    Full Text Available Introduction Electroconvulsive therapy (ECT is considered the most effective treatment for catatonia regardless its underlying condition. The rigid fixed posture and immobility observed in catatonia may lead to several clinical complications, of which, pulmonary embolism (PE is one of the most severe. The rapid improvement of the psychiatric condition in catatonia-related PE is essential, since immobility favors the occurrence of new thromboembolic events and further complications. In that scenario, ECT should be considered, based on a risk-benefit analysis, aiming at the faster resolution of the catatonia. Methods Case report and literature review. Results A 66-years-old woman admitted to the psychiatric ward with catatonia due to a depressive episode presented bilateral PE. Clinically stable, but still severely depressed after a trial of antidepressants, she was treated with ECT in the course of full anticoagulation with enoxaparin. After five ECT sessions, her mood was significantly better and she was walking and eating spontaneously. She did not present complications related either to PE or to anticoagulation. After the eighth ECT session, she evolved with hypomania, which was managed with oral medication adjustments. The patient was completely euthymic at discharge. Conclusion The case we presented provides further evidence to the anecdotal case reports on the safety of ECT in the course of concomitant full anticoagulant therapy after PE, and illustrates how, with the proper precautions, the benefits of ECT in such condition might outweigh its risks.

    Full Text Available Abstract Introduction Spontaneous retroperitoneal hemorrhage is a distinct clinical entity that can present as a rare life-threatening event characterized by sudden onset of bleeding into the retroperitoneal space, occurring in association with bleeding disorders, intratumoral bleeding, or ruptures of any retroperitoneal organ or aneurysm. The spontaneous form is the most infrequent retroperitoneal hemorrhage, causing significant morbidity and representing a diagnostic challenge. Case presentation We report the case of a patient with coronary artery disease who presented with transient ischemic attack, in whom anticoagulant therapy with heparin precipitated a massive spontaneous atraumatic retroperitoneal hemorrhage (with international normalized ratio 2.4, which was treated conservatively. Conclusion Delay in diagnosis is potentially fatal and high clinical suspicion remains crucial. Finally, it is a matter of controversy whether retroperitoneal hematomas should be surgically evacuated or conservatively treated and the final decision should be made after taking into consideration patient's general condition and the possibility of permanent femoral or sciatic neuropathy due to compression syndrome.

    Background: High-quality anticoagulation management is required to keep these narrow therapeutic index medications as effective and safe as possible. This article focuses on the common important management questions for which, at a minimum, low-quality published evidence is available to guide best practices. Methods: The methods of this guideline follow those described in Methodology for the Development of Antithrombotic Therapy and Prevention of Thrombosis Guidelines: Antithrombotic Therapy and Prevention of Thrombosis, 9th ed: American College of Chest Physicians Evidence-Based Clinical Practice Guidelines in this supplement. Results: Most practical clinical questions regarding the management of anticoagulation, both oral and parenteral, have not been adequately addressed by randomized trials. We found sufficient evidence for summaries of recommendations for 23 questions, of which only two are strong rather than weak recommendations. Strong recommendations include targeting an international normalized ratio of 2.0 to 3.0 for patients on vitamin K antagonist therapy (Grade 1B) and not routinely using pharmacogenetic testing for guiding doses of vitamin K antagonist (Grade 1B). Weak recommendations deal with such issues as loading doses, initiation overlap, monitoring frequency, vitamin K supplementation, patient self-management, weight and renal function adjustment of doses, dosing decision support, drug interactions to avoid, and prevention and management of bleeding complications. We also address anticoagulation management services and intensive patient education. Conclusions: We offer guidance for many common anticoagulation-related management problems. Most anticoagulation management questions have not been adequately studied. PMID:22315259

    During extracorporeal dialysis, some anticoagulation strategy is necessary to prevent the coagulation of blood. Heparin has historically been used as an anticoagulant because of its efficacy combined with low cost. However, a variable incidence of hemorrhagic complications (5-30%) has been documented in patients undergoing continuous renal replacement therapy (CRRT) with heparin as an anticoagulant. Citrate has anticoagulation properties secondary to its ability to chelate calcium, which is necessary for the coagulation cascade. Citrate may thus be used in a regional anticoagulation (RCA), limited to the extracorporeal circuit of CRRT, to avoid systemic anticoagulation. Recent meta-analysis confirmed the advantage of RCA over heparin in terms of incidence of bleeding during CRRT. Moreover, an increase in filter lifespan is documented, with a secondary advantage in reaching the prescribed dialysis dose. In our experience, we could confirm this positive effect. In fact, with a progressive increase in the proportion of CRRT with citrate as RCA, we obtained a reduction in the number of filters used for every 72 h of treatment (from 2.4 in 2011 to 1.3 in 2015), and most importantly, a reduction in the difference between the prescribed and delivered dialysis doses (from 22 to 7%). Citrate has an intense effect on the acid-base balance as well, if fully metabolized through the Krebs cycle, due to the production of bicarbonate. Even more severely ill patients, such as those with liver dysfunction, may be treated with RCA without severe complications, because modern machines for CRRT are equipped with simple systems that are able to manage the citrate infusion and control the calcium levels, with minimal risks of metabolic derangements. © 2017 S.

    Full Text Available Introduction: Liver transplant recipients are at risk for complications of vascular thrombosis. The reconstructed hepatic artery and portal vein thrombosis potentially result in hepatic failure and graft loss. Renal infarction is a rare clinical condition, but in severe cases, it may lead to renal failure. We herein report a case of renal infarction after living donor liver transplantation (LDLT during anticoagulant therapy. Case Presentation: A 60-year-old woman with end-stage liver disease due to primary biliary cholangitis underwent LDLT with splenectomy. Postoperatively, tacrolimus, mycophenolate mofetil, and steroid were used for initial immunosuppression therapy. On postoperative day (POD 5, enhanced computed tomography (CT revealed splenic vein thrombosis, and anticoagulant therapy with heparin followed by warfarin was given. Follow-up enhanced CT on POD 20 incidentally demonstrated right renal infarction. The patient’s renal function was unchanged and the arterial flow was good, and the splenic vein thrombosis resolved. At 4 months postoperatively, warfarin was discontinued, but she developed recurrent splenic vein thrombosis 11 months later, and warfarin was resumed. As of 40 months after transplantation, she discontinued warfarin and remains well without recurrence of splenic vein thrombosis or renal infarction. Conclusion: Renal infarction is a rare complication of LDLT. In this case, renal infarction was incidentally diagnosed during anticoagulant therapy and was successfully treated.

    CT were performed in thirteen patients (12 women, 1 man) aged from 53 to 90 (mean age, 74) with severe RSH. Five patients also underwent ultrasound examination and three MR examination. Nine patients (69%) were receiving subcutaneous injection of heparin, three (23%) oral anticoagulant therapy and one continuous IV infusion of heparin. Clinical diagnosis was reached in 6 cases. Excessive activity of anticoagulant therapy was noted in 4 cases. The location of the RSH, their densities and their signals were analysed. All the RSH were mostly developed in the lower third of the abdominal wall, had a large spreading into the Retzius space and compressed the bladder and/or the bowels. RSH were all hyperdense and in 8 cases (61%) a fluid-fluid level due to the hematocrit effect was noted. In one case, a retroperitoneal hematoma was discovered. The extension of the RSH was well delineated with MRI. The RSH showed itself with heterogeneous signal intensities with areas of high-signal-intensity on T1-weighted images. Fluid-fluid levels and a concentric ring sign were also noted. Older women with subcutaneous injection of heparin are especially prone to RSH even though there is no overall excessive activity of anticoagulant therapy. Clinical and biological diagnosis may be difficult. CT scan is the exam of choice to reach a precise and acute diagnosis of RSH. (authors). 34 refs., 8 figs

  11. The mythology of anticoagulation therapy interruption for dental surgery.

    Science.gov (United States)

    Wahl, Michael J

    2018-01-01

    Continuous anticoagulation therapy is used to prevent heart attacks, strokes, and other embolic complications. When patients receiving anticoagulation therapy undergo dental surgery, a decision must be made about whether to continue anticoagulation therapy and risk bleeding complications or briefly interrupt anticoagulation therapy and increase the risk of developing embolic complications. Results from decades of studies of thousands of dental patients receiving anticoagulation therapy reveal that bleeding complications requiring more than local measures for hemostasis have been rare and never fatal. However, embolic complications (some of which were fatal and others possibly permanently debilitating) sometimes have occurred in patients whose anticoagulation therapy was interrupted for dental procedures. Although there is now virtually universal consensus among national medical and dental groups and other experts that anticoagulation therapy should not be interrupted for most dental surgery, there are still some arguments made supporting anticoagulation therapy interruption. An analysis of these arguments shows them to be based on a collection of myths and half-truths rather than on logical scientific conclusions. The time has come to stop anticoagulation therapy interruption for dental procedures. Copyright © 2018 American Dental Association. Published by Elsevier Inc. All rights reserved.

    Taiji Kuwata

    Full Text Available Introduction: Postoperative pulmonary embolism (PE is the one of the most important complications after thoracic surgery. This complicatin after the surgery is often treated by new anticoaglant drug, such as rivaroxaban, which dose not need to the monitoring of blood coaglation system. We experienced postoperative bleeding case during anticoaglant therapy using rivaroxaban. Presentation of case: The patient underwent a right upper lobectomy with lung and chest wall resection for lung cancer. On postoperative day (POD 10, we started to use rivaroxaban to treat the deep vein thrombosis (DVT. Four days after starting the rivaroxaban treatment, severe surgical site hemorrhage occurred, which led to the need for the infusion of concentrated red cells (CRC. After stopping the rivaroxaban, the thoracic bleeding ceased. Because the event occurred so long after the surgery, and because the bleeding stopped after withdrawal of treatment, we believe that rivaroxaban induced the thoracic bleeding. Conclusion: Some reports in the field of orthopedics (Turpie et al., 2009 have noted that rivarxaban is effective to prevent postoperative DVT. However, there were few reports that invied the attention to postoperative bleeding be induced by rivarxaban. Thus, we describe this case in order to alert clinicians to the potential bleeding risks associated with the admistration of rivaroxaban postoperatively.

    Full Text Available Introduction and Objective: Spontaneous pharyngeal-laryngeal hematoma shows the importance of a complete ENT examination in the face of symptoms of banal appearance and a correct history that, in the case reported, unveiled the therapeutic use of anticoagulants. Case description: A 55 year old woman comes to emergency because of unexplained dysphagia. The inspection shows the presence of a hematoma in the pharyngeal-laryngeal region that, after the anticoagulant therapy was reversed, evolved favorably with conservative treatment. Discussion: In this case, apart from medical management performed by the hematology department, we focus our therapeutic approach in the protection of the airway and the prevention of a possible massive bleeding. Determining which patients require endotracheal intubation or tracheostomy and hemostatic surgery is the key to treatment. Conclusions: The anticoagulant therapy involves several complications that ENT specialists must consider in the face of clinical symptoms of dysphagia, dysphonia, dyspnea or signs of bleeding and they must know the possibilities of performance depending on the severity of each case.

  15. A Case of Acute Budd-Chiari Syndrome Complicating Primary Antiphospholipid Syndrome Presenting as Acute Abdomen and Responding to Tight Anticoagulant Therapy

    Full Text Available A 34-year-old woman with primary antiphospholipid syndrome was admitted to the Gastroenterology Department of our hospital with fever, acute abdomen, watery diarrhea, and extremely high levels of inflammatory parameters. She had a history of left lower limb deep vein thrombosis and pulmonary embolism and was taking warfarin potassium. Acute gastroenteritis was suspected and an antibiotic was administered, but symptoms progressed. Abdominal ultrasonography showed occlusion of the left hepatic vein and the middle hepatic vein and her D-dimer level was high. Accordingly, Budd-Chiari syndrome was diagnosed and high-dose intravenous infusion of heparin was initiated. Her abdominal symptoms improved and the levels of inflammatory parameters and D-dimer decreased rapidly. It is known that antiphospholipid syndrome can be complicated by Budd-Chiari syndrome that usually occurs as subacute or chronic onset, but acute onset is rare. It is difficult to diagnose acute Budd-Chiari syndrome complicating antiphospholipid syndrome and this complication generally has a poor outcome. However, the present case can get early diagnosis and successful treatment with tight anticoagulant therapy.

    Full Text Available Background. Oral anticoagulants have been used in the prevention of thromboembolic complications for over six decades. A rare, but possible problem in the application of these medications could be resistance to them. Case report. We presented a patient with nonocclusive thrombosis of the mechanical mitral prosthesis due to inadequately treated resistance to peroral anticoagulant therapy. Resistance to oral anticoagulant medications was proven by an increased dosage of warfarin up to 20 mg and, after that, acenokumarol to 15 mg over ten days which did not lead to an increase in the international normalized ratio (INR value over 1.2. On the basis of information that she did not take food rich in vitamin K or medications which could reduce effects of oral anticoagulants, and that she did not have additional illnesses and conditions that could cause an inadequate response to anticoagulant therapy, it was circumstantially concluded that this was a hereditary form of resistance. Because of the existing mechanical prosthetics on the mitral position, low molecular heparin has been introduced into the therapy. The patient reduced it on her own initiative, leading to nonocclusive valvular thrombosis. Conclusion. When associated complications like absolute arrhithmia does not exist, the finding of resistance to oral anticoagulant agents is an indication for the replacement of a mechanical prosthetic with a biological one which has been done in this patients.

    Full Text Available A 41-year-old woman, who underwent breast resection for cancer of the right breast and adjuvant chemotherapy 2 years ago, was admitted to our hospital due to shortness of breath upon exertion. High-resolution computed tomography of the chest showed small nodular opacities in the peribronchiolar area in both lungs, as well as mediastinal and hilar lymphadenopathy. A transbronchial lung biopsy revealed breast cancer metastasis and pulmonary tumor thrombotic microangiopathy (PTTM. Treatment of PTTM is rarely reported due to the difficulty of antemortem diagnosis; however, the patient was effectively treated with chemotherapy and oxygen and anticoagulation therapies for 3 months.

    Essentials Correct duration of treatment after a first unprovoked venous thromboembolism (VTE) is unknown. We assessed when restarting anticoagulation was worthwhile based on patient risk of recurrent VTE. When the risk over a one-year period is 17.5%, restarting is cost-effective. However, sensitivity analyses indicate large uncertainty in the estimates. Background Following at least 3 months of anticoagulation therapy after a first unprovoked venous thromboembolism (VTE), there is uncertainty about the duration of therapy. Further anticoagulation therapy reduces the risk of having a potentially fatal recurrent VTE but at the expense of a higher risk of bleeding, which can also be fatal. Objective An economic evaluation sought to estimate the long-term cost-effectiveness of using a decision rule for restarting anticoagulation therapy vs. no extension of therapy in patients based on their risk of a further unprovoked VTE. Methods A Markov patient-level simulation model was developed, which adopted a lifetime time horizon with monthly time cycles and was from a UK National Health Service (NHS)/Personal Social Services (PSS) perspective. Results Base-case model results suggest that treating patients with a predicted 1 year VTE risk of 17.5% or higher may be cost-effective if decision makers are willing to pay up to £20 000 per quality adjusted life year (QALY) gained. However, probabilistic sensitivity analysis shows that the model was highly sensitive to overall parameter uncertainty and caution is warranted in selecting the optimal decision rule on cost-effectiveness grounds. Univariate sensitivity analyses indicate variables such as anticoagulation therapy disutility and mortality risks were very influential in driving model results. Conclusion This represents the first economic model to consider the use of a decision rule for restarting therapy for unprovoked VTE patients. Better data are required to predict long-term bleeding risks during therapy in this

Vitamin K antagonists (VKA have been the standard of care for long-term OAT for decades, but non-VKA oral anticoagulants (NOAC have recently been approved for this indication, and raised many questions, among them their influence on medication adherence. We assessed adherence to VKA and NOAC in secondary stroke prevention. Methods: All patients treated from October 2011 to September 2012 for ischemic stroke or transient ischemic attack with a subsequent indication for OAT, at three academic hospitals were entered into a prospective registry, and baseline data and antithrombotic treatment at discharge were recorded. At the 1-year follow-up, we assessed the adherence to different OAT strategies and patients’ adherence to their respective OAT. We noted OAT changes, reasons to change treatment, and factors that influence persistence to the prescribed OAT. Results: In patients discharged on OAT, we achieved a fatality corrected response rate of 73.3% (n=209. A total of 92% of these patients received OAT at the 1-year follow-up. We observed good adherence to both VKA and NOAC (VKA, 80.9%; NOAC, 74.8%; P=0.243 with a statistically nonsignificant tendency toward a weaker adherence to dabigatran. Disability at 1-year follow-up was an independent predictor of lower adherence to any OAT after multivariate analysis, whereas the choice of OAT did not have a relevant influence. Conclusion: One-year adherence to OAT after stroke is strong (>90% and patients

    Until lately warfarin was the only valuable oral anticoagulant in stroke reduction in high risk cases with non valvular atrial fibrillation (NVAF). Although with warfarin the rate of stroke reduced notably, the major concern is the risk of serious bleeding and difficulty of establishing and maintaining the international normalised ratio (INR) within the therapeutic range. With the development of the novel anticoagulants we now have for the first time since the innovation of Warfarin feasible alternatives to it to decrease stroke rates in high risk patients with NVAF. To diminish adverse bleeding events with the novel anticoagulant proper selection of patients prior starting treatment is essential. Crown Copyright © 2013. Published by Elsevier B.V.

    Anticoagulant therapy is prescribed for millions of patients worldwide for the prevention and treatment of both arterial and venous thrombosis. Historically, only vitamin K antagonists have been available for clinicians to prescribe. The anticoagulation landscape is changing. The recent availability of the novel oral anticoagulants overcome many of the disadvantages associated with vitamin K antagonists. However the lack of formal monitoring and clinic follow-up is a concern for clinicians, as medication adherence is being assumed, which is known to decline in patients prescribed medications for chronic conditions. The switching study is a programme of work investigating the association between medication adherence and patient's beliefs about anticoagulation therapy (warfarin and subsequently novel oral anticoagulants), together with beliefs about their illness and anticoagulation related quality of life. The anticoagulation database at King's College Hospital will be interrogated and two groups of patients will be identified; those with a time in therapeutic range on warfarin of ≥75 % and those beliefs about medications compared. Those patients in the time in therapeutic range beliefs about medications, re-evaluated on the novel agent. The results from these sub-studies, will inform a clinical pathway to support patients on these novel agents, which will be evaluated in an independent group of patients. The results from the switching study will be used to develop a clinical pathway to support patient's prescribed novel oral anticoagulant therapy long-term.

    To evaluate the changes in transvalvular gradients and the incidence of valve haemodynamic deterioration (VHD) following transcatheter aortic valve replacement (TAVR), according to use of anticoagulation therapy. This multicentre study included 2466 patients (46% men; mean age 81±7 years) who underwent TAVR with echocardiography performed at 12-month follow-up. Anticoagulation therapy was used in 707 patients (28.7%) following TAVR (AC group). A total of 663 patients received vitamin K antagonists, and 44 patients received direct oral anticoagulants. A propensity score matching analysis was performed to adjust for intergroup (AC vs non-AC post-TAVR) differences. A total of 622 patients per group were included in the propensity-matched analysis. VHD was defined as a ≥10 mm Hg increase in the mean transprosthetic gradient at follow-up (vs hospital discharge). The mean clinical follow-up was 29±18 months. The mean transvalvular gradient significantly increased at follow-up in the non-AC group within the global cohort (P=0.003), whereas it remained stable over time in the AC group (P=0.323). The incidence of VHD was significantly lower in the AC group (0.6%) compared with the non-AC group (3.7%, P<0.001), and these significant differences remained within the propensity-matched populations (0.6% vs 3.9% in the AC and non-AC groups, respectively, P<0.001). The occurrence of VHD did not associate with an increased risk of all-cause death (P=0.468), cardiovascular death (P=0.539) or stroke (P=0.170) at follow-up. The lack of anticoagulation therapy post-TAVR was associated with significant increments in transvalvular gradients and a greater risk of VHD. VHD was subclinical in most cases and did not associate with major adverse clinical events. Future randomised trials are needed to determine if systematic anticoagulation therapy post-TAVR would reduce the incidence of VHD. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article

  6. OPTIONS FOR USE OF APPROPRIATE ANTICOAGULANT THERAPY IN PATIENTS WITH THERMAL INJURY WITH A HIGH RISK OF THROMBOEMBOLIC COMPLICATIONS DEVELOPMENT ASSOCIATED WITH RECURRENT INTESTINAL BLEEDING

    Full Text Available ABSTRACT. Patients with major thermal injury require anticoagulant therapy during almost the whole period of the burn disease, forcing the physician to balance constantly between the risk of possible bleeding associated with surgical treatment and the risk of thrombosis development in patients demonstrating a number of factors predisposing to the development of VTС. We report a clinical case of appropriate anticoagulant therapy using the new oral anticoagulants in a patient with a high risk of VTС development and recurrent bleeding from the tumor of the ascending colon.

    Full Text Available Bleeding represents the most feared complication of the new oral anticoagulants, direct oral anticoagulants (DOACs, as well as all the antithrombotic therapies. During the acute phase of bleeding in patients taking anticoagulants, restoration of an effective hemostasis represents the cornerstone of practical management. While vitamin K antagonists are effectively and promptly reversed by specific antidotes such as prothrombin complex concentrates (PCCs, fresh frozen plasma or vitamin K, it is still not clear how to manage the urgent reversal of DOACs during life-threatening or major bleedings due to the lack of specific antidotes. However, in vitro and ex vivo studies have suggested some potential strategies to reverse DOACs in clinical practice, other than general support measures that are always recommended. Activated charcoal could be used in subjects with DOAC-related bleedings presenting to the emergency department within two hours of the last oral intake. Non-activated or activated PCCs (FEIBA and recombinant activated Factor VII (raFVII seem to be the optimal strategy for urgent reversal of dabigatran, while non-activated PCCs seem to have efficacy in reversing rivaroxaban. Due to its low plasma protein binding, dabigatran could be also dialyzed in urgent cases. Clinically relevant non-major bleedings and minor bleedings should be treated with general and local measures, respectively, and, when necessary, with dose delay or drug withdrawal. In this article, the Authors describe the practical approach to bleedings occurring during DOACs treatment.

    Several new oral anticoagulants have been studied in the past decade, and have now started to enter the market. These drugs are reported to be as effective as, or more effective than, warfarin. In Australia, the Therapeutic Goods Administration has approved dabigatran, rivaroxaban and apixaban. The use of these newer anticoagulants is likely to increase in time, and it is important for dentists to have a sound understanding of the mechanisms of action, reversal strategies, and management guidelines for patients taking oral anticoagulants. This article discusses the process of coagulation, available anticoagulants and their monitoring and reversal, and provides clinical advice on the management of patients on anticoagulants who require dental treatment. © 2016 Australian Dental Association.

    Existing data on the risk of ischemic stroke in hyperthyroidism-related atrial fibrillation (AF) and the impact of long-term anticoagulation in these patients, particularly those with self-limiting AF, remain inconclusive. Risk of stroke in hyperthyroidism-related AF is the same as nonhyperthyroid counterparts. This was a single-center observational study of 9727 Chinese patients with nonvalvular AF from July 1997 to December 2011. Patients with AF diagnosed concomitantly with hyperthyroidism were identified. Primary and secondary endpoints were defined as hospitalization with ischemic stroke and intracranial hemorrhage in the first 2 years. Patient characteristics, duration of AF, and choice of antithrombotic therapy were recorded. Self-limiting AF was defined as hyperthyroidism and AF at diagnosis. For stroke prevention, 136 and 243 patients (21.1% and 37.9%) were prescribed warfarin and aspirin, respectively, whereas the remaining patients (41.0%) received no therapy. Ischemic stroke occurred in 50 patients (7.8%), and no patient developed hemorrhagic stroke. Patients with CHA2 DS2 -VASc of 0 did not develop stroke. Warfarin effectively reduced the incidence of stroke compared with aspirin or no therapy in patients with CHA2 DS2 -VASc ≥1 and non-self-limiting AF, but not in those with self-limiting AF or CHA2 DS2 -VASc of 0. Presence of hyperthyroidism did not confer additional risk of ischemic stroke compared with nonhyperthyroid AF. Patients with hyperthyroidism-related AF are at high risk of stroke (3.9% per year). Warfarin confers stroke prevention in patients with CHA2 DS2 -VASc ≥1 and non-self-limiting AF. Overall stroke risk was lower in hyperthyroid non-self-limiting AF patients compared with nonhyperthyroid counterparts. © 2015 Wiley Periodicals, Inc.

  14. Will NOACs become the new standard of care in anticoagulation therapy?

    2015-06-01

    Full Text Available Atrial fibrillation is the most common cardiac arrhythmia in the general population, with a prevalence of 1–3%, which increases with age, reaching 15% in elderly people. Prophylaxis of ischemic stroke with warfarin was the gold standard of medical management for many years. On the other hand heparin and warfarin was the main pharmacologic agents for the prophylaxis/treatment of venous thromboembolism. In the last 5 years warfarin is getting replaced by non-vitamin K antagonist oral anticoagulants at least partly. In this article it is attempted to foresee whether new oral anticoagulants will become the new standard of care in anticoagulation therapy.

  15. The future of anticoagulation clinics.

    Science.gov (United States)

    Macik, B Gail

    2003-01-01

    Anticoagulation therapy is the foundation of treatment for thromboembolic disorders; and coumarin derivatives (warfarin in the United States) are the only orally administered anticoagulant medications currently available. Due to the expense and relative difficulties associated with this route of administration, parenteral drugs are not used routinely for long-term therapy, leaving warfarin as the anticoagulant of choice in the outpatient setting. The management of warfarin is problematic, however, due the nuances of its pharmacodynamic and pharmacokinetic profile and the requirement for frequent monitoring of blood levels. Although management by anticoagulation clinics is considered the gold standard for warfarin therapy, management by an anticoagulation clinic may not be the optimal option from a clinician's view and, in many cases, may not be an option at all. Anticoagulation clinics may impinge on the doctor-patient relationship. Difficulties of communication and reimbursement are not ameliorated by a specialty clinic. Innovations in warfarin management, including patient self-management and computerized dosing programs, are alternatives for improved care that are available with or without input by an anticoagulation service. New oral drugs on the horizon do not require the same intensity of monitoring and do not present the same pharmacodynamic problems associated with warfarin. Warfarin will become obsolete in the foreseeable future. If anticoagulation clinics continue, they must re-define their role as the major part of the workload, warfarin management, disappears. To adapt, clinics must strengthen and enhance their role as coordinators and educators, and less so, managers of anticoagulation therapy.

    To determine, in the various medical specialties, the healthcare process for anticoagulated patients with nonvalvular atrial fibrillation, to determine the available and necessary resources and to identify potential areas of improvement in the care of these patients. We performed a cross-sectional survey of primary care and specialised physicians involved in the care of anticoagulated patients. The questionnaires referred to the healthcare process, the indication and prescription of anticoagulant therapy and the barriers and deficiencies present for these patients. A total of 893 physicians participated in the study, 437 of whom worked in primary care and 456 of whom were specialists (mostly cardiologists). Forty-two percent of the family doctors indicated that they assessed and prescribed anticoagulant therapy, and 66% performed the regular follow-up of these patients. In both healthcare settings, the physicians noted the lack of standardised protocols. There was also a lack of quality control in the treatment. The role of primary care in managing anticoagulated patients has grown compared with previous reports. The responses of the participating physicians suggest marked gaps in the standardisation of the healthcare process and several areas for improvement in these patients' follow-up. The promotion of training in direct-acting anticoagulant drugs remains pivotal. Copyright © 2017 Elsevier España, S.L.U. and Sociedad Española de Medicina Interna (SEMI). All rights reserved.

