known glioblastoma multiforme and massive pulmonary embolism who was successfully treated with alteplase. Pulmonary embolism was demonstrated by a ventilation-perfusion scan and transthoracic echocardiogram with repeat studies demonstrating resolution of the thromboembolism and reperfusion of pulmonary vasculature. A review of the literature revealed that the incidence of intracranial hemorrhage with thrombolysis is <3% and compares favorably with the much higher mortality rate of 25% to >/=50% in patients with hemodynamically unstable pulmonary emboli. The benefit of thrombolysis may outweigh the risks of intracranial hemorrhage in these patients, and careful consideration for its use in these patients is warranted.

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.

Important predictors of adverse outcomes of thrombosis in children, including postthrombotic syndrome (PTS), have recently been identified. Given this knowledge and the encouraging preliminary pediatric experience with systemic thrombolysis, we sought to retrospectively analyze our institutional experience with a thrombolytic regimen versus standard anticoagulation for acute, occlusive deep venous thrombosis (DVT) of the proximal lower extremities in children in whom plasma factor VIII activity and/or D-dimer concentration were elevated at diagnosis, from within a longitudinal pediatric cohort. Nine children who underwent the thrombolytic regimen and 13 who received standard anticoagulation alone were followed from time of diagnosis with serial clinical evaluation and standardized PTS outcome assessments conducted in uniform fashion. The thrombolytic regimen was associated with a markedly decreased odds of PTS at 18 to 24 months compared with standard anticoagulation alone, which persisted after adjustment for significant covariates of age and lag time to therapy (odds ratio [OR] = 0.018, 95% confidence interval [CI] = < 0.001-0.483; P = .02). Major bleeding developed in 1 child, clinically judged as not directly related to thrombolysis for DVT. These findings suggest that the use of a thrombolysis regimen may safely and substantially reduce the risk of PTS in children with occlusive lower-extremity acute DVT, providing the basis for a future clinical trial.

To investigate the effects of the combination of extracorporeal cardiopulmonary resuscitation and thrombolytic therapy on the recovery of vital organ function after prolonged cardiac arrest. Laboratory investigation. University laboratory. Pigs. Animals underwent 30-minute untreated ventricular fibrillation cardiac arrest followed by extracorporeal cardiopulmonary resuscitation for 6 hours. Animals were allocated into two experimental groups: t-extracorporeal cardiopulmonary resuscitation (t-ECPR) group, which received streptokinase 1 million units, and control extracorporeal cardiopulmonary resuscitation (c-ECPR), which did not receive streptokinase. In both groups, the resuscitation protocol included the following physiologic targets: mean arterial pressure greater than 70 mm Hg, cerebral perfusion pressure greater than 50 mm Hg, PaO2 150 ± 50 torr (20 ± 7 kPa), PaCO2 40 ± 5 torr (5 ± 1 kPa), and core temperature 33°C ± 1°C. Defibrillation was attempted after 30 minutes of extracorporeal cardiopulmonary resuscitation. A cardiac resuscitability score was assessed on the basis of success of defibrillation, return of spontaneous heart beat, weanability from extracorporeal cardiopulmonary resuscitation, and left ventricular systolic function after weaning. The addition of thrombolytic to extracorporeal cardiopulmonary resuscitation 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 electroencephalogram 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. In a porcine model of prolonged cardiac

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.

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.

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

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.

Introduction The objective of this study was to evaluate the efficacy of ultrasound-accelerated catheter-directed thrombolytic therapy in patients with submassive pulmonary embolism. Methods Clinical records of 46 patients with submassive pulmonary embolism who underwent ultrasound-accelerated catheter-directed pulmonary thrombolysis using tissue plasminogen activator, from 2007 to 2017, were analyzed. All patients experienced clinical symptoms with computed tomography evidence of pulmonary thrombus burden. Right ventricular dysfunction was present in all patients by echocardiographic finding of right ventricle-to-left ventricle ratio > 0.9. Treatment outcome, procedural complications, right ventricular pressures, and thrombus clearance were evaluated. Follow-up evaluation included echocardiographic assessment of right ventricle-to-left ventricle ratio at one month, six months, and one year. Results Technical success was achieved in all patients ( n = 46, 100%). Our patients received an average of 18.4 ± 4.7 mg of tissue plasminogen activator using ultrasound-accelerated thrombolytic catheter with an average infusion time of 16.5± 5.4 h. Clinical success was achieved in all patients (100%). Significant reduction of mean pulmonary artery pressure occurred following the treatment, which decreased from 36 ± 8 to 21 ± 5 mmHg ( p < 0.001). There were no major bleeding complications. All-cause mortality at 30 days was 0%. No patient developed recurrent pulmonary embolism during follow-up. During the follow-up period, 43 patients (93%) showed improvement of right ventricular dysfunction based on echocardiographic assessment. The right ventricle-to-left ventricle ratio decreased from 1.32 ± 0.18 to 0.91 ± 0.13 at the time of hospital discharge ( p < 0.01). The right ventricular function remained improved at 6 months and 12 months of follow-up, as right ventricle-to-left ventricle ratio were 0.92 ± 0.14 ( p < 0.01) and 0

Treatment of prosthetic heart valve thrombosis using intravenous thrombolytics, although an acceptable alternative to surgery, is not complication free, and the literature has a dearth of data on the subject. This study analyzed the results of fibrinolytic treatment (FT) among a single-center group of patients with mechanical pulmonary valve thrombosis. Between 2000 and 2013, 23 consecutive patients with 25 episodes of pulmonary valve thrombosis received FT. The diagnosis of mechanical pulmonary valve thrombosis was established by fluoroscopy and echocardiography. Streptokinase (SK) was used in 24 cases and alteplase in 1 case. The FT was continued a second day for 14 patients (58.3%), a third day for 1 patient, and a fourth day for 1 patient. Echocardiography and fluoroscopy were performed every day until improvement of malfunction was achieved. Of the 23 patients, 19 had complete resolution of hemodynamic abnormalities after FT, 1 had partial resolution, and 2 showed no change. No patient had major complications. Five minor complications were detected, namely, fever, nausea, thrombophlebitis, epistaxi, and pain. Seven patients (30%) experienced recurrence of thrombosis, whereas four patients had surgery (biological pulmonary valve replacement) without re-thrombolytic therapy, one patient was treated with Alteplase, one patient received SK, and one patient received intense anticoagulation using heparin and warfarin. Overall, FT had a success rate of 84%. The results indicate that regardless of the time to pulmonary valve replacement and echocardiographic and fluoroscopic findings, FT was effective in most cases of mechanical pulmonary valve thrombosis. The efficacy increased with second-day thrombolytic therapy. Major complications were not common after lytic therapy for mechanical pulmonary valve thrombosis.

Deep vein thrombosis (DVT), happening in inpatients usually and especially with the postoperative population, is a serious disease characterized by an increased incidence. The venography is the golden standard to diagnose DVT. However, it involves invasive contrast agent injection and give patients physical and mental pressure. Functional nearinfrared spectroscopy (fNIRS) has been reported recently to diagnose DVT. Thrombolytic therapy activates the dissolution system with an exogenous activator that dissolves coronary thrombosis. The vena cava filter is a medical filter used for the treatment of thrombosis and the prevention of pulmonary embolism. Here we attempt to use portable NIRS for the DVT monitoring in the whole process of vena cava filter implantation and thrombolytic treatment, and contrast the patients of untreated, vena cava filter implantation and thrombolytic treatment. 19 DVT patients and 12 normal subjects were recruited. Thereinto, 7 patients have taken vena cava filter implantation, and 6 patients have taken the thrombolytic treatment. It was found that deoxyhemoglobins (Δ[Hb]) fluctuates and even increases in DVT. After vena cava filter implantation, Δ[Hb] increases first, then decreases. However, it emerges the rising trend and converge to the curves of normal subjects in thrombolytic treatment. The oxyhemoglobins (Δ[HbO2]) emerges opposite trend in most paradigms. The findings reveal the potential of fNIRS for monitoring DVT and therapeutic effect evaluation of thrombolysis and vena cava filters.

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.

Thrombolytic therapy is recommended for patients with acute ST-segment elevation myocardial infarction (STEMI) who cannot undergo primary percutaneous coronary intervention within the first 120 min. The aim of this study wasz to demonstrate the value of CHA₂DS₂-VASc and CHA₂DS₂-VASc-HS scores in predicting failed reperfusion in STEMI patients treated with thrombolytic therapy. A total of 537 consecutive patients were enrolled in the study; 139 had failed thrombolysis while the remaining 398 fulfilled the criteria for successful thrombolysis. Thrombolysis failure was defined with the lack of symptom relief, < 50% ST resolution-related electrocardiography within 90 min from initiation of the thrombolytic therapy, presence of hemodynamic or electrical instability or in-hospital mortality. CHA₂DS₂-VASc and CHA₂DS₂-VASc-HS scores, which incorporate hyperlipidemia, smoking, switches between female and male gender, were previously shown to be markers of the severity of coronary artery disease (CAD). History of hypertension, diabetes mellitus, hyperlipidemia, heart failure, smoking, and CAD were significantly common in failed reperfusion patients (for all; p < 0.05). For prediction of failed reperfusion, the cut-off value of CHA₂DS₂-VASc score was ≥ 2 with a sensitivity of 80.90% and a specificity of 41.01% (area under curve [AUC] 0.660; 95% confidence interval [CI] 0.618-0.700; p < 0.001) and the cut-off value of CHA₂DS₂-VASc-HS score was ≥ 3 with a sensitivity of 76.13% and a specificity of 67.63% (AUC 0.764; 95% CI 0.725-0.799; p < 0.001). The CHA₂DS₂-VASc-HS score was found to be statistically and significantly better than CHA₂DS₂-VASc score to predict failed reperfusion (p < 0.001). The findings suggest that the CHA₂DS₂-VASc and especially CHA₂DS₂-VASc-HS scores could be considered as predictors of risk of failed reperfusion in STEMI patients.

Introduction Proximal cervical internal carotid artery stenosis greater than 50% merits revascularization to mitigate the risk of stroke recurrence among large-vessel anterior circulation strokes undergoing mechanical thrombectomy. Carotid artery stenting necessitates the use of antiplatelets, and there is a theoretical increased risk of hemorrhagic transformation given that such patients may already have received intravenous thrombolytics and have a significant infarct burden. We investigate the outcomes of large-vessel anterior circulation stroke patients treated with intravenous thrombolytics receiving same-day carotid stenting or selective angioplasty compared to no carotid intervention. Materials and methods The study cohort was obtained from the National (Nationwide) Inpatient Sample database between 2006 and 2014, using International Statistical Classification of Diseases, ninth revision discharge diagnosis and procedure codes. A total of 11,825 patients with large-vessel anterior circulation stroke treated with intravenous thrombolytic and mechanical thrombectomy on the same day were identified. The study population was subdivided into three subgroups: no carotid intervention, same-day carotid angioplasty without carotid stenting, and same-day carotid stenting. Outcomes were assessed with respect to mortality, significant disability at discharge, hemorrhagic transformation, and requirement of percutaneous endoscopic gastronomy tube placement, prolonged mechanical ventilation, or craniotomy. Results This study found no statistically significant difference in patient outcomes in those treated with concurrent carotid stenting compared to no carotid intervention in terms of morbidity or mortality. Conclusions If indicated, it is reasonable to consider concurrent carotid stenting and/or angioplasty for large-vessel anterior circulation stroke patients treated with mechanical thrombectomy who also receive intravenous thrombolytics.

A transport-reaction model describing penetration of plasmin by diffusion and permeation into a dissolving fibrin gel was solved numerically to explore mechanisms that lead to the formation and growth of dissolution fingers through blood clots during thrombolytic therapy. Under conditions of fluid permeation driven by arterial pressures, small random spatial variations in the initial fibrin density within clots (+/-4 to 25% peak variations) were predicted by the simulation to result in dramatic dissolution fingers that grew in time. With in vitro experiments, video microscopy revealed that the shape of the proximal face of a fibrin gel, when deformed by pressure-driven permeation, led to lytic breakthrough in the center of the clot, consistent with model predictions of increased velocities in this region leading to cannulation. Computer simulation of lysis of fibrin retracted by platelets (where more permeable regions are expected in the middle of the clot due to retraction) predicted cannulation of the clot during thrombolysis. This residual, annular thrombus was predicted to lyse more slowly, because radial pressure gradients to drive inner clot permeation were quite small. In conjunction with kinetic models of systemic pharmacodynamics and plasminogen activation biochemistry, a two-dimensional transport-reaction model can facilitate the prediction of the time and causes of clot cannulation, poor reperfusion, and embolism during thrombolysis.

To retrospectively evaluate the clinical and echocardiographic criteria of thrombolytic therapy for mechanical heart valve thrombosis. Nineteen consecutive patients with 22 instances of prosthetic heart valve thrombosis (14 mitral, 2 aortic, 3 tricuspid, and 3 pulmonary) were treated with short-course thrombolytic therapy as first option of treatment in absence of contraindications. The thrombolytic therapy protocol consisted of streptokinase (1,500,000 IU in 90 minutes) (n = 18) in one (n = 7) or two (n = 11) cycles or recombinant tissue-type plasminogen activator (100 mg in 90 minutes) (n = 4). Overall success was seen in 82%, immediate complete success in 59%, and partial success in 23%. Six patients without total response to thrombolytic therapy underwent surgery, and pannus was observed in 83%. Six patients showed complications: allergy, stroke, transient ischemic attack, coronary embolism, minor bleeding, and one death. At diagnosis, 10 patients evidenced atrial thrombus by transesophageal echocardiography, 3 of whom experienced peripheral embolism during thrombolysis. Four episodes of rethrombosis were observed (16%). The survivorship was 84% with a mean follow-up of 42.6 months. A short-course of thrombolytic therapy may be considered first-line therapy for prosthetic heart valve thrombosis. The risk of peripheral embolism may be evaluated for the presence of atrial thrombus by transesophageal echocardiography at diagnosis.

We evaluated the reliability of eight clinical prediction models for symptomatic intracerebral hemorrhage (sICH) and long-term functional outcome in stroke patients treated with thrombolytics according to clinical practice. In a cohort of 169 patients, 60 patients (35.5%) received IV rtPA according to the European license criteria. The remaining patients received off-label IV rtPA and/or were treated with intra-arterial thrombolysis. We used receiver operator characteristic curves to analyze the discriminative capacity of the MSS score, the HAT score, the SITS SICH score, the SEDAN score and the GRASPS score for sICH according to the NINDS and the ECASSII criteria. Similarly, the discriminative capacity of the s-TPI, the iScore and the DRAGON score were assessed for the modified Rankin Scale (mRS) score at 3 months poststroke. An area under the curve (c-statistic) >0.8 was considered to reflect good discriminative capacity. The reliability of the best performing prediction model was further examined with calibration curves. Separate analyses were performed for patients meeting the European license criteria for IV rtPA and patients outside these criteria. For prediction of sICH c-statistics were 0.66-0.86 and the MMS yielded the best results. For functional outcome c-statistics ranged from 0.72 to 0.86 with s-TPI as best performer. The s-TPI had the lowest absolute error on the calibration curve for predicting excellent outcome (mRS 0-1) and catastrophic outcome (mRS 5-6). All eight clinical models for outcome prediction after thrombolysis for acute ischemic stroke showed fair predictive value in patients treated according daily practice. The s-TPI had the best discriminatory ability and was well calibrated in our study population. Copyright © 2014 Elsevier B.V. All rights reserved.

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

2015-04-01

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.

To determine the safety and effectiveness of vascular closure devices in prevention of access site complications in acute stroke patient receiving intravenous (IV) and/or intra-arterial (IA) IV tissue plasminogen activator (tPA). All patients with acute stroke onset treated with IV and/or IA tPA closed with vascular closure device and adult age (>18 years) were identified from an academic tertiary medical center and a teaching community hospital stroke database for 9 years (from March 2005 to June 2014). A total of 69 patients were included in the study. The mean age was 68.86±16.70 years and 49.2% female. All accesses were under fluoroscopic guidance into the right common femoral artery. We observed a 5.8% complication rate in patients receiving IV and/or IA tPA closed with vascular closure device. Access site complications included 3 cases of hematoma and 1 case of residual oozing. One patient required transfusion due to access site hematoma. Three patients were on aspirin and heparin and 1 was on no prior anticoagulation. Vascular closure device access site hemorrhagic complication rate in those receiving IV and/or IA tPA is low and similar to reported rates in those not receiving thrombolytic therapy. Vascular closure device use in patients receiving thrombolytic therapy is safe and effectively achieves hemostasis. Copyright © 2017 Elsevier B.V. All rights reserved.

Echogenic liposomes loaded with the thrombolytic recombinant tissue-type plasminogen activator (rt-PA) are under development for the treatment of ischemic stroke. These agents are designed to co-encapsulate cavitation nuclei to promote bubble activity in response to ultrasound exposure, and to enable localized delivery of thrombolytic. Stable cavitation improves the efficacy of the thrombolytic through enhanced fluid mixing. Echogenic liposomes that encapsulate air-filled microbubbles nucleate scant stable cavitation activity in response to 120 kHz intermittent ultrasound exposure, and have demonstrated thrombolytic efficacy equivalent to rt-PA alone. It was hypothesized that encapsulating octafluoropropane (OFP) gas within rt-PA-loaded liposomes instead of air will enhance ultrasound-mediated stable cavitation activity and increase thrombolytic efficacy compared to previous studies. The thrombolytic efficacy and cavitation activity nucleated from liposomes that encapsulate OFP microbubbles and rt-PA (OFP t-ELIP) was evaluated in vitro. Human whole blood clots were exposed to human fresh-frozen plasma alone, rt-PA (0, 0.32, 1.58, and 3.15 µg ml-1), or OFP t-ELIP at equivalent enzymatic activity, with and without exposure to intermittent ultrasound. Further, numerical simulations were performed to gain insight into the mechanisms of cavitation nucleation. Sustained ultraharmonic activity was nucleated from OFP t-ELIP when exposed to ultrasound. Furthermore, the thrombolytic efficacy was enhanced compared to rt-PA alone at concentrations of 1.58 µg ml-1 and 3.15 µg ml-1 (p  <  0.05). These results indicate that OFP t-ELIP can nucleate sustained stable cavitation activity and enhance the efficacy of thrombolysis.

Treatment rates with intravenous tissue plasminogen activator vary by region, which can be partially explained by organizational models of stroke care. A recent study demonstrated that prehospital factors determine a higher thrombolysis rate in a centralized vs. decentralized model in the north of the Netherlands. To investigate prehospital factors that may explain variation in thrombolytic therapy between a centralized and a decentralized model. A consecutive case observational study was conducted in the north of the Netherlands comparing patients arriving within 4·5 h in a centralized vs. decentralized stroke care model. Factors investigated were transportation mode, prehospital diagnostic accuracy, and preferential referral of thrombolysis candidates. Potential confounders were adjusted using logistic regression analysis. A total of 172 and 299 arriving within 4·5 h were enrolled in centralized and decentralized settings, respectively. The rate of transportation by emergency medical services was greater in the centralized model (adjusted odds ratio 3·11; 95% confidence interval, 1·59-6·06). Also, more misdiagnoses of stroke occurred in the central model (P = 0·05). In postal code areas with and without potential preferential referral of thrombolysis candidates due to overlapping catchment areas, the odds of hospital arrival within 4·5 h in the central vs. decentral model were 2·15 (95% confidence interval, 1·39-3·32) and 1·44 (95% confidence interval, 1·04-2·00), respectively. These results suggest that the larger proportion of patients arriving within 4·5 h in the centralized model might be related to a lower threshold to use emergency services to transport stroke patients and partly to preferential referral of thrombolysis candidates. © 2013 The Authors.

Current findings suggest that the efficacy of thrombolytic therapy may be limited by the availability of active forms of plasminogen at the thrombus site. The purpose of this study was to determine if the systemic administration of 0.5 mg kg-1 glu-plasminogen (glu-plg) or 0.5 mg kg-1 lys-plasminogen (lys-plg) could safely increase the efficacy of a single intravenous bolus injection of 50,000 U kg-1 prourokinase (proUK) in a dog model of arterial thrombosis. Thrombolysis was measured by monitoring the continuous decrement of 125I-gamma emissions from a radiolabeled thrombus. Reflow was evaluated by direct visual examination. Forty dogs (mean wt 10.3 +/- 2 kg) were randomly sorted into 4 groups of 10 each. The dogs in each group were given either saline plus saline, saline plus proUK, glu-plg plus proUK, or lys-plg plus proUK 60 minutes after formation of an occlusive arterial thrombus. Ninety minutes after drug administration the dogs receiving saline plus proUK, glu-plg plus proUK, and the lys-plg plus proUK showed greater thrombolysis (41%, 43%, and 66%, respectively) than the control (saline plus saline) group (15%, P less than 0.01). The lys-plg plus proUK treatment caused greater lysis than the saline plus proUK or the glu-plg plus proUK treatment (P less than 0.05). All of the dogs (10/10) receiving lys-plg plus proUK had patent vessels at the end of the 90 minute monitoring period, whereas only 4/10 and 5/10 vessels were patent in the saline plus proUK and glu-plg plus proUK groups, respectively. None of the dogs in the saline plus saline group had patent vessels. No significant changes were observed in the various coagulation parameters tested for any of the 4 treatment groups. The results show that lys-plg can safely increase the thrombolytic efficacy of proUK.

We studied the antithrombotic and thrombolytic effects of Trombovazim, a highly-purified proteolytic enzyme preparation obtained by immobilization of bacterial proteinases (Bacillus) on polyethylene oxide with a molecular weight of 1.5 kDa. Blood absorption of the preparation was evaluated after intragastric administration. In vitro experiments showed that Trombovazim produces anticoagulant and thrombolytic effects, which manifested in inhibition of fibrin clot formation and acceleration of its lysis. Drug concentration in the blood was elevated from the 4th to the 7th hour after intragastric administration of Trombovazim in a dose of 2250 U/kg, being maximum by the 5th hour (0.044+/-0.011 U/ml). Course treatment with Trombovazim (1000 U intragastrically, twice daily for 3 days) had a thrombolytic effect on rats with experimental intravascular thrombosis. This effect was manifested in a decrease in thrombus weight and increase in the percent of rats with recanalization of the occluded carotid artery.

Nattokinase is a new fibrinolytic enzyme which cleaves directly cross-linked fibrin in vitro. In this study, we investigated the thrombolytic effect of nattokinase on a thrombus in the common carotid artery of rat in which the endothelial cells of the vessel wall were injured by acetic acid. When a section of occluded vessel was stained for CD61 antigen by immunofluorescence utilizing a monoclonal antibody, the antigen was localized around the surface of the occluded blood vessels. This result suggests that the occlusive thrombosis was caused by platelet aggregation. In addition, thrombolysis with urokinase (UK; 50000 IU/kg, i.v.) or tissue plasminogen activator (tPA; 13300 IU/kg, i.v.) in our model was observed to restore the blood flow over a 60 min monitoring period. The results indicate that our chemically induced model is useful for screening and evaluating a thrombolytic agent. We evaluated the thrombolytic activity of nattokinase using this model and compared it with fibrino(geno)lytic enzyme, plasmin or elastase. On a molar basis, the recovery of the arterial blood flow with nattokinase, plasmin and elastase were 62.0 +/- 5.3%, 15.8 +/- 0.7% and 0%, respectively. The results indicate that the thrombolytic activity of nattokinase is stronger than that of plasmin or elastase in vivo.

Disability-adjusted life year (DALY) metric reflects years of healthy life lost because of living with disability and years of life lost because of premature mortality. Widely used in epidemiological analyses, DALY has not been applied to acute stroke trials. From previous studies, we derived, for each modified Rankin Scale level, disability weights, disability-linked mortality hazard ratios, and age-specific life expectancies. We then analyzed patient level data from the 2 publicly available National Institute of Neurological Disorders and Stroke (NINDS) recombinant tissue plasminogen activator trials. For each subject, we abstracted age, treatment assignment, and 3-month modified Rankin Scale outcome and calculated the DALYs lost resulting from the qualifying stroke. The disability-linked hazard ratios for premature annual mortality for a modified Rankin Scale score of 0 to 5 were 1.53, 1.52, 2.17, 3.18, 4.55, and 6.55, respectively. In the NINDS recombinant tissue plasminogen activator trials, DALYs (mean+/-SE) lost as a result of the qualifying stroke were substantially less with recombinant tissue plasminogen activator than with placebo (4.64+/-0.17 versus 5.91+/-0.21; P<0.0001), a finding that remained robust after adjustment for baseline prognostic factors. When DALYs gained were apportioned to the 29% of patients experiencing any benefit from lytic therapy, each patient gained an average of 4.4 DALYs. DALY analysis showed greater power than dichotomized modified Rankin Scale analysis in discriminating treatment effects overall and in patients >or=70 years of age. For patients who benefit from treatment, <3-hour thrombolytic therapy adds the equivalent of 4.4 years of healthy life, free of disability. The DALY metric provides a continuous scale that increases statistical power, is intuitively understandable, and is applicable to a wide range of conditions and treatments.

Background 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. Methods 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. Results 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. Conclusions 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.

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. The aim of this study was to enhance the production of NK from Pseudomonas aeruginosa CMSS by media optimization and strain improvement. 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. 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 dodecyl sulfate polyacrylamide gel

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

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.

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

Intravenous recombinant tissue plasminogen activator (tPA) at a dose of 0.9 mg/kg body weight is associated with a high hemorrhagic transformation (HT) rate. Low-dose tPA (0.6 mg/kg) may have a lower hemorrhage rate but the mortality and disability rates at 90 days cannot be confirmed as non-inferior to standard-dose tPA. Whether the doses 0.7 and 0.8 mg/kg have better efficacy and safety needs further investigation. Therefore, this study is to compare the efficacy and safety of each dose of tPA (0.6, 0.7, 0.8, and 0.9 mg/kg body weight) and to investigate the factors affecting early neurological improvement (ENI) and early neurological deterioration (END). For this observational study, data were obtained from 274 patients who received tPA thrombolytic therapy in Chia-Yi Christian Hospital stroke unit. The tPA dose was given at the discretion of each physician. The definition of ENI was a >8 point improvement (compared with baseline) at 24 h following thrombolytic therapy or an improvement in the National Institutes of Health Stroke Score (NIHSS) to 0 or 1 toward the end of tPA infusion. The definition of END was a >4 point increase in NIHSS (compared with baseline) within 24 h of tPA infusion. The primary objective was to investigate whether 0.7 and 0.8 mg/kg of tPA have higher ENI rate, lower END rate, and better outcome at 6 months. Poor outcome was defined as having a modified Rankin Scale of 3 to 6 (range, 0 [no symptoms] to 6 [death]). The secondary objective was to investigate whether low-dose tPA has a lower risk of intracerebral HT than that with standard-dose tPA. We also investigated the factors affecting ENI, END, HT, and 6-month outcome. A total of 274 patients were included during the study period, of whom 260 were followed up for >6 months. There was a trend for the HT rate to increase as the dose increased ( P =0.02). The symptomatic HT rate was not significantly different among the low-dose and standard-dose groups. The ENI and END ( P =0.52) were

Patients With Brain Tumors: Who Receives Postacute Occupational Therapy Services?

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.

The concept of equivalence and its application to the assessment of thrombolytic effects.

PubMed

Hampton, J R

1997-12-01

Very large clinical trials have become the norm in the evaluation of thrombolytic agents, and these 'megatrials' are administratively complex and expensive. It remains to be seen whether new thrombolytics will lead to further large reductions in fatality from an acute myocardial infarction, but new agents may well have advantages in areas such as safety and ease of administration, in addition to other clinical benefits (i.e. fewer cases of cardiac shock, heart failure and atrial fibrillation). The problem is how to introduce such new agents without a megatrial for each one. Endpoints other than fatality have some advantages and, in thrombolysis, angiographic studies are a necessary step in the development of new agents. However, such studies may not always correlate precisely with the results of mortality endpoint studies. Measurements of the resolution of ST segment elevation in myocardial infarction seem to provide a very useful method of assessing thrombolysis, but although such a technique can be applied to large numbers of patients, it cannot totally replace mortality endpoint trials. The 'equivalence' of two treatments is a clinical, not a statistical, concept, although statistical principles that allow equivalence to be investigated with medium-sized trials should be applied. Demonstrating equivalence in outcome between the new thrombolytic reteplase and streptokinase was the aim of the INJECT study.

Current smokers who are prescribed home oxygen may not benefit from the therapy. In addition to being an obvious fire hazard, there is some evidence that the physiological mechanisms by which home oxygen is believed to operate are inhibited by smoking. Although their effectiveness is yet to be demonstrated, electronic cigarettes (e-cigarettes) are often regarded as an aid to smoking cessation. However, several burn accidents in e-cigarette smokers receiving home oxygen therapy have also been reported, leading Health Canada to release a warning of fire risk to oxygen therapy patients from e-cigarettes. It is the authors' position that patients receiving oxygen should definitely not use e-cigarettes. The authors provide suggestions for addressing the delicate issue of home oxygen therapy in current cigarette and⁄or e-cigarette smokers.

Listeriosis in patients receiving biologic therapies.

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.

Nattokinase is a serine protease produced by Bacillus subtilis during the fermentation of the soybean product natto. The fibrinolytic activity and thrombolytic effects of nattokinase have been observed in vitro, but the effect in vivo has still to be researched. The objective of this study was to demonstrate the activity of nattokinase in vivo. To establish a rat model of thrombosis, κ-carrageenan was injected subcutaneously into the toes of Sprague-Dawley (SD) rats. Histological examination confirmed thrombosis. The rats were then treated with varying doses of nattokinase and the resulting thrombolysis was histologically assessed. ELISA was used to determine the levels of the fibrin/fibrinogen degradation products (FDPs) and D-dimer, which are sensitive indices of fibrinolytic activity. Vermis kinase, a known thrombolytic agent, was used as a positive control. Biopsy results revealed partial thrombolysis in the tail vessels of the rats treated with nattokinase or vermis kinase. FDP and D-dimer levels were higher in rats treated with high-dose nattokinase than in those treated with saline. No difference in FDP or D-dimer levels was observed between rats treated with high-dose nattokinase and those treated with vermis kinase. Both the histological and physiological evidence from this study indicate that nattokinase exerts thrombolytic effects in vivo.

Background It is widely believed that ST-elevated myocardial infarction (STEMI) generally occurs at the site of mild to moderate coronary stenosis. The aim of this study was to determine the degree of stenosis of infarct-related artery (IRA) in STEMI patients who underwent coronary angiography (CAG) after successful reperfusion with thrombolytic therapy (TT). Methods A total of 463 consecutive patients between January 2008 and December 2013 with acute STEMI treated with TT were evaluated retrospectively. The patients in whom reperfusion failed (n = 120), death occurred before CAG (n = 12), IRA cannot be determined (n = 10), and CAG was not performed in index hospitalization (n = 54) were excluded from the study. To determine the severity of stenosis of IRA, two experienced cardiologists who were unaware of each other used quantitative CAG analysis. Significant stenosis was defined as a ≥ 50% stenosis in the coronary artery lumen. A total of 267 patients who were successfully reperfused with TT and in whom CAG was performed during hospitalization with median 8 (1 - 17) days after myocardial infarction were included in the study. Results The mean age of patients was 55.7 ± 10.8 years (85.5% male). Most of the patients had a significant stenosis in IRA ( ≥ 50%, n = 236, group 1) after successful TT; whereas only 11.6% had stenosis < 50% (n = 31, group 2). In addition, majority of the patients had ≥ 70.4% (n = 188, 70.4%) stenosis in IRA. Average of stenosis in IRA was 74±16%. Conclusions In contrast to the general opinion, we detected that majority of STEMI patients had a significant stenosis in IRA. PMID:29479380

It has been unclear whether thrombolytic-related asymptomatic hemorrhagic transformation (AHT) affects the clinical outcome. To answer this question, we examined whether thrombolytic-related AHT affect short-term and long-term clinical outcome. All data were collected from the Thrombolysis Implementation and Monitor of Acute Ischemic Stroke in China (TIMS-China) registry. The patients were diagnosed as having AHT group and non- hemorrhagic transformation (HT) group based on clinical and imaging data. The patients with symptomatic hemorrhagic transformation were excluded from this study. Thrombolytic-related AHT was defined according to European-Australasian Acute Stroke Study (ECASS) II criteria. 90-day functional outcome, 7-day National Institutes of Health Stroke Scale (NIHSS) score, 7-day and 90-day mortalities were compared between two groups. Logistic regression analysis was used to evaluate the effects of AHT on a short-term and long-term clinical outcome. 904 of all 1440 patients in TIMS-China registry were enrolled. 89 (9.6%) patients presented with AHT after thrombolysis within 24-36 h. These patients with AHT were more likely to be elder age, cardioembolic subtype, and to have higher National Institutes of Health Stroke Scale score before thrombolysis than patients without AHT. No significant difference was found on the odds of 7-day (95% CI:0.692 (0.218-2.195), (P = 0.532) or 90-day mortalities (95% CI:0.548 (0.237-1.268), P = 0.160) and modified Rankin Score(0-1) at 90-day (95% CI:0.798 (0.460-1.386), P = 0.423) or modified Rankin Score(0-2) at 90-day (95% CI:0.732 (0.429-1.253), P = 0.116) or modified Rankin Score(5-6) at 90-day (95% CI:0.375 (0.169-1.830), P = 0.116) between two groups. Thrombolytic-related AHT does not deteriorate short-term and long-term clinical outcome.

To assess the prevalence of dyslipidemia and lipodystrophy in Indian children receiving non-nucleoside reverse transcriptase inhibitor (NNRTI) based highly active antiretroviral therapy (HAART) and to determine the associated risk factors for the same. The present cross-sectional study was conducted at a Pediatric Clinic of a tertiary care teaching center in India, from May 2011 through December 2012. HIV infected children aged 5-15 y were enrolled if they did not have any severe disease or hospital admission within last 3 mo or receive any medications known to affect the lipid profile. Eighty-one children were on highly active antiretroviral therapy (HAART) for at least 6 mo and 16 were receiving no antiretroviral therapy (ART). Participants' sociodemographic, nutritional, clinical, and laboratory data were recorded in addition to anthropometry and evidence of lipodystrophy. Fasting lipid profile, apolipoprotein A1 and B levels were done for all the children. Among the children on highly active antiretroviral therapy (HAART), 38.3 % had dyslipidemia and 80.2 % had lipodystrophy, while 25 % antiretroviral therapy (ART) naïve HIV infected children had dyslipidemia. No clinically significant risk factors could be identified that increased the risk of dyslipidemia or lipodystrophy in children on highly active antiretroviral therapy (HAART). There is a high prevalence of dyslipidemia and lipodystrophy in Indian children with HIV infection with an imminent need to establish facilities for testing and treatment of these children for metabolic abnormalities.

Cannabis can augment thrombolytic properties of rtPA: Intracranial hemorrhage in a heavy cannabis user.

Cannabis is one of the most commonly used illicit drugs in the United States and is considered to have several adverse health effects. There is evidence suggesting that its recreational use is associated with both increased cardio- and cerebrovascular events. Recently, multiple cases of ischemic and hemorrhagic strokes associated with cannabis use were reported in the literature (Goyal et al., 2017). It has been suggested that cannabis can affect cerebral auto-regulation and vascular tone leading to vasoconstriction and acute ischemic stroke. However, hemorrhagic strokes, which are often seen with sympathomimetic illicit drugs (e.g. cocaine and amphetamines), have rarely been reported due to cannabis. Many cellular mechanisms within non-ischemic tissue post stroke may be augmented by heavy cannabis use. Here, we describe a rapid development of hemorrhage following thrombolytic therapy in a patient with heavy cannabis use with an ischemic stroke. Copyright © 2017 Elsevier Inc. All rights reserved.

Objective To investigate the antioxidant, antimicrobial, cytotoxic and thrombolytic property of the fruits and leaves of Spondias dulcis (S. dulcis). Methods Methanolic extracts of fruits and leaves of S. dulcis were partitioned with chloroform and dichloromethane. The antioxidant potential of the crude extract and partitioned fractions were evaluated in terms of total phenolic content, total flavonoid content, DPPH radical scavenging potential, reducing potential and total antioxidant capacity by specific standard procedures. The antimicrobial activity was evaluated using disc diffusion method. The cytotoxicity was evaluated by using brine shrimp lethality bioassay and compared with vincristine sulfate. The thrombolytic activity was compared with streptokinase. Results The methanolic fruit extract exhibited the highest phenolic content, flavonoid content and antioxidant capacity, among the other extracts, with the highest DPPH radical scavenging activity at a concentration of 10 µg/mL (IC50: 1.91 µg/mL) and maximum reducing power at a concentration of 100 µg/mL (EC50: 3.58 µg/mL). Though all extract showed moderate antimicrobial activity against the bacterial strains, weak or no activity against fungus. The range of LC50 value of all extracts was 1.335-14.057 µg/mL which was far lower than the cut off index for cytotoxicity. All extracts exhibited statistically significant (P<0.001) thrombolytic activity. Conclusions Our study suggested that S. dulcis exhibits antimicrobial activities against a wide variety of strains while it possesses significant antioxidant, cytotoxic and thrombolytic activity.

PurposeTo assess the feasibility, effectiveness, and safety of catheter-directed thrombolysis and aspiration thrombectomy therapy by combined route of superior mesenteric vein and artery (SMV+SMA) for acute superior mesenteric venous thrombosis (ASMVT).MethodsThis retrospective study reviewed eight ASMVT patients with transcatheter direct thrombolysis and aspiration thrombectomy therapy via SMV and indirect thrombolysis via SMA during a period of 14 months. The demographics, etiology, risk factors, therapeutic effect, complications, mortality, and follow-up of the study population were assessed. Anatomic and imaging classification of location and extent of thrombus at diagnosis and degree of thrombus lysis were described.ResultsTechnical success was achieved with substantial improvement inmore » symptoms and thrombus resolution after thrombolytic therapy in all patients. The local urokinase infusion by SMA and SMV was performed for 5–7 (6.13 ± 0.83) and 7–15 (12 ± 2.51) days. Anticoagulation was performed catheter-directed and then orally throughout hospitalization and after discharge. Four patients required delayed localized bowel resection after thrombolytic therapy with no death. Thrombolytic therapy was not interrupted despite minor bleeding at the puncture site in two patients and sepsis in another two postoperatively. Nearly complete removal of thrombus was demonstrated by contrast-enhanced CT scan and portography before discharge. Patients were discharged in 10–27 (19.25 ± 4.89) days after admission. No recurrence developed during the follow-up of 10–13 (12.13 ± 0.99) months.ConclusionsCatheter-directed thrombolytic and aspiration therapy via SMV+SMA is beneficial for ASMVT in avoiding patient death, efficient resolving thrombus, rapid improving symptoms, reversing extensive intestinal ischemia, averting bowel resection, or localizing infarcted bowel segment and preventing short bowel syndrome.« less

Background and Purpose— Computed tomographic angiography and magnetic resonance angiography are used increasingly to assess arterial patency in patients with ischemic stroke. We determined which baseline angiography features predict response to intravenous thrombolytics in ischemic stroke using randomized controlled trial data. Methods— We analyzed angiograms from the IST-3 (Third International Stroke Trial), an international, multicenter, prospective, randomized controlled trial of intravenous alteplase. Readers, masked to clinical, treatment, and outcome data, assessed prerandomization computed tomographic angiography and magnetic resonance angiography for presence, extent, location, and completeness of obstruction and collaterals. We compared angiography findings to 6-month functional outcome (Oxford Handicap Scale) and tested for interactions with alteplase, using ordinal regression in adjusted analyses. We also meta-analyzed all available angiography data from other randomized controlled trials of intravenous thrombolytics. Results— In IST-3, 300 patients had prerandomization angiography (computed tomographic angiography=271 and magnetic resonance angiography=29). On multivariable analysis, more extensive angiographic obstruction and poor collaterals independently predicted poor outcome (P<0.01). We identified no significant interaction between angiography findings and alteplase effect on Oxford Handicap Scale (P≥0.075) in IST-3. In meta-analysis (5 trials of alteplase or desmoteplase, including IST-3, n=591), there was a significantly increased benefit of thrombolytics on outcome (odds ratio>1 indicates benefit) in patients with (odds ratio, 2.07; 95% confidence interval, 1.18–3.64; P=0.011) versus without (odds ratio, 0.88; 95% confidence interval, 0.58–1.35; P=0.566) arterial obstruction (P for interaction 0.017).

Herpes simplex virus encephalitis (HSE) is a significant cause of morbidity and mortality. Neurologic sequelae are common even after early initiation of acyclovir treatment. The host immune response during HSE can also lead to brain damage. There are an increasing number of reports favoring steroid use in HSE. We aimed to compare the prognosis of children with HSE with and without steroid therapy. We retrospectively screened our hospital archive from 2009 to 2014 for patients diagnosed with HSE with a positive result for herpes simplex virus polymerase chain reaction in cerebrospinal fluid. Patients ≥1 month and ≤18 years at diagnosis were included in the study. Clinical outcomes in terms of cognitive function, motor function, electroencephalographic findings, seizure frequency, and radiologic findings were compared in patients who received adjuvant steroid therapy with those who did not. Six patients (1 boy, 5 girls; aged 4 months to 10 years) were included. Overall symptom duration before hospital admission was ≤5days. Patients received acyclovir treatment for 21-28days. Three received steroid therapy early during the disease and three patients did not. No adverse effects related to steroids were observed. Follow-up duration was 6 months to 5 years. All patients had radiologic sequelae of encephalitis. Cognition, motor function, and seizure control were better in patients who received steroid therapy. Adjuvant steroid therapy seems to be effective in decreasing morbidity in children with HSE but the radiologic sequelae were the same in both groups. Copyright © 2016 Elsevier B.V.

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.

Several anticoagulants, anti-platelet and thrombolytic medications are used for the treatment of thrombotic disorders. Anti-coagulants and anti-platelet agents prevent the formation of blood clots but do not dissolve existing clots, whereas thrombolytic agents are able to dissolve a clot but emboli can form even after successful treatment. Thus, none of them provide a permanent and complete solution. In this regard a single molecule that could both dissolve the clot and prevent the formation of new clots would be useful in the treatment of thrombotic diseases. Crinumin, a stable and active (in many adverse conditions) serine protease, shows plasmin-like fibrinolytic activity and inhibits platelet aggregation and P-selectin exposure, as established by photography, phase contrast microscopy, whole blood optical Lumi-aggregometry and flow cytometry. Crinumin could be an efficient and inexpensive therapeutic agent for the treatment and prevention of thromboembolic diseases. Copyright © 2011 Elsevier Inc. All rights reserved.

[The percutaneous action of a heparin-allantoin-dexpanthenol combination in a specific ointment base. Thrombolytic action on the rabbit ear].

Experimentally induced thrombi of ear veins in albino rabbits have been treated locally with heparin-containing ointments in presence or absence of allantoin and dexpanthenol, the heparin concentration varying. While the ointments, containing heparin only, induce no or only minor thrombolytic activity, the combination ointments Hepathrombin Adenylchemie containing heparin, allantoin and dexpanthenol show significant thrombolytic activity. This effect is dependent upon the heparin concentration, yet, heparin doses above 50 000 IU per 100 g of ointment do not enhance the thrombolysis furthermore. Further, the studies show that the effective components of Hepathrombin do penetrate into and through the skin, allantoin and dexpanthenol being important components of the ointment probably supporting the transdermal penetration of heparin. The studies also demonstrate the only local thrombolytic effect of the Hepathrombin ointments because the thrombus of the right ear, always treated with ointment base only, did not show any change in length as contrasted to that of the left ear of the same animal treated with the Hepathrombin ointments. Mechanisms of the locally by Hepathrombin/heparin induced thrombolysis will be discussed.

Background/Purpose Identifying modifiable tPA treatment delays may improve stroke outcomes. We hypothesized that pre-thrombolytic anti-hypertensive treatment (AHT) may prolong door-to-treatment time (DTT). Methods Analysis of consecutive tPA-treated patients at 24 randomly selected community hospitals in the INSTINCT trial between 2007-2010. DTTs among stroke patients who received pre-thrombolytic AHT were compared to those that did not receive pre-thrombolytic AHT. We then calculated a propensity score for the probability of receiving pre-thrombolytic AHT using logistic regression with demographics, stroke risk factors, home medications, stroke severity (NIHSS), onset-to-door time, admission glucose, pretreatment blood pressure, EMS transport and location at time of stroke as independent variables. A paired t-test was performed to compare the DTTs between the propensity matched groups. Results Of 534 tPA treated stroke patients analyzed, 95 received pre-thrombolytic AHT. In the unmatched cohort, patients who received pre-thrombolytic AHT had a longer DTT (mean increase 9 minutes; 95% confidence interval (CI) 2-16 minutes) than patients who did not. After propensity matching, patients who received pre-thrombolytic AHT had a longer DTT (mean increase 10.4 minutes, 95% CI 1.9 - 18.8) than patients who did not receive pre-thrombolytic AHT. Conclusion Pre-thrombolytic AHT is associated with modest delays in DTT. This represents a potential target for quality improvement initiatives. Further research evaluating optimum pre-thrombolytic hypertension management is warranted. PMID:23033348

Purpose: Multiple studies have shown survival benefits in patients with cancer treated with radiation therapy, but access to treatment facilities has been found to limit its use. This study was undertaken to examine access issues in Iowa and determine a methodology for conducting a similar national analysis. Patients and Methods: All Iowa residents who received radiation therapy regardless of where they were diagnosed or treated were identified through the Iowa Cancer Registry (ICR). Radiation oncologists were identified through the Iowa Physician Information System (IPIS). Radiation facilities were identified through IPIS and classified using the Commission on Cancer accreditation standard. Results: Between 2004 and 2010, 113,885 invasive cancers in 106,603 patients, 28.5% of whom received radiation treatment, were entered in ICR. Mean and median travel times were 25.8 and 20.1 minutes, respectively, to the nearest facility but 42.4 and 29.1 minutes, respectively, to the patient's chosen treatment facility. Multivariable analysis predicting travel time showed significant relationships for disease site, age, residence location, and facility category. Residents of small and isolated rural towns traveled nearly 3× longer than urban residents to receive radiation therapy, as did patients using certain categories of facilities. Conclusion: Half of Iowa patients could reach their nearest facility in 20 minutes, but instead, they traveled 30 minutes on average to receive treatment. The findings identified certain groups of patients with cancer who chose more distant facilities. However, other groups of patients with cancer, namely those residing in rural areas, had less choice, and some had to travel considerably farther to radiation facilities than urban patients.

The clinical manifestation of asthma in children can interfere with their daily activities. Music therapy may become one of the alternative approaches to making children feel comfortable during inhalation therapy. The aim of the study was to identify the effects of music therapy on the physiological response of asthmatic preschool and school-age children receiving inhalation therapy. This study used a quasi-experimental, nonequivalent control group with a pre-test-post-test design. The 44 respondents consisted of preschool and school-age children assigned to intervention and control groups. The results showed a significant difference in average oxygen saturation, heart rate, and respiratory rate between the control and intervention groups before and after intervention (p < α; α = .05). Music therapy can be used as a nursing intervention to improve the physiological response of children with breathing problems.

Background Thrombosis is a complication of prosthetic valves on oral anticoagulants which is associated with significant morbidity and mortality. A re-operation carries a substantial risk, with mortality rate from 10% to 15% in selected series, which may be 2- or 3-folds higher in critically ill patients. This study conducted in a tertiary care cardiology unit aimed to evaluate the effectiveness and safety of thrombolytic therapy in stuck mitral bileaflet heart valves. Methods As a prospective observational study, clinical symptoms and fluoroscopy were the mainstay in diagnosis of stuck mitral valve. Gradient across the valve by transthoracic echocardiography was used to monitor the therapy every 6 h. Fall of mean gradient more than 50% was considered as successful thrombolysis. And final results were again checked by fluoroscopy with documentation of improved leaflet movement. Results Totally we studied 34 patients. Patients receiving thrombolytic therapy with streptokinase achieved an overall 91.2% freedom from a repeat operation or major complications, a large subcutaneous hematoma occurred in one ( 2.9%), reoperation required in two due to failure of treatment (5.9%), allergic reaction in one (2.9%), one patient developed transient neurologic dysfunction (2.9%) and one patient died during therapy due to refractory cardiogenic shock(2.9%). All patients including those with delayed presentation (> 14 days) and hemodynamically unstable patients had good results similar to those who presented within 14 days and hemodynamically stable. Mortality was higher in unstable patients and reoperation was higher with delayed presentation. Conclusions Thrombolysis with streptokinase is highly successful and safe therapy in hemodynamically stable as well as unstable patients, or those with early or delayed presentation with stuck bileaflet mitral valves, especially in centers where round the clock cardiothoracic surgery backup is not available.

Systemic thrombolysis was introduced as the sole prehospital treatment option in patients with cardiac arrest in the setting of acute myocardial ischemia or pulmonary embolism; however, it remains the subject of discussion. A total of 194 patients with sudden prehospital cardiac arrest were included in this retrospective case control study. Of these patients, 96 in whom circulatory arrest due to cardiac disease (pulmonary artery embolism or myocardial ischemia) was suspected underwent thrombolytic treatment and were compared to the remaining 98 patients that did not undergo thrombolytic therapy. In addition to the circumstances of circulatory arrest, the course and success of resuscitation, as well as in-hospital course (including bleeding complications), overall survival and neurological outcomes were compared. There were no significant differences between patients with or without thrombolysis in terms of the circumstances of cardiac arrest. Patients that received thrombolytic treatment were significantly younger and were more frequently treated with anticoagulants, platelet aggregation inhibitors and amiodarone. They also received higher doses of epinephrine and arrived at hospital under ongoing resuscitation significantly more frequently. A trend toward more prehospital return of spontaneous circulation (ROSC) following thrombolytic treatment was seen in the entire cohort. However, patients pre-treated with acetylsalicylic acid and heparin did not show better prehospital ROSC rates as a result of additional thrombolytic therapy. Significant differences in terms of bleeding complications or the need for blood transfusion could not be seen due to the small number of patients. The indication for systemic thrombolysis in the context of prehospital resuscitation should remain restricted to patients with clear symptoms of acute pulmonary embolism or recurrent episodes of ventricular fibrillation in the setting of acute myocardial infarction.

The human tissue-type plasminogen activator (tPA) is a key kinase of fibrinolysis that plays an important role in dissolving fibrin clots to promote thrombolysis. The recombinant human plasminogen activator (rhPA) has more thrombolytic advantages than the wild type tPA. To increase the half-life and thrombolytic activity of tPA, a mutant containing only the essential K2 fibrin-binding and P activating plasminogen domains of the wild type tPA was cloned. This fragment was then inserted into goat β-casein regulatory sequences. Then, a mammary gland-specific expression vector, PCL25/rhPA, was constructed, and the transgenic rabbits were generated. In this study, 18 live transgenic founders (12♀, 6♂) were generated using pronuclear microinjection. Six transgenic rabbits were obtained, and the expression levels of rhPA in the milk had a range of 15.2-630 µg/ml. A fibrin agarose plate assay of rhPA showed that it had strong thrombolytic bioactivity in vitro, and the highest specific activity was >360 (360 times more than that of alteplase). The results indicated that the rhPA containing only the K2 and P domains is efficiently expressed with higher thrombolytic bioactivity in the milk of transgenic rabbits. Our study also demonstrated a new method for the large-scale production of clinically relevant recombinant pharmaceutical proteins in the mammary glands of transgenic rabbits.

Therapy dropout is a common occurrence, especially in adolescence. This study investigated whether dropout could be predicted from a range of child, family, and treatment factors in a sample of adolescents receiving therapy for depression. This study draws on data from 406 participants of the IMPACT study, a randomized controlled trial, investigating three types of therapy in the treatment of adolescent depression. Logistic regression was used to estimate the effects of predictors on the odds of dropout. Few pre-treatment predictors of dropout were found, with the only significant predictors being older age, antisocial behaviour, and lower scores of verbal intelligence. Missed sessions and poorer therapeutic alliance early in treatment also predicted dropout. Most child and family factors investigated were not significantly associated with dropout. There may be little about depressed adolescents' presentation prior to therapy starting that indicates their risk of dropout. However, within-treatment factors indicated that warning signs of dropout may be identifiable during the initial phase of therapy. Identifying and targeting early treatment indicators of dropout may provide possibilities for improving engagement. Clinical and methodological significance of this article: In the literature, a great deal of attention has been paid to child and family factors that predict therapy dropout, yet in this study, few pre-treatment characteristics were predictive of dropout. However, findings revealed possible warning signs of dropout in the early part of treatment, as poor therapeutic alliance and missed sessions were both found to be predictive of dropout. These findings call for therapists to be aware of such warning signs and clinical guidelines for managing cases at risk of dropout are warranted.

Hyperglycemia, Acute Ischemic Stroke and Thrombolytic Therapy

Ischemic stroke is a leading cause of disability and is considered now the 4th leading cause of death. Many clinical trials have shown that stroke patients with acute elevation in blood glucose at onset of stroke suffer worse functional outcomes, longer in-hospital stay and higher mortality rates. The only therapeutic hope for these patients is the rapid restoration of blood flow to the ischemic tissue through intravenous administration of the only currently proven effective therapy, tissue plasminogen activator (tPA). However, even this option is associated with the increased risk of intracerebral hemorrhage. Nonetheless, the underlying mechanisms through which hyperglycemia (HG) and tPA worsen the neurovascular injury after stroke are not fully understood. Accordingly, this review summarizes the latest updates and recommendations about the management of HG and co-administration of tPA in a clinical setting while focusing more on the various experimental models studying: 1. the effect of HG on stroke outcomes; 2. the potential mechanisms involved in worsening the neurovasular injury; 3. the different therapeutic strategies employed to ameliorate the injury, and finally; 4. the interaction between HG and tPA. Developing therapeutic strategies to reduce the hemorrhage risk with tPA in hyperglycemic setting is of great clinical importance. This can best be achieved by conducting robust preclinical studies evaluating the interaction between tPA and other therapeutics in order to develop potential therapeutic strategies with high translational impact.

In this paper an MR-guided focused pulsed ultrasound system for the treatment of stroke using thrombolytic drugs in a model in vitro is presented. A single element spherically focused transducer of 5 cm diameter; focusing at 10 cm and operating at 0.5 MHz or 1 MHz was used. The transducer was mounted in an MR compatible robot. The artery was modelled using a silicone tube. Tissue was modelled using polyaclylimide gel. Coagulated blood was used to model thrombus. A thermocouple was placed in the thrombus in order to measure the thrombus temperature. The effect of power, beam, and frequency was investigated. The goal was to maintain a temperature increase of less than 1 °C during the application of pulse ultrasound (called safe temperature). With the application of ultrasound alone there was no notable destruction of the thrombus. With the combination of ultrasound and thrombolytic drugs destruction occurred after 60 mins of pulse exposure (PRF = 1 s, duty factor = 10%, and with thrombus placed at 1 cm deep in the tissue). This simple in vitro model was proven very successful for evaluating MRgFUS as a modality for treating stroke. In the future we plan to apply this treatment protocol in live animals and humans.

Reperfusion therapy in ST-segment elevation myocardial infarction in the Veteran Administration Caribbean Healthcare System; search for improvement.

Patients that present with acute STEMI have proven morbidity and mortality benefit from early reperfusion therapy. The American College of Cardiology/American Heart Association (ACC/AHA) guidelines recommend either fibrinolytic therapy within 30 minutes or a primary percutaneous coronary intervention (PPCI) within 90 minutes of patients arrival to the Emergency Department. Despite these recommendations, some patients do not receive reperfusion therapy and less than half receive it on time. Describe and analyze our reperfusion therapy performance in patients presenting with acute ST segment elevation myocardial infarct (STEMI) in the Veteran Administration Caribbean Healthcare System (VACHS), and determine potential causes for reperfusion therapy delays and develop strategies and a tailored algorithm according to our clinical findings and available institutional resources. Retrospective analysis of patients admitted to the VACHS with a discharge diagnosis of STEMI, from 01/01/2007 until 04/10/2008. A total of 55 patients met inclusion criteria for STEMI diagnosis. Of these, only 30 patients had active indication for reperfusion therapy. Reperfusion therapy was given in 97% of the cases, 69% with PPCI and 31% with fibrinolytic therapy (tenecteplase). In general the selection of reperfusion therapy seemed adherent to ACC/AHA STEMI guidelines. The reperfusion time goal was superior with thrombolytic therapy compared to PPCI, with 43% and 15% respectively. PPCI performed off regular tour of duty was significantly delayed compared to regular day shift, with a mean time of 221 and 113 minutes respectively (p=0.027). Most of the patients presenting with STEMI to the VACHS undergo reperfusion therapy. PPCI was the most frequent selected reperfusion approach. The PPCI time goal was infrequently met. The most significant cause for PPCI delay was related to performance off regular tour of duty. These finding support the implementation of a tailored STEMI reperfusion algorithm

Callistemon citrinus (Curtis.) (Family- Myrtaceae) is a popular evergreen shrub in Bangladesh. In the present study, the leaves of this plant have been assessed comprehensively for free radical scavenging, thrombolytic and membrane stabilizing activities. The leaves were collected, powdered and extracted with methanol. The extract was then concentrated and successively fractionated into petroleum ether, carbon tetrachloride, chloroform and aqueous soluble fractions. The extractives were investigated for free radical scavenging, thrombolytic and membrane stabilizing activities. In case of 1,1 diphenyl-2-picrylhydrazyl (DPPH) and hydrogen peroxide radical scavenging assays, the crude methanol extract of the leaves showed the highest free radical scavenging activity among the tested materials including standard ascorbic acid (p = 0.0000). Besides, this extract was also found significantly rich (p = 0.0000) in phenolics and flavonoids compared to other organic fractions. In thrombolytic study, the petroleum ether fraction exhibited significantly stronger thrombolysis (p = 0.024) than other leaf extractives but was weaker than the standard streptokinase. In membrane stabilizing assay, the activity of chloroform fraction was similar to that of standard acetylsalicylic acid (p = 1.000) in hypotonic solution induced hemolysis. However, membrane stabilization activity of this chloroform fraction was found significantly stronger than that of the standard (p = 0.0000) in heat induced hemolysis. This study has revealed the medicinal capabilities of different organic fractions of C. citrinus displaying free radical scavenging, thrombolysis and membrane stabilizing antiinflammatory potentials. Further bioactivity guided isolation is required to obtain pharmacologically secondary metabolites.

Electrocardiographic evaluation of reperfusion therapy in patients with acute myocardial infarction.

The present thesis is based on 6 previously published clinical studies in patients with AMI. Thrombolytic therapy for patients with AMI improves early infarct coronary artery patency, limits AMI size, improves left ventricular function and survival, as demonstrated in large placebo-controlled clinical trials. With the advent of interventions aimed at limiting AMI size it became important to assess the amount of ischemic myocardium in the early phase of AMI, and to develop noninvasive methods for evaluation of these therapies. The aims of the present studies were to develop such methods. The studies have included 267 patients with AMI admitted up to 12 hours after onset of symptoms. All included patients had acute ECG ST-segment changes indicating subepicardial ischemia, and patients with bundle branch block were excluded. Serial ECG's were analyzed with quantitative ST-segment measurements in the acute phase and compared to the Selvester QRS score estimated final AMI size. These ECG indices were compared to and validated through comparisons with other independent noninvasive and invasive methods, used for the purpose of evaluating patients with AMI treated with thrombolytic therapy. It was found that in patients with first AMI not treated with reperfusion therapies the QRS score estimated final AMI size can be predicted from the acute ST-segment elevation. Based on the number of ECG leads with ST-segment elevation and its summated magnitude, formulas were developed to provide an "ST score" for estimating the amount of myocardium in jeopardy during the early phase of AMI. The ST-segment deviation present in the ECG in patients with documented occlusion of the infarct related coronary artery, was subsequently shown to correlate with the degree of regional and global left ventricular dysfunction. Because serial changes in ST-segment elevation, during the acute phase of AMI were believed to reflect changes is myocardial ischemia and thus possibly infarct artery patency

Background and study aims  Recent literature suggests that chemo(radio)therapy might reduce the patency of plastic stents in patients with malignant biliary obstruction. Whether this might also be valid for other types of stents is unknown. The aim of this study was to determine the influence of chemo(radio)therapy on the patency of fully-covered self-expandable metal stents (FCSEMSs) and plastic stents. Patients and methods  We retrospectively reviewed the electronic medical records of patients with distal malignant biliary obstruction who underwent biliary stent placement between April 2001 and July 2015. Primary outcome was duration of stent patency. Secondary outcome was stent patency at 3 and 6 months. We used Kaplan–Meier survival analyses to compare stent patency rates between patients who received chemo(radio)therapy and patients who did not. Results  A total of 291 biliary stents (151 metal and 140 plastic) were identified. The median cumulative stent patency of FCSEMSs did not differ between patients receiving chemo(radio)therapy (n = 51) and those (n = 100) who did not ( P  = 0.70, log-rank test). The estimated cumulative stent patency of plastic stents was also comparable in 99 patients without and 41 patients with chemo(radio)therapy ( P  = 0.73, log-rank test). At 3 and 6 months, FCSEMS patency rates were 87 % and 83 % in patients without chemo(radio)therapy and 96 % and 83 % in patients with therapy, respectively. Plastic patency rates were 69 % and 55 % in patients without and 85 % and 39 % in patients with therapy, respectively. After 1 year, 78 % of the FCSEMSs were still patent in patients without chemo(radio)therapy and 69 % of the FCSEMSs were still patent in patients with therapy. Conclusion  Our data indicate that chemo(radio)therapy does not reduce the patency of biliary fully-covered metal and plastic stents. PMID:29090242

To assess the effect of adherence to antiretroviral therapy on the duration of virological suppression after controlling for whether or not the patient ever attained a plasma viral load below the limit of detection of sensitive HIV-1 RNA assays. Data were combined from three randomized, blinded clinical trials (INCAS, AVANTI-2, and AVANTI-3) that compared the antiviral effects of two- and three-drug antiretroviral regimens. Virological suppression was defined as maintaining a plasma viral load below 1000 copies/mL. Adherence was defined prospectively and measured by patient self-report. Adherence did not have a major impact on the probability of achieving virological suppression for patients receiving dual therapy. However, for patients receiving triple therapy, adherence increased the probability of virological suppression, whether the plasma viral load nadir was above or below the lower limit of quantification. Compared to adherent patients with a plasma viral load nadir below the lower limit of quantification, the relative risk of virological failure was 3.0 for non-adherent patients with a nadir below the limit, 18.1 for adherent patients with a nadir above the limit, and 32.1 for non-adherent patients with a nadir above the limit. For patients receiving current three-drug antiretroviral regimens, adherence to therapy and plasma viral load nadir are important factors determining the duration of virological suppression.

Studies have rarely compared health outcomes for patients with breast cancer at different treatment stages. The purpose of the study was to compare symptoms and quality of life among patients with breast carcinoma receiving target, chemotherapy, or combined therapy. A longitudinal study was carried out with 57 patients receiving chemotherapy, 30 receiving target therapy, and 34 receiving combined therapy. Data were collected before the start of treatment, at 4 weeks, and at 12 weeks following the start of treatment. Symptom severity and interference were assessed by the M. D. Anderson Symptom Inventory. The physical and mental components of quality of life (physical component score [PCS] and mental component score [MCS]) were assessed using SF-36. There were no significant differences in symptom severity and interference for patients in the 3 therapy groups. The PCSs did not differ significantly according to the therapy group but did decrease significantly after each treatment. Patients receiving target therapy had significantly higher MCSs than did patients receiving chemotherapy, but the MCSs did not differ significantly before and after the treatment. Patients with higher symptom severity and interference had worse PCS and MCS. Patients at all treatment groups had worse physical components quality of life after treatment as compared with before treatment. Patients receiving target therapy had better mental components of quality of life. The mental components of quality of life remained stable during treatment. Nurses should assess the patients' symptoms during treatment and provide timely intervention to optimize their quality of life.

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. 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. 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. These results suggest that the ATM polymorphisms might serve as independent biomarkers for predicting prognosis in ESCC patients receiving radiation therapy. Copyright © 2015 Elsevier Inc.

Changes in endogenous microflora among febrile granulocytopenic patients receiving empiric antibiotic therapy: implications for fungal superinfection.

The ecologic effect of empiric systemic antibiotic therapy on the endogenous microflora was evaluated in 83 febrile granulocytopenic patients with cancer who were randomly allocated to receive moxalactam plus ticarcillin (45 patients) or tobramycin plus ticarcillin (38 patients) for suspected infection. Serial surveillance cultures of the nasal passages, oropharynx and feces performed twice a week showed that patients who received the former regimen had higher elimination rates and significantly lower acquisition rates (p = 0.027) for aerobic gram-negative bacilli than did patients who received the latter regimen. However, therapy with moxalactam plus ticarcillin also resulted in significantly higher acquisition rates for yeasts (p = 0.004). This was associated with a significantly higher fungal superinfection rate among these patients than among those who received tobramycin plus ticarcillin (40% v. 16%) (p less than 0.05). Moxalactam plus ticarcillin therapy created a greater microbial ecologic vacuum by the elimination of intestinal anaerobes, which, in turn, permitted fungal colonization and an increased risk of superinfection. Our results support the recommendation that an antipseudomonal penicillin plus an aminoglycoside be selected as empiric therapy for suspected infection in febrile granulocytopenic patients with cancer. Such a regimen would spare the anaerobic intestinal microflora, thereby reducing the risk of fungal colonization and infection. PMID:3304600

Stroke is deemed a worldwide leading cause of neurological disability and death, however, there is currently no promising pharmacotherapy for acute ischemic stroke aside from intravenous or intra-arterial thrombolysis. Yet because of the narrow therapeutic time window involved, thrombolytic application is very restricted in clinical settings. Accumulating data suggest that non-pharmaceutical therapies for stroke might provide new opportunities for stroke treatment. Here we review recent research progress in the mechanisms and clinical implications of non-pharmaceutical therapies, mainly including neuroprotective approaches such as hypothermia, ischemic/hypoxic conditioning, acupuncture, medical gases, transcranial laser therapy, etc. In addition, we briefly summarize mechanical endovascular recanalization devices and recovery devices for the treatment of the chronic phase of stroke and discuss the relative merits of these devices.

Aerosol therapy, a treatment for children with disorders of the respiratory system, often causes distress, especially in young children. Distress during aerosol therapy can decrease the effectiveness of the treatment. This study aimed to determine the effect of audiovisual distraction on distress levels and oxygenation status (measured by oxygen saturation and respiratory frequency) in children who receive aerosol therapy for disorders of the respiratory system. A quasi-experimental design was employed, specifically a non-equivalent control group, pre-test-post-test design. The study sample consisted of 38 children who were divided into 2 groups (control and intervention), each group consisting of 19 children. The results of this study showed that there were significant differences in distress scores between the control group and the intervention group (p = .0001). There were also significant differences in the mean value changes in oxygenation status before and after intervention between the control and intervention groups. These findings could be used to prevent distress and increase oxygenation status in children who receive aerosol therapy.

Trials of salvage therapy for advanced urothelial carcinoma have required prior platinum-based therapy. This practice requires scrutiny because non-platinum-based first-line therapy may be offered to cisplatin-ineligible patients. Data of patients receiving salvage systemic chemotherapy were collected. Data on prior first-line platinum exposure were required in addition to treatment-free interval, hemoglobin, Eastern Cooperative Oncology Group performance status, albumin, and liver metastasis status. Cox proportional hazard regression was used to evaluate their association with overall survival (OS) after accounting for salvage single-agent or combination chemotherapy. Data were obtained from 455 patients previously exposed to platinum-based therapy and 37 not exposed to platinum. In the group exposed to prior platinum therapy, salvage therapy consisted of a single-agent taxane (n = 184) or a taxane-containing combination chemotherapy (n = 271). In the group not exposed to prior platinum therapy, salvage therapy consisted of taxane or vinflunine (n = 20), 5-fluorouracil (n = 1), taxane-containing combination chemotherapy (n = 12), carboplatin-based combinations (n = 2), and cisplatin-based combinations (n = 2). The median OS for the prior platinum therapy group was 7.8 months (95% confidence interval, 7.0, 8.1), and for the group that had not received prior platinum therapy was 9.0 months (95% confidence interval, 6.0, 11.0; P = .50). In the multivariable analysis, prior platinum therapy versus no prior platinum exposure did not confer an independent impact on OS (hazard ratio, 1.10; 95% confidence interval, 0.75, 1.64; P = .62). Prior platinum- versus non-platinum-based chemotherapy did not have a prognostic impact on OS after accounting for major prognostic factors in patients receiving salvage systemic chemotherapy for advanced urothelial carcinoma. Lack of prior platinum therapy should not disqualify patients from inclusion onto trials of salvage

Reducing rectal injury in men receiving prostate cancer radiation therapy: current perspectives

PubMed Central

Serrano, Nicholas A; Kalman, Noah S; Anscher, Mitchell S

2017-01-01

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

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.

A subset of patients who present with metastatic solid tumors never receive anticancer therapy. Reasons may include poor functional status, comorbidities, and patient preference. To the authors' knowledge, the prevalence and characteristics of this population have not previously been described. The National Cancer Data Base was queried for patients diagnosed with metastatic (stage IV according to the American Joint Committee on Cancer) solid tumors (including those of the breast, cervix, colon, and kidney; small cell and nonsmall cell lung cancer [NSCLC]; and tumors of the prostate, rectum, and uterus) who received neither radiotherapy nor systemic therapy. Log-binomial regression analysis was used to estimate prevalence ratios (PRs) for the percentage of untreated to treated patients with stage IV cancer. Between 2000 and 2008, 773,233 patients with stage IV cancer were identified, 159,284 of whom (20.6%; 95% confidence interval, 20.5%-20.7%) received no anticancer therapy. Patients with NSCLC accounted for 55% of the untreated population. Patients with cancers of the kidney and lung had the highest rates of no treatment at 25.5% and 24.0%, respectively, whereas patients with prostate cancer had the lowest rate of no treatment at 11.1%. Across all cancer types, older age (PR range, 1.37-1.49; all P < .001), black race (PR range, 1.05-1.32; all P < .001), lack of medical insurance (PR range, 1.47-2.46; all P < .001), and lower income (except for cancer of the uterus; PR range, 0.91-0.98 for every $10,000-increase in income [all P < .001]) were associated with a lack of treatment. Approximately 20% of patients who present with stage IV solid tumors do not receive anticancer therapy. Although there are likely multiple reasons for this lack of treatment, including appropriate indications, these findings have potential implications with regard to health care policy and access to care.

SAK-RGD-K2-Hir and SAK-RGD-K2-Hirul are recombinant proteins that are derivatives of r-SAK (recombinant staphylokinase). They are characterized by their fibrin-specific plasminogen activation properties and their antithrombin and antiplatelet activities. The difference between these proteins is the presence of the antithrombotic fragment (hirudin or hirulog) in the C-terminal portion of the r-SAK. The aim of the present study was to examine the thrombolytic potentials of SAK-RGD-K2-Hir and SAK-RGD-K2-Hirul in an electrically induced carotid artery thrombosis model in rats and to compare the potentials to that of r-SAK. We determined that a bolus injection of SAK-RGD-K2-Hirul was more effective than one of r-SAK in the improvement and maintenance of carotid patency and in arterial thrombus weight reduction; however, it had the same potency as SAK-RGD-K2-Hir. The bleeding time, prothrombin time and activated partial thromboplastin time were significantly prolonged in the animals that were treated with either dose (1.5 or 3.0 mg/kg) of SAK-RGD-K2-Hir or SAK-RGD-K2-Hirul, whereas no changes were observed in the plasma fibrinogen concentration or the α2 plasmin inhibitor level. r-SAK alone did not change the bleeding time or coagulation parameters. In conclusion, our findings demonstrate the thrombolytic activity of intravenous bolus injection of the novel thrombolytic agent SAK-RGD-K2-Hirul in rats. Although this protein compares favorably with r-SAK, we were unable to show the presence of any beneficial effects of SAK-RGD-K2-Hirul over those of SAK-RGD-K2-Hir. Furthermore, our results suggest that high doses of SAK-RGD-K2-Hirul bear the risk of bleeding.

Clopidogrel (Plavix(®)) may influence patient safety during fracture surgery. Our study examines the incidence of complications for patients undergoing hemiarthroplasty on clopidogrel therapy. All patients, who underwent hemiarthroplasty between 2005 and 2011 were retrospectively reviewed. Patients were placed in two comparative groups based on the use of clopidogrel antiplatelet therapy. Records were reviewed for patient demographics, ASA score, pre and postoperative hemoglobin, time to surgery, length of stay, bleeding events, transfusions and complications. Comparative statistical analysis was performed using Fisher's exact test and Student's t test, using P < 0.05 to identify statistical significance. A total of 203 charts were reviewed, of which 162 patients met inclusion/exclusion criteria. One hundred and twelve females and 50 males with mean age of 84 years were identified. The clopidogrel group consisted of 15 (9.3 %) patients and the nonclopidogrel group 147 (90.7 %). The clopidogrel group had more comorbidities resulting in a significantly higher ASA score (3.9 vs. 2.9), and lower preoperative hemoglobin (11.3 vs. 12.0). There was no significant difference identified in time to surgery, intraoperative blood loss, hemoglobin on days 1-3, or number of transfusions received between groups. Patients on clopidogrel were seen to have significantly longer hospital stays (10.6 vs. 7.4 days). However, a similar rate of wound and bleeding related complications (6.7 vs. 6.1 %) was seen. The optimal treatment for hip fracture patients on antiplatelet therapy is unclear. However, in this study there appears to be no significant difference with regards to bleeding and bleeding related wound complications, suggesting it is safe to proceed with hemiarthroplasty for patients receiving clopidogrel.

Cardiogenic shock complicating acute myocardial infarction (AMI) remains the leading cause of death in patients hospitalized with AMI. Although several studies have demonstrated the importance of establishing and maintaining a patent infarct-related artery, it remains unclear as to whether intra-aortic balloon counterpulsation (IABP) provides incremental benefit to reperfusion therapy. The purpose of this study was to determine whether IABP use is associated with lower in-hospital mortality rates in patients with AMI complicated by cardiogenic shock in a large AMI registry. We evaluated patients participating in the National Registry of Myocardial Infarction 2 who had cardiogenic shock at initial examination or in whom cardiogenic shock developed during hospitalization (n = 23,180). The mean age of patients in the study was 72 years, 54% were men, and the majority were white. The overall mortality rate in all patients who had cardiogenic shock or in whom cardiogenic shock developed was 70%. IABP was used in 7268 (31%) patients. IABP use was associated with a significant reduction in mortality rates in patients who received thrombolytic therapy (67% vs 49%) but was not associated with any benefit in patients treated with primary angioplasty (45% vs 47%). In a multivariate model, the use of IABP in conjunction with thrombolytic therapy decreased the odds of death by 18% (odds ratio, 0.82; 95% confidence interval, 0.72 to 0.93). Patients with AMI complicated by cardiogenic shock may have substantial benefit from IABP when used in combination with thrombolytic therapy.

We aimed to compare the rates of thrombolysis utilization for acute ischemic stroke in hospitals with neurology residency (NR) to those of other teaching (OT) and nonteaching (NT) hospitals. A retrospective serial cross-sectional cohort study of a nationally representative sample of stroke patients was conducted. Accreditation Council for Graduate Medical Education-accredited NR program-affiliated hospitals in the United States were cross-matched to the hospitals in the Nationwide Inpatient Sample from 2000 to 2010. ICD-9-CM codes were used for case ascertainment. A total of 712,433 adult ischemic stroke patients from 6,839 hospital samples were included, of whom 10.1%, 29.1%, and 60.8% were treated in NR, OT, and NT hospitals, respectively. Stroke patients in NR received thrombolysis more frequently (3.74% ± 0.24% [standard error]) than in OT (2.28% ± 0.11%, p < 0.001) and NT hospitals (1.44% ± 0.06%, p < 0.001). The adjusted odds ratios (ORs) of thrombolysis rates in NR vs OT and NR vs NT increased with each decade increment in age. In multivariate analysis, NR was independently predictive of higher thrombolysis rate (adjusted OR 1.51; 95% confidence interval [CI] 1.44-1.59 [NR vs OT], and adjusted OR 1.82; 95% CI 1.73-1.91 [NR vs NT]). Acute stroke care in NR hospitals is associated with an increased thrombolytic utilization. The disparities between the thrombolysis rate in NR and that in OT and NT hospitals are greater among elderly patients.

Streptokinase (SK) is an extracellular enzyme secreted by various strains of β-hemolytic Streptococci. The main focus of the current study is to evaluate the in vitro thrombolytic activity of purified SK extracted from Streptococcus equinus VIT_VB2 (Accession no. JX406835) isolated from milk sample. The growth rate of S. equinus VIT_VB2 strain was studied with pH and biomass content which has positive significant effect on enzyme yield. A temperature of 10 °C and pH of 6 was found to be optimum for maximum SK activity. The specific activity of the purified SK produced by VIT_VB2 strain was found to be 6,585 IU mg(-1). The molecular mass of the enzyme was determined as 47 kDa by SDS-PAGE. In vitro thrombolytic activity of purified SK was determined using synthetic chromogenic substrate S-2251, the activity of the purified enzyme was found to be 6,330 ± 2.2 IU. The purity of SK was compared with standard SK by HPLC. This is the first report which reveals the SK activity of S. equinus isolated from milk sample.

This study analyzed the use of music therapy for residents in nursing homes receiving hospice care. An ex-post facto design was utilized to evaluate participants' length of life on the hospice program, time of death in relation to last visit by the social worker and music therapist, the number of sessions and total number of minutes spent in direct care by the social worker and music therapist, and care plan needs treated by the nurse, social worker, and music therapist. A total of 80 participants' medical records were randomly selected for this study. All participants were in nursing homes, 40 of whom had been referred to music therapy. Results showed no significant differences on the time of death in relation to last visit by hospice professional, but there were significant differences in the length of life for those receiving music therapy. Females in this study lived significantly longer than males. Participants received significantly more music therapy sessions than social work sessions, and music therapists spent significantly more time in direct care with participants than did social workers. Care plan needs were analyzed graphically and indicate that music therapists meet important needs of participants.

The aim of this work was to evaluate receptive and expressive language skills in children with congenital hypothyroidism receiving early hormonal replacement treatment before the age of 3 months and to identify any subtle areas of weaknesses in their language development to check the necessity for future language intervention. The study was conducted on 30 hypothyroid children receiving hormonal replacement. They were subdivided into group I (5-8 years 11 months; 12 cases) and group II (9-12 years 11 months; 18 cases). All patients were subjected to a protocol of assessment applied in the Diabetes, Endocrine and Metabolism Pediatric Unit (DEMPU) and evaluation of language skills by the REAL scale. The younger group reached average Arabic language scores, while the older group showed moderate language delay. Early replacement therapy supports language development in young children. However, longitudinal and follow-up studies are required to identify difficulties presenting at older ages that may affect children in the academic settings. © 2016 S. Karger AG, Basel.

To test the effects of a brief psychosocial intervention using CD-ROM (BPIC) on psychosocial (fighting spirit, helplessness or hopelessness, anxiety, and depression) and behavioral (self-care behaviors) outcomes in patients with cancer receiving adjuvant therapy. Quasi-experimental. A comprehensive cancer center in Seoul, South Korea. 71 patients undergoing adjuvant therapy. The study participants were assigned to either BPIC or a control group. The experimental group underwent a two-week psychosocial intervention via CD-ROM, booklet, and telephone counseling. Fighting spirit, helplessness or hopelessness, anxiety, depression, and self-care behaviors. After BPIC, the experimental group showed significantly higher scores than the control group for fighting spirit (p = 0.005) and self-care behaviors (p < 0.001). However, the groups showed no significant differences in helplessness or hopelessness (p = 0.42), anxiety (p = 0.279), and depression (p = 0.068). BPIC use improved fighting spirit and self-care behaviors in study participants. The results partially support the effectiveness of BPIC for adaptation among patients with cancer receiving adjuvant therapy. A brief psychosocial intervention using multimedia can be used effectively in clinical oncology settings to accelerate adaptation among patients with cancer in the adjuvant phase.

Timely administration of thrombolytic therapy is critical to maximizing the likelihood of favorable outcomes in patients with acute ischemic stroke. Although emergency medical service activation overall improves the timeliness of acute stroke treatment, the time from emergency medical service dispatch to hospital arrival unavoidably decreases the timeliness of thrombolytic administration. Our mobile stroke unit, a new-generation ambulance with on-board CT scanning capability, reduces key imaging time metrics and facilitates in-the-field delivery of IV thrombolytic therapy. © 2018 by American Journal of Neuroradiology.

A comparison of the enzymatic properties of three recombinant isoforms of thrombolytic and antibacterial protein--Destabilase-Lysozyme from medicinal leech.

Destabilase-Lysozyme (mlDL) is a multifunctional i-type enzyme that has been found in the secretions from the salivary glands of medicinal leeches. mlDL has been shown to exhibit isopeptidase, muramidase and antibacterial activity. This enzyme attracts interest because it expresses thrombolytic activity through isopeptidolysis of the ε-(γ-Glu)-Lys bonds that cross-link polypeptide chains in stabilised fibrin. To date, three isoforms of mlDL have been identified. The enzymatic properties of pure mlDL isoforms have not yet been described because only destabilase complexes containing other proteins could be isolated from the salivary gland secretion and because low product yield from the generation of recombinant proteins has made comprehensive testing difficult. In the present study, we optimised the procedures related to the expression, isolation and purification of active mlDL isoforms (mlDL-Ds1, mlDL-Ds2, mlDL-Ds3) using an Escherichia coli expression system, and we detected and compared their muramidase, lytic, isopeptidase and antimicrobial activities. After optimisation, the product yield was 30 mg per litre of culture. The data obtained in our study led to the suggestion that the recombinant mlDL isoforms isolated from inclusion bodies form stable oligomeric complexes. Analyses of the tested activities revealed that all isoforms exhibited almost identical patterns of pH and ionic strength effects on the activities. We determined that mlDL-Ds1, 2, 3 possessed non-enzymatic antibacterial activity independent of their muramidase activity. For the first time, we demonstrated the fibrinolytic activity of the recombinant mlDL and showed that only intact proteins possessed this activity, suggesting their enzymatic nature. The recombinant Destabilase-Lysozyme isoforms obtained in our study may be considered potential thrombolytic agents that act through a mechanism different from that of common thrombolytics.

We assessed antiplatelet therapy use and outcomes in patients undergoing percutaneous coronary intervention (PCI) during the ARISTOTLE trial. Patients were categorized based on the occurrence of PCI during follow-up (median 1.8 years); PCI details and outcomes post-PCI are reported. Of the 18,201 trial participants, 316 (1.7%) underwent PCI (152 in apixaban group, 164 in warfarin group). At the time of PCI, 84% (267) were on study drug (either apixaban or warfarin). Of these, 19% did not stop study drug during PCI, 49% stopped and restarted <5 days post-PCI, and 30% stopped and restarted >5 days post-PCI. At 30 days post-PCI, 35% of patients received dual -antiplatelet therapy (DAPT), 23% received aspirin only, and 13% received a P2Y 12 inhibitor only; 29% received no antiplatelet therapy. Triple therapy (DAPT + oral anticoagulant [OAC]) was used in 21% of patients, 23% received OAC only, 15% received OAC plus aspirin, and 9% received OAC plus a P2Y 12 inhibitor; 32% received antiplatelet agents without OAC. Post-PCI, patients assigned to apixaban versus warfarin had numerically similar rates of major bleeding (5.93 vs 6.73 events/100 patient-years; P = .95) and stroke (2.74 vs 1.84 events/100 patient-years; P = .62). PCI occurred infrequently during follow-up. Most patients on study drug at the time of PCI remained on study drug in the peri-PCI period; 19% continued the study drug without interruption. Antiplatelet therapy use post-PCI was variable, although most patients received DAPT. Additional data are needed to guide the use of antithrombotics in patients undergoing PCI.

Maturing techniques have spurred widespread implementation of endovascular embolectomy therapy for ischemic stroke. We evaluated a large administrative database to determine outcomes in patients treated with endovascular embolectomy in the general population. Using the National Inpatient Sample, we evaluated outcomes of patients treated for acute ischemic stroke in the United States from 2006 to 2008. Patients who had an ischemic stroke and underwent endovascular clot retrieval were identified. Morbidity, defined as "discharge to long-term facility," and mortality were evaluated as a function of patient age and of concomitant thrombolytic agent administration. For 2006 to 2008, a total of 3864 patients received endovascular clot retrieval with 266 (6.9%) patients in 2006, 800 (20.7) patients in 2007, and 2798 (72.4%) patients in 2008. The discharge to a long-term facility rate was 51.3% (1983 of 3864). The in-hospital mortality rate was 24.3% (940 of 3864). For patients <65 years old, the rate of in-hospital death was 17.1% (283 of 1658) as compared with a rate of 29.7% (656 of 2206) for patients ≥65 years old (P<0.0001). The rate of discharge to a long-term facility was 47.6% (789 of 1658) for patients <65 years old and 54.1% (1193 of 2206) for patients ≥65 years old (P<0.0001). The rate of intracranial hemorrhage was 15.5% without concomitant thrombolysis and 20.0% with concomitant thrombolysis (P=0.0009). Rates of morbidity and mortality remain high for patients with acute stroke, even in the setting of endovascular embolectomy. Advanced age portends a worse outcome and patients treated with concomitant use of thrombolytic agent had higher rates of intracranial hemorrhage than those without such therapy.

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

Background The objectives of our study were to examine long-term (1986–2003) trends in the use of percutaneous coronary interventions (PCI) and thrombolytic therapy in the management of patients hospitalized at all Central Massachusetts medical centers with acute myocardial infarction (AMI). Our secondary study goal was to examine factors associated with use of these coronary reperfusion strategies. Limited contemporary data are available about changing trends in the use of coronary reperfusion strategies, particularly from a population-based perspective. Methods The sample consisted of 9,422 greater Worcester (MA) residents hospitalized with AMI at all metropolitan Worcester medical centers in 10 annual periods between 1986 and 2003. Results Divergent trends in the use of PCI and thrombolytic therapy during hospitalization for AMI were noted. Use of thrombolytic therapy increased after its introduction to clinical practice in the mid-1980’s through the early 1990’s with a progressive decline in use thereafter. In 2003, 3.5% of patients hospitalized with AMI were treated with clot lysing therapy. Marked increases in the use of PCI during hospitalization for AMI were noted over time. In 2003, 42.1% of patients with AMI received a PCI. Several demographic and clinical factors were associated with the use of these different treatment strategies. Conclusions The results of our study in a large New England (United States) community suggest evolving changes in the hospital management of patients with AMI. Current management practices emphasize the utilization of PCI to restore coronary reperfusion to the infarct related artery. PMID:18191479

The aim of this study was to investigate if relaxing music is an effective method of reducing the physiological signs of anxiety in patients receiving mechanical ventilatory support. Few studies have focused on the effect of music on physiological signs of anxiety in patients receiving mechanical ventilatory support. A study-case-control, experimental repeated measures design was used. Sixty patients aged 18-70 years, receiving mechanical ventilatory support and hospitalised in the intensive care unit, were taken as a convenience sample. Participants were randomised to a control group or intervention group, who received 60 minutes of music therapy. Classical music was played to patients using media player (MP3) and headphones. Subjects had physiological signs taken immediately before the intervention and at the 30th, 60th and 90th minutes of the intervention. Physiological signs of anxiety assessed in this study were mean systolic and diastolic blood pressure, pulse rate, respiratory rate and oxygen saturation in blood measured by pulse oxymetry. Data were collected over eight months in 2006-2007. The music group had significantly lower respiratory rates, and systolic and diastolic blood pressure, than the control group. This decrease improved progressively in the 30th, 60th and 90th minutes of the intervention, indicating a cumulative dose effect. Music can provide an effective method of reducing potentially harmful physiological responses arising from anxiety. As indicated by the results of this study, music therapy can be supplied to allay anxiety in patients receiving mechanical ventilation. Nurses may include music therapy in the routine care of patients receiving mechanical ventilation. © 2011 Blackwell Publishing Ltd.

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.

To investigate the prognostic value of electrodiagnostic testing in patients with sciatica receiving physical therapy. Electrodiagnostic testing was performed on 38 patients with sciatica participating in a randomized trial comparing different physical therapy interventions. Patients were grouped and analyzed according to the presence or absence of radiculopathy based on electrodiagnostic testing. Longitudinal data analysis was conducted using multilevel growth modeling with ten waves of data collected from baseline through the treatment and post-treatment periods up to 6 months. The primary outcome measure was changes in low back pain-related disability assessed using the Roland and Morris disability questionnaire (RMDQ). Patients with radiculopathy (n = 19) had statistically significant and clinically meaningful improvements in RMDQ scores at every post-treatment follow-up occasion regardless of treatment received. The final multilevel growth model revealed improvements in RMDQ scores in patients with radiculopathy at the 6-week (-8.1, 95 % CI -12.6 to -2.6; P = 0.006) and 6-month (-4.1, 95 % CI -7.4 to -0.7; P = 0.020) follow-up occasions compared to patients without radiculopathy. Treatment group was not a significant predictive factor at any follow-up occasion. An interaction between electrodiagnostic status and time revealed faster weekly improvements in RMDQ scores in patients with radiculopathy at the 6-week (-0.72, 95 % CI -1.4 to -0.04; P = 0.040) through the 16-week (-0.30, 95 % CI, -0.57 to -0.04; P = 0.028) follow-up occasions compared to patients without radiculopathy. The presence of lumbosacral radiculopathy identified with electrodiagnostic testing is a favorable prognostic factor for recovery in low back pain-related disability regardless of physical therapy treatment received.

The potential for hypothermia as a neuroprotectant during stroke has led to its increase in clinical use. At the same time, combination pharmaceutical therapies for ischemic stroke using recombinant tissue plasminogen activator (rt-PA), and GP IIb-IIIa inhibitors, such as Eptifibatide (Epf ), are under study. However, there is little data on how the reactions triggered by these agents are impacted by temperature. Here, clot lysis during exposure to the combination of rt-PA and Epf is measured in an in vitro human clot model at hypothermic temperatures. The hypothesis is that lytic efficacy of rt-PA and Epf decreases with decreasing temperature. Whole blood clots from 31 volunteers were exposed to rt-PA (0.5 μg/mL) and Epf (0.63 μg/mL) in human fresh-frozen plasma (rt-PA+Epf ), rt-PA alone in plasma (rt-PA Alone), or to plasma alone (Control), at temperatures from 30°C to 37°C, for 30 minutes. Clot lysis was measured using a microscopic imaging technique; the mean fractional clot loss (FCL) at 30 minutes was used to determine lytic efficacy. Temperature had a significant impact on FCL in clots exposed to rt-PA+Epf, with the FCL being lower at 30°C to 36°C than at 37°C. The FCL remained significantly higher for rt-PA+Epf–treated clots than Controls regardless of temperature, with the exception of measurements made at 30°C when no significant differences in the FCL were observed between groups. The use of hypothermia as a neuroprotectant may negatively impact the therapeutic benefit of thrombolytic agents.

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. 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. 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. In continuous variables, AFP could have higher predictive accuracy for survival in HCC patients undergoing sorafenib therapy.

The purpose of this placebo-controlled, randomized, double-blinded, parallel study was to determine the existence and magnitude of effect of various doses of fish oil supplements on International Normalized Ratio (INR) determinations in patients receiving chronic warfarin therapy. Patients from anticoagulation clinics from both the Brady Green Community Health Center and Audie L. Murphy Veterans Administration in San Antonio, Texas were enrolled in the study. The enrolled subjects included 5 males and 11 females, all of whom were receiving chronic warfarin therapy for indications requiring oral anticoagulation. All enrolled patients underwent a 4-week placebo monitoring period in which INRs were determined on a weekly basis. If the INRs were found to be stable, patients were randomized to receive a 4-week treatment period of either placebo capsules (n = 6), 3 grams of fish oil daily (n = 5), or 6 grams of fish oil daily (n = 5). Patients were followed on a twice-weekly basis for INR determinations and adverse reactions. Five patients were discontinued from the study due to noncompliance (2) and unstable INRs (3). There was no statistically significant difference in INRs between the placebo lead-in and treatment period within each group (P = 0.82). There was also no difference in INRs found between groups (P= 0.41). One bruising episode was reported, yet no major bleeding episodes were observed during the study. Fish oil supplementation in doses of 3-6 grams per day does not seem to create a statistically significant effect on the anticoagulation status of patients receiving chronic warfarin therapy.

Depression is believed to be a common side effect in patients receiving beta-blocker therapy. However, diagnoses of depression defined by current diagnostic criteria may not be more common in patients receiving beta-blockers than in patients with the same medical disorder receiving other medications. Seventy-seven patients undergoing elective cardiac catheterization for evaluation of chest pain received a semi-structured diagnostic psychiatric interview. Twenty-one percent of the patients receiving beta-blockers and 33 percent of the patients receiving medications other than beta-blockers met the current American Psychiatric Association criteria for major depressive disorder (DSM-III) (p = NS). The mean heart rate and state anxiety scores for patients taking beta-blockers were significantly lower than those measured in patients taking medications other than beta-blockers. No other medical or demographic differences were observed between the two groups. Despite the methodologic limitations of the study, there does not appear to be a difference in the point prevalence of depression between patients receiving beta-blockers and those receiving other medications.

This paper is considered as the first report on the investigation of nattokinase (NK) release from anionic starch nanospheres. The ultra-small and anionic starch nanospheres were prepared by the method of reverse micro-emulsion crosslinking in this work. Starch nanospheres were characterized through Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM), transmission electron microscopy (TEM) and dynamic light scattering (DLS). Effects of preparation conditions on particle size were studied. The cytotoxicity, biodegradable and vitro thrombolytic behaviors of nattokinase (NK) loaded anionic starch nanospheres were also studied. The results showed that the anionic starch nanospheres are non-toxic, biocompatible and biodegradable. Moreover, the anionic starch nanospheres can protect NK from fast biodegradation hence prolongs the circulation in vivo and can reduce the risk of acute hemorrhage complication by decreasing the thrombolysis rate.

Vietnam has a concentrated HIV epidemic with injection drug use being the dominant mode of HIV transmission. Vietnam has rapidly expanded antiretroviral therapy (ART) and methadone maintenance therapy (MMT). This study aims to analyze ART uptake and retention among male clients receiving MMT in Vietnam in the early phase of the MMT program. The male clients (age ≥18) who were newly enrolled in care or started ART at two HIV clinics in Hanoi (2009 to 2011) and three HIV clinics in Can Tho (2010 to 2012) were included for the analysis. The CD4 lymphocyte count at HIV care enrollment and ART initiation and retention on ART were retrospectively analyzed. The values of those receiving MMT were compared with the values of two groups: those in whom injection drug use (IDU) status was documented, but were not receiving MMT, and all male clients not receiving MMT. To analyze retention, survival analysis with log rank test and Cox proportional hazard model was used. During the study period, 663 adult men were newly enrolled in HIV care (237 had IDU status documented) and 456 initiated ART (167 had IDU status documented). Among those who initiated ART, 28 were receiving MMT. At care enrolment, those receiving MMT had a median CD4 count of 230 (IQR 57-308) cells/mm 3 , while men self-reporting IDU and not receiving MMT and all men not receiving MMT had a median CD4 count of 158 (IQR 50-370) cells/mm 3 and 143 (IQR 35-366) cells/mm 3 , respectively. At ART initiation, men receiving MMT had significantly higher CD4 count with median at 203 (IQR 64-290) cells/mm 3 than men self-reporting IDU and not receiving MMT (80, IQR 40-220, cells/mm 3 , p = 0.038) and all men not receiving MMT (76, IQR 20-199, cells/mm 3 , p = 0.009). Those receiving MMT had a significantly higher retention rate than those self-reporting IDU but not receiving MMT (hazard ratio = 0.18, p = 0.019) and men not receiving MMT (hazard ratio = 0.20, p = 0.041). Our analysis suggests that men

There are limited data regarding clinical and treatment factors associated with radiation pneumonitis (RP) in patients receiving taxane-based trimodality therapy for esophageal cancer. The purpose of this study was to identify predictors of RP in patients undergoing trimodality therapy. We retrospectively reviewed patients undergoing chemoradiation followed by esophagectomy between 2006 and 2011. The association between clinical and dosimetric factors with RP was assessed using χ 2 test and Mann-Whitney U test. Multivariable regression was used to assess the relationship between grade 2+ RP and clinical/dosimetric factors. Receiver operator curves were generated to identify threshold doses for RP. A total of 139 patients were included; 19 (13.7%) patients experienced grade 2+ RP. Patients with upper/middle thoracic tumors (P = .038) and receiving higher radiation doses (P = .038) were more likely to develop grade 2+ RP. There was no association between taxane-based therapy and grade 2+ RP (P = .728). The percent volume of lung receiving 5 Gy (V5; P < .001), 10 Gy (P < .001), 20 Gy (V20; P < .001), and 30 Gy (P < .001) was associated with an increased risk of grade 2+ RP. On multivariable regression, the lung V5 (odds ratio, 1.101; 95% confidence interval, 1.1014-1.195) and V20 (odds ratio, 1.149; 95% confidence interval, 1.1015-1.301) remained associated with grade 2+ RP. A V5 ≤65% and V20 ≤25% were identified as optimal thresholds for increased grade 2+ RP. Dosimetric parameters are strong predictors of symptomatic RP in patients undergoing trimodality therapy for esophageal cancer. Mitigating the risk of RP in these patients should be an important consideration during treatment planning. Copyright © 2016 American Society for Radiation Oncology. Published by Elsevier Inc.

Objectives To evaluate safety of intravenous tissue plasminogen activator (tPA) delivered without dedicated thrombolytic stroke teams. Methods This was a retrospective, observational study of patients treated between 1996 and 2005 at four southeastern Michigan hospital emergency departments (EDs) with a prospectively defined comparison to the National Institute of Neurological Disorders and Stroke (NINDS) tPA stroke study cohort. Main outcome measures were mortality, intracerebral hemorrhage (ICH), systemic hemorrhage, neurologic recovery, and guideline violations. Results Two hundred seventy-three consecutive stroke patients were treated by 95 emergency physicians using guidelines and local neurology resources. One-year mortality was 27.8%. Unadjusted Cox model relative risk of mortality compared to the NINDS tPA treatment and placebo groups was 1.20 (95% confidence interval [CI] = 0.87 to 1.64) and 1.04 (95% CI = 0.76 to 1.41), respectively. Rate of significant ICH by computed tomography criteria was 6.6% (OR 1.03, 95% CI = 0.56 to 1.90 compared to NINDS tPA treatment group). The proportion of symptomatic ICH by two other pre-specified sets of clinical criteria was 4.8% and 7.0%. Rate of any ICH within 36 hours of treatment was 9.9% (relative risk [RR] 0.94, 95% CI = 0.58 to 1.51 compared to NINDS tPA group). Occurrence of major systemic hemorrhage (requiring transfusion) was 1.1%. Functional recovery by the modified Rankin Scale score (mRS 0 to 2) at discharge occurred in 38% of patients with a premorbid disability mRS < 2. Guideline deviations occurred in the ED in 26% of patients and in 25% of patients following admission. Conclusions In these EDs there was no evidence of increased risk with respect to mortality, ICH, systemic hemorrhage, or worsened functional outcome when tPA was administered without dedicated thrombolytic stroke teams. Additional effort is needed to improve guideline compliance. PMID:21040107

Endovascular treatment for acute ischemic stroke patients was recently shown to improve recanalization rates and clinical outcome in a well-defined study population. Intravenous thrombolysis (IVT) alone is insufficiently effective to recanalize in certain patients or of little value in others. Accordingly, we aimed at identifying predictors of recanalization in patients treated with or without IVT. In the observational Acute Stroke Registry and Analysis of Lausanne (ASTRAL) registry, we selected those stroke patients (1) with an arterial occlusion on computed tomography angiography (CTA) imaging, (2) who had an arterial patency assessment at 24 hours (CTA/magnetic resonance angiography/transcranial Doppler), and (3) who were treated with IVT or had no revascularization treatment. Based on 2 separate logistic regression analyses, predictors of spontaneous and post-thrombolytic recanalization were generated. Partial or complete recanalization was achieved in 121 of 210 (58%) thrombolyzed patients. Recanalization was associated with atrial fibrillation (odds ratio , 1.6; 95% confidence interval, 1.2-3.0) and absence of early ischemic changes on CT (1.1, 1.1-1.2) and inversely correlated with the presence of a significant extracranial (EC) stenosis or occlusion (.6, .3-.9). In nonthrombolyzed patients, partial or complete recanalization was significantly less frequent (37%, P < .01). The recanalization was independently associated with a history of hypercholesterolemia (2.6, 1.2-5.6) and the proximal site of the intracranial occlusion (2.5, 1.2-5.4), and inversely correlated with a decreased level of consciousness (.3, .1-.8), and EC (.3, .1-.6) and basilar artery pathology (.1, .0-.6). Various clinical findings, cardiovascular risk factors, and arterial pathology on acute CTA-based imaging are moderately associated with spontaneous and post-thrombolytic arterial recanalization at 24 hours. If confirmed in other studies, this information may influence patient selection

We used Surveillance, Epidemiology, and End Results-Medicare data (2000-2006) to describe treatment and survival in women diagnosed with metastatic breast cancer (MBC) who received trastuzumab. There were 610 patients with a mean age of 74 years. Overall, 32% received trastuzumab alone and 47% received trastuzumab plus a taxane. In multivariate analysis, trastuzumab plus chemotherapy was associated with a lower adjusted cancer mortality rate (Hazard Ratio [HR] 0.54; 95% Confidence Interval [CI] 0.39-0.74; p < .001) than trastuzumab alone among patients who received trastuzumab as part of first-line therapy. Adding chemotherapy to first-line trastuzumab for metastatic breast cancer is associated with improved cancer survival. PMID:21929325

We investigated the major determinant of hyperphosphatemia incidence among patients receiving peritoneal dialysis. Seventy-six patients aged 25-55 years who had received peritoneal dialysis for more than 3 months were recruited. The patients were divided into three groups according to their serum phosphorus levels (Group 1, ≥ 6 mg/dL; Group 2, 5.9-4.8 mg/dL; and Group 3, <4.8 mg/dL). Renal dietitians interviewed the patients to determine their phosphate intake and adherence to phosphate binder therapy. No statistical differences in demographics or phosphate intake were identified among the groups. However, adherence to phosphate binders was greater in Group 3 than in Groups 1 and 2 (96.3% vs. 21.4% and 52.4%, respectively; P < 0.001). Multivariate analysis showed that adherence to phosphate binder therapy was the only significant contributor to serum phosphorus levels (P= 0.0001). Adherence to diet was better than adherence to phosphate binder therapy among patients receiving peritoneal dialysis, and the latter determined the incidence of hyperphosphatemia. © 2012 The Authors.