    Objective: To investigate the anatomical distribution of acute deep venous thrombosis (DVT) of the lower extremity, and compare different therapeutic methods including anticoagulation alone, thrombolysis through dorsal vein and interventional therapy. Methods: The clinical data, venography and therapies of 204 acute DVT patients were retrospectively studied According to the distribution, DVT were classified into three types including peripheral, central and mixed types. According to the difference of the therapeutic method, each type of DVT was divided into three groups, Group A (37 patients) anticoagulation alone: Group B (55 patients) thrombolysis through dorsal vein: and Group C (112 patients) interventional therapy. The results of different kind of treatment method in each type of DVT were evaluated before the patients were discharged and the Chi-square test was used for statistical analysis. Results: There were 132 patients with DVT in the left lower extremity, 62 in right lower extremity, and 10 in both extremities.. The complication of pulmonary embolism (PE) occurred in 4, 5 and 2 cases respectively, and the morbidity was 3.0%, 8.1% and 20.0% (χ 2 =6.494, P=0.039) respectively. There was significant statistical difference among them. There were 23 cases of peripheral type of DVT, 48 central type and 133 mixed type. The complication of PE were observed in 2, 5 and 4 cases respectively in each type. The morbidity was 8.7%, 10.4% and 3.0% respectively (χ 2 =4.350, P=0.114). There were no statistical significance among them. In the 23 cases of peripheral type DVTs, 2 of 5 in group A and 11 of 18 in group B had excellent therapeutic response. In the 48 cases of central type of DVTs, 1 of 10 in group A, 2 of 5 in in group B and 26 of 33 in group C had excellent therapeutic response. There were statistically significant differences among groups A, B and C (χ 2 =16.157, P=0.000). In the 133 cases of mixed type DVTs, 1 of 22 in group A, 10 of 32 in group B and 65

    Full Text Available Objective: To investigate the efficacy and safety of regional citrate anticoagulation (RCA in continuous renal replacement therapy (CRRT for critical patients. Methods: A total of 83 critical patients need CRRT in the intensive care units of our hospital from July 2012 to June 2016 were recruited in the study, and the patients were divided into two groups randomly, the patients in observation group received the RCA treatment, and the patients in control group received traditional low molecular heparin anticoagulation. The difference of safety indicators, biochemical indicators, extracorporeal circulation blood coagulation condition and complications in patients were determined between two groups. Results: Compared with control group, the patients in observation group had an elevated level of iCa2+, the level of chloride ion reduced, the use time of filter increased, the bleeding cases reduced, the concentrations of urea nitrogen, creatinine TNF-α , IL-1β, IL-8 and NO were all significantly downregulated, the data have a significant difference (P < 0.05. Conclusions: RCA is a safe and effective method for CRRT in patients with a high risk of bleeding.

  20. D-dimer: a useful tool in gauging optimal duration of oral anticoagulant therapy?

    Directory of Open Access Journals (Sweden)

    M. Silingardi

    2013-05-01

    Full Text Available BACKGROUND AND AIM OF THE STUDY Optimal duration of oral anticoagulant therapy (OAT in idiopathic venous thromboembolism (VTE is unknown. Indefinite OAT carries an unacceptable risk of major bleeding and prospective studies have demonstrated that OAT is no longer protective after its withdrawal. How to identify the patients at risk for recurrence? D-dimer is a marker of thrombin activity. Early prospective studies showed that elevated D-dimer levels after anticoagulation had a highly predictive value for a recurrent episode. Does D-dimer assay have a role in gauging the appropriate duration of anticoagulant therapy? The PROLONG study tries to answer this question. METHOD D-dimer assay was performed one month after stopping anticoagulation. Patiens with normal D-dimer levels did not resume anticoagulation while patients with elevated D-dimer levels were randomized to discontinue or resume anticoagulation. Study end-points was the composite of recurrent VTE and major bleeding during an average follow-up of 1.4 years. RESULTS The rate of recurrence is significantly higher in patients with elevated D-dimer levels who discontinued anticoagulation. Resuming anticoagulation in this cohort of patients markedly reduces recurrent events without increasing major bleeding. DISCUSSION AND CONCLUSIONS PROLONG study is provocative, because D-dimer assay is simple, thus not requiring dedicated laboratory facilities. D-dimer test has otherwise high sensitivity but low specificity in VTE diagnosis. Aspecifically elevated D-dimer levels are available in the elderly and the majority of patients included in the study were > 65 years old, thus introducing a possible selection bias. Nonetheless the results of the study are useful for the clinician. Prolongation of vitamin K antagonists in patients with elevated D-dimer levels one month after discontinuation of OAT for a first unprovoked episode of VTE results in a favourable risk-benefit relationship. Probably this

    A growing number of premenopausal women are currently using antithrombotic and/or (dual) antiplatelet therapy for various cardiovascular indications. These may induce or exacerbate abnormal uterine bleeding and more awareness and knowledge among prescribers is required. Heavy and irregular menstrual bleeding is common in women in their forties and may have a variety of underlying causes that require different treatment options. Thus using anticoagulants in premenopausal women demands specific expertise and close collaboration between cardiovascular physicians and gynecologists. In this article we summarize the scope of the problem and provide practical recommendations for the care for young women taking anticoagulants and/or (dual) antiplatelet therapy. We also recommend that more safety data on uterine bleeding with novel anticoagulants in premenopausal women should be obtained. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    1993-06-01

    The classical management of patients on oral anticoagulant therapy included hospitalisation, cessation of the anticoagulant agent, and extraction of teeth when the prothrombine levels rise. This method was substituted in the High Risk Dental Clinic at Barzilai Medical Center in Ashkelon by use of a tissue sealant (Tisseel) which does not need hospitalisation nor cessation of the anticoagulant therapy. In comparing the last 23 sessions employing the former method to the first 23 sessions using the new method there were significant differences in the cost effectiveness for the health system, provider, insurer and patient. Despite the fact that from the health system point of view the new method is much more cost effective, there is no financial incentive for the provider (hospital) nor awareness on the part of the insurer (General Sick Fund) to embrace it and 'market' it.

  3. Atrial fibrillation and stroke prevention practices in patients with candidacy for anticoagulation therapy

    Ullah, I.; Ahmad, S.; Hayat, Y.

    2015-01-01

    Background: Stroke secondary to Atrial Fibrillation is usually due to thrombi formed in the left atrium and left atrial appendage embolizing to cause ischemic stroke. Therefore, in patients with Atrial Fibrillation, antithrombotic therapy is recommended to prevent stroke. Vitamin K antagonist therapy is most widely used antithrombotic therapy for patients with valvular and non valvular AF. Aspirin is recommended only in low risk patients. This study was conducted to determine the stroke prevention practices in local patients with atrial fibrillation who were candidates for anticoagulation therapy. Method: This was descriptive cross sectional study conducted at Cardiovascular Department Lady Reading Hospital Peshawar and Cardiology Department Hayatabad Medical Complex Peshawar. Sampling technique was non probability consecutive. Patients visiting OPD of respective hospitals with EKG evidence of AF and having CHADES VASC score 2 or more or having mitral stenosis and AF were included in the study. Patients with additional indications for anticoagulation were excluded from the study. Results: A total of 205 patients with atrial fibrillation were studied. Mean age was 60.7±14.7 years. Male were 55.6 percentage (n=114) while 44.4 percentage (n=91) were female. Of these 149 (72.7 percentage) were candidates for anticoagulation based on CHA2DS2 VASc score of 2 and more or mitral stenosis with AF. Only 27.5 percentage (n=41) patients were adequately treated with anticoagulant therapy using VKA or novel oral anticoagulant drugs. Majority of them were getting dual antiplatelet therapy (DAPT). Conclusion: Most patients with AF and high risk characteristics for thromboembolism are not receiving proper stroke prevention therapies. (author)

    Women receiving vitamin K antagonists (VKAs) require adequate contraception because of the potential for fetal complications. It is unknown whether the use of hormonal therapy, especially those containing estrogens, is associated with recurrent venous thromboembolism (VTE) during anticoagulation. Despite the absence of data, World Health Organization guidelines state that use of estrogen-containing contraceptives confers an "unacceptable health risk" during established anticoagulation for VTE. We compared the incidences of recurrent VTE and abnormal uterine bleeding with and without concomitant hormonal therapy in women aged abnormal uterine bleeding. In total, 1888 women were included. VTE incidence densities on and off hormonal therapy were 3.7%/year and 4.7%/year (adjusted HR, 0.56; 95% confidence interval [CI], 0.23-1.39), respectively, and were 3.7%/year and 3.8%/year, respectively, for estrogen-containing and progestin-only therapy. The adjusted HR for all abnormal uterine bleeding (on vs off hormonal therapy) was 1.02 (95% CI, 0.66-1.57). Abnormal uterine bleeding occurred more frequently with rivaroxaban than with enoxaparin/VKA (HR, 2.13; 95% CI, 1.57-2.89). Hormonal therapy was not associated with an increased risk of recurrent VTE in women receiving therapeutic anticoagulation. The observed increased risk of abnormal uterine bleeding with rivaroxaban needs further exploration. © 2016 by The American Society of Hematology.

    Heparin, despite its significant side-effects, is the most commonly used anticoagulant for continuous renal replacement therapy in critical care setting. In recent years, citrate has gained much popularity by improving continuous renal replacement therapy circuit survival and decreasing blood transfusion requirements. However, its complex metabolic consequences warrant modification in the design of the citrate-based continuous renal replacement therapy protocol. With thorough understanding of the therapeutic mechanism of citrate, a simple and practicable protocol can be devised. Citrate-based continuous renal replacement therapy can be safely and widely used in the clinical setting with appropriate clinical staff training.

  7. Aneurysmal subarachnoid hemorrhage in patients taking direct oral anticoagulants: A case series and discussion of management

    Directory of Open Access Journals (Sweden)

    Joseph H. McMordie, MD

    2018-03-01

    Full Text Available Direct oral anticoagulants are becoming more commonplace for the treatment of nonvalvular atrial fibrillation and deep vein thrombosis. Unfortunately, effective reversal agents are not widely available limiting options for neurosurgical intervention during active anticoagulation. We report a case series of 3 patients treated for aneurysmal subarachnoid hemorrhage while taking direct oral anticoagulants. All three underwent open surgical clipping after adequate time was allowed for drug metabolism. Decision-making must take into account timing of intervention, drug half-life, and currently available reversal agents.

  8. Is Endoscopic Therapy Safe for Upper Gastrointestinal Bleeding in Anticoagulated Patients With Supratherapeutic International Normalized Ratios?

    The management of upper gastrointestinal bleeding (UGIB) in anticoagulated patients with supratherapeutic international normalized ratios (INRs) presents a challenge. The purpose of the study was to evaluate the safety of endoscopic therapy for UGIB in anticoagulated patients with supratherapeutic INR in terms of rebleeding and therapeutic outcomes. One hundred ninety-two anticoagulated patients who underwent endoscopic treatment for UGIB were enrolled in the study. Patients were divided into 2 groups based on the occurrence of rebleeding within 30 days of the initial therapeutic endoscopy: no-rebleeding group (n = 168) and rebleeding group (n = 24). The overall rebleeding rate was 12.5%. Bleeding from gastric cancer and bleeding at the duodenum were significantly related to rebleeding in a univariate analysis. Multivariate analysis determined that presenting symptoms other than melena (hematemesis, hematochezia, or others) (odds ratio, 3.93; 95% confidence interval, 1.44-10.76) and bleeding from gastric cancer (odds ratio, 6.10; 95% confidence interval, 1.27-29.25) were significant factors predictive of rebleeding. Supratherapeutic INR at the time of endoscopic therapy was not significantly associated with rebleeding in either univariate or multivariate analysis. Significant differences in bleeding-related mortality, additional intervention to control bleeding, length of hospital stay, and transfusion requirements were revealed between the rebleeding and no-rebleeding groups. There were no significant differences in therapeutic outcomes between patients with INR within the therapeutic range and those with supratherapeutic INR. Supratherapeutic INR at the time of endoscopic therapy did not change rebleeding and therapeutic outcomes. Thus, we should consider endoscopic therapy for UGIB in anticoagulated patients, irrespective of INR at the time of endoscopic therapy.

    This study evaluated the use of an artificial intelligence platform on mobile devices in measuring and increasing medication adherence in stroke patients on anticoagulation therapy. The introduction of direct oral anticoagulants, while reducing the need for monitoring, have also placed pressure on patients to self-manage. Suboptimal adherence goes undetected as routine laboratory tests are not reliable indicators of adherence, placing patients at increased risk of stroke and bleeding. A randomized, parallel-group, 12-week study was conducted in adults (n=28) with recently diagnosed ischemic stroke receiving any anticoagulation. Patients were randomized to daily monitoring by the artificial intelligence platform (intervention) or to no daily monitoring (control). The artificial intelligence application visually identified the patient, the medication, and the confirmed ingestion. Adherence was measured by pill counts and plasma sampling in both groups. For all patients (n=28), mean (SD) age was 57 years (13.2 years) and 53.6% were women. Mean (SD) cumulative adherence based on the artificial intelligence platform was 90.5% (7.5%). Plasma drug concentration levels indicated that adherence was 100% (15 of 15) and 50% (6 of 12) in the intervention and control groups, respectively. Patients, some with little experience using a smartphone, successfully used the technology and demonstrated a 50% improvement in adherence based on plasma drug concentration levels. For patients receiving direct oral anticoagulants, absolute improvement increased to 67%. Real-time monitoring has the potential to increase adherence and change behavior, particularly in patients on direct oral anticoagulant therapy. URL: http://www.clinicaltrials.gov.

    Whether women developing venous thromboembolism (VTE) while using hormonal therapy should be classified as having "unprovoked" or "provoked" VTE is controversial. We used the RIETE (Registro Informatizado Enfermedad TromboEmbólica) database to compare the rate of symptomatic VTE recurrences after discontinuing anticoagulation in 3 subgroups of women aged ≤50years without cancer, pregnancy or puerperium: (1) those with hormonal therapy and no additional risk factors (hormonal users only); (2) those with unprovoked VTE; and (3) those with additional risk factors, with or without hormonal therapy. As of March 2016, 1513 women had been followed-up for at least one month after discontinuing anticoagulation. Of these, 654 (43%) were hormonal users only, 390 (26%) had unprovoked VTE and 469 (31%) had transient risk factors with or without hormonal therapy. After discontinuing anticoagulation, the rate of VTE recurrences in women with hormonal use only (2.44 per 100 patient-years; 95% CI: 1.53-3.69) was significantly lower than in those with unprovoked VTE (6.03; 95% CI: 3.97-8.77) and similar to those with transient risk factors (2.58; 95% CI: 1.50-4.13). Interestingly, the rate of VTE recurrences presenting as pulmonary embolism in women with hormonal use only (0.55 per 100 patient-years; 95% CI: 0.18-1.29) was similar to those with transient risk factors (0.46; 95% CI: 0.09-1.33) and 4-fold lower than in women with unprovoked VTE (2.23; 95% CI: 1.07-4.10). After discontinuing anticoagulation, the rate of VTE recurrences in hormonal users only was significantly lower than in women with unprovoked VTE and similar to the rate in women with additional risk factors. © 2017 Elsevier Ltd.

    Resources devoted to health care are limited, therefore setting priorities is required. It differs between countries whether decision-making concerning health care technologies focus on broad economic perspectives or whether focus is narrow on single budgets ("silo mentality"). The cost perspective as one part of the full health economic analysis is important for decision-making. With the case of oral anticoagulants in patients with nonvalvular atrial fibrillation (NVAF), the aim is to discuss the implication of the use of different cost perspectives for decision-making and priority setting. In a cost analysis, the annual average total costs of five oral anticoagulants (warfarin and non-vitamin K oral anticoagulants [NOACs; dabigatran, rivaroxaban, apixaban, and edoxaban]) used in daily clinical practice in Denmark for the prevention of stroke in NVAF patients are analyzed. This is done in pairwise comparisons between warfarin and each NOAC based on five potential cost perspectives, from a "drug cost only" perspective up to a "societal" perspective. All comparisons of warfarin and NOACs show that the cost perspective based on all relevant costs, ie, total costs perspective, is essential for the choice of therapy. Focusing on the reimbursement costs of the drugs only, warfarin is the least costly option. However, with the aim of therapy to prevent strokes and limit bleedings, including the economic impact of this, all NOACs, except rivaroxaban, result in slightly lower health care costs compared with warfarin. The same picture was found applying the societal perspective. Many broad cost-effectiveness analyses of NOACs exist. However, in countries with budget focus in decision-making this information does not apply. The present study's case of oral anticoagulants has shown that decision-making should be based on health care or societal cost perspectives for optimal use of limited resources. Otherwise, the risk is that suboptimal decisions will be likely.

    Full Text Available Introduction: The risk of postoperative hemorrhage from oral surgical procedures has been a concern in the treatment of patients who are receiving long-term anticoagulation therapy. A study undertaken in our institution to address questions about the amount and severity of bleeding associated with minor outpatient oral surgery procedures by assessing bleeding in patients who did not alter their anticoagulant regimen. Subjects and Methods: Eighty-three patients receiving long-term anticoagulant therapy visited Department of Oral and Maxillofacial Surgery from May 2010 to October 2011 for extractions and minor oral surgical procedures. Each patient was required to undergo preoperative assessment of prothrombin time (PT and measurement of the international normalized ratio. Fifty-six patients with preoperative PT values within the therapeutic range 3-4 were included in the study. The patients′ age ranged between 30 and 75 years. Application of surgispon was done following the procedure. Extraction of teeth performed with minimal trauma to the surrounding tissues, the socket margins sutured, and sutures removed after 5 days. Results: There was no significant incidence of prolonged or excessive hemorrhage and wound infection and the healing process was normal.

    Full Text Available Aim: The optimal therapeutic range for INR of the patient who were on warfarin therapy is narrow. There are various methods of INR monitoring to adjust the appropriate dosage of warfarin therapy. This study aims to test the reliability of POC (Point of care devices used for INR(International normalized ratio monitoring. Material and Method: Forty six  patients who were on warfarin therapy for any reasons were enrolled for this study. Their INR  were divided into 3 groups according to their laboratory INR results. Grup 1 had INR results lower than 2, group 2 had INR levels of 2 to 3.5, group 3 had INR levels of higher than 3.5 INR of the patients were remeasured with the POC device.  Results: The ages of the patients were between 24 to 84. Twenty six patients were male and 20 were female. The mean INR level of laboratory measurements was 1.26 in group 1 whereas it was 1.45 for POC device measurements. There were not statistically significant difference between two devices for group 1 (p=0.15. In group 2 the mean INR levels were measured by laboratory instrument and POC device were 2.74 and 3.51 respectively (p=0,01. In group 3 mean INR levels were measured by laboratory instrument and POC device were 4.27 and 5.25 respectively (p=0.01. Discussion: We suppose it is rational to adjust warfarin dosage by specialists using laboratory results in order to prevent hemorrhagic and thromboembolic complications.

    In developed countries, the incidence of cardiovascular disease is increasing, therefore, anticoagulant and antiplatelet drugs are a widespread treatment nowadays. Percutaneous nephrolithotomy (PNL) is the first-line treatment for large or complex stones (> 2 cm) and remains an alternative for the smaller ones. The objective of this study is to analyze whether PNL surgery is a safe procedure in patients under a treatment discontinuation protocol for anticoagulant or antiplatelet therapies. We retrospectively studied 301 patients who underwent PNL in our hospital between 2008 and 2016 and identified 46 patients on chronic antiplatelet or anticoagulation treatment. With respect to PNL outcomes, the stone-free rate was similar (78 vs 74%, p = 0.762) in both groups, without any significant differences in the overall postoperative complications (17 vs 26%, p = 0.203). The incidence of hemorrhagic complications was similar between groups (12 vs 9%, p = 0.492), as demonstrated by the mean drop in hemoglobin (Hb), which was comparable in both cohorts (2.2 ± 1.3 vs 2.0 ± 1.4 p = 0.270) and the blood transfusion rate (14% in group A and 8% in group B, p = 0.205). No thromboembolic events were found within the year after the PNL procedure. PNL is a safe and effective intervention in patients under a treatment discontinuation protocol for anticoagulant or antiplatelet therapies. Although our study demonstrates the feasibility of this protocol, new scientific evidence aims to stratify the thromboembolic and bleeding risk of each patient to individualize the perioperative management thereafter.

    Full Text Available Background: Oral anticoagulation treatment (OAT such as warfarin therapy is recommended for older adults with atrial fibrillation, heart failure, or who are at risk for venous thromboembolism. Despite its proven benefits, older adults report both dissatisfaction with OAT and reduced quality of life that can potentially lead to low adherence to OAT and decreased treatment efficacy. Objective: To test the feasibility of Mobile Applications for Seniors to enhance Safe anticoagulation therapy (MASS, a mobile-based health technology intervention designed to promote independence and self-care. Method s: This pilot study used a single-arm experimental pre–post design to test the feasibility of a 3-month intervention using MASS in 18 older adults (male: n = 14; White: n = 9; Hispanic: n = 7; Other: n = 2; M age = 67. MASS was available in English or Spanish. Participants completed surveys about their OAT knowledge, attitudes, quality of life with OAT, and adherence at baseline and at a 3-month follow-up. Satisfaction with the MASS intervention was also assessed at follow-up. Results: Anticoagulation knowledge significantly improved from baseline to follow-up ( M base = 12.5 ± 5.51, M follow-up = 14.78 ± 3.93, p = .007. Other outcomes were not different, pre- and post-tests. Participants reported they were generally satisfied with MASS, its ease of use and its usefulness. Conclusion: The results showed use of MASS improved older adults’ knowledge of OAT. Using mHealth apps may enhance self-care among older adults with chronic conditions who are also taking oral anticoagulants.

    As about 50 % of patients with unprovoked venous thromboembolism (VTE) will develop new episodes after discontinuing therapy, indefinite treatment is suggested in patients with low or moderate bleeding risk. Baseline and post-baseline factors can help clinicians to identify patients at high risk of recurrence, who require extended treatment. Residual vein obstruction and D-dimer assay have been shown to be suitable methods for assessing the risk of VTE recurrences after a first unprovoked VTE. In treatment for VTE the use of direct oral anticoagulants (DOAC) is growing instead of the standard adjusted dose of vitamin K antagonists. The DOAC safety profile has recently been strengthened with systematic reviews and meta-analyses. Idarucizumab is only approved for the reversal of dabigatran etexilate; intravenous antidotes for factor Xa inhibitors are under development. Their advent is of great interest. In the extended treatment of VTE sulodexide has been demonstrated to significantly decrease the risk of recurrences with an excellent safety profile. Aspirin is substantially less effective than oral anticoagulants in preventing recurrences but could play a role among patients who decided to stop anticoagulants. In conclusion, for the secondary prevention of VTE several options are available, without a recognised best choice regarding the treatment duration and the choice of drugs. An individual strategy taking into account risk of recurrence, bleeding risk, therapeutic options, and patient preferences is appropriate.

  17. Improvement in long-term ECMO by detailed monitoring of anticoagulation: a case report.

    The use of unfractionated heparin (UFH) as an anticoagulant during long-term extracorporeal support presents a unique challenge for the clinician in balancing the amount of anticoagulant to maintain adequate anticoagulation without causing excessive bleeding. Activated clotting times (ACT) and activated partial thromboplastin times (aPTT) are the most common modality to monitor UFH on extracorporeal membrane oxygenation (ECMO). Limitations to these tests include consumptive coagulopathies, clotting factor deficiencies, platelet dysfunction, and fibrinolysis. The following case report describes the use of alternative monitoring strategies to assess more accurately anticoagulation during ECMO. A 20-month-old female presented to the emergency department with a 5-6 day history of cough, fever, tachypnea, and respiratory distress. She was diagnosed with influenza A and B with pneumonia. The patient was placed on veno-venous ECMO (V-V ECMO) after mechanical ventilation failed. On ECMO day eight, the patient developed a thrombus in her inferior vena cava and pleural effusions, obstructing cannula flow. Laboratory tests revealed the ACT was within range, yet the aPTT was dropping, despite increased heparin. Heparin levels were low and antithrombin-III (AT) concentrations were 40%. Recombinant AT was given and subsequent aPTTs were within the therapeutic range. Later, the aPTT decreased to 475 mg/ dL, and Factor VIII >150 IU/dL, suggesting an acute phase reaction or ongoing systemic inflammation, increasing the risk for thrombosis. We maintained heparin assays between 0.5-0.7 IU/mL and AT >60% to assure heparin's effect. The patient showed no signs of excess bleeding, blood product administration, or clots in the circuit, suggesting proper anticoagulation. The patient was successfully weaned on day 33 and is currently alive and at home. Monitoring of anti-Xa UFH and AT proved effective for measuring anticoagulation and detecting inconsistencies in other anticoagulation

    Background Updated evidence-based guidelines for the management of atrial fibrillation (AF) necessitate patient review, particularly with respect to oral anticoagulants, to ensure maximum health gain around stroke prophylaxis. Objective To quantify the level of anticoagulation utilisation in patients with a CHA 2 DS 2 -VASc ≥1/≥2 (male/female) according to evidence-based guidelines and to assess the impact of a pharmacist-led intervention to optimise therapy. Setting Fifteen general medical practices in Liverpool, North-West England with a practice population of 99,129. Method GRASP-AF software was employed to interrogate patient electronic medical records to identify and risk stratify AF patients (using CHA 2 DS 2 -VASc). A pharmacist then reviewed the medical records of those of patients not anticoagulated and with a CHA 2 DS 2 -VASc ≥1/≥2 (male/female). Recommendations were discussed with a general practitioner (GP) and those patients in whom the need for anticoagulation was agreed were invited for a consultation with either the pharmacist or GP and therapy optimised where appropriate. The GPs were responsible for managing those patients referred for diagnosis confirmation or further specialist opinion. Main outcome measure Proportion of patients eligible/not eligible for anticoagulation; proportions in whom anticoagulants initiated, refused, antiplatelets discontinued. Results Five hundred and twenty-three patients (31% of patients identified with AF and a CHA 2 DS 2 -VASc ≥1/≥2 (male/female)) were not receiving an anticoagulant (26 subsequently died or left the practice leaving 497). Three hundred and eighty-two (77%) pharmacist recommendations to a GP were agreed without modification. Following outcomes of diagnostic investigations and specialist referrals, 202 (41%) patients were candidates for anticoagulation, 251 (51%) were not eligible for anticoagulation, 103 (21%) were anticoagulated (56 warfarin, 47 DOAC). Conclusion A pharmacist

    Clinicians should be aware of new developments to familiarize themselves with pharmacokinetic and pharmacodynamic characteristics of new anticoagulant agents to appropriately and safely use them. For the moment, cardiologists and other clinicians also require to master currently available drugs, realizing the mechanism of action, side effects, and laboratory monitoring to measure their anticoagulant effects. Warfarin and heparin have narrow therapeutic window with high inter- and intra-patient variability, thereby the use of either drug needs careful laboratory monitoring and dose adjustment to ensure proper antithrombotic protection while minimizing the bleeding risk. The prothrombin time (PT) and the activated partial thromboplastin time (aPTT) are laboratory tests commonly used to monitor warfarin and heparin, respectively. These two tests depend highly on the combination of reagent and instrument utilized. Results for a single specimen tested in different laboratories are variable; this is mostly attributable to the specific reagents and to a much lesser degree to the instrument used. The PT stands alone as the single coagulation test that has undergone the most extensive attempt at assay standardization. The international normalized ratio (INR) was introduced to "normalize" all PT reagents to a World Health Organization (WHO) reference thromboplastin preparation standard, such that a PT measured anywhere in the world would result in an INR value similar to that which would have been achieved had the WHO reference thromboplastin been utilized. However, INRs are reproducible between laboratories for only those patients who are stably anticoagulated with vitamin K antagonists (VKAs) (i.e., at least 6 weeks of VKA therapy), and are not reliable or reproducible between laboratories for patients for whom VKA therapy has recently been started or any other clinical conditions associated with a prolonged PT such as liver disease, disseminated intravascular coagulation

    Anticoagulation therapy is a life-enhancing therapy for patients who are at risk for embolic events secondary to atrial fibrillation, valve replacement, and other comorbidities. Clinicians are motivated to decrease the amount of time that patients are either under- or over-anticoagulated, common conditions that decrease patient safety at either extreme. The primary purpose of this descriptive study was to examine the relationship between personal life event factors as measured by Norbeck's Life Events Questionnaire, core demographics such as age and income, and anticoagulation regulation. Although many factors affect anticoagulation therapy, the precise impact of life events, positive or negative, is unknown. The salient findings of this study (n = 202) showed a small, though statistically significant, inverse relationship (r = -0.184, P < .01) between negative life events and decreased time within therapeutic international normalized ratio. Total Life Event scores showed a statistically significant inverse relationship (r = -0.159, P < .05) to international normalized ratio time within therapeutic level. Lower income was inversely associated with higher negative Life Event scores (r = -0.192, P < .01). The findings demonstrate the need for strategies that address the potential impact of life events in conjunction with coexisting screening measures used in anticoagulation clinics. Implications for this study are limited by lack of methodology documenting concurrent social support factors and limitations of the research tool to reflect life event issues specific to outpatient seniors.