To evaluate protein C, protein S level in patients with diabetes mellitus receiving statin and ACE inhibitor/ARB therapy. 95 patients were included in the study and divided into four groups depending on the use of statin and ACE inhibitor/ARB therapy. Group 1 comprised of patients receiving statin therapy (n = 15), Group 2 comprised of patients receiving ACE inhibitor/ARB therapy (n = 31), Group 3 comprised of patients receiving statin and ACE inhibitor/ARB therapy (n = 23), and Group 4 comprised of patients who did not receive either statin or ACE inhibitor/ARB therapy (n = 26). These four groups were compared with respect to protein C, protein S, fibrinogen, D-dimer, INR, and aPTT levels. There were statistically significant differences with respect to protein C levels. Group 1 and group 2 had higher protein C levels compared with group 4. (p < .01). Similarly, Group 3 had higher protein C levels compared with group 4. (p < .01). There was no significant difference between the groups with respect to protein S, INR, aPTT, and D-dimer levels. Diabetic patients receiving statin or ACE inhibitor/ARB therapy had higher protein C levels. Use of statin and ACE inhibitor/ARB therapy in diabetic patients decrease hypercoagulability and therefore could reduce the occurrence of cardiovascular events. Copyright © 2017 Elsevier B.V.

PCR-based preemptive therapy with ganciclovir has been shown to reduce the incidence of CMV disease after BMT. Failures of this treatment strategy are CMV disease and secondary non-viral infections. Eighty-six consecutive patients at high risk for CMV disease who received PCR-based preemptive therapy with ganciclovir were assessed for treatment failures and possible risk factors. Ganciclovir was initiated in 57 of 86 patients (66%). Only 28 of 86 (32%) patients received 4 or more weeks of ganciclovir. Recurrence of CMV infection after successful treatment was more frequent among recipients of a BMT from an unrelated compared to a sibling donor (P = 0.004). Three (3.5%) patients developed non-fatal early onset CMV disease and seven of 68 (10.3 %) late onset CMV disease (>100 days post transplant). Risk factors for late onset CMV disease were cGVHD (P = 0.0017) and duration of prior antiviral therapy >4 weeks (P = 0. 0073). The incidence of secondary non-viral infections was 28% with the duration of antiviral treatment being a significant risk factor for secondary bacterial (P = 0.0045) and invasive fungal infections (P = 0.006). Thus, PCR-based preemptive treatment with ganciclovir reduces early onset CMV disease, but the duration of antiviral therapy prior to day +100 is a significant risk factor for late onset CMV disease as well as secondary non-viral infections.

Primary angioplasty: the past, the present and the future.

Primary angioplasty (PTCA) in acute myocardial infarction has many theoretical advantages including better antegrade flow and reduced intracranial haemorrhage. However the improvement in the mortality and morbidity of primary angioplasty in the randomized trials from sophisticated centres has not been translated to the community setting. Primary PTCA is a suitable alternative to thrombolytic therapy if performed in a timely fashion by persons skilled in the procedure in a suitable laboratory. It is also recommended in patients with cardiogenic shock and in those with contraindications to thrombolytic therapy. Combination of thrombolytics and glycoprotein IIb/IIIa inhibitors with primary angioplasty may form the reperfusion strategy of the future.

The accuracy of arterial blood pressure (ABP) monitoring is crucial in treating septic shock patients. Clinically significant differences in central to peripheral ABP could develop into sepsis during vasopressor therapy. The aim of this study was to investigate the difference between radial (peripheral) and femoral (central) ABP in septic shock patients receiving high-dose norepinephrine (NE) therapy. This prospective observational study comparing simultaneous intra-arterial measurements of radial and femoral ABP was performed at a university-affiliated, tertiary referral center between October 2008 and March 2009. Patients with septic shock who needed continuous blood pressure monitoring and high-dose NE therapy 0.1 µg/kg per minute or greater to maintain mean arterial pressure (MAP) of 65 mmHg or greater were included. Statistical analysis was conducted using the Bland-Altman method for comparison of repeated measures. In total, 250 sets of systolic, mean, and diastolic femoral and radial ABP were recorded at baseline and after NE titration. Arterial blood pressure readings from the radial artery were underestimated compared with those from the femoral artery. Overall bias (mean difference between simultaneous measurements) between radial and femoral MAP was +4.9 mmHg; however, during high-dose NE therapy, the bias increased to +6.2 mmHg (95% limits of agreement: -6.0 to +18.3 mmHg). Clinically significant radial-femoral MAP differences (MAP ≥5 mmHg) occurred in up to 62.2% of patients with high-dose NE therapy. Radial artery pressure frequently underestimates central pressure in septic shock patients receiving high-dose NE therapy. Femoral arterial pressure monitoring may be more appropriate when high-dose NE therapy is administered.

Limited data are available from the Australian setting regarding bleeding in patients with atrial fibrillation (AF) receiving antithrombotic therapy. We aimed to investigate the incidence of hospital admissions due to bleeding and factors associated with bleeding in patients with AF who received antithrombotic therapy. A retrospective cohort study was conducted involving all patients with AF admitted to the Royal Hobart Hospital, Tasmania, Australia, between January 2011 and July 2015. Bleeding rates were calculated per 100 patient-years (PY) of follow-up, and multivariable modelling was used to identify predictors of bleeding. Of 2202 patients receiving antithrombotic therapy, 113 presented to the hospital with a major or minor bleeding event. These patients were older, had higher stroke and bleeding risk scores and were more often treated with warfarin and multiple antithrombotic therapies than patients who did not experience bleeding. The combined incidence of major and minor bleeding was significantly higher in warfarin- versus direct-acting oral anticoagulants (DOAC)- and antiplatelet-treated patients (4.1 vs 3.0 vs 1.2 per 100 PY, respectively; p = 0.002). Similarly, the rate of major bleeding was higher in patients who received warfarin than in the DOAC and antiplatelet cohorts (2.4 vs 0.4 vs 0.6 per 100 PY, respectively; p = 0.001). In multivariate analysis, increasing age, prior bleeding, warfarin and multiple antithrombotic therapies were independently associated with bleeding. The overall rate of bleeding in this cohort was low relative to similar observational studies. The rate of major bleeding was higher in patients prescribed warfarin compared to DOACs, with a similar rate of major bleeding for DOACs and antiplatelet agents. Our findings suggest potential to strategies to reduce bleeding include using DOACs in preference to warfarin, and avoiding multiple antithrombotic therapies in patients with AF.

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 singlemore » 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

This report describes an open-label, nonrandomized, prospective evaluation of the effects of angiotensin-converting enzyme inhibitor and angiotensin receptor blocker therapy on patients who have Fabry disease and also received enzyme replacement therapy with agalsidase-beta, given at 1 mg/kg body wt every 2 wk. Previous placebo-controlled phase III and phase IV trials with agalsidase-beta demonstrated clearing of globotriaosylceramide from vascular endothelia but little effect on proteinuria or progressive loss of kidney function in patients with Fabry disease and severe chronic kidney disease marked by overt proteinuria and/or estimated GFR <60 ml/min per 1.73 m2. Angiotensin-converting enzyme inhibitor and/or angiotensin receptor blocker therapy is the standard of care for patients with proteinuric kidney diseases, but their use is challenging in patients with Fabry disease and low or low-normal baseline systemic BP. A group of patients with Fabry disease were treated with antiproteinuric therapy, in conjunction with agalsidase-beta; sustained reductions in proteinuria with stabilization of kidney function were achieved in a group of six patients who had severe Fabry nephropathy; the progression rate was -0.23 +/- 1.12 ml/min per 1.73 m2 per yr with 30 mo of follow-up.

Individualised prediction of outcomes can support clinical and shared decision making. This paper describes the building of such a model to predict outcomes with and without intravenous thrombolysis treatment following ischaemic stroke. A decision analytic model (DAM) was constructed to establish the likely balance of benefits and risks of treating acute ischaemic stroke with thrombolysis. Probability of independence, (modified Rankin score mRS ≤ 2), dependence (mRS 3 to 5) and death at three months post-stroke was based on a calibrated version of the Stroke-Thrombolytic Predictive Instrument using data from routinely treated stroke patients in the Safe Implementation of Treatments in Stroke (SITS-UK) registry. Predictions in untreated patients were validated using data from the Virtual International Stroke Trials Archive (VISTA). The probability of symptomatic intracerebral haemorrhage in treated patients was incorporated using a scoring model from Safe Implementation of Thrombolysis in Stroke-Monitoring Study (SITS-MOST) data. The model predicts probabilities of haemorrhage, death, independence and dependence at 3-months, with and without thrombolysis, as a function of 13 patient characteristics. Calibration (and inclusion of additional predictors) of the Stroke-Thrombolytic Predictive Instrument (S-TPI) addressed issues of under and over prediction. Validation with VISTA data confirmed that assumptions about treatment effect were just. The C-statistics for independence and death in treated patients in the DAM were 0.793 and 0.771 respectively, and 0.776 for independence in untreated patients from VISTA. We have produced a DAM that provides an estimation of the likely benefits and risks of thrombolysis for individual patients, which has subsequently been embedded in a computerised decision aid to support better decision-making and informed consent.

Prostate cancer remains a common disease that is frequently treated with multimodal therapy. The goal of this study was to assess the impact of treatment of the primary tumor on survival in men who go onto receive chemotherapy for prostate cancer. Using surveillance, epidemiology and end results (SEER)-Medicare data from 1992 to 2009, we identified a cohort of 1614 men who received chemotherapy for prostate cancer. Primary outcomes were prostate cancer-specific mortality (PCSM) and all-cause mortality (ACM). We compared survival among men who had previously undergone radical prostatectomy (RP), radiation therapy (RT), or neither of these therapies. Propensity score adjusted Cox proportional hazard models and weighted Kaplan-Meier curves were used to assess survival. Compared to men who received no local treatment, PCSM was lower for men who received RP ± RT (HR 0.65, p < 0.01) and for those who received RT only (HR 0.79, p < 0.05). Patients receiving neither RP nor RT demonstrated higher PCSM and ACM than those receiving treatment in a weighted time-to-event analysis. Men who received RP + RT had longer mean time from diagnosis to initiation of chemotherapy (100.7 ± 47.7 months) than men with no local treatment (48.8 ± 35.0 months, p < 0.05). In patients who go on to receive chemotherapy, treatment of the primary tumor for prostate cancer appears to confer a survival advantage over those who do not receive primary treatment. These data suggest continued importance for local treatment of prostate cancer, even in patients at high risk of failing local therapy.

Pain may be reported in one-half to three-fourths of children with cancer and other terminal conditions and anxiety in about one-third of them. Pharmacologic methods do not always give satisfactory symptom relief. Complementary therapies such as Reiki may help children manage symptoms. This pre-post mixed-methods single group pilot study examined feasibility, acceptability, and the outcomes of pain, anxiety, and relaxation using Reiki therapy with children receiving palliative care. A convenience sample of children ages 7 to 16 and their parents were recruited from a palliative care service. Two 24-minute Reiki sessions were completed at the children's home. Paired t tests or Wilcoxon signed-rank tests were calculated to compare change from pre to post for outcome variables. Significance was set at P < .10. Cohen d effect sizes were calculated. The final sample included 8 verbal and 8 nonverbal children, 16 mothers, and 1 nurse. All mean scores for outcome variables decreased from pre- to posttreatment for both sessions. Significant decreases for pain for treatment 1 in nonverbal children ( P = .063) and for respiratory rate for treatment 2 in verbal children ( P = .009). Cohen d effect sizes were medium to large for most outcome measures. Decreased mean scores for outcome measures indicate that Reiki therapy did decrease pain, anxiety, heart, and respiratory rates, but small sample size deterred statistical significance. This preliminary work suggests that complementary methods of treatment such as Reiki may be beneficial to support traditional methods to manage pain and anxiety in children receiving palliative care.

Beta-blockers are frequently prescribed to implantable cardioverter-defibrillator (ICD) patients. Beta-blocker therapy has been proposed to induce emotional distress such as depression and anxiety, but a paucity of studies has examined the relationship between beta-blockers and distress. We investigated the association between beta-blocker therapy, including type and dosage, and symptoms of anxiety and depression in a consecutive cohort of patients receiving an ICD. Between 2003 and 2010, 448 consecutively implanted ICD patients were enrolled in the prospective Mood and personality as precipitants of arrhythmia in patients with an Implantable cardioverter Defibrillator: A prospective Study (MIDAS), of which 429 completed the Hospital Anxiety and Depression Scale (HADS) and the ICD Patient Concerns questionnaire (ICDC) at baseline. Eighty per cent of all patients received beta-blocker therapy. In univariate analysis, beta-blocker therapy was not significantly associated with symptoms of anxiety, depression, and ICD concerns (β = -0.030, β = 0.007, and β = -0.045, respectively; all P's >0.36). Type of beta-blocker showed a trend towards significance for mean levels of ICD concerns (P = 0.09). No association was found between dosage and emotional distress (all P's >0.21). After adjustment for relevant clinical and demographic variables, the association of beta-blocker therapy and symptoms of anxiety, depression, and ICD concerns remained non-significant (β = 0.009, β = 0.037, and β = 0.019, respectively; all P's >0.47). In patients receiving an ICD, beta-blocker therapy was not associated with symptoms of anxiety, depression, and ICD concerns. Research is warranted that further elucidates the link between beta-blocker therapy and emotional distress in this vulnerable patient group.

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.

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.

The use of anti-programmed cell death (PD)-1 therapies in metastatic tumors is associated with cutaneous side effects including vitiligo-like lesions. We sought to characterize clinically and biologically vitiligo-like lesions occurring in patients receiving anti-PD-1 therapies by studying a case series of 8 patients with metastatic tumors and 30 control subjects with vitiligo. Eight patients receiving anti-PD-1 therapies with features of vitiligo-like lesions seen in our department were recruited. Clinical features and photographs were analyzed. For some patients, skin and blood samples were obtained. Results were compared with the vitiligo group. All patients developed lesions localized on photoexposed areas with a specific depigmentation pattern consisting of multiple flecked lesions without Koebner phenomenon. In contrast to vitiligo, patients receiving anti-PD-1 therapies who developed vitiligo-like lesions did not report any personal or family histories of vitiligo, thyroiditis, or other autoimmune disorders. Analysis of blood and skin samples revealed increased C-X-C motif ligand 10 levels in serum of patients developing vitiligo-like lesions, associated with skin infiltration of CD8 T-cells expressing C-X-C motif receptor 3 and producing elevated levels of interferon-γ and tumor necrosis factor-alfa. This cross-sectional study concerned a single center. Clinical and biological patterns of vitiligo-like lesions occurring in patients receiving anti-PD-1 therapies differ from vitiligo, suggesting a different mechanism.

To review the official international recommendations on the management of latent tuberculosis infection (LTBI) in patients with rheumatic diseases undergoing biologic therapy. A systematic search of all clinical practice recommendations on the diagnosis and treatment of LTBI in rheumatic patients eligible for starting biologic drugs published between January 2002 and March 2013. For the diagnosis of LTBI, based on positivity of tuberculin skin test (TST), interferon-γ release assay (IGRA) is also available. Most recommendations advise using both TST and IGRA, especially in case of Bacillus Calmette-Guérin vaccination, to screen patients before commencing biologic drugs. There is a general consensus that evaluation of the global risk of TB infection is a crucial point and that patients with LTBI must receive chemoprophylaxis prior to biologic therapy. However, recommendations on the need for rescreening for activation of LTBI or new TB infection while patients are being treated are inadequate. Nevertheless, the main concern is poor compliance with TB recommendations of rheumatologists in clinical practice, which seems to be the main cause of the occurrence of active TB in rheumatic patients receiving biologic therapy. Notwithstanding some differences, mainly related to regional TB incidence, international recommendations strongly suggest careful screening for LTBI before starting biologic therapy. However, the critical point is implementing dissemination and awareness of the recommendations among rheumatologists to improve adherence in real life.

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.

This exploratory case comparison examines the influence of case management activities on engagement and progress in psychotherapy for clients with schizophrenia. Six clients were recruited to participate in ten sessions of Cognitive Behavioral Therapy for psychosis (CBT-p). Three clients who had received Cognitive Behavioral techniques for psychosis (CBt-p, a low-intensity case management intervention) prior to receiving therapy were selected from referrals. A comparison group of three clients who had received standard case management services was selected from referrals. Cases within and across groups were compared on outcome measures and observations from case review were offered to inform future research. Delivering CBT-p services on a continuum from low- to high-intensity is discussed.

Introduction: The EvaluateTM study (Evaluation of therapy management and patient compliance in postmenopausal hormone receptor-positive breast cancer patients receiving letrozole treatment) is a prospective, non-interventional study for the assessment of therapy management and compliance in the routine care of postmenopausal women with invasive hormone receptor-positive breast cancer receiving letrozole. The parameters for inclusion in the study are presented and discussed here. Material and Methods: Between January 2008 and December 2009 a total of 5045 patients in 310 study centers were recruited to the EvaluateTM study. Inclusion criteria were hormone receptor-positive breast cancer and adjuvant treatment or metastasis. 373 patients were excluded from the analysis for various reasons. Results: A total of 4420 patients receiving adjuvant treatment and 252 patients with metastasis receiving palliative treatment were included in the study. For 4181 patients receiving adjuvant treatment, treatment with the aromatase inhibitor letrozole commenced immediately after surgery (upfront). Two hundred patients had initially received tamoxifen and started aromatase inhibitor treatment with letrozole at 1–5 years after diagnosis (switch), und 39 patients only commenced letrozole treatment 5–10 years after diagnosis (extended endocrine therapy). Patient and tumor characteristics were within expected ranges, as were comorbidities and concurrent medication. Conclusion: The data from the EvaluateTM study will offer a good overview of therapy management in the routine care of postmenopausal women with hormone receptor-positive breast cancer. Planned analyses will look at therapy compliance and patient satisfaction with how information is conveyed and the contents of the conveyed information. PMID:25568468

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.

The DRAGON score, which includes clinical and computed tomographic (CT) scan parameters, predicts functional outcomes in ischemic stroke patients treated with intravenous tissue plasminogen activator (IV tPA). We assessed the utility of the DRAGON score in predicting functional outcome in stroke patients receiving both IV tPA and endovascular therapy. A retrospective chart review of patients treated at our institution from February 2009 to October 2015 was conducted. All patients with computed tomography angiography (CTA) proven large vessel occlusions (LVO) who underwent intravenous thrombolysis and endovascular therapy were included. Baseline DRAGON scores and modified Rankin Score (mRS) at the time of hospital discharge was calculated. Good outcome was defined as mRS ≤3. Fifty-eight patients with LVO of the anterior circulation were studied. The mean DRAGON score of patients on admission was 5.3 (range, 3-8). All patients received IV tPA and endovascular therapy. Multivariate analysis demonstrated that DRAGON scores ≥7 was associated with higher mRS ( P < 0.006) and higher mortality ( P < 0.0001) compared with DRAGON scores ≤6. Patients with DRAGON scores of 7 and 8 on admission had a mortality rate of 3.8% and 40%, respectively. The DRAGON score can help predict better functional outcomes in ischemic stroke patients receiving both IV tPA and endovascular therapy. This data supports the use of the DRAGON score in selecting patients who could potentially benefit from more invasive therapies such as endovascular treatment. Larger prospective studies are warranted to further validate these results.

Is exercise training safe and beneficial in patients receiving left ventricular assist device therapy?

Because a limited number of patients receive heart transplantation, alternative therapies, such as left ventricular assist device (LVAD) therapy, have emerged. Published studies have shown that LVAD implantation, by itself, improves exercise tolerance to the point where it is comparable to those with mild heart failure. The improvement in exercise capacity is maximally achieved 12 weeks after LVAD therapy and can continue even after explantation of the device. This effect varies, depending on the type of LVAD and exercise training. The available data in the literature on safety and benefits of exercise training in patients after LVAD implantation are limited, but the data that are available suggest that training trends to be safe and have an impact on exercise capacity in LVAD patients. Although no studies were identified on the role of cardiac rehabilitation programs in the management of LVAD patients, it appears that cardiac rehabilitation programs offer an ideal setting for the provision of supervised exercise training in this patient group.

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 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 (relativemore » 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. 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 5 patients (2 pacemakers and 3 defibrillators). Five of these malfunctions were CIED resets, and 1 patient with a defibrillator (in a patient with a liver tumor) had an elective replacement indicator 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 elective replacement indicator 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

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.

We report a case of vein rupture by Arrow-Trerotola percutaneous thrombolytic device (Trerotola PTD) during a treatment of thrombosed arteriovenous graft (AVG). A 77-year-old woman with a problem of thrombosed AVG underwent an endovascular treatment including a procedure of angioplasty of axillary vein. After angioplasty of axillary vein, we found a newly developed thrombus in axillary vein and performed thrombolysis using an over-the-wire 7F Trerotola PTD. When the rotating cage of the device arrived at axillary vein, it suddenly stopped, fixed at the angioplasty site, and didn't move at all. Venogram showed an extravasation of contrast media at axillary vein, suggesting vein rupture. The patient underwent an emergency operation. It could be dangerous to use Trerotola PTD in a native vein immediately after angioplasty.

Dikken, Johan L.; Department of Surgery, Leiden University Medical Center, Leiden; Coit, Daniel G.

Purpose: The internationally validated Memorial Sloan-Kettering Cancer Center (MSKCC) gastric carcinoma nomogram was based on patients who underwent curative (R0) gastrectomy, without any other therapy. The purpose of the current study was to assess the performance of this gastric cancer nomogram in patients who received chemoradiation therapy after an R0 resection for gastric cancer. Methods and Materials: In a combined dataset of 76 patients from the Netherlands Cancer Institute (NKI), and 63 patients from MSKCC, who received postoperative chemoradiation therapy (CRT) after an R0 gastrectomy, the nomogram was validated by means of the concordance index (CI) and a calibration plot. Results:more » The concordance index for the nomogram was 0.64, which was lower than the CI of the nomogram for patients who received no adjuvant therapy (0.80). In the calibration plot, observed survival was approximately 20% higher than the nomogram-predicted survival for patients receiving postoperative CRT. Conclusions: The MSKCC gastric carcinoma nomogram significantly underpredicted survival for patients in the current study, suggesting an impact of postoperative CRT on survival in patients who underwent an R0 resection for gastric cancer, which has been demonstrated by randomized controlled trials. This analysis stresses the need for updating nomograms with the incorporation of multimodal strategies.« less

To elucidate the factors associated with residual gastroesophageal reflux disease (GERD) symptoms in patients receiving proton pump inhibitor (PPI) maintenance therapy in clinical practice. 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. 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). 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.

Purpose: Selection of patients with cerebral infarction for MRI that is suitable for thrombolytic therapy as an emerging application. Although the efficiency of the therapy with i.v. tissue plasminogen activator (tPA) within 3 hours after onset of symptoms has been proven in selected patients with CT, now these criteria are determined by MRI, as the data we gather are fast and accurate in the first hours. Material and methods: MRI screening in patients with acute cerebral infarction before application of thrombolytic therapy was done in a UCC Mannheim in Germany. Unlike trials with CT, MRI studies demonstrated the benefits of therapy up to 6 hours after the onset of symptoms. We studied 21 patients hospitalized in Clinic of Neuroradiology at University Clinical Centre in Mannheim-Germany. They all undergo brain MRI evaluation for stroke. This article reviews literature that has followed application of thrombolysis in patients with cerebral infarction based on MRI. Results: We have analyzed the MRI criteria for i.v. application of tPA at this University Centre. Alongside the personal viewpoints of clinicians, survey reveals a variety of clinical aspects and MRI features that are opened for further more exploration: therapeutic effects, the use of the MRI angiography, dynamics, and other. Conclusions: MRI is a tested imaging method for rapid evaluation of patients with hyperacute cerebral infarction, replacing the use of CT imaging and clinical features. MRI criteria for thrombolytic therapy are being applied in some cerebral vascular centres. In Kosovo, the application of thrombolytic therapy has not started yet. PMID:25729591

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.

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.

Transfusional iron overload in patients with chronic anemias can result in multiple organ failure. Experience in the management of iron overload in patients with myelodysplastic syndromes is limited, as many do not receive chelation therapy due to short-life expectancy and the difficulties associated with the administration of the current reference standard chelator, deferoxamine. There have, however, been some reports of reduced transfusion requirement associated with chelation therapy in patients with myelodysplastic syndromes and myelofibrosis. Here, we discuss a patient with primary myelofibrosis and related transfusion-dependent anemia who received chelation therapy with the once-daily oral iron chelator, deferasirox. In addition to the reduced iron levels, the patient demonstrated an unexpected reduction in blood transfusion requirement, ultimately resulting in long-lasting transfusion-free survival.

This study was carried out to evaluate the prognostic value of KIBRA in breast cancer. This retrospective study included breast cancer patients who sought the services of the immunohistochemistry laboratory of our unit from 2006 to 2015. Tissue microarrays were constructed and immunohistochemical staining was done to assess the KIBRA expression. The Kaplan-Meier model for univariate and Cox-regression model with backward stepwise factor retention method for multivariate analyses were used. Chi square test was used to find out the associations with the established prognostic features. A total of 1124 patients were included in the study and KIBRA staining of 909 breast cancers were available for analysis. Cytoplasmic KIBRA expression was seen in 39.5% and nuclear expression in 44.8%. Overall KIBRA-low breast cancers accounted for 41.5%. KIBRA nuclear expression was significantly associated with positive ER and PR expression. Luminal breast cancer patients who had endocrine therapy and KIBRA-low expression had a RFS disadvantage over those who were positive for KIBRA (p = 0.02). Similarly, patients who received chemotherapy and had overall KIBRA-low expression also demonstrated a RFS disadvantage compared to those who had overall positive KIBRA expression (p = 0.018). This effect of KIBRA was independent of the other factors considered for the model. Overall low-KIBRA expression has an independent effect on the RFS and predicts the RFS outcome of luminal breast cancer patients who received endocrine therapy and breast cancer patients who received chemotherapy.

The primary aim of thrombolysis in acute ischemic stroke is recanalization of an occluded intracranial artery. Recanalization is an important predictor of stroke outcome as timely restoration of regional cerebral perfusion helps salvage threatened ischemic tissue. At present, intravenously administered tissue plasminogen activator (IV-TPA) remains the only FDA-approved therapeutic agent for the treatment of ischemic stroke within 3 hours of symptom onset. Recent studies have demonstrated safety as well as efficacy of IV-TPA even in an extended therapeutic window. However, the short therapeutic window, low rates of recanalization, and only modest benefits with IV-TPA have prompted a quest for alternative approaches to restore blood flow in an occluded artery in acute ischemic stroke. Although intra-arterial delivery of the thrombolytic agent seems effective, various logistic constraints limit its routine use and as yet no lytic agent have not received full regulatory approval for intra-arterial therapy. Mechanical devices and approaches can achieve higher rates of recanalization but their safety and efficacy still need to be established in larger clinical trials. The field of acute revascularization is rapidly evolving, and various combinations of pharmacologic agents, mechanical devices, and novel microbubble/ultrasound technologies are being tested in multiple clinical trials.

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

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.

Measures of balance are an important component of the physical therapist examination. This study investigated the usefulness of timed static stance durations for identifying balance impairments among patients receiving home-based physical therapy. This study involved the retrospective retrieval of data from the records of 48 patients at least 60 years of age. Their balance was measured under 3 foot configurations; that is, feet apart, feet together, and on each foot. Every patient demonstrated impaired standing balance. Most, but not all could balance 30 seconds with the feet apart or together. Only 19 could maintain balance on each of both feet. Of those who could so balance, none was able to achieve the average time of normal individuals of comparable age. Although not able to identify all aspects of balance, timed durations of stance under different configurations demonstrate a high prevalence of balance impairments among patients receiving home-based physical therapy. As the tests are objective, fast, and require little space, they can be advocated in such a setting.

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 wasmore » 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.« less

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.

Numerous studies have found that the framing effect is common in medical scenarios, but few studies have examined the influence of the framing effect upon thrombolytic therapy for cerebral infarction. In this study, 1040 inpatients and outpatients in the department of neurology were recruited to explore whether there is a framing effect in decision-making within thrombolytic therapy, and if so, which factors influence that effect. The findings from Study 1 indicate that the framing effect occurred in patients both with and without cerebral infarction (χ(2) = 7.90, p = .005; χ(2) = 5.16, p = .023, respectively), with both groups displaying risk-seeking behavior (thrombolytic therapy) in the positive frame and no risk aversion or risk seeking in the negative frame. The results of Study 2 show that the patients preferred risk seeking in both collaborative and individual decision-making. In the collaborative decision-making group, the patients in the senior group showed the framing effect (χ(2) = 5.35, p < .05), with the patients in the positive frame (G) showing more significant risk seeking than both those in the negative frame (H) and those in the other positive frame (A, C, and E). In summary, decision-making about thrombolytic therapy in patients with cerebral infarction is influenced by the framing effect, and some influencing factors should be attended in clinical practice. Further research is necessary to guide the treatment of cerebral infarction.

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.

There is a need to remove excess iron with iron chelation therapy (ICT) to avoid the serious clinical sequelae associated with iron overload in patients with beta thalassemia major (BTM) and sickle cell anemia (SCA). Due to the effects of the diseases and their treatments, ICT is still a major reason for unsatisfactory compliance. The aim of this single-center observational study was to evaluate the quality of life, clinical effectiveness, and satisfaction in pediatric and adult patients with BTM and SCA receiving deferasirox (DFX) chelation therapy. In this study, 37 pediatric and 35 adult patients with BTM or SCA receiving DFX for at least 6 months participated. Upon receipt of Informed Consent Form, Case Report Form, Demographic Data Collection Form, Child Health Questionnaire-Parent Form, Life Quality Survey Short Form-36, and ICT Satisfaction Survey were used to obtain data for the effectiveness of ICT and parameters that may affect compliance to treatment and life quality of the participants. As a main index for the effectiveness of DFX chelation therapy, serum ferritin levels were higher than the normal values in the patients receiving DFX. The increased ferritin levels were also associated with hematological and biochemical abnormalities. Our findings regarding quality of life and satisfaction with DFX chelation therapy indicated that the patients with BTM or SCA had lower scores. Overall, problems with treatment regimen and side effects appeared to be common causes of poor compliance to DFX chelation therapy. Our findings suggest that health care providers should be aware of the importance of monitoring iron load with timely initiation of DFX chelation therapy and ongoing adjustments to chelation regimens and/or transfusion methods to decrease hospitalizations and improve compliance to ICT of the patients with BTM and SCA.

To evaluate how accurately final infarct volume in acute ischemic stroke can be predicted with perfusion CT (PCT) using a 64-MDCT unit and the toggling table technique. Retrospective analysis of 89 patients with acute ischemic stroke who underwent CCT, CT angiography (CTA) and PCT using the "toggling table" technique within the first three hours after symptom onset. In patients with successful thrombolytic therapy (n = 48) and in those without effective thrombolytic therapy (n = 41), the infarct volume and the volume of the penumbra on PCT were compared to the infarct size on follow-up images (CT or MRI) performed within 8 days. The feasibility of complete infarct volume prediction by 8 cm cranio-caudal coverage was evaluated. The correlation between the volume of hypoperfusion on PCT defined by cerebral blood volume reduction and final infarct volume was strongest in patients with successful thrombolytic therapy with underestimation of the definite infarct volume by 8.5 ml on average. The CBV map had the greatest prognostic value. In patients without successful thrombolytic therapy, the final infarct volume was overestimated by 12.1 ml compared to the MTT map on PCT. All infarcts were detected completely. There were no false-positive or false-negative results. Using PCT and the "toggling table" technique in acute stroke patients is helpful for the rapid and accurate quantification of the minimal final infarct and is therefore a prognostic parameter which has to be evaluated in further studies to assess its impact on therapeutic decision. ▶ Using PCT and the “toggling table technique” allows accurate quantification of the infarct core and penumbra. ▶ It is possible to record dynamic perfusion parameters quickly and easily of almost the entire supratentorial brain volume on a 64-slice MDCT unit. ▶ The technique allows identification of those patients who could profit from thrombolytic therapy outside the established time intervals. © Georg Thieme Verlag

Ciclosporin is a calcineurin inhibitor that is currently registered for the treatment of canine atopic dermatitis. The most common adverse effects include mild, transient gastrointestinal disturbances. Single case reports of opportunistic infections due to Nocardia spp., Neospora spp. and papillomaviruses have also been reported. Clinicians should be aware of the potential risk of systemic immunosuppression and subsequent infection with Nocardia spp. in dogs receiving ciclosporin. Cutaneous nocardiosis in two dogs receiving ciclosporin therapy for management of canine atopic dermatitis. Histopathology, PCR for Nocardia spp. and computed tomography. One dog developed disseminated nocardiosis due to Nocardia brasiliensis and a second dog developed localized cutaneous nocardiosis due to a novel Nocardia species subsequent to ciclosporin administration at the recommended dose rate for the management of canine atopic dermatitis. The second case was receiving a combination of ciclosporin and ketoconazole, and serum trough ciclosporin levels were elevated. Clinicians should be aware of the potential risk of systemic immunosuppression and subsequent infection with Nocardia spp. in dogs receiving ciclosporin. Measurement of serum ciclosporin levels may be useful in identifying those individuals which are at risk of opportunistic infections. © 2013 ESVD and ACVD.

Purpose. To determine whether self-expanding plastic stent (SEPS) placement significantly improves quality of life and maintains optimal nutrition while allowing full-dose neoadjuvant therapy (NAT) in patients with esophageal cancer. Patients and Methods. A prospective, dual-institution, single-arm, phase II (http://ClinicalTrials.gov: NCT00727376) evaluation of esophageal cancer patients undergoing NAT prior to resection. All patients had a self-expanding polymer stent placed prior to NAT. The European Organisation for Research and Treatment of Cancer QLQ-C30 and QLQ-OG25, Functional Assessment of Cancer Therapy–Anorexia, and Functional Assessment of Cancer Therapy–General surveys were administered prior to stenting, within 1 week post-stent placement, and at the completion of neoadjuvant therapy. Results. Fifty-two patients were enrolled; 3 (5.8%) had stent migrations requiring replacement. There were no instances of esophageal erosion or perforation. All patients received some form of neoadjuvant therapy. Thirty-six (69%) received chemoradiation; 34 (93%) of these patients received the planned dose of chemotherapy, and 27 (75%) received the full planned dose of radiotherapy. There were 16 (31%) patients receiving chemotherapy alone; 12 (74%) of patients in the chemotherapy-alone group completed the planned dose of therapy. Conclusion. Placement of SEPS appears to provide significant improvement in quality of life related to dysphagia and eating restriction in patients with esophageal cancer undergoing neoadjuvant therapy. Consideration of SEPS instead of percutaneous feeding tube should be initiated as a first line in dysphagia palliation and NAT nutritional support. PMID:24567281

We sought explore the relative benefits of unfractionated heparin (UFH) compared with enoxaparin, alone or in combination with clopidogrel, in ST-segment elevation myocardial infarction (STEMI) patients not undergoing reperfusion therapy. This is a propensity score study from The International Survey on Acute Coronary Syndromes in Transition Countries (ISACS-TC/NCT01218776) on patients admitted between October 2010-June 2013. There were a total of 1175 STEMI patients who did not receive mechanical or pharmacological reperfusion. Of these, 1063 were eligible for the aim of the study, being treated with UFH (522/1175; 44.4%) or enoxaparin (541/1175; 46%). Clopidogrel in combination with UFH or enoxaparin was given to 751 (63.9%) patients. The primary endpoint was in-hospital mortality. Secondary endpoints were intracranial hemorrhages, and clinically relevant bleedings. After adjustment for any confounders, UFH was associated with a lower risk of in-hospital mortality in clopidogrel users (multivariate adjusted regression analysis: odds ratio [OR]: 0.62, 95% Confidence Interval [CI] 0.41-0.94) as compared with clopidogrel non-users (OR: 0.94, 95% CI 0.55-1.60). The observed effect was not associated with combined enoxaparin and clopidogrel therapy. Major bleeding events were comparable in the enoxaparin group and UFH group (0.4% and 1.5% respectively, p = 0.06). The risk of major hemorrhage was nearly similar with combined UFH-clopidogrel therapy (1.4%) as compared with UFH alone (1.9%), p = 0.67. UFH - Clopidogrel combination was associated with a large mortality reduction in STEMI patients not undergoing reperfusion therapy and did not significantly increase the risk of major bleeding.

The purpose of the present study was to identify variables relevant to psychological well-being in HIV patients receiving highly active antiretroviral therapy (HAART). Multiple stressors accompany living with HIV while managing a HAART regimen. However, a variety of cognitive and behavioral variables can protect against or augment the deleterious effects of stress in this population. The authors hypothesized that satisfaction with social support, coping styles, and maladaptive attributions about HIV would explain more variance in psychological well-being than stressful life events per se. Participants were individuals with HIV receiving antiretroviral therapy-either starting a new HAART regimen or having difficulties adhering to their current regimen. Satisfaction with social support, coping styles, and punishment beliefs about HIV were uniquely associated with depression, quality of life, and self-esteem over and above the effects of stressful life events. These results provide support for continued psychosocial interventions that target these variables among patients with HIV.

Massage therapy has been consistently shown to increase weight gain in preterm infants. The mechanism of this presumed improved metabolic efficiency is unknown. We conducted the following trial to test the hypothesis that massage therapy reduces energy expenditure in growing healthy preterm infants. A prospective, randomized, cross-over design study was conducted in 10 healthy, appropriate weights for gestational age, gavage fed preterm infants. Each infant was studied twice: after a period of either 5 days of massage therapy, or after a period of 5 days without massage therapy. Infants were randomized to 5 days of massage followed by 5 days of no massage (n = 5) or the opposite sequence (n = 5). During the massage therapy period, massage was provided daily for three 15 minute periods at the beginning of each 3 hour period every morning. Metabolic measurements were performed by indirect calorimetry, using the Deltatrac II Metabolic cart. Energy expenditure was significantly lower in infants after the 5 day massage therapy period (59.6 +/- 3.6 Kcal/Kg/ 24 hours) than after the period without (63.1 +/- 5.4 Kcal/Kg/ 24 hours) (p = 0.05). Energy expenditure is significantly lowered by 5 days of massage therapy in metabolically and thermally stable preterm infants. This decrease in energy expenditure may be in part responsible for the enhanced growth caused by massage therapy.

Predictors of receiving therapy among very low birth weight 2-year olds eligible for Part C early intervention in Wisconsin

PubMed Central

2013-01-01

Background 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. Methods 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. Results 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). Conclusions 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. PMID:23845161

The consequences of a supplemented very-low-protein diet remain a matter of debate with regard to patient outcome before or after the onset of renal replacement therapy. We evaluated the long-term clinical outcome during maintenance dialysis and/or transplantation in patients who previously received a supplemented very-low-protein diet. We assessed the outcome of 203 patients who received a supplemented very-low-protein diet for >3 mo (inclusion period: 1985-2000) and started dialysis after a mean diet duration of 33.1 mo (4-230 mo). The survival rate in the whole cohort was 79% and 63% at 5 and 10 y, respectively. One hundred two patients continued with chronic dialysis during the entire follow-up, and 101 patients were grafted at least once. Patient outcomes were similar to those of the French Dialysis Registry patients for the dialysis group and similar to the 865 patients who were transplanted in Bordeaux during the same period for the transplant group. There was no correlation between death rate and duration of diet. The lack of correlation between death rate and duration of diet and the moderate mortality rate observed during the first 10 y of renal replacement therapy confirm that a supplemented very-low-protein diet has no detrimental effect on the outcome of patients with chronic kidney disease who receive renal replacement therapy.

For organ transplant recipients, cancer secondary to immunosuppressive therapy threatens long-term survival. The associated multiple comorbidities make major free flap reconstruction following cancer surgery a complicated event. This study evaluates the outcomes of free flap reconstruction in this population. A retrospective chart review of all head and neck free flap cases in patients with a history of organ transplantation receiving systemic immunosuppressive therapy between 2005 and 2017 at a single-institution was conducted. Of 57 organ transplant patients, 25 patients (28 flaps) were included. Flaps used included the anterolateral thigh (n = 17), radial forearm (n = 4), latissimus dorsi (n = 3), fibula (n = 2), lateral arm (n = 1), and thoracodorsal artery perforator (n = 1) flaps. The most common organ transplant was kidney, then lung, liver, and heart. Mean inpatient stay was 8.2 days (range, 4-28). Complications occurred in 15 patients, with no total or partial flap losses. Major head and neck free flap reconstructive surgery can be performed safely in organ transplant patients receiving immunosuppressive therapy. Meticulous multidisciplinary care is required to achieve consistently successful outcomes. © 2018 Wiley Periodicals, Inc.

To assess eating behavior and nutrient intake in a group of patients who were diagnosed with chronic pain and received long-term opioid analgesic therapy. A descriptive, exploratory study with a convenience sample. An outpatient pain rehabilitation center. Patients diagnosed with chronic pain who received long-term opioid analgesic therapy (N = 50). Body mass index, the Food Frequency Questionnaire developed by the Nutrition Assessment Shared Resource of Fred Hutchinson Cancer Research Center, and the Eating Behavior Inventory. Of 50 participants, 14 (28%) and 22 (44%) were found to be overweight and obese, respectively. Mean (±SD) daily caloric intake (kcal) was 2008.5 ± 926.0 among men and 1694.8 ± 672.4 among women. Daily mean (±SD) consumption of fruit and vegetable servings, calculated with the summation method, was found to be 1.8 ± 1.1 and 1.9 ± 1.5, respectively. Our patient sample showed the following mean (±SD) daily intake of the following substances: added sugars (g), 74.4 ± 43.0; fiber (g), 17.3 ± 7.5; cholesterol (mg), 266.5 ± 234; saturated fat (g), 25.8 ± 16.8; omega-3 fatty acids (g), 1.6 ± 0.99; trans-fatty acids (g), 2.7 ± 1.7; sodium (mg), 2868.5 ± 1388.1; caffeine (mg), 199.9 ± 160.8; alcohol (g), 1.6 ± 0.5; vitamin D (IU), 244 ± 208; and calcium (mg), 1111.7 ± 672.1. The mean (±SD) score as calculated by the Eating Behavior Inventory was 74.9 ± 9.1. Obesity, deficient nutrient intake, and poor eating behavior were highly prevalent in our sample of patients with chronic pain who underwent long-term opioid therapy. Larger prospective studies are necessary to assess the eating behavior of patients with chronic pain who are treated with or without opioid analgesics.

Computed tomography (CT) is the current standard for time-critical decision-making in stroke patients, informing decisions on thrombolytic therapy with tissue plasminogen activator (tPA), which has a narrow therapeutic index. We aimed to develop a CT-based method to directly visualize cerebrovascular thrombi and guide thrombolytic therapy. Glycol-chitosan-coated gold nanoparticles (GC-AuNPs) were synthesized and conjugated to fibrin-targeting peptides, forming fib-GC-AuNP. This targeted imaging agent and non-targeted control agent were characterized in vitro and in vivo in C57Bl/6 mice (n = 107) with FeCl3-induced carotid thrombosis and/or embolic ischemic stroke. Fibrin-binding capacity was superior with fib-GC-AuNPs compared to GC-AuNPs, with thrombi visualized as high density on microCT (mCT). mCT imaging using fib-GC-AuNP allowed the prompt detection and quantification of cerebral thrombi, and monitoring of tPA-mediated thrombolytic effect, which reflected histological stroke outcome. Furthermore, recurrent thrombosis could be diagnosed by mCT without further nanoparticle administration for up to 3 weeks. fib-GC-AuNP-based direct cerebral thrombus imaging greatly enhance the value and information obtainable by regular CT, has multiple uses in basic / translational vascular research, and will likely allow personalized thrombolytic therapy in clinic by a) optimizing tPA-dosing to match thrombus burden, b) enabling the rational triage of patients to more radical therapies such as endovascular clot-retrieval, and c) potentially serving as a theranostic platform for targeted delivery of concurrent thrombolysis.

Background: This article addresses the treatment of VTE disease. Methods: We generated strong (Grade 1) and weak (Grade 2) recommendations based on high-quality (Grade A), moderate-quality (Grade B), and low-quality (Grade C) evidence. Results: For acute DVT or pulmonary embolism (PE), we recommend initial parenteral anticoagulant therapy (Grade 1B) or anticoagulation with rivaroxaban. We suggest low-molecular-weight heparin (LMWH) or fondaparinux over IV unfractionated heparin (Grade 2C) or subcutaneous unfractionated heparin (Grade 2B). We suggest thrombolytic therapy for PE with hypotension (Grade 2C). For proximal DVT or PE, we recommend treatment of 3 months over shorter periods (Grade 1B). For a first proximal DVT or PE that is provoked by surgery or by a nonsurgical transient risk factor, we recommend 3 months of therapy (Grade 1B; Grade 2B if provoked by a nonsurgical risk factor and low or moderate bleeding risk); that is unprovoked, we suggest extended therapy if bleeding risk is low or moderate (Grade 2B) and recommend 3 months of therapy if bleeding risk is high (Grade 1B); and that is associated with active cancer, we recommend extended therapy (Grade 1B; Grade 2B if high bleeding risk) and suggest LMWH over vitamin K antagonists (Grade 2B). We suggest vitamin K antagonists or LMWH over dabigatran or rivaroxaban (Grade 2B). We suggest compression stockings to prevent the postthrombotic syndrome (Grade 2B). For extensive superficial vein thrombosis, we suggest prophylactic-dose fondaparinux or LMWH over no anticoagulation (Grade 2B), and suggest fondaparinux over LMWH (Grade 2C). Conclusion: Strong recommendations apply to most patients, whereas weak recommendations are sensitive to differences among patients, including their preferences. PMID:22315268

Prognostic biomarkers for patients with clear cell renal cell carcinoma (ccRCC), particularly those receiving therapy targeting angiogenesis, are not well established. In this study, we examined the correlations of monocarboxylate transporter 1 (MCT1) and MCT4, 2 critical transporters for glycolytic metabolism, with various clinicopathological parameters as well as survival of patients with ccRCC and those treated with vascular endothelial growth factor receptor (VEGFR) inhibitors. A cohort of 150 ccRCC patients were recruited into this study. All patients underwent radical or partial nephrectomy as the first-line treatment, and 38 received targeted therapy (sorafenib or sunitinib) after the surgery. Expression levels of MCT1, MCT4, and CD34 were examined by immunohistochemistry. Correlations between MCT1 or MCT4 expression and different clinicopathological parameters or patient survival were analyzed among all as well as patients receiving targeted therapy. MCT1 or MCT4 expression did not significantly correlate with sex, age, tumor diameter, microvascular density, tumor staging, pathological Furmann grade, or MSKCC (P>0.05). High expression of either MCT1 or MCT4 significantly correlated with reduced overall survival (OS) and progression-free survival (PFS) among the total cohort of ccRCC patients. For patients receiving targeted therapy, high expression of either MCT1 or MCT4 significantly correlated with reduced PFS, but not OS. Both conditions were independent prognostic biomarkers for reduced PFS among all patients or those receiving targeted therapy. MCT1 and MCT4 are prognostic biomarkers for patients with ccRCC or those receiving targeted therapy. High expression of these 2 proteins predicts reduced PFS in these patients.

The consequences of stroke must be assessed not only in terms of incidence and mortality rates, but also in terms of disability, which may persist long after the acute phase. Thrombolysis, if timely administered, can effectively reduce post-stroke disability. The economic model presented herein aims to evaluate, in eligible patients, the effects of alteplase on post-stroke disability and related costs over three-years. The economic analysis was developed on the basis of four key components: clinical outcomes from international trials, economic consequences extracted from cost of illness studies, regulatory data from national and international agencies, and national epidemiological data. A population-level model estimated the difference in disability costs between patients treated with standard care versus those receiving thrombolytic therapy within 4×5 h of acute ischemic stroke. The analysis covered 36 months from discharge. Reduced costs related to post-stroke disability were observed in treated patients compared with those receiving standard care (control). The overall savings were €2330×15 per average patient: €1445×81 during the first 18 months, €362×25 between 18 and 24 months, and €522×09 in the 24-36 months period. The overall savings on 3174 Italian treated patients in 2013 were €7 395 907 over three-years. Our study reveals that performing thrombolytic therapy in eligible patients improves economic outcomes compared with patients receiving standard care. This model is useful for decision makers, both within and outside of the Italian national context, as a tool to assess the cost-effectiveness of thrombolysis in both short- and long-term period. © 2015 World Stroke Organization.

In metastatic prostate cancer patients PSMA targeting radioligands have gained significant impact as theranostic probes. In this study a correlation between total tumor volume (TTV) and measured kidney dose as well as salivary glands (SG) uptake in 177 Lu-PSMA-617 therapy was evaluated. Eleven consecutive prostate cancer patients receiving a first cylcle of 177 Lu-PSMA-617 (administered activity of approximately 6GBq) were included. The 68 Ga-PSMA-11 PET/CT scan previous to therapy was used to determine TTV and SG uptake (glandulae submandibularis) employing PMOD version 3.403 with different 68 Ga-PSMA-11 thresholds based on the standardized uptake value (SUV).The kidney dose was estimated with the software ULMDOS using planar whole-body scintigrams. Kidney dose and SG uptake was inversely correlated to TTV, indicating high kidney dose and high SG uptake in case of low tumor load and low kidney dose and low SG uptake in case of high tumor load. Our data support the hypothesis that in 177 Lu-PSMA-617 therapy an individualized treatment activity based on total tumor volume could be beneficiary. Schattauer GmbH.

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 bymore » 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.« less

In recent years, the treatment landscape in advanced non-squamous non-small-cell lung cancer (nsNSCLC) has changed. New therapies (e.g., bevacizumab indicated in first line) have become available and other therapies (e.g., pemetrexed in first line and second line) moved into earlier lines in the treatment paradigm. While there has been an expansion of the available treatment options, it is still a key research question which therapy sequence results in the best survival outcomes for patients with nsNSCLC. A therapy-sequencing disease model that approximates treatment outcomes in up to five lines of treatment was developed for patients with nsNSCLC. The primary source of data for progression-free survival (PFS) and time to death was published pivotal trial data. All patients were treatment-naïve and in the PFS state, received first-line treatment with either bevacizumab-based therapy or doublet chemotherapy (including the option of pemetrexed + cisplatin). Patients would then progress to a subsequent line of therapy, remain in PFS or die. In case of progression, it was assumed that each survivor would receive a subsequent line of therapy, based on EMA licensed therapies. Weibull distribution curves were fitted to the data. All bevacizumab-based first-line therapy sequences analyzed achieved total PFS of around 15 months. Bevacizumab + carboplatin + paclitaxel (first line) → pemetrexed (second line) → erlotinib (third line) → docetaxel (fourth line) resulted in total mean PFS time of 15.7 months, for instance. Sequences with pemetrexed in combination with cisplatin in first line achieved total PFS times between 12.6 and 12.8 months with a slightly higher total PFS time achieved when assuming pemetrexed continuation therapy in maintenance after pemetrexed + cisplatin in first-line induction. Overall survival results followed the same trend as PFS. The model suggests that treatment-sequencing strategies starting with a bevacizumab-based combination in first line

Primary immunodeficiencies (PIDs) are inherited disorders in which one or several components of the immune system are defective. Immunoglobulin replacement therapy is the mainstay of treatment for patients with impaired antibody production. However, recurrent infections would continue to occur in some patients due to the other high frequent concomitant defects, such as mannose-binding lectin (MBL) deficiency. A total of 51 PID patients participated in this cross-sectional study. A detailed questionnaire was completed by interviewing patients in order to record demographic, clinical and laboratory data. The levels of MBL were determined in the serums of patients by a sandwich enzyme-linked immunosorbent assay (ELISA) technique. MBL deficiency was found in 29.4% of cases; 11.8% patients had mild, 3.9% patients had moderate and 13.7% patients had severe MBL deficiency. In patients with MBL deficiency, the rate of meningitis, sepsis, pneumonia, and otitis media was higher than patients with normal MBL levels. Immunoglobulin replacement therapy reduced the rate of infectious complications in PID patients; however, these reductions were more apparent in patients with normal MBL levels than patients with MBL deficiency. Antibody deficient patients with a concomitant immune defect in MBL production have higher rates of recurrent infections despite receiving Immunoglobulin replacement therapy.

Purpose: To assess the value of mid-therapy positron emission tomography (PET) findings for predicting survival and disease progression in patients with diffuse large B-cell lymphoma, considering type of therapy (chemotherapy with or without radiation therapy). Methods and Materials: We retrospectively evaluated 294 patients with histologically confirmed diffuse large B-cell lymphoma with respect to age, sex, disease stage, International Prognostic Index score, mid-therapy PET findings (positive or negative), and disease status after therapy and at last follow-up. Overall survival (OS) and progression-free survival (PFS) were compared according to mid-therapy PET findings. Results: Of the 294 patients, 163 (55%) were male, 144more » (49%) were age >61 years, 110 (37%) had stage I or II disease, 219 (74%) had International Prognostic Index score ≤2, 216 (73%) received ≥6 cycles of rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone, and 88 (30%) received consolidation radiation therapy. Five-year PFS and OS rates were associated with mid-therapy PET status: PFS was 78% for those with PET-negative (PET−) disease versus 63% for PET-positive (PET+) disease (P=.024), and OS was 82% for PET− versus 62% for PET+ (P<.002). These associations held true for patients who received chemotherapy only (PFS 71% for PET− vs 52% PET+ [P=.012], OS 78% for PET− and 51% for PET+ [P=.0055]) but not for those who received consolidation radiation therapy (PFS 84% PET− vs 81% PET+ [P=.88]; OS 90% PET− vs 81% PET+ [P=.39]). Conclusion: Mid-therapy PET can predict patient outcome, but the use of consolidation radiation therapy may negate the significance of mid-therapy findings.« less

Patients might refuse the offer of local anaesthesia (LA) administration prior to dental treatment. This study investigates subjective discomfort perception during non-surgical mechanical periodontal therapy delivered with or without LA. Sixty patients with mild to moderate chronic periodontitis and prior periodontal debridement experience were randomly enrolled in nonsurgical therapy of a quadrant with or without LA administration. Patients were free to comply or not with the allocated LA arrangement. Visual analogue scales (VAS) of discomfort perception at various stages of the treatment as well as overall satisfaction were recorded. Demographic, psychosocial and periodontal parameters were recorded. Thirty-one patients undergoing nonsurgical periodontal therapy not receiving (LA-) and 29 participants receiving LA (LA+) were studied. Compared to LA- patients, LA+ individuals perceived less discomfort during treatment and reported less dental anxiety (p<0.05). Lower overall treatment satisfaction was associated with prior unpleasant periodontal experience (p=0.047). Overall, debridement discomfort was associated with not receiving LA, noncompliance with the pain control regimen allocated, longer treatment duration, greater gingival inflammation and a higher percentage sites with probing pocket depths≥5 mm (p<0.05). Clinicians should be aware that patients who refuse LA can experience higher dental anxiety and therefore may require various pain control strategies for comfort during nonsurgical periodontal therapy, which, if not employed, can lead to less periodontal treatment satisfaction.

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

This study compares outcomes for behaviorally troubled children receiving intensive in-home therapy (IIHT) and those receiving residential care (RC). Propensity score matching is used to identify matched pairs of youth (n = 786) with equivalent propensity for IIHT. The majority of pretreatment differences between the IIHT and RC groups are eliminated following matching. Logistic regression is then conducted on outcome differences at 1 year postdischarge. Results show that IIHT recipients had a greater tendency (.615) toward living with family, making progress in school, not experiencing trouble with the law, and placement stability compared with RC youth (.558; p < .10). This suggests that IIHT is at least as effective for achieving positive outcomes. Given IIHT's reduced restrictiveness and cost, intensive in-home services should be the preferred treatment over RC in most cases.

To describe School Function Assessment (SFA) outcomes after 6 months of school-based physical therapy and the effects of age and gross motor function on outcomes. Within 28 states, 109 physical therapists and 296 of their students with disabilities, ages 5 to 12 years, participated. After training, therapists completed 10 SFA scales on students near the beginning and end of the school year. Criterion scores for many students remained stable (46%-59%) or improved (37%-51%) with the most students improving in Participation and Maintaining/Changing Positions. Students aged 5 to 7 years showed greater change than 8- to 12-year-olds on 5 scales. Students with higher gross motor function (Gross Motor Function Classification System levels I vs IV/V and II/III vs IV/V) showed greater change on 9 scales. Positive SFA change was recorded in students receiving school-based physical therapy; however, the SFA is less sensitive for older students and those with lower functional movement.

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.

Objective: To report late toxicity outcomes from a randomized trial comparing conventional and hypofractionated prostate radiation therapy and to identify dosimetric and clinical parameters associated with late toxicity after hypofractionated treatment. Methods and Materials: Men with localized prostate cancer were enrolled in a trial that randomized men to either conventionally fractionated intensity modulated radiation therapy (CIMRT, 75.6 Gy in 1.8-Gy fractions) or to dose-escalated hypofractionated IMRT (HIMRT, 72 Gy in 2.4-Gy fractions). Late (≥90 days after completion of radiation therapy) genitourinary (GU) and gastrointestinal (GI) toxicity were prospectively evaluated and scored according to modified Radiation Therapy Oncology Group criteria. Results: 101 men receivedmore » CIMRT and 102 men received HIMRT. The median age was 68, and the median follow-up time was 6.0 years. Twenty-eight percent had low-risk, 71% had intermediate-risk, and 1% had high-risk disease. There was no difference in late GU toxicity in men treated with CIMRT and HIMRT. The actuarial 5-year grade ≥2 GU toxicity was 16.5% after CIMRT and 15.8% after HIMRT (P=.97). There was a nonsignificant numeric increase in late GI toxicity in men treated with HIMRT compared with men treated with CIMRT. The actuarial 5-year grade ≥2 GI toxicity was 5.1% after CIMRT and 10.0% after HIMRT (P=.11). In men receiving HIMRT, the proportion of rectum receiving 36.9 Gy, 46.2 Gy, 64.6 Gy, and 73.9 Gy was associated with the development of late GI toxicity (P<.05). The 5-year actuarial grade ≥2 GI toxicity was 27.3% in men with R64.6Gy ≥ 20% but only 6.0% in men with R64.6Gy < 20% (P=.016). Conclusions: Dose-escalated IMRT using a moderate hypofractionation regimen (72 Gy in 2.4-Gy fractions) can be delivered safely with limited grade 2 or 3 late toxicity. Minimizing the proportion of rectum that receives moderate and high dose decreases the risk of late rectal toxicity after this

No specific instrument has been developed for measuring alliance during music therapy. To evaluate the feasibility of using the Helping Alliance Questionnaire II (HAq-II) as a self-report measure for individuals receiving treatment for a psychiatric disorder. Specifically, we examined the percent of patients who filled out the questionnaire, and when completed, whether there were any missing items. We also examined internal consistency and associations between patient variables and HAq-II scores. Between October 2013 and April 2014, we invited 45 individuals with a psychiatric disorder, who were also receiving music therapy, to fill out the HAq-II. We also collected clinical data from each person's record. Thirty-one (69%) of the 45 invited patients filled out the HAq-II, and of those completed, only three had missing items. Of the 45 invited patients, thirty (67%) had a diagnosis of schizophrenia or other psychotic disorders, and 11 (24%) were diagnosed with other psychiatric disorders. In terms of diagnosis and other clinical variables, no statistically significant differences were found between the 31 patients who filled out the HAq-II and the 14 patients who did not return the questionnaire. The median HAq-II score was 5.11 (range 3.74-6.00), indicating a relatively high alliance. We did not find any statistically significant associations between the HAq-II scores and potential predictors of interest. The Cronbach's alpha was 0.85. Completion of the HAq-II was fairly high in this group of individuals with psychiatric diagnoses who were receiving music therapy. Internal consistency of the HAq-II was acceptable. Relatively high HAq-II scores suggest a high degree of therapeutic alliance, but the external validity of the HAq-II and the relationship between scores and therapy needs further evaluation. © the American Music Therapy Association 2017.

In a previous pilot study, adrenal suppression was found to be common after antiemetic dexamethasone therapy in cancer patients. The objective of this large prospective multicenter study was to confirm the incidence and factors associated with secondary adrenal suppression related to antiemetic dexamethasone therapy in cancer patients receiving chemotherapy. Chemotherapy-naïve patients who were scheduled to receive at least three cycles of highly or moderately emetogenic chemotherapy with dexamethasone as an antiemetic were enrolled. Patients with a suppressed adrenal response before chemotherapy or those administered corticosteroids within 6 months of enrollment in the study were excluded. Between October 2010 and August 2014, 481 patients receiving chemotherapy underwent the rapid adrenocorticotropic hormone (ACTH) stimulation test to assess eligibility; 350 of these patients were included in the final analysis. Fifty-six patients (16.0%) showed a suppressed adrenal response in the rapid ACTH stimulation test at 3 or 6 months after the start of the first chemotherapy. The incidence of adrenal suppression was affected by age, performance status, stage, and use of megestrol acetate in univariate analysis. Multivariate analysis revealed that secondary adrenal suppression associated with antiemetic dexamethasone therapy was significantly associated with megestrol acetate treatment (odds ratio: 3.06; 95% confidence interval: 1.60 to 5.86; p < .001). This large prospective study indicates that approximately 15% of cancer patients receiving chemotherapy with a normal adrenal response show suppressed adrenal responses after antiemetic dexamethasone therapy. This result was particularly significant for patients cotreated with megestrol acetate. ©AlphaMed Press.

To assess the benefit of proactive palliative medicine consultation for delineation of goals of care and quality-of-life preferences before implantation of left ventricular assist devices as destination therapy (DT). We retrospectively reviewed the cases of patients who received DT between January 15, 2009, and January 1, 2010. Of 19 patients identified, 13 (68%) received proactive palliative medicine consultation. Median time of palliative medicine consultation was 1 day before DT implantation (range, 5 days before to 16 days after). Thirteen patients (68%) completed advance directives. The DT implantation team and families reported that preimplantation discussions and goals of care planning made postoperative care more clear and that adverse events were handled more effectively. Currently, palliative medicine involvement in patients receiving DT is viewed as routine by cardiac care specialists. Proactive palliative medicine consultation for patients being considered for or being treated with DT improves advance care planning and thus contributes to better overall care of these patients. Our experience highlights focused advance care planning, thorough exploration of goals of care, and expert symptom management and end-of-life care when appropriate.

Studies found an association between decreased 25-OH vitamin D blood level and prostate cancer progression. Vitamin D supplementation is controversial and dosage recommendations inconsistent. This study identified factors associated with 25-OH vitamin D levels and whether vitamin D supplementation with 800 IU/day raised vitamin D levels in prostate cancer patients receiving androgen deprivation therapy (ADT). We recruited 108 men treated with ADT for ≥9 months from eight cancer and urology practices. Sections of the NHANES 2005-2006 questionnaire and Canadian Fitness Survey were completed identifying age, ethnicity, length of ADT use, calcium supplementation ≥1000 IU mg/day, body mass index, exercise, alcohol and tobacco use, and vitamin D supplementation ≥800 IU/daily. Blood was collected for 25-OH vitamin D analysis. The majority of men (66%) had blood levels of 25-OH vitamin D <32 ng/mL. Regression analysis showed vitamin D supplementation (β = 6.556, CI 1.463, 11.650; p = .012) and African American ethnicity (β = -7.816, CI -12.996, -2.635; p = .003) is associated with 25-OH vitamin D level after controlling age and tobacco use. Findings support current recommendations for supplementation with ≥800 IU vitamin D/day for men receiving ADT. Nurse practitioners caring for prostate cancer patients receiving ADT should include vitamin D monitoring and supplementation. ©2014 American Association of Nurse Practitioners 2014.

The neutrophil-to-lymphocyte ratio (NLR) at diagnosis has been identified as an independent prognostic marker in several malignancies. Recently, a few studies have reported that an elevated pretreatment NLR is associated with poor survival among multiple myeloma (MM) patients. However, the role of NLR at diagnosis in patients with MM treated with regimens containing bortezomib has been less explored. We aimed to investigate the relationships between NLR and overall survival (OS) in newly diagnosed patients receiving bortezomib-based therapy for MM. A total of 76 newly diagnosed patients with MM treated with bortezomib-based regimes were analyzed retrospectively. NLR was calculated from whole blood counts prior to therapy and subsequently correlated with OS. Complete remission (CR) was seen in 39.2% of patients with NLR < 2.95 compared to 20% in the group with NLR ⩾ 2.95 (P= 0.094). NLR was lower in CR patients in comparison to Non-CR subjects (P= 0.044). Patients with a NLR ⩾ 2.95 experienced inferior median survival compared to those with NLR < 2.95 (4-year OS rates were 30.9% and 64.8%, respectively, P= 0.029). In multivariate analysis, only elevated LDH and IgA MM were factors predicting inferior OS. Elevated NLR was associated with poor OS in MM patients receiving induction therapy with bortezomib-based regimens, but it was not an independent prognostic factor in this patient cohort.

Transcranial direct current stimulation may enhance effect of rehabilitation in patients with chronic stroke. The objective was to evaluate the efficacy of anodal transcranial direct current stimulation combined with constraint-induced movement therapy of the paretic upper limb. A total of 44 patients with stroke were randomly allocated to receive 2 weeks of constraint-induced movement therapy with either anodal or sham transcranial direct current stimulation. The primary outcome measure, Wolf Motor Function Test, was assessed at baseline and after the intervention by blinded investigators. Both groups improved significantly on all Wolf Motor Function Test scores. Group comparison showed improvement on Wolf Motor Function Test in the anodal group compared with the sham group. Anodal transcranial direct current stimulation combined with constraint-induced movement therapy resulted in improvement of functional ability of the paretic upper limb compared with constraint-induced movement therapy alone.

Hepatosplenic T-cell lymphoma (HSTCL) is a rare, lethal disease generally seen in young male patients with inflammatory bowel disease. The study of biologic and immunomodulator naive patients in Crohn's disease (SONIC), advocates combining infliximab with an immunomodulator in moderate-to-severe Crohn's disease. Unfortunately, combined immunosuppression increases risk for HSTCL. We herein review all cases of HSTCL reported to the Food and Drug Administration (FDA) in patients receiving TNF-α inhibitors. Individual reports from the FDA Adverse Event Reporting System database for lymphomas from the biological agents - infliximab, adalimumab, certolizumab, natalizumab, and etanercept were downloaded and analyzed with Microsoft Access. Full reports for all identified HSTCL cases were obtained from the FDA. Twenty-five cases of HSTCL were identified. Twenty-two (88%) patients had inflammatory bowel disease and three had rheumatoid arthritis. Four cases (16%) were in women and four patients were above 65 years of age. Twenty-four cases (96%) also received an immunomodulator (azathioprine, 6-mercaptopurine, or methotrexate). Two patients received adalimumab alone. HSTCL is no longer restricted to the previously identified risk group of young male patients, but can also occur in patients with rheumatoid arthritis, females and older adults receiving TNF-α inhibitors and immunomodulators. Improved disease outcomes using combination therapy should be tempered by the risk of developing HSTCL.

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.

The goal of this study is to profile the metabolic changes in the plasma of HIV patients receiving lopinavir/ritonavir (LPV/r)-based highly active antiretroviral therapy (HAART) relative to their treatment-naïve phase, aimed to identify precision therapy for HIV for improving prognosis and predicting dyslipidemia caused by LPV/r. 38 longitudinal plasma samples were collected from 19 HIV-infected patients both before and after antiretroviral therapy, and 18 samples from healthy individuals were used as controls. Untargeted metabolomics profiling of these plasma samples was performed using liquid chromatography-mass spectrometry (LC-MS) and gas chromatography-mass spectrometry (GC-MS). A total of 331 compounds of known identity were detected among these metabolites, a 67-metabolite signature mainly mapping to tryptophan, histidine, acyl carnitine, ketone bodies and fatty acid metabolism distinguished HIV patients from healthy controls. The levels of 19 out of the 67 altered metabolites including histidine, kynurenine, and 3-hydroxybutyrate (BHBA), recovered after LPV/r-based antiretroviral therapy, and histidine was positively correlated with the presence of CD4 + T lymphocytes. Furthermore, using receiver operating characteristic (ROC) analyses, we discovered that butyrylcarnitine in combination with myristic acid from plasma in treatment-naïve patients could predict dyslipidemia caused by LPV/r with 87% accuracy. Metabolites alterations in treatment-naïve HIV patients may indicate an inflammatory, oxidative state and mitochondrial dysfunction that is permissive for disease progression. Histidine may provide a specific protective function for HIV patients. Besides, elevated fatty acids levels including butyrylcarnitine and myristic acid after infection may indicate patients at risk of suffering from dyslipidemia after LPV/r-based HAART.

The DIAS-2 study was the only large, randomized, intravenous, thrombolytic trial that selected patients based on the presence of ischemic penumbra. However, DIAS-2 did not confirm the positive findings of the smaller DEDAS and DIAS trials, which also used penumbral selection. Therefore, a reevaluation of the penumbra selection strategy is warranted. In post hoc analyses we assessed the relationships of magnetic resonance imaging-measured lesion volumes with clinical measures in DIAS-2, and the relationships of the presence and size of the diffusion-perfusion mismatch with the clinical effect of desmoteplase in DIAS-2 and in pooled data from DIAS, DEDAS, and DIAS-2. In DIAS-2, lesion volumes correlated with National Institutes of Health Stroke Scale (NIHSS) at both baseline and final time points (P<0.0001), and lesion growth was inversely related to good clinical outcome (P=0.004). In the pooled analysis, desmoteplase was associated with 47% clinical response rate (n=143) vs 34% in placebo (n=73; P=0.08). For both the pooled sample and for DIAS-2, increasing the minimum baseline mismatch volume (MMV) for inclusion increased the desmoteplase effect size. The odds ratio for good clinical response between desmoteplase and placebo treatment was 2.83 (95% confidence interval, 1.16-6.94; P=0.023) for MMV >60 mL. Increasing the minimum NIHSS score for inclusion did not affect treatment effect size. Pooled across all desmoteplase trials, desmoteplase appears beneficial in patients with large MMV and ineffective in patients with small MMV.

Abstract Objectives Antiestrogen therapy can cause vasomotor symptoms similar to those occurring during menopause, including hot flashes. Recent studies suggest that acupuncture is effective in reducing vasomotor symptoms in patients with breast cancer receiving tamoxifen. The purpose of this study was to assess the feasibility and safety of acupuncture for treatment of hot flashes in Korean patients with breast cancer receiving antiestrogen therapy. Design This was a prospective single-arm observational study using before and after measurements. Settings/location The study was located at the East–West Medical Center at Daegu Catholic University Medical Center, Daegu, Korea. Subjects The subjects were 10 patients with breast cancer who were undergoing antiestrogen therapy with tamoxifen or anastrozole and who were suffering from hot flashes. Interventions Acupuncture was administered 3 times a week for 4 consecutive weeks, for 20±5 minutes at each session. Outcome measures The outcome measure was severity of hot flashes assessed by visual analogue scale (VAS) and total hot flash score. Results During treatment, severity of hot flashes was reduced by 70%–95% in all patients. Acupuncture significantly alleviated severity of hot flashes assessed by a visual analogue scale (F=30.261; p<0.001) as well as the total hot flash score (F=21.698; p=0.006). Four (4) weeks after the final treatment, symptoms were not aggravated. Conclusions Acupuncture appeared to provide effective relief from hot flashes among Korean women receiving antiestrogen therapy after surgery for breast cancer, and the effects lasted for at least 1 month after termination of treatment. A randomized controlled prospective study with a larger sample size is required to clarify the role of acupuncture in the management of hot flashes in Korean patients with breast cancer.

The American Society of Clinical Oncology recommends that all patients with metastatic disease receive dedicated palliative care (PC) services early in their illness, ideally via interdisciplinary care teams. We investigated the time trends of specialty palliative care consultations from the date of metastatic cancer diagnosis among patients receiving palliative radiation therapy (PRT). A shorter time interval between metastatic diagnosis and first PC consultation suggests earlier involvement of palliative care in a patient's life with metastatic cancer. In this IRB-approved retrospective analysis, patients treated with PRT for solid tumors (bone and brain) at a single tertiary care hospital between 2010 and 2016 were included. Cohorts were arbitrarily established by metastatic diagnosis within approximately two-year intervals: (1) 1/1/2010-3/27/2012; (2) 3/28/2012-5/21/2014; and (3) 5/22/2014-12/31/2016. Cox-proportional hazards regression modelling was used to compare trends of PC consultation among cohorts. Of 284 patients identified, 184 patients received PC consultation, whereas 15 patients died before receiving a PC consult. Median follow-up time until an event or censor was 257 days (range: 1,900). Patients in the most recent cohort had a shorter median time to first PC consult (57 days) compared to those in the first (374 days) and second (186 days) cohorts. On multivariable analysis, patients in the third cohort were more likely to undergo a PC consultation earlier in their metastatic illness (HR: 1.8, 95% CI: 1.2,2.8). Over a six-year period, palliative care consultation occurred earlier for metastatic patients treated with PRT at our institution. Copyright © 2018. Published by Elsevier Inc.

Thrombosis is a major cause of several diseases, i.e. myocardial infarction, cerebral stroke and pulmonary embolism. Thrombolytic therapies are required to induce fast and efficient recanalization of occluded vessels. To evaluate the in vitro efficacy of these thrombolytic strategies, measuring clot dissolution is essential. This study aimed to evaluate and validate high resolution ultrasound as a tool to assess the exact volume of clots in 3D and in real time during in vitro thrombolytic drug testing. This new method was validated by measuring the effects of concentration range of recombinant tissue type plasminogen activator on a blood clot during complete occlusion or 70% stenosis of a vessel. This study shows that high resolution ultrasound imaging allows for a real-time assessment of the 3D volume of a blood clot with negligible inter- and intra-operator variabilities. The conclusions drawn from this study demonstrate the promising potential of high resolution ultrasound imaging for the in vitro assessment of new thrombolytic drugs.

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.

The observation that extremely high levels of medication adherence are required to achieve complete virologic suppression is based largely on studies of treatment-experienced patients receiving HIV protease inhibitor (PI)-based therapy without ritonavir boosting. This study aims to define the level of adherence needed to achieve virologic suppression in patients receiving boosted PI-based highly active antiretroviral therapy (HAART) with lopinavir/ritonavir. HIV-infected adults receiving a regimen containing lopinavir/ritonavir were recruited into a prospective, observational study of the relation between adherence to lopinavir/ritonavir and virologic outcomes. Adherence was measured using the Medication Event Monitoring System (MEMS; Aardex, Union City, CA). HIV-1 viral load (VL) was measured at week 24. The final study population contained 64 subjects. Eighty percent had AIDS, 97% received lopinavir/ritonavir before enrollment, and most had more than 7 years of HAART experience. Mean adherence overall was 73%. Eighty percent and 59% achieved a VL <400 copies/mL and a VL <75 copies/mL, respectively. Mean adherence was 75% in those achieving a VL <75 copies/mL. High rates of virologic suppression were observed in all adherence quartiles, including the lowest quartile (range of adherence: 23.5%-53.3%). Moderate levels of adherence can lead to virologic suppression in most patients taking lopinavir/ritonavir-based HAART.

Methadone maintenance therapy (MMT) is crucial for HIV prevention and treatment in people who inject opioids. In Malaysia, a large proportion of the prison population is affected by both HIV and opioid use disorders. This study assessed individual preferences and factors associated with interest in receiving MMT among male prisoners meeting criteria for opioid dependence in Malaysia. A convenience sample of 96 HIV-positive and 104 HIV-negative incarcerated men who met pre-incarceration criteria for opioid dependence was interviewed using a structured questionnaire to examine participant characteristics and attitudes toward MMT. Factors associated with interest in prison-based MMT initiation were identified using logistic regression analysis. Among all participants, 85 (42.5%) were interested in receiving MMT within prison. Independent correlates of interest in prison-based MMT were being previously married (AOR=4.15, 95% CI: 1.15, 15.02), previously incarcerated (AOR=5.68, 95% CI: 1.54, 21.02), depression (AOR=3.66, 95% CI: 1.68, 7.98), daily heroin use in the 30days prior to incarceration (AOR=5.53, 95% CI: 1.65, 18.58), and more favorable attitudes toward MMT (AOR=19.82, 95% CI: 6.07, 64.74). Overall, interest in receiving prison-based MMT was low, and was associated with adverse social, mental health, and drug use consequences. Incarceration provides a unique opportunity to initiate MMT for those who need it, however, optimal scale-up efforts must be systemic and address modifiable factors like improving attitudes toward and motivation for MMT. Informed or shared decision-making tools may be useful in improving expectations and acceptability of MMT. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Problems with attention and symptom distress are common clinical features reported by women who receive adjuvant chemotherapy for breast cancer. Mindfulness practice significantly improves attention and mindfulness programs significantly reduce symptom distress in patients with cancer, and, more specifically, in women with breast cancer. Recently, a pilot investigation of a music therapy program, built on core attitudes of mindfulness practice, reported significant benefits of enhanced attention and decreased negative mood and fatigue in women with breast cancer. This paper delineates the design and development of the mindfulness-based music therapy (MBMT) program implemented in that pilot study and includes clients’ narrative journal responses. Conclusions and recommendations, including recommendation for further exploration of the function of music in mindfulness practice are provided. PMID:27517966

Few data are available on the behavior of myocardial ischemia during daily activities in patients with coronary artery disease receiving antianginal drug therapy. To study the mechanism generating myocardial ischemia by evaluating blood pressure and heart rate changes in patients with stable atherosclerotic disease receiving drug therapy and with evidence of myocardial ischemia. Fifty non-hospitalized patients (40 males) underwent 24-hour electrocardiographic monitoring synchronized with blood pressured monitoring. Thirty five episodes of myocardial ischemia were detected in 17 patients, with a total duration of 146.3 minutes; angina was reported in five cases. Twenty nine episodes (100.3 minutes) occurred during wakefulness, with 11 episodes (35.3 + 3.7 min) in the period from 11 a.m. to 3 p.m. Blood pressure and heart rate evaluation in the three ten-minute intervals following the ischemic episodes showed a statistically significant difference (p< 0.05), unlike that shown for the three intervals preceding the episodes. However, during the ischemic episode, a higher than 10-mmHg elevation in blood pressure and 5 beats per minute in heart rate were observed when compared with the time interval between 20 and 10 minutes before the episode. The mean heart rate at the onset of ischemia during the exercise test performed before the study was 118.2 + 14.0, and 81.1 + 20.8 beats per minute on the 24-hour electrocardiogram (p < 0.001). The incidence of silent myocardial ischemia is high in stable coronary artery disease and is related to alterations in blood pressure and heart rate, with different thresholds for ischemia for the same patient.

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. 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. 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. 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.

University hospital. Subjects who received radiation therapy (RT) for the treatment of head and neck cancer were divided into two groups: an oral cavity irradiated group (OIRR group, n = 29) and an oral cavity nonirradiated group (ONIRR group, n = 17). A control group consisted of 18 healthy subjects. Patients were examined for signs of oral candidiasis before, during, immediately after, and one month after RT. Mouth and throat soreness (MTS), dysphagia, and xerostomia were evaluated by self-reported questionnaires, and associations between oral candidiasis and these symptoms were analyzed. The incidence of oral candidiasis during RT was significantly higher in the OIRR group (55.2%) than in the ONIRR group (11.8%). Similarly, the occurrence of xerostomia during RT was significantly higher in the OIRR group (86.2%) than in the ONIRR group (52.9%). In the OIRR group, the mean MTS score at the 20th fraction of RT was significantly higher in patients with candidiasis (mean +/- SD, 5.8 +/- 2.1) than in those with RT-induced mucositis without candidiasis (3.7 +/- 2.0). In the OIRR group, 65.2 percent of patients who experienced dysphagia developed oral candidiasis, compared with only 10 percent in the ONIRR group. Oral candidiasis concurrent with oral mucositis due to RT may increase oropharyngeal discomfort during RT. Copyright (c) 2010 American Academy of Otolaryngology-Head and Neck Surgery Foundation.

The effectiveness of psychological therapies for those receiving acute adult mental health inpatient care remains unclear, partly because of the difficulty in conducting randomized controlled trials (RCTs) in this setting. The aim of this meta-analysis was to synthesize evidence from all controlled trials of psychological therapy carried out with this group, to estimate its effects on a number of important outcomes and examine whether the presence of randomization and rater blinding moderated these estimates. A systematic review and meta-analysis of all controlled trials of psychological therapy delivered in acute inpatient settings was conducted, with a focus on psychotic symptoms, readmissions or emotional distress (anxiety and depression). Studies were identified through ASSIA, EMBASE, CINAHL, Cochrane, MEDLINE, and PsycINFO using a combination of the key terms 'inpatient', 'psychological therapy', and 'acute'. No restriction was placed on diagnosis. The moderating effect of the use of assessor-blind RCT methodology was examined via subgroup and sensitivity analyses. Overall, psychological therapy was associated with small-to-moderate improvements in psychotic symptoms at end of therapy but the effect was smaller and not significant at follow-up. Psychological therapy was also associated with reduced readmissions, depression, and anxiety. The use of single-blind randomized controlled trial methodology was associated with significantly reduced benefits on psychotic symptoms and was also associated with reduced benefits on readmission and depression; however, these reductions were not statistically significant. The provision of psychological therapy to acute psychiatric inpatients is associated with improvements; however, the use of single-blind RCT methodology was associated with reduced therapy-attributable improvements. Whether this is a consequence of increased internal validity or reduced external validity is unclear. Trials with both high internal and

To examine the effect of relaxation therapy on reducing patient anxiety and pain before and after total joint replacement. Despite the use of analgesics, patients may feel anxiety and pain before and after surgery, delaying their recovery. An experimental control group pretest-post-test quasi-experimental design was employed. Subjects (n = 93) recruited from a medical centre in Taipei, Taiwan, from November 2006-March 2007 were randomly assigned to experimental (n = 45) and control (n = 48) groups. Subjects in the experimental group received relaxation therapy from the day before surgery to the third postoperative day. Researchers helped participants listen to a breath relaxation and guided imagery tape for 20 minutes daily. A pain and anxiety scale questionnaire, the State-Trait Anxiety Inventory questionnaire, blood pressure and heart rate were monitored before and after intervention. The average age of the 93 patients was 71·0 (SD 11·1) years. The least pain severity scores in the experimental were lower than those in the control group (p < 0·05) but both experienced the same level of worst or average pain (p > 0·05). The mean difference in the pain score before and after intervention in the experimental group on the pre-op day (t = 2·675, p = 0·009) and post-op day one (t = 3·059, p = 0·003) was greater than that in the control group (0·48 SD 0·94 vs. 0·10 SD 0·30 and 0·93 SD 1·46 vs. 0·20 SD 0·71, respectively). The two groups differed significantly in systolic blood pressure (F = 6·750, p < 0·05) but not in mean blood pressure, heart rate, or State-Trait Anxiety Inventory scores (p > 0·05). Patients reported that relaxation therapy helped them relax and promoted sleep. Relaxation therapy could complement analgesics to help postoperative patients better manage pain and anxiety. Clinical practice should include complementary relaxation therapy to alleviate pain and anxiety in patients with joint replacement. © 2011 Blackwell Publishing Ltd.

On-treatment response of serum hepatitis C virus (HCV) is reportedly less useful to predict the outcome of anti-HCV therapy with interferon (IFN)-free regimen with direct-acting antivirals than with IFN-based regimens in clinical trials. We evaluated the significance of very early viral response after the start of therapy, which indicates direct HCV response to the drugs, on therapeutic outcome. Reductions in serum HCV-RNA levels were measured at 1 day after the start of therapy in 544 patients who underwent IFN-free direct-acting antiviral regimens. The association between these reductions and the achievement or failure of sustained virologic response (SVR) was evaluated. Patient characteristics did not influence 1-day reduction in serum HCV-RNA except for liver fibrosis. There was no difference in 1-day HCV reduction between SVR and non-SVR patients treated with a 24-week regimen. In contrast, in patients treated with a 12-week regimen, 1-day reduction was significantly greater in SVR than in non-SVR patients (P = 0.0013) and was predictive of SVR versus non-SVR (area under the receiver-operating characteristics curve: 0.80). Whereas the reduction in serum HCV-RNA levels at 1 day after the start of therapy was not associated with treatment outcomes in patients who underwent a 24-week regimen of IFN-free therapy, there was an association in patients receiving a 12-week regimen, and this reduction was predictive of SVR, thus potentially serving as a factor to identify patients at risk of treatment failure. © 2017 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.

Little is known about the clinical characteristics of patients with dementia receiving electroconvulsive therapy (ECT) for the treatment of behavioral symptoms. This study examined the demographic and clinical profile of patients with dementia receiving ECT in China. This was a retrospective, case-control study. The sample was composed of 23 patients with dementia treated with ECT and 71 sex- and age-matched controls treated for a period of 8 years (2007-2014) at the National Clinical Research Centre of Mental Disorders, China. Sociodemographic and clinical data were collected from the electronic chart management system. Multiple logistic regression analysis revealed that ECT was independently associated with high risk for suicide at admission. The recorded indications for ECT included both high risk for suicide and aggressive behavior. Most patients responded to ECT satisfactorily (56.5%) or partially (34.8%) with only mild-moderate transient memory impairment (30.4%). Although this is a preliminary study limited by the retrospective design and small sample size, findings suggest that ECT is an effective and safe therapeutic intervention to reduce the risk for suicide and aggressive behavior in dementia.

The advent of antiretroviral therapy has significantly improved AIDS-related morbidity and mortality. Yet, among people living with HIV, deaths due to non-AIDS-defining illnesses have been on the rise. The objective of this study was to provide information about the global prevalence and distribution of non-AIDS causes of death in the last ten years among people living with HIV receiving antiretroviral therapy, by income levels of countries. We used broad search terms in Google Scholar, PubMed, and EMBASE to identify all studies that investigated the cause of death among people living with HIV receiving antiretroviral therapy, published after January 1, 2005. References were also identified from review articles and reference lists. Inclusion criteria were English language, the study's end date was after 2005, all patients were HIV-positive, at least two-thirds of the patients were receiving antiretroviral therapy, at least one patient died of non-AIDS causes of death. Titles, abstracts, and articles were reviewed by at least two independent readers. Of 2951 titles identified in our original search, 151 articles were selected for further screening. We identified 19 studies meeting our full criteria, with patients from 55 different nations. Pooled non-AIDS causes of death prevalence estimates in high-income countries were 53.0% (95% confidence interval, 43.6-62.3), in developing countries 34.0% (95% confidence interval, 20.3-49.1), and in sub-Saharan countries 18.5% (95% confidence interval, 13.8-23.7). Statistically significant variation was noted within and between categories. Our findings show that a significant number of people living with HIV across the world die from cardiovascular disease, non-AIDS malignancies, and liver disease. There is a global need for further scrutiny in all regions to improve preventive measures and early detection according to distinct causes of death patterns.

Prognostic factors in men with penile squamous cell carcinoma (PSCC) receiving systemic therapy are unknown. A prognostic classification system in this disease may facilitate interpretation of outcomes and guide rational drug development. We performed a retrospective analysis to identify prognostic factors in men with PSCC receiving first-line systemic therapy for advanced disease. Individual patient level data were obtained from 13 institutions to study prognostic factors in the context of first-line systemic therapy for advanced PSCC. Cox proportional hazards regression analysis was conducted to examine the prognostic effect of these candidate factors on progression-free survival (PFS) and overall survival (OS): age, stage, hemoglobin, neutrophil count, lymphocyte count, albumin, site of metastasis (visceral or nonvisceral), smoking, circumcision, regimen, ECOG performance status (PS), lymphovascular invasion, precancerous lesion, and surgery following chemotherapy. The effect of different treatments was then evaluated adjusting for factors in the prognostic model. The study included 140 eligible men. Mean age across all men was 57.0 years. Among them, 8.6%, 21.4%, and 70.0% of patients had stage 2, 3, and 4 diseases, respectively; 40.7% had ECOG PS ≥ 1, 47.4% had visceral metastases, and 73.6% received cisplatin-based chemotherapy. The multivariate model of poor prognostic factors included visceral metastases (P<0.001) and ECOG PS ≥ 1 (P<0.001) for both PFS and OS. A risk stratification model constructed with 0, 1, and both poor prognostic factors was internally validated and demonstrated moderate discriminatory ability (c-statistic of 0.657 and 0.677 for OS and PFS, respectively). The median OS for the entire population was 9 months. Median OS was not reached, 8, and 7 months for those with 0, 1, and both risk factors, respectively. Cisplatin-based regimens were associated with better OS (P = 0.017) but not PFS (P = 0.37) compared with noncisplatin

This was a retrospective study using a large U.S. health insurance claims database spanning 1/97-12/04 and representing 40 million members in >70 health plans. Study subjects (n = 145 total, 106 sickle cell disease [SCD], 39 thalassemia) included members with a diagnosis of thalassemia or SCD, one or more transfusions (whole blood or red blood cells), and one or more claims for DFO. Mean transfusion episodes were 12 per year. Estimated mean DFO use was 307 g/year. Central venous access devices were required by 20% of patients. Cardiac disease was observed in 16% of patients. Mean total medical costs were $59,233 per year including $10,899 for DFO and $8,722 for administration of chelation therapy. In multivariate analyses, potential complications of iron overload were associated with significantly higher medical care costs. In typical clinical practice, use of DFO in patients with thalassemia and SCD receiving transfusions is low. Administration costs represent a large proportion of the cost of chelation therapy. Potential complications of iron overload are associated with increased costs. (c) 2007 Wiley-Liss, Inc.

Antibody-mediated pure red cell aplasia (PRCA) has been primarily observed in patients with chronic kidney disease treated with an erythropoiesis-stimulating agent (ESA); only a few anecdotal cases have been reported in other patient populations. We searched the Amgen Global Safety Adverse Event Database and identified 14 patients with hepatitis C who developed severe anemia, anti-erythropoietin antibodies, and bone marrow biopsy-proven PRCA, while receiving interferon therapy (with or without ribavirin) and an ESA. During the follow-up period and after ESA treatment stopped, 11 patients no longer required transfusions and 3 did. Analysis of antibody isotypes showed that, contrary to reports of patients with chronic kidney disease, immunoglobulin G1 was the predominant isotype rather than immunoglobulin G4 (immunoglobulin G4 was detected in only 1 of 6 patients). Epitope mapping showed the anti-erythropoietin antibodies bound domains required for receptor binding. Therefore, the potential benefits of ESA therapy must be weighed against the risk for PRCA in patients with hepatitis C who are receiving treatment with interferon and ribavirin.

Data on the incidence of adverse liver outcomes are limited for cancer patients with chronic (hepatitis B surface antigen [HBsAg]-positive/hepatitis B core antibody [anti-HBc]-positive) or past (HBsAg-negative/anti-HBc-positive) hepatitis B virus (HBV) after chemotherapy. This study was aimed at determining the impact of test timing and anti-HBV therapy on adverse liver outcomes in these patients. Patients with solid or hematologic malignancies who received chemotherapy between 2004 and 2011 were retrospectively studied. HBV testing and anti-HBV therapy were defined as early at the initiation of cancer therapy and as late after initiation. Outcomes included hepatitis flares, hepatic impairment, liver failure, and death. Time-to-event analysis was used to determine incidence, and multivariate hazard models were used to determine predictors of outcomes. There were 18,688 study patients (80.4% with solid tumors). The prevalence of chronic HBV was 1.1% (52 of 4905), and the prevalence of past HBV was 7.1% (350 of 4905). Among patients with solid tumors, late identification of chronic HBV was associated with a higher risk of hepatitis flare (hazard ratio [HR], 4.02; 95% confidence interval [CI], 1.26-12.86), hepatic impairment (HR, 8.48; 95% CI, 1.86-38.66), liver failure (HR, 9.38; 95% CI, 1.50-58.86), and death (HR, 3.90; 95% CI, 1.19-12.83) in comparison with early identification. Among patients with hematologic malignancies and chronic HBV, the risk of death was 7.8 (95% CI, 1.73-35.27) times higher for persons with late initiation of anti-HBV therapy versus early initiation. Patients with late identification of chronic HBV had late or no anti-HBV therapy. Chronic HBV predicted liver failure in patients with solid or hematologic malignancies, whereas male sex and late identification were predictors for patients with solid tumors. Early identification correlates with early anti-HBV therapy and reduces the risk of liver failure and death in chronic HBV patients

The objective of this study was to present initial systemic treatment choices and the outcome of hormone receptor-positive (HR+) metastatic breast cancer. All the 815 consecutive patients diagnosed with metastatic breast cancer in 2007-2009 in eight participating hospitals were identified. From the 611 patients with HR+ disease, a total of 520 patients with HER2-negative (HER2-) breast cancer were included. Initial palliative systemic treatment was registered. Progression-free survival (PFS) and overall survival (OS) per initial palliative systemic therapy were obtained using the Kaplan-Meier method and compared using the log-rank test. From the total of 520 patients with HR+/HER2- metastatic breast cancer, 482 patients (93%) received any palliative systemic therapy. Patients that received initial chemotherapy (n = 116) were significantly younger, had less comorbidity, had received more prior adjuvant systemic therapy and were less likely to have bone metastasis only compared with patients that received initial endocrine therapy (n = 366). Median PFS of initial palliative chemotherapy was 5.3 months [95% confidence interval (CI) 4.2-6.2] and of initial endocrine therapy 13.3 months (95% CI 11.3-15.5), with a median OS of 16.1 and 36.9 months, respectively. Initial chemotherapy was also associated with worse outcome in terms of PFS and OS after adjustment for prognostic factors. A high percentage of patients with HR+ disease received initial palliative chemotherapy, which was associated with worse outcome, even after adjustment of relevant prognostic factors. © The Author 2015.

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. PMID:25337944

Prostate cancer patients who receive androgen deprivation therapy (ADT) often experience many physical and psychological side effects. ADT may be associated with increased risk for depression, but the relationship between ADT and depression is not fully understood. This study used a longitudinal design to assess depressive symptomatology in patients receiving ADT compared with two groups of matched controls. Participants were men initiating ADT treatment (ADT+ group; n = 61) and their matched controls: prostate cancer patients treated with radical prostatectomy (ADT- group; n = 61), and no-cancer controls (CA- group; n = 61). Depressive symptomatology was assessed using the Center for Epidemiological Studies Depression Scale at ADT initiation and again 6 months later. Differences in depressive symptomatology and rates of clinically significant depressive symptomatology were analyzed between groups at each time point and within groups over time. Between baseline and follow-up, ADT+ participants demonstrated increased depressive symptomatology and increased rates of clinically significant depressive symptomatology (ps < 0.05). ADT+ participants also reported greater depressive symptomatology than both control groups at follow-up (ps < 0.001). Rates of clinically significant depressive symptomatology were higher in the ADT+ group than the ADT- and CA- groups at both time points (baseline: 28%, 5%, 12%; follow-up: 39%, 9%, 11%). Findings support the hypothesis that ADT administration yields increases in depression and suggest that the mechanism behind ADT's association with depression should be explored and that prostate cancer patients treated with ADT should receive particular focus in depression screening and intervention.

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

To compare the effect of Plasma-Lyte (PL)-148 and saline 0.9% (saline) on gastrointestinal (GI) feeding intolerance in mechanically ventilated patients receiving nasogastric (NG) feeding in an intensive care unit. A single-centre pilot study, nested within a multicentre, double-blind, cluster-randomised, double-crossover trial, performed in a mixed medical and surgical ICU. All adult patients who required crystalloid fluid therapy as part of the 0.9% Saline versus Plasma-Lyte 148 for Intensive Care Unit Fluid Therapy (SPLIT) trial, were expected to need mechanical ventilation for more than 48 hours and were receiving enteral nutrition exclusively by NG tube were eligible. We enrolled 69 patients and assigned 35 to PL-148 and 34 to saline. We randomly allocated saline or PL-148 for four alternating 7-week blocks, with staff blinded to the solution. The primary outcome was the proportion of patients with GI feeding intolerance, defined as high gastric residual volume (GRV), diarrhoea or vomiting while receiving NG feeding in the ICU. The proportions of patients with each of high GRV, diarrhoea and vomiting were secondary outcomes. In the PL-148 group, 21 of 35 patients (60.0%) developed GI feeding intolerance, compared with 22 of 34 patients (64.7%) in the saline group (odds ratio [OR], 0.82; 95% CI, 0.31-2.17; P = 0.69). A high GRV was seen in four of 35 patients (11.4%) in the PL-148 group, and in 11 of 34 patients (32.4%) in the saline group (OR, 0.27; 95% CI, 0.08-0.96; P = 0.04). Among mechanically ventilated patients receiving NG feeding, the use of PL-148, compared with saline, did not reduce the proportion of patients developing GI feeding intolerance, but was associated with a decreased incidence of high GRV.

Endovascular therapy for acute ischemic stroke.

To review advances in endovascular therapy for acute ischemic stroke. Data from primate studies, randomized studies of intravenous recombinant tissue-type plasminogen activator, and nonrandomized and randomized studies of endovascular therapy were reviewed. Clinical trial data demonstrate the superiority of endovascular treatment with thrombolytic medication or mechanical methods to reopen arteries compared with control patients from the PROACT II Trial treated with heparin alone. However, these same clinical trials, as well as preclinical primate models, indicate that recanalization, whether by endovascular approaches or standard-dose recombinant tissue-type plasminogen activator, is unlikely to improve clinical outcome after a certain time point. Although the threshold beyond which reperfusion has no or little benefit has yet to be conclusively defined, accumulated data to this point indicate an overall threshold of approximately 6 to 7 hours. In addition, although the risk of symptomatic intracerebral hemorrhage is similar in trials of intravenous lytics and endovascular approaches, endovascular approaches have distinctive risk profiles that can impact outcome. The treatment of acute ischemic stroke is evolving with new tools to reopen arteries and salvage the ischemic brain. Ongoing randomized trials of these new approaches are prerequisite next steps to demonstrate whether reperfusion translates into clinical effectiveness. Physiologic time to reperfusion will remain critical no matter which tools prove most effective and safest.

The Patient-Reported Outcomes Measurement Information System (PROMIS) is a universally applicable set of instruments, including item banks, short forms and computer adaptive tests (CATs), measuring patient-reported health across different patient populations. PROMIS CATs are highly efficient and the use in practice is considered feasible with little administration time, offering standardized and routine patient monitoring. Before an item bank can be used as CAT, the psychometric properties of the item bank have to be examined. Therefore, the objective was to assess the psychometric properties of the Dutch-Flemish PROMIS Physical Function item bank (DF-PROMIS-PF) in Dutch patients receiving physical therapy. Cross-sectional study. 805 patients >18 years, who received any kind of physical therapy in primary care in the past year, completed the full DF-PROMIS-PF (121 items). Unidimensionality was examined by Confirmatory Factor Analysis and local dependence and monotonicity were evaluated. A Graded Response Model was fitted. Construct validity was examined with correlations between DF-PROMIS-PF T-scores and scores on two legacy instruments (SF-36 Health Survey Physical Functioning scale [SF36-PF10] and the Health Assessment Questionnaire Disability-Index [HAQ-DI]). Reliability (standard errors of theta) was assessed. The results for unidimensionality were mixed (scaled CFI = 0.924, TLI = 0.923, RMSEA = 0.045, 1th factor explained 61.5% of variance). Some local dependence was found (8.2% of item pairs). The item bank showed a broad coverage of the physical function construct (threshold-parameters range: -4.28-2.33) and good construct validity (correlation with SF36-PF10 = 0.84 and HAQ-DI = -0.85). Furthermore, the DF-PROMIS-PF showed greater reliability over a broader score-range than the SF36-PF10 and HAQ-DI. The psychometric properties of the DF-PROMIS-PF item bank are sufficient. The DF-PROMIS-PF can now be used as short forms or CAT to measure the level of physical

The CAEP Stroke Practice Committee was convened in the spring of 2013 to revisit the 2001 policy statement on the use of thrombolytic therapy in acute ischemic stroke. The terms of reference of the panel were developed to include national representation from urban academic centres as well as community and rural centres from all regions of the country. Membership was determined by attracting recognized stroke leaders from across the country who agreed to volunteer their time towards the development of revised guidance on the topic. The guideline panel elected to adopt the GRADE language to communicate guidance after review of existing systematic reviews and international clinical practice guidelines. Stroke neurologists from across Canada were engaged to work alongside panel members to develop guidance as a dyad-based consensus when possible. There was no unique systematic review performed to support this guidance, rather existing efficacy data was relied upon. After a series of teleconferences and face to face meetings, a draft guideline was developed and presented to the CAEP board in June of 2014. The panel noted the development of significant new evidence to inform a number of clinical questions related to acute stroke management. In general terms the recommendations issued by the CAEP Stroke Practice Committee are supportive of the use of thrombolytic therapy when treatment can be administered within 3 hours of symptom onset. The committee is also supportive of system-level changes including pre-hospital interventions, the transport of patients to dedicated stroke centers when possible and tele-health measures to support thrombolytic therapy in a timely window. Of note, after careful deliberation, the panel elected to issue a conditional recommendation against the use of thrombolytic therapy in the 3–4.5 hour window. The view of the committee was that as a result of a narrow risk benefit balance, one that is considerably narrower than the same considerations

Why are some HIV/AIDS patients reluctant to receive antiviral therapy as soon as possible in China?

PubMed

Sun, Yang; Lu, Hongzhou

2014-06-01

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.