    Fall risk for older adults is a multi-factorial public health problem as 90% of geriatric injuries are caused by traumatic falls. The CDC estimated 33% of adults >65 years incurred a fall in 2011, with 30% resulting in moderate injury. While much has been written about overall risk to trauma patients on oral anticoagulant (OAC) therapy, less has been reported on outcomes in the elderly trauma population. We used data from the National Trauma Data Bank (NTDB) to identify the types of injury and complications incurred, length of stay, and mortality associated with OACs in elderly patients sustaining a fall. Using standard NTDB practices, data were collected on elderly patients (≥65 years) on OACs with diagnosis of fall as the primary mechanism of injury from 2007 to 2010. Univariate analysis was used to determine patient variables influencing risk of fall on OACs. Odds ratios were calculated for types of injury sustained and post-trauma complications. Logistic regression was used to determine mortality associated with type of injury incurred. Of 118,467 elderly patients sampled, OAC use was observed in 444. Predisposing risk factors for fall on OACs were >1 comorbidity (p3 complications (p<0.0001); the most significant being ARDS and ARF (p<0.0001). The mortality rate on OACs was 16%. Injuries to the GI tract, liver, spleen, and kidney (p<0.0002) were more likely to occur. However, if patients suffered a mortality, the most significant injuries were skull fractures and intracranial haemorrhage (p<0.0001). Risks of anticoagulation in elderly trauma patients are complex. While OAC use is a predictor of 30-day mortality after fall, the injuries sustained are markedly different between the elderly who die and those who do not. As a result there is a greater need for healthcare providers to identify preventable and non-preventable risks factors indicative of falls in the anti-coagulated elderly patient.

    Full Text Available Systemic heparinization during continuous renal replacement therapy (CRRT is associated with disadvantage of risk of bleeding. This study analyses the efficacy of frequent saline flushes compared with heparin anticoagulation to maintain filter life. From January 2004 to November 2007, 65 critically ill patients with acute renal failure underwent CRRT. Continuous venovenous hemodialfiltration (CVVHDF was performed using Diapact Braun CRRT machine. 1.7% P.D. fluid was used as dialysate. 0.9% NS with addition of 10% Ca Gluconate, Magnesium Sulphate, Soda bicarbonate and Potassium Chloride added sequentially in separate units were used for replacement, carefully monitoring their levels. Anticoagulation of extracorporeal circuit was achieved with unfractionated heparin (250-500 units alternate hour in 35 patients targeting aPTT of 45-55 seconds. No anticoagulation was used in 30 patients with baseline APTT > 55 seconds and extracorporeal circuit was maintained with saline flushes at 30 min interval. 65 pa-tients including 42 males. Co-morbidities were comparable in both groups. HMARF was signifi-cantly more common in heparin group while Sepsis was comparable in both the groups. CRRT parameters were similar in both groups. Average filter life in heparin group was 26 ± 6.4 hours while it was 24.5 ± 6.36 hours in heparin free group ( P=NS. Patients receiving heparin had 16 bleeding episodes (0.45/patient while only four bleeding episodes occurred in heparin free group (0.13/patient, P< 0.05. Mortality was 71% in heparin group and 67% in heparin free group. Frequent saline flushes is an effective mode of maintainance of extracorporeal circuit in CRRT when aPTT is already on the higher side, with significantly decreased bleeding episodes.

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

    Previous research suggests uncertainty whether or not there is any additional benefit in adding antiplatelet therapy (APT) to anticoagulation therapy (ACT) in patients with high-risk atrial fibrillation (AF) in terms of reduction in vascular events, including stroke. The existing guidelines acknowledge an increased risk of bleeding associated with such a strategy; however, there is no consensus on the treatment pathway. To determine, by undertaking a systematic review, if the addition of APT to ACT is beneficial compared with ACT alone in patients with AF who are considered to be at high risk of thromboembolic events (TEs). Data sources included bibliographic databases {the Cochrane Library [Cochrane Central Register of Controlled Trials (CENTRAL)], MEDLINE, MEDLINE In-Process and Other Non-Indexed Citations, EMBASE, ClinicalTrials.gov, National Institute for Health Research (NIHR) Clinical Research Network Portfolio, Current Controlled Trials (CCT) and the World Health Organization International Clinical Trials Registry Platform (WHO ICTRP)}, reference lists from identified systematic reviews and relevant studies, and contact with clinical experts. Searches were from inception to September 2010 and did not use language restrictions or study design filters. Studies of any design were included to evaluate clinical effectiveness, including randomised controlled trials (RCTs), non-randomised comparisons, cohort studies, case series or registries, longitudinal studies, systematic reviews and meta-analyses, and conference abstracts published after 2008. Inclusion criteria consisted of a population with AF, at high-risk of TEs, aged ≥ 18 years, on combined ACT and APT compared with others on ACT alone or ACT plus placebo. Inclusion decisions, assessment of study quality and data extraction were undertaken using methods to minimise bias. Fifty-three publications were included, reporting five RCTs (11 publications), 18 non-randomised comparisons (24 publications) and 18

    2010-01-01

    Purpose: To characterize the bleeding toxicity associated with external beam radiotherapy for prostate cancer patients receiving anticoagulation (AC) therapy. Methods and Materials: The study cohort consisted of 568 patients with adenocarcinoma of the prostate who were treated with definitive external beam radiotherapy. Of these men, 79 were receiving AC therapy with either warfarin or clopidogrel. All patients were treated with three-dimensional conformal radiotherapy or intensity-modulated radiotherapy. Bleeding complications were recorded during treatment and subsequent follow-up visits. Results: With a median follow-up of 48 months, the 4-year actuarial risk of Grade 3 or worse bleeding toxicity was 15.5% for those receiving AC therapy compared with 3.6% among those not receiving AC (p < .0001). On multivariate analysis, AC therapy was the only significant factor associated with Grade 3 or worse bleeding (p < .0001). For patients taking AC therapy, the crude rate of bleeding was 39.2%. Multivariate analysis within the AC group demonstrated that a higher radiotherapy dose (p = .0408), intensity-modulated radiotherapy (p = 0.0136), and previous transurethral resection of the prostate (p = .0001) were associated with Grade 2 or worse bleeding toxicity. Androgen deprivation therapy was protective against bleeding, with borderline significance (p = 0.0599). Dose-volume histogram analysis revealed that Grade 3 or worse bleeding was minimized if the percentage of the rectum receiving ≥70 Gy was <10% or the rectum receiving ≥50 Gy was <50%. Conclusion: Patients taking AC therapy have a substantial risk of bleeding toxicity from external beam radiotherapy. In this setting, dose escalation or intensity-modulated radiotherapy should be used judiciously. With adherence to strict dose-volume histogram criteria and minimizing hotspots, the risk of severe bleeding might be reduced.

    In 2011 we reviewed clinical updates and controversies surrounding anticoagulation bridge therapy in patients with atrial fibrillation (AF). Since then, options for oral anticoagulation have expanded with the addition of four direct oral anticoagulant (DOAC) agents available in the United States. Nonetheless, vitamin K antagonist (VKA) therapy continues to be the treatment of choice for patients who are poor candidates for a DOAC and for whom bridge therapy remains a therapeutic dilemma. This literature review identifies evidence and guideline and consensus statements from the last 5 years to provide updated recommendations and insight into bridge therapy for patients using a VKA for AF. Since our last review, at least four major international guidelines have been updated plus a new consensus document addressing bridge therapy was released. Prospective trials and one randomized controlled trial have provided guidance for perioperative bridge therapy. The clinical trial data showed that bridging with heparin is associated with a significant bleeding risk compared with not bridging; furthermore, data suggested that actual perioperative thromboembolic risk may be lower than previously estimated. Notably, patients at high risk for stroke have not been adequately represented. These findings highlight the importance of assessing thrombosis and bleeding risk before making bridging decisions. Thrombosis and bleeding risk tools have emerged to facilitate this assessment and have been incorporated into guideline recommendations. Results from ongoing trials are expected to provide more guidance on safe and effective perioperative management approaches for patients at high risk for stroke. © 2017 Pharmacotherapy Publications, Inc.

    Full Text Available [english] Background: Anticoagulation is a crucial element in microsurgery. Although various clinical studies and international surveys have revealed that anticoagulation strategies can vary and result in similar outcomes, anticoagulative regimen are far away from standardization. In Germany and german speaking countries standardized anticoagulation protocols concerning free flap surgery do not exist so far. Methods: To evaluate the current practice of clinics in Germany, Austria and Switzerland with specialization in microsurgery we performed a questionnaire surveying the perioperative regimen of anticoagulant and antiplatelet therapy in free flap surgery. The microsurgeons were interrogated on several anticoagulant, rheologic and antiplatelet medications, their dosage and perioperative frequency of application pre-, intra- and postoperative.Results: The questionnaire revealed that the used antithrombotic and perioperative regimens varied from department to department presumably based on the personal experience of the surgeon. Multiple approaches are used with a wide range of anticoagulants used either alone or in combination, with different intervals of application and different dosages. Conclusion: Therefore consensus meetings should be held in future leading to conduct prospective multicenter studies with formulation of standardized anticoagulative and perioperative protocols in microsurgery reducing flap failure to other than pharmacologic reasons.[german] Hintergrund: Die Antikoagulation stellt ein zentrales Element in der Mikrochirurgie dar.

    Full Text Available A 62 year-old caucasian male was admitted in our pulmonary hypertension expert center with initial diagnosis of pulmonary veno-occlusive disease for validation and specific treatment approach. Routine examinations revealed no apparent cause of pulmonary hypertension. Patient was referred for a thorax contrast enhanced multi-slice computed tomography which revealed extensive bilateral thrombi in pulmonary lower lobe arteries, pleading for chronic post embolic lesions. A right heart catheterization and pulmonary angiography confirmed the diagnosis of chronic thromboembolic pulmonary hypertension (CTEPH. Following the local regulations, the patient underwent thrombophilia screening including molecular genetic testing, with positive findings for heterozygous for VCORK1 -1639G>A gene single nucleotide polymorphism, PAI-1 4G/5G and factor II G20210A gene. With heterozygous genetic profile of 3 mutations he has a genetic predisposition for developing a thrombophilic disease which could be involved in the etiology of CTEPH. Familial screening was extended to descendants; the unique son was tested with positive results for the same three genes. Supportive pulmonary hypertension drug therapy was initiated together with patient self-monitoring management of oral anticoagulation therapy. For optimal control of targeted anticoagulation due to a very high risk of thrombotic state the patient used a point-of-care device (CoaguChek®XS System, Roche Diagnostics for coagulation self-monitoring.

    Portal vein thrombosis (PVT) is a common complication following splenectomy in patients with liver cirrhosis and portal hypertension, which also brings difficulties to future possible liver transplantation. This paper retrospectively analyzes the preventive effect of combined anatomic splenectomy and early anticoagulant therapy on post-splenectomy portal vein thrombosis in patients with portal hypertension. We retrospectively analyzed 136 patients who underwent splenectomy at our hospital between January 2010 and December 2013 due to liver cirrhosis and portal hypertension. Patient conditions, such as coagulation function, splenic and portal vein thrombosis, intra-abdominal hemorrhage, pancreatic leakage and intra-abdominal infections, are observed postoperatively. Despite the presence of liver cirrhosis and portal hypertension in patients, early postoperative anticoagulant therapy has no significant impact on coagulation function and intra-abdominal hemorrhage of these patients (p > 0.05). Anatomic splenectomy can reduce the occurrence of complications such as postoperative bleeding, pancreatic leakage and intra-abdominal infections (p splenectomy and early postoperative anticoagulant therapy can reduce post-splenectomy portal vein thrombosis in patients with portal hypertension, and is conducive to the future liver transplantation therapy may be needed by the patients.

We investigated the efficacy and safety of our anticoagulant regimen based on Doppler findings.Methods: Patients aged ≤75 years with metastatic colorectal cancer, no history of thromboembolism, and no prior use of Bev received chemotherapy plus Bev. Doppler ultrasound imaging of the deep venous system to detect thrombosis was performed after the first course of Bev and repeated after the third course in patients with asymptomatic thrombosis. Indications for anticoagulant therapy in patients with asymptomatic thrombosis were as follows: enlarging thrombus (E, thrombus >40 mm in diameter (S, thrombus involving the superior vena cava (C, and decreased blood flow (V.Results: Among 79 patients enrolled in this study, asymptomatic thrombosis was detected in 56 patients (70.9% by Doppler ultrasound imaging after the first course of Bev and there was no thrombus in 23 patients (29.1%. Of these 56 patients, 11 (19.6% received anticoagulant therapy with warfarin, including eight after the first course and three after follow-up imaging.

    Full Text Available Superficial skin bleeding can usually be stopped by applying short-time compression, unless the patient suffers from coagulation disorders or uses anticoagulant. Because of the anticoagulant component of leech saliva, a leech bite may cause long-time bleeding, which cannot be stopped via compression.

    Accidental poisoning with anticoagulant rodenticides is not uncommon in dogs, but few reports of the elimination kinetics and half-lives in this species have been published. Our objectives were to develop and validate a new method for the quantification of anticoagulant rodenticides in canine blood and faeces using reversed phase ultra-high performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) and apply the method on a case of anticoagulant rodenticide intoxication. Sample preparation was liquid-liquid extraction. Six anticoagulant rodenticides were separated using a UPLC ® BEH C 18 -column with a mobile phase consisting of 5 mM ammonium formate buffer pH 10.2 and methanol. MS/MS detection was performed with positive electrospray ionization and two multiple reaction monitoring transitions. The limits of quantification were set at the levels of the lowest calibrator (1.5-2.7 ng/mL or ng/g). The method was successfully applied to a case from a dog accidentally poisoned with anticoagulant rodenticide. Coumatetralyl and brodifacoum concentrations were determined from serial blood and faecal samples. A terminal half-life of at least 81 days for coumatetralyl in blood was estimated, which is longer than previous reported in other species. A slow elimination of brodifacoum from the faeces was found, with traces still detectable in the faeces at day 513. This study offers a new method of detection and quantification of six frequently used anticoagulant rodenticides in canine faeces. Such drugs might cause serious health effects and it is important to be able to detect these drugs, to initiate proper treatment. The very long elimination half-lives detected in our study is important to be aware of in assessment of anticoagulant rodenticide burden to the environment.

    Full Text Available Background: Anticoagulation patient self-testing (PST represents an alternative approach to warfarin monitoring by enabling patients to use coagulometers to test their international normalized ratio (INR values. PST offers several advantages that potentially improve warfarin management. Objective: To describe implementation and associated performance of a PST demonstration program at an Indian Health Service (IHS facility. Methods: A non-consecutive case series analysis of patients from a pharmacy-managed PST demonstration program was performed at an IHS facility in Oklahoma between July 2008 and February 2009.Results: Mean time in therapeutic range (TTR for the seven patients showed a small, absolute increase during the twelve weeks of PST compared to the twelve weeks prior to PST. Four of the seven patients had an increase in TTR during the twelve week course of PST compared to their baseline TTR. Three of four patients with increased TTR in the final eight week period of PST achieved a TTR of 100%. Of the three patients who experienced a decrease in TTR after initiating self-testing, two initially presented with a TTR of 100% prior to PST and one patient had a TTR of 100% for the final eight weeks of PST. The two patients not achieving a TTR of 100% during the twelve week PST period demonstrated an increase in TTR following the first four weeks of PST. Conclusion: Although anticoagulation guidelines now emphasize patient self-management (PSM only, optimal PST remains an integral process in PSM delivery. In the patients studied, the results of this analysis suggest that PST at the IHS facility provided a convenient, alternative method for management of chronic warfarin therapy for qualified patients. More than half of the patients demonstrated improvement in TTR. Although there is a learning curve immediately following PST initiation, the mean TTR for the entire PST period increased modestly when compared to the time period prior to PST.

  19. Is stopping of anticoagulant therapy really required in a minor dental surgery? - How about in an endodontic microsurgery?

    2013-08-01

    Full Text Available Nowadays, oral anticoagulants are commonly prescribed to numerous patients for preventing cardiovascular accident such as thromboembolism. An important side effect of anticoagulant is anti-hemostasis. In a major surgery, the oral anticoagulant therapy (OAT regimen must be changed before the surgery for proper post-operative bleeding control. However, in a minor dental surgery and endodontic surgery, the necessity for changing or discontinuing the OAT is open to debate. In this study, risks of the consequences were weighed and analyzed. In patients who stop the OAT, the occurrence of thromboembolic complication is rare but the result is fatal. In patients who continuing the OAT, post-operative bleeding can be controlled well with the local hemostatic measures. In the endodontic surgery, there are almost no studies about this issue. The intra-operative bleeding control is particularly important in the endodontic surgery because of its delicate and sensitive procedures such as inspection of resected root surface using dental microscope and retrograde filling. Further studies are necessary about this issue in the viewpoint of endodontic surgery.

    To summarize the available evidence on the issues in health economics related to oral anticoagulation for stroke prevention in atrial fibrillation (AF) in the US. A literature review was performed using PubMed, EMBASE, Cochrane Library, and International Pharmaceutical Abstracts, as well as the websites of professional organizations. The search was conducted according to a prespecified protocol, limiting articles to those published in English from 2001 to October 2012 and focused on the economics associated with AF and AF-related stroke in the US. Data from 27 studies were extracted and included in the review. Strokes in patients with AF are more debilitating and have higher recurrence rates and mortality compared with strokes unrelated to AF. However, data describing the long-term cost of AF-related stroke and stroke subtypes remain limited. The costs of major gastrointestinal (GI) bleeding and intracranial bleeding related to warfarin are significant, whereas the costs of the more frequent minor GI bleeding are relatively low. Overall, the cost-effectiveness of warfarin versus aspirin or no treatment in patients with at least 1 risk factor for stroke is well established. Economic evaluations based on results from randomized controlled clinical trials generally found that new anticoagulants were a cost-effective alternative to warfarin for stroke prevention in AF. However, these cost-effectiveness results are highly sensitive to how well optimal international normalized ratio control is maintained (within target of 2.0-3.0) for warfarin and the time horizon used for analysis. Time in therapeutic range for warfarin in routine clinical practice was lower than in clinical trials, as shown by previous studies. This review identified several areas of uncertainty regarding the economic benefit of anticoagulants. The generalizability of cost-effectiveness results of anticoagulant therapy in AF based on clinical trial data must be confirmed by comparative effectiveness

    Psychological distress might affect the international normalized ratio (INR), but effects might vary depending on oral anticoagulant (OAC) therapy. To investigate the association of psychological distress with INR and clotting factors of the extrinsic pathway in patients with and without OAC therapy. We studied 190 patients with a previous venous thromboembolism (VTE); 148 had discontinued OAC therapy and 42 had ongoing OAC therapy. To assess psychological distress, all patients completed validated questionnaires to measure symptoms of depression, anxiety, worrying, anger and hostility. INR, fibrinogen, factor (F)II:C, FV:C, FVII:C and FX:C were measured as part of outpatient thrombophilia work-up. In VTE patients without OAC therapy, the odds of a reduced INR (therapy, INR was unrelated to a negative affect; however, lower FVII:C related to anxiety and worrying as well as lower FX:C related to anger and hostility were observed in patients with OAC therapy compared with those without OAC therapy. Psychological distress was associated with a reduced INR in VTE patients without OAC therapy. The direction of the association between psychological distress and activity in some clotting factors of the extrinsic coagulation pathway might differ depending on whether VTE patients are under OAC therapy or not. © 2012 International Society on Thrombosis and Haemostasis.

    Thromboembolic disease (TED) is the leading cause of morbidity and mortality worldwide. The hallmark of oral long-term anticoagulant therapy has been the use of vitamin K antagonists, whose anticoagulant effect is exerted inhibiting vitamin K epoxide reductase. Warfarin and acenocoumarol are the most commonly used. In the last five years several new drugs for long term anticoagulation have been developed, which can inhibit single clotting factors with the purpose of improving drug therapeutic range and, ideally, minimizing bleeding risks. This review addresses the state of the art on the clinical use of inhibitors of activated factor X and thrombin.

    In young adults Stroke is a challenging condition and various tests are needed to diagnose and manage its underlying problems. Free floating thrombosis of internal carotid artery (FFT-ICA) is one of the rare problems among carotid artery diseases which can lead to stroke in adults. Owing to limited cases of FFT-ICA there is not a worldwide accepted consensus on management of FFT-ICA, but some recurrences after medical management have been reported in the literature. A-25-year old woman was referred to hospital with sudden onset aphasia and right sided hemiparesis. Carotid duplex ultrasonography showed an iso-echogenic thrombus ranged about 5×10mm partially attached to arterial wall of the right internal carotid artery. It was floating in accordance with the heartbeat. Anticoagulation therapy was initiated and subsequently she underwent an urgent operation. To explore the etiology of her problem, various lab tests were carried out; the results showed markedly elevated levels of lupus anticoagulant. She was discharged from hospital after an uneventful recovery showing gradual improvement of symptoms in follow-up visits. FFT-ICA is one of the scarce disorders of carotid artery. Less than 150 cases have been reported in the literature indicating its common occurrence in old men. Hence the etiology of this case (FFT in a young patient with high levels of lupus anticoagulant antibody) may be the first of its type. In this case we chose surgical treatment resulting in complete resolution of symptoms and non-recurrence within 6 month follow-up. Copyright © 2017 The Authors. Published by Elsevier Ltd..

    The definition of non-valvular atrial fibrillation (NVAF) is controversial. We aimed to assess the impact of valvular heart disease on stroke prevention strategies in NVAF patients. The RAMSES study was a multicenter and cross-sectional study conducted on NVAF patients (ClinicalTrials.gov identifier NCT02344901). The study population was divided into patients with significant valvular disease (SVD) and non-significant valvular disease (NSVD), whether they had at least one moderate valvular disease or not. Patients with a mechanical prosthetic valve and mitral stenosis were excluded. Baseline characteristics and oral anticoagulant (OAC) therapies were compared. In 5987 patients with NVAF, there were 3929 (66%) NSVD and 2058 (34%) SVD patients. The predominant valvular disease was mitral regurgitation (58.1%), followed by aortic regurgitation (24.1%) and aortic stenosis (17.8%). Patients with SVD had higher CHA 2 DS 2 VASc [3.0 (2.0; 4.0) vs. 4.0 (2.0; 5.0), p valvular heart disease with the predominance of mitral regurgitation. Patients with SVD were at greater risk of stroke and bleeding compared to patients with NSVD. Although patients with mitral regurgitation should be given more aggressive anticoagulant therapy due to their higher risk of stroke, they are undertreated compared to patients with aortic valve diseases.

    Long half life oral anticoagulants have shown a higher anticoagulation stability and a lower hemorragic risk than those of a short half life. We have compared therapeutic stability and hemorragic risk of acenocoumarol versus warfarin in 2 groups of patients on preventive anticoagulation because of atrial fibrilation (international normalised ratio [INR]: 2-3). Data on 120 patients treated with acenocoumarol and 120 on warfarin treatment who had started and continued treatment in our hospital for a minimum of a year was collected. The percentage of visits within the intended range of INR (2 to 3) was 65.5% with warfarin and 63.4% with acenocoumarol. Thirty percent of patients on warfarin had 75% or more of their controls within range, while for those treated with acenocoumarol this percentage was 22.5%. In the acenocoumarol group, 0.3 visits/patient/year presented an INR > or = 6 versus 0.07 in the warfarin group (p = 0.003). Patients treated with acenocoumarol show a higher risk of presenting with an INR > or = 6, but no statistically significant differences are observed in therapeutic stability.

  12. Discrepancies between Patients' Preferences and Educational Programs on Oral Anticoagulant Therapy: A Survey in Community Pharmacies and Hospital Consultations.

    Full Text Available Oral anticoagulation therapy is increasingly used for the prevention and treatment of thromboembolic complications in various clinical situations. Nowadays, education programs for patients treated with anticoagulants constitute an integrated component of their management. However, such programs are usually based on the healthcare providers' perceptions of what patients should know, rather than on patients' preferences.To investigate patients' viewpoints on educational needs and preferred modalities of information delivery.We conducted an observational study based on a self-administered questionnaire. To explore several profiles of patients, the study was designed for enrolling patients in two settings: during outpatient consultations in a cardiology department (Saint Antoine Hospital, Paris, France and in community pharmacies throughout France.Of the 371 patients who completed the questionnaire, 187 (50.4% were recruited during an outpatient consultation and 184 (49.6% were recruited in community pharmacies. 84.1% of patients were receiving a vitamin K antagonist and 15.6% a direct oral anticoagulant. Patients ranked 16 of 21 (76.2% questionnaire items on information about their treatment as important or essential; information on adverse effects of treatment was the highest ranked domain (mean score 2.38, 95% CI 2.30-2.46. Pharmacists (1.69, 1.58-1.80, nurses (1.05, 0.95-1.16, and patient associations (0.36, 0.29-0.44, along with group sessions (0.85, 0.75-0.95, the internet (0.77, 0.67-0.88, and delivery of material at the patient's home (1.26, 1.14-1.38, were ranked poorly in terms of delivering educational material.This study revealed substantial discrepancies between patient preferences and current educational programs. These findings should be useful for tailoring future educational programs that are better adapted to patients, with a potential associated enhancement of their effectiveness.

    The aim of this study was to determine the opinion of internists on the management of anticoagulation and thromboembolism prophylaxis in complex clinical scenarios in which the risk-benefit ratio of surgery is narrow and to develop a consensus document on the use of drugs anticoagulant therapy in this patient group. To this end, we identified by consensus the clinical areas of greatest uncertainty, a survey was created with 20 scenarios laid out in 40 clinical questions, and we reviewed the specific literature. The survey was distributed among the internists of the Spanish Society of Internal Medicine (SEMI) and was completed by 290 of its members. The consensus process was implemented by changing the Delphi-RAND appropriateness method in an anonymous, double-round process that enabled an expert panel to identify the areas of agreement and uncertainty. In our case, we also added the survey results to the panel, a methodological innovation that helps provide additional information on the standard clinical practice. The result of the process is a set of 19 recommendations formulated by SEMI experts, which helps establish guidelines for action on anticoagulant therapy in complex scenarios (high risk or active haemorrhage, short life expectancy, coexistence of antiplatelet therapy or comorbidities such as kidney disease and liver disease), which are not uncommon in standard clinical practice.

    Pharmacogenetics-guided warfarin dosing is an alternative to standard clinical algorithms and new oral anticoagulants for patients with nonvalvular atrial fibrillation. However, clinical evidence for pharmacogenetics-guided warfarin dosing is limited to intermediary outcomes, and consequently, there is a lack of information on the cost-effectiveness of anticoagulation treatment options. A clinical trial simulation of S-warfarin was used to predict times within therapeutic range for different dosing algorithms. Relative risks of clinical events, obtained from a meta-analysis of trials linking times within therapeutic range with outcomes, served as inputs to an economic analysis. Neither dabigatran nor rivaroxaban were cost-effective options. Along the cost-effectiveness frontier, in relation to clinically dosed warfarin, pharmacogenetics-guided warfarin and apixaban had incremental cost-effectiveness ratios of £13,226 and £20,671 per quality-adjusted life year gained, respectively. On the basis of our simulations, apixaban appears to be the most cost-effective treatment.

    The diagnosis of the antiphospholipid syndrome (APS) is based on clinical and biological criteria including the persistent presence of antiphospholipid antibodies and thrombotic events or pregnancy morbidity. Heparins relayed by vitamin K antagonists (VKA) are the gold standard treatment for thrombosis. We report a 17-year-old man who presented with an initially seronegative antiphospholipid syndrome, in whom the diagnosis was late, only obtained after anticoagulation withdrawing, when a catastrophic antiphospholipid syndrome (CAPS) with cutaneous lesions and disseminated intravascular coagulation syndrome occurred. For personal convenience, this patient was initially treated with fondaparinux followed by a new oral anticoagulant (rivaroxaban) before to return to the conventional VKA treatment. The "seronegative" APS is a controversial concept reflecting the heterogeneity of antigenic targets for aPL. This diagnosis may be considered after a rigorous work-up, with the help of haemostasis laboratories testing new emerging aPL assays. In APS, the new anticoagulants represent an attractive option needing nevertheless prospective studies to evaluate their safety and efficacy. Lupus anticoagulant detection in patients treated by new oral anticoagulants is not easy by usually recommended coagulation tests. Copyright © 2014. Published by Elsevier SAS.

To evaluate treatment adherence and prevalence of CYP2C9 and VKORC1 gene mutations in patients with atrial fibrillation (AF and provide rationale of choice for oral anticoagulation therapy.Material and methods. Treatment adherence was evaluated in 137 AF patients (aged 35-85 years with quantitative estimation of drug therapy adherence along with compliance to medical support and lifestyle modifications. Among them 82 patients underwent polymerase chain reaction (PCR analysis of CYP2C9 and VKORC1 gene polymorphisms.Results. Patients receiving anticoagulation therapy are characterized by lower level of adherence compared to patients without anticoagulants (65.2±19.3% vs 68.5±19.1%; Wald-Wolfowitz; p<0.05. Considering all studied parameters men are less adherent than women (54.7±18.6% vs 60.6±16.7%; Kolmogorov-Smirnov; p<0.05. Patients receiving new oral anticoagulants (NOAC have better compliance compared with patients of warfarin group. Mutations in CYP2C9 gene were detected in 32.9%, VKORC1 – in 68.3%, and their combination – in 21.9% of study participants. Warfarin therapy may be potentially dangerous in such patients due to low adherence.Conclusion. Considering high prevalence of CYP2C9 and VKORC1 gene mutations treatment adherence should be estimated to optimize choice of anticoagulation therapy. NOAC treatment should be considered in patients with low adherence for prevention of thromboembolic complications.

    Currently, little evidence is available on the length and type of anticoagulation used for extended treatment for prevention of recurrent venous thromboembolism (VTE) in patients with unprovoked VTE who have completed initial oral anticoagulation therapy. To compare the efficacy and safety of available oral therapeutic options (aspirin, warfarin, direct oral anticoagulants (DOACs)) for extended thromboprophylaxis in adults with a first unprovoked VTE, to prevent VTE recurrence after completion of an acceptable initial oral anticoagulant treatment period, as defined in individual studies. For this review, the Cochrane Vascular Information Specialist (CIS) searched the Specialised Register (March 2017) as well as the Cochrane Central Register of Controlled Trials (CENTRAL; 2017, Issue 2). We also searched trials registries (March 2017) and reference lists of relevant articles. We included randomised controlled trials in which patients with a first, symptomatic, objectively confirmed, unprovoked VTE, who had been initially treated with anticoagulants, were randomised to extended prophylaxis (vitamin K antagonists (VKAs), antiplatelet agents, or DOACs) versus no prophylaxis or placebo. We also included trials that compared one type of extended prophylaxis versus another type of extended prophylaxis. Two review authors independently selected studies, assessed quality, and extracted data. We resolved disagreements by discussion. Six studies with a combined total of 3436 participants met the inclusion criteria. Five studies compared extended prophylaxis versus placebo: three compared warfarin versus placebo, and two compared aspirin versus placebo. One study compared one type of extended prophylaxis (rivaroxaban) versus another type of extended prophylaxis (aspirin). For extended prophylaxis versus placebo, we downgraded the quality of the evidence for recurrent VTE and all-cause mortality to moderate owing to concerns arising from risks of selection and performance bias

    To review various anticoagulation therapies and related laboratory monitoring issues, with a focus on factor X-related chromogenic assays. A case-based approach is used to review pertinent published literatures and product inserts of anticoagulation drugs and to look back on clinical use of factor X-related chromogenic assays. The number of anticoagulants available to clinicians has increased greatly in the past decade. Whether and how these anticoagulants should be monitored are areas of uncertainty for clinicians, which can lead to misuse of laboratory assays and suboptimal patient management. Factor X-related assays are of particular concern because of the similar and often confusing test names. Based on a common clinical case scenario and literature review regarding anticoagulant monitoring, an up-to-date discussion and review of the various factor X-related assays are provided, focusing on the differences in test designs and clinical utilities between the chromogenic anti-Xa and chromogenic factor X activity assays. Anticoagulation therapy and related laboratory monitoring are rapidly evolving areas of clinical practices. A good knowledge of relevant laboratory assays and their clinical applications is necessary to help optimize patient care.

    Full Text Available Data on the use of oral anticoagulation (OAC and antiplatelet therapy and the risk of bleeding and stroke amongst Asian patients with atrial fibrillation (AF are limited. We investigated the risks of bleeding and stroke with use of oral anticoagulation (OAC and antiplatelet therapy as mono- or combination therapy, in patients with AF from a Chinese nationwide cohort study.We studied a cohort of 10384 patients (57.2% men, age 67.8 ± 13.2 yrs between 1999 and 2010 from the National Health Insurance Research Database in Taiwan. Records of prescriptions were obtained during follow-up. The main outcome was a recurrent stroke during the follow-up period. Time-dependent Cox proportional hazards models were used for this analysis.We documented 1009 events for bleeding, as well as 224 hemorrhagic stroke and 1642 ischemic stroke events during a median 3.2 (interquartile range, 1.05-6.54 years' follow-up. Compared with warfarin users, patients with antiplatelet therapy had a lower risk of bleeding (adjusted relative risk [RR], 0.59, 95% confidence interval [CI], 0.49-0.71, p<0.001 whilst combination therapy had a non-statistically significant higher bleeding risk (RR, 1.33, 95%, 0.91-1.94, p = 0.20. Patients on antiplatelet monotherapy had a similar risk for ischemic stroke compared with OAC (RR 1.05, 95% CI, 0.89-1.25, p = 0.50, whilst those on combination therapy had a significantly higher risk (RR 1.90, 95% CI, 1.34-2.70, p<0.001.In a national representative cohort, antiplatelet therapy had no significant difference in ischemic stroke risk to warfarin. For bleeding, aspirin had a lower risk compared to warfarin. This may reflect poor anticoagulation control, highlighting important missed opportunities for improved stroke prevention, especially in countries where anticoagulation management is suboptimal.

    Oral anticoagulation therapy requires regular blood testing to ensure therapeutic levels are maintained and excessive bleeding/clotting is avoided. Technology-assisted self-testing and management is seen as one of the key areas in which quality of care can be improved whilst reducing costs. Nevertheless, levels of patient engagement in self-testing and management remain low. To date, little research emphasis has been placed on understanding the patients' perspectives for low engagement. The typical approach adopted by healthcare providers is to provide patient education programmes, with the expectation that individual patients will change their behaviour and adopt new self-care strategies. However, if levels of patient engagement are to be increased, healthcare providers must also develop a better understanding of how their clinical service provision is perceived by patients and make adaptations. To explore patient views, needs and expectations of an anticoagulation service and the self-testing and management services provided. Interviews were conducted with 17 patients who currently engage in international normalised ratio (INR) self-testing and management. Thematic coding and analysis were carried out on the interview transcripts. Four high-level themes emerged from interviews: (i) role of clinic, (ii) motivations for self-testing, (iii) managing INR and (iv) trust. The clinic was seen as adding value in terms of specifying testing frequency, dosage profiles and calibrating equipment. Prompt communication from clinic to patient was also valued, although more personalised/real-time communication would help avoid feelings of isolation. Patients felt more in control as self-tester/managers and often took decisions about treatment adjustments themselves. However, some also manipulated their own test results to avoid 'unnecessary' interventions. More personalised/real-time communication, pragmatic and collaborative patient-clinician partnerships and recognition of

  4. Maternal malaria induces a procoagulant and antifibrinolytic state that is embryotoxic but responsive to anticoagulant therapy.

    Directory of Open Access Journals (Sweden)

    John W Avery

    Full Text Available Low birth weight and fetal loss are commonly attributed to malaria in endemic areas, but the cellular and molecular mechanisms that underlie these poor birth outcomes are incompletely understood. Increasing evidence suggests that dysregulated hemostasis is important in malaria pathogenesis, but its role in placental malaria (PM, characterized by intervillous sequestration of Plasmodium falciparum, proinflammatory responses, and excessive fibrin deposition is not known. To address this question, markers of coagulation and fibrinolysis were assessed in placentae from malaria-exposed primigravid women. PM was associated with significantly elevated placental monocyte and proinflammatory marker levels, enhanced perivillous fibrin deposition, and increased markers of activated coagulation and suppressed fibrinolysis in placental plasma. Submicroscopic PM was not proinflammatory but tended to be procoagulant and antifibrinolytic. Birth weight trended downward in association with placental parasitemia and high fibrin score. To directly assess the importance of coagulation in malaria-induced compromise of pregnancy, Plasmodium chabaudi AS-infected pregnant C57BL/6 mice were treated with the anticoagulant, low molecular weight heparin. Treatment rescued pregnancy at midgestation, with substantially decreased rates of active abortion and reduced placental and embryonic hemorrhage and necrosis relative to untreated animals. Together, the results suggest that dysregulated hemostasis may represent a novel therapeutic target in malaria-compromised pregnancies.

    In treating peripheral arterial disease, a profound knowledge of antiplatelet and anticoagulative drug therapy is helpful to assure a positive clinical outcome and to anticipate and avoid complications. Side effects and drug interactions may have fatal consequences for the patient, so interventionalists should be aware of these risks and able to control them. Aspirin remains the first-line agent for antiplatelet monotherapy, with clopidogrel added where dual antiplatelet therapy is required. In case of suspected antiplatelet drug resistance, the dose of clopidogrel may be doubled; prasugrel or ticagrelor may be used alternatively. Glycoprotein IIb/IIIa inhibitors (abciximab or eptifibatide) may help in cases of hypercoagulability or acute embolic complications. Desmopressin, tranexamic acid, or platelet infusions may be used to decrease antiplatelet drug effects in case of bleeding. Intraprocedurally, anticoagulant therapy treatment with unfractionated heparin (UFH) still is the means of choice, although low molecular-weight heparins (LMWH) are suitable, particularly for postinterventional treatment. Adaption of LMWH dose is often required in renal insufficiency, which is frequently found in elderly patients. Protamine sulphate is an effective antagonist for UFH; however, this effect is less for LMWH. Newer antithrombotic drugs, such as direct thrombin inhibitors or factor X inhibitors, have limited importance in periprocedural treatment, with the exception of treating patients with heparin-induced thrombocytopenia (HIT). Nevertheless, knowing pharmacologic properties of the newer drugs facilitate correct bridging of patients treated with such drugs. This article provides a comprehensive overview of antiplatelet and anticoagulant drugs for use before, during, and after interventional radiological procedures.

    For critically ill patients, the use of regional citrate anticoagulation as part of continuous renal replacement therapy (CRRT) has become increasingly common in recent years. However, there are scarce data on the use of this technique in patients with burns. The aim of this study was to examine the effectiveness, feasibility and complications of regional citrate anticoagulation for CRRT in burn patients, as well as the effects on coagulation and the electrolyte and acid-base balance. This retrospective study included all patients who received renal replacement therapy with citrate anticoagulation to treat acute kidney injury (AKI) between January 1, 2004 and December 31, 2009 at the burn unit of St. Georg Hospital GmbH in Leipzig. During the examination period, 18 patients were treated using CRRT with regional citrate anticoagulation (CVVHDF in the pre-dilution mode). The median patient age was 64 years (49.5; 71), with a median TBSA of 42.5% (33.25; 52.5) and a median ABSI score of 10 (9; 10). The CRRT was initiated on a median of 6 days (4; 8.75) after admission to the hospital and continued for a median duration of 7 days (5; 8). The median dialysis dose was 38.2mlkgBW(-1)h(-1) (31.8; 42.1). The median effective filter operation time was 67h (46; 72). No relevant disorders associated with acid-base balance, electrolytes or coagulation occurred, and there were no bleeding complications. In terms of bleeding risk and electrolyte and acid-base balance, regional citrate anticoagulation may be considered to be an effective, safe and user-friendly procedure for patients with severe burns and AKI.

    2012-01-01

    The objective of this systematic review is to synthesize the best available evidence on the impact of pre-injury anticoagulation therapy in the older adult patient who experiences a traumatic brain injury. Trauma in the elderly remains one of the most challenging problems for healthcare providers in the 21 century. The most recent United States (U.S.) census estimates that by the year 2020 more than 52 million Americans will be age 65 years or older, and one million of those will live to be over 100 years of age. In the older adult population, classified as age 65 years or greater, the two leading causes of injury were reported as motor vehicle crashes (MVC) and falls. We have become increasingly aware of the unique physiologic changes in this population that make them more susceptible to succumb to traumatic injuries than their younger counterparts. This is especially true in the anticoagulated patient with a traumatic brain injury.Traumatic brain injury (TBI) is defined as an injury occurring when an external force traumatizes the brain. It may also be known as an intracranial or head injury. TBI is classified depending on the mechanism of injury (blunt or penetrating), severity, and location of the assault. Damage to the brain, skull, and/or scalp transpires. TBI is the leading cause of death and disability in the U.S, and persons of all ages, races, ethnicities, and incomes are affected. In the past five to ten years, trauma services have recorded an increase in major trauma admissions of patients age 65 years and older. In review of the literature to date, it is recognized that outcomes following moderate to severe TBI in older adults are poor, with high rates of significant disability and mortality reported. A recent Australian study reported that 28% of older adults died in the hospital following a TBI and in Finland adults aged 75 years and older had the highest rates of TBI related hospitalizations and death. According to a systematic review of European

    The management of AF represents a major challenge in patients with CLL, especially in elderly patients with multiple comorbidities who are representative of the majority of patients with CLL. This is especially complex in the case of ibrutinib. Many anticoagulants have potential for pharmacological interaction with ibrutinib, and ibrutinib itself has antiplatelet properties. Use of ibrutinib therapy in these patients mandates review and revision of the need for anticoagulation and best anticoagulant to use. Herein, we review the current knowledge of the metabolism of common anticoagulants and how they may interact with ibrutinib.

    To assess the effectiveness of anticoagulant therapy (ACT) for the treatment of patients with deep venous thrombosis (DVT) of the lower extremities. The study considered ultrasonic characteristics of lysis of the proximal part of thrombus: localization and nature of venous thrombosis, the length and diameter of the proximal floating part of the thrombus, and duration of the venous thrombosis. Depending on the ACT options patients were divided into 3 groups: Group 1 (18 patients) received rivaroxaban, group 2 (19 patients) received enoxaparin sodium with subsequent transition to warfarin, and 3 group (19 patietns) received enoxaparin sodium, followed by administration of rivaroxaban. Treatment with rivaroxaban was preferable over standard ACT with enoxaparin/warfarin with regards to the lysis of thrombus when duration of thrombosis did not exceed 10 days. In 10.5% of patients who received warfarin flotation of thrombi remained for 14 days; the length of the floating part of the thrombi did not exceed 3 cm. Such circumstances and inability to reach a therapeutic INR value required cava filter placement. Treatment with enoxaparin sodium followed by the administration of rivaroxaban was found to be the most efficient ACT regimen as there was no negative dynamics of ultrasound characteristics of lysis of thrombi at any duration of the disease.

    Full Text Available Although oral anticoagulant therapy (OAT is recommended for patients with atrial fibrillation (AF, it is widely underused among older patients, who are frequently prescribed antiplatelet therapy (APT instead. We assessed mortality and incidence of ischemic and hemorrhagic events according to prescription of OAT or APT in older medical in-patients with AF discharged from hospital. Stroke and bleeding risk were evaluated using the CHA2DS2-VASC (Congestive heart failure/ left ventricular dysfunction, Hypertension, Aged ≥75 years, Diabetes Mellitus, Stroke/transient ischemic attack/systemic embolism, Vascular Disease, Aged 65-74 years, Sex Category and HAS-BLED (Hypertension, Abnormal renal/liver function, Stroke, Bleeding history or predisposition, Labile international normalized ratio, Elderly, Drugs/alcohol concomitantly scores. Comorbidity, cognitive status and functional autonomy were assessed using standardized scales. Association of OAT and APT with overall mortality, ischemic stroke and bleeding events was evaluated through multivariate analysis and propensity score matching. During a mean follow-up period of 11 months 384 of the 962 patients discharged (mean age 82.9±6.6 years, 59.1% female died (39.9%, 66 had an ischemic stroke and 49 experienced a major bleeding event. Compared with APT, OAT was associated with reduced overall mortality after multivariate analysis [odds ratio (OR 0.62, confidence interval (CI: 0.46-0.83] and after propensity score matched analysis (OR 0.65, CI: 0.52-0.82, P=0.0004, with a not significant reduced incidence of total and fatal ischemic stroke, and without increase in total, intracranial, major and fatal bleedings. In a sample of older AF patients with poor health status, OAT was associated with reduced mortality, without evidence of a significant increase in major or fatal bleedings.

    Objective Unlike several other national health agencies, French health authorities recommended that the newer direct oral anticoagulant (DOAC) agents only be prescribed as second choice for the treatment of newly diagnosed non-valvular atrial fibrillation (NVAF), with vitamin K antagonists (VKA) remaining the first choice. We investigated the patterns of use of DOACs versus VKA in the treatment of NVAF in France over the first 5 years of DOAC availability. We also identified the changes in patient characteristics of those who initiated DOAC treatment over this time period. Methods Based on the French National Health Administrative Database, we constituted a population-based cohort of all patients who were newly treated for NVAF between January 2011 and December 2015. Trends in drug use were described as the percentage of patients initiating each drug at the time of treatment initiation. A multivariate analysis using logistic regression model was performed to identify independent sociodemographic and clinical predictors of initial anticoagulant choice. Results The cohort comprised 814 446 patients who had received a new anticoagulant treatment for NVAF. The proportion of patients using DOACs as initial anticoagulant therapy reached 54% 3 months after the Health Ministry approved the reimbursement of dabigatran for NVAF, and 61% by the end of 2015, versus VKA use. In the multivariate analysis, we found that DOAC initiators were younger and healthier overall than VKA initiators, and this tendency was reinforced over the 2011–2014 period. DOACs were more frequently prescribed by cardiologists in 2012 and after (adjusted OR in 2012: 2.47; 95% CI 2.40 to 2.54). Conclusion Despite recommendations from health authorities, DOACs have been rapidly and massively adopted as initial therapy for NVAF in France. Observational studies should account for the fact that patients selected to initiate DOAC treatment are healthier overall, as failure to do so may bias the risk

Recently, fondaparinux and edoxaban are being used as beneficial alternatives to UFH and VKA.Methods: We evaluated the clinical course of symptomatic deep vein thrombosis (DVT in patients who received the 3-month anticoagulation therapy with fondaparinux/edoxaban (Group A; n=40 in comparison with the findings from our previous experience of patients who received the fondaparinux/VKA combination (Group B; n=33.Results: In both Groups A and B, serum D-dimer was significantly improved after treatment (p<0.001. The thrombus volume assessed by quantitative ultrasound thrombosis (QUT score was significantly reduced in both groups (p<0.001. There was no difference in the proportion of patients who were normalized (ie, disappearance of DVT between the groups, although Group A had significantly more patients who were normalized or improved (ie, disappearance and reduction of DVT (p<0.001. No bleeding event was observed in either group. However, in one patient in Group B, worsening of DVT and development of symptomatic PE were observed.Conclusion: Fondaparinux/edoxaban therapy is as effective as fondaparinux/VKA. This treatment has the possible advantage in thrombus regression. This would be a beneficial therapeutic option for both patients and physicians.

    Full Text Available Antithrombotic therapy consisting of a dual anti-platelet therapy (DAPT and oral anti-coagulation (OAC with a vitamin k antagonist is often referred to as triple therapy. This combined anticoagulation is applied in patients undergoing coronary artery stent implantation while also having an indication for OAC. Triple therapy increases the risk for bleeding events compared to either DAPT or OAC alone and thereby might be associated with adverse outcomes. Clinical data on the frequency of bleeding events in patients on triple therapy from clinical trials derives from pre-selected patients and may differ from the real world patients. We report data on patient characteristics and bleeding incidence of patients dismissed on triple therapy from a single university hospital. Within the time span from January 2000 to December 2012, we identified a total of 213 patients undergoing PCI who were prescribed a triple therapy for at least 4 weeks (representing 0.86% of all patients treated. The usage of triple therapy significantly increased over the observed time period. The average CHA2DS2-VASc Score was 3.1 ± 1.1 with an average HAS-BLED score of 2.5 ± 0.86 representing a high-risk group for thromboembolic events as well as considerable risk for bleeding events. An on-treatment bleeding incidence of 9.4% was detected, with gastrointestinal and airway bleeding being the most frequent (5.1% and 1.4%, respectively. This is consistent with data from clinical trials and confirms the high risk of bleeding in patients on DAPT plus OAC. 29.0% of all patients receiving triple therapy had an indication for OAC other than non-valvular atrial fibrillation. This substantial patient group is underrepresented by clinical trials and needs further attention.

    Full Text Available BACKGROUND: Patients on warfarin therapy undergo invasive and expensive checks for the coagulability of their blood. No information on coagulation levels is currently available between two controls. METHODOLOGY: A method was developed to determine warfarin in oral fluid by HPLC and fluorimetric detection. The chromatographic separation was performed at room temperature on a C-18 reversed-phase column, 65% PBS and 35% methanol mobile phase, flow rate 0.7 mL/min, injection volume 25 µL, excitation wavelength 310 nm, emission wavelength 400 nm. FINDINGS: The method was free from interference and matrix effect, linear in the range 0.2-100 ng/mL, with a detection limit of 0.2 ng/mL. Its coefficient of variation was <3% for intra-day measurements and <5% for inter-day measurements. The average concentration of warfarin in the oral fluid of 50 patients was 2.5±1.6 ng/mL (range 0.8-7.6 ng/mL. Dosage was not correlated to INR (r = -0.03, p = 0.85 but positively correlated to warfarin concentration in the oral fluid (r = 0.39, p = 0.006. The correlation between warfarin concentration and pH in the oral fluid (r = 0.37, p = 0.009 confirmed the importance of pH in regulating the drug transfer from blood. A correlation between warfarin concentration in the oral fluid and INR was only found in samples with pH values ≥7.2 (r = 0.84, p = 0.004. CONCLUSIONS: Warfarin diffuses from blood to oral fluid. The method allows to measure its concentration in this matrix and to analyze correlations with INR and other parameters.

    Optimising filter life and performance efficiency in continuous renal replacement therapy has been a focus of considerable recent research. Larger high quality studies have predominantly focussed on optimal anticoagulation however CRRT is complex and filter life is also affected by vascular access, circuit and management factors. We performed a systematic search of the literature to identify and quantify the effect of vascular access, circuit and patient factors that affect filter life and presented the results as a meta-analysis. A systematic review and meta-analysis was performed by searching Pubmed (MEDLINE) and Ovid EMBASE libraries from inception to 29 th February 2016 for all studies with a comparator or independent variable relating to CRRT circuits and reporting filter life. Included studies documented filter life in hours with a comparator other than anti-coagulation intervention. All studies comparing anticoagulation interventions were searched for regression or hazard models pertaining to other sources of variation in filter life. Eight hundred nineteen abstracts were identified of which 364 were selected for full text analysis. 24 presented data on patient modifiers of circuit life, 14 on vascular access modifiers and 34 on circuit related factors. Risk of bias was high and findings are hypothesis generating. Ranking of vascular access site by filter longevity favours: tunnelled semi-permanent catheters, femoral, internal jugular and subclavian last. There is inconsistency in the difference reported between femoral and jugular catheters. Amongst published literature, modality of CRRT consistently favoured continuous veno-venous haemodiafiltration (CVVHD-F) with an associated 44% lower failure rate compared to CVVH. There was a trend favouring higher blood flow rates. There is insufficient data to determine advantages of haemofilter membranes. Patient factors associated with a statistically significant worsening of filter life included mechanical

    Existing algorithms account for ~50% of observed variance in warfarin dose requirements after including common polymorphisms. However, they do not perform as well in populations other than Caucasians, in part because some ethno-specific genetic variants are overlooked. The objective of the present study was to identify genetic polymorphisms that can explain variability in warfarin dose requirements among Caribbean Hispanics of Puerto Rico. Next-Generation Sequencing of candidate genes CYP2C9 and VKORC1 and genotyping by DMET® Plus Assay of cardiovascular patients were performed. We also aimed at characterizing the genomic structure and admixture pattern of this study cohort. Our study used the Extreme Discordant Phenotype approach to perform a case-control association analysis. The CYP2C9 variant rs2860905, which was found in all the major haplotypes occurring in the Puerto Rican population, showed stronger association with warfarin sensitivity (A; CYP2C9 rs1856908; ABCB1 c.IVS9-44A>G/ rs10276036; CES2 c.269-965A>G/ rs4783745) and non-genetic factors (i.e., hypertension, diabetes and age) showed better prediction of warfarin dose requirements than CYP2C9 * 2 and CYP2C9 * 3 combined (partial R 2 = 0.132 vs. 0.023 and 0.007, respectively, p Puerto Ricans in the study cohort showed a tri-hybrid admixture pattern, with a slightly higher than expected contribution of Native American ancestry (25%). The genomic diversity of Puerto Ricans is highlighted by the presence of four different major haplotype blocks in the CYP2C9 locus. Although, our findings need further replication, this study contributes to the field by identifying novel genetic variants that increase predictability of stable warfarin dosing among Caribbean Hispanics.