We compared two interferon gamma release assays (IGRAs), QuantiFERON-TB Gold In-Tube (QFT-GIT) and T-SPOT.TB, for diagnosis of latent tuberculosis infection (LTBI) in patients before and while receiving tumor necrosis factor (TNF)-α antagonist therapy. This study evaluated the significance of sensitive IGRAs for LTBI screening and monitoring. Before starting TNF-α antagonist therapy, 156 consecutive patients with rheumatic diseases were screened for LTBI using QFT-GIT and T-SPOT.TB tests. According to our study protocol, QFT-GIT-positive patients received LTBI treatment. Patients positive by any IGRAs were subjected to follow-up IGRA tests after completing LTBI-treatment and/or during TNF-α antagonist therapy. At the initial LTBI screening, 45 (28.9%) and 70 (44.9%) patients were positive by QFT-GIT and T-SPOT.TB, respectively. The agreement rate between IGRA results was 78.8% (k = 0.56; 95% confidence interval [95% CI] = 0.43 to 0.68). Of 29 patients who were positive only by T-SPOT.TB in the initial screening, 83% (19/23) were persistently positive by T-SPOT.TB, while QFT-GIT testing showed that 36% (9/25) had conversion during TNF-α antagonist therapy. By the end of the follow-up period (218 to 1,264 days), four patients (4/137, 2.9%) developed active tuberculosis (TB) diseases during receiving TNF-α antagonist therapy. Among them, one was Q-T+, one was Q+T-, and the remaining two were Q-T- at the initial screening (Q, QuantiFERON-TB Gold In-Tube; T, T-SPOT.TB; +, positive; -, negative). Two (2/4, 50%) patients with TB reactivation had at least one prior risk factor consistent with previous TB infection. This study demonstrated the need to capitalize on sensitive IGRAs to monitor for LTBI in at-risk patients for a more sensitive diagnosis in countries with an intermediate TB burden.

Cisplatin is a known nephrotoxic agent requiring vigorous hydration before use. However, aggressive hydration could be life-threatening. Therefore, in cirrhotic patients with advanced hepatocellular carcinoma (HCC) under cisplatin-based chemotherapy, the risk of nephrotoxicity increased. Because previous studies showed that long-term telbivudine treatment improved renal function in chronic hepatitis B virus (HBV) infected patients, we conducted a case-control study to evaluate the clinical outcome of telbivudine preemptive therapy in HBV-related advanced HCC patients treated by combination chemotherapy comprising 5-fluorouracil, mitoxantrone and cisplatin (FMP). From June 2007 to March 2012, 60 patients with HBV-related advanced HCC, all receiving the same FMP chemotherapy protocol, were enrolled. Of them, 20 did not receive any antiviral therapy, whereas the remaining 40 patients (sex and age matched) received telbivudine preemptive therapy. Progressive decrease of aminotransferase levels (p < 0.05) and progressive increase of viral clearance rates (p < 0.001) were found in telbivudine-treated group. No drug resistance developed during the course of treatment. When compared with non-antiviral-treated patients, a significantly higher post-therapeutic estimated glomerular filtration rate (eGFR) was found in the telbivudine-treated group (p < 0.001). In patients with initial eGFR >100 ml/min (n = 34), the median overall survival was significantly longer in the telbivudine-treated group (12.1 vs. 4.9 months; p = 0.042). Preemptive use of telbivudine significantly prevented eGFR deterioration caused by cisplatin-based chemotherapy in HBV-related advanced HCC. In patients with initially sufficient eGFR level, telbivudine treatment was associated with a longer overall survival.

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

The experience and expectations of terminally ill patients receiving music therapy in the palliative setting: a systematic review.

PubMed

Qi He Mabel, Leow; Drury, Vicki Blair; Hong, Poon Wing

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

None. Nutrition variables: initial and maximal protein (g/kg/day) and caloric (kcal/kg/day) prescription and predicted resting energy expenditure (kcal/kg/day). We determined factors predicting initial and maximal protein and caloric prescription by multivariate analysis. One hundred ninety-five patients (median [interquartile range] age = 8.1 [12.8] yrs, 56.9% men) were studied. Mean protein and caloric prescriptions at continuous renal replacement therapy initiation were 1.3 +/- 1.5 g/kg/day (median, 1.0; range, 0-10) and 37 +/- 27 kcal/kg/day (median, 32; range, 0-107). Mean maximal protein and caloric prescriptions during continuous renal replacement therapy were 2.0 +/- 1.5 g/kg/day (median, 1.7; range, 0-12) and 48 +/- 32 kcal/kg/day (median, 43; range, 0-117). Thirty-four percent of patients were initially prescribed < 1 g/kg/day protein; 23% never attained > 1 g/kg/day protein prescription. By continuous renal replacement therapy day 5, median protein prescribed was > 2 g/kg/day. Protein prescription practices differed substantially between medical centers with 5 of 10 centers achieving maximal protein prescription of > 2 g/kg/day in > or = 40% of patients. Caloric prescription exceeded predicted resting energy expenditure by 30%-100%. Factors independently associated with maximal protein

To determine the contribution of injectable iron administered to hemodialysis (HD) patients in causing oxidative stress and the beneficial effect of N-acetylcysteine (NAC) in reducing it, we studied in a prospective, double blinded, randomized controlled, cross over trial 14 adult HD patients who were randomized into two groups; one group received NAC in a dose of 600 mgs twice daily for 10 days prior to intravenous iron therapy and the other group received placebo. Both the groups were subjected to intravenous iron therapy, 100 mg of iron sucrose in 100 mL of normal saline given over a period of one hour. Blood samples for the markers of oxidative stress were taken before and after iron therapy. After the allowance of a week of wash out period for the effect of N-acetylcysteine we crossed over the patients to the opposite regimen. We measured the lipid peroxidation marker, malondiaaldehyde (MDA), to evaluate the oxidative stress and total anti-oxidant capacity (TAC) for the antioxidant level in addition to the highly sensitive C-reactive protein (HsCRP). Non-invasive assessment of endothelial dysfunction was measured by digital plethysmography before and after intravenous iron therapy. There was an increase of MDA (21.97 + 3.65% vs 7.06 + 3.65%) and highly sensitive C-reactive protein (HsCRP) (11.19 + 24.63% vs 13.19 + 7.7%) after iron administration both in the placebo and the NAC groups. NAC reduced the baseline acute systemic generation of oxidative stress when compared to placebo, which was statistically significant with MDA (12.76 + 4.4% vs 9.37 + 4.40%: P = 0.032) but not with HsCRP though there was a declining trend (2.85 + 22.75 % vs 8.93 + 5.19%: P = 0.112). Pre-treatment with NAC reduced the endothelial dysfunction when compared to placebo, but it was not statistically significant, except for reflection index (RI). We conclude that in our HD patients NAC reduced the oxidative stress before and after the administration of intravenous iron therapy in

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

Men who receive bone-targeted therapy for metastatic prostate cancer are at increased risk of osteonecrosis of the jaw (ONJ). Development of ONJ has been associated with the administration of bone-targeted therapies in association with other risk factors. ONJ can be distressing for a patient because it can cause pain, risk of jaw fracture, body image disturbance, difficultly eating, and difficulty maintaining good oral hygiene. The aim of this article is to report results of an audit of prior assessment by oral and maxillofacial surgeons (OMFS) before initiation of bone-targeted therapies and whether it may reduce the risk of ONJ in patients receiving bone-targeted therapies for advanced cancers.

Hindley, Andrew, E-mail: andrew.hindley@lthtr.nhs.uk; Zain, Zakiyah; Wood, Lisa

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 MFmore » 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.« less

The diagnostic value of gadolinium-DTPA (diethylenetriamine penta-acetic acid) enhanced magnetic resonance imaging in patients treated by thrombolysis for acute myocardial infarction was assessed in 27 consecutive patients who had a first acute myocardial infarction (14 anterior, 13 inferior) and who underwent thrombolytic treatment and coronary arteriography within 4 hours of the onset of symptoms. Magnetic resonance imaging was performed 93 hours (range 15-241) after the onset of symptoms. A Philips Gyroscan (0.5 T) was used, and spin echo measurements (echo time 30 ms) were made before and 20 minutes after intravenous injection of 0.1 mmol/kg gadolinium-DTPA. In all patients contrast enhancement of the infarcted areas was seen after Gd-DTPA. The signal intensities of the infarcted and normal values were used to calculate the intensity ratios. Mean (SD) intensity ratios after Gd-DTPA were significantly increased (1.15 (0.17) v 1.52 (0.29). Intensity ratios were higher in the 17 patients who underwent magnetic resonance imaging more than 72 hours after the onset of symptoms than in the 10 who underwent magnetic resonance imaging earlier, the difference being significantly greater after administration of Gd-DTPA (1.38 (0.12) v 1.61 (0.34). When patients were classified according to the site and size of the infarcted areas, or to reperfusion (n = 19) versus non-reperfusion (n = 8), the intensity ratios both before and after Gd-DTPA did not show significant differences. Magnetic resonance imaging with Gd-DTPA improved the identification of acutely infarcted areas, but with current techniques did not identify patients in whom thrombolytic treatment was successful.

Thrombolytics are currently the most effective treatment for stroke. However, the National Institute for Neurological Disorders and Stroke criteria for initiation of thrombolytic therapy, most notably the 3-hour time limit from symptom onset, have proven challenging for many rural hospitals to achieve. To provide a snapshot of stroke care at rural hospitals in Idaho and to investigate the experiences of these hospitals in expediting stroke care. Using a standard questionnaire, a telephone survey of hospital staff at 21 rural hospitals in Idaho was performed. The survey focused on acute stroke care practices and strategies to expedite stroke care. The median number of stroke patients treated per year was 23.3. Patient delays were reported by 77.8% of hospitals, transport delays by 66.7%, in-hospital delays by 61.1%, equipment delays by 22.2%, and ancillary services delays by 61.1%. Approximately 67% of hospitals had implemented a clinical pathway for stroke and 80.0% had provided staff with stroke-specific training. No hospitals surveyed had a designated stroke team, and only 33.3% reported engaging in quality improvement efforts to expedite stroke care. Thrombolytics (tPA) were available and indicated for stroke at 55.6% of the hospitals surveyed. Rural hospitals in Idaho face many difficult challenges as they endeavor to meet the 3-hour deadline for thrombolytic therapy, including limited resources and experience in acute stroke care, and many different types of prehospital and in-hospital delays.

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.

Children receiving stimulants for attention deficit hyperactivity disorder (ADHD) frequently present to pediatric endocrinology clinics for evaluation and treatment of growth disorders. The worldwide prevalence of stimulant use in children with ADHD also receiving recombinant human growth hormone (rhGH) and the impact on response to rhGH are unknown. Data on children enrolled in the KIGS® (Pfizer International Growth Study) registry were evaluated for the associated diagnosis of ADHD prior to initiation of Genotropin® rhGH. Concomitant stimulant medications and auxological information were captured. Response to rhGH was evaluated using established growth prediction models. The prevalence of ADHD in KIGS was 2.3% (1,748/75,251), with stimulants used in 1.8% (1,326/75,251). Children with idiopathic growth hormone deficiency (IGHD) who received stimulants grew significantly less (1.1 cm) in the first year of rhGH therapy than expected for rhGH-treated non-ADHD IGHD children. After one year of rhGH, idiopathic short stature (ISS) children with ADHD were significantly shorter [0.74 cm (with stimulants) and 0.69 cm (without stimulants)] than non-ADHD ISS children. We demonstrated an impaired response to rhGH in IGHD and ISS children with ADHD. Our findings suggest that the ADHD phenotype, alone or in conjunction with stimulant therapy, may impair the short-term growth response to rhGH.

Iron overload is a common problem in patients with primary myelofibrosis and anemia due to transfusion dependency. This results in organ damage and toxic effects on hematopoietic cells in the bone marrow. At present, iron chelation therapy is not recommended in patients with myeloproliferative syndromes. We describe a very interesting development in a patient with primary myelofibrosis receiving iron chelation. Transfusion independency and a nearly complete histological remission of the underlying disease occurred within a few weeks of therapy. In addition, a change in molecular genetic findings was observed. Initially a JAK2 and a U2AF1 mutation were detected in the core biopsy. During and after therapy the U2AF1 mutation progressed, whereas the JAK2 mutation could no longer be verified. The improvement in hematopoiesis might results from reduction of oxidative stress on hematopoietic progenitor cells or other unclear deferasirox-mediated effects, whereas the reason for the change in molecular genetic findings is unclear. It appears that deferasirox might have a modulating effect on JAK2-kinase mutations. However, further investigation of selective molecular suppression properties of deferasirox are warranted. © 2016 S. Karger GmbH, Freiburg.

This study evaluated the patterns of care and health care resource use (HCRU) in patients with metastatic squamous cell carcinoma of the head and neck (SCCHN) who received ≥3 lines of systemic therapy in the United Kingdom (UK). Oncologists (n = 40) abstracted medical records for patients with metastatic SCCHN who initiated third-line systemic therapy during 1 January 2011-30 August 2014 (n = 220). Patient characteristics, treatment patterns and SCCHN-related HCRU were summarised descriptively for the metastatic period; exploratory multivariable regression analyses were conducted on select HCRU outcomes. At metastatic diagnosis, most patients had an Eastern Cooperative Oncology Group performance status (PS) of 0/1 (95%). For patients with PS 0/1, the most common first-line treatment was cisplatin+5-fluorouracil (5-FU); docetaxel was the most common second- and third-line treatment. For patients with PS ≥ 2, the most common first-, second-, and third-line treatments were carboplatin+5-FU, cetuximab, and methotrexate, respectively. Most patients received supportive care during (85%) and after (89%) therapy. This study provides useful information, prior to the availability of immunotherapy, on patient characteristics, treatment patterns, HCRU, and survival in a real-world UK population with metastatic SCCHN receiving ≥3 lines of systemic therapy. Patterns of care and HCRU varied among patients with metastatic SCCHN; specific systemic therapies varied by patient PS. © 2018 Eli Lilly and Company.

Whether direct-acting antiviral (DAA) therapy can reduce liver fibrosis and steatosis in patients with chronic hepatitis C virus (HCV) infection remains unclear. We evaluated sequential changes in liver stiffness and steatosis using transient elastography (TE) and the TE-based controlled attenuation parameter (CAP) in patients with HCV who received DAA therapy. A total of 57 patients with HCV who received DAA therapy and achieved sustained virological response (SVR) were analyzed. Liver stiffness as evaluated with TE, steatosis as evaluated with CAP, and laboratory data were assessed before treatment (baseline), at end of treatment (EOT), 24 weeks after EOT (SVR24), and 48 weeks after EOT (SVR48). Alanine aminotransferase levels, corresponding to the presence of necroinflammatory activity, significantly decreased overall, with significant differences between baseline and EOT, EOT, and SVR24, and baseline and SVR48. However, alanine aminotransferase levels showed no significant changes between SVR24 and SVR48. Median (interquartile range) liver stiffness values at baseline, EOT, SVR24, and SVR48 were 8.3 (5.0-14.8), 7.4 (4.6-14.7), 5.3 (4.1-11.8), and 5.4 (4.0-13.4) kPa, respectively (baseline vs. EOT, P=0.044; EOT vs. SVR24, P=0.011; and SVR24 vs. SVR48, P=0.054). In patients with fatty liver (CAP≥236 dB/m, n=14), CAP values at baseline and SVR48 were 253 (245-278) and 229 (209-249) dB/m, respectively (P=0.020). Liver stiffness at SVR24 might reflect liver fibrosis in the patients who received DAA therapy and achieved SVR. In addition, liver steatosis reduces in the same cohort with fatty liver.

Purpose: To analyze the durability and toxicity of radiotherapeutic local ablative therapy (LAT) applied to extra-central nervous system (eCNS) disease progression in anaplastic lymphoma kinase-positive non-small cell lung cancer (NSCLC) patients. Methods and Materials: Anaplastic lymphoma kinase-positive NSCLC patients receiving crizotinib and manifesting ≤4 discrete sites of eCNS progression were classified as having oligoprogressive disease (OPD). If subsequent progression met OPD criteria, additional courses of LAT were considered. Crizotinib was continued until eCNS progression was beyond OPD criteria or otherwise not suitable for further LAT. Results: Of 38 patients, 33 progressed while taking crizotinib. Of these, 14 had eCNS progressionmore » meeting OPD criteria suitable for radiotherapeutic LAT. Patients with eCNS OPD received 1-3 courses of LAT with radiation therapy. The 6- and 12-month actuarial local lesion control rates with radiation therapy were 100% and 86%, respectively. The 12-month local lesion control rate with single-fraction equivalent dose >25 Gy versus ≤25 Gy was 100% versus 60% (P=.01). No acute or late grade >2 radiation therapy-related toxicities were observed. Median overall time taking crizotinib among those treated with LAT versus those who progressed but were not suitable for LAT was 28 versus 10.1 months, respectively. Patients continuing to take crizotinib for >12 months versus ≤12 months had a 2-year overall survival rate of 72% versus 12%, respectively (P<.0001). Conclusions: Local ablative therapy safely and durably eradicated sites of individual lesion progression in anaplastic lymphoma kinase-positive NSCLC patients receiving crizotinib. A dose–response relationship for local lesion control was observed. The suppression of OPD by LAT in patients taking crizotinib allowed an extended duration of exposure to crizotinib, which was associated with longer overall survival.« less

Comparison of early myocardial technetium-99m pyrophosphate uptake to early peaking of creatine kinase and creatine kinase-MB as indicators of early reperfusion in acute myocardial infarction

The value of technetium-99m pyrophosphate (Tc-99m-PYP) scintigraphy as an indicator of reperfusion 2.8 to 8 hours after the onset of symptoms of acute myocardial infarction was compared with the value of early peak creatine kinase (CK) and CK-MB release within 16 hours after the onset of symptoms. In 29 patients who received thrombolytic therapy, recanalization was seen (group 1) and in 7 it was not (group 2). In 23 patients (79%) in group 1 scintigraphic findings were positive and in all 7 in group 2 they were negative. In 15 patients (52%) in group 1 and 1 patient (14%) inmore » group 2, CK reached its peak level within 16 hours. In 20 patients (69%) in group 1 and 3 (43%) in group 2 the CK-MB level reached a peak within 16 hours. The sensitivity, specificity and predictive accuracy of positive results of early Tc-99m-PYP scintigraphy in predicting the reperfusion were 79%, 100% and 83%. These values are significantly higher than or similar to those of early peaking of CK and CK-MB release. In contrast to measurements of enzyme release, reperfusion data for Tc-99m-PYP scintigraphy are available immediately after thrombolytic therapy. Therefore, early Tc-99m-PYP scintigraphy (3 to 8 hours after onset of symptoms) is valuable as a noninvasive technique for early diagnosis of reperfusion.« less

The activity of palbociclib as a single agent in advanced breast cancer has not been extensively studied, with the only available clinical data limited to heavily pre-treated patients. Pre-clinical data suggests palbociclib may partially reverse endocrine resistance, though this hypothesis has not been evaluated in previous clinical studies. This phase II, open-label, multi-center study examined the activity of palbociclib monotherapy, as well as palbociclib given in combination with the same endocrine therapy (ET) that was received prior to disease progression, in post-menopausal women with moderately pre-treated, estrogen receptor-positive, HER2 negative advanced breast cancer. Eligible women with advanced disease which had progressed on one or two prior ETs were randomized 1:1 to receive either palbociclib alone, or palbociclib in combination with the ET as previously received. Primary endpoint was clinical benefit rate (CBR); secondary endpoints included progression-free survival (PFS). Between October 2012 and July 2016, a total of 115 patients were randomized. The CBR was 54% (95% CI 41.5 - 63.7) for combination therapy, and 60% (95% CI 47.8 - 72.9) for monotherapy. Median PFS was 10.8 months (95% CI 5.6 - 12.7) for combination therapy, and 6.5 months (95% CI, 5.4 to 8.5) for monotherapy (hazard ratio [HR] 0.69; 95% CI 0.4 - 1.1, exploratory P-value = 0.12). Exploratory analyses revealed the PFS advantage for combination therapy was seen in the subgroup of patients who received prior ET for >6 months (HR 0.53; 95% CI 0.3 - 0.9, exploratory P-value = 0.02), but not in those who received prior ET for ≤6 months. Palbociclib has clinical activity as a single agent in women with moderately pre-treated, oestrogen receptor-positive, HER2-negative advanced breast cancer. Palbociclib may have potential to reverse endocrine resistance in patients with a history of previous durable response to ET. NCT02549430.

People suffering from substance dependence suffer from various sexual dysfunctions and are at risk for indulging in various high-risk sexual behaviors and thus are vulnerable to acquire various infections such as HIV/AIDS and other sexually transmitted infections. The aim of the study was to evaluate the correlation between sexual dysfunction and high-risk sexual behavior in opioid-dependent men receiving buprenorphine and naltrexone maintenance therapy. Semi-structured questionnaire, brief male sexual functioning inventory and HIV-risk taking behavior scale was administered to a sample of 60 sexually active men, receiving buprenorphine (n = 30) and naltrexone (n = 30) maintenance therapy for opioid dependence. The main outcomes are correlation between severity of sexual dysfunction and HIV-risk taking behavior. The study results showed 83% of the men on buprenorphine and 90% on naltrexone reported at least one of the sexual dysfunction symptoms. There was a negative correlation between sexual dysfunction and HIV-risk taking behavior that suggest severe the dysfunction, higher the risk taking behavior. Significant correlation was present with overall sexual dysfunction and HIV-risk taking behavior (P = 0.028 and in naltrexone receiving group premature ejaculation versus HIV-risk taking behavior however, (P = 0.022, P < 0.05) there were no significant differences among both the groups except above findings. Conclusion was treatment is associated with sexual dysfunctions and HIV-risk taking behavior, which has clinical implication. Future research should explore this further using biochemical analyses.

The use of once-weekly exenatide in type 2 diabetes mellitus is well supported, but little is known about its effectiveness in type 1 diabetes. The objective of this study was to determine the clinical efficacy of once-weekly exenatide on glycemic control in patients with type 1 diabetes when added to basal-bolus insulin therapy. For this retrospective study, patients with type 1 diabetes, aged 18 years and older, receiving continuous subcutaneous insulin infusion, using a continuous glucose monitoring device or regularly measuring blood glucose levels and receiving 2 mg of exenatide once weekly for at least 3 months were included. Demographic information, glycated hemoglobin (A1C), body weight, body mass index, systolic and diastolic blood pressures, total daily insulin dose, basal and bolus insulin doses, 28-day continuous subcutaneous insulin infusion glucose average and incidence of hypoglycemia were collected at baseline and 3 months after beginning therapy with once-weekly exenatide. An electronic medical record search identified 11 patients with type 1 diabetes who met the inclusion criteria. Comparing baseline and 3 months after initiation of once-weekly exenatide revealed reductions of 0.6% in A1C (p=0.013), 3.7% in body weight (p=0.008), 1.7 kg/m(2) in body mass index (p=0.003), 13% in total daily insulin dose (p=0.011) and 9.3 units in bolus insulin dose (p=0.015). This study revealed that the addition of once-weekly exenatide to insulin therapy for type 1 diabetes patients leads to significant improvements in A1C, body weight, body mass index and insulin doses.

Neurological injuries can be divided into those with traumatic and nontraumatic causes. The largest groups are traumatic brain injury (TBI) and nontraumatic stroke. TBI patients may present with intracranial hemorrhages (contusions, or subdural or epidural hematomas). Strokes are ischemic or hemorrhagic. In all these disorders, thrombosis and hemostasis play a major role. Treatment aims to either cease bleeding and/or restore perfusion. We reviewed hemostatic and thrombolytic therapies in patients with neurological injuries by MEDLINE and EMBASE search using various key words for neurological disorders and hemostatic therapies restricted to English language and human adults. Review of articles fulfilling inclusion criteria and relevant references revealed that, in patients with ischemic stroke, intravenous thrombolytic therapy with recombinant tissue plasminogen activator within 4.5-5 hours after onset of symptoms improves clinical outcome. In contrast, there are no hemostatic therapies that are proven to improve clinical outcome of patients with hemorrhagic stroke or TBI. In patients with hemorrhagic stroke who use vitamin K antagonist or direct oral anticoagulants, there is evidence that specific reversal therapies improve hemostatic laboratory parameters but without an effect on clinical recovery. In patients with hemorrhagic stroke or TBI who use concomitant antiplatelet therapy, there is evidence for harm of platelet transfusion. In patients with aneurysmal subarachnoid hemorrhage, tranexamic acid was shown to reduce rebleeding rate without improving clinical outcome. The effects of tranexamic acid in patients with TBI are still under investigation. We conclude that, in patients with ischemic stroke, thrombolytic therapy improves outcome when given within 4.5-5 hours. In hemorrhagic stroke and TBI, most hemostatic therapies improved or corrected laboratory parameters but not clinical outcome. Currently, in several trials, the effects of tranexamic acid are

Skin reactions and pain are commonly reported side effects of radiation therapy (RT). To characterize RT-induced symptoms according to treatment site subgroups and identify skin symptoms that correlate with pain. A self-report survey-adapted from the MD Anderson Symptom Inventory and the McGill Pain Questionnaire--assessed RT-induced skin problems, pain, and specific skin symptoms. Wilcoxon Sign Ranked tests compared mean severity or pre- and post-RT pain and skin problems within each RT-site subgroup. Multiple linear regression (MLR) investigated associations between skin symptoms and pain. Survey respondents (N = 106) were 58% female and on average 64 years old. RT sites included lung, breast, lower abdomen, head/neck/brain, and upper abdomen. Only patients receiving breast RT reported significant increases in treatment site pain and skin problems (P < or = .007). Patients receiving head/neck/brain RT reported increased skin problems (P < .0009). MLR showed that post-RT skin tenderness and tightness were most strongly associated with post-RT pain (P = .066 and P = .122, respectively). Small sample size, exploratory analyses, and nonvalidated measure. Only patients receiving breast RT reported significant increases in pain and skin problems at the RT site while patients receiving head/neck/brain RT had increased skin problems but not pain. These findings suggest that the severity of skin problems is not the only factor that contributes to pain and that interventions should be tailored to specifically target pain at the RT site, possibly by targeting tenderness and tightness. These findings should be confirmed in a larger sampling of RT patients.

and Overview. In 2005, the American Dental Association (ADA) Council on Scientific Affairs convened an expert panel to develop clinical recommendations for dentists treating patients who are receiving oral bisphosphonate therapy. The Journal of the American Dental Association published the resulting report in 2006. This 2008 advisory statement is the first of projected periodic updates of the 2006 clinical recommendations. This 2008 advisory statement concludes, on the basis of a review of the current literature, that for patients receiving bisphosphonate therapy, the risk of developing bisphosphonate-associated osteonecrosis (BON) of the jaw apparently remains low. It also newly concludes that current screening and diagnostic tests are unreliable for predicting a patient's risk of developing the condition. This statement updates the 2006 recommendations regarding general dentistry, management of periodontal diseases, implant placement and maintenance, oral and maxillofacial surgery, endodontics, restorative dentistry and prosthodontics, and orthodontics.

Inadvertent exaggerated anticoagulation following use of bismuth subsalicylate in an enterally fed patient receiving warfarin therapy.

2013-12-01

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.

To determine whether fertility preservation with ovarian stimulation (OS) results in treatment delay in breast cancer (BC) patients receiving neoadjuvant therapy (NAT). This is a retrospective study of women screened for the prospective neoadjuvant ISPY2 trial at the University of California San Francisco. All patients were <43, had stage II-III BC, and received neoadjuvant therapy. Time to initiation of NAT was compared between women who underwent OS (STIM) and women who did not (control). Patient and tumor characteristics, as well as oncologic outcomes, were compared between STIM and control groups. 82 patients were included (34 STIM and 48 control). STIM patients were overall younger (mean = 35 vs. 36.9 years old, p = 0.06), and more likely to be childless (79.4 vs 31.2%, p < 0.0001) than controls. Mean time from diagnosis to initiation of NAT was 40 days, with no significant difference between STIM and control groups (mean 39.8 days vs 40.9 days, p = 0.75). Mean time from diagnosis to fertility consultation was 16.3 days. With median follow-up of 79 months, 16 (19.5%) patients have recurred or died from BC. Rates of pCR, recurrence, and death were similar in both groups. Six of 34 STIM patients have undergone embryo transfer, resulting in one patient with two live births. Fertility preservation with OS can be performed in the neoadjuvant setting without delay in initiation of systemic therapy and should be discussed with all early-stage BC patients of reproductive age.

2013-03-01

In an earlier continuous glucose monitoring (CGM)-based study, we reported that sitagliptin not only reduced 24-h mean glucose levels but also suppressed postprandial glucose increases, thus reducing the range of glycemic fluctuations in type 2 diabetes patients. In this study, we investigated whether sitagliptin might provide similar benefits in type 2 diabetes patients receiving insulin therapy by using CGM. The study included a total of 13 type 2 diabetes patients in whom stable glycemic control had been achieved after admission for glycemic control. Insulin regimens used included long-acting insulin preparations once daily in four patients and biphasic insulin preparations twice daily in nine, with the daily insulin dose being 19.0±12.7 U. During the CGM-based study, the patients were given insulin therapy alone on Days 1 and 2 and were given sitagliptin 50 mg/day as add-on treatment on Days 3-6, with their daily insulin doses maintained. The add-on treatment with sitagliptin led to significant decreases in 24-h mean glucose levels and SDs of 288 glucose levels measured by CGM for 24 h, as well as in the indices for magnitude of glucose variability and proportion of time in hyperglycemia, compared with insulin therapy alone (P<0.01), whereas there was no significant change seen in regard to the proportion of time in hypoglycemia with or without add-on treatment with sitagliptin. This CGM-based study clearly demonstrated that insulin therapy alone, whether with long-acting or biphasic insulin preparations, does not provide adequate glycemic control in type 2 diabetes patients. In contrast, add-on sitagliptin was shown to narrow the range of 24-h glucose fluctuations in these patients, suggesting that add-on treatment with sitagliptin is effective for postprandial glucose control in type 2 diabetes patients receiving insulin therapy.

CENTRAL SEROUS CHORIORETINOPATHY IN POSTMENOPAUSAL WOMEN RECEIVING EXOGENOUS TESTOSTERONE.

Conway, Mandi D; Noble, Jason A; Peyman, Gholam A

2017-01-01

Central serous chorioretinopathy (CSR) is a serous detachment of the neurosensory retina commonly associated with male sex, Type-A personality and corticosteroid use. Exogenous administration of androgens and development of CSR in men has been reported. Only one case of CSR in a postmenopausal woman receiving exogenous androgen therapy has been reported. The authors describe three cases of chronic CSR in postmenopausal women receiving exogenous testosterone therapy. Diagnosis was based on characteristic clinical, fluorescein angiographic, and optical coherence tomography findings. The three women were being treated with exogenous testosterone and progesterone therapy for symptoms of menopause and libido loss. Average age at presentation was 54.7 years (53-56 years), average duration of exogenous androgen use was 61 months (36-87 months), with average 19.7-month follow-up. Resolution of symptoms seemed correlated with cessation of androgen use despite treatment with oscillatory photodynamic therapy and intravitreal pharmacotherapy with antivascular endothelial growth factor agents. Exogenous testosterone is increasingly prescribed for menopausal symptoms and libido loss. Treatment with oscillatory photodynamic therapy, supplemental bevacizumab intravitreal pharmacotherapy, and cessation of exogenous androgen therapy was successful in three cases of chronic, therapy-resistant CSR. Ophthalmologists should inquire about androgen usage in patients who present with CSR, especially in the setting of therapy resistance.

Objective: To investigate the heart rate control situation of chronic heart failure (CHF) patients who received cardiovascular implantable electronic device (CIED) therapy, and to assess the heart rate control efficacy by optimized medication adjustment. Methods: We performed a perspective study in heart failure with reduced left ventricular ejection fraction (HFrEF) patients who received CIED according to guideline recommendations, patients were enrolled from January 2012 to January 2017. Resting heart rate (RHR) recorded by electrocardiogram after 10 minutes' rest and medication usage within 1 month were recorded at baseline. RHR less than 70 beats per minute (bpm) was regarded as well controlled. β-receptor blockers and (or) ivabradine would be added in patients whose RHR were over 70 bpm. RHR after optimized medication adjustment was recorded during follow-up period. Results: One hundred and fifty patients were included in this study with average RHR (80.6±11.9) bpm. RHR was<70 bpm in 27.3% (41/150) patients at baseline and β-receptor blockers was underused in 80.7% patients (88/109) whose RHR was>70 bpm. The overall RHR decreased to (73.1±10.4) bpm and percent of patients with RHR<70 bpm increased to 70.0% (105/150) after up-titration of β-receptor blockers compared to baseline (χ 2 =52.958, P< 0.001). Ivabradine was added in the rest 45 patients and RHR was<70 bpm in 43 out of 45 patients after ivabradine use. The overall RHR decreased to (67.1±2.7) bpm and percent of RHR<70 bpm significantly increased to 98.7% (148/150) (χ 2 =44.504, P< 0.001 vs. up-titration of β-receptor blockers only). Conclusion: RHR in CHF patients who received CIED therapy is not ideally controlled in this patient cohort, individual up-titration ofβ-receptor blockers and ivabradine use may help to optimize RHR in these patients.

The purpose of the study was to determine the effect of type 2 diabetes mellitus (T2DM) on outcomes and toxicities among men with localized prostate cancer receiving definitive radiation therapy. We performed a retrospective review of 3217 patients, from 1998 to 2013, subdivided into 5 subgroups: (I) no T2DM; (II) T2DM receiving oral antihyperglycemic agent that contains metformin, no insulin; (III) T2DM receiving nonmetformin oral agent alone, no insulin; (IV) T2DM receiving any insulin; and (V) T2DM not receiving medication. Outcome measures were overall survival, freedom from biochemical failure (BF), freedom from distant metastasis, cancer-specific survival, and toxicities. Kaplan-Meier analysis, log rank tests, Fine and Gray competing risk regression (to adjust for patient and lifestyle factors), Cox models, and subdistribution hazard ratios (sHRs) were used. Of the 3217 patients, 1295 (40%) were low-risk, 1192 (37%) were intermediate-risk, and 652 (20%) were high risk. The group I to V distribution was 81%, 8%, 5%, 3%, and 4%. The median dose was 78 Gy, and the median follow-up time was 50 (range, 1-190) months. Group V had increased mortality (sHR, 2.1; 95% confidence interval [CI], 0.66-1.54), BF (sHR, 2.14; 0.88-1.83), and cause-specific mortality (sHR, 3.87; 95% CI, 1.31-11). Acute toxicities were higher in group IV versus group I (genitourinary: 38% vs. 26%; P = .01; gastrointestinal: 21% vs. 5%; P = 001). Late toxicities were higher in groups IV and V versus group I (12%-14% vs. 2%-6%; P < .01). Men with T2DM not receiving medication and men with T2DM receiving insulin had worse outcomes and toxicities compared to other patients. Copyright © 2016 Elsevier Inc. All rights reserved.

To determine if short-duration anesthesia (propofol and remifentanil) can blind subjects to the provision or withholding of spinal manipulative therapy (SMT). Placebo control. Day-procedure ward, University of Alberta Hospital. Human subjects with uncomplicated low back pain (LBP) (n=6). In each subject, propofol and remifentanil were administered intravenously. Once unconsciousness was achieved (3-5min), subjects were placed in a lateral recumbent position and then randomized to either a control group (n=3) or an experimental group (with SMT, n=3); subjects received a single SMT to the lumbar spine. Subjects were given a standardized auditory and visual cue and then allowed to recover from anesthesia in a supine position (3-5min). Before anesthesia and 30 minutes after recovery, a blinded evaluator asked each subject to quantify their LBP by using an 11-point scale. This same evaluator then assessed the ability of each subject to recall specific memories while under presumed anesthesia including events related to treatment and specific auditory and visual cues. In either the experimental or control group, subjects could not recall any event while under anesthesia. Some SMT subjects reported pain reduction greater than the minimally important clinical difference and greater than control subjects. No adverse events were reported. Short-duration, low-risk general anesthesia can create effective blinding of subjects to the provision or withholding of SMT. An anesthetic blind for SMT subjects solves many, if not all, problems associated with prior SMT blinding strategies. Although further studies are needed to refine this technique, the potential now exists to conduct the first placebo-controlled randomized controlled trial to assess SMT efficacy.

There are little prevalence data in the literature on nonadherence to outpatient antiemetic regimens for prophylaxis of chemotherapy-induced nausea and vomiting (CINV). It is unclear whether adherence with outpatient antiemetic regimens is associated with better CINV control. Our previous survey research supports the work of clinical pharmacists in collaborative practice with medical oncologists in improving adherence with antiemetic therapy in women undergoing highly emetic chemotherapy for breast cancer. To (a) evaluate the impact of adherence to delayed antiemetics (days 2-4 following anthracycline-based chemotherapy) on CINV control in breast cancer patients after anthracycline-based chemotherapy and (b) identify patient-related factors associated with nonadherence to delayed antiemetics. A single-center, prospective, observational study was conducted from December 2006 to January 2011 in breast cancer patients receiving anthracycline-based chemotherapy (doxorubicin or epirubicin) and antiemetics at the National Cancer Centre Singapore (NCCS), the largest ambulatory cancer center in Singapore. Included patients were aged 21 years or older with confirmed diagnoses of breast cancer and receiving anthracycline-containing chemotherapy with antiemetics. Patients were excluded if they (a) were diagnosed with intestinal obstruction or received concurrent radiotherapy that predisposed them to nausea and vomiting, (b) had vomited in the 24 hours preceding chemotherapy, or (c) had brain metastases that would impair their judgment. Patients documented in a standardized diary their emesis events, severity of nausea, use of rescue therapy with metoclopramide, and compliance with dose instructions for antiemetic drug therapy for 5 days: day 1 was the day of chemotherapy and first day of antiemetic therapy, and day 5 was the day after completion of delayed antiemetic therapy (days 2-4). Three definitions were used to describe the CINV outcomes: (a) complete response (no

Patients with human immunodeficiency virus type 1 (HIV-1) infection are at high risk of developing Epstein-Barr virus (EBV)-associated lymphoma. However, little is known of the EBV DNA loads in patients receiving highly active antiretroviral therapy (HAART). Using a real-time quantitative polymerase chain reaction assay, we demonstrated that significantly more HIV-1-infected patients receiving HAART than HIV-1-uninfected volunteers had detectable EBV DNA in blood (57 [81%] of 70 vs. 11 [16%] of 68 patients; P=.001) and saliva (55 [79%] of 68 vs. 37 [54%] of 68 patients; P=.002). The mean EBV loads in blood and saliva samples were also higher in HIV-1-infected patients than in HIV-1-uninfected volunteers (P=.001). The frequency of EBV detection in blood was associated with lower CD4+ cell counts (P=.03) among HIV-1-infected individuals, although no differences were observed in the EBV DNA loads in blood or saliva samples in the HIV-1-infected group. Additional studies are needed to determine whether EBV-specific CD4+ and CD8+ cells play a role in the pathogenesis of EBV in HIV-1-infected patients receiving HAART.

Purpose To ascertain whether single nucleotide polymorphisms (SNPs) in the Vascular Endothelial Growth factor (VEGFA), Complement Factor H (CFH), and LOC387715 genes could predict outcome to anti-VEGF therapy for patients with age related macular degeneration (AMD). Methods Patients with “wet” AMD were identified by chart review. Baseline optical coherence tomography (OCT) and visual acuity (VA) data, and at least 6 months of clinical follow up after 3 initial monthly injections of bevacizumab or ranibizumab were required for inclusion. Based on OCT and VA, patients were categorized into two possible clinical outcomes: (a) responders and (b) non-responders. DNA was extracted from saliva and genotyped for candidate SNPs in the VEGFA, LOC387715, and CFH genes. Clinical outcomes were statistically compared to patient genotypes. Results 101 patients were recruited, and one eye from each patient was included in the analysis. 97% of samples were successfully genotyped for all SNPs. We found a statistically significant association between the LOC387715 A69S TT genotype and outcome based on OCT. Conclusion Genetic variation may be associated with outcome in patients receiving anti-VEGF therapy. PMID:24143065

Five to 10% of women with newly diagnosed breast cancer have synchronous metastases (de novo stage IV). A further 20% will develop metastases during follow-up (recurring stage IV). We compared the clinical outcomes of women with HER2-positive metastatic breast cancer (MBC) receiving first-line trastuzumab-based therapy according to type of metastatic presentation. Retrospective analysis of 331 MBC patients receiving first-line trastuzumab-based treatment. Response rates (RR) were compared by the chi-square test. Time-to progression (TTP) and overall survival (OS) curves were compared by the log-rank test. Cox-proportional hazards models were used to study predictors of PFS and OS, including the type of metastatic presentation. Seventy-seven patients (23%) had de novo stage IV disease. Forty-six of these patients underwent surgery of the primary ("de novo/surgery"). Response rates to first-line trastuzumab-based therapy and median progression-free survival did not differ in patients with "recurring", "de novo/surgery" and "de novo" without surgery ("de novo/no surgery) stage IV breast cancer. However, women with "de novo/surgery" stage IV breast cancer had the longest median OS (60 months), and those with "de novo/no surgery" stage IV breast cancer the shortest (26 months). For women with recurring metastatic breast cancer median OS was 40 months (overall log-rank test, p < 0.01). Multivariate analysis confirmed these findings. Our analysis shows that response rates and PFS to first-line trastuzumab-based therapy do not differ significantly between de novo and recurring stage IV, HER2 positive breast cancer. The observed difference in OS favoring women with de novo stage IV disease submitted to surgery of the primary tumor could be the result of a selection bias. Copyright © 2013 Elsevier Ltd.

Daptomycin, a cyclic lipopeptide antibiotic, and 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase inhibitors (statins) are commonly administered in the inpatient setting and are associated with creatine phosphokinase (CPK) elevations, myalgias, and muscle weakness. Safety data for coadministration of daptomycin with statins are limited. To determine the safety of coadministration of daptomycin with statin therapy, a multicenter, retrospective, observational study was performed at 13 institutions in the Southeastern United States. Forty-nine adult patients receiving statins concurrently with daptomycin were compared with 171 patients receiving daptomycin without statin therapy. Detailed information, including treatment indication and duration, infecting pathogen, baseline and subsequent CPK levels, and presence of myalgias or muscle complaints, was collected. Myalgias were noted in 3/49 (6.1%) patients receiving combination therapy compared with 5/171 (2.9%) of patients receiving daptomycin alone (P = 0.38). CPK elevations of >1,000 U/liter occurred in 5/49 (10.2%) patients receiving combination therapy compared to 9/171 (5.3%) patients receiving daptomycin alone (P = 0.32). Two of five patients experiencing CPK elevations of >1,000 U/liter in the combination group had symptoms of myopathy. Three patients (6.1%) discontinued therapy due to CPK elevations with concurrent myalgias in the combination group versus 6 patients (3.5%) in the daptomycin-alone group (P = 0.42). CPK levels and myalgias reversed upon discontinuation of daptomycin therapy. Overall musculoskeletal toxicity was numerically higher in the combination group but this result was not statistically significant. Further prospective study is warranted in a larger population.

The aim of this study was to observe the influence of Kampo therapy on latent chronic fatigue of patients with chronic diseases. One hundred and seventy-three (173) consecutive patients with chronic diseases came to our department for the first time. This was a prospective study. Patients were divided into two groups: a chronic fatigue group (CFG) and a nonchronic fatigue group (NCFG). Based on Kampo diagnosis, both groups were prescribed Kampo formulae as an extract or decoction for 12 weeks. By using questionnaires, patients were assessed concerning their physical and mental types of fatigue, their sleep situation, and their attitude toward work or housekeeping, both before and after 12 weeks of treatment, according to Kampo diagnosis. The mental fatigue, physical fatigue, and sleep scores of both groups, and the work score of CFG, were decreased. The rate of reduction of the fatigue score was significantly greater in CFG than in NCFG. The factor responsible for this difference in fatigue score was physical fatigue. A reduction of the perception of chronic fatigue was observed in patients receiving 12 weeks of Kampo therapy.

Aprepitant, a neurokinin-1 receptor antagonist, in combination with 5 HT-3 antagonist and dexamethasone is recommended in adults receiving moderately and highly emetogenic chemotherapy to reduce chemotherapy-induced vomiting (CIV). Data for use of aprepitant in children is limited and hence aprepitant is not recommended by Pediatric Oncology Group of Ontario guidelines for prevention of CIV in children <12 years. A randomized, double-blind, placebo-controlled trial was conducted at a single center in chemotherapy naïve children (5-18 years) receiving highly emetogenic chemotherapy. All patients received intravenous ondansetron (0.15 mg/kg) and dexamethasone (0.15 mg/kg) prior to chemotherapy followed by oral ondansetron and dexamethasone. Patients randomly assigned to aprepitant arm received oral aprepitant (15-40 kg = days 1-3, 80 mg; 41-65 kg = day 1, 125 mg and days 2-3, 80 mg) 1 h before chemotherapy. Control group received placebo as add-on therapy. Primary outcome measure was the incidence of acute moderate to severe vomiting, which was defined as more than two vomiting episodes within 24 h after the administration of the first chemotherapy dose until 24 h after the last chemotherapy dose in the block. Complete response (CR) was defined as absence of vomiting and retching during the specified phase. Of the 96 randomized patients, three were excluded from analysis; 93 patients were analyzed (50 in aprepitant arm and 43 in placebo arm). Acute moderate and severe vomiting was reported in 72 % patients receiving placebo and 38 % patients receiving aprepitant (p = 0.001). Complete response rates during acute phase were significantly higher in aprepitant arm (48 vs. 12 %, p < 0.001). No major adverse effects were reported by patients/guardians. This double-blind, randomized, placebo-controlled trial shows that aprepitant significantly decreases the incidence of CIV during acute phase when used as an add-on drug with ondansetron and dexamethasone in children

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). 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. 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. At a mean follow-up period of 15 months, DAPT + VKA was associated with significantly lower risk of stroke, ST, and all-cause mortality in AF patients after PCI-S compared with

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.

The safety and outcomes of intravenous thrombolysis (IVT) to stroke patients via telestroke (TS) is similar to those presenting to stroke centers. Little is known on the accuracy of TS diagnosis among those receiving IVT. We sought to compare the rate of patients receiving IVT with diagnosis of ischemic stroke as opposed to stroke mimic (SM) in our TS network to those who presented to our comprehensive stroke center (CSC). Consecutive patients receiving IVT between August 2014 and June 2015 were identified at our CSC and TS network. We compared rates of SM, post-IVT symptomatic intracerebral hemorrhage (sICH), in-hospital mortality, and discharge destination. We evaluated 131 receiving IVT were included in the analysis. Rates of SM receiving IVT were similar (CSC 12% versus 7% TS, p=0.33). Four stroke patients experienced sICH or in-hospital mortality; neither were found among SM patients. Discharge destination was similar between stroke and SM patients (p=0.9). SM patients had higher diagnoses of migraine (p=0.05) and psychiatric illness (p<0.01). The accuracy of diagnosing stroke in IVT-eligible patients evaluated via TS is similar to evaluations at our CSC. Continued efforts should be made to minimize exposure of SM patients to IVT in both settings. Copyright © 2016 Elsevier B.V. All rights reserved.

Iodinated contrast media (Xenetix®, Ultravist®, Omnipaque®, Visipaque® and Iomeron®) used for computed tomography (CT) may decrease fibrinolysis by recombinant tissue plasminogen activator (rt-PA). We hypothesized that receiving iodinated contrast media before rt-PA may impair thrombolysis as measured by a new model system. Whole blood from Wistar Kyoto rats (n = 10) was obtained and allowed to form blood clots. Thrombolysis was performed by placing individually the prepared clots into 15 mL tubes and adding 5 mL saline buffer, 100μg rt-PA and a different contrast media; adjusting the quantity of iodine to either 30 mg or 60 mg. The thrombolytic efficacy was quantified by measuring the optical density (OD415) of the supernatant at different time points, namely at 0, 30, 60, and 90 min. There was a significant decrease in clot lysis efficiency observed in presence of iodine containing contrast media comparing to positive control group. Moreover, when the quantity of iodine was increased from 30 mg to 60 mg; the dissolution rate downturned with additional ∼50%. In conclusion, our study suggests that high dose of iodine potentially could negatively affect the efficiency of the thrombolytic therapy performed by rt-PA.

Thrombocytopenia, a serious complication of myelosuppressive chemotherapy in cancer patients, is managed with platelet transfusions until recovery of platelet counts. However, children receiving chemotherapy can rarely develop immune thrombocytopenia (ITP) that is refractory to transfused platelets. This limits the ability to achieve adequate platelet counts and administer further myelosuppressive chemotherapy safely, especially if first-line ITP therapy is ineffective. We report 2 cases of intravenous immunoglobulin refractory ITP in children receiving chemotherapy for high-risk neuroblastoma. ITP was successfully treated with the thrombopoietin-receptor-agonist romiplostim, allowing safe and timely continuation of antineuroblastoma therapies in these high-risk patients.

In 2011, family planning (FP) services were integrated at Martin Preuss Centre (MPC), in urban Lilongwe, Malawi. To date, no previous study evaluated pregnancy rates among HIV-positive women after the integration of FP services into HIV care at the facility. In this study, we investigated whether integration of FP services into HIV clinical care led to increased use of contraceptives and decreased pregnancy rates. This was a retrospective cohort analysis of HIV-positive women from 15 to 49 years of age who accessed antiretroviral therapy (ART) services at MPC. Ascertainment of FP needs, contraceptive methods and pregnancy status were done at ART initiation, and at each ART follow-up visit. Women were offered a wide range of contraceptive methods. Outcomes of interest were contraceptive use and rate of pregnancy. Incident pregnancy was ascertained through patient self-reports during clinic consultation. Trends of contraceptive use and pregnancy rates were analyzed using chi-square (χ2). A total of 10,472 women were included in the analysis and contributed 15,700 person-years of observation. Contraceptive use among all women receiving ART increased from 28% in 2012 to 62% in 2016 (p < 0.001). A total of 501 pregnancies occurred, including 13 multiple pregnancies, resulting in an overall pregnancy rates of 3.2 per 100 person-years. Rates of pregnancy decreased from 6.8 per 100 person-years in 2012 to 1.3 per 100 person-years in 2016 (p < 0.001). Integration of FP services into HIV care resulted in increased contraceptive use and, subsequently, decreased pregnancy rates in women receiving ART. HIV programs should consider offering FP services to women who are receiving ART.

Salt intake is recognized as an important risk factor for hypertension in the general population. On the other hand, the availability of various classes of antihypertensive drugs means that it is generally not considered crucial to control the salt intake of hypertensive patients. In this study, we evaluated whether blood pressure (BP) was correlated with 24-hour salt intake in patients receiving antihypertensive therapy. A total of 1496 consecutive participants undergoing health screening examinations were recruited. Subjects were divided into two groups according to their antihypertensive medications checked on prescriptions: 1005 subjects without antihypertensive therapy (untreated subjects) and 491 subjects with antihypertensive therapy (treated subjects). The 24-hour urinary sodium excretion (24h-uNa), a surrogate marker for daily salt intake, was estimated with the formula proposed by Tanaka et al. in 2002. Univariate analysis indicated that 24h-uNa was positively correlated with the systolic BP of both untreated and treated subjects. This was confirmed by multiple linear regression analysis after adjustment for confounding factors (untreated subjects: partial regression coefficient β=1.45 ± 0.26, p<0.001; treated subjects: β=0.75 ± 0.27, p=0.01). Salt intake was also correlated with the pulse pressure in both treated subjects (β=0.55 ± 0.24, p=0.02) and untreated subjects (β=0.93 ± 0.19, p<0.001). These results suggest the importance of reducing salt intake in hypertensive patients on pharmacotherapy, as well as in the general population. Further studies of hypertensive patients employing 24-h urine collection are warranted to confirm the present findings. Copyright © 2015 European Federation of Internal Medicine.