    PurposeThe purpose of this study was to compare the efficacy of percutaneous aspiration thrombectomy (PAT) followed by standard anticoagulant therapy, with anticoagulation therapy alone, for the treatment of acute proximal lower extremity deep vein thrombosis.MethodsIn this randomised, prospective study, 42 patients with acute proximal iliofemoral deep vein thrombosis documented via Doppler ultrasound examination, were separated into an interventional treatment group (16 males, 5 females, average age 51 years) and a medical treatment group (13 males, 8 females, average age 59 years). In the interventional group, PAT with large-lumen 9-F diameter catheterisation was applied, after initiation of standard anticoagulant therapy. Balloon angioplasty (n 19) and stent implementation (n: 14) were used to treat patients with residual stenosis (>50 %) after PAT. Prophylactic IVC filters were placed in two patients. The thrombus clearance status of the venous system was evaluated by venography. In both the medical and interventional groups, venous patency rates and clinical symptom scores were evaluated at months 1, 3, and 12 after treatment.ResultsDeep venous systems became totally cleared of thrombi in 12 patients treated with PAT. The venous patency rates in month 12 were 57.1 and 4.76 % in the interventional and medical treatment groups, respectively. A statistically significant improvement was observed in clinical symptom scores of the interventional group (PAT) with or without stenting (4.23 ± 0.51 before treatment; 0.81 ± 0.92 at month 12) compared with the medical treatment group (4.00 ± 0.63 before treatment; 2.43 ± 0.67 at month 12). During follow-up, four patients in the medical treatment and one in the interventional group developed pulmonary embolisms.ConclusionsFor treatment of acute deep vein thrombosis, PAT with or without stenting is superior to anticoagulant therapy alone in terms of both ensuring venous patency and improving clinical

    Highlights: • Dual-energy CT can provide morphological and functional lung images in the same examination. • The subsequent dual-energy CT demonstrates the increased whole lung perfused blood volume (V{sub 120}) despite the residual intrapulmonary clots after treatment in one examination. • The increased whole lung perfusion (V{sub 120}) and a decreased low perfusion volume (V{sub 5}) result in the improvement in the low perfusion rate (%V{sub 5}) in the patients with acute pulmonary embolism after treatment. - Abstract: Objectives: Factors affecting the improvement in the lung perfused blood volume (LPBV) were evaluated based on the presence of intrapulmonary clots (IPCs) after anti-coagulation therapy using 64-slice dual-energy CT. Materials and methods: 96 patients exhibiting venous thromboembolism underwent initial and repeated LPBV examinations between December 2008 and July 2014. Fifteen patients were excluded due to pulmonary comorbidities, and a total of 81 patients were included in this study. Acute pulmonary embolism (PE) was diagnosed in 46 of the patients (56.7%). LPBV images were three-dimensionally reconstructed with two threshold ranges: 1–120 HU (V{sub 120}) and 1–5 HU (V{sub 5}), and the relative value of V{sub 5} per V{sub 120} expressed as %V{sub 5}. These values were subsequently compared with indicators of the severity of PE, such as the D-dimer level, heart rate and CT measurements. This study was approved by the local ethics committee. Results: In patients with IPCs, the D-dimer, V{sub 5} and %V{sub 5}values were significantly larger (p ≤ 0.01) in the initial LPBV, although these differences disappeared in subsequent LPBV after treatment. The right ventricular (RV) diameter, RV/left ventricular (RV/LV) diameter ratio and %V{sub 5} values were also significantly reduced, whereas the V{sub 5} value did not significantly decrease (p = 0.07), but V{sub 120} value significantly increased (p < 0.001) after treatment. However, in

    Full Text Available Objective: Novel oral anticoagulants (NOACs are increasingly being preferred by clinicians (and patients because they have a wide therapeutic window and therefore do not require monitoring of anticoagulant effect. Herein, we describe the unfortunate case of a patient who had fatal consequences as a result of switching from warfarin to rivaroxaban. Case Summary: A 90-year-old Caucasian woman, with atrial fibrillation on chronic anticoagulation with warfarin, was admitted to the hospital for pneumonia. She was treated with levofloxacin. In the same admission, her warfarin was switched to rivaroxaban. On Day 3 after the switch, her INR was found to be 6, and she developed a cervical epidural hematoma from C2 to C7. She ultimately developed respiratory arrest, was put on comfort care and died. Discussion: Rivaroxaban and warfarin are known to have a synergistic anticoagulant effect, usually seen shortly after switching. Antibiotics also increase the effects of warfarin by the inhibition of metabolizing isoenzymes. It is hypothesized that these two effects led to the fatal cervical spinal hematoma. Conclusion: The convenience of a wide therapeutic window and no requirement of laboratory monitoring makes the NOACs a desirable option for anticoagulation. However, there is lack of data and recommendations on how to transition patients from Warfarin to NOACs or even how to transition from one NOAC to another. Care should be taken to ensure continuous monitoring of anticoagulation when stopping, interrupting or switching between NOACS to avoid the possibility of fatal bleeding and strokes.

    Heparin is one of the most frequently used anticoagulants. It is easy to use, but can be associated with life-threatening side effects. One of these is heparin-induced thrombocytopenia syndrome (HITS), which develops in about 3-5% of patients exposed to heparin and is associated with thrombosis in 1% of cases. We report here the successful treatment of five patients with HITS who were treated with alternative anticoagulants namely danaparoid or hirudin. The median time between their exposure to heparin and onset of symptoms and or signs was 10.2 days (range 7-14 days). Platelet counts decreased to a mean of 38.4 x 10(9) \\/l (12-82 x 10(9)\\/l). All five patients had evidence of thrombosis; four patients had clinical and radiological evidence of pulmonary emboli, one patient had confirmed deep vein thrombosis (DVT) and one patient had extensive skin necrosis of the thighs and abdomen. Platelet aggregation test were positive in two patients, inconclusive in one patient and negative in two patients. Two patients were anticoagulated with danaparoid and three with hirudin until their platelet counts returned to normal between 4 and 14 days (average 6 days) following the recognition of the syndrome. Our patients had significant morbidity, but no mortality. Immediate withdrawal of heparin is of paramount importance and introduction of alternative anticoagulant is necessary in the presence of thrombosis.

    Anticoagulant rodenticides are widely used for rodent control around the world. A rapid and sensitive method was developed and validated for the simultaneous determination of 13 anticoagulant rodenticides (coumafuryl, pindone, valone, warfarin, coumatetralyl, coumachlor, diphacinone, dicumarol, chlorophacinone, bromadiolone, difenacoum, flocoumafen, and brodifacoum) in human blood by liquid chromatography-tandem mass spectrometry. After liquid-liquid extraction, the anticoagulant rodenticides were separated on an Eclipse Plus C18 column. Linearities were observed for each analyte in blood ranging from 0.5 to 50 ng/mL, with correlation coefficients over 0.99. The limits of detection ranged from 0.01 to 0.2 ng/mL, and the limits of quantification were 0.5 ng/mL for all analytes. The intraday and interday precisions were <15%, and accuracies ranged from 80.3% to 111.0%. This validated method with high sensitivity has been applied in three anticoagulant rodenticide poisoning cases and has been used successfully in monitoring blood concentrations for months. © 2017 American Academy of Forensic Sciences.

    Full Text Available Jane Hoover-PlowJoseph J Jacobs Center for Thrombosis and Vascular Biology, Departments of Cardiovascular Medicine and Molecular Cardiology, Lerner Research Institute Cleveland Clinic, Ohio, USAAbstract: The coagulation and fibrinolytic pathways regulate hemostasis and thrombosis, and an imbalance in these pathways may result in pathologic hemophilia or thrombosis. The plasminogen system is the primary proteolytic pathway for fibrinolysis, but also has important proteolytic functions in cell migration, extracellular matrix degradation, metalloproteinase activation, and hormone processing. Several studies have demonstrated plasmin cleavage and inactivation of several coagulation factors, suggesting plasmin may be not only be the primary fibrinolytic enzyme, but may have anticoagulant properties as well. The objective of this review is to examine both in vitro and in vivo evidence for plasmin inactivation of coagulation, and to consider whether plasmin may act as a physiological regulator of coagulation. While several studies have demonstrated strong evidence for plasmin cleavage and inactivation of coagulation factors FV, FVIII, FIX, and FX in vitro, in vivo evidence is lacking for a physiologic role for plasmin as an anticoagulant. However, inactivation of coagulation factors by plasmin may be useful as a localized anticoagulant therapy or as a combined thrombolytic and anticoagulant therapy.Keywords: thrombosis, anticoagulant, cardiovascular disease, plasminogen’s protease, blood

    Prompt recanalization of the vein containing the thrombus is an important goal during the initial treatment of DVT, and risk factors for delayed recanalization in patients with deep vein thrombosis (DVT) in the lower extremities need to be determined. A total of 174 patients with DVT in lower extremities were recruited from June 2014 to March 2015 at our hospital. Duplex ultrasound scanning was conducted for all patients at 1 and 6 months after baseline evaluation. We divided the patients into recanalization and non-recanalization groups and analyzed risk factors for delayed recanalization. The univariate analysis revealed that an oral anticoagulant time of less than 3 months and venous thrombus location were risk factors for delayed recanalization (P0.05). The multivariate analysis showed that patients with an anticoagulant time of less than 3 months had a lower incidence of recanalization than those with an anticoagulant time of more than 3 months (OR=2.358, Pvenous thrombus location are independent risk factors for delayed recanalization of DVT in the lower extremities.

    This study examined the prevalence of risk factors for urological stone surgery and their possible influence on outcome and complications following ureteroscopy (URS). The Clinical Research Office of the Endourological Society Ureteroscopy Global Study collected prospective data on consecutive patients with urinary stones treated with URS at centers around the world for 1 year. The prevalence of common comorbidities and anticoagulation therapy and their relationship with complications and age were examined. Of 11,719 patients, 2,989 patients (25.8%) had cardiovascular disease, including 22.6% with hypertension, and 1,266 patients (10.9%) had diabetes mellitus. Approximately six percent of patients were receiving oral anticoagulation therapy, including aspirin (3.7%) and clopidogrel (0.8%). The prevalence of hypertension and diabetes mellitus and the proportion of patients receiving anticoagulant medication and/or antidiabetes treatment increased with age. Elderly were more likely to develop a postoperative complication when they had diabetes, a cardiovascular disease or received anticoagulation therapy. Post-operative bleeding was higher in patients receiving anticoagulants than those not receiving them (1.1 vs. 0.4%; p < 0.01). Patients with risk factors for stone formation had more complications than those without (4.9 vs. 3.0%, p < 0.001). This is the first study confirming in a global population that URS can effectively and safely be performed in a population with high comorbidity. The risk of a complication was highest among elderly patients presenting with comorbidities.

    It is suggested that in young adults the Ross procedure results in better late patient survival compared with mechanical prosthesis implantation. We performed a propensity score-matched study that assessed late survival in young adult patients after a Ross procedure versus that after mechanical aortic valve replacement with optimal self-management anticoagulation therapy. We selected 918 Ross patients and 406 mechanical valve patients 18 to 60 years of age without dissection, aneurysm, or mitral valve replacement who survived an elective procedure (1994 to 2008). With the use of propensity score matching, late survival was compared between the 2 groups. Two hundred fifty-three patients with a mechanical valve (mean follow-up, 6.3 years) could be propensity matched to a Ross patient (mean follow-up, 5.1 years). Mean age of the matched cohort was 47.3 years in the Ross procedure group and 48.0 years in the mechanical valve group (P=0.17); the ratio of male to female patients was 3.2 in the Ross procedure group and 2.7 in the mechanical valve group (P=0.46). Linearized all-cause mortality rate was 0.53% per patient-year in the Ross procedure group compared with 0.30% per patient-year in the mechanical valve group (matched hazard ratio, 1.86; 95% confidence interval, 0.58 to 5.91; P=0.32). Late survival was comparable to that of the general German population. In comparable patients, there is no late survival difference in the first postoperative decade between the Ross procedure and mechanical aortic valve implantation with optimal anticoagulation self-management. Survival in these selected young adult patients closely resembles that of the general population, possibly as a result of highly specialized anticoagulation self-management, better timing of surgery, and improved patient selection in recent years.

    To clarify pharmacokinetic-pharmacodynamic (PK-PD) factors associated with the over-anticoagulation response in Asians during warfarin induction therapy, population PK-PD analyses were conducted in an attempt to predict the time-courses of the plasma S-warfarin concentration, Cp(S), and coagulation and anti-coagulation (INR) responses. In 99 Chinese patients we analyzed the relationships between dose and Cp(S) to estimate the clearance of S-warfarin, CL(S), and that between Cp(S) and the normal prothrombin concentration (NPT) as a coagulation marker for estimation of IC50. We also analyzed the non-linear relationship between NPT inhibition and the increase in INR to derive the non-linear index λ. Population analyses accurately predicted the time-courses of Cp(S), NPT and INR. Multivariate analysis showed that CYP2C9*3 mutation and body surface area were predictors of CL(S), that VKORC1 and CYP4F2 polymorphisms were predictors of IC50, and that baseline NPT was a predictor of λ. CL(S) and λ were significantly lower in patients with INR≥4 than in those with INR<4 (190 mL/h vs 265 mL/h, P<0.01 and 3.2 vs 3.7, P<0.01, respectively). Finally, logistic regression analysis revealed that CL(S), ALT and hypertension contributed significantly to INR≥4. All these results indicate that factors associated with the reduced metabolic activity of warfarin represented by CL(S), might be critical determinants of the over-anticoagulation response during warfarin initiation in Asians.

    Older adults are at substantial risk for cardiovascular disorders that may require anticoagulation therapy. Those on warfarin therapy report dissatisfaction and reduced quality of life (QOL) resulting from the treatment. Advances in the area of mobile health (mHealth) technology have resulted in the design and development of new patient-centric models for the provision of personalized health care services to improve care delivery. However, there is a paucity of research examining the effectiveness of mHealth tools on knowledge, attitudes, and patient satisfaction with treatment, as well as self-management, adherence to therapy, and QOL in older adults with chronic illness conditions requiring long-term warfarin therapy. The objective of the study was to explore the attitudes and preferences of older adults on warfarin therapy regarding the use of mHealth technology and health games to gain skills for self-management. We conducted group and individual interviews with patients (60 years or older) on warfarin therapy at two anticoagulation clinics affiliated with an academic medical center. We held 4 group and 2 individual interviews, resulting in 11 patient participants and 2 family caregiver participants. We used structured questions on three topic areas including medication self-management strategies, mHealth technology use, and health games for exercise. We demonstrated some commercial health apps related to medication management, vitamin K content of food, and a videogame for balance exercise. Discussions were audiotaped and transcribed verbatim. Common themes were drawn using content analysis. The participants reported awareness of the importance of staying on schedule with warfarin therapy. They also acknowledged that negative experiences of friends or family members who were taking warfarin influenced their desire to keep on schedule with warfarin therapy. In addition, the participants expressed that the use of mHealth technology may be helpful for medication

    Oral anticoagulation therapy is recommended for the prevention of recurrent ischemic stroke in patients with atrial fibrillation (AF). Current guidelines do not provide evidence-based recommendations on optimal time-point to start anticoagulation therapy after an acute ischemic stroke. Non-vitamin K antagonist oral anticoagulants (NOACs) may offer advantages compared to warfarin because of faster and more predictable onset of action and potentially a lower risk of intracerebral haemorrhage also in the acute phase after an ischemic stroke. The TIMING study aims to establish the efficacy and safety of early vs delayed initiation of NOACs in patients with acute ischemic stroke and AF. The TIMING study is a national, investigator-led, registry-based, multicentre, open-label, randomised controlled study. The Swedish Stroke Register is used for enrolment, randomisation and follow-up of 3000 patients, who are randomised (1:1) within 72 h from ischemic stroke onset to either early (≤ 4 days) or delayed (≥ 5-10 days) start of NOAC therapy. The primary outcome is the composite of recurrent ischemic stroke, symptomatic intracerebral haemorrhage, or all-cause mortality within 90 days after randomisation. Secondary outcomes include: individual components of the primary outcome at 90 and 365 days; major haemorrhagic events; functional outcome by the modified Rankin Scale at 90 days; and health economics. In an optional biomarker sub-study, blood samples will be collected after randomisation from approximately half of the patients for central analysis of cardiovascular biomarkers after study completion. The study is funded by the Swedish Medical Research Council. Enrolment of patients started in April 2017. The TIMING study addresses the ongoing clinical dilemma of when to start NOAC after an acute ischemic stroke in patients with AF. By the inclusion of a randomisation module within the Swedish Stroke Register, the advantages of a prospective randomised study design

    Bleeding complications are a serious adverse effect of medications that prevent abnormal blood clotting. To facilitate epidemiologic investigations of bleeding complications, we developed and validated an automated database case definition for bleeding-related hospitalizations. The case definition utilized information from an in-progress retrospective cohort study of warfarin-related bleeding in Tennessee Medicaid enrollees 30 years of age or older. It identified inpatient stays during the study period of January 1990 to December 2005 with diagnoses and/or procedures that indicated a current episode of bleeding. The definition was validated by medical record review for a sample of 236 hospitalizations. We reviewed 186 hospitalizations that had medical records with sufficient information for adjudication. Of these, 165 (89%, 95%CI: 83-92%) were clinically confirmed bleeding-related hospitalizations. An additional 19 hospitalizations (10%, 7-15%) were adjudicated as possibly bleeding-related. Of the 165 clinically confirmed bleeding-related hospitalizations, the automated database and clinical definitions had concordant anatomical sites (gastrointestinal, cerebral, genitourinary, other) for 163 (99%, 96-100%). For those hospitalizations with sufficient information to distinguish between upper/lower gastrointestinal bleeding, the concordance was 89% (76-96%) for upper gastrointestinal sites and 91% (77-97%) for lower gastrointestinal sites. A case definition for bleeding-related hospitalizations suitable for automated databases had a positive predictive value of between 89% and 99% and could distinguish specific bleeding sites.

    The period of anticoagulation of a first episode of idiopathic venous thromboembolism has been 6 months. It is unclear if such patients would benefit from longer treatment, as there appears to be an increased risk of recurrence after anticoagulation is stopped. In a randomized prospective study of 64 patients admitted to King Hussein Medical city, Amman, Jordan, who developed a first episode of venous thromboembolism, 32 patients were given warfarin for 24-months, while 32 patients stopped anticoagulation after completion of 6-months of therapy. Our goal was to determine the effects of extended anticoagulation on rates of recurrence of symptomatic venous thromboembolism and bleeding. The patients were followed for 12-months after stopping anticoagulation. After 24-months, 7 of the 32 patients (21%) who had standard anticoagulation for 6-months had a recurrent episode of thromboembolism compared to one of the 32 patients who received anticoagulation for 24 months (3%). Extended warfarin therapy for 24-months has resulted in an absolute risk reduction of 0.1% (p<0.05). This translates into 8 patients having to be treated for 24-months to avoid one recurrence without increasing the risk of major bleeding. Two patients in each group (6%) had major nonfatal bleeding, all 4 bleeding episodes occurring within the first 3-months of anticoagulation. After 36-months of follow up, the recurrence rate of extended warfarin therapy was only 3 patients (9%), which is a 43% relative reduction in recurrence of thromboembolism compared to standard therapy for 6-months. Patients with first episodes of idiopathic venous thromboembolism have an increased risk of recurrent venous thromboembolism and should be treated with oral anticoagulants for longer than 6-months, probably 24-months.

    2014-01-01

    Full Text Available Introduction Rhabdomyolysis is a rare, but serious and potentially fatal adverse reaction of the statin application that may be developed in any time of therapy. It is characterized by massive destruction of muscles associated with the large increase of creatine kinase (CK leading to myoglobinuria and potential acute renal failure. Combined statin-fibrate therapy increases the risk of rhabdomyolysis, especially in elderly and diabetic patients. Case report An 81-year-old male was admitted to Coronary Care Unit of the Emergency Center, Clinical Center of Serbia (CCS with the clinical picture and electrocardiogram of the acute anterior wall myocardial infarction complicated with pulmonary edema. Laboratory tests on admission showed higher elevated values of serum creatinine 179 μmol/L and BUN 9.2 mmol/L (eGFR 32 mL/min/1.73m2, CK 309 U/L (on day 2: 3476 U/L and mixed hyperlipidemia (total cholesterol 10.3 mmol/L, HDL 2.26 mmol/L, TG 4.85 mmol/L. The patient was treated with thrombolysis medication therapy (Alteplase, anticoagulant and dual antiplatelet therapy, diuretics, organic nitrates, angiotensin-converting enzyme (ACE inhibitors, antibiotics, and proton pump inhibitors. During seven days, his therapy included combined pravastatin 20 mg and fenofibrate (160 mg, which was discontinued due to pains and weakness of muscles and significantly elevated CC to 7080 U/L (upper limit 200 U/L, but no significant deterioration of renal function was observed. Discontinuation of therapy resulted in CC level normalization and improvement of clinical condition. Conclusion Combined statin and fibrate therapy requires strict clinical control and monitoring of CK i transaminases. Four-time or higher increase of CK requires discontinuation of therapy. In addition, patients are advised to report immediately any pains in muscles, sensibility, weakness or cramps.

    Purpose: Patients (pts.) with atrial fibrillation (AF) and atrial thrombi are known to have an increased risk for cerebral embolism. However, little is known about the clinical course of atrial thrombi and the incidence of cerebral embolism in those patients during anticoagulation therapy. The high sensitivity of MR imaging (MRI) including diffusion-weighted imaging (DWI) suggests that this technique could provide an improved estimate of cerebral embolism associated with the presence of left atrial thrombi. The aims of this prospective study were to evaluate (1) the prevalence of clinically silent and apparent cerebral embolism in pts. with newly diagnosed AF and atrial thrombi using MRI/DWI, (2) the long-term fate of atrial thrombi under continued anticoagulation therapy and (3) the incidence of cerebral embolism during a follow-up period of 12 months with continuous anticoagulation therapy. Materials and methods: The study group consisted of 32 pts. with (1) newly diagnosed AF and evidence of left atrial (LA) thrombi detected by TEE and (2) a new start of anticoagulation therapy [International Normalized Ratio (INR) 2.0-3.0]. 19 pts. with (1) newly diagnosed AF and no evidence of atrial thrombi and (2) an equivalent anticoagulation regimen served as the control group. In both groups (a) MRI/DWI studies of the brain (weeks 0, 4, 8, 12, 20, 28, 36, 44, and 52), (b) transesophageal echocardiographic studies (TEE) for assessment of LA-Thrombi (weeks 0 and 52) and (c) clinical neurological assessments (weeks 0, 20 and 52) were performed. Results: In the study group (AF and LA-Thrombi) 11 out of 32 pts. (34%) displayed signs of acute (n=8) or chronic (n=3) cerebral embolism in the initial MRI studies. In 4 out of 32 pts.(13%), MRI/DWI depicted new or additional cerebral emboli (n=12) during the follow-up period despite continuous anticoagulation therapy. 2 (n=2/4; 50%) of these patients had clinically apparent neurological deficits. In the control group 1 out of 19 pts

    Full Text Available Regional anticoagulation with citrate is an alternative to heparin in continuous renal replacement therapies, which may prolong circuit lifetime and decrease hemorrhagic complications. A retrospective comparative cohort study based on a prospective observational registry was conducted including critically ill children undergoing CRRT. Efficacy, measured as circuit survival, and secondary effects of heparin and citrate were compared. 12 patients on CRRT with citrate anticoagulation and 24 patients with heparin anticoagulation were analyzed. Median citrate dose was 2.6 mmol/L. Median calcium dose was 0.16 mEq/kg/h. Median heparin dose was 15 UI/kg/h. Median circuit survival was 48 hours with citrate and 31 hours with heparin (P=0.028. 66.6% of patients treated with citrate developed mild metabolic alkalosis, which was directly related to citrate dose. There were no cases of citrate intoxication: median total calcium/ionic calcium index (CaT/I of 2.16 and a maximum CaT/I of 2.33, without metabolic acidosis. In the citrate group, 45.5% of patients developed hypochloremia and 27.3% hypomagnesemia. In the heparin group, 27.8% developed hypophosphatemia. Three patients were moved from heparin to citrate to control postoperatory bleeding. In conclusion citrate is a safe and effective anticoagulation method for CRRT in children and it achieves longer circuit survival than heparin.

    Full Text Available Abstract Background Atrial fibrillation (AF patients with a high risk of stroke are recommended anticoagulation with warfarin. However, the benefit of warfarin is dependent upon time spent within the target therapeutic range (TTR of their international normalised ratio (INR (2.0 to 3.0. AF patients possess limited knowledge of their disease and warfarin treatment and this can impact on INR control. Education can improve patients' understanding of warfarin therapy and factors which affect INR control. Methods/Design Randomised controlled trial of an intensive educational intervention will consist of group sessions (between 2-8 patients containing standardised information about the risks and benefits associated with OAC therapy, lifestyle interactions and the importance of monitoring and control of their International Normalised Ratio (INR. Information will be presented within an 'expert-patient' focussed DVD, revised educational booklet and patient worksheets. 200 warfarin-naïve patients who are eligible for warfarin will be randomised to either the intervention or usual care groups. All patients must have ECG-documented AF and be eligible for warfarin (according to the NICE AF guidelines.

    Full Text Available PURPOSE: To conduct a systematized review of the literature about the main local hemostatic measures to control postoperative bleeding in anticoagulated patients. METHODS: A systematized review of literature was performed in the electronic database Medline (PubMed without restriction of the publication date. The eligibility criteria were studies involving maintenance of the anticoagulant therapy, prospective studies, retrospective studies, randomized clinical trials, controlled clinical studies, comparative studies, multicentric studies or case-control studies. Studies discontinuing anticoagulant therapy, case reports, literature reviews, in vitro studies, animal experiments and articles written in language not compatible with the search strategy adopted in this work were excluded. RESULTS: Twenty-four articles that met the adopted eligibility criteria were selected, enrolling 3891 subjects under anticoagulant therapy. A total of 171 cases of hemorrhage was observed. Tranexamic acid was the main local hemostatic measure used to controlling of postoperative bleeding. CONCLUSION: The local hemostatic measures proved to be effective according to previously published studies. Nevertheless, further clinical studies should be conducted to confirm this effectiveness.

    Full Text Available Life-threatening bleeding in anticoagulation with Warfarin is an emergency challenging issue. Several approaches are available to treat bleeding in either over-anticoagulation or propeanticoagulation, including vitamin K, fresh frozen plasma and prothrombin complex concentrates (PCC administration. In coexisting trauma-induced bleeding and anticoagulation, reversal of anticoagulation must be a rapid and highly effective procedure. Furthermore the appropriate treatment must be directly available in each shock rooms to guarantee the rapid management of the emergency. PCC require a simple storage, rapid accessibility, fast administration procedures and high effectiveness. Here we report the utility of PCC in management of a craniofacial trauma in proper-anticoagulation.

    2001-07-01

    Generalized osteoporosis is a result of different causes and pathogenic mechanisms, which often combine forces to become clinically relevant. Among the different exogenic factors, drugs play an important role, frequently in connection with other factors such as immobilization or pregnancy. It has been suggested that anticoagulation therapy with heparins or coumarins may induce osteoporotic changes or enhance the development of osteoporosis for other reasons. According to in vitro experiments, preclinical trials, and clinical investigations, it seems reasonable to assume that heparins induce increased bone loss in a time- and dose-related manner. Low-molecular-weight heparins most likely have less effect on bone turnover when compared to unfractionated heparin. Oral anticoagulation therapy with vitamin K-antagonists is believed to have a weak effect on induction of osteoporosis, but clinical studies are contradictory. In spite of the fact that a relevant effect of these drugs on the induction of osteoporosis is questionable, it must be taken into consideration that anticoagulant drugs may enhance the negative effects on bone density of other risk factors capable of inducing osteoporosis such as immobilization, pregnancy, or endocrinological disorders.

    The prophylactic efficacy of long-term oral anticoagulant treatment (OAT) has been demonstrated in a number of clinical conditions with increased tendency to thromboembolism, and the number of individuals subjected to OAT in the industrialised world has increased substantially in recent years. Since this therapy requires considerable resources from both the health care system and the patients, the feasibility of patients' self-monitoring and self-management of OAT has been investigated (1,2,3). The anticipated advantages of this approach include improved convenience and compliance for the patient, who may increase his apprehension for managing the treatment. In addition, self-testing allows for more frequent control compared to the conventional out-patient approach. Importantly, a prerequisite for conceiving a safe and operational concept for patient self-management (PSM) is the availability of a portable INR monitoring system with an accuracy, precision, reproducibility, and long-term reliability comparable to standard coagulometric equipment. The purpose of the present study was to evaluate the feasibility of a commercially available INR-monitor. CoaguChek, for patient self-testing, through a step-wise investigation of the performance characteristics of the equipment in the laboratory, in command of the patient, and during self-testing and self-adjustment of treatment at home. Laboratory INR values were used as reference.

    Full Text Available Regional citrate anti-coagulation for continuous renal replacement therapy chelates calcium to produce the anti- coagulation effect. We hypothesise that a calcium-free replacement solution will require less citrate and produce fewer metabolic side effects. Fifty patients, in a Medical Intensive Care Unit of a tertiary teaching hospital (25 in each group, received continuous venovenous hemofiltration using either calcium-containing or calcium-free replacement solutions. Both groups had no significant differences in filter life, metabolic alkalosis, hypernatremia, hypocalcemia, and hypercalcemia. However, patients using calcium-containing solution developed metabolic alkalosis earlier, compared to patients using calcium-free solution (mean 24.6 hours,CI 0.8-48.4 vs. 37.2 hours, CI 9.4-65, P = 0.020. When calcium-containing replacement solution was used, more citrate was required (mean 280ml/h, CI 227.2-332.8 vs. 265ml/h, CI 203.4-326.6, P = 0.069, but less calcium was infused (mean 21.2 ml/h, CI 1.2-21.2 vs 51.6ml/h, CI 26.8-76.4, P ≤ 0.0001.

    We hypothesized that intermittent anticoagulation based on daily rhythm monitoring using the novel oral anticoagulants (NOACs) is feasible and safe among patients with paroxysmal atrial fibrillation (AF). Patients with paroxysmal AF and ≥1 risk factors for stroke were randomized to either intermittent or continuous anticoagulation. Those in the intermittent group were instructed to transmit a daily ECG using an iPhone-based rhythm monitoring device. If AF was detected, patients received one of the NOACs for 48 h-1 week. Patients who failed to transmit an ECG for three consecutive days or more than 7 days total were crossed over to continuous anticoagulation. Patients in the continuous group received one of the NOACs. Fifty-eight patients were randomized to either intermittent (n = 29) or continuous anticoagulation (n = 29). Over a median follow-up of 20 months, 20 patients in the intermittent group failed to submit a daily ECG at least once (median three failed submissions). Four patients (14 %) crossed over to continuous anticoagulation due to failure to submit an ECG for three consecutive days. One stroke (continuous group) occurred during the study. Major bleeding occurred in two patients in the continuous and one patient in the intermittent group, after crossing over to continuous anticoagulation. In a prespecified per-protocol analysis, gastrointestinal bleeding was more frequent in the continuous group (16 vs. 0 %; p = 0.047). Intermittent anticoagulation based on daily rhythm monitoring is feasible and may decrease bleeding in low-risk patients with paroxysmal AF. A larger trial, adequately powered to detect clinical outcomes, is warranted.

    Bleeding is a significant complication of anticoagulant therapy. With the emergence of new oral anticoagulants (NOACs; ie, direct factor IIa or Xa inhibitors), this risk is further compounded by the lack of validated reversal strategies for these agents. Emerging postmarketing evidence suggests that

    Warfarin oral anticoagulant therapy (OAT) requires regular and frequent drug adjustment monitored by INR. Interindividual variability, drug and diet interferences, and genetics (VKORC1 and CYP2C9) make the maintenance/reaching of stable INR a not so easy task. HPLC assessment of warfarin/enantiomers was suggested as a valid monitoring-tool along with INR, but definite results are still lacking. We evaluated possible correlations between INR, warfarin/3'-hydroxywarfarin, and drug weekly dosage aimed at searching novel alternatives to OAT monitoring. VKORC1/CYP2C9 pharmacogenetics investigation was performed to account for the known influence on warfarin homeostasis. 133 OAT patients were recruited and assessed for warfarin/3'-hydroxywarfarin serum levels (HPLC), INR, and VKORC1 and CYP2C9 genotypes. A subgroup of 52 patients were monitored in detail (5 consecutive controls; c0-c4) till the target INR was reached. Correlation analyses were performed in both groups. In the whole OAT group both warfarin and 3'-hydroxywarfarin correlate with INR at comparable degree (r2 = 0.0388 and 0.0362 respectively). Conversely, warfarin weekly dosage better correlates with warfarin than with 3'-hydroxywarfarin (r2 = 0.0975 and r2 = 0.0381 respectively), but considering together warfarin plus 3'-hydroxywarfarin the correlation strongly increased (r2 = 0.1114; ppharmacogenetics studies confirmed that patients carrying the VKORC1 variant-allele required lower warfarin maintenance dosage and that the combination of VKORC1 and CYP2C9 yielded a warfarin responsive index (WRI) inversely related to the number variant alleles. Our results overall suggest that 3'-hydroxywarfarin monitoring could be of great advantage in INR monitoring respect to classical warfarin assessment showing significant contribution also in multivariate analysis. Therefore, additional active metabolites should be recognized and investigated as novel useful indicators.

    Gastrointestinal bleeding (GIB) is a major problem in patients on oral anticoagulation therapy. This issue has become even more pressing since the introduction of direct oral anticoagulants (DOACs) in 2009. Areas covered: Here we review current evidence related to GIB associated with oral anticoagulants, focusing on randomized controlled trials, meta-analyses, and post-marketing observational studies. Dabigatran 150 mg twice daily and rivaroxaban 20 mg once daily increase the risk of GIB compared to warfarin. The risk increase with edoxaban is dose-dependent, while apixaban shows apparently, no increased risk. We summarize what is known about GIB risk factors for individual anticoagulants, the location of GIB in patients taking these compounds, and prevention strategies that lower the risk of GIB. Expert opinion: Recently there has been an important shift in the clinical presentation of GIB. Specifically, upper GIB has decreased with the decreased incidence of peptic ulcers due to the broad use of proton pump inhibitors and the decreased prevalence of H. pylori infections. In contrast, the incidence of lower GIB has increased, due in part to colonic diverticular bleeding and angiodysplasia in the elderly. In this population, the addition of oral anticoagulation therapy, especially DOACs, seems to increase the risk of lower GIB.

    Full Text Available Abstract Over the past 20 years, several proton beam treatment programs have been implemented throughout the United States. Increasingly, the number of new programs under development is growing. Proton beam therapy has the potential for improving tumor control and survival through dose escalation. It also has potential for reducing harm to normal organs through dose reduction. However, proton beam therapy is more costly than conventional x-ray therapy. This increased cost may be offset by improved function, improved quality of life, and reduced costs related to treating the late effects of therapy. Clinical research opportunities are abundant to determine which patients will gain the most benefit from proton beam therapy. We review the clinical case for proton beam therapy. Summary sentence Proton beam therapy is a technically advanced and promising form of radiation therapy.

    Full Text Available Abstract Background and objectives International Normalized Ratio (INR is a world-wide routinely used factor in the monitoring of oral anticoagulation treatment (OAT. However, it was reported that other factors, e. g. factor II, may even better reflect therapeutic efficacy of OAT and, therefore, may be potentialy useful for OAT monitoring. The primary purpose of this study was to characterize the associations of INR with other vitamin K-dependent plasma proteins in a heterogenous group of individuals, including healthy donors, patients on OAT and patients not receiving OAT. The study aimed also at establishing the influence of co-morbid conditions (incl. accompanying diseases and co-medications (incl. different intensity of OAT on INR. Design and Methods Two hundred and three subjects were involved in the study. Of these, 35 were normal healthy donors (group I, 73 were patients on medication different than OAT (group II and 95 were patients on stable oral anticoagulant (acenocoumarol therapy lasting for at least half a year prior to the study. The values of INR and activated partial thromboplastin time (APTT ratio, as well as activities of FII, FVII, FX, protein C, and concentration of prothrombin F1+2 fragments and fibrinogen were obtained for all subjects. In statistical evaluation, the uni- and multivariate analyses were employed and the regression equations describing the obtained associations were estimated. Results Of the studied parameters, three (factors II, VII and X appeared as very strong modulators of INR, protein C and prothrombin fragments F1+2 had moderate influence, whereas both APTT ratio and fibrinogen had no significant impact on INR variability. Due to collinearity and low tolerance of independent variables included in the multiple regression models, we routinely employed a ridge multiple regression model which compromises the minimal number of independent variables with the maximal overall determination coefficient.

    Patients receiving warfarin who experience minor head injury are at risk of intracranial hemorrhage, and optimal management after a single head computed tomography (CT) scan is unclear. We evaluate a protocol of 24-hour observation followed by a second head CT scan. In this prospective case series, we enrolled consecutive patients receiving warfarin and showing no intracranial lesions on a first CT scan after minor head injury treated at a Level II trauma center. We implemented a structured clinical pathway, including 24-hour observation and a CT scan performed before discharge. We then evaluated the frequency of death, admission, neurosurgery, and delayed intracranial hemorrhage. We enrolled and observed 97 consecutive patients. Ten refused the second CT scan and were well during 30-day follow-up. Repeated CT scanning in the remaining 87 patients revealed a new hemorrhage lesion in 5 (6%), with 3 subsequently hospitalized and 1 receiving craniotomy. Two patients discharged after completing the study protocol with 2 negative CT scan results were admitted 2 and 8 days later with symptomatic subdural hematomas; neither received surgery. Two of the 5 patients with delayed bleeding at 24 hours had an initial international normalized ratio greater than 3.0, as did both patients with delayed bleeding beyond 24 hours. The relative risk of delayed hemorrhage with an initial international normalized ratio greater than 3.0 was 14 (95% confidence interval 4 to 49). For patients receiving warfarin who experience minor head injury and have a negative initial head CT scan result, a protocol of 24-hour observation followed by a second CT scan will identify most occurrences of delayed bleeding. An initial international normalized ratio greater than 3 suggests higher risk. Copyright © 2011 American College of Emergency Physicians. Published by Mosby, Inc. All rights reserved.

    An adult, intact female Australian shepherd presented for frank vaginal bleeding of unknown duration. The only coagulation profile abnormality upon presentation was mild prolongation of the partial thromboplastin time (PTT). The uterus was removed at surgery and contained a large amount of coagulated blood. Clotting profiles were markedly abnormal48 hours postoperatively. Serum analysis was positive for brodifacoum, an anticoagulant rodenticide. Preoperative coagulation was most likely normalized by vitamin K-1 therapy administered prior to presentation. The only manifestation of anticoagulant rodenticide was hematometra. Rodenticide intoxication should be considered in the differential diagnosis list of hematometra or metrorrhagia

    Atrial fibrillation (AF) is the most commonly diagnosed arrhythmia in clinical practice, and is associated with a significant medical and economic burden. Anticoagulants reduce the risk of stroke and systemic embolism by approximately two-thirds compared with no therapy. Knowledge regarding anticoagulant therapy can influence treatment outcomes in patients with AF. To measure the level of anticoagulation knowledge in patients with AF taking oral anticoagulants (OACs), investigate the association between patient-related factors and anticoagulation knowledge, and compare these results in patients taking warfarin and direct-acting oral anticoagulant (DOACs). Participants were recruited for an online survey via Facebook. Survey components included the Anticoagulation Knowledge Tool, the Perception of Anticoagulant Treatment Questionnaires (assessing treatment expectations, convenience and satisfaction), a modified Cancer Information Overload scale and the Morisky Medication Adherence Scale. Treatment groups were compared and predictors of OAC knowledge were identified. Participants taking warfarin had a higher knowledge score compared with those taking DOACs (n = 386, 73% ± 13% vs 66% ± 14%, Pcounselling sessions to help identify and resolve knowledge deficits. © 2018 John Wiley & Sons Ltd.

    Oral anticoagulation (OAC) is the recommended therapy for patients with atrial fibrillation (AF) because it reduces the risk of stroke and other thromboembolic events. Dual antiplatelet therapy (DAPT) is required after percutaneous coronary intervention and stenting (PCI-S). In patients with AF requiring PCI-S, the association of DAPT and OAC carries an increased risk of bleeding, whereas OAC therapy or DAPT alone may not protect against the risk of developing new ischemic or thromboembolic events. The MUSICA-2 study will test the hypothesis that DAPT compared with triple therapy (TT) in patients with nonvalvular AF at low-to-moderate risk of stroke (CHADS2 score ≤2) after PCI-S reduces the risk of bleeding and is not inferior to TT for preventing thromboembolic complications. The MUSICA-2 is a multicenter, open-label randomized trial that will compare TT with DAPT in patients with AF and CHADS2 score ≤2 undergoing PCI-S. The primary end point is the incidence of stroke or any systemic embolism or major adverse cardiac events: death, myocardial infarction, stent thrombosis, or target vessel revascularization at 1 year of PCI-S. The secondary end point is the combination of any cardiovascular event with major or minor bleeding at 1 year of PCI-S. The calculated sample size is 304 patients. The MUSICA-2 will attempt to determine the most effective and safe treatment in patients with nonvalvular AF and CHADS2 score ≤2 after PCI-S. Restricting TT for AF patients at high risk for stroke may reduce the incidence of bleeding without increasing the risk of thromboembolic complications. © 2013.

    Atrial fibrillation is the most common significant cardiac arrhythmia and is associated with a five-fold increased risk of stroke from thromboembolism. Over 94% of these emboli arise from the left atrial appendage. Systemic embolic phenomena are rare, accounting for less than 1 out of 10 of all embolic events, but have a similar prevention strategy. Anticoagulation significantly reduces the risk of these events, and thus forms the cornerstone of therapy for most patients with atrial fibrillation. Left atrial appendage occlusion with the Watchman device is a recently approved alternative for stroke prevention in selected patients. We present a case of an active duty U.S. Navy sailor at low risk for thromboembolism who nonetheless suffered recurrent thromboembolic events despite appropriate anticoagulation, and thus underwent Watchman implantation. The therapy in this case will ideally provide a lifetime of protection from recurrent systemic embolization while allowing the patient to continue his active duty military career without restriction due to oral anticoagulation.

    Non-bacterial thrombotic endocarditis (NBTE) is characterized by presence of sterile vegetations that develop from fibrin and platelets on heart valves. The main conditions predisposing to NBTE are malignancy, autoimmune diseases and other hypercoagulable states. The authors describe a case of a 25-year-old male, in whom NBTE was diagnosed on the bicuspid aortic valve. The presence of significant aortic regurgitation and dental caries were initially suggestive of infective endocarditis; although, serial blood culture were negative and procalcytonin concentration was within normal ranges. Empiric antibiotic therapy did not result in diminishing of vegetations, similarly to the anticoagulation treatment initiated when strongly positive lupus anticoagulant was detected in laboratory findings. Aortic valve replacement was necessary. Bacteriologic examination of the excised valve was negative. Widespread fibrin masses at different stages of organization on the leaflets confirmed NBTE in histopathologic assessment. Lupus anticoagulant was probably secondary to thyroid autoimmune disease. © 2016 MEDPRESS.

    Anticoagulation treatment was recently improved by the introduction of novel oral anticoagulants (NOACs). Using a combination of qualitative and quantitative methods, this study explores the effects of the introduction of NOACs on anticoagulation care in Slovenia. Face-to-face interviews with key stakeholders revealed evolvement and challenges of anticoagulation care from different perspectives. Obtained information was further explored through the analysis of nationwide data of drug prescriptions and realization of health care services. Simplified management of anticoagulation treatment with NOACs and their high penetration expanded the capacity of anticoagulation clinics, and consequentially the treated population increased by more than 50 % in the last 5 years. The main challenge concerned the expenditures for medicines, which increased approximately 10 times in just a few years. At the same time, the anticoagulation clinics and their core organisation were not affected, which is not expected to change, since they are vital in delivering high-quality care.

    Pheochromocytoma is a rare catecholamine-producing tumor, discovered incidentally in 50% of cases. We present the case of a 44-year-old male with a history of paroxysmal palpitations. Baseline ECG, transthoracic echocardiogram and ECG stress test showed no relevant alterations. Paroxysmal atrial fibrillation was detected on 24-hour Holter ECG. After antiarrhythmic therapy, the patient remained symptomatic, and was accordingly referred for electrophysiological study and atrial fibrillation ablation. Anticoagulation was initiated before the procedure. After ablation and still anticoagulated, he complained of hematospermia. The abdominal and pelvic imaging study showed a 10-cm left adrenal mass, predominantly cystic, compatible with pheochromocytoma, which was confirmed after biochemical tests (increased urine metanephrines and plasma catecholamines). Metaiodobenzylguanidine scintigraphy scanning confirmed localized disease in the adrenal gland, excluding other uptake foci. Following appropriate preoperative management, surgical resection of the giant mass was performed successfully and without complications. Copyright © 2013 Sociedade Portuguesa de Cardiologia.

    Direct oral anticoagulants (DAOC) are indicated for the treatment of venous thromboembolism and the prevention of stroke or systemic embolism in patients with non-valvular atrial fibrillation. Given their advantages and friendly use for patient, the prescription of long term DOAC therapy has rapidly increased both as first line treatment while initiating anticoagulation and as a substitute to vitamins K antagonist (VKA) in poorly controlled patients. However, DOAC therapy can also be associated with significant bleeding complications, and in the absence of specific antidote at disposal, treatment of serious hemorrhagic complications under DOAC remains complex. We report and discuss herein five cases of major hemorrhagic complications under DOAC, which were reported to the pharmacological surveillance department over one year at Saint-Louis University Hospital (Paris, France). We further discuss the need for careful assessment of the risk/benefit ratio at time of starting DOAC therapy in daily clinical practice. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

    Full Text Available Thyroid storm is a life-threatening condition that occurs secondary to an uncontrolled hyperthyroid state. Atrial fibrillation is a cardiovascular complication occurring in up to 15% of patients experiencing thyroid storm, and if left untreated this condition could have up to a 25% mortality rate. Thyroid storm with stroke is a rare presentation. This case report details a left middle cerebral artery (MCA stroke with global aphasia and thyroid storm in a 53-year-old Hispanic male patient. Although uncommon, this combination has been reported in multiple case series. Although it is well documented that dysfunctional thyroid levels promote a hypercoagulable state, available guidelines from multiple entities are unclear on whether anticoagulation therapy is appropriate in this situation.

    Full Text Available Venous thrombosis and pulmonary embolism in healthy military are rare. Fighting surgical trauma is the trigger of a cascade of defense reactions of the body and the blood coagulation system, leading to stop bleeding. Hemostatic disorders, shifting the equilibrium toward hypercoagulable state, the emergence of the risk factors associated with the injury, lead to uncontrolled thrombosis with subsequent development of venous thromboembolic complications. We present the case of the left pulmonary artery thromboembolism in 41 year old wounded with a gunshot fracture of the right femur, obtained by blowing an unknown explosive device. Medical assistance was provided in three stages of evacuation. In order to stabilize a femur fracture the external fixation device was used. According coagulogram thrombinemia persisted for more than 30 days. Prevention of thrombosis carried LMWH (Clexane, with 9 days after injury. 31 day angiography was performed computer, identified thrombus by 70% ceiling clearance left pulmonary artery; by ultrasound scanning of the veins of the lower limbs was diagnosed asymptomatic thrombosis of the right iliofemoral. Against the background of complex treatment for 67 hours after the injury occurred recanalization. This case shows that the injured limb wound clinical symptoms of the disease symptoms negate venous thrombosis, which becomes the only manifestation of pulmonary embolism. Prevention of venous thromboembolic events, as well as monitoring of its effectiveness, should be carried out at all stages of the evacuation of the wounded and for the entire period of the presence of risk factors for their development.

    Intra and perioperative anticoagulation in patients with heparin induced thrombocytopenia (HIT), candidates for peripheral vascular surgery remains a challenge, as the best alternative to heparin has not yet been established. We evaluated the off-label use of fondaparinux in four patients with HIT, undergoing peripheral vascular surgery procedures. Four patients of whom 3 men of a mean age of 66 years, with proven heparin induced thrombocytopenia (HIT) underwent two axillo-femoral bypasses, one femoro-popliteal bypass and one resection of a splenic artery aneurysm under fondaparinux. No intra or perioperative bleeding or thrombosis of new onset was observed. In the absence of a valid alternative to heparin for intra and perioperative anticoagulation in HIT, several other anticoagulants can be used in an off-label setting. However, no general consensus exist on which should be the one of choice. In this small series fondaparinux appeared to be both safe and effective. These preliminary results seem to justify the off-label use of fondaparinux for intra and perioperative anticoagulation in patients with HIT, candidates for peripheral vascular surgery interventions.

    Full Text Available Simon J McRae, Jeffrey S GinsbergDepartment of Medicine, McMaster University, Hamilton, ON, CanadaAbstract: Anticoagulant therapy is effective at preventing the development of venous thromboembolism in high-risk patients, and reduces morbidity and mortality in individuals with established thromboembolic disease. Vitamin K antagonists and heparins are currently the most commonly used anticoagulant drugs, but they have practical limitations. Therefore, new antithrombotic agents with predictable dose-responses (thereby decreasing the need for monitoring without compromising efficacy or safety, ideally available in an oral formulation and with a rapidly reversible anticoagulant effect, are needed. New drugs fulfilling some of the above criteria have been developed and have proven to be effective agents for the treatment and prevention of venous thromboembolism.Keywords: venous thromboembolism, anticoagulants, antithrombotic

  1. Fall risk and anticoagulation for atrial fibrillation in the elderly: A delicate balance.

    Guidelines for managing atrial fibrillation recommend systemic anticoagulation for almost all patients age 65 and older, but in practice up to 50% of older patients do not receive maintenance anticoagulation therapy. The most common reason physicians cite for withholding anticoagulation in older patients with atrial fibrillation is a perception of a high risk of falling and associated bleeding, especially intracranial hemorrhage.

    Femoral neuropathy occurs when occult retroperitoneal bleeding impinges on the appropriate nerve roots. The syndrome involves the acute onset of groin and thigh pain with characteristic flexion and external rotation of the hip. It may mimic other conditions such as acute arterial occlusion. Thorough knowledge of the anatomy of the femoral nerve explains the clinical features and leads the clinician to suspect the occurrence of this syndrome. Three cases have been reviewed that exhibited this condition as a result of retroperitoneal bleeding, a complication of systemic heparin therapy. The hemophilia that afflicted Alexis, the Crown Prince of Russia and son of Tsar Nicholas and Tsarina Alexandra, resulted in this clinical syndrome. The consequences enabled the sinister starets, Gregory Rasputin, to become intimately involved with the royal family, influencing the response of the Tsar to the political events in Russia, thereby playing an important role in setting the stage for the 1917 Russian communist revolution.

    Vitamin K antagonists were the only choice for chronic oral anticoagulation for more than half a century. Over the past few years, direct oral anticoagulants have emerged, including one direct thrombin inhibitor (dabigatran etexilate) and three factor Xa inhibitors (apixaban, edoxaban and rivaroxaban). In randomised controlled trials comparing direct oral anticoagulants with traditional vitamin K antagonists, the direct oral anticoagulants all showed a favourable benefit-risk balance in their safety and efficacy profile, in prevention of thromboembolic events in patients with atrial fibrillation and in the prevention and treatment of venous thromboembolism and acute coronary syndrome. In 2008, dabigatran was the first direct oral anticoagulant approved by the European Medicine Agency. Subsequently, rivaroxaban, apixaban and edoxaban were also authorised. This article reviews the evidence related to the use of these drugs. Copyright © 2017 Elsevier España, S.L.U. All rights reserved.

    To evaluate Korean physiatrists' practice of performing intramuscular botulinum toxin injection in anticoagulated patients and to assess their preference in controlling the bleeding risk before injection. As part of an international collaboration survey study, a questionnaire survey was administered to 100 Korean physiatrists. Physiatrists were asked about their level of experience with botulinum toxin injection, the safe international normalized ratio range in anticoagulated patients undergoing injection, their tendency for injecting into deep muscles, and their experience of bleeding complications. International normalized ratio injection by 41% of the respondents. Thirty-six respondents replied that the international normalized ratio should be lowered to sub-therapeutic levels before injection, and 18% of the respondents reported that anticoagulants should be intentionally withheld and discontinued prior to injection. In addition, 20%-30% of the respondents answered that they were uncertain whether they should perform the injection regardless of the international normalized ratio values. About 69% of the respondents replied that they did have any standardized protocols for performing botulinum toxin injection in patients using anticoagulants. Only 1 physiatrist replied that he had encountered a case of compartment syndrome. In accordance with the lack of consensus in performing intramuscular botulinum toxin injection in anticoagulated patients, our survey shows a wide range of practices among many Korean physiatrists; they tend to avoid botulinum toxin injection in anticoagulated patients and are uncertain about how to approach these patients. The results of this study emphasize the need for formulating a proper international consensus on botulinum toxin injection management in anticoagulated patients.

Specific antidotes to NOACs are under development. Idarucizumab (aDabi-Fab, BI 655075 is a novel humanized mouse monoclonal antibody that binds dabigatran and reverses its anticoagulant effect. In a recent Phase III study (Reversal Effects of Idarucizumab on Active Dabigatran, a 5 g intravenous infusion of idarucizumab resulted in the normalization of dilute thrombin time in 98% and 93% of the two groups studied, with normalization of ecarin-clotting time in 89% and 88% patients. Two other antidotes, andexanet alfa (PRT064445 and ciraparantag (PER977 are also under development for reversal of NOACs. In this review, we discuss commonly encountered management issues with NOACs such as periprocedural management, laboratory monitoring of anticoagulation, and management of bleeding.

    Abnormal uterine bleeding (AUB) is a common complication of anticoagulant therapy in premenopausal women affected with acute venous thromboembolism. AUB impacts quality of life, and can lead to premature cessation of anticoagulation. There is increasing data to suggest that the direct oral anticoagulants when used for the treatment of venous thromboembolism differ in their menstrual bleeding profile. This article aims to review the existing literature regarding the association between AUB and the direct oral anticoagulants and make practical recommendations. Copyright © 2017 Elsevier Inc.

A new oral anticoagulation treatment, dabigatran etexilate, is already on the market in Europe. The main interest probably will be to improve the prescription and the adherence to an effective thromboprophylaxis in medical conditions such as atrial fibrillation without bleeding side effects, without the need for monitoring coagulation, and without drug and food interactions such as vitamin K anticoagulant (VKA treatment. Dabigatran is particularly interesting for extended thromboprophylaxis after major orthopedic surgery in order to avoid daily injection for a month. However, oral long-term treatments such as VKA are not systematically associated with a higher compliance level than injected treatments such as low-molecular-weight heparins. Indeed, adherence to an oral treatment, instead of the usual daily injection in major orthopedic surgery, is complex, and based not only on the frequency of dosing but also on patient motivation, understanding, and socio-economic status. New oral anticoagulants may be useful in this way but education and detection of risk factors of nonadherence to treatment are still essential.Keywords: oral anticoagulant, adherence, compliance, education, dabigatran

    The initiation of oral anticoagulation therapy after valve replacement surgery requires strict monitoring because these patients are at high risk for the development of thrombotic complications and present an increased risk of bleeding. The aim of this study was to examine the total healthcare costs of oral anticoagulant treatment with vitamin K antagonists in patients with metallic prosthetic valves in the mitral position. Data from clinical records were used in the study including international normalized ratio results, number of medical visits, type of anticoagulant, use of rescue medication and hospital admissions from related complications. The drug cost was calculated based on the official Spanish Ministry of Health price list. Monitoring expenses were included in the cost of the medical supplies used in the procedures. Hospitalization costs were calculated using the diagnosis-related group price for each case. We collected data from 151 patients receiving oral anticoagulation therapy with vitamin K antagonist who were diagnosed with mitral prosthesis (n = 90), mitro-aortic prosthesis (n = 57), and mitral and tricuspid prosthesis (n = 4). The total direct healthcare cost was €15302.59, with a mean total cost per patient per year of €1558.15 (±2774.58) consisting of 44.38 (±42.30) for drug cost, €71.41 (±21.43) for international normalized ratio monitoring, €429.52 (±126.87) for medical visits, €26.31 (±28.38) for rescue medication and €986.53 (±2735.68) for related complications. Most direct healthcare costs associated with the sampled patients arose from the specialist-care monitoring required for treatment. Good monitoring is inversely related to direct healthcare costs.

    For years, the pharmaceutical industry has been trying to find a safe and effective drug to replace warfarin. Although warfarin is an effective anticoagulant, its pharmacology, adverse effects, and risk profiles dictate that patients taking this medication must be monitored judiciously. The US Food and Drug Administration has approved two drugs for commercial use, dabigatran and rivaroxaban, that will compete directly with warfarin for use in specific indications. Because of direct marketing to patients, physicians are being asked to comment on these new medications. This brief review illustrates the data available for the two new drugs when compared to warfarin for the specified indications. For some patients, these drugs may be highly beneficial and offer an excellent alternative to warfarin. For others, warfarin may still be the preferred drug.

However, recent literature and epidemiologic data suggest that for certain patient populations the frequency is higher (1 in 3,000. Due to safety concerns of bleeding risk, guidelines and recommendations have been designed to reduce patient morbidity/mortality during regional anesthesia. Data from evidence-based reviews, clinical series and case reports, collaborative experience of experts, and pharmacology used in developing consensus statements are unable to address all patient comorbidities and are not able to guarantee specific outcomes. No laboratory model identifies patients at risk, and rarity of neuraxial hematoma defies prospective randomized study so “patient-specific” factors and “surgery-related” issues should be considered to improve patient-oriented outcomes. Details of advanced age, older females, trauma patients, spinal cord and vertebral column abnormalities, organ function compromise, presence of underlying coagulopathy, traumatic or difficult needle placement, as well as indwelling catheter(s during anticoagulation pose risks for significant bleeding. Therefore, balancing between thromboembolism, bleeding risk, and introduction of more potent antithrombotic medications in combination with regional anesthesia has resulted in a need for more than “consensus statements” to safely manage regional interventions during anticoagulant/thromboprophylactic therapy.