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.

Left ventricular ejection fraction may not be useful as an end point of thrombolytic therapy comparative trials.

In the era of comparative and adjunctive trials in reperfusion therapy, the need to develop alternative end points for mortality reduction is clear. Left ventricular ejection fraction, which has been commonly used as a surrogate, is problematic due to missing values, technically inadequate studies, and lack of correlation with mortality results in controlled reperfusion trials performed to date. In this paper, we present a composite clinical end point that includes, in order, severity of adverse outcome death, hemorrhagic stroke, nonhemorrhagic stroke, poor ejection fraction (less than 30%), reinfarction, heart failure, and pulmonary edema. Such a composite index may be useful to detect true therapeutic benefit in reperfusion trials without necessitating greater than 20-30,000 patient enrollment.

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.

 The objective of this study is to measure the impact of a five-step implementation process for an acute myocardial infarction (AMI) clinical pathway (CPW) on thrombolytic administration in rural emergency departments.  Cluster randomised controlled trial.   Six rural Victorian emergency departments participated.   The five-step CPW implementation process comprised (i) engaging clinicians; (ii) CPW development; (iii) reminders; (iv) education; and (v) audit and feedback. The impact of the intervention was assessed by measuring the proportion of eligible AMI patients receiving a thrombolytic and time to thrombolysis and electrocardiogram. Nine hundred and fifteen medical records were audited, producing a final sample of 108 patients eligible for thrombolysis. There was no significant difference between intervention and control groups for median door-to-needle time (29 mins versus 29 mins; P = 0.632), proportion of those eligible receiving a thrombolytic (78% versus 84%; P = 0.739), median time to electrocardiogram (7 mins versus 6 mins; P = 0.669) and other outcome measures. Results showed superior outcome measures than other published studies. The lack of impact of the implementation process for a chest pain CPW on thrombolytic delivery or time to electrocardiogram in these rural hospitals can be explained by a ceiling effect in outcome measures but was also compromised by the small sample. Results suggest that quality of AMI treatment in rural emergency departments (EDs) is high and does not contribute to the worse mortality rate reported for AMIs in rural areas. © 2012 The Authors.

407 cases of unresectable hepatocellular carcinoma (HCC) occurring from 1970 to March 1985, including 107 cases receiving conservative therapy, 176 cases receiving one-shot therapy and 124 cases receiving transcatheter arterial embolization (TAE) therapy, were studied and the efficacy of chemotherapy was compared with that of TAE therapy. The results were as follows; One-year survival rate was 2.8% with a median survival time of 1.3 months in conservative therapy. In the 176 cases of one-shot therapy, one-year survival rate was 21.0%, two-year 6.8% and three-year 2.3% and the median survival time was 4.8% months. In 120 cases of one-shot therapy which were compatible with criteria for one-shot injection of anticancer drugs via the hepatic artery for HCC, one-year survival rate was 30%. However the rate was 1.8% in 56 cases which were not compatible with the criteria. In 37 cases in which Mitomycin C (MMC) and Adriamycin (ADR) were administered alternately, one-year survival rate was 41.7%, two-year 16.1% and three-year 4.3%. The highest survival rate was obtained by TAE therapy. One-year survival rate was 66.9%, two-year 33.8% and three-year 28.9%. Decrease of AFP after therapy was noted in 42.4% of cases given one-shot therapy and in 95.2% of cases given TEA therapy. The results suggest that alternate administration of anticancer agents produces good chemotherapeutic effects and that the best life-prolongation is obtained by TAE therapy.

Whether direct-acting anti-viral therapy can reduce liver fibrosis and steatosis in patients with chronic hepatitis C virus (HCV) infection is unclear. To evaluate changes in liver stiffness and steatosis in patients with HCV who received direct-acting anti-viral therapy and achieved sustained virological response (SVR). A total of 198 patients infected with HCV genotype 1 or 2 who achieved SVR after direct-acting anti-viral therapy were analysed. Liver stiffness as evaluated by magnetic resonance elastography, steatosis as evaluated by magnetic resonance imaging-determined proton density fat fraction (PDFF), insulin resistance, and laboratory data were assessed before treatment (baseline) and at 24 weeks after the end of treatment (SVR24). Alanine aminotransferase and homeostatic model assessment-insulin resistance levels decreased significantly from baseline to SVR24. Conversely, platelet count, which is inversely associated with liver fibrosis, increased significantly from baseline to SVR24. In patients with high triglyceride levels (≥150 mg/dL), triglyceride levels significantly decreased from baseline to SVR24 (P = 0.004). The median (interquartile range) liver stiffness values at baseline and SVR24 were 3.10 (2.70-4.18) kPa and 2.80 (2.40-3.77) kPa respectively (P < 0.001). The PDFF values at baseline and SVR 24 were 2.4 (1.7-3.4)% and 1.9 (1.3-2.8)% respectively (P < 0.001). In addition, 68% (19/28) of patients with fatty liver at baseline (PDFF ≥5.2%; n = 28) no longer had fatty liver (PDFF <5.2%) at SVR24. Viral eradication reduces both liver stiffness and steatosis in patients with chronic HCV who received direct-acting anti-viral therapy (UMIN000017020). © 2018 John Wiley & Sons Ltd.

Sinusoidal obstruction syndrome (SOS) is one of the life-threatening complications caused by endothelial damage to the hepatic sinusoids after hematopoietic stem cell transplantation. However, a satisfactory treatment for SOS has not yet been established. Defibrotide has anti-thrombotic, anti-ischemic, anti-inflammatory, and thrombolytic properties without systemic anticoagulant effects. We treated eight post-transplant SOS patients with defibrotide. Three patients responded to the therapy and the initial response was observed within a week. In addition to the improvement of liver function, rapid recovery of response to diuretic drugs followed by the improvement of renal function was observed. All of the five patients with respiratory dysfunction died despite administration of defibrotide, suggesting that early treatment might lead to better outcomes. There were no severe adverse effects directly due to defibrotide administration. Defibrotide seems to be a promising treatment for SOS, and the initiation of a clinical study in Japan would be important.

To evaluate repeat surfactant therapy for the treatment of respiratory failure associated with postsurfactant slump in extremely low birth weight infants (ELBW) by characterizing the population of premature infants who develop postsurfactant slump and measuring their response to a secondary course of surfactant therapy. A retrospective analysis of a cohort of all patients admitted over a 3-year period with birth weights <1000 g (ELBW infants). Information was collected by chart review and the patients were categorized into three distinct groups for analysis. Initial surfactant only, patients who received surfactant replacement therapy only for respiratory distress syndrome (RDS); repeat surfactant, patients who received both initial surfactant replacement for RDS and repeat surfactant therapy for postsurfactant slump (defined as respiratory failure after 6 days of age), and no surfactant, patients in whom no surfactant was ever administered. A respiratory severity score (RSS) was used to measure the severity of lung disease and response to surfactant therapy. Over 3 years, there were 165 ELBW infants who could develop postsurfactant slump and be eligible for repeat surfactant therapy. There were 39 infants who never received any surfactant therapy estimated gestational age (EGA) 27.7 +/- 1.7, birth weight 856 +/- 109 g) either at birth or after 6 days of life. There were 126 patients treated for RDS with initial surfactant replacement therapy (EGA 25.6 +/- 1.9 weeks, birth weight 713 +/- 179 g). Out of these RDS patients, 101 improved with an initial course of surfactant therapy (EGA 26 +/- 1.8, birth weight 751 +/- 143 g), but 25 (20% of the patients with RDS) developed postsurfactant slump and received a repeat course of surfactant therapy (EGA 24.7 +/- 1.2, birth weight 647 +/- 120 g). The repeat surfactant group (postsurfactant slump) was significantly more premature and had significantly lower birth weights compared to both the initial surfactant only group

Objective: Framed in the patients’ engagement perspective, the current study aims to determine the effects of group music therapy in addition to drug care in comparison with drug care in addition to other non-expressive group activities in the treatment of psychiatric outpatients. Method: Participants (n = 27) with ICD-10 diagnoses of F20 (schizophrenia), F25 (schizoaffective disorders), F31 (bipolar affective disorder), F32 (depressive episode), and F60 (specific personality disorders) were randomized to receive group music therapy plus standard care (48 weekly sessions of 2 h) or standard care only. The clinical measures included dosages of neuroleptics, benzodiazepines, mood stabilizers, and antidepressants. Results: The participants who received group music therapy demonstrated greater improvement in drug dosage with respect to neuroleptics than those who did not receive group music therapy. Antidepressants had an increment for both groups that was significant only for the control group. Benzodiazepines and mood stabilizers did not show any significant change in either group. Conclusion: Group music therapy combined with standard drug care was effective for controlling neuroleptic drug dosages in adult psychiatric outpatients who received group music therapy. We discussed the likely applications of group music therapy in psychiatry and the possible contribution of music therapy in improving the psychopathological condition of adult outpatients. In addition, the implications for the patient-centered perspective were also discussed. PMID:27774073

The primary aim was to investigate the comparative effects of massage therapy and exercise therapy on patients with multiple sclerosis. The secondary aim was to investigate whether combination of both massage and exercise has an additive effect. Randomized controlled pilot trial with repeated measurements and blinded assessments. Local Multiple Sclerosis Society. A total of 48 patients with multiple sclerosis were randomly assigned to four equal subgroups labelled as massage therapy, exercise therapy, combined massage-exercise therapy and control group. The treatment group received 15 sessions of supervised intervention for five weeks. The massage therapy group received a standard Swedish massage. The exercise therapy group was given a combined set of strength, stretch, endurance and balance exercises. Patients in the massage-exercise therapy received a combined set of massage and exercise treatments. Patients in the control group were asked to continue their standard medical care. Pain, fatigue, spasticity, balance, gait and quality of life were assessed before and after intervention. Massage therapy resulted in significantly larger improvement in pain reduction (mean change 2.75 points, P = 0.001), dynamic balance (mean change, 3.69 seconds, P = 0.009) and walking speed (mean change, 7.84 seconds, P = 0.007) than exercise therapy. Patients involved in the combined massage-exercise therapy showed significantly larger improvement in pain reduction than those in the exercise therapy (mean change, 1.67 points, P = 0.001). Massage therapy could be more effective than exercise therapy. Moreover, the combination of massage and exercise therapy may be a little more effective than exercise therapy alone.

This study focused on the predictors of therapy dropout in a naturalistic sample of patients with borderline pathology receiving dialectical behavior therapy (DBT) in an inpatient setting. We assumed that the change of the therapist between DBT-briefing and start of DBT-treatment as well as comorbid posttraumatic stress disorder (PTSD) and childhood trauma history were associated with elevated dropout. Eighty-nine participants with borderline pathology (≥ 3 borderline personality disorder criteria) receiving an inpatient DBT program completed a quality assurance questionnaire set assessing demographic information and pretreatment psychopathology during the days of their inpatient stay. Beyond that, changes of therapists were documented. The predictor analyses were investigated with generalized estimating equations. The dropout rate was 24.7%. A change of therapist between DBT-briefing and treatment as well as high childhood emotional abuse was associated with premature termination of treatment. Higher values of physical neglect during childhood were associated with a protective effect on treatment dropout. Surprisingly, this was also true for comorbid PTSD. This study supports the importance of therapy process variables as predictors of therapy dropout in borderline pathology. A change of therapist between DBT-briefing and treatment was associated with an increased vulnerability for dropping out of treatment and should therefore be avoided if possible. Against our hypotheses, a comorbid PTSD was even protective with regard to DBT dropout. Therefore, this severely suffering patient group should not be rejected from treatment assuming them to be too unstable for psychotherapy. However, results need to be replicated.

To study the efficacy and safety of acupuncture therapy for the improvement of sleep quality of outpatients receiving methadone maintenance treatment (MMT). Using randomized double-blinded controlled design, seventy-five MMT outpatients with low sleep quality [score of Pittsburgh sleep quality index (PSQI) > or = 8], were randomly assigned to the acupuncture group (38 cases) and the sham-acupuncture group (37 cases). All patients maintained previous MMT. Acupuncture was applied to Baihui (GV20), Shenmen (bilateral, TF4), Shenting (GV24), Sanyinjiao (bilateral, SP6), and Sishencong (EX-HN1) in the acupuncture group. The same procedures were performed in the sham-acupuncture group, but not to the acupoints (5 mm lateral to the acupoints selected in the acupuncture group) with shallow needling technique. The treatment was performed 5 times each week for 8 successive weeks. The PSQI was assessed before treatment, at the end of the 2nd, 4th, 6th, and 8th week of the treatment. The detection ratio of low sleep quality and the incidence of adverse acupuncture reactions were compared between the two groups at the end of the 8th week. The overall PSQI score was obviously higher in the acupuncture group than in the sham-acupuncture group with statistical difference (P < 0.01). The detection ratio of low sleep quality at the end of the 8th week was lower in the acupuncture group (60.53%, 23/38 cases) than in the sham-acupuncture group (83.78%, 31/37 cases) with statistical difference (P < 0.05). The rate of adverse acupuncture reaction was 5.26% (2/38 cases) in the acupuncture group and 2.70% (1/37 cases) in the sham-acupuncture group respectively, showing no statistical difference (P > 0.05). Acupuncture therapy could effectively and safely improve the sleep quality of outpatients receiving MMT.

The aims of the present study were to evaluate the health-related quality of life (HRQL) and treatment satisfaction (TS) of adults and children with primary antibody deficiencies (PAD) before and after the introduction of subcutaneous immunoglobulin G (SCIG) self-infusions at home and to identify prognostic factors (demographic/social, medical, patient/parent reported) for HRQL. 85 adults and 21 parents of children with PAD answered the SF-36 (adults), CHQ-PF50 (parents), and the LQI (adults and parents) at baseline and following 10 months of weekly self-administered SCIG infusions at home. The SCIG home therapy was associated with significant improvements in HRQL and TS, particularly in patients who had previously received IVIG therapy in hospital settings. Background factors that were found to be associated with HRQL changes in adults were age, serum IgG levels at month 10, concomitant joint/muscle/skeletal disorders, clinical study location and smoking status.

The aim of the study was to determine whether thyroid hormones level on admission in patients with ischemic stroke, treated with intravenous recombinant tissue type plasminogen activator (rtPA), was associated with symptomatic intracranial hemorrhage (sICH) and worse outcomes at 3 months.Patients with acute ischemic stroke (AIS) receiving intravenous rtPA thrombolytic treatment on our stroke unit between January 2015 and June 2016 were included in this study. Serum-free triiodothyronine (fT3), free thyroxine (fT4), total triiodothyronine (tT3), total thyroxine (tT4), and thyroid-stimulating hormone (TSH) were detected on admission. The endpoints were sICH, and poor functional outcomes at 3 and 6 months.In all, 159 patients (106 males; mean age 65.36 ± 10.02 years) were included. FT3 was independently associated with sICH (odds ratio [OR] 0.204, 95% confidence interval [CI] 0.065-0.642) and poor outcomes at 3 months (OR 0.396, 95% CI 0.180-1.764). The cut-off values of fT3 for sICH was 3.54 pg/mL (sensitivity 83%; specificity 83%; area under the curve 0.88). FT3 values ≤3.54 pg/mL increased risk for sICH by 3.16-fold (95% CI 0.75-1.0) compared with fT3 values >3.54 pg/mL.Low fT3 levels at admission were independently associated with sICH and worse outcomes at 3 months in AIS patients receiving rtPA thrombolytic therapy.

The objective of this study was to analyze medical costs and healthcare resource utilization (HRU) associated with everolimus-based therapy or chemotherapy among elderly women with hormone-receptor-positive, human-epidermal-growth-factor-receptor-2-negative (HR+/HER2-) metastatic breast cancer (mBC). Elderly women (≥65 years) with HR+/HER2- mBC who failed a non-steroidal-aromatase-inhibitor and subsequently began a new line of treatment with everolimus-based therapy or chemotherapy for mBC (index therapy) during July 20, 2012 to March 31, 2014 were identified from two large commercial claims databases. All-cause, BC-, and adverse event (AE)-related medical costs (2014 USD), and all-cause and AE-related HRU per patient per month (PPPM) were compared between patients treated with everolimus-based therapy and chemotherapy across their first four lines of therapy for mBC. Adjusted costs and HRU differences were estimated by pooling all lines and using multivariable models adjusted for differences in patient characteristics. In total, 925 elderly patients (mean age approximately 73 years) with HR+/HER2- mBC met the inclusion criteria; 230 received everolimus-based therapy (240 lines) and 737 received chemotherapy (939 lines). Compared with chemotherapy, everolimus-based therapy was associated with significantly lower total all-cause PPPM medical services costs (adjusted mean difference: $4007), driven by lower inpatient ($1994) and outpatient ($1402) costs; lower BC-related medical services costs ($3129), driven by both BC-related inpatient ($1883) and outpatient costs ($913); and lower AE-related medical services costs ($1873; all P < 0.01). Additionally, compared to patients treated with chemotherapy, patients treated with everolimus-based therapy had fewer all-cause outpatient visits (adjusted incidence rate ratio = 0.69), BC-related outpatient visits (0.66), other-medical-service visits (0.65), and AE-related HRU (0.59), which was driven by significantly

To test the ability of a reverse transcriptase-PCR (RT-PCR) assay, based on gene expression profiles, to accurately determine the risk of recurrence in patients with node-negative breast cancer who did not receive systemic therapy using formalin-fixed, paraffin-embedded tissue. A secondary objective was to determine whether the quantitative RT-PCR data correlated with immunohistochemistry assay data regarding estrogen receptor, progesterone receptor, and human epidermal growth factor receptor 2 status. We obtained archival paraffin-embedded tissue from patients with invasive breast cancer but no axillary lymph node involvement who had received no adjuvant systemic therapy and been followed for at least 5 years. RNA was extracted from three 10-microm-thick sections. The expression of 16 cancer-related genes and 5 reference genes was quantified using RT-PCR. A gene expression algorithm was used to calculate a recurrence score for each patient. We then assessed the ability of the test to accurately predict distant recurrence-free survival in this population. We identified 149 eligible patients. Median age at diagnosis was 59 years; mean tumor diameter was 2 cm; and 69% of tumors were estrogen receptor positive. Median follow-up was 18 years. The 5-year disease-free survival rate for the group was 80%. The 21 gene-based recurrence score was not predictive of distant disease recurrence. However, a high concordance between RT-PCR and immunohistochemical assays for estrogen receptor, progesterone receptor, and human epidermal growth factor receptor 2 status was noted. RT-PCR can be done on paraffin-embedded tissue to validate the large numbers of genes associated with breast cancer recurrence. However, further work needs to be done to develop an assay to identify the likelihood of recurrent disease in patients with node-negative breast cancer who do not receive adjuvant tamoxifen or chemotherapy.

Identification of Risk Factors for Nephrotoxicity in Patients Receiving Extended-Duration, High-Trough Vancomycin Therapy

Background: In the past, impurities in vancomycin formulations were thought to contribute to nephrotoxicity. In contrast, when current, purer formulations are dosed at conventional trough levels (i.e., 5–15 mg/L), the incidence of nephrotoxicity is relatively low. Recent guidelines have recommended targeting higher vancomycin trough levels in treatment of complicated methicillin-resistant Staphylococcus aureus infections. Dosing based on these higher trough levels may be associated with nephrotoxicity, so the potential risk factors for vancomycin-associated nephrotoxicity require clearer definition. Objectives: To determine the occurrence of nephrotoxicity in patients receiving more than 7 days of vancomycin therapy with high trough levels (15–20 mg/L) and to identify and evaluate specific risk factors related to development of vancomycin-associated nephrotoxicity (i.e., serum creatinine ≥ 44.2 μmol/L or increase ≥ 50% [i.e., ≥ 26.2 μmol/L] from baseline on 2 consecutive days). Methods: Health care records were reviewed for patients seen at 2 major teaching hospitals between January 2008 and March 2011. Patients who had attained high trough levels of vancomycin were screened for eligibility. Patients with unstable renal function, those undergoing hemodialysis, and those for whom dosage and/or sampling times were unclear were excluded. Univariate and multivariate analyses were performed to identify risk factors associated with nephrotoxicity. Univariate variables with p < 0.1 were included in the logistic regression model. Results: Of the 176 patients with high trough levels included in the analysis, 24 (14%) experienced nephrotoxicity. In univariate analysis, admission to a general medicine unit (the setting of care for 16 [67%] of the 24 patients with nephrotoxicity) and extended duration of vancomycin treatment were identified as risk factors for nephrotoxicity (p < 0.1). Other risk factors included gastrointestinal comorbidity (p = 0.056), malignancy

Response rates and immunologic memory following measles vaccination are reduced in human immunodeficiency virus (HIV)-infected children in the absence of highly active antiretroviral therapy (HAART). HIV-infected children 2 to <19 years old receiving HAART and with HIV loads <30,000 copies/mL, CD4% ≥15, and ≥1 prior measles-mumps-rubella vaccination (MMR) were given another MMR. Measles antibody concentrations before and 8, 32, and 80 weeks postvaccination were determined by plaque reduction neutralization (PRN). A subset was given another MMR 4-5 years later, and PRN antibody was measured before and 7 and 28 days later. At entry, 52% of 193 subjects were seroprotected (PRN ≥120 mIU/mL). Seroprotection increased to 89% 8 weeks postvaccination, and remained at 80% 80 weeks postvaccination. Of 65 subjects revaccinated 4-5 years later, 85% demonstrated memory based on seroprotection before or 7 days after vaccination. HIV load ≤400 copies/mL at initial study vaccination was associated with higher seroprotection rates, greater antibody concentrations, and memory. Grade 3 fever or fatigue occurred in 2% of subjects. Measles revaccination induced high rates of seroprotection and memory in children receiving HAART. Both endpoints were associated with HIV viral load suppression.

To investigate the rate of and risk factors for restless legs syndrome (RLS) augmentation in Japanese patients receiving pramipexole (PPX) treatment. Records of 231 consecutive patients with idiopathic RLS who received PPX therapy for more than one month in a single sleep disorder center were analyzed retrospectively. Augmentation was diagnosed based on the Max Planck Institute criteria; associated factors were identified by logistic regression analysis. Mean age at PPX initiation was 60.6 ± 14.9 years and mean treatment duration was 48.5 ± 26.4 months. Augmentation was diagnosed in 21 patients (9.1%). Daily PPX dose and treatment duration were significantly associated with augmentation. By analyzing the receiver operating characteristic curve, a PPX dose of 0.375 mg/day was found to be the optimal cut-off value for predicting augmentation. After stratifying patients according to PPX treatment duration, at median treatment duration of 46 months, optimal cut-off values for daily doses were 0.375 and 0.500 mg/day for <46 months and ≥46 months of treatment, respectively. The RLS augmentation with PPX treatment in Japanese patients was occurred at rate of 9.1%, being quite compatible with previously reported rates in Caucasian patients. The symptom could appear within a relatively short period after starting the treatment in possibly vulnerable cases even with a smaller drug dose. Our results support the importance of keeping doses of PPX low throughout the RLS treatment course to prevent augmentation. PMID:28264052

Background 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. Methods 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. Results 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. Conclusions 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.

A thrombolytic protease named kitamase possessing anticoagulant property was purified from edible and medicinal plant Aster yomena (Kitam.) Honda. Kitamase showed a molecular weight of 50 kDa by SDS-PAGE and displayed a strong fibrin zymogram lysis band corresponding to the similar molecular mass. The enzyme was active at high temperatures (50°C). The fibrinolytic activity of kitamase was strongly inhibited by EDTA, EGTA, TPCK and PMSF, inhibited by Zn(2+). The Km and Vmax values for substrate S-2251 were determined as 4.31 mM and 23.81 mM/mg respectively. It dissolved fibrin clot directly and specifically cleaved the α, Aα and γ-γ chains of fibrin and fibrinogen. In addition, kitamase delayed the coagulation time and increased activated partial thromboplastin time and prothrombin time. Kitamase exerted a significant protective effect against collagen and epinephrine induced pulmonary thromboembolism in mice. These results suggest that kitamase may have the property of metallo-protease like enzyme, novel fibrino(geno)lytic enzyme and a potential to be a therapeutic agent for thrombosis.

Purpose: With the advent of newer cancer therapies (eg, biologic and cytotoxic), treatment is becoming increasingly expensive for patients with cancer. Patients enrolled in Medicare and commercial insurance plans often have large copay requirements with each treatment cycle. Often, these patients undergo significant financial hardship, and some patients decline treatment. We have developed a support program that works closely with all copay assistance foundations to secure financial assistance to facilitate appropriate treatment. Methods: In September, 2008 we initiated a coordinated program with various copay assistance foundations, including Healthwell, Cancer Care, Patient Access, Chronic Disease Fund, Beckstrand Cancer, Lilly Cares and the Leukemia and Lymphoma Society. Patients requesting assistance with chemotherapy copay were enrolled in this program. Information about income level, chemotherapy regimens, and associated copay was given to these foundations, who then determined the amount of monetary assistance. Results: Since the initiation of this program, of 201 patients who began receiving chemotherapy, 25 (12.4%) requested assistance with this program for either intravenous or oral treatments. The current results of time delays for foundation decision, success rates and administrative costs to secure funding will be presented at the time of the poster presentation. Conclusion: Copay for chemotherapy drugs is a financial hardship for a significant number of patients. Coordinated resources must be provided and reimbursed to facilitate appropriate and sustainable cancer care. This program is a successful model for other centers to adopt. PMID:21731517

Gastroesophageal reflux disease is a potential risk factor for idiopathic pulmonary fibrosis (IPF) progression; however, the impact of antacid therapy (AAT) is under debate. To evaluate the effect of AAT on IPF progression in pirfenidone-treated patients. This post hoc analysis included patients with IPF who received pirfenidone in 3 trials (CAPACITY [PIPF-004/PIPF-006] and ASCEND [PIPF-016]). Pulmonary function, exercise tolerance, survival, hospitalizations, and adverse events (AEs) over 52 weeks were analyzed by baseline AAT use. Disease progression was defined as a decrease in forced vital capacity (FVC) of ≥10%, a decrease in 6-min walking distance of ≥50 m, or death over 1 year. Of 623 patients, 44% received AAT. No significant differences were found at 52 weeks (AAT versus non-AAT, respectively) in disease progression (24.9 vs. 30.6%; p = 0.12), all-cause mortality rate (2.9 vs. 4.0%; p = 0.47), IPF-related mortality rate (1.1 vs. 2.0%; p = 0.37), all-cause hospitalization rate (16.1 vs. 18.3%; p = 0.48), or mean change in percent FVC (-2.7 vs. -3.1%; p = 0.44). A relative, but not absolute, FVC decline of ≥10% favored AAT (15 vs. 22%; p = 0.03). Severe gastrointestinal AEs (3.7 vs. 0.9%; p = 0.015) and severe pulmonary infections (3.7 vs. 1.1%; p = 0.035) were more frequent with AAT. AAT and pirfenidone had outcomes comparable to those of pirfenidone alone in patients with IPF, underscoring the need for prospective trials to elucidate the role of AAT with or without antifibrotic drugs as a treatment for IPF. © 2017 The Author(s) Published by S.

The purpose of this study was to determine prospectively whether bowel wall apparent diffusion coefficient (ADC) measurements can be used to monitor treatment response to infliximab therapy in the setting of pediatric small-bowel Crohn disease. Twenty-eight pediatric subjects with newly diagnosed biopsy-proven Crohn disease of the distal or terminal ileum treated with infliximab were enrolled. Subjects underwent MR enterography at baseline, 1 month after therapy, and 6 months after therapy. Imaging features were documented, including bowel wall ADC and arterial or enteric phase contrast-enhanced signal intensity normalized to that of unenhanced imaging. A linear mixed model assessed the relationship between ADC and time; patient age and sex and azathioprine combination therapy were covariates. The diagnostic performance (with 95% CIs) of an increase in bowel wall ADC of 20% or more for identifying response to infliximab was calculated using a decrease in normalized contrast-enhanced bowel wall signal intensity of 20% or more as the reference standard. Bowel wall ADC increased over time (mean [± SD], 1180 ± 200 × 10 -6 mm 2 /s at baseline, 1420 ± 420 × 10 -6 mm 2 /s at 1 month, and 1450 ± 450 × 10 -6 mm 2 /s at 6 months; p = 0.0003); azathioprine therapy modulated this rate of change (p = 0.003). There was a statistically significant negative correlation between change in ADC and change in normalized contrast-enhanced signal intensity over time (ρ = -0.36; p < 0.001). The diagnostic performance of change in ADC for identifying response to infliximab therapy was sensitivity of 0.58 (95% CI, 0.34-0.80), specificity of 0.52 (95% CI, 0.31-0.72), positive predictive value of 0.48 (95% CI, 0.27-0.69), and negative predictive value of 0.62 (95% CI, 0.38-0.82). Bowel wall ADC increases over time in pediatric subjects receiving infliximab, but the diagnostic performance of ADC is likely insufficient for reliable treatment monitoring.

Background and Purpose Sex-specific disparities in stroke care including thrombolytic therapy and early hospital admission is reported. In a large registry of Florida and Puerto Rico hospitals participating in the Get With The Guidelines – Stroke (GWTG-S) program, we sought to determine sex-specific differences in ischemic stroke performance metrics and overall thrombolytic treatment. Methods 51,317 (49% women) patients were included from 73 sites from 2010–2014. Multivariable logistic regression with generalized estimating equations evaluated sex-specific differences in the pre-specified GWTG-S metrics for defect free care (DFC) in ischemic stroke, adjusting for age, race-ethnicity, insurance status, hospital characteristics, individual risk factors and the presenting stroke severity. Results As compared to men, women were older (73±15 vs. 69±14 years; p<0.0001), more hypertensive (67% vs. 63%, P<0.0001) and had more atrial fibrillation (19% vs. 16%; p<0.0001). DFC was slightly lower in women than men (OR 0.96, 95% CI 0.93–1.00). Temporal trends in DFC improved substantially and similarly for men and women, with a 29% absolute improvement in women (p for trend <0.0001) and 28% in men (p for trend <0.0001), p value for time-by-sex interaction of 0.13. Women were less likely to receive thrombolysis (OR 0.92, 95%CI 0.86–0.99, P=0.02) and less likely to have a door to needle time (DTN) <1 hour (OR 0.83, 95%CI, 0.71–0.97, p=0.02) as compared to men Conclusion Women received comparable stroke care to men in this registry as measured by pre-specified GWTG metrics. However, women less likely received thrombolysis and had DTN <1 hour, an observation that calls for implementation of interventions to reduce sex-disparity in these measures. PMID:27553032

Thirty-two adults hospitalized with skin and skin structure infections received intravenous ofloxacin followed by oral ofloxacin. The standard treatment was 400 mg every 12 h. One patient with renal failure received 400 mg every 24 h. Serum ofloxacin levels were measured (1.5 h postdose and 1 h predose) during intravenous (32 patients) and oral (30 patients) therapy. Levels were assayed by high-pressure liquid chromatography (HPLC) and microbiological assay (MBA). Mean levels +/- standard deviation (in micrograms per milliliter) when measured by MBA after intravenous dosing were (postdose versus predose) 6.23 +/- 2.49 versus 2.42 +/- 1.56, and those after oral dosing were 6.17 +/- 3.25 versus 3.49 +/- 2.77. When measured by HPLC, mean levels +/- standard deviation after intravenous dosing were 5.81 +/- 2.08 versus 2.14 +/- 1.26 and those after oral dosing were 5.63 +/- 2.92 versus 3.41 +/- 2.98. There were no significant differences between levels achieved with oral or intravenous dosing when measured by either MBA or HPLC. Levels in serum did not correlate with side effects. The MICs for 50 and 90% of the 40 aerobic pathogens isolated from 21 patients were 0.5 and 2.0 micrograms/ml, respectively. Cure or improvement was achieved in 30 patients. Intravenous and oral administration of ofloxacin yielded similar levels in serum which were safe and effective in the therapy of skin infections in adult patients. PMID:1810189

Endoscopy is the gold standard for the diagnosis and follow-up of patients with Crohn disease (CD). However, a less invasive approach is now being sought for the management of these patients. The objective of this study was to examine whether (18)F-fluorodeoxyglucose (FDG)-positron emission tomography (PET) might be relevant for monitoring the disease activity in CD patients undergoing granulocyte/monocyte apheresis (GMA). This study was conducted in 12 patients with CD who were receiving treatment with 10 once-a-week GMA sessions with the Adacolumn. The response to treatment was monitored by measuring standard laboratory variables, Crohn's Disease Activity Index (CDAI) score, International Organization for the Study of Inflammatory Bowel Diseases (IOIBD) score, and regional and global bowel uptakes on FDG-PET. In 6 of the 12 patients, significant improvement of the CDAI was observed after the final session of GMA. The patients who showed clinical response to GMA had a decrease in the regional and global bowel uptakes on FDG-PET, whereas those who did not respond showed no change. In the patients who responded to the GMA, the decrease in regional bowel uptake on FDG-PET in each disease area of the same patient varied in parallel. There was a significant correlation between decrease in the global bowel uptake on FDG-PET and improvement of the CDAI and IOIBD scores. The longitudinal changes in FDG-PET uptakes are of potential clinical interest for assessing the regional and global bowel disease activity in CD patients undergoing GMA therapy.

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.

To determine the incidence and severity of bleeding events requiring hospitalization among patients with atrial fibrillation (AF) receiving anticoagulants (dabigatran or warfarin) or antiplatelet agents (eg, aspirin and clopidogrel). This was a single-center, retrospective cohort study involving 1494 patients with AF hospitalized from November 1, 2010, to November 1, 2011, with prior warfarin, dabigatran, or antiplatelet therapy. Overall bleeding events in the dabigatran group compared to the warfarin group were 24% and 12%, respectively ( P = .004). Of these events, individually, there were no significant differences in major (56% vs 58%, P = .88), life-threatening (25% vs 36%, P = .38), or minor bleeding (44% vs 42%, P = .06). Gastrointestinal (GI) bleeding occurred more in the dabigatran group compared to the warfarin group ( P = .02). Intracranial bleeding occurred in 15% of patients in the warfarin group and did not occur at all in the dabigatran group. Warfarin patients had significantly more overall bleeding events compared to antiplatelet therapy ( P < .001), with an increasing trend seen in major bleeding ( P = .06). GI bleeding, however, favored the warfarin group over the antiplatelet group (48% vs 73%, P = .04). Anticoagulation with dabigatran was associated with an overall increased occurrence of bleeding requiring hospital admission compared to warfarin. GI bleeding was more prevalent with dabigatran and antiplatelets than with warfarin. There were more intracranial hemorrhages seen in the warfarin group.

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.

Summary Background Constraint-Induced Movement therapy (CIMT) uses a variety of treatment components, including restricted use of the better upper extremity, to promote increased use of the contralesional limb for many hours each weekday over two consecutive weeks. The EXCITE Trial demonstrated the efficacy of this intervention for patients 3-9 months post-stroke who were followed for the next 12 months. We assessed the retention of improvements through 24 months. Method Measurements were made every four months for impaired upper extremity function (Wolf Motor Function Test - WMFT and Motor Activity Log - MAL) and health related quality of life (Stroke Impact Scale - SIS) amongst 106/222 participants randomized into one arm of the EXCITE Trial in which they received CIMT rather than usual and customary care. Findings There was no observed regression from the treatment effects observed at 12 months after treatment during the next 12 months for the primary outcome measures of WMFT and MAL. In fact, the additional changes were in the direction of increased therapeutic effect. For the strength components of the WMFT the changes were significant (P < .05) Secondary outcome variables, including the SIS, exhibited a similar pattern. Interpretation Mild to moderately impaired patients who are 3-9 months post-stroke demonstrate substantial improvement in functional use of the paretic upper extremity and quality of life 2 years after receiving a 2-week CIMT intervention. Thus this intervention has persistent benefits. PMID:18077218

There is insufficient research on whether direct-acting antiviral (DAA) therapy can improve liver fibrosis in patients with chronic hepatitis C virus (HCV). We evaluated sequential changes in liver stiffness using shear wave elastography in patients with HCV who received DAA therapy. A total of 210 patients with HCV who received daclatasvir and asunaprevir therapy and achieved sustained virological response (SVR) were analyzed. Liver stiffness, as evaluated by shear wave elastography, and laboratory data were assessed before treatment (baseline), at end of treatment (EOT), and at 24 weeks after EOT (SVR24). Alanine aminotransferase levels (ALT) decreased over time, and there were significant differences between baseline and EOT and between EOT and SVR24. Although platelet counts did not significantly differ between baseline and EOT, they increased significantly from EOT to SVR24. The median (interquartile range) liver stiffness values at baseline, EOT, and SVR24 were 10.2 (7.7-14.7), 8.8 (7.1-12.1), and 7.6 (6.3-10.3) kPa, respectively (P < 0.001, baseline vs EOT; P < 0.001, EOT vs SVR24). Additionally, in patients with ALT ≤ 30 (indicating low necroinflammatory activity in the liver) and Fibrosis-4 index > 2.0 (n = 75), the liver stiffness values at baseline, EOT, and SVR24 were 9.6 (7.7-15.2), 9.2 (7.3-12.1), and 7.7 (6.3-10.1) kPa, respectively (P < 0.001, baseline vs EOT; P < 0.001, EOT vs SVR24). These results suggest that early improvement of liver stiffness starts during the administration of DAAs in patients who achieve SVR, and this effect is particularly pronounced in patients with progressive liver fibrosis. © 2017 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.

We summarize the clinical history and laboratory results following the introduction of tenofovir among 6 patients coinfected with human immunodeficiency virus (HIV) and hepatitis B virus (HBV) who presented with severe liver disease while receiving lamivudine-based highly active antiretroviral therapy. In all cases, the introduction of tenofovir led to a sustained undetectable HBV and HIV loads, with marked clinical and laboratory improvement in liver function. We provide supporting evidence for the role of tenofovir in the management of advanced HBV infection in HIV-positive patients after the development of lamivudine resistance.

To explore the efficacy of mindfulness-
based music therapy (MBMT) to improve attention and decrease mood distress experienced by women with breast cancer receiving adjuvant chemotherapy. Quantitative, descriptive, longitudinal approach. A comprehensive cancer hospital and a university in southern Florida. 15 women with a diagnosis of breast cancer, stages I-III, receiving adjuvant chemotherapy. Participants individually received MBMT for one hour per week for four weeks. The sessions consisted of varied music activities accompanied by mindfulness attitudes, or mental strategies that enhance moment-to-moment awareness, and weekly homework. Demographic information was collected at baseline. Attention was measured using Conners' Continuous Performance Test II. Mood was measured using the Profile of Mood States-Brief Form. Narrative comments collected from the homework assignments served to reinforce quantitative data. Repeated measures analysis of variance showed that attention improved significantly over time. Although all mood states significantly improved from the beginning to the end of each MBMT session, the mood state of fatigue decreased significantly more than the other mood states. MBMT enhances attention and mood, particularly the mood state of fatigue, in women with breast cancer receiving adjuvant chemotherapy. 
. A preferred music listening and mindfulness exercise may be offered to women with breast cancer who experience attention problems and mood distress.

To evaluate the characteristics and overall survival rates of early stage cervical cancer (FIGO IB-IIA) patients who receive definitive radiation therapy and those who are prescribed adjuvant postoperative radiation and to conduct a factors analysis of the variables that affect the overall survival rates in both groups of therapy. The medical records of 85 patients with cervical cancer FIGO stages IB-IIA who were treated at the Department of Radiotherapy of Cipto Mangunkusumo Hospital were reviewed and analyzed to determine their overall survival and the factors that affected it between a definitive radiation group and an adjuvant postoperative radiation group. There were 25 patients in the definitive radiation and 60 patients in the adjuvant radiation group. The overall survival rates in the adjuvant radiation group at years one, two, and three were 96.7%, 95%, and 93.3%, respectively. Negative lymph node metastasis had an average association with overall survival (p < 0.2). In the definitive radiation group, overall survival at years one, two, and three were 96%, 92%, and 92%, respectively. A hemoglobin (Hb) level >12 g/dl was a factor with an average association with the overall survival (p < 0.2). The differences between both groups of therapy were not statistically significant (92% vs. 93.3%; p = 0.138). This study did not show any statistically significant overall survival for cervical cancer FIGO stage IB-IIA patients who received definitive radiation or adjuvant postoperative radiation. Negative lymph node metastasis had an effect on the overall survival rate in the adjuvant postoperative radiation group, while a preradiation Hb level >12 g/dl tended to affect the overall survival in the definitive radiation group patients.

Edaravone, a potent antioxidant, may improve thrombolytic therapy because it benefits ischemic stroke patients on its own and mitigates adverse effects of tissue plasminogen activator (tPA) in preclinical models. However, whether the combined tPA-edaravone therapy is more effective in reducing infarct size than singular treatment is uncertain. Here we investigated this issue using a transient hypoxia-ischemia (tHI)-induced thrombotic stroke model, in which adult C57BL/6 mice were subjected to reversible ligation of the unilateral common carotid artery plus inhalation of 7.5% oxygen for 30 min. While unilateral occlusion of the common carotid artery suppressed cerebral blood flow transiently, the addition of hypoxia triggered reperfusion deficits, endogenous thrombosis, and attenuated tPA activity, leading up to infarction. We compared the outcomes of vehicle-controls, edaravone treatment, tPA treatment at 0.5, 1, or 4 h post-tHI, and combined tPA-edaravone therapies with mortality rate and infarct size as the primary end-points. The best treatment was further compared with vehicle-controls in behavioral, biochemical, and diffusion tensor imaging (DTI) analyses. We found that application of tPA at 0.5 or 1 h--but not at 4 h post-tHI--significantly decreased infarct size and showed synergistic (p<0.05) or additive benefits with the adjuvant edaravone treatment, respectively. The acute tPA-edaravone treatment conferred >50% reduction of mortality, ∼ 80% decline in infarct size, and strong white-matter protection. It also improved vascular reperfusion and decreased oxidative stress, inflammatory cytokines, and matrix metalloproteinase activities. In conclusion, edaravone synergizes with acute tPA treatment in experimental thrombotic stroke, suggesting that clinical application of the combined tPA-edaravone therapy merits investigation.

We assessed differences in locoregional outcome based on receptor status combinations in a cohort of stage II-III breast cancer patients treated with modern trimodality therapy. Medical records of 582 consecutively treated patients receiving post-mastectomy radiation (PMRT) between 1/1999 and 12/2009 were reviewed. Rate of local regional recurrence (LRR) was estimated by the method of cumulative incidence allowing for competing risks. The effect of prognostic factors was examined by Gray's test and by Fine and Gray's modeling approach. Median follow-up was 44.7 months. Five-year progression-free survival (PFS) was 73.9% and overall survival (OS) was 84%. The cumulative 5-year incidence of LRR as first site of failure was 6.2% (95% CI 4.2-8.7). Five-year cumulative incidence of LRR was 8.6 versus 4.4% for estrogen receptor (ER) negative versus ER positive (P = 0.017), 8.5 versus 3.4% for progesterone receptor (PR) negative versus PR positive (P = 0.011), and 1.7 versus 7.5% for HER2 positive (86% received trastuzamab) versus HER2 negative (P = 0.032). Five-year cumulative incidence of LRR was 11.8% for the triple negative subtype and 3.9% for other receptor combinations (P < 0.001). Among patients whose disease is ER positive, 5-year LRR rate was 7.8 versus 3.4% for PR negative versus PR positive (P = 0.130). The prognostic value of the triple negative and HER2 negative subtypes was maintained on multivariate analysis. In the era of HER-2 targeted therapy, tumors that are HER-2 over expressing and are treated with trastuzumab have a very low rate of LRR. ER negative, PR negative, and triple negative status are associated with increased risk of LRR.

The aim of this study is to explore the associations between hormone treatment variables and depression, and the nature of depression in prostate cancer (PCa) patients by comparing the severity and symptom profile of anxiety and depression in men who were currently receiving hormone therapy (HT) versus those who were not. Self-reports of anxiety and depression on standardized scales of GAD and major depressive disorder (MDD) were collected from 156 PCa patients across two recruitment sites in Australia. Patients who were currently receiving HT were compared with patients not receiving HT for their severity and symptom profiles on GAD and MDD. Participants receiving HT had significantly higher GAD and MDD total scores than patients who were not receiving HT. In addition, the symptom profiles of these two HT subgroups were differentiated by significantly higher scores on the key criteria for GAD and MDD plus fatigue and sleeping difficulties but not the remaining symptoms of GAD and MDD. However, there were no significant differences between HT subgroups for the degree of functional impairment experienced by these symptoms. Although these data confirm the association between HT and anxiety/depression, the range of GAD and MDD symptoms influenced is relatively restricted. Moreover, functional ability does not appear to be impaired by HT. These findings clarify the ways in which HT affects PCa patients and suggests that a simple total scale score for anxiety and depression may not be as helpful in designing treatment as consideration of the symptomatic profiles of PCa patients receiving HT.

The aim of this study was to evaluate the efficacy and safety of mipomersen in hypercholesterolemic subjects taking stable statin therapy. Mipomersen is an apolipoprotein (apo) B synthesis inhibitor that has demonstrated significant reductions in apo B and low-density lipoprotein (LDL) cholesterol in Phase 1 clinical trials in healthy volunteers. A randomized, placebo-controlled, dose-escalation Phase 2 study was designed to evaluate the effects of mipomersen in hypercholesterolemic subjects taking stable statin therapy. Seventy-four subjects were enrolled sequentially into 1 of 6 dose cohorts at a 4:1 (active/placebo) ratio. Subjects received 7 doses of 30 to 400 mg over 5 weeks in the first 5 cohorts and 15 doses of 200 mg over 13 weeks in the sixth cohort. Pre-specified end points included percentage change from baseline in apo B and LDL cholesterol. Safety was assessed with laboratory test results and by the incidence and severity of adverse events. The apo B and LDL cholesterol were reduced by 19% to 54% and 21% to 52%, respectively, at doses of 100 mg/week mipomersen and higher in the 5-week treatment cohorts. Efficacy seemed to increase upon treatment for 13 weeks at a dose of 200 mg/week. Injection site reactions (mild to moderate erythema [90%]) and hepatic transaminase increases (17%) were the most common adverse events, leading to discontinuation in 2 subjects and 1 subject, respectively. In the 13-week treatment cohort, 5 of 10 subjects (50%) had elevations >or=3x the upper limit of normal, 4 of which persisted on 2 consecutive occasions. Mipomersen might hold promise for treatment of patients not reaching target LDL cholesterol levels on stable statin therapy. Further studies are needed to address the mechanisms and clinical relevance of transaminase changes after mipomersen administration.

To examine the mediators and the potential of treatment matching to improve outcome for cognitive behavior therapy (CBT) for insomnia. Participants were 188 adults (117 women; Mage = 47.4 years, SD = 12.6) meeting the Diagnostic and Statistical Manual of Mental Disorders (4th ed.; text rev.; DSM-IV-TR; American Psychiatric Association [APA], 2000) diagnostic criteria for chronic insomnia (Mduration: 14.5 years, SD: 12.8). Participants were randomized to behavior therapy (BT; n = 63), cognitive therapy (CT; n = 65), or CBT (n = 60). The outcome measure was the Insomnia Severity Index (ISI). Hypothesized BT mediators were sleep-incompatible behaviors, bedtime variability (BTv), risetime variability (RTv) and time in bed (TIB). Hypothesized CT mediators were worry, unhelpful beliefs, and monitoring for sleep-related threat. The behavioral processes mediated outcome for BT but not CT. The cognitive processes mediated outcome in both BT and CT. The subgroup scoring high on both behavioral and cognitive processes had a marginally significant better outcome if they received CBT relative to BT or CT. The subgroup scoring relatively high on behavioral but low on cognitive processes and received BT or CBT did not differ from those who received CT. The subgroup scoring relatively high on cognitive but low on behavioral processes and received CT or CBT did not differ from those who received BT. The behavioral mediators were specific to BT relative to CT. The cognitive mediators were significant for both BT and CT outcomes. Patients exhibiting high levels of both behavioral and cognitive processes achieve better outcome if they receive CBT relative to BT or CT alone.

A suicide bomb blast in 2013 at a distant city of Pakistan killed 84 and wounded more than 150 people. Some patients were transferred to our tertiary care hospital because of extreme load on medical services there. This patient arrived at the Aga Khan Hospital, 2 days after the bomb blast injury and underwent an orthopedic procedure. Next day, he developed sudden tachypnea, desaturation, and circulatory collapse. After initial cardiopulmonary resuscitation, he was immediately transferred to surgical intensive care unit. Based on history, echocardiography findings and patient parameters, a clinical diagnosis of massive pulmonary embolism was made and immediate thrombolytic therapy with alteplase was started. The immediate improvement in hemodynamic status was evident following 2 hours of alteplase infusion. This case also highlights the aggressiveness of resuscitation, decision making in initiating thrombolytic therapy on clinical grounds, importance of deep venous thrombosis prophylaxis, and exhaustion of health resources due to blast related mass destruction.

Background. Response rates and immunologic memory following measles vaccination are reduced in human immunodeficiency virus (HIV)–infected children in the absence of highly active antiretroviral therapy (HAART). Methods. HIV-infected children 2 to <19 years old receiving HAART and with HIV loads <30 000 copies/mL, CD4% ≥15, and ≥1 prior measles-mumps-rubella vaccination (MMR) were given another MMR. Measles antibody concentrations before and 8, 32, and 80 weeks postvaccination were determined by plaque reduction neutralization (PRN). A subset was given another MMR 4–5 years later, and PRN antibody was measured before and 7 and 28 days later. Results. At entry, 52% of 193 subjects were seroprotected (PRN ≥120 mIU/mL). Seroprotection increased to 89% 8 weeks postvaccination, and remained at 80% 80 weeks postvaccination. Of 65 subjects revaccinated 4–5 years later, 85% demonstrated memory based on seroprotection before or 7 days after vaccination. HIV load ≤400 copies/mL at initial study vaccination was associated with higher seroprotection rates, greater antibody concentrations, and memory. Grade 3 fever or fatigue occurred in 2% of subjects. Conclusions. Measles revaccination induced high rates of seroprotection and memory in children receiving HAART. Both endpoints were associated with HIV viral load suppression.

We explored the variation in country mortality rates in the paediatric population receiving renal replacement therapy across Europe, and estimated how much of this variation could be explained by patient-level and country-level factors. In this registry analysis, we extracted patient data from the European Society for Paediatric Nephrology/European Renal Association-European Dialysis and Transplant Association (ESPN/ERA-EDTA) Registry for 32 European countries. We included incident patients younger than 19 years receiving renal replacement therapy. Adjusted hazard ratios (aHR) and the explained variation were modelled for patient-level and country-level factors with multilevel Cox regression. The primary outcome studied was all-cause mortality while on renal replacement therapy. Between Jan 1, 2000, and Dec 31, 2013, the overall 5 year renal replacement therapy mortality rate was 15·8 deaths per 1000 patient-years (IQR 6·4-16·4). France had a mortality rate (9·2) of more than 3 SDs better, and Russia (35·2), Poland (39·9), Romania (47·4), and Bulgaria (68·6) had mortality rates more than 3 SDs worse than the European average. Public health expenditure was inversely associated with mortality risk (per SD increase, aHR 0·69, 95% CI 0·52-0·91) and explained 67% of the variation in renal replacement therapy mortality rates between countries. Child mortality rates showed a significant association with renal replacement therapy mortality, albeit mediated by macroeconomics (eg, neonatal mortality reduced from 1·31 [95% CI 1·13-1·53], p=0·0005, to 1·21 [0·97-1·51], p=0·10). After accounting for country distributions of patient age, the variation in renal replacement therapy mortality rates between countries increased by 21%. Substantial international variation exists in paediatric renal replacement therapy mortality rates across Europe, most of which was explained by disparities in public health expenditure, which seems to limit the availability and

People living in rural Australia are more likely to die in hospital following an acute myocardial infarction than those living in major cities. While several factors, including time taken to access hospital care, contribute to this risk, it is also partially attributable to the lower uptake of evidence-based guidelines for the administration of thrombolytic drugs in rural emergency departments where up to one-third of eligible patients do not receive this life-saving intervention. Clinical pathways have the potential to link evidence to practice by integrating guidelines into local systems, but their impact has been hampered by variable implementation strategies and sub-optimal research designs. The purpose of this study is to determine the impact of a five-step clinical pathways implementation process on the timely and efficient administration of thrombolytic drugs for acute myocardial infarctions managed in rural Australian emergency departments. The design is a two-arm, cluster-randomised trial with rural hospital emergency departments that treat and do not routinely transfer acute myocardial infarction patients. Six rural hospitals in the state of Victoria will participate, with three in the intervention group and three in the control group. Intervention hospitals will participate in a five-step clinical pathway implementation process: engagement of clinicians, pathway development according to local resources and systems, reminders, education, and audit and feedback. Hospitals in the control group will each receive a hard copy of Australian national guidelines for chest pain and acute myocardial infarction management. Each group will include 90 cases to give a power of 80% at 5% significance level for the two primary outcome measures: proportion of those eligible for thrombolysis receiving the drug and time to delivery of thrombolytic drug. Improved compliance with thrombolytic guidelines via clinical pathways will increase acute myocardial infarction survival

Vaginal infections are a risk factor for preterm delivery. In this study, we sought to evaluate the vaginal flora of pregnant women receiving opioid maintenance therapy (OMT) in comparison to non-dependent, non-maintained controls. A total of 3763 women with singleton pregnancies who underwent routine screening for asymptomatic vaginal infections between 10 + 0 and 16 + 0 gestational weeks were examined. Vaginal smears were Gram-stained, and microscopically evaluated for bacterial vaginosis, candidiasis, and trichomoniasis. In a retrospective manner, data of 132 women receiving OMT (cases) were matched for age, ethnicity, parity, education, previous preterm delivery, and smoking status to the data of 3631 controls. The vaginal flora at antenatal screening served as the primary outcome measure. Secondary outcome measures were gestational age and birth weight. In the OMT group, 62/132 (47 %) pregnant women received methadone, 39/132 (29.5 %) buprenorphine, and 31/132 (23.5 %) slow-release oral morphine. Normal or intermediate flora was found in 72/132 OMT women (54.5 %) and 2865/3631 controls [78.9 %; OR 0.49 (95 % CI, 0.33-0.71); p < 0.001]. Candidiasis occurred more frequently in OMT women than in controls [OR 2.11 (95 % CI, 1.26-3.27); p < 0.001]. Findings were inconclusive regarding bacterial vaginosis (± candidiasis) and trichomoniasis. Compared to infants of the control group, those of women with OMT had a lower mean birth weight [MD -165.3 g (95 % CI, -283.6 to -46.9); p = 0.006]. Pregnant women with OMT are at risk for asymptomatic vaginal infections. As recurrent candidiasis is associated with preterm delivery, the vulnerability of this patient population should lead to consequent antenatal infection screening at early gestation.

The purpose of this study was to investigate the incidence of fosaprepitant-associated infusion site adverse events (ISAEs) among a cohort of breast cancer patients receiving doxorubicin/cyclophosphamide (AC) chemotherapy. A retrospective review of electronic medical record (EMR) data was performed for all patients who were initiated on AC from January 2011 to April 2012. Data collected included baseline demographics, antiemetic regimen, documentation of ISAEs, and type of intravenous (IV) access. Descriptive statistics (mean and standard deviation or percentages) were summarized overall, by type of IV access and initial antiemetic given. Among the 148 patients included in this analysis, 98 initially received fosaprepitant and 44 received aprepitant. The incidence of ISAEs associated with fosaprepitant administration was 34.7 % (n=34), while the incidence of aprepitant-associated ISAEs was 2.3 % (n=1). All ISAEs were associated with peripheral IV access. The most commonly reported ISAEs were infusion site pain (n=26), erythema (n=22), swelling (n=12), superficial thrombosis (n=8), infusion site hives (n=5), and phlebitis/thrombophlebitis (n=5). Twenty-six patients experienced more than one type of ISAE. The incidence and severity of ISAEs associated with fosaprepitant administration among a group of patients receiving AC chemotherapy are significant and appreciably higher than what has been previously reported.

Multicenter, dose-ranging study of efegatran sulfate versus heparin with thrombolysis for acute myocardial infarction: The Promotion of Reperfusion in Myocardial Infarction Evolution (PRIME) trial.

PubMed

2002-01-01

Adjunctive therapies that increase the incidence of normal reperfusion after thrombolysis for acute myocardial infarction (MI) could enhance clinical outcomes. Direct thrombin inhibitors may offer an advantage over standard adjunctive therapies. We randomized 336 patients with acute MI at 33 sites to receive 1 of 5 doses of efegatran sulfate, a direct thrombin inhibitor, or heparin for 72 to 96 hours, both with accelerated alteplase and aspirin. The primary end point was the incidence of thrombolytic failure (death, reinfarction, or TIMI grade 0-2 flow in the infarct artery from 90 minutes to discharge or 30 days, whichever occurred earlier). Significantly more patients randomized to efegatran had evidence of heart failure at admission. The lowest-dose efegatran arm was terminated at 15 patients because of unacceptably increased thrombolytic failure. The primary end point occurred in 53.0% of patients treated with heparin, in 53.8% of patients treated with efegatran overall (P =.90), and in 55.4% of patients given intermediate-dose efegatran (P =.74). These findings were unaffected after adjustment was done for baseline differences. Most bleeding was minor; major bleeding and the use of blood transfusions did not differ significantly by treatment. Three patients in the high-dose efegatran group had intracranial hemorrhage, as did 1 patient in the heparin group. Continuous ST monitoring showed a shorter time to recovery for the efegatran group (median 107 minutes) compared with the heparin group (154 minutes; P =.025). Efegatran sulfate appeared to offer no clear advantage over heparin as an adjunct to thrombolysis for acute myocardial infarction, although there may be a modest improvement in time to reperfusion.

Therapeutic interventions can be classified into two distinct approaches: abstinent and maintenance method. Currently, there are no clear criteria for referring addicted patients to one of these modalities. We aimed to compare the personality characteristics of individuals with addiction who attended narcotics anonymous sessions with those who received methadone maintenance therapy. This was a cross- sectional study. The participants were NA members and patients who were undergoing methadone maintenance treatment in outpatient clinics. Using the randomized cluster sampling method, 200 individuals with opioid dependence were selected (each group 100 persons). Data were collected through a demographic questionnaire and the five-factor personality inventory (NEO-FFI). Comparison of the mean scores of NEO-PPI in the two groups was performed by independent t test, and qualitative variables were compared using the Chi-square test. We found a significant difference between the MMT and NA groups with respect to neuroticism, extroversion, and agreeableness. No significant difference was found in the subscales of conscientious and openness. People who regularly attended the NA sessions had lower neuroticism and higher agreeableness than patients who were under the maintenance modality. Whether this is the cause or effect of attending NA sessions requires future large-scale cohort studies.

The rejection of an application for ambulant geriatric rehabilitation (AGRV) is usually justified by the argument that non-pharmaceutical therapy prescribed by doctors accredited by social housing institutions (SHI) would suffice. The reality in healthcare during the 6 months following an application is unknown. In this study 203 patients who had made an application for AGRV in the second half of 2010 in Flensburg, Lübeck or Ratzeburg were interviewed by telephone. The survey revealed that 25.7% of the applications for AGRV had been rejected. The majority of these patients received no ambulant non-pharmaceutical therapy (e.g. physical therapy, physiotherapy, occupational therapy, speech therapy or psychological therapy), less than 20% received more than 12 therapy sessions and in most cases exclusively physiotherapy. The 141 successful AGRV applicants received additional ambulant therapies of a similar magnitude. The difference between the intensified interdisciplinary therapy offered in the AGRV and additionally and the offer to rejected applicants is substantial.

Stroke is a devastating disease and a leading cause of death and disability. Currently, the only FDA approved therapy for acute ischemic stroke is the intravenous administration of the thrombolytic medication, recombinant tissue plasminogen activator (tPA). However, this treatment has many contraindications and can have dangerous side effects such as intra-cerebral hemorrhage. These treatment limitations have led to much interest in potential adjunctive therapies, such as therapeutic hypothermia (T therapies with tPA to treat stroke, however little is known about the effects of temperature on the thrombolytic efficacy of tPA. In this work, we measure the temperature dependence of the fractional clot mass loss Deltam(T) resulting from tPA exposure in an in vitro human clot model. We find that the temperature dependence is well described by an Arrhenius temperature dependence with an effective activation energy E(eff) of 42.0 +/- 0.9 kJ mole(-1). E(eff) approximates the activation energy of the plasminogen-to-plasmin reaction of 48.9 kJ mole(-1). A model to explain this temperature dependence is proposed. These results will be useful in predicting the effects of temperature in future lytic therapies.

Stroke is a devastating disease and a leading cause of death and disability. Currently, the only FDA approved therapy for acute ischemic stroke is the intravenous administration of the thrombolytic medication, recombinant tissue plasminogen activator (tPA). However, this treatment has many contraindications and can have dangerous side effects such as intra-cerebral hemorrhage. These treatment limitations have led to much interest in potential adjunctive therapies, such as therapeutic hypothermia (T <= 35 °C) and ultrasound enhanced thrombolysis. Such interest may lead to combining these therapies with tPA to treat stroke, however little is known about the effects of temperature on the thrombolytic efficacy of tPA. In this work, we measure the temperature dependence of the fractional clot mass loss Δm(T) resulting from tPA exposure in an in vitro human clot model. We find that the temperature dependence is well described by an Arrhenius temperature dependence with an effective activation energy Eeff of 42.0 ± 0.9 kJ mole-1. Eeff approximates the activation energy of the plasminogen-to-plasmin reaction of 48.9 kJ mole-1. A model to explain this temperature dependence is proposed.

Abstract The aim of the study was to determine whether thyroid hormones level on admission in patients with ischemic stroke, treated with intravenous recombinant tissue type plasminogen activator (rtPA), was associated with symptomatic intracranial hemorrhage (sICH) and worse outcomes at 3 months. Patients with acute ischemic stroke (AIS) receiving intravenous rtPA thrombolytic treatment on our stroke unit between January 2015 and June 2016 were included in this study. Serum-free triiodothyronine (fT3), free thyroxine (fT4), total triiodothyronine (tT3), total thyroxine (tT4), and thyroid-stimulating hormone (TSH) were detected on admission. The endpoints were sICH, and poor functional outcomes at 3 and 6 months. In all, 159 patients (106 males; mean age 65.36 ± 10.02 years) were included. FT3 was independently associated with sICH (odds ratio [OR] 0.204, 95% confidence interval [CI] 0.065–0.642) and poor outcomes at 3 months (OR 0.396, 95% CI 0.180–1.764). The cut-off values of fT3 for sICH was 3.54 pg/mL (sensitivity 83%; specificity 83%; area under the curve 0.88). FT3 values ≤3.54 pg/mL increased risk for sICH by 3.16-fold (95% CI 0.75–1.0) compared with fT3 values >3.54 pg/mL. Low fT3 levels at admission were independently associated with sICH and worse outcomes at 3 months in AIS patients receiving rtPA thrombolytic therapy. PMID:29137061

This study sought to measure early strut coverage in patients receiving drug-eluting stents (DESs) and to explore the feasibility of short-term dual antiplatelet therapy (DAPT) based on the degree of early strut coverage. Data for early strut coverage in patients receiving new-generation DESs, and its implications for DAPT continuation were limited. A randomized, multicenter trial was conducted in 894 patients treated with DESs. Patients were randomly assigned to everolimus-eluting stent (EES) (n = 444) or biolimus-eluting stent (BES) (n = 450) groups and optical coherence tomography (OCT)-guided (n = 445) or angiography-guided (n = 449) implantation groups using a 2-by-2 factorial design. Early strut coverage was measured as the percentage of uncovered struts on 3-month follow-up OCT examination. The primary outcome was the difference in early strut coverage between EES and BES groups and between OCT- and angiography-guided implantation groups. The secondary outcome was a composite of cardiac death, myocardial infarction, stent thrombosis, and major bleeding during the first 12 months post-procedure in patients receiving 3-month DAPT based on the presence of early strut coverage (≤6% uncovered) on 3-month follow-up OCT. Three-month follow-up OCT data were acquired for 779 patients (87.1%). The median percentage of uncovered struts at 3 months was 8.9% and 8.2% in the EES and BES groups, respectively (p = 0.69) and was lower in the OCT-guided group (7.5%) than in the angiography-guided group (9.9%; p = 0.009). Favorable early strut coverage (≤6% uncovered strut) was observed in 320 of 779 patients (41.1%). At 12 months, the composite event rarely occurred in the 3-month (0.3%) or 12-month (0.2%) DAPT groups (p = 0.80). OCT-guided DES implantation improved early strut coverage compared with angiography-guided DES implantation, with no difference in strut coverage between EES and BES groups. Short-term DAPT may be feasible in selected patients with

Background: Anti-tumour necrosis factor (TNF)α treatments improve outcome in severe rheumatoid arthritis (RA) and are efficacious in psoriasis and psoriatic arthritis. However recent case reports describe psoriasis occurring as an adverse event in patients with RA receiving anti-TNFα therapy. Objectives: We aimed to determine whether the incidence rate of psoriasis was higher in patients with RA treated with anti-TNFα therapy compared to those treated with traditional disease-modifying antirheumatic drugs (DMARDs). We also compared the incidence rates of psoriasis between the three anti-TNFα drugs licensed for RA. Methods: We studied 9826 anti-TNF-treated and 2880 DMARD-treated patients with severe RA from The British Society for Rheumatology Biologics Register (BSRBR). All patients reported with new onset psoriasis as an adverse event were included in the analysis. Incidence rates of psoriasis were calculated as events/1000 person years and compared using incidence rate ratios (IRR). Results: In all, 25 incident cases of psoriasis in patients receiving anti-TNFα therapy and none in the comparison cohort were reported between January 2001 and July 2007. The absence of any cases in the comparison cohort precluded a direct comparison; however the crude incidence rate of psoriasis in those treated with anti-TNFα therapy was elevated at 1.04 (95% CI 0.67 to 1.54) per 1000 person years compared to the rate of 0 (upper 97.5% CI 0.71) per 1000 person years in the patients treated with DMARDs. Patients treated with adalimumab had a significantly higher rate of incident psoriasis compared to patients treated with etanercept (IRR 4.6, 95% CI 1.7 to 12.1) and infliximab (IRR 3.5, 95% CI 1.3 to 9.3). Conclusions: Results from this study suggest that the incidence of psoriasis is increased in patients treated with anti-TNFα therapy. Our findings also suggest that the incidence may be higher in patients treated with adalimumab. PMID:18385277

Immunization of Children Receiving Immunosuppressive Therapy for Cancer or Hematopoietic Stem Cell Transplantation

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

Treatment-related hypertension (tHTN) is frequent during sunitinib treatment. However, data on risk factors and treatment of tHTN remain scarce. Patients with metastatic renal-cell carcinoma treated with sunitinib from June 2004 to December 2011 were included. Medical records were retrospectively analyzed for tHTN risk factors and antihypertensive treatments (AHT). Descriptive statistics, Cox regression, and competitive risk models were applied. A total of 51 (70.8%) of 72 patients developed tHTN after a median sunitinib treatment of 28 days. Mean blood pressure increased from 130/75 (range, 90 to 190/58 to 101) mm Hg on day 1 to 140/80 (range, 90 to 190/60 to 120, P < .001) mm Hg on day 28. Standard dose of sunitinib, age > 50 years, and prehypertension were identified as independent risk factors for tHTN. Thirty-eight patients (72.5%) in the tHTN subgroup received modification of AHT. Calcium channel blockers (CCB) were identified as the best at controlling tHTN compared to other drugs (P = .045). The combination of AHT was more potent than a dose increase of a single-drug AHT, and early AHT intervention was more efficacious than delayed start of therapy. Patients at risk for tHTN require more rigorous blood pressure measurement. CCB seemed to be most potent and efficient, and an early combination of different classes of AHT was more efficacious than full-dose, single-agent AHT. Copyright © 2016 Elsevier Inc.

Randomized trials have shown a local control benefit with adjuvant radiotherapy (RT) in high-intermediate-risk endometrial cancer patients, although not all such patients receive RT. We reviewed the National Cancer Data Base to investigate which patient/tumor-related factors are associated with delivery of adjuvant RT. The National Cancer Data Base was queried for patients diagnosed with International Federation of Gynecology and Obstetrics 2009 stage I endometrioid adenocarcinoma from 1998 to 2012 who underwent surgery +/- adjuvant RT. Exclusion criteria were unknown stage/grade, nonsurgical primary therapy, less than 30 days' follow-up, RT of more than 6 months after surgery, or palliative treatment. High-intermediate risk was defined based on Post Operative Radiation Therapy in Endometrial Carcinoma 2 criteria: older than 60 years with stage IA grade 3 or stage IB grade 1-2. Seventeen thousand five hundred twenty-four met inclusion criteria, and the 13,651 patients with complete data were subjected to a multiple logistic regression analysis; 7814 (57.2%) received surgery alone, and 5837 (42.8%) received surgery + RT. Receipt of adjuvant RT was more likely among black women and women with higher income, Northeastern residence, diagnosis after 2010, greater than 50% myometrial invasion, and receipt of adjuvant chemotherapy (P < 0.05). Patients older than 80 years or those undergoing lymph node dissection were less likely to receive adjuvant RT (P < 0.05). Of those treated with RT, 44.0% received external beam therapy, 54.8% received vaginal cuff brachytherapy, and 0.6% received both. Among irradiated women, patients older than 80 years and those with Northeastern residence, treatment at academic facilities, diagnosis after 2004, and lymph node dissection were more likely to undergo brachytherapy over external beam radiation therapy (P < 0.05). Overall use of adjuvant RT was 28.8% between 1998 and 2004, 42.0% between 2005 and 2010, and 43.4% between 2011 and 2012

Stroke is a major public health problem worldwide. There are limited data on national stroke prevalence and outcomes after the beginning of the thrombolytic therapy era in Thailand. This study aimed to investigate the prevalence and factors associated with mortality in stroke patients in Thailand using the national reimbursement databases. Clinical data retrieved included individuals under the universal coverage, social security, and civil servant benefit systems between 1 October 2009 and 30 September 2010. The stroke diagnosis code was based on the International Classification of Diseases 10th revision system including G45 (transient cerebral ischemic attacks and related syndromes), I61 (intracerebral hemorrhage), and I63 (cerebral infarction). The prevalence and stroke outcomes were calculated from these coded data. Factors associated with death were evaluated by multivariable logistic regression analysis. We found that the most frequent stroke subtype was cerebral infarction with a prevalence of 122 patients per 100,000 of population, an average length of hospital stay of 6.8 days, an average hospital charge of 20,740 baht (∼$USD 691), a mortality rate of 7%, and thrombolytic prescriptions of 1%. The significant factors associated with stroke mortality were septicemia, pulmonary embolism, pneumonia, myocardial infarction, status epilepticus, and heart failure. In conclusion, the prevalence and outcomes of stroke in Thailand were comparable with other countries. The era of thrombolytic therapy has just begun in Thailand. Copyright © 2014 Elsevier Ltd.

Thrombotic events affect many individuals in a number of ways, all of which can cause significant morbidity and mortality. Nattokinase (NK), as a novel thrombolytic drug, has been used for thrombolytic therapy. It not only possesses plasminogen activator activity, but also directly digests fibrin through limited proteolysis. However, it may undergo inactivation and denaturation in the harsh external environment. In this study, a multiarm-polyethylene glycol-polyglutamic acid peptide dendrimer was fabricated and used as a carrier for NK protection and delivery. Different arm numbers of polyethylene glycol-polyglutamic acid peptide dendrimers (x-PEG(G 3 ) x , x = 2, 4, 6, 8) were designed, prepared, and characterized by 1 H NMR and FTIR. Then, x-PEG(G 3 ) x were loaded with NK to form nanocomposites. Their size and morphology were determined by dynamic light scattering and transmission electron microscopy. Enzyme activity was evaluated via UV-Vis absorbance spectra, fluorescence spectra, circular dichroism spectra, and zeta potential measurements. The study reveals that the obtained x-PEG(G 3 ) x /NK nanocomposites possess high enzyme activity. In addition, the nanocomposites show increased viability of rat macrophage cells, and excellent thrombolysis ability in vitro and in vivo. This work establishes a multiarm-polyethylene glycol-polyglutamic acid peptide dendrimer with potential application in NK carrier and thrombolytic therapy. © 2018 Wiley Periodicals, Inc.

Purpose: To review outcomes of locally advanced pancreatic cancer (LAPC) patients treated with dose-escalated intensity modulated radiation therapy (IMRT) with curative intent. Methods and Materials: A total of 200 patients with LAPC were treated with induction chemotherapy followed by chemoradiation between 2006 and 2014. Of these, 47 (24%) having tumors >1 cm from the luminal organs were selected for dose-escalated IMRT (biologically effective dose [BED] >70 Gy) using a simultaneous integrated boost technique, inspiration breath hold, and computed tomographic image guidance. Fractionation was optimized for coverage of gross tumor and luminal organ sparing. A 2- to 5-mm margin around the gross tumor volume wasmore » treated using a simultaneous integrated boost with a microscopic dose. Overall survival (OS), recurrence-free survival (RFS), local-regional and distant RFS, and time to local-regional and distant recurrence, calculated from start of chemoradiation, were the outcomes of interest. Results: Median radiation dose was 50.4 Gy (BED = 59.47 Gy) with a concurrent capecitabine-based (86%) regimen. Patients who received BED >70 Gy had a superior OS (17.8 vs 15.0 months, P=.03), which was preserved throughout the follow-up period, with estimated OS rates at 2 years of 36% versus 19% and at 3 years of 31% versus 9% along with improved local-regional RFS (10.2 vs 6.2 months, P=.05) as compared with those receiving BED ≤70 Gy. Degree of gross tumor volume coverage did not seem to affect outcomes. No additional toxicity was observed in the high-dose group. Higher dose (BED) was the only predictor of improved OS on multivariate analysis. Conclusion: Radiation dose escalation during consolidative chemoradiation therapy after induction chemotherapy for LAPC patients improves OS and local-regional RFS.« less

Neoadjuvant radiotherapy has the potential to improve local disease control for patients with localized pancreatic cancers. Concern about an increased risk of surgical complications due to small bowel and gastric exposure, however, has limited enthusiasm for this approach. Dosimetric studies have demonstrated the potential for proton therapy to reduce intestinal exposure compared with X-ray-based therapy. We sought to determine if neoadjuvant proton therapy allowed for field expansions to cover high-risk nodal stations in addition to the primary tumor. Twelve consecutive patients with nonmetastatic cancers of the pancreatic head underwent proton-based planning for neoadjuvant radiotherapy. Gross tumor volume was contoured using diagnostic computed tomography (CT) scans with oral and intravenous contrast. Four-dimensional planning scans were utilized to define an internal clinical target volume (ICTV). Five-mm planning target volume (PTV) expansions on the ICTV were generated to establish an initial PTV (PTV1). A second PTV was created using the initial PTV but was expanded to include the high-risk nodal targets as defined by the RTOG contouring atlas (PTV2). Optimized proton plans were generated for both PTVs for each patient. All PTVs received a dose of 50.4 cobalt gray equivalent (CGE). Normal-tissue exposures to the small bowel space, stomach, right kidney, left kidney and liver were recorded. Point spinal cord dose was limited to 45 CGE. Median PTV1 volume was 308.75 cm(3) (range, 133.33-495.61 cm(3)). Median PTV2 volume was 541.75 cm(3) (range, 399.44-691.14 cm(3)). In spite of the substantial enlargement of the PTV when high-risk lymph nodes were included in the treatment volume, normal-tissue exposures (stomach, bowel space, liver, and kidneys) were only minimally increased relative to the exposures seen when only the gross tumor target was treated. Proton therapy appears to allow for field expansions to cover high-risk lymph nodes without significantly

BACKGROUND The purpose of this study was to determine whether racial disparities in cancer therapy had diminished since the time they were initially documented in the early 1990s. METHODS The authors identified a cohort of patients in the SEER-Medicare linked database who were ages 66 to 85 years and who had a primary diagnosis of colorectal, breast, lung, or prostate cancer during 1992 through 2002. The authors identified 7 stage-specific processes of cancer therapy by using Medicare claims. Candidate covariates in multivariate logistic regression included year, clinical, and sociodemographic characteristics, and physician access before cancer diagnosis. RESULTS During the full study period, black patients were significantly less likely than white patients to receive therapy for cancers of the lung (surgical resection of early stage, 64.0% vs 78.5% for blacks and whites, respectively), breast (radiation after lumpectomy, 77.8% vs 85.8%), colon (adjuvant therapy for stage III, 52.1% vs 64.1%), and prostate (definitive therapy for early stage, 72.4% vs 77.2%, respectively). For both black and white patients, there was little or no improvement in the proportion of patients receiving therapy for most cancer therapies studied, and there was no decrease in the magnitude of any of these racial disparities between 1992 and 2002. Racial disparities persisted even after restricting the analysis to patients who had physician access before their diagnosis. CONCLUSIONS There has been little improvement in either the overall proportion of Medicare beneficiaries receiving cancer therapies or the magnitude of racial disparity. Efforts in the last decade to mitigate cancer therapy disparities appear to have been unsuccessful. PMID:18181101

The aim of this investigation was to identify factors associated with HIV transmission risk behavior among HIV-positive women and men receiving antiretroviral therapy (ART) in KwaZulu-Natal, South Africa. Across 16 clinics, 1,890 HIV+ patients on ART completed a risk-focused audio computer-assisted self-interview upon enrolling in a prevention-with-positives intervention trial. Results demonstrated that 62 % of HIV-positive patients' recent unprotected sexual acts involved HIV-negative or HIV status unknown partners. For HIV-positive women, multivariable correlates of unprotected sex with HIV-negative or HIV status unknown partners were indicative of poor HIV prevention-related information and of sexual partnership-associated behavioral skills barriers. For HIV-positive men, multivariable correlates represented motivational barriers, characterized by negative condom attitudes and the experience of depressive symptomatology, as well as possible underlying information deficits. Findings suggest that interventions addressing gender-specific and culturally-relevant information, motivation, and behavioral skills barriers could help reduce HIV transmission risk behavior among HIV-positive South Africans.

Antiretroviral therapy has been shown to reduce rates of congenital CMV infection. Little information is available on the possible impact of antiretroviral therapy on postnatal breastfeeding-associated CMV infection acquisition. A cohort of 89 HIV-infected mothers and their children was studied. Women received antiretroviral therapy from week 25 of gestation until 6 months postpartum or indefinitely if meeting the criteria for treatment. All women were evaluated for CMV IgG presence and CMV DNA in breast milk. Children were tested for CMV infection by either the presence of IgM or the presence of CMV DNA in plasma at 1, 6 and 12 months and by the presence of IgG at 24 months. All mothers had high titers of CMV DNA in breast milk (5.7 log at Month 1 and 5.1 log at Month 6). Cumulative CMV infection rates were 60.3 % at Month 6, 69 % at Month 12 and 96.4 % at Month 24. There was a significant negative correlation between the duration of antiretroviral treatment during pregnancy and levels of CMV DNA in breast milk at Month 1 (P = 0.033). There was a trend for a correlation between high titers of CMV DNA in breast milk at 6 months and CMV infection at 6 months (P = 0.069). In this cohort, more than 95 % of the children had acquired CMV infection by 2 years of age. Besides breastfeeding, which played a major role, also horizontal transmission between 1 and 2 years was certainly relevant in determining CMV infection acquisition.

To investigate the effectiveness of cryoprecipitate in the comprehensive conservative therapy of patients with acute purulent pyelonephritis. We conducted a retrospective analysis of medical records of patients who were diagnosed with acute non-obstructive pyelonephritis from 2007to 2015. During this period, a total of 3912 patients with acute non-obstructive pyelonephritis were treated at the Department of Urology. Patients were assigned to either receive or not receive cryoprecipitate in the comprehensive conservative therapy. The comprehensive conservative therapy of both groups included antibacterial agents, detoxification, anti-inflammatory therapy. In the study group, patients received additional treatment with cryoprecipitate. By that way we estimated the number of patients who avoided surgery in both groups. There were 3912 patients divided into two groups. The first group included 756 patients (19.3%) who received cryoprecipitate in the comprehensive therapy of pyelonephritis. Of them, 735 patients (97.3%) did not require surgical treatment, and only 21 patients (2.7%) underwent surgery. The second group comprised 3156 patients (80.7%) who did not receive cryoprecipitate. Of them, 2974 patients (94.2%) were treated conservatively without surgical intervention and 182 patients (5.8%) received conservative therapy concurrently with surgical treatment. Therefore, including cryoprecipitate in the comprehensive conservative therapy of acute non-obstructive pyelonephritis results in twice smaller percentage of patients (2.7% vs 5.8%) requiring surgery compared to the comprehensive conservative therapy alone.

Effective rehabilitative therapies are needed for patients with long-term deficits after stroke. In this multicenter, randomized, controlled trial involving 127 patients with moderate-to-severe upper-limb impairment 6 months or more after a stroke, we randomly assigned 49 patients to receive intensive robot-assisted therapy, 50 to receive intensive comparison therapy, and 28 to receive usual care. Therapy consisted of 36 1-hour sessions over a period of 12 weeks. The primary outcome was a change in motor function, as measured on the Fugl-Meyer Assessment of Sensorimotor Recovery after Stroke, at 12 weeks. Secondary outcomes were scores on the Wolf Motor Function Test and the Stroke Impact Scale. Secondary analyses assessed the treatment effect at 36 weeks. At 12 weeks, the mean Fugl-Meyer score for patients receiving robot-assisted therapy was better than that for patients receiving usual care (difference, 2.17 points; 95% confidence interval [CI], -0.23 to 4.58) and worse than that for patients receiving intensive comparison therapy (difference, -0.14 points; 95% CI, -2.94 to 2.65), but the differences were not significant. The results on the Stroke Impact Scale were significantly better for patients receiving robot-assisted therapy than for those receiving usual care (difference, 7.64 points; 95% CI, 2.03 to 13.24). No other treatment comparisons were significant at 12 weeks. Secondary analyses showed that at 36 weeks, robot-assisted therapy significantly improved the Fugl-Meyer score (difference, 2.88 points; 95% CI, 0.57 to 5.18) and the time on the Wolf Motor Function Test (difference, -8.10 seconds; 95% CI, -13.61 to -2.60) as compared with usual care but not with intensive therapy. No serious adverse events were reported. In patients with long-term upper-limb deficits after stroke, robot-assisted therapy did not significantly improve motor function at 12 weeks, as compared with usual care or intensive therapy. In secondary analyses, robot-assisted therapy

Oral mucositis is a major event increasing treatment costs of head and neck squamous cell carcinoma (HNSCC) patients treated with chemoradiation (CRT). This study was designed to estimate the cost-effectiveness of low-level laser therapy (LLLT) to prevent oral mucositis in HNSCC patients receiving CRT. From June 2007 to December 2010, 94 patients with HNSCC of nasopharynx, oropharynx, and hypopharynx entered a prospective, randomized, double blind, placebo-controlled, phase III trial. CRT consisted of conventional radiotherapy (RT: 70.2 Gy, 1.8 Gy/d, 5 times/wk)+concurrent cisplatin (100mg/m2) every 3 weeks. An InGaAlP (660 nm-100 mW-4J/cm2) laser diode was used for LLLT. From the perspective of Brazil's public health care system (SUS), total costs were higher in Placebo Group (PG) than Laser Group (LG) for opioid use (LG=US$ 9.08, PG=US$ 44.28), gastrostomy feeding (LG=US$ 50.50, PG=US$ 129.86), and hospitalization (PG=US$ 77.03). In LG, the cost was higher for laser therapy only (US$ 1880.57). The total incremental cost associated with the use of LLLT was US$ 1689.00 per patient. The incremental cost-effectiveness ratio (ICER) was US$ 4961.37 per grade 3-4 OM case prevented compared to no treatment. Our results indicate that morbidity was lower in the Laser Group and that LLLT was more cost-effective than placebo up to a threshold of at least US$ 5000 per mucositis case prevented. NCT01439724.

Empirically-supported and non-empirically supported therapies for bulimia nervosa: retrospective patient ratings

PubMed Central

2013-01-01

Background Empirically supported therapies for bulimia nervosa include cognitive behaviour therapy and interpersonal therapy. Whilst these treatments have been shown to be effective in multiple randomised controlled trials, little research has investigated how they are perceived by patients who receive them. This study investigated whether empirically-supported psychological therapies (ESTs) are associated with superior self-rated treatment outcomes in clients with Bulimia Nervosa (BN). Results 98 adults who had received psychological therapy for BN in the United Kingdom completed a questionnaire which retrospectively assessed the specific contents of their psychological therapy and self-rated treatment outcomes. Around half the sample, fifty three participants reported receiving an EST. Fifty of these received Cognitive Behaviour Therapy (CBT) and three Interpersonal Therapy (IPT). Where therapy met expert criteria for Cognitive Behaviour Therapy for Bulimia Nervosa (CBT-BN, an EST) participants reported superior treatment outcomes than those who appeared to receive non-specialist cognitive-behavioural therapy. However, self-rated treatment outcomes were similar overall between those whose therapy met criteria for ESTs and those whose therapy did not. Conclusions The findings offer tentative support for the perceived helpfulness of CBT-BN as evaluated in controlled research trials. Cognitive-behavioural therapies for BN, as they are delivered in the UK, may not necessarily be perceived as more beneficial by clients with BN than psychological therapies which currently have less empirical support.

Wu, Che-Wei

2017-01-01

Common complaints of patients who have received thyroidectomy include dysphonia (voice dysfunction) and dysphagia (difficulty swallowing). One cause of these surgical outcomes is recurrent laryngeal nerve paralysis. Many studies have discussed the effectiveness of speech therapy (e.g., voice therapy and dysphagia therapy) for improving dysphonia and dysphagia, but not specifically in patients who have received thyroidectomy. Therefore, the aim of this paper was to discuss issues regarding speech therapy such as voice therapy and dysphagia for patients after thyroidectomy. Another aim was to review the literature on speech therapy for patients with recurrent laryngeal nerve paralysis after thyroidectomy. Databases used for the literature review in this study included, PubMed, MEDLINE, Academic Search Primer, ERIC, CINAHL Plus, and EBSCO. The articles retrieved by database searches were classified and screened for relevance by using EndNote. Of the 936 articles retrieved, 18 discussed “voice assessment and thyroidectomy”, 3 discussed “voice therapy and thyroidectomy”, and 11 discussed “surgical interventions for voice restoration after thyroidectomy”. Only 3 studies discussed topics related to “swallowing function assessment/treatment and thyroidectomy”. Although many studies have investigated voice changes and assessment methods in thyroidectomy patients, few recent studies have investigated speech therapy after thyroidectomy. Additionally, some studies have addressed dysphagia after thyroidectomy, but few have discussed assessment and treatment of dysphagia after thyroidectomy. PMID:29142841

Background Antiarrhythmic drugs (AAD) and anticoagulation are mainstays of atrial fibrillation (AF) treatment. Objective We aimed to study the use and outcomes of AAD therapy in anticoagulated AF patients. Methods Patients in the ROCKET AF trial (n=14,264) were grouped by AAD use at baseline: amiodarone, other AAD, or no AAD. Multivariable adjustment was performed to compare stroke, bleeding, and death across groups, as well as across treatment assignment (rivaroxaban or warfarin). Results Of 14,264 patients randomized, 1681 (11.8%) were treated with an AAD (1144 [8%] with amiodarone, 537 [3.8%] with other AADs). Amiodarone-treated patients were less-often female (38% vs. 48%), had more persistent AF (64% vs. 40%), and more concomitant heart failure (71% vs. 41%) than patients receiving other AADs. Patients receiving no AAD more closely-resembled amiodarone-treated patients. Time in therapeutic range was significantly lower in warfarin-treated patients receiving amiodarone versus no AAD (50% vs. 58%, p<0.0001). Compared with no AAD, neither amiodarone (adjusted HR 0.98, 95% CI 0.74–1.31, p=0.9) nor other AADs (adjusted HR 0.66, 95% CI 0.37–1.17, p=0.15) were associated with increased mortality. Similar results were observed for embolic and bleeding outcomes. Rivaroxaban treatment effects in patients not on an AAD were consistent with the overall trial (primary endpoint adjusted HR 0.82, 95% CI 0.68–0.98, pinteraction=0.06; safety endpoint adjusted HR 1.12, 95% CI 0.90–1.24, pinteraction=0.33). Conclusion Treatment with AADs was not associated with increased morbidity or mortality in anticoagulated patients with AF. The influence of amiodarone on outcomes in patients receiving rivaroxaban requires further study. PMID:24833235

Background Fluid overload is known to be associated with increased mortality in patients with acute kidney injury (AKI) who are critically ill. In this study, we intended to uncover whether the adverse effect of fluid overload on survival could be applied to all of the patients with AKI who received continuous renal replacement therapy (CRRT). Methods We analyzed 341 patients with AKI who received CRRT in our intensive care units. The presence of fluid overload was defined as a minimum 10% increase in body weight from the baseline. Demographics, comorbid diseases, clinical data, severity of illness [the sequential organ failure assessment (SOFA) score, number of vasopressors, diagnosis of sepsis, use of ventilator] upon ICU admission, fluid overload status, and time elapsed from AKI diagnosis until CRRT initiation were reviewed from the medical charts. Results Patients with total fluid overload from 3 days before CRRT initiation to ICU discharge had a significantly lower survival rate after ICU admission, as compared to patients with no fluid overload (P < 0.001). Among patients with sepsis (P < 0.001) or with high SOFA scores (P < 0.001), there was a significant difference in survival of the patients with and without fluid overload. In patients without sepsis or with low SOFA score, there was no significant difference in survival of patients irrespective of fluid overload. Conclusion Our study demonstrates that the adverse effect of fluid overload on survival is more evident in patients with sepsis or with more severe illness, and that it might not apply to patients without sepsis or with less severe illness.

Choo, Richard; Lukka, Himu; Cheung, Patrick

Purpose: Androgen deprivation therapy (ADT) has been used as an adjuvant treatment to radiation therapy (RT) for the management of locally advanced prostate carcinoma. Long-term ADT decreases bone mineral density (BMD) and increases the risk of osteoporosis. The objective of this clinical trial was to evaluate the efficacy of risedronate for the prevention of BMD loss in nonmetastatic prostate cancer patients undergoing RT plus 2 to 3 years of ADT. Methods and Materials: A double-blinded, placebo-controlled, randomized trial was conducted for nonmetastatic prostate cancer patients receiving RT plus 2 to 3 years of ADT. All had T scores > −2.5more » on dual energy x-ray absorptiometry at baseline. Patients were randomized 1:1 between risedronate and placebo for 2 years. The primary endpoints were the percent changes in the BMD of the lumbar spine at 1 and 2 years from baseline, measured by dual energy x-ray absorptiometry. Analyses of the changes in BMD and bone turnover biomarkers were carried out by comparing mean values of the intrapatient changes between the 2 arms, using standard t tests. Results: One hundred four patients were accrued between 2004 and 2007, with 52 in each arm. Mean age was 66.8 and 67.5 years for the placebo and risedronate, respectively. At 1 and 2 years, mean (±SE) BMD of the lumbar spine decreased by 5.77% ± 4.66% and 13.55% ± 6.33%, respectively, in the placebo, compared with 0.12% ± 1.29% at 1 year (P=.2485) and 0.85% ± 1.56% (P=.0583) at 2 years in the risedronate. The placebo had a significant increase in serum bone turnover biomarkers compared with the risedronate. Conclusions: Weekly oral risedronate prevented BMD loss at 2 years and resulted in significant suppression of bone turnover biomarkers for 24 months for patients receiving RT plus 2 to 3 years of ADT.« less

Thrombolytic therapy for acute myocardial infarction standardly makes use of the medications streptokinase (SK) and tissue plasminogen activator (tPA). In this study, the potential of silica-coated magnetic nanoparticles (SiO2-MNPs) as nanocarriers clinical thrombolytic therapy was investigated. SiO2-MNPs for use in targeted therapeutic delivery of tPA and SK were prepared using a combined technique incorporating controlled precipitation and hydrothermal methods. Response surface methodology (RSM) was employed to evaluate the efficiency of the SiO2-MNPs. The production of SK secreted from Streptococcus equi was enhanced using random mutagenesis. The tPA and SK A were encapsulated by means of a silanizing agent with a surface rich in 3-aminopropyltrimethoxysilane layered around the SiO2-MNPs. Blood clot lysis assays and fibrin-containing agarose plates were used to carry out in vitro thrombolysis testing. The optimum conditions for producing MNPs were found to be at pH=13 and at a temperature of 75°C for 45 min. Culture conditions of 2.75% NaCl concentration at initial pH=7.5 for 90 s under UV resulted in maximum SK activity. The tPA/SK-conjugated SiO2-MNPs (SiO2-MNP-tPA-SK) increased operating stability in whole blood and storage stability in a buffer by 92%. More effective thrombolysis using magnetic targeting was indicated by a 38% reduction in blood clot lysis time achieved with SiO2-MNP-tPA-SK compared to administering the SiO2-MNPs without guidance. The silica-coated magnetic nanocarriers developed in this study show potential for improved clinical thrombolytic therapy. Copyright © 2015. Published by Elsevier B.V.

Thyroid dysfunction is prevalent in patients with heart failure (HF) and hypothyroidism is related to the adverse prognosis of HF subjects receiving cardiac resynchronization therapy (CRT). We aim to investigate whether low-normal free triiodothyronine (fT3) level is related to CRT response and the prognosis of euthyroid patients with HF after CRT implantation.One hundred and thirteen euthyroid patients who received CRT therapy without previous thyroid disease and any treatment affecting thyroid hormones were enrolled. All of patients were evaluated for cardiac function and thyroid hormones (serum levels of fT3, free thyroxine [fT4] and thyroid-stimulating hormone [TSH]). The end points were overall mortality and hospitalization for HF worsening. During a follow-up period of 39 ± 3 weeks, 36 patients (31.9%) died and 45 patients (39.8%) had hospitalization for HF exacerbation. A higher rate of NYHA III/IV class and a lower fT3 level were both observed in death group and HF event group. Multivariate Cox regression analyses disclosed that a lower-normal fT3 level (HR = 0.648, P = 0.009) and CRT response (HR = 0.441, P = 0.001) were both independent predictors of overall mortality. In addition, they were also both related to HF re-hospitalization event (P < 0.01 for both). Patients with fT3 < 3.00 pmol/L had a significantly higher overall mortality than those with fT3 ≥ 3.00 pmol/L (P = 0.027). Meanwhile, a higher HF hospitalization event rate was also found in patients with fT3 < 3.00 pmol/L (P < 0.001).A lower-normal fT3 level is correlated with a worse cardiac function an adverse prognosis in euthyroid patients with HF after CRT implantation.

Pulmonary physiology during pulmonary embolism.

PubMed

Elliott, C G

1992-04-01

Acute pulmonary thromboembolism produces a number of pathophysiologic derangements of pulmonary function. Foremost among these alterations is increased pulmonary vascular resistance. For patients without preexistent cardiopulmonary disease, increased pulmonary vascular resistance is directly related to the degree of vascular obstruction demonstrated on the pulmonary arteriogram. Vasoconstriction, either reflexly or biochemically mediated, may contribute to increased pulmonary vascular resistance. Acute pulmonary thromboembolism also disturbs matching of ventilation and blood flow. Consequently, some lung units are overventilated relative to perfusion (increased dead space), while other lung units are underventilated relative to perfusion (venous admixture). True right-to-left shunting of mixed venous blood can occur through the lungs (intrapulmonary shunt) or across the atrial septum (intracardiac shunt). In addition, abnormalities of pulmonary gas exchange (carbon monoxide transfer), pulmonary compliance and airway resistance, and ventilatory control may accompany pulmonary embolism. Thrombolytic therapy can reverse the hemodynamic derangements of acute pulmonary thromboembolism more rapidly than anticoagulant therapy. Limited data suggest a sustained benefit of thrombolytic treatment on the pathophysiologic alterations of pulmonary vascular resistance and pulmonary gas exchange produced by acute pulmonary emboli.

Acute stroke therapy took a major step forward in 1996 after the approval of Intravenous (IV) tissue plasminogen activator (t-PA) by the US Food and Drug Administration for patients presenting within 3 hours of the onset of stroke symptoms. Since that time, there have been considerable advances in imaging techniques as well as the advent of devices to help in the management of acute stroke patients. As a result, the arsenal to treat acute stroke has grown, and the field of stroke as a subspecialty of neurology has emerged. Despite these advances, only 3% to 8% of eligible patients with acute stroke in the United States are administered thrombolytics.(1) We herein review the use of thrombolytics in stroke and provide an overview of the imaging advances, new devices, and recent trials that are shaping modern stroke therapy. Finally, we provide a practical approach to the management of acute stroke, specifically for the practicing cardiologist, who may encounter stroke during cardiac catheterization, post myocardial infarction (MI), and in a variety of other settings.

Pulmonary Embolism in 2017: How We Got Here and Where Are We Going?

In the 1970s, both the Urokinase Pulmonary Embolism and Urokinase-Streptokinase Pulmonary Embolism trials began the quest to develop thrombolytic therapy for the treatment of acute massive and submassive pulmonary embolism (PE). The goals of these studies were the immediate reduction in clot burden, restoration of hemodynamic stability, and improved survival. Major bleeding became the major barrier for clinicians to employ these therapies. From 1980s to the present time, a number of studies using recombinant tissue-type plasminogen activator for achieving these same above outcomes were completed but major bleeding continued to remain an adoption barrier. Finally, the concept of bringing the thrombolytic agent into the clot has entered the quest for the Holy Grail in the treatment of PE. This article will review all the major trials using peripheral thrombolysis and provide insight into the need for a team approach to pulmonary care (Pulmonary Embolism Response Team), standardization of pulmonary classification, and the need for trials designed for both short- and long-term outcomes using thrombolysis for selected PE populations.

Summary Reports of cerebral transluminal angioplasty and stenting in patients with vertebrobasilar ischemic stroke are scanty. Herein we report on the use of “monorail” coronary balloon angioplasty and stent balloon mounted catheters in two patients with acute vertebrobasilar ischemic stroke, focussing on the differences and possible advantages of the “monorail” technique in comparison with the “over-the-wire” technique. In both patients, the clinical picture was characterized by progressive brainstem symptoms followed by acute loss of consciousness related to an atherothrombotic occlusion and subocclusion of the dominant intracranial vertebral artery, respectively. In one patient, superselective thrombolytic therapy and balloon angioplasty resulted in a dissection flap at the vertebrobasilar junction. The latter was treated by successful deployment of a coronary stent. In the other patient, the subocclusive lesion was directly treated by angioplasty and stenting without thrombolytic therapy. The clinical outcome was poor for one patient (“locked in” syndrome) while the other had a complete clinical recovery. In acute atherothrombotic vertebrobasilar stroke transluminal cerebral angioplasty and stenting may be successfully performed allowing vessel recanalization. PMID:20594522

[Brain protection against cerebral ischemia].

Previous clinical trials failed to show the benefit of several potentially protective drugs in acute ischemic stroke. However, there would be three main approaches for brain protection against stroke. The first is to develop a novel thrombolytic agent which is more efficient and safer than alteplase. Tenecteplase and desmoteplase are in progress as a new thrombolytic drug. The second strategy is to augment collateral circulation through leptomeningeal anastomosis. Administration of G-CSF could enhance arteriogenesis, but it takes several days to develop functional collateral. For this purpose, partial aortic balloon clumping or stimulation of pterygopalatine ganglion may be promising. The third one is to protect neurovascular unit against reperfusion injury. Brain hypothermia is the most effective strategy in experimental ischemia, and the clinical trial for hypothermia combined with thrombolysis therapy is in progress. Activation of endogenous protective response, as presented by ischemic tolerance, has focused on remote ischemic conditioning. Although the precise mechanisms of remote preconditioning remain unclear, intermittent limb ischemia is a safe approach. Remote ischemic conditioning is now investigated in acute patients with thrombolysis therapy.

Purpose: To report the clinical outcomes of chemoradiotherapy (CRT) for anal carcinoma in human immunodeficiency virus (HIV)-infected patients receiving highly active antiretroviral therapy. Patients and Methods: Between 1997 and 2008, 21 HIV-positive patients who were receiving highly active antiretroviral therapy were treated with CRT (50.4 Gy at 1.8 Gy/fraction plus a 5.4-10.8-Gy external boost; 5-fluorouracil, 1,000 mg/m{sup 2}, Days 1-4 and 29-32; and mitomycin C, 10 mg/m{sup 2}, Days 1 and 29). A retrospective analysis was performed with respect to the tumor response, local control, cancer-specific and overall survival, and toxicity. The immunologic parameters, including pre- and post-treatment CD4 count,more » viral load, and acquired immunodeficiency syndrome-specific morbidity was recorded during follow-up (median, 53 months; range, 10-99). Results: CRT could be completed in all 21 patients with a reduction in the chemotherapy dose and/or interruption of radiotherapy in 5 and 5 cases, respectively. Acute Grade 3 toxicity occurred in 8 (38%) of the 21 patients. A complete response was achieved in 17 patients (81%), and tumor persistence or early progression was noted in 4 (19%). Six patients (29%) died, 5 of cancer progression and 1 of treatment-related toxicity. The 5-year local control, cancer-specific, and overall survival rate was 59%, 75%, and 67%, respectively. The median CD4 count significantly decreased from 347.5 cells/muL before CRT to 125 cells/muL 3-7 weeks after CRT completion (p <.001). In 6 (32%) of 19 patients, an increase of the HIV viral load was noted. Both parameters returned to the pretreatment values with additional follow-up. Conclusion: Our data have confirmed that in the highly active antiretroviral therapy era, HIV-related anal cancer can be treated with standard CRT without dose reductions. Close surveillance of the immunologic parameters is necessary.« less

Ellsworth, Susannah G.; Alcorn, Sara R., E-mail: salcorn2@jhmi.edu; Hales, Russell K.