    2015-09-01

    Full Text Available Electric external cardioversion (EEC for permanent atrial fibrillation (AF carries a risk of thromboembolic events (TE. The use of transesophageal echocardiography (TEE to guide the management of atrial fibrillation may be considered a clinically effective alternative strategy to conventional therapy for patients in whom elective cardioversion is planned. Therapeutic anticoagulation with novel oral anticoagulants (NOAC is recommended for 3 to 4 weeks before and an anticoagulation life-long therapy is recommended after EEC to reduce TE, in patients with high CHA2DS2-VASc score; however, only few data are currently available about safety of shortterm anticoagulation with NOAC in the setting of EEC. Patients with increased risk of thromboembolism have not been adequately studied and the monitoring of anticoagulant effects can also have important benefits in case of drug interactions. We report a case of a 68-year old man with AF from September 2014. Moderate depression of global left ventricular systolic function was detected by echocardiographic exam. On the basis of a high thromboembolic risk, an anticoagulant therapy with rivaroxaban, at the dose of 20 mg/day, was started. TEE showed a thrombus in the left atrial appendage. This case demonstrates the utility of performing TEE prior than EEC in patients with hypokinetic cardiomyopathy other than AF in therapy with NOAC. We underline the presence of significant pharmacodynamic interference of rivaroxaban with other drugs such as oxcarbazepine.

    Clinical outcomes and the effects of oral anticoagulants among patients with acute coronary syndrome (ACS) and either a history of or acute heart failure (HF) are largely unknown. We aimed to assess the relationship between prior HF or acute HF complicating an index ACS event and subsequent clinical outcomes and the efficacy and safety of apixaban compared with placebo in these populations. High-risk patients were randomly assigned post-ACS to apixaban 5.0 mg or placebo twice daily. Median follow-up was 8 (4-12) months. The primary outcome was cardiovascular death, myocardial infarction, or stroke. The main safety outcome was thrombolysis in myocardial infarction major bleeding. Heart failure was reported in 2,995 patients (41%), either as prior HF (2,076 [28%]) or acute HF (2,028 [27%]). Patients with HF had a very high baseline risk and were more often managed medically. Heart failure was associated with a higher rate of the primary outcome (prior HF: adjusted hazard ratio [HR] 1.73, 95% CI 1.42-2.10, P acute HF: adjusted HR 1.65, 95% CI 1.35-2.01, P acute HF: adjusted HR 2.52, 95% CI 1.82-3.50). Patients with acute HF also had significantly higher rates of thrombolysis in myocardial infarction major bleeding (prior HF: adjusted HR 1.22, 95% CI 0.65-2.27, P = .54, acute HF: adjusted HR 1.78, 95% CI 1.03-3.08, P = .04). There was no statistical evidence of a differential effect of apixaban on clinical events or bleeding in patients with or without prior HF; however, among patients with acute HF, there were numerically fewer events with apixaban than placebo (14.8 vs 19.3, HR 0.76, 95% CI 0.57-1.01, interaction P = .13), a trend that was not seen in patients with prior HF or no HF. In high-risk patients post-ACS, both prior and acute HFs are associated with an increased risk of subsequent clinical events. Apixaban did not significantly reduce clinical events and increased bleeding in patients with and without HF; however, there was a tendency toward fewer clinical

    The general function of anticoagulants is to prevent blood clotting and growing of the existing clots in blood vessels. In recent years, there has been a significant improvement in developing methods of prevention as well as pharmacologic and surgical treatment of thrombosis. For over the last two decades, low molecular weight heparins (LMWHs) have found their application in the antithrombotic diseases treatment. These types of drugs are widely used in clinical therapy. Despite the biological and medical importance of LMWHs, they have not been completely characterized in terms of their chemical structure. Due to both, the structural complexity of these anticoagulants and the presence of impurities, their structural characterization requires the employment of advanced analytical techniques. Since separation techniques play the key role in these endeavors, this review will focus on the presentation of recent developments in the separation of LMWH anticoagulants.

    Full Text Available Background: This study examined the annual prevalence of atrial fibrillation (AF and its associated comorbidities, as well as the prevalence of warfarin therapy in South Korean patients with AF. Methods: The National Health Insurance Service-National Sample Cohort database was searched for subjects aged ≥30 years diagnosed with AF from 2002–2013. The prevalence of AF was analyzed by sex and age, as was the current status of warfarin therapy in AF patients according to CHA2DS2-VASc score and comorbidities. Results: The age-standardized prevalence of AF in men and women was 0.15% and 0.14%, respectively, in 2002, increasing to 0.54% and 0.39%, respectively, in 2013. In 2013, the prevalence of AF in men and women aged 30–39 years was 0.08% and 0.03%, respectively, increasing to 2.35% and 1.71%, respectively, in those in aged ≥60 years. During 2002–2013, the prevalence of AF in men significantly increased among subjects aged ≥30 years and increased in women aged ≥60 years. The age-standardized prevalence of hypertension and diabetes mellitus among AF patients were markedly increased during 2002–2013. Of these AF patients, 86.1% had a CHA2DS2-VASc score of ≥2; however, only 39.1% of these were receiving warfarin. Conclusions: The age-standardized prevalence of AF increased 2.89-fold over the 12-year study period. The total number of patients with AF in South Korea has been drastically increasing, due to not only aging society but also increasing age-specific prevalence of AF, especially in middle-aged and elderly individuals. The rate of warfarin therapy increased slightly over the study period but remains low.

    To describe the population admitted in an emergency department of a teaching hospital for severe bleeding associated with direct oral anticoagulants (DOAC). During a three-year period (2012-2014) patients older than 16 years were prospectively identified by haemorrhagic symptoms from computerised requests. At least one of the following criteria defined major haemorrhage: haemorrhagic shock, unstable haemodynamic, need for transfusion or haemostatic procedure, or a life threatening location. Fifty four patients, 23 receiving dabigatran, 30 rivaroxaban and one apixaban were included, 2 in 2012, 35 in 2013 and 17 in 2014. Median age was 84 years (range 63-99) with a sex ratio of 1.16. Haemorrhagic complications were gastrointestinal (n=27), intracranial (n=12) or miscellaneous (n=15). Indication of DOAC was stroke prevention in atrial fibrillation in 49 cases and deep vein thrombosis in 5 cases. Hospitalization was required for 45 patients (83%) with a mean length of stay of 8.5 days. Sixteen patients needed intensive care. Reversal therapy was prescribed in 11 patients. At 1 month, overall mortality was 24%, reaching 41.7% for intracranial haemorrhage. Among surviving patients, DOAC was stopped in 10 cases, continued in 17 patients and switched for other antithrombotic in 17 patients. Our study contributes to the post marketing surveillance of major haemorrhagic complications associated with DOAC. It takes part to the knowledge about the course of this severe event in emergencies. Careful awareness in risk benefit assessment, especially in elderly, is needed. Copyright © 2015 Elsevier Ltd. All rights reserved.

The following data was collected from patients presenting AF: medical history including treatment and comorbidities, CHADS2 score, ISAR scale (frailty, Lawton’s scale (ADL, GDS scale (mood status, MUST (nutrition, and blood analysis (INR, kidney function, and albumin. Among those patients for who anticoagulation treatment was recommended (73%, only 61% were treated with it. In the group with anticoagulation therapy, the following characteristics were observed more often than in the group without such therapy: a recent (≤6 months hospitalization and medical treatment including digoxin or based on >3 different drugs. Neither the value of the CHADS2 score, nor the geriatric characteristics could be correlated with the presence or the absence of an anticoagulation therapy. More research is thus required to identify and clarify the relative importance of patient-, physician-, and health care system-related hurdles for the prescription of oral anticoagulation therapy in older patients with AF.

    Full Text Available The objective of the present study is to further elucitate the specifics cognitive behavioural therapy (CBT based on the treatment of 2 patients. The theoretical background of the therapy is based on the idea that the learning processes determine behaviour (behavioural therapy, acquisition and consolidation of beliefs and view of the world (cognitive therapy. The CBT is short-term (usually 12–20 weekly sessions. It assumes close links between the patient’s thoughts (about self, the world and the future and his/her emotions, behaviour and physiology. The patient’s work in between sessions consists in observation of their own thoughts, behaviours, and emotions, and introduction of changes within the scope of their thoughts and behaviours. The goal of cognitive behavioural therapy is autonomy and independence of a patient, attainment of the patient’s objectives, and remedying the most important problems of the patient. The therapist should be active, warm and empathic. Cognitive behavioural therapy is structured and active. Between sessions, the patient receives homework assignments to complete. During therapy, information is collected by experiments and verification of hypotheses. It should be emphasized that for changes to occur in the process of psychotherapy it is necessary to establish a strong therapeutic alliance.

  6. Anticoagulants Influence the Performance of In Vitro Assays Intended for Characterization of Nanotechnology-Based Formulations

    Full Text Available The preclinical safety assessment of novel nanotechnology-based drug products frequently relies on in vitro assays, especially during the early stages of product development, due to the limited quantities of nanomaterials available for such studies. The majority of immunological tests require donor blood. To enable such tests one has to prevent the blood from coagulating, which is usually achieved by the addition of an anticoagulant into blood collection tubes. Heparin, ethylene diamine tetraacetic acid (EDTA, and citrate are the most commonly used anticoagulants. Novel anticoagulants such as hirudin are also available but are not broadly used. Despite the notion that certain anticoagulants may influence assay performance, a systematic comparison between traditional and novel anticoagulants in the in vitro assays intended for immunological characterization of nanotechnology-based formulations is currently not available. We compared hirudin-anticoagulated blood with its traditional counterparts in the standardized immunological assay cascade, and found that the type of anticoagulant did not influence the performance of the hemolysis assay. However, hirudin was more optimal for the complement activation and leukocyte proliferation assays, while traditional anticoagulants citrate and heparin were more appropriate for the coagulation and cytokine secretion assays. The results also suggest that traditional immunological controls such as lipopolysaccharide (LPS are not reliable for understanding the role of anticoagulant in the assay performance. We observed differences in the test results between hirudin and traditional anticoagulant-prepared blood for nanomaterials at the time when no such effects were seen with traditional controls. It is, therefore, important to recognize the advantages and limitations of each anticoagulant and consider individual nanoparticles on a case-by-case basis.

    Full Text Available Background: Over the last years, the use of oral anticoagulant treatment has increased dramatically, principally for the prevention of venous thrombosis and thrombembolic events. This treatment is demanding, especially among the elderly with concommitant diseases and different medication. Aim of the study to evaluate the rate of serious complications, clinically significant hemorrhage from upper gastointestinal tract in patients treated with oral antiocoagulants in a prospective cohort study.Patients and methods: Included were patients admitted to our institution between January 1, 1994 and December 31, 2003 due to gastrointestinal hemorrhage. Emergency endoscopy and laboratory testing was performed in all patients.Results: 6416 patients were investigated: 2452 women (38.2 % and 3964 men (61.8 %, mean age 59.1 years, SD 17.2. Among our patients, 55 % were aged over 60 years. In 86.4 % of patients the source of bleeding was confirmed in the upper gastrointestinal tract. In the last week prior to bleeding, 20.4 % (1309/6416 of all patients were regularly taking nonsteroidal anti-inflammatory drugs, anticoagulant therapy or antiplatelet agents in single daily doses at least. 6.3 % of patients (82/1309 with abundant hemorrhage from upper gastrointestinal tract were using oral anticoagulant therapy and had INR > 5 at admission, 25.6 % of them had INR > 10. The mortality of patients using oral anticoagulants and INR > 5 was 17.1 %.Conclusions: Upper gastrointestinal hemorrhage is a serious complication of different medications, particularly in elderly patients. Safe use of anticoagulant therapy is based on careful selection of patients and correct intake of the prescribed drugs.

  10. Standards of care issues with anticoagulation in real-world populations.

    Science.gov (United States)

    2015-01-01

    Current guidelines recommend anticoagulants for reducing the risk of stroke in appropriate patients with nonvalvular atrial fibrillation (NVAF) and for the acute treatment of venous thromboembolism (VTE) and the prevention of recurrent VTE. Warfarin is the standard of care for both NVAF and VTE, yet International Normalized Ratio (INR) control remains suboptimal, even in the clinical trial setting. Maintaining INR within the recommended therapeutic range is associated with better outcomes in these distinct populations. In VTE, high rates of recurrence have been reported during the first few weeks of treatment, emphasizing the importance of surveillance during this time and of early optimization of anticoagulation therapy. The NVAF population tends to have more comorbidities and requires longer-term therapy. It is important to keep in mind that real-world patient populations are more complex than those in controlled studies. Patients with multiple comorbidities are particularly challenging, and physicians may focus on clinically urgent issues rather than anticoagulation optimization. Despite the many complexities associated with the use of warfarin, it remains a mainstay of anticoagulation therapy. Aligning financial incentives and improving care coordination are important factors in moving toward better outcomes for patients who need anticoagulation therapy. The increased focus on value-based care and evolving approaches to patient treatment could lead more physicians and payers to consider alternatives to warfarin, including the use of novel oral anticoagulants.

    Full Text Available Spontaneous sublingual hematoma and intramural small bowel hematoma are rare and serious complications of anticoagulant therapy. Though previously reported individually, there has been no previous report of the same two complications occurring in a single patient. A 71-year-old Caucasian man, who was on warfarin for atrial fibrillation, presented with difficulty in swallowing due to a sublingual hematoma. He was observed in our intensive care unit, his warfarin was held and he recovered with conservative management. He represented two months later with a two day history of abdominal pain and distension. An abdominopelvic computed tomography (CT scan now showed small bowel obstruction due to intramural small bowel hematoma and haemorrhagic ascites. Again, this was treated expectantly with a good outcome. In conclusion, life threatening haemorrhagic complications of oral anticoagulant therapy can recur. Conservative treatment is successful in most cases, but an accurate diagnosis is mandatory to avoid unnecessary surgery. CT scan is the investigation of choice for the diagnosis of suspected haemorrhagic complications of over coagulation.

    We describe an unusual case of recurrent, refractory anterior epistaxis in an 86-year-old man with two mechanical heart valves who was on permanent warfarin therapy. His numerous episodes of epistaxis were incited by chronic nose-picking and strong nose-blowing, practices that he continued to engage in despite repeated medical advice to stop. Stopping his anticoagulation therapy was not considered as a management option because of an unacceptably high risk that this would lead to a thromboembolic event. Eventually, we temporarily sutured his nares closed, and his nosebleeds ceased. The suturing was performed in the ward with local anesthesia. This procedure was simple to perform,fairly well tolerated, easily reversible, and highly effective.

    Full Text Available Intramural hematoma is a clinical situation which is secondary to anticoagulant therapy. In this study, a chronic atrial fibrilation patient taking anticoagulant, had perforation at rectosigmoid region which was secondary to intramural hematoma, is presented. Our case was a eighty-three-year-old male presented with acute abdomen at emergency room. In computerized tomography, intraabdominal free air and hematoma at rectosigmoid region were seen. Due to these, the decision of immidiate exploration was made. This should be noted that intramural hematoma can emerge in patientd on anticoagulant theraphy without trauma. Additionally, it shold be considered that intramural hematoma can lead to lethal complication such as perforation.

    Abstract Currently, there are few guidelines for the use of vitamin K1 in the maintenance treatment of long-acting anticoagulant rodenticide (LAAR) poisonings. We explored factors in the treatment of LAAR poisoning during the maintenance period in order to suggest feasible treatment models. Data from 24 cases of anticoagulant rodenticide poisoning in our hospital were collected from January 2013 to May 2016. The patients’ sex, age, coagulation function, total time from poisoning to treatment with vitamin K1 (prehospital time), vitamin K1 sustained treatment time (VKSTT), anticoagulant rodenticide category, and specific poison dosage were collected. Multivariate analysis was used to evaluate the correlation between vitamin K1 dosage and other factors during the maintenance period. Only VKSTT (partial regression coefficient −1.133, 0.59, P = 0.035) had an obvious influence on the therapeutic dose of vitamin K1 required during the maintenance period. After an initial pulse therapy, the bleeding and coagulation functions were stabilized, and the patients were subsequently treated with vitamin K1 during the maintenance period. Over time, the maintenance dose of vitamin K1 (10–120 mg/d, intravenous drip) was gradually decreased and was not related to toxicant concentration. PMID:28002326

    Vitamin K antagonists, such as warfarin, are standard treatments for stroke prophylaxis in patients with atrial fibrillation. Patient outcomes depend on quality of warfarin management, which includes regular monitoring and dose adjustments. Recently, novel oral anticoagulants (NOACs) that do not require regular monitoring offer an alternative to warfarin. The aim of this study was to evaluate whether cost effectiveness of NOACs for stroke prevention in atrial fibrillation depends on the quality of warfarin control. We developed a Markov decision model to simulate warfarin treatment outcomes in relation to the quality of anticoagulation control, expressed as percentage of time in the therapeutic range (TTR). Standard treatment with adjusted-dose warfarin and improved anticoagulation control by genotype-guided dosing were compared with dabigatran, rivaroxaban, apixaban and edoxaban. The analysis was performed from the Slovenian healthcare payer perspective using 2014 costs. In the base case, the incremental cost-effectiveness ratio for apixaban, dabigatran and edoxaban was below the threshold of €25,000 per quality-adjusted life-years compared with adjusted-dose warfarin with a TTR of 60%. The probability that warfarin was a cost-effective option was around 1%. This percentage rises as the quality of anticoagulation control improves. At a TTR of 70%, warfarin was the preferred treatment in half the iterations. The cost effectiveness of NOACs for stroke prevention in patients with nonvalvular atrial fibrillation who are at increased risk for stroke is highly sensitive to warfarin anticoagulation control. NOACs are more likely to be cost-effective options in settings with poor warfarin management than in settings with better anticoagulation control, where they may not represent good value for money.

    Rodents have interacted with people since the beginning of systematic food storage by humans in the early Neolithic era. Such interactions have had adverse outcomes such as threats to human health, spoiling and consumption of food sources, damage to human infrastructure and detrimental effects on indigenous island wildlife (through inadvertent anthropogenic assisted introductions). These socio/economic and environmental impacts illustrate the clear need to control populations of commensal rodents. Different methods have been applied historically but the main means of control in the last decades is through the application of rodenticides, mainly anticoagulant rodenticides (ARs) that inhibit blood clotting. The so-called First Generation Anticoagulant Rodenticides (FGARs) proved highly effective but rodents increasingly developed resistance. This led to a demand for more effective alternative compounds and paved the way to the development of Second Generation Anticoagulant Rodenticides (SGARs). These were more acutely toxic and persistent, making them more effective but also increasing the risks of exposure of non-target species and secondary poisoning of predatory species. SGARs often fail the environmental thresholds of different regulatory frameworks because of these negative side-effects, but their use is still permitted because of the overwhelming societal needs for rodent control and the lack of effective alternatives. This book provides a state-of-the-art overview of the scientific advancements in assessment of environmental exposure, effects and risks of currently used ARs. This is discussed in relation to the societal needs for rodent control, including risk mitigation and development of alternatives.

    From 1998 to 2006, the Ministry of Public Health of the Republic of Cuba maintained a balanced collaboration with the Social Security Fund (CCSS) of the Republic of Costa Rica with the objective of providing professional services in radiotherapy. As part of the Cuban mission in the 2003-2005 period was conducted clinic design and implementation of a dynamic rotational technique with electron beams for treatment of a neoplastic lesion from the neuro ectoderm early in the first linear accelerator belonging to the CCSS and installed in Hospital Mexico, San Jose. The objective was to achieve locoregional control of the lesion by treatment Radiant surgical bed in the chest wall. We discuss different options settings for the treatment values arch therapy the best choice taking into account the cylindrical geometry of the treatment area and the superficiality of its location. For the determination of the absolute dose used Khan's recommendations. Treatment planning was done following the methodology suggested by Podgorsak et al. We performed a quality control of patient-specific planning and dosimetry in anthropomorphic dummy radiographic, resulting in isodose distribution of very good uniformity in the area of clinical interest. The electron arch therapy technique proved to be superior to alternative proposals for the treatment of superficial lesions with cylindrical symmetry frankly, with regard to dose homogeneity in the target volume and lower dose in critical organs.

    To evaluate the complications and outcome of anticoagulation therapy in pregnant females with valvular heart diseases. All pregnant females with prosthetic heart valves admitted in Armed Forces Institute of Cardiology from Jan 2004 to Dec 2004 were included in this study Basic demographic data including age, duration of pregnancy and complications observed were recorded. Warfarin was replaced with un-fractionated heparin (UFH) in first trimester and after that warfarin was continued with a targeted INR between 2.0-3.0. At 36 weeks warfarin was stopped and UFH was added; however, if patient went into spontaneous labour before this then immediate caesarian section was performed and UFH was restarted 4-6 hours after delivery along with oral warfarin. Out of 21 patients, sixteen (76.1%) had mitral valve diseases and five (23.9%) had both mitral and atrial. Majority (42.3%)of patients were in age group 26-30 years. Eleven (52.2%) reported in 9th month of gestation. Complications observed were hypertension (1), transient ischaemic attacks (1), pulmonary embolism (1), haemoptysis (1) and abortion (1). All patients, except one had successful completion of pregnancy. No case of foetal abnormality was seen. In 76% patients, daily dose of warfarin was <5 mg. Thrombo-prophylaxis in pregnancy with warfarin and UFH with an INR of 2.0-3.0 is effective in preventing thrombotic complications in females with mechanical valves without resulting in increase hemorrhagic complications.

    Direct oral anticoagulants (DOACs) are attractive options for treatment of heparin-induced thrombocytopenia (HIT). We report our continuing experience in Hamilton, ON, Canada, since January 1, 2015 (when we completed our prospective study of rivaroxaban for HIT), using rivaroxaban for serologically confirmed HIT (4Ts score ≥4 points; positive platelet factor 4 [PF4]/heparin immunoassay, positive serotonin-release assay). We also performed a literature review of HIT treatment using DOACs (rivaroxaban, apixaban, dabigatran, edoxaban). We focused on patients who received DOAC therapy for acute HIT as either primary therapy (group A) or secondary therapy (group B; initial treatment using a non-DOAC/non-heparin anticoagulant with transition to a DOAC during HIT-associated thrombocytopenia). Our primary end point was occurrence of objectively documented thrombosis during DOAC therapy for acute HIT. We found that recovery without new, progressive, or recurrent thrombosis occurred in all 10 Hamilton patients with acute HIT treated with rivaroxaban. Data from the literature review plus these new data identified a thrombosis rate of 1 of 46 patients (2.2%; 95% CI, 0.4%-11.3%) in patients treated with rivaroxaban during acute HIT (group A, n = 25; group B, n = 21); major hemorrhage was seen in 0 of 46 patients. Similar outcomes in smaller numbers of patients were observed with apixaban (n = 12) and dabigatran (n = 11). DOACs offer simplified management of selected patients, as illustrated by a case of persisting (autoimmune) HIT (>2-month platelet recovery with inversely parallel waning of serum-induced heparin-independent serotonin release) with successful outpatient rivaroxaban management of HIT-associated thrombosis. Evidence supporting efficacy and safety of DOACs for acute HIT is increasing, with the most experience reported for rivaroxaban. © 2017 by The American Society of Hematology.

    Full Text Available Venous thromboembolism (VTE, consisting of deep vein thrombosis and pulmonary embolism, is a major clinical concern associated with significant morbidity and mortality. The cornerstone of management of VTE is anticoagulation, and traditional anticoagulants include parenteral heparins and oral vitamin K antagonists. Recently, new oral anticoagulant drugs have been developed and licensed, including direct factor Xa inhibitors (e.g. rivaroxaban, apixaban and edoxaban and thrombin inhibitors (e.g. dabigatran etexilate. This narrative review focusses on the characteristics of these direct anticoagulants and the main results of published clinical studies on their use in the prevention and treatment of VTE.

    Anticoagulants-compounds that prevent clotting of the blood-are extensively used for control of small mammal pests. The potential secondary hazards of 6 anticoagulant rodenticides to birds of prey were examined in this study. Whole rats or mice were killed with each anticoagulant and were fed to 1-3 species of owls. Owls died of hemorrhaging after feeding on rats killed with bromadiolone, brodifacoum, or diphacinone; sublethal hemorrhaging occurred in owls fed rats killed with difenacoum. These results demonstrate potential secondary hazards of 4 anticoagulants to avian predators. No abnormalities were observed in owls fed rats killed with fumarin and chlorophacinone

    Radiation treatment to the head and neck and cytotoxic chemotherapy can produce deleterious side effects to the periodontium that are generally transient in nature, reversible, and do not result in permanently visible defects. However, combinations of the malignant disease itself, the direct and indirect effects of medical therapy and associated oral infections, along with local trauma can lead to periodontal tissue destruction with resulting permanent architectural defects. Five case reports illustrate destructive alterations of the periodontium that were associated with oncology therapy. Proposed guidelines for periodontal treatment of compromised individuals undergoing oncology therapies are suggested

    The use of radiation therapy has significantly improved the prognosis of certain brain tumors. However, a few patients have been reported who developed cerebrovasculopathy accompanying transient ischemic attacks several months to several years after radiation therapy. The present report described cerebrovascular disorders after radiation therapy for brain tumors. The first case was an 8-year-6-month-old boy treated with a total dose of 5,200 rads after partial removal of a right periventricular astrocytoma extending into the thalamus. Two years and 7 months after completion of the radiation therapy, he showed transient ischemic attacks of numbness in the right upper limb and right hemiparesis. Arteriography revealed stenosis or occlusion of the anterior and middle cerebral arteries. Preoperative arteriography did not show occlusion nor narrowing of the cerebral arteries. The second case was a 2-year-8-month-old boy diagnosed as diencephalic syndrome, because of marked emaciation and a huge tumor mass expanding into the diencephalon and frontal lobe on the brain CT scan. He was irradiated with up to 5,000 rads. Seven months after radiation therapy, he developed transient right hemiparesis. Arteriography revealed stenosis or occlusion of the middle sized cerebral arteries. Although radiation therapy is acceptable in children with certain brain tumors, and very few patients develop postradiation vasculopathy, the risk of radiation therapy requires more careful consideration in the treatment of intracranial tumors.

    Full Text Available Vitamin K antagonists, such as warfarin, used in oral anticoagulation therapy currently represent the standard drugs for the primary and secondary prevention of stroke in non-valvular atrial fibrillation (AF, with a relative risk reduction close to 70%. Newer oral anticoagulants, such as direct thrombin inhibitors (i.e., dabigatran and direct factor Xa inhibitors (i.e., apixaban and rivaroxaban have been recently compared with warfarin in large randomized trials for stroke prevention in AF. The new oral anticoagulants showed, compared with warfarin, no statistically significant difference in the rate of stroke or systemic embolism in secondary prevention (patients with previous transient ischemic attack or stroke subgroups. With regard to safety, the risk of intracranial bleeding was reduced with new anticoagulants compared with warfarin. Indirect treatment comparisons of clinical trials on secondary prevention cohorts showed no significant difference in efficacy among apixaban, rivaroxaban, and dabigatran; but dabigatran 110 mg was associated with less intracranial bleedings than rivaroxaban.

    Lupus anticoagulant-hypoprothrombinemia syndrome is a rare condition characterized by the association of acquired factor II deficiency and lupus anticoagulant. Contrary to classical antiphospholipid syndrome, it may cause severe life-threatening bleeding (89% of published cases). We report a patient, positive for antidomain I antibodies, with initially primary lupus anticoagulant-hypoprothrombinemia syndrome without previous clinical manifestation or underlying systemic disease. Five years later, he experienced the first systemic lupus erythematous flare. Within a few days, catastrophic antiphospholipid syndrome was diagnosed with heart, liver and kidney involvement. The patient recovered under pulse steroids, intravenous heparin and intravenous immunoglobulins.

    The recent arrival of the target-specific oral anticoagulants (TSOACs) offers potential advantages in the field of anticoagulation. However, there are no rapid and accurate and routinely available laboratory assays to evaluate their contribution to clinical bleeding. With the expanding clinical indications for the TSOACs, and the arrival of newer reversal agents on the market, the emergency clinician will need to be familiar with drug specifics as well as methods for anticoagulation reversal. This review offers a summary of the literature and some practical strategies for the approach to the patient taking TSOACs and the management of bleeding in these cases.