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 patientsmore » (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.« less

Summary Injection drug users bear the burden of HIV in Vietnam and are a focus of national treatment programs. To date, determinants of successful therapy in this population are unknown. Substance use and clinical correlates of viral suppression were studied in 100 HIV-1 infected drug users receiving antiretroviral therapy (ART) for at least 6 months in Hanoi, Vietnam. Mean age of the cohort was 29.9 + 4.9 years; all were men. A majority of patients (73%) achieved viral suppression (HIV-RNA < 1000 copies/ml). Correlates of viral suppression include self-reported >95% adherence (p<0.01) and current use of trimethoprim/sulfamethoxazole (p<0.01); current or ever diagnosed with tuberculosis was associated with viral non-suppression (p=0.006). Tobacco use was prevalent (84%), and surprisingly 48% of patients reported active drug use; neither was associated with viral non-suppression. This is the first study to document successful ART treatment in a population of Vietnamese drug users; rates of viral suppression are comparable to other international populations. The 28% of patients without HIV-1 suppression highlights the need for adherence promotion, risk reduction programs, and population based surveillance strategies for assessing the emergence of HIV drug resistance in settings where access to viral load and drug resistance testing is limited.

Zeraati, Fatemeh; Homayounfar, Shahram; Esna-Ashari, Farzaneh; Khalili, Marzieh

2014-01-01

Background: The door-to-needle-time (DNT) is considered a standard time for scheduling thrombolysis for acute ST-segment elevation of myocardial infarction and this time can be reduced by minimizing the delay in starting thrombolytic treatment once the patient has reached to the hospital. This study was carried out on a sample of Iranian patients with acute myocardial infarction to determine the DNT in those after changing schedule of thrombolysis during 8 years from emergency to coronary care unit (CCU). Methods: A descriptive cross-sectional study was carried out on all consecutive patients with a confirmed diagnosis of acute myocardial infarction admitted to the emergency ward of Ekbatan Hospital in Hamadan, Iran, within 2011 and had an indication of fibrinolytic therapy, which 47 patients were finally indicated to receive streptokinase in the part of CCU. Results: The mean time interval between arrival at the hospital and electrocardiogram (ECG) assessment was 6.30 min, taking ECG and patient's admission was 21.6 min and transferring the patient from admission to CCU ward was 31.9. The time between transferring the patients to CCU ward and fibrinolytic administration order and the time between its ordering and infusion was 31.2 min and 14.0 min respectively. In sum, the DNT was estimated 84.48 ± 53.00 min ranged 30-325 min that was significantly more than standard DNT (P <0.01). Furthermore, DNT mean in this study is significantly more than a study conducted 8 years ago in the same hospital (P <0.01). Conclusions: The DNT is higher than the standard level and higher than the estimated level in the past. This shows that DNT was longer after transferring to CCU. PMID:24829715

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.

Background The effects of intra-aortic balloon pump (IABP) usage in patients with acute myocardial infarction remain controversial. This study sought to evaluate the outcomes of IABP usage in these patients. Methods Medline, EMBASE, and other internet sources were searched for relevant clinical trials. The primary efficacy endpoints (in-hospital, midterm, and long-term mortality) and secondary endpoints (reinfarction, recurrent ischemia, and new heart failure in the hospital) as well as safety endpoints (severe bleeding requiring blood transfusion and stroke in-hospital) were subsequently analyzed. Results Thirty-three clinical trials involving 18,889 patients were identified. The risk of long-term mortality in patients suffering from acute myocardial infarction was significantly decreased following IABP use (odds ratio [OR] 0.66, 95% confidence interval [CI]: 0.48–0.91, P=0.010). Both in-hospital and midterm mortality did not differ significantly between the IABP use group and no IABP use group (in-hospital: OR 0.87, 95% CI: 0.59–1.28, P=0.479; midterm: OR 1.12, 95% CI: 0.53–2.38, P=0.768). IABP insertion was not associated with the risk reduction of reinfarction, recurrent ischemia, or new heart failure. However, IABP use increased the risk of severe bleeding requiring blood transfusion (OR 2.05, 95% CI: 1.29–3.25, P=0.002) and stroke (OR 1.71, 95% CI: 1.04–2.82, P=0.035). In the thrombolytic therapy and cardiogenic shock subgroups, reduced mortality rates following IABP use were observed. Conclusion IABP insertion is associated with feasible benefits with respect to long-term survival rates in patients suffering from acute myocardial infarction, particularly those suffering from cardiogenic shock and receiving thrombolytic therapy, but at the cost of higher incidence of severe bleeding and stroke.

The overall objective of the Polish guidelines for the prevention and treatment of venous thromboembolism is to increase patient benefit and safety by appropriate prevention and treatment of deep vein thrombosis and pulmonary embolism as well as proper management of the complications associated with antithrombotic and thrombolytic therapy. These guidelines apply to adult trauma, cancer, surgical, and medical patients as well as those at increased risk of venous thromboembolism. Specific recommendations have been formulated for pregnant women, patients requiring surgery while receiving long-term oral anticoagulant treatment, and patients undergoing regional anesthesia and/or analgesia. We systematically identified all current clinical practice guidelines concerning the prevention and/or treatment of venous thromboembolism and assessed their methodological quality using the AGREE instrument. We chose to update existing Polish guidelines by adapting the most recent high quality guidelines that we identified to Polish cultural and organizational setting rather than develop all recommendations de novo. We based our recommendations primarily on the 8th edition of the American College of Chest Physicians (ACCP) Evidence-Based Clinical Practice Guidelines on Antithrombotic and Thrombolytic Therapy and on the European Society of Cardiology (ESC) Guidelines on the Diagnosis and Management of Acute Pulmonary Embolism. To make recommendations regarding specific management issues that had not been addressed in ACCP guidelines, or whenever panel members felt they needed additional information to reach the decision we also consulted guidelines developed by other professional societies and organizations as well as additional sources of evidence. For each recommendation we explicitly assessed its relevance and applicability in the context of health care system in Poland. We adapted recommendations when necessary, explicitly stating the rationale for modification and judgements

The current investigation involved an attempt to develop a clinical procedure to decrease anxiety and increase responsiveness (assertion) of psychiatric inpatients of both sexes in mixed diagnostic categories and to evaluate the effectiveness of the procedure. Using a Solomon Four-Group Design, patients, matched on age, sex, and diagnosis, were assigned to one of the following conditions: (1) pretest, treatment, posttest; (2) pretest, no treatment, posttest; (3) treatment, posttest; or (4) no treatment, posttest. The Gambrill-Richey Assertive Inventory was used to assess patient Degree of Discomfort and Response Probability with and without assertion training therapy. Results indicated that (1) patients receiving assertion training therapy were less anxious and more responsive after treatment than before, (2) patients receiving assertion training therapy were less anxious and more responsive than were matched control subjects, (3) control subjects who received no assertion training therapy and who were pretested showed moderate significant gains on the posttest measure, (4) patients reported a greater reduction of anxiety than they did an increase in responsiveness, and (5) pretesting did not significantly influence posttest scores.

Percutaneous Portal Vein Access and Transhepatic Tract Hemostasis

Percutaneous portal vein interventions require minimally invasive access to the portal venous system. Common approaches to the portal vein include transjugular hepatic vein to portal vein access and direct transhepatic portal vein access. A major concern of the transhepatic route is the risk of postprocedural bleeding, which is increased when patients are anticoagulated or receiving pharmaceutical thrombolytic therapy. Thus percutaneous portal vein access and subsequent closure are important technical parts of percutaneous portal vein procedures. At present, various techniques have been used for either portal access or subsequent transhepatic tract closure and hemostasis. Regardless of the method used, meticulous technique is required to achieve the overall safety and effectiveness of portal venous procedures. This article reviews the various techniques of percutaneous transhepatic portal vein access and the various closure and hemostatic methods used to reduce the risk of postprocedural bleeding.

2012-01-01

Objective 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. Methods 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). Results Over 7.5 years, thirty (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). Conclusion 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 six refusal patients (16.6%) had a stroke mimic. PMID:23227830

testing (69.9%), received stroke education (58.8%), received dysphagia screening (56.7%), and received tissue plasminogen activator (among eligible patients) (39.8%). Between 2001-2004 (prototype phase) and 2005-2007 (implementation by state health departments), substantial improvement occurred in dysphagia screening, lipid testing, smoking cessation counseling, and antithrombotic therapy prescribed at discharge. These initial improvements indicate that a surveillance system to track and improve the quality of hospital-based stroke care can be led successfully by state health departments, although further evaluations over time are needed. Despite these improvements, additional increases are needed in adherence to these and other performance measures. Nearly 40% of stroke patients did not use EMS services for transport to hospitals, and no change occurred in the proportion of patients who arrived at the hospital in time to receive thrombolytic therapy for ischemic stroke. Patients who are not promptly transported to hospitals after symptom onset are ineligible for thrombolytic therapy and other timely interventions for acute stroke. Results from PCNASR indicate the need for additional public health measures to inform the public of the need for timely activation of EMS services for signs and symptoms of stroke. In addition, low rates of adherence to certain measures of stroke care underscore the need for continuing coordinated programs to improve stroke quality of care. Additional analyses are needed to assess improvements in adherence to guidelines over time.

To assess changes in the prevalence of otitis media, associated with the use of highly active antiretroviral therapy, in Brazilian human immunodeficiency virus (HIV) infected children. Division of otorhinolaryngology, Hospital das Clínicas, Sao Paulo University Medical School, Brazil. A cohort of 459 HIV-infected children aged below 13 years. The prevalence of otitis media and the serum cluster of differentiation four glycoprotein T lymphocyte count were compared for children receiving highly active antiretroviral therapy (with protease inhibitors) and those receiving standard antiretroviral therapy (without protease inhibitors). Otitis media was present in 33.1 per cent of the children. Children aged from zero years to five years 11 months receiving highly active antiretroviral therapy had a higher prevalence of acute otitis media (p=0.02) and a lower prevalence of chronic otitis media (p=0.02). Children who were receiving highly active antiretroviral therapy had a mean serum cluster of differentiation four glycoprotein T lymphocyte count greater than that of those who were receiving standard antiretroviral therapy (p<0.001). The use of highly active antiretroviral therapy in Brazilian HIV-infected children was associated with a lower prevalence of chronic otitis media.

Only 1-3% of ischemic stroke patients receive thrombolytic therapy. Provider barriers to adhering with guidelines recommending tPA delivery in acute stroke are not well known. The main objective of this study was to describe barriers to thrombolytic use in acute stroke care. Twenty-four hospitals were randomly selected and matched into 12 pairs. Barrier assessment occurred at intervention sites only, and utilized focus groups and structured interviews. A pre-specified taxonomy was employed to characterize barriers. Two investigators independently assigned themes to transcribed responses. Seven facilitators (three emergency physicians, two nurses, and two study coordinators) conducted focus groups and interviews of emergency physicians (65), nurses (62), neurologists (15), radiologists (12), hospital administrators (12), and three others (hospitalists and pharmacist). The following themes represented the most important external barriers: environmental and patient factors. Important barriers internal to the clinician included familiarity with and motivation to adhere to the guidelines, lack of self-efficacy and outcome expectancy. The following themes were not substantial barriers: lack of awareness of the existence of acute stroke guidelines, presence of conflicting guidelines, and lack of agreement with the guidelines. Healthcare providers perceive environmental and patient-related factors as the primary barriers to adherence with acute stroke treatment guidelines. Interventions focused on increasing physician familiarity with and motivation to follow guidelines may be of highest yield in improving adherence. Improving self-efficacy in performing guideline concordant care may also be useful.

Purpose: To determine how chemotherapy agents affect radiation dose parameters that correlate with acute hematologic toxicity (HT) in patients treated with pelvic intensity modulated radiation therapy (P-IMRT) and concurrent chemotherapy. Methods and Materials: We assessed HT in 141 patients who received P-IMRT for anal, gynecologic, rectal, or prostate cancers, 95 of whom received concurrent chemotherapy. Patients were separated into 4 groups: mitomycin (MMC) + 5-fluorouracil (5FU, 37 of 141), platinum ± 5FU (Cis, 32 of 141), 5FU (26 of 141), and P-IMRT alone (46 of 141). The pelvic bone was contoured as a surrogate for pelvic bone marrow (PBM) andmore » divided into subsites: ilium, lower pelvis, and lumbosacral spine (LSS). The volumes of each region receiving 5-40 Gy were calculated. The endpoint for HT was grade ≥3 (HT3+) leukopenia, neutropenia or thrombocytopenia. Normal tissue complication probability was calculated using the Lyman-Kutcher-Burman model. Logistic regression was used to analyze association between HT3+ and dosimetric parameters. Results: Twenty-six patients experienced HT3+: 10 of 37 (27%) MMC, 14 of 32 (44%) Cis, 2 of 26 (8%) 5FU, and 0 of 46 P-IMRT. PBM dosimetric parameters were correlated with HT3+ in the MMC group but not in the Cis group. LSS dosimetric parameters were well correlated with HT3+ in both the MMC and Cis groups.

Cryptococcal infections are responsible for significant morbidity and mortality in immunocompromised patients. Reports of these infections in patients on small molecular kinase inhibitors have not been widely reported in clinical trials. We describe one case of cryptococcal meningoencephalitis and one case of cryptococcal pneumonia in two patients who were receiving ibrutinib for chronic lymphocytic leukemia. Despite different sites of cryptococcal infection, both patients had similar presentations of acute illness. Patient 1 was worked up for health care-associated pneumonia, as well as acute sinusitis prior to the diagnosis of cryptococcal meningoencephalitis. He also had a more complex past medical history than patient 2. Patient 2 developed atrial fibrillation from ibrutinib prior to admission for presumed health care-associated pneumonia. Cryptococcal antigen testing was done sooner in this patient due to patient receiving high-dose steroids for the treatment of underlying hemolytic anemia. We conclude that patients who develop acute illness while receiving ibrutinib should be considered for cryptococcal antigen testing.

Development of a vancomycin dosing approach for critically ill patients receiving hybrid hemodialysis using Monte Carlo simulation.

Lewis, Susan J; Mueller, Bruce A

2018-01-01

Prolonged intermittent renal replacement therapy is an increasingly popular treatment for acute kidney injury in critically ill patients that runs at different flow rates and durations than conventional hemodialysis or continuous renal replacement therapies. Pharmacokinetic studies conducted in patients receiving prolonged intermittent renal replacement therapy are scarce; consequently, clinicians are challenged to dose antibiotics effectively. The purpose of this study was to develop vancomycin dosing recommendations for patients receiving prolonged intermittent renal replacement therapy. Monte Carlo simulations were performed in thousands of virtual patients derived from previously published demographic, pharmacokinetic, and dialytic information derived from critically ill patients receiving vancomycin and other forms of renal replacement therapy. We conducted "in silico" vancomycin pharmacokinetic/pharmacodynamics analyses in these patients receiving prolonged intermittent renal replacement therapy to determine what vancomycin dose would achieve vancomycin 24-h area under the curve (AUC 24h ) of 400-700 mg·h/L, a target associated with positive clinical outcomes. Nine different vancomycin dosing regimens were tested using four different, commonly used prolonged intermittent renal replacement therapy modalities. A dosing nomogram based on serum concentration data achieved after the third dose was developed to individualize vancomycin therapy. An initial vancomycin dose of 15 or 20 mg/kg immediately followed by 15 mg/kg after subsequent prolonged intermittent renal replacement therapy treatments achieved AUC 24h of ≥400 mg·h/L for ≥90% of patients regardless of prolonged intermittent renal replacement therapy duration, modality, or time of vancomycin dose relative to prolonged intermittent renal replacement therapy. Many patients experienced AUC 24h of ≥700 mg·h/L, but once the dosing nomogram was applied to serum concentrations obtained after

To report the first case of severe osteoporosis associated with a vertebral pathologic fracture and osteonecrosis of femoral heads in an HIV-infected man receiving inhaled corticosteroids and ritonavir-boosted antiretroviral therapy. We describe an HIV-infected man with severe osteoporosis, bilateral hip osteonecrosis, and secondary adrenal suppression, including detailed clinical, laboratory, and radiographic data, and review the related literature. A 60-year-old man with a 15-year history of HIV infection and a medical history of long-standing bronchiectasis treated with inhaled corticosteroids and hypogonadism treated with testosterone was referred to the endocrinology clinic after experiencing an osteoporotic vertebral fracture. He was taking ritonavir-boosted antiretroviral therapy. Osteonecrosis of both hips was also diagnosed, which required total hip replacement therapy. Laboratory evaluation revealed adrenal insufficiency due to increased effect of exogenous inhaled steroids and no other secondary causes of osteoporosis. A bone densitometry study showed osteoporosis of both hips and the lumbar spine. He was treated with intravenous pamidronate. During treatment, he developed bilateral femoral fractures after minor trauma. Given the potential for increased serum levels of inhaled corticosteroids in patients taking ritonavir-boosted highly active antiretroviral therapy, attention must be paid to the risk of bone loss in HIV-infected patients taking inhaled corticosteroids. Prescribing calcium and vitamin D supplementation and considering early osteoporosis screening are reasonable measures for this patient population. Interaction between inhaled corticosteroids and ritonavir may increase risk of hypothalamus-pituitary-adrenal axis suppression.

To evaluate the effectiveness of constraint-induced movement therapy (CIMT) and combined mirror therapy for inpatient rehabilitation of the patients with subacute stroke. Twenty-six patients with subacute stroke were enrolled and randomly divided into three groups: CIMT combined with mirror therapy group, CIMT only group, and control group. Two weeks of CIMT for 6 hours a day with or without mirror therapy for 30 minutes a day were performed under supervision. All groups received conventional occupational therapy for 40 minutes a day for the same period. The CIMT only group and control group also received additional self-exercise to substitute for mirror therapy. The box and block test, 9-hole Pegboard test, grip strength, Brunnstrom stage, Wolf motor function test, Fugl-Meyer assessment, and the Korean version of Modified Barthel Index were performed prior to and two weeks after the treatment. After two weeks of treatment, the CIMT groups with and without mirror therapy showed higher improvement (p<0.05) than the control group, in most of functional assessments for hemiplegic upper extremity. The CIMT combined with mirror therapy group showed higher improvement than CIMT only group in box and block test, 9-hole Pegboard test, and grip strength, which represent fine motor functions of the upper extremity. The short-term CIMT combined with mirror therapy group showed more improvement compared to CIMT only group and control group, in the fine motor functions of hemiplegic upper extremity for the patients with subacute stroke.

Schistosomiasis control programmes are generally based on mass distribution of praziquantel (PZQ). This approach has been further strengthened by studies that demonstrated reduction in schistosomiasis-related morbidity following regular use of PZQ. Many women were excluded from this therapy when pregnant. Since a high degree of parity is achieved in many schistosomiasis-endemic regions, excluded women often miss treatment and consequently the beneficial effect of this therapy. This study investigated the effect of PZQ therapy on pregnancy in the Gezira region of Sudan. As part of the Blue Nile Health Project, more than 320,000 individuals received annual treatment with PZQ from 1980 to 1990. The present study reviewed the treatment records of all women between 1990 and 1995 in four villages. Eighty-eight of 637 women interviewed had received PZQ during their pregnancy. The outcome and the effect of PZQ therapy on their offspring were compared with a group of 549 women who had not received the drug during pregnancy. There were no significant differences between the two groups in the rate of abortion or preterm deliveries. No congenital abnormalities were noted by clinical examination in any of the babies born to either group. This retrospective study suggested that PZQ therapy is safe during pregnancy.

Central venous tunnelled hemodialysis catheters (CVTC) are used for initial vascular access in patients with renal failure. Tip design of the CVTC may play an important role in catheter function and complication rates, influencing adequate hemodialysis treatment of these patients. This prospective, observational cohort study compared the function and complication rates of two CVTCs in patients with end stage renal disease (ESRD) within a follow-up period of 24 months. The study included patients with ESRD who received either a CVTC with a split tip (ST) or a shotgun tip (SG). All patients underwent dialysis within 24 h of intervention. Blood flow was documented initially (Qb 0 ) and was followed up after 6 (Qb 6 ), 12 (Qb 12 ), and 24 (Qb 24 ) months. Analysis of blood flow and complication rates within the follow-up period was performed by questionnaires. In total, 185 patients were included, of whom 93 received a ST CVTC and 92 a SG CVTC. Baseline parameters did not differ significantly between groups. CVTC blood flow was not significantly different between the two devices. Thrombolytic therapy with Alteplase was used significantly more often in the ST group (29%) than in the SG group (16%) (p < 0.05). The CVTC replacement rate was significantly higher in the ST group (19.3%) compared with the SG group (8.7%) (p < 0.05). The tip design of CVTC (split or shotgun) appears to be irrelevant for long-term blood flow during dialysis treatment. However, patients may benefit from SG catheters over ST catheters where replacement rates and thrombolytic treatment are concerned. Copyright © 2016 European Society for Vascular Surgery.

The Diabetes Control and Complications Trial (DCCT) showed a beneficial effect of 6.5 years of intensive glycemic control on retinopathy in patients with type 1 diabetes. Between 1983 and 1989, a total of 1441 patients with type 1 diabetes in the DCCT were randomly assigned to receive either intensive diabetes therapy or conventional therapy aimed at preventing hyperglycemic symptoms. They were treated and followed until 1993. Subsequently, 1375 of these patients were followed in the observational Epidemiology of Diabetes Interventions and Complications (EDIC) study. The self-reported history of ocular surgical procedures was obtained annually. We evaluated the effect of intensive therapy as compared with conventional therapy on the incidence and cost of ocular surgery during these two studies. Over a median follow-up of 23 years, 130 ocular operations were performed in 63 of 711 patients assigned to intensive therapy (8.9%) and 189 ocular operations in 98 of 730 patients assigned to conventional therapy (13.4%) (P<0.001). After adjustment for DCCT baseline factors, intensive therapy was associated with a reduction in the risk of any diabetes-related ocular surgery by 48% (95% confidence interval [CI], 29 to 63; P<0.001) and a reduction in the risk of all such ocular procedures by 37% (95% CI, 12 to 55; P=0.01). Forty-two patients who received intensive therapy and 61 who received conventional therapy underwent cataract extraction (adjusted risk reduction with intensive therapy, 48%; 95% CI, 23 to 65; P=0.002); 29 patients who received intensive therapy and 50 who received conventional therapy underwent vitrectomy, retinal-detachment surgery, or both (adjusted risk reduction, 45%; 95% CI, 12 to 66; P=0.01). The costs of surgery were 32% lower in the intensive-therapy group. The beneficial effects of intensive therapy were fully attenuated after adjustment for mean glycated hemoglobin levels over the entire follow-up. Intensive therapy in patients with type 1

In addition to antiretroviral therapy, non-antiretroviral drugs are necessary for the appropriate care of people living with HIV. The costs of such drugs are totally or partially supported by the people living with HIV. We aimed to evaluate the overall costs, the costs supported by the people living with HIV and factors associated with the prescription of non-antiretroviral drugs in people living with HIV on antiretroviral therapy in Senegal. We conducted a retrospective cohort study on 331 people living with HIV who initiated antiretroviral therapy between 2009 and 2011 and followed until March 2012. The costs of non-antiretroviral drugs were those of the national pharmacy for essential drugs; otherwise they were the lowest costs in the private pharmacies. Associated factors were identified through a logistic regression model. The study population was 61 % female. At baseline, 39 % of patients were classified at WHO clinical stage 3 and 40 % at WHO clinical stage 4. Median age, body mass index and CD4 cells count were 41 years, 18kg/m 2  and 93 cells/μL, respectively. After a mean duration of 11.4 months of antiretroviral therapy, 85 % of patients received at least one prescription for a non-antiretroviral drug. Over the entire study period, the most frequently prescribed non-antiretroviral drugs were cotrimoxazole (78.9 % of patients), iron (33.2 %), vitamins (21.1 %) and antibiotics (19.6 %). The mean cost per patient was 34 Euros and the mean cost supported per patient was 14 Euros. The most expensive drugs per treated patient were antihypertensives (168 Euros), anti-ulcer agents (12 Euros), vitamins (8.5 Euros) and antihistamines (7 Euros). The prescription for a non-antiretroviral drug was associated with advanced clinical stage (WHO clinical stage 3/4 versus stage 1/2): OR=2.25; 95 % CI=1.11-4.57 and viral type (HIV-2 versus HIV-1/HIV-1+HIV-2): OR=0.36; 95 % CI=0.14-0.89.

To evaluate the development of phenotypic and genotypic resistance to zidovudine, didanosine and nevirapine as a function of the virologic response to therapy in a group of drug-naive individuals receiving various combinations of these agents. All patients were enrolled in a double-blind controlled randomized trial (the INCAS study) and were selected for detailed resistance studies based on specimen availability and virologic response. Within the three study groups (zidovudine/nevirapine, zidovudine/didanosine or zidovudine/nevirapine/didanosine), 16, 19 and 24 patients, respectively, had evaluable baseline isolates and remained in the study > 24 weeks. Phenotypic resistance to all three drugs was evaluated using the VIRCO recombinant virus assay. Genotypic sequencing was done on selected specimens from patients receiving zidovudine/nevirapine/didanosine. After 24 weeks, all available isolates taken from patients receiving nevirapine were resistant to this agent, while 18/21 (86%) patients receiving triple therapy carried such isolates at 30--60 weeks. At 24 weeks, zidovudine resistance developed in 4/40 isolates but was more frequent after 30--60 weeks, especially in patients on two drugs. The degree of zidovudine resistance (rise in concentration required for 50% inhibition) appeared lower in the triple therapy group compared with zidovudine/didanosine (P = 0.0004). All nevirapine-resistant isolates that were sequenced carried at least one mutation associated with resistance, most often K103N and/or Y181C. The use of highly active drug therapies may be associated with a beneficial effect on the development of antiretroviral drug resistance. The characteristics of virologic suppression that must be maintained to avoid resistance are currently being studied in hypothesis-driven clinical trials.

Swaziland has the highest adult HIV prevalence and second highest rate of TB/HIV coinfection globally. Recently, the Ministry of Health and partners have increased integration and co-location of TB/HIV services, but the timing of antiretroviral therapy (ART) relative to TB treatment-a marker of program quality and predictor of outcomes-is unknown. We conducted a retrospective analysis of programmatic data from 11 purposefully-sampled facilities to evaluate timely ART provision for HIV-positive TB patients enrolled on TB treatment between July-November 2014. Timely ART was defined as within two weeks of TB treatment initiation for patients with CD4<50/μL or missing, and within eight weeks otherwise. Descriptive statistics were estimated and logistic regression used to assess factors independently associated with timely ART. Of 466 HIV-positive TB patients, 51.5% were male, median age was 35 (interquartile range [IQR]: 29-42), and median CD4 was 137/μL (IQR: 58-268). 189 (40.6%) were on ART prior to, and five (1.8%) did not receive ART within six months of TB treatment initiation. Median time to ART after TB treatment initiation was 15 days (IQR: 14-28). Almost 90% started ART within eight weeks, and 45.5% of those with CD4<50/μL started within two weeks. Using thresholds for "timely ART" according to baseline CD4 count, 73.3% of patients overall received timely ART after TB treatment initiation. Patients with CD4 50-200/μL or ≥200/μL had significantly higher odds of timely ART than patients with CD4<50/μL, with adjusted odds ratios of 11.5 (95% confidence interval [CI]: 5.0-26.6) and 9.6 (95% CI: 4.6-19.9), respectively. TB cure or treatment completion was achieved by 71.1% of patients at six months, but this was not associated with timely ART. This study demonstrates the relative success of integrated and co-located TB/HIV services in Swaziland, and shows that timely ART uptake for HIV-positive TB patients can be achieved in resource-limited, but integrated

: Periimplantitis is a bacterial complication after dental implants implantation. Photodynamic therapy (PDT) implies the use of low-power laser in combination with appropriate photosensitizer to increase the detoxification of the implant surfaces. Little information exists about PDT in the treatment of periimplantitis. A randomized comparative case-control study has been conducted with 20 patients and 20 controls to compare the efficacy of antimicrobial PDT versus surgical therapy in patients with periimplantitis, who have received dental implants with rough surfaces. In the surgery group, mucoperiosteal flap surgery was used with scaling on implant surfaces and debridement of granulation tissue. Microbiologic testing was evaluated before and after intervention treatment, at 12 and 24 weeks in the study subjects. Total anaerobic counts of bacteria did not differ significantly between patients assigned to receive PDT and those assigned to receive surgical therapy (mean, 95.2% and 80.85%, respectively). PDT was associated with a significant decrease in bleeding scores (P = 0.02) as well as inflammatory exudation (P = 0.001). Treatment with PDT in patients with periimplantitis was not associated with major reduction of total anaerobic bacteria on the rough surfaces of dental implants as compared with surgical therapy. A significantly lower proinflammatory index of periimplantitis was observed in the PDT group at 24 weeks of follow-up.

The study aimed to identify factors associated with the survival of patients receiving antiretroviral therapy. A historic cohort of HIV patients from two major hospitals in Goma (Democratic Republic of Congo) was followed from 2004 to 2012. The Kaplan-Meier method was used to describe the probability of survival as a function of time since inclusion into the cohort. The log-rank test was used to compare survival curves based on determinants. The Cox regression model identified the determinants of survival since treatment induction. The median follow-up time was 3.56 years (IQR=2.22-5.39). The mortality rate was 40 deaths per 1000 person-years. Male gender (RR: 2.56; 95 %CI 1.66-4.83), advanced clinical stage (RR: 2.12; 95 %CI 1.15-3.90), low CD4 count (CD4 < 50) (RR: 2.05; 95 %CI : 1.22-3.45), anemia (RR: 3.95; 95 %CI 2.60-6.01), chemoprophylaxis with cotrimoxazole (RR: 4.29, 95 % CI 2.69-6.86) and period of treatment initiation (2010-2011) (RR: 3.34; 95 %CI 1.24-8.98) were statistically associated with short survival. Initiation of treatment at an early stage of the disease with use of less toxic molecules and an increased surveillance especially of male patients are recommended to reduce mortality.

Hemorrhagic transformation is an important complication of acute ischemic stroke, particularly in diabetic patients receiving thrombolytic treatment with tissue plasminogen activator, the only approved drug for the treatment of acute ischemic stroke. The objective of the present study was to determine the effects of acute manipulation of potential targets for vascular protection [i.e., NF-κB, peroxynitrite, and matrix metalloproteinases (MMPs)] on vascular injury and functional outcome in a diabetic model of cerebral ischemia. Ischemia was induced by middle cerebral artery occlusion in control and type 2 diabetic Goto-Kakizaki rats. Treatment groups received a single dose of the peroxynitrite decomposition catalyst 5,10,15,20-tetrakis(4-sulfonatophenyl)prophyrinato iron (III), the nonspecific NF-κB inhibitor curcumin, or the broad-spectrum MMP inhibitor minocycline at reperfusion. Poststroke infarct volume, edema, hemorrhage, neurological deficits, and MMP-9 activity were evaluated. All acute treatments reduced MMP-9 and hemorrhagic transformation in diabetic groups. In addition, acute curcumin and minocycline therapy reduced edema in these animals. Improved neurological function was observed in varying degrees with treatment, as indicated by beam-walk performance, modified Bederson scores, and grip strength; however, infarct size was similar to untreated diabetic animals. In control animals, all treatments reduced MMP-9 activity, yet bleeding was not improved. Neuroprotection was only conferred by curcumin and minocycline. Uncovering the underlying mechanisms contributing to the success of acute therapy in diabetes will advance tailored stroke therapies. PMID:23335797

Some studies suggest that combination antiretroviral therapy in pregnant women with human immunodeficiency virus type 1 (HIV-1) infection increases the risk of premature birth and other adverse outcomes of pregnancy. We studied pregnant women with HIV-1 infection who were enrolled in seven clinical studies and delivered their infants from 1990 through 1998. The cohort comprised 2123 women who received antiretroviral therapy during pregnancy (monotherapy in 1590, combination therapy without protease inhibitors in 396, and combination therapy with protease inhibitors in 137) and 1143 women who did not receive antiretroviral therapy. After standardization for the CD4+ cell count and use or nonuse of tobacco, alcohol, and illicit drugs, the rate of premature delivery (<37 weeks of gestation) was similar among the women who received antiretroviral therapy and those who did not (16 percent and 17 percent, respectively); the rate of low birth weight (<2500 g) was 16 percent among the infants born to both groups; and the rate of very low birth weight (<1500 g) was 2 percent for the group that received antiretroviral therapy and 1 percent for the group that did not. The rates of low Apgar scores (<7) and stillbirth were also similar or the same in the two groups. After adjustment for multiple risk factors, combination antiretroviral therapy was not associated with an increased risk of premature delivery as compared with monotherapy (odds ratio, 1.08; 95 percent confidence interval, 0.71 to 1.62) or delivery of an infant with low birth weight (odds ratio, 1.03; 95 percent confidence interval, 0.64 to 1.63). Seven of the women who received combination therapy with protease inhibitors (5 percent) had infants with very low birth weight, as compared with nine women who received combination therapy without protease inhibitors (2 percent) (adjusted odds ratio, 3.56; 95 percent confidence interval, 1.04 to 12.19).

Background: Distal radius fractures (DRFs) are one of the most common injuries among the elderly, resulting in significant expense and disability. The specific aims of this study are (1) to examine rates of therapy following DRFs and (2) to identify those factors that influence utilization of therapy and time span between DRF treatment and therapy among a national cohort of elderly patients. Methods: We examined national use of physical and occupational therapy among all Medicare beneficiaries who suffered DRFs between January 1, 2007, and October 1, 2007, and assessed the effect of treatment, patient-related, and surgeon-related factors on utilization of therapy. Results: Overall, 20.6% of patients received either physical or occupational therapy following DRF. Use of therapy varied by DRF treatment, and patients who underwent open reduction and internal fixation were more likely to receive therapy compared with patients who received closed reduction. Patients who received open reduction and internal fixation were also referred to therapy earlier compared with patients who received external fixation, percutaneous pinning, and closed reduction. Surgeon specialization is associated with greater use of postoperative therapy. Patient predictors of therapy use include younger age, female sex, higher socioeconomic status, and fewer comorbidity conditions. Conclusion: Use of therapy following DRF varies significantly by both patient- and surgeon-related factors. Identifying patients who benefit from postinjury therapy can allow for better resource utilization following these common injuries. PMID:25289323

To identify the role of therapeutic drug monitoring of itraconazole (ITZ) in the setting of empirical antifungal therapy with intravenous (IV) ITZ, we performed a multicenter, prospective study in patients with hematological malignancies who had received antifungal prophylaxis with ITZ oral solution (OS). We evaluated the plasma levels of ITZ and hydroxy (OH) ITZ both before initiation of IV ITZ and on days 5-7 of IV ITZ. A total of 181 patients showed an overall success rate of 68.0 %. Prolonged baseline neutropenia and accompanying cardiovascular comorbidity were significantly associated with poor outcomes of the empirical antifungal therapy (P = 0.005 and P = 0.001, respectively). A significantly higher trough plasma level of OH ITZ per body weight was found in the patients who achieved success with empirical antifungal therapy (P = 0.036). There were no significant correlations between plasma concentrations of ITZ/OH ITZ (baseline or trough levels) and toxicities. Seven patients had a discontinuation of ITZ therapy due to toxicity. This study demonstrated that IV ITZ as empirical antifungal therapy was effective and therapeutic drug monitoring was helpful to estimate the outcome of empirical antifungal therapy in patients receiving antifungal prophylaxis with ITZ OS. To predict the outcome of empirical antifungal therapy with IV ITZ, we should evaluate baseline clinical characteristics and also perform the therapeutic drug monitoring of both ITZ and OH ITZ.

Thrombolytic Treatment for Ischaemic Stroke: Could the Crisis of Confidence Have Been Avoided by Better Analysis of Trial Data?

PubMed

Barer, David; Berge, Eivind

2017-02-01

In many countries, thrombolysis with intravenous alteplase has become a central part of acute stroke care in recent years, requiring radical restructuring of services. However, a significant minority of emergency and stroke physicians have always had serious doubts about the safety and efficacy of thrombolytic treatment, and in 2015 these prompted a major review of the licensing status of alteplase by the UK regulatory authorities. Subsequent dramatic headlines and media stories have called into question the integrity of researchers and clinicians and undermined public faith in medical research. How did this situation arise and what should be done to prevent a repetition as we enter the era of intra-arterial treatment for stroke?Early intravenous alteplase increases the chances both of good recovery and of severe haemorrhage, so the risk/benefit balance must be assessed for individual patients according to stroke severity. For older patients and those with bigger strokes, the 'good recovery' criterion is an inefficient way of assessing treatment effects since few achieve full independence and differences between levels of functional impairment are ignored. This waste of information can be reduced by applying different criteria for 'good' and 'poor' outcomes in different prognostic groups (as clinicians do intuitively), hence increasing the number of patients contributing useful data. Such 'three-way prognosis-based outcome' analysis of existing and future trials could greatly increase the amount of relevant evidence to guide clinical decisions for individual patients across the range of stroke severity.

Recurrent hemorrhage from corpus luteum during anticoagulant therapy.

Wong, K. P.; Gillett, P. G.

1977-01-01

A 43-year old woman had recurrent massive intraperitoneal hemorrhage from rupture of a hemorrhagic corpus luteum in two successive menstrual cycles while receiving anticoagulant therapy. Left oophorectomy was performed on the first occasion and right salpingo-oophorectomy with left salpingectomy on the second. While the precise incidence cannot be determined, rupture from a hemorrhagic corpus luteum appears to be a rare but potentially catastrophic complication of anticoagulant therapy. Hence possible ovarian hemorrhage should be considered in women of reproductive age receiving heparin or sodium warfarin therapy. PMID:844024

Identifying characteristics of HIV-infected adults likely to have poor treatment outcomes can be useful for targeting interventions efficiently. Research in economics and psychology suggests that individuals' intertemporal time preferences, which indicate the extent to which they trade-off immediate vs. future cost and benefits, can influence various health behaviors. While there is empirical support for the association between time preferences and various non-HIV health behaviors and outcomes, the extent to which time preferences predict outcomes of those receiving antiretroviral therapy (ART) has not been examined previously. HIV-infected adults initiating ART were enrolled at a health facility in Kenya. Participants' time preferences were measured at enrollment and used to classify them as having either a low or high discount rate for future benefits. At 48 weeks, we assessed mortality and ART adherence, as measured by Medication Event Monitoring System (MEMS). Logistic regression models adjusting for socio-economic characteristics and risk factors were used to determine the association between time preferences and mortality as well as MEMS adherence ≥90%. Overall, 44% (96/220) of participants were classified as having high discount rates. Participants with high discount rates had significantly higher 48-week mortality than participants with low discount rates (9.3% vs. 3.1%; adjusted odds ratio 3.84; 95% CI 1.03, 14.50). MEMS adherence ≥90% was similar for participants with high vs. low discount rates (42.3% vs. 49.6%, AOR 0.70; 95% CI 0.40, 1.25). High discount rates were associated with significantly higher risk of mortality among HIV-infected patients initiating ART. Greater use of time preference measures may improve identification of patients at risk of poor clinical outcomes. More research is needed to further identify mechanisms of action and also to build upon and test the generalizability of this finding.

The overall objective of the Polish guidelines for the prevention and treatment of venous thromboembolism is to increase patient benefit and safety by appropriate prevention and treatment of deep vein thrombosis and pulmonary embolism as well as proper management of the complications associated with antithrombotic and thrombolytic therapy. These guidelines apply to adult trauma, cancer, surgical, and medical patients as well as those at increased risk of venous thromboembolism. Specific recommendations have been formulated for pregnant women, patients requiring surgery while receiving long-term oral anticoagulant treatment, and patients undergoing regional anesthesia and/or analgesia. We chose to update the existing Polish guidelines with the use of the most recent high-quality international guidelines that we identified and adjusted the final product to Polish cultural and organizational setting. We based our recommendations primarily on the 9th edition of the American College of Chest Physicians Evidence-Based Clinical Practice Guidelines on Antithrombotic Therapy and Prevention of Thrombosis, the European Society of Cardiology Guidelines on the Diagnosis and Management of Acute Pulmonary Embolism, the 3rd edition of the American Society of Regional Anesthesia and Pain Medicine Evidence-Based Guidelines on Regional Anesthesia in the Patient Receiving Antithrombotic or Thrombolytic Therapy, the ACOG practice bulletin on thromboembolism in pregnancy (Number 123), and Guidance from the Scientific and Standardisation Committee of the International Society on Thrombosis and Haemostasis on the Duration of Anticoagulant Therapy after a First Episode of Unprovoked Pulmonary Embolus or Deep Vein Thrombosis, as well as two other Polish practice guidelines on the prophylaxis and treatment of venous thromboembolism and the management of patients treated with oral direct inhibitors of factor X or factor II.

On the basis of phase II trials, we considered that transcranial laser therapy could have neuroprotective effects in patients with acute ischemic stroke. We studied transcranial laser therapy in a double-blind, sham-controlled randomized clinical trial intended to enroll 1000 patients with acute ischemic stroke treated ≤24 hours after stroke onset and who did not undergo thrombolytic therapy. The primary efficacy measure was the 90-day functional outcome as assessed by the modified Rankin Scale, with hierarchical Bayesian analysis incorporating relevant previous data. Interim analyses were planned after 300 and 600 patients included. The study was terminated on recommendation by the Data Monitoring Committee after a futility analysis of 566 completed patients found no difference in the primary end point (transcranial laser therapy 140/282 [49.6%] versus sham 140/284 [49.3%] for good functional outcome; modified Rankin Scale, 0-2). The results remained stable after inclusion of all 630 randomized patients (adjusted odds ratio, 1.024; 95% confidence interval, 0.705-1.488). Once the results of the interim futility analysis became available, all study support was immediately withdrawn by the capital firms behind PhotoThera, and the company was dissolved. Proper termination of the trial was difficult but was finally achieved through special efforts by former employees of PhotoThera, the CRO Parexel and members of the steering and the safety committees. We conclude that transcranial laser therapy does not have a measurable neuroprotective effect in patients with acute ischemic stroke when applied within 24 hours after stroke onset. http://www.clinicaltrials.gov.

Spontaneous or traumatic bleeding is a common complication of systemic thrombolysis in patients with acute ischemic stroke. We report the case of an 83 y.o. woman with right facio-brachio-crural hemiparesis, left deviation of the head and aphasia who developed, after thrombolytic therapy, a spontaneous sternocleidomastoid muscle hematoma that regressed few days later. To our knowledge, this is the first case reported in the literature of asymptomatic and spontaneous skeletal muscle hematoma following thrombolysis for the treatment of acute ischemic stroke. The occurrence of lateral cervical tuberculosis lymphadenitis ipsilateral to sternocleidomastoid muscle hematoma may suggest a causal relationship between local chronic inflammation of active mycobacterial infection and thrombolysis-related extravasation. This case should suggest caution in thrombolytic treatment in patients with chronic immune dysregulation and vascular inflammation such as extra-pulmonary tuberculosis. Copyright © 2014 Elsevier B.V.

Patients with Chronic Lymphocytic Leukemia (CLL) are known to have an increased incidence of second cancers, but the contribution of commonly used frontline therapies to the incidence of second cancers is unclear. We report on the characteristics, incidence, outcomes and factors associated with second cancers in 234 patients receiving Fludarabine, Cyclophosphamide, and Rituximab (FCR) based regimens in the frontline setting. The risk of second cancers was 2.38 times higher than the expected risk in the general population. Ninety three patients (40%) had other cancers before and 66 patients (28%) after FCR. The rates of t-AML/MDS (5.1%) and Richter’s transformation (RT) (9%) were high while solid tumors were not increased. Overall survival of patients with second cancers after frontline FCR was shorter (median of 4.5 years) compared to patients with and without prior cancers. Second cancer risk after frontline FCR is mainly due to high rates of t-AML/MDS and RT and as speculated the survival of affected patients is shorter. PMID:25308294

Background The combined use of aspirin and oral anticoagulant therapy in patients with atrial fibrillation (AF) and stable coronary artery disease (CAD) has been questioned due to an increased risk of major bleeding with little to no benefit in preventing ischemic events. Objective (1) To better understand patterns and indications for combined antiplatelet and anticoagulant therapy and identify patients who might reasonably be treated with oral anticoagulant (OAC) therapy alone. (2) To perform an updated literature review regarding the use of combined antiplatelet and OAC therapy in patients with AF and stable CAD. Design and Participants Retrospective review. Patients within the University of Cincinnati Health System with a diagnosis of non-valvular AF, excluding those with acute coronary syndrome or revascularization within the last 12 months. Main Measures Numbers and indications for combined antiplatelet and anticoagulant therapy and sequence of events leading to the initiation of each. Key Results Of 948 patients receiving OAC, 430 (45%) were receiving concomitant OAC and aspirin. Among patients receiving combined antiplatelet and anticoagulant therapy, 49% and 42% of patients respectively, had CAD or DM. In a more detailed analysis including chart review of 219 patients receiving combined OAC and aspirin, 27% had a diagnosis of CAD and 14% had a diagnosis of DM prior to the development of AF. These patients were initially treated with aspirin. Warfarin was added when they subsequently developed AF but aspirin wasn’t discontinued. A surprisingly large proportion of patients (22.8%) had no obvious indication for dual therapy. Conclusions Prior myocardial infarction, CAD, vascular disease and DM (among others) increase the likelihood of receiving combined antiplatelet and anticoagulant therapy among patients with AF. A literature review suggests this may lead to increased major bleeding with little benefit in decreasing either AF-related stroke or

Anxiety is common among breast-cancer survivors. This analysis examined the effect of a hypnotic relaxation therapy, developed to reduce hot flashes, on anxiety levels of female breast-cancer survivors. Anxiety was assessed using a numeric analog scale and the Hospital Anxiety and Depression Scale-Anxiety subscale. Significant reductions in anxiety were found from pre- to postintervention for each weekly session and were predictive of overall reductions in anxiety from baseline to after the last intervention. In this analysis, hypnotizability did not significantly predict for anxiety reductions measured before and after each session or from baseline to exit. These data provide initial support for the use of hypnotic relaxation therapy to reduce anxiety among breast-cancer survivors. PMID:27585723

We report the first randomized prospective comparative study of long-term maintenance ganciclovir (9-[2-hydroxy-1-(hydroxymethyl)ethoxymethyl]guanine, BW759U, DHPG) therapy for cytomegalovirus retinitis in patients with the acquired immunodeficiency syndrome (AIDS). Eleven retinitis patients who received a 10-day course of ganciclovir induction therapy and then were randomized to receive either immediate daily ganciclovir maintenance therapy or deferred maintenance (eight deferred maintenance, three immediate maintenance) were evaluated for drug efficacy. Median time to retinitis progression was 42 days for the immediate maintenance group compared with 16 days for the deferred maintenance group, (P = 0.07). After crossing over to maintenance therapy, patients in the deferred group had a median time to retinitis progression of 58 days compared to 16 days while not on maintenance therapy (P = 0.13). Only 9% of cultures obtained while patients received maintenance therapy were positive for cytomegalovirus, vs 40% of those obtained off maintenance (P less than 0.001). We can state then that maintenance therapy with ganciclovir delays, but does not halt, progression of cytomegalovirus retinitis and suppresses, but does not eradicate, cytomegalovirus shedding in patients with AIDS.

To test a tool-kit designed to improve well-being in patients with prostate cancer. Lifestyle changes might lessen the metabolic, cardiovascular, and osseous side effects of androgen deprivation therapy (ADT) in prostate cancer patients. Urologists supplied 10 consecutive patients initiating ADT with a tool-kit (information brochure, practical guidance on diet and exercise, recipe booklet, and lifestyle diary). The urologists completed a total 4 questionnaires, at study initiation, one at the patients' first and second visits, and one at study completion. Overall, 91 urologists completed all questionnaires; 585 patients (median age, 75 years) were seen at the first visit, and 511 patients at the second. Patient response rate to the first questionnaire was 62% and 56% to the second. After the first visit, 82% of respondents reported being very glad or glad to receive the kit; among those having read the practical guidance (301/362), 57% had started implementation and 36% intended to do so. After the second visit, 76% were satisfied with the tool-kit and 84% were implementing guidance. Clinician satisfaction rate was 82%: benefits were improved patient dialogue (62%), follow-up (55%), and better explanation of side effects (51%). Only 14 clinicians were not pleased by the tool kit. Their main criticisms (too long, tedious, not tailored to individual needs) matched those of patients. Written detailed guidance on diet and physical exercise for patients about to receive ADT met a genuine need and was well perceived by both clinicians and patients. Implementation rate was high. However, content should be adapted to patient age and disease stage. Copyright © 2010 Elsevier Inc. All rights reserved.

Tofacitinib, an oral, small-molecule Janus kinase inhibitor, was shown to have potential efficacy as induction therapy for ulcerative colitis in a phase 2 trial. We further evaluated the efficacy of tofacitinib as induction and maintenance therapy. We conducted three phase 3, randomized, double-blind, placebo-controlled trials of tofacitinib therapy in adults with ulcerative colitis. In the OCTAVE Induction 1 and 2 trials, 598 and 541 patients, respectively, who had moderately to severely active ulcerative colitis despite previous conventional therapy or therapy with a tumor necrosis factor antagonist were randomly assigned to receive induction therapy with tofacitinib (10 mg twice daily) or placebo for 8 weeks. The primary end point was remission at 8 weeks. In the OCTAVE Sustain trial, 593 patients who had a clinical response to induction therapy were randomly assigned to receive maintenance therapy with tofacitinib (either 5 mg or 10 mg twice daily) or placebo for 52 weeks. The primary end point was remission at 52 weeks. In the OCTAVE Induction 1 trial, remission at 8 weeks occurred in 18.5% of the patients in the tofacitinib group versus 8.2% in the placebo group (P=0.007); in the OCTAVE Induction 2 trial, remission occurred in 16.6% versus 3.6% (P<0.001). In the OCTAVE Sustain trial, remission at 52 weeks occurred in 34.3% of the patients in the 5-mg tofacitinib group and 40.6% in the 10-mg tofacitinib group versus 11.1% in the placebo group (P<0.001 for both comparisons with placebo). In the OCTAVE Induction 1 and 2 trials, the rates of overall infection and serious infection were higher with tofacitinib than with placebo. In the OCTAVE Sustain trial, the rate of serious infection was similar across the three treatment groups, and the rates of overall infection and herpes zoster infection were higher with tofacitinib than with placebo. Across all three trials, adjudicated nonmelanoma skin cancer occurred in five patients who received tofacitinib and in one

Effects of lipoprotein(a) on thrombolysis.

Lipoprotein(a) (Lp(a)) and plasminogen share a high degree of structural homology. Therefore it has been suggested that elevated levels of Lp(a) may inhibit the profibrinolytic activity at the cell surface and increase the risk of thrombosis by competitive inhibition of plasminogen. In the present study we evaluated whether high levels of Lp(a) affect thrombolytic therapy in patients with acute myocardial infarction. Forty-one patients with acute myocardial infarction were treated with a combination of recombinant tissue-type plasminogen activator and human single-chain urokinase-type plasminogen activator. Coronary patency was assessed angiographically 90 min after initiation of treatment. Thrombolysis was successful in 30 and unsuccessful in 11 patients. Patients with high Lp(a) levels (> 25 mg/dl) (n = 9) responded equally well to thrombolytic therapy (8 of 9, patency 89%) as did patients with normal or low levels of Lp(a) (22 of 32, patency 70%, difference P > 0.1). The results demonstrate that high levels of Lp(a) do not influence thrombolysis in patients with acute myocardial infarction when low-dose pharmacologic concentrations of recombinant tissue-type plasminogen activator and human single chain urokinase-type plasminogen activator are applied in combination.