    Selvira Draganović

    2011-01-01

    Full Text Available This paper deals with the emergence and development of feminism in general and feminist psychology with special emphasis on feminist's reaction to traditional assumptions in Freudian psychology and male dominated theory and research. Feminist movement simply started as a women's activism which later claimed political identity and finally ended as women's liberation movement. Feminists simply advocate gender equality. Emergence of feminist psychology movement and appearance of significant female figures in psychology is further explained along with their contribution to the theory, personality and specific developmental issues along with its input to the therapy and counseling field. The influence of four feminist philosophical approaches namely, liberal feminism, cultural feminism, radical feminism and social feminism are also shortly discussed alongside with their practical implications. Above and beyond, feminist contribution to the therapy field reflected in offering specific therapy goals are also discussed. Self esteem as a core issue and one of feminist therapy goals is finally discussed and presented through a specific case study illustration. Feminist therapy is important therapy approach with significant therapy goals contribution in relation to women's mental health issues. Consideration of sex, gender, cultural diversity, etiology, diagnosis and treatment is feminist request for successful therapy because fixing woman for functioning in a dysfunctional society seems not enough.

  16. Oral anticoagulants for stroke prevention in atrial fibrillation.

    Science.gov (United States)

    Senoo, Keitaro; Lane, Deirdre A; Lip, Gregory Y H

    2014-09-01

    The availability of 4 non-vitamin K oral anticoagulants (NOACs), that is, dabigatran, rivaroxaban, apixaban, and edoxaban, has changed the landscape of stroke prevention in patients with atrial fibrillation. This review article provides an overview of the 4 phase III studies that have compared these NOACs, examining major outcomes of efficacy and safety. A range of practical questions relating to the NOACs have emerged, including topics such as patient selection, treating patients with renal impairment, treating elderly patients, and combining anticoagulant therapy with antiplatelet drugs. We also address the interaction of various patient characteristics with the treatments and suggest the features can assist the physician in the choice of a particular NOAC for a particular patient(s).

    Full Text Available Abstract Background Arrhythmias resulting in cardiac arrest during electroconvulsive therapy have been reported. Most reported cases of cardiac arrest had asystole as the initial rhythm. Pulseless electrical activity as an initial rhythm of cardiac arrest during electroconvulsive therapy has never been reported. Also, thromboembolism after inflation of pneumatic tourniquet during lower limb surgery has been reported but never following tourniquet inflation during an electroconvulsive therapy. Case presentation We report a case involving an 81- year- old female who presented to us for an electroconvulsive therapy for severe depression and developed pulseless electrical activity immediately after electroconvulsive therapy. She was successfully resuscitated and was later found to have bilateral pulmonary emboli with a complete occlusion of the right lower lobe pulmonary artery. The source of embolus was from her left lower extremity deep venous thrombus, which we believe, got dislodged intraoperatively after inflation of pneumatic tourniquet. Our patient not only survived the massive pulmonary embolus, but also showed significant improvement in her mental status compared to her pre-admission level at the time of discharge to a sub-acute rehabilitation centre. Conclusion We recommend that patients who are elderly and at high risk of thromboembolism should selectively undergo a preoperative doppler ultrasound for deep venous thrombosis. Also, selective application of tourniquet in the upper limb, to monitor for seizure activity, would reduce the incidence of pulmonary thrombo-embolism as embolic events are significantly less from deep venous thromboses of upper extremities when compared to lower extremities.

    1999-01-01

    Fifteen cases (10 males and 5 females) of neuroblastoma diagnosed by mass screening from November 1993 to October 1997, were observed without therapy. The mean age was 7.9 months. There were tumors in para-aortic area in 4 cases, in adrenal parts in 7 cases, in mediastinum in 3 cases. The other case had tumors in mediastinum and adrenal parts, bilaterally. The observation was executed by the ultrasonography in cases with the abdominal tumor and by MRI in cases with the mediastinal tumor. CT, MRI and US were performed in the first examination by radiologist. MIBG scintigraphy was used mainly for the detection of distant metastases. Imaging was performed at every one or two months in the beginning of observation, and at every three or four months afterwards. Tumors reduced in 9 cases, unchanged in 1 case and increased in 5 cases (8 tumors). The change of tumor size could be evaluated accurately, but the prediction of benignity or malignancy was difficult. Pathological findings were obtained from 5 cases who underwent surgical resection. Four cases had increased tumor. Two of them had benign neuroblastoma or ganglioma, and 2 cases had malignant neuroblastoma of low differentiation. One case with decreased tumor had neuroblastoma and became benign. (K.H.)

    Evaluation of ketogenic diet (KD) therapies for seizure control during pregnancy when safety and appropriate management become considerations. Until now, no information has been available on seizure reduction and human pregnancy related outcomes in women treated with KD therapies. We describe two cases of pregnant women with epilepsy treated with KD therapy either as monotherapy (Case 1) or as adjunctive therapy (Case 2). Case 1: A 27 year old woman, gravida1, started the classic KD with medium chain triglyceride (MCT) emulsion and 75g carbohydrate-restriction, later reduced to 47g. Glucose levels were 4-6mmol/L and blood ketone levels ranged from 0.2 to 1.4mmol/L. Seizure frequency decreased and seizure-free days increased. Mild side effects included intolerance to MCT, reduced serum carnitine and vitamin levels, and mild hyperlipidemia. Fetal and neonatal growth was normal as was growth and development at 12 months. Case 2: A 36 year-old nulliparous woman was treated with a 20 gram carbohydrate-restricted Modified Atkins Diet (MAD) and lamotrigine, resulting in reduction of seizure frequency to once per month prior to pregnancy. Once pregnant, carbohydrates were increased to 30g. When seizures increased, lamotrigine dose was doubled. Urine ketones trended down during second trimester. A male was born with bilateral ear deformities of unknown significance. The child had a normal neurodevelopment at eight months. Non-pharmacological epilepsy therapies like KD and MAD may be effective during human pregnancy. However, safety still has to be established. Further monitoring to identify potential long term side effects is warranted. Copyright © 2017 British Epilepsy Association. All rights reserved.

    The current mainstay of treatment in patients with thrombotic antiphospholipid syndrome (APS) is long-term anticoagulation, mainly with Vitamin K antagonist agents. Some recently available studies have created new ground for discussion about the possible discontinuation of anticoagulation therapy in patients with a history of thrombotic APS in whom antiphospholipid antibodies (aPL) are not detected any longer (i.e. aPL seroconversion). We report the main points discussed at the last CORA Meeting regarding the issue whether or not anticoagulation can be stopped after aPL seroconversion. In particular, we systematically reviewed the available evidence investigating the clinical outcome of APS patients with aPL seroconversion in whom anticoagulation was stopped when compared to those in whom therapy was continued regardless the aPL profile. Furthermore, the molecular basis for the aPL pathogenicity, the available evidence of non-criteria aPL and their association with thrombosis are addressed. To date, available evidence is still limited to support the indication to stop oral anticoagulation therapy in patients with a previous diagnosis of thrombotic APS who subsequently developed a negative aPL profile. The identification of the whole risk profile for cardiovascular manifestations and possibly of a second level aPL testing in selected patients with aPL might support the eventual clinical decision but further investigation is warranted.

    We present a case of psychotic depression presenting with lycanthropy (being converted to a pig) and Cotard syndrome simultaneously and treated with electroconvulsive therapy. A 37-year-old female patient developed psychotic depression after a stressor (a possibility of having a malignancy). As her depression worsened, she developed delusional belief of self being metamorphosed to a pig and her children also being metamorphosed into pig. In addition, she had the delusional belief that her own body and body of her children was rotting away. She was treated with electroconvulsive therapy along with venlafaxine and olanzapine, with which she improved completely.

    Patients with liver disease are at increased risks of both thrombotic and bleeding complications. Many have atrial fibrillation (AF) or venous thromboembolism (VTE) necessitating oral anticoagulant agents (OACs). Recent evidence has contradicted the assumption that patients with liver disease are "auto-anticoagulated" and thus protected from thrombotic events. Warfarin and non-vitamin K-antagonist OACs have been shown to reduce thrombotic events safely in patients with either AF or VTE. However, patients with liver disease have largely been excluded from trials of OACs. Because all currently approved OACs undergo metabolism in the liver, hepatic dysfunction may cause increased bleeding. Thus, the optimal anticoagulation strategy for patients with AF or VTE who have liver disease remains unclear. This review discusses pharmacokinetic and clinical studies evaluating the efficacy and safety of OACs in patients with liver disease and provides a practical, clinically oriented approach to the management of OAC therapy in this population.

    2013-08-01

    The elderly population represents a population at highest risk of thromboembolism, but also the most vulnerable to hemorrhage. In the community setting there is a general tendency to under- treat this patient group. Specific consideration must be taken with elderly patients because they have reduced renal function, co-morbidities and risk of falls, altered pharmacodynamics, and challenges with adherence. Vitamin K antagonists, most often warfarin, have been the first line choice of therapy for long-term anticoagulation and enjoyed an unopposed position in the market for the last 70 years. Recently several new oral anticoagulants have been developed and found to be equally effective as warfarin in phase III studies and may provide an optimal treatment option in the elderly population. In this review we explore the target-specific oral anticoagulants and the pharmacological differences between them with a focus on the elderly population in whom these new drugs would constitute a possible alternative to warfarin therapy.

    2009-01-01

    Full Text Available The present article describes three difficult cases of recurrent bleeding from obscure causes, followed by a review of the pitfalls and pharmacological management of obscure gastrointestinal bleeding. All three patients underwent multiple investigations. An intervening complicating diagnosis or antiplatelet drugs may have compounded long-term bleeding in two of the cases. A bleeding angiodysplasia was confirmed in one case but was aggravated by the need for anticoagulation. After multiple transfusions and several attempts at endoscopic management in some cases, long-acting octreotide was associated with decreased transfusion requirements and increased hemoglobin levels in all three cases, although other factors may have contributed in some. In the third case, however, the addition of low-dose thalidomide stopped bleeding for a period of at least 23 months.

    Meningeal hemangiopericytoma (HPC) is an uncommon dura-based tumor and can recur not only locally but also distantly in the neural axis or extraneural sites. We report our experience of radiation therapy, one preoperative and one elective postoperative, in two patients with meningeal HPC and reviewed the role of radiation therapy. A 41-year-old man (Case 1) presented with a 3-month history of headache and right hemiparesis. The mass was nearly unresectable at the first and second operation and diagnosed as meningeal HPC. Preoperative radiation therapy was given with a total dose of 55.8 Gy/31 fractions to the large residual mass of left frontoparietal area. Follow-up computerized tomography (CT) showed marked regression of tumor after radiation therapy. The third operation was performed to remove the residual tumor at 6 months after the radiation therapy and a 2 x 2 cm sized tumor was encountered. The mass was totally removed. The serial follow-up CT showed no evidence of recurrence and he is alive without distant metastasis for 4 years and 10 months after the first operation. A 45-year-old woman (Case 2) presented with suddenly developed headache and visual impairment. Tumor mass occupying right frontal lobe was removed with the preoperative diagnosis of meningioma. It was totally removed with attached sagittal sinus and diagnosed as meningeal HPC. Elective postoperative radiation therapy was performed to reduce local recurrence with a total dose of 54 Gy/30 fractions to the involved area of right frontal lobe. She is alive for 5 years maintaining normal activity without local recurrence and distant metastasis

    Messer Ben

    2011-01-01

    Full Text Available Abstract This case report describes the first reported overdose of the dihydropyridine calcium channel blocker (CCB lercanidipine. A 49 yr old male presented to the Emergency Department 3 hrs after the ingestion of 560 mg of lercanidipine. In the department he had a witnessed seizure within 15 minutes of arrival attributed to the overdose. Following immediate recovery of consciousness after the seizure, he had refractory hypotension and bradycardia which failed to respond to fluid resuscitation, glucagon therapy, and intravenous calcium. He went on to require vasopressor support with noradrenaline and was treated with high dose insulin therapy which was successful in achieving cardiovascular stability. Vasopressor therapy was no longer required within one half life of lercanidipine, and the total stay on intensive care was one day before transfer to a ward. Calcium channel blocker overdose is an uncommon but life-threatening overdose. Treatment for severe toxicity is similar to b-blocker overdose. Hypotension is treated with intravenous fluid therapy, intravenous calcium and possibly glucagon with vasopressor or inotropic support as required. Atropine is used to attempt reversal of bradycardia. High doses of intravenous insulin with intravenous dextrose as required (hyperinsulinaemic euglycaemia or HIET, has also been successfully reported. Experimental animal data suggests that HIET is of benefit and potentially superior to fluid therapy, calcium, glucagon and potentially vasopressor therapy. HIET effectively and sustainably reverses hypotension, bradycardia and improves myocardial contractility and metabolism. Current advice in calcium channel blocker overdose is to begin therapy early in toxicity, starting with a 1.0 IU/kg insulin bolus followed by an infusion of 0.5 IU/kg/hr of insulin and dextrose as required titrated to clinical response.

    A case is made for why it may now be in the best interest of insurance companies to reimburse for marital therapy to treat marital distress. Relevant literature is reviewed with a considerable focus on the reasons that insurance companies would benefit from reimbursing marital therapy - the high costs of marital distress, the growing link between marital distress and a host of related physical and mental health problems, as well as the availability of empirically supported treatments for marital distress. This is followed by a focus on the major reasons insurance companies cite for not reimbursing marital therapy, along with a discussion of advances in several growing bodies of research to address these concerns. Main arguments include the direct medical offset costs of couple and family therapy (including for high utilizers of health insurance), and the fact that insurance companies already find it cost effective to reimburse for prevention of other health and psychological problems. This is followed by implications for practitioners and researchers. © 2017 American Association for Marriage and Family Therapy.

    There is growing agreement that at least certain kinds of delusions defend against negative self-evaluation, and in consequence that cognitive therapy for delusions needs to address issues of self-evaluation more explicitly. However, in practice it can be difficult to enable clients to see the connection between delusions and self-esteem. The present single-case study exemplifies the conceptual and practical application of cognitive therapy for individuals who are both paranoid and have strong negative self-evaluative beliefs. A multiple-baseline approach is used, whereby one man's negative self-evaluative belief and two paranoid delusions are challenged sequentially. Conviction in two of the three beliefs changes at the point of intervention; conviction in the third changes prior to intervention. We discuss the details of the case, as well as the wider implications for cognitive approaches to delusions.

  18. Impact of INR monitoring, reversal agent use, heparin bridging, and anticoagulant interruption on rebleeding and thromboembolism in acute gastrointestinal bleeding.

    Directory of Open Access Journals (Sweden)

    Naoyoshi Nagata

    Full Text Available Anticoagulant management of acute gastrointestinal bleeding (GIB during the pre-endoscopic period has not been fully addressed in American, European, or Asian guidelines. This study sought to evaluate the risks of rebleeding and thromboembolism in anticoagulated patients with acute GIB.Baseline, endoscopy, and outcome data were reviewed for 314 patients with acute GIB: 157 anticoagulant users and 157 age-, sex-, and important risk-matched non-users. Data were also compared between direct oral anticoagulants (DOACs and warfarin users.Between anticoagulant users and non-users, of whom 70% underwent early endoscopy, no endoscopy-related adverse events or significant differences were found in the rate of endoscopic therapy need, transfusion need, rebleeding, or thromboembolism. Rebleeding was associated with shock, comorbidities, low platelet count and albumin level, and low-dose aspirin use but not HAS-BLED score, any endoscopic results, heparin bridge, or international normalized ratio (INR ≥ 2.5. Risks for thromboembolism were INR ≥ 2.5, difference in onset and pre-endoscopic INR, reversal agent use, and anticoagulant interruption but not CHA2DS2-VASc score, any endoscopic results, or heparin bridge. In patients without reversal agent use, heparin bridge, or anticoagulant interruption, there was only one rebleeding event and no thromboembolic events. Warfarin users had a significantly higher transfusion need than DOACs users.Endoscopy appears to be safe for anticoagulant users with acute GIB compared with non-users. Patient background factors were associated with rebleeding, whereas anticoagulant management factors (e.g. INR correction, reversal agent use, and drug interruption were associated with thromboembolism. Early intervention without reversal agent use, heparin bridge, or anticoagulant interruption may be warranted for acute GIB.

  19. Effective management of venous thromboembolism in the community: non-vitamin K antagonist oral anticoagulants

    Directory of Open Access Journals (Sweden)

    2016-05-01

    Full Text Available Raj Patel Department of Haematological Medicine, King's Thrombosis Centre, King's College Hospital, London, UK Abstract: Anticoagulation therapy is essential for the effective treatment and secondary prevention of venous thromboembolism (VTE. For many years, anticoagulation for acute VTE was limited to the use of initial parenteral heparin, overlapping with and followed by a vitamin K antagonist. Although highly effective, this regimen has several limitations and is particularly challenging when given in an ambulatory setting. Current treatment pathways for most patients with deep-vein thrombosis typically involve initial hospital or community-based ambulatory care with subsequent follow-up in a secondary care setting. With the introduction of non-vitamin K antagonist oral anticoagulants (NOACs into routine clinical practice, it is now possible for the initial acute management of patients with deep-vein thrombosis to be undertaken by primary care. As hospital admissions associated with VTE become shorter, primary care will play an increasingly important role in the long-term management of these patients. Although the NOACs can potentially simplify patient management and improve clinical outcomes, primary care physicians may be less familiar with these new treatments compared with traditional therapy. To assist primary care physicians in further understanding the role of the NOACs, this article outlines the main differences between NOACs and traditional anticoagulation therapy and discusses the benefit–risk profile of the different NOACs in the treatment and secondary prevention of recurrent VTE. Key considerations for the use of NOACs in the primary care setting are highlighted, including dose transition, risk assessment and follow-up, duration of anticoagulant therapy, how to minimize bleeding risks, and the importance of patient education and counseling.

    The European Food Safety Authority (EFSA) asked the Panel on Dietetic Products, Nutrition and Allergies to provide a scientific statement on the safety of glucosamine for patients receiving coumarin anticoagulants. More than 40 case reports have been collected by drug-monitoring agencies...... cases haemorrhage occurred in a variety of organs, and in one case this resulted in a persistent vegetative state. The evidence for an interaction between glucosamine and coumarin anticoagulants is strengthened by the observation that in the majority of cases the INR began to fall to normal values when...... glucosamine intake was discontinued. There is insufficient information to conclude on a mechanism for an interaction between glucosamine and coumarin anticoagulants. There are also insufficient data in the case reports to derive a dose-response relationship for glucosamine and to assess the level of risk...

Baseline characteristics between patients ever-taking or never-taking amiodarone were similar, except more amiodarone patients were smokers (19.5 vs. 6.1%, P = 0.0031). The TTR calculated from 8901international normalized ratios (INRs) in 249 nonamiodarone patients with a mean follow-up of 34 ± 20 months (mean INR 36 ± 18) was 66 ± 16.6% compared with 61.3 ± 16.2% (P = 0.111) from 1455 INRs in 41 amiodarone-treated patients with a mean follow-up of 28 ± 20 months (mean INR 35 ± 22). Factors associated with a low TTR were male sex (P = 0.0013), smoker (P = 0.0048), and amiodarone use (P = 0.0374). A second on-treatment analysis, in which the TTR was calculated only during amiodarone therapy, resulted in similar findings; however, amiodarone did not emerge as a predictor of a low TTR. In 11 patients, the TTR prior to amiodarone (54.5 ± 22.2%) was not significantly different in the first 3 months (54.6 ± 33.4%) or after 3 months (67.2 ± 33.7%) of amiodarone. In a single high-quality anticoagulation center, anticoagulation quality, as measured by the TTR, can be comparable in amiodarone and nonamiodarone-treated patients.

    Thyrotoxicosis and well differentiated thyroid carcinomas are the two most common pathological conditions where radioiodine is used. Patients with well differentiated thyroid carcinomas are the candidates for post operative radio iodine therapy. It is currently the most popular and frequently used method of treatment. Its use is safe and cost effective. The results are usually eventless but in some exceptional cases emergencies that occurred after administration of I-131. One emergency occurred after I-131 administration for Graves' disease and the second case happened after therapeutic application of I-131 for treatment of local recurrences of thyroid cancer.(author)

    On the 4 cases of operation for the late radiation effect, the process and notes for radiation colitis were described. Case 1; a female of 57 y with cervical carcinoma (IIIb) received 59.8 Gy of external irradiation and 24.0 Gy of intracervical irradiation. About 8 months after the radiotherapy, anemia due to gut bleeding was observed and hemorrhage was seen in the colon with the colon fiber. One year later, colostomy was performed. Case 2; a female of 79 y with cervical carcinoma (IIb) received 50.0 Gy of external irradiation and 18.0 Gy of intracervical irradiation. About 8 months after the therapy, gut bleeding and ileac symptom were observed and ulcer and stenosis in the sigmoid colon were seen. Sigmoidectomy was performed. Case 3; a female of 75 y with cervical carcinoma (IIIb) received external 49.8 Gy irradiation and intracervical 23.0 Gy irradiation. About 4 months after the therapy, anemia and ulcer with hemorrhage in the sigmoidal colon were recognized. Sigmoidectomy and colostomy were performed. Case 4; a female of 68 y with cervical carcinoma (IIb) and chronic renal failure received 50.4 Gy of external irradiation post hysterectomy. About 5 months later, iliac symptom was observed. She received ileectomy and then colostomy but died of MOF due to renal failure. (K.H.)

    The integration of evidence into reflective health care practice has been on the rise in recent years and is a phenomenon that has affected all health care professions, including massage therapy. Clinical case studies are a research design that follows one patient or subject, making the studies ideal for use in clinical practice. They are valuable for communicating information from clinical practice to the broader community. Case studies have face validity that may be more valuable to individual practitioners than homogeneous randomized controlled trials, as the practitioner may recognize a complex patient in the case report. At Humber College, Student Massage Therapists (SMTs) create, conduct, and communicate results of a clinical case study prior to graduation. This article describes the process and experience.

    Iliopsoas haematoma is a rare complication that occurs in patients receiving anticoagulant therapy. The clinical manifestation of iliopsoas haematoma is non-specific. It can mimic orthopaedic or neurological disorders, including paraesthesia or paresis of the thigh and leg due to compression of the nerve plexus. Among the many available diagnostic modalities, computed tomography is the most useful radiological method for diagnosis. Treatment approaches for iliopsoas haematoma include conservative therapy, surgical intervention, or transcatheter arterial embolisation. Conservative therapy consists of bed rest, restoration of circulating volume, and drug discontinuation for correcting underlying coagulopathy. Although a conservative approach is the first choice, transcatheter arterial embolisation and surgical intervention may be required in patients with hemodynamically unstable and active bleeding. The report described a case of iliopsoas haematoma due to anticoagulant therapy with paraesthesia in the left leg who was successfully treated by conservative approach. (author)

    The hippocampus is responsible for memory and cognitive function. An ongoing phase II clinical trial suggests that sparing dose to the hippocampus during whole-brain radiation therapy can help preserve a patient's neurocognitive function. Progressive research and advancements in treatment techniques have made treatment planning more sophisticated but beneficial for patients undergoing treatment. The aim of this study is to evaluate and compare hippocampal sparing whole-brain (HS-WB) radiation therapy treatment planning techniques using volume-modulated arc therapy (VMAT) and intensity-modulated radiation therapy (IMRT). We randomly selected 3 patients to compare different treatment techniques that could be used for reducing dose to the hippocampal region. We created 2 treatment plans, a VMAT and an IMRT, from each patient's data set and planned on the Eclipse 11.0 treatment planning system (TPS). A total of 6 plans (3 IMRT and 3 VMAT) were created and evaluated for this case study. The physician contoured the hippocampus as per the Radiation Therapy Oncology Group (RTOG) 0933 protocol atlas. The organs at risk (OR) were contoured and evaluated for the plan comparison, which included the spinal cord, optic chiasm, the right and left eyes, lenses, and optic nerves. Both treatment plans produced adequate coverage on the planning target volume (PTV) while significantly reducing dose to the hippocampal region. The VMAT treatment plans produced a more homogenous dose distribution throughout the PTV while decreasing the maximum point dose to the target. However, both treatment techniques demonstrated hippocampal sparing when irradiating the whole brain.

  12. Graves’ Disease and Treatment Effects on Warfarin Anticoagulation

    Directory of Open Access Journals (Sweden)

    Amanda Howard-Thompson

    2014-01-01

    Full Text Available Background. Hyperthyroidism causes an increased hypoprothrombinemic response to warfarin anticoagulation. Previous studies have demonstrated that patients with hyperthyroidism require lower dosages of warfarin to achieve a therapeutic effect. As hyperthyroidism is treated and euthyroidism is approached, patients may require increasing warfarin dosages to maintain appropriate anticoagulation. We describe a patient’s varying response to warfarin during treatment of Graves’ disease. Case Presentation. A 48-year-old African American female presented to the emergency room with tachycardia, new onset bilateral lower extremity edema, gradual weight loss, palpable goiter, and generalized sweating over the prior 4 months. She was admitted with Graves’ disease and new onset atrial fibrillation. Primary stroke prophylaxis was started using warfarin; the patient developed a markedly supratherapeutic INR likely due to hyperthyroidism. After starting methimazole, her free thyroxine approached euthyroid levels and the INR became subtherapeutic. She remained subtherapeutic over several months despite steadily increasing dosages of warfarin. Immediately following thyroid radioablation and discontinuation of methimazole, the patient’s warfarin dose and INR stabilized. Conclusion. Clinicians should expect an increased response to warfarin in patients with hyperthyroidism and close monitoring of the INR is imperative to prevent adverse effects. As patients approach euthyroidism, insufficient anticoagulation is likely without vigilant follow-up, INR monitoring, and increasing warfarin dosages.

    2001-04-01

    Full Text Available Abstract Background Why waiting lists arise and how to address them remains unclear, and an improved understanding of these waiting list "dynamics" could lead to better management. The purpose of this study is to understand how the current shortage in radiation therapy in Ontario developed; the implications of prolonged waits; who is held accountable for managing such delays; and short, intermediate, and long-term solutions. Methods A case study of the radiation therapy shortage in 1998-99 at Princess Margaret Hospital, Toronto, Ontario, Canada. Relevant documents were collected; semi-structured, face-to-face interviews with ten administrators, health care workers, and patients were conducted, audio-taped and transcribed; and relevant meetings were observed. Results The radiation therapy shortage arose from a complex interplay of factors including: rising cancer incidence rates; broadening indications for radiation therapy; human resources management issues; government funding decisions; and responsiveness to previous planning recommendations. Implications of delays include poorer cancer control rates; patient suffering; and strained doctor-patient relationships. An incompatible relationship exists between moral responsibility, borne by government, and legal liability, borne by physicians. Short-term solutions include re-referral to centers with available resources; long-term solutions include training and recruiting health care workers, improving workload standards, increasing compensation, and making changes to the funding formula. Conclusion Human resource planning plays a critical role in the causes and solutions of waiting lists. Waiting lists have harsh implications for patients. Accountability relationships require realignment.

    Objective: To study the imaging features of nutcracker syndrome (compression of left renal vein), and to assess the value of the interventional therapy for this disease. Methods: The clinical data of 6 cases of nutcracker syndrome undertaken interventional therapy were collected to analyze the clinical features, imaging characteristics and interventional therapeutic value together with comprehensive literatures. Results: The imaging appearance of the 6 cases showed typical left renal vein compression. The average in between angle of superior mesenteric artery(SMA)and abdominal aorta(At)was 20.6 degree ± 4.04 degree in MPR reconstructed imaging of CTA. The blood pressure gradient between proximal and distal compression sites was(6.4 ± 0.36) cmH 2 O. No complications of displacement and defluxion and restenosis occurred after stenting for a year. The subjective symptoms of the 6 patients improved significantly. Conclusion: Endovascular stenting is a safe, mini-traumatic and effective therapy for nutcracker syndrome. (authors)

    Gc protein-derived macrophage-activating factor (GcMAF) occurs naturally in the human body. It has various functions, such as macrophage activation and antitumor activities. Recently, immunotherapy has become an attractive new strategy in the treatment of cancer. GcMAF-based immunotherapy can be combined with many other therapies. Sonodynamic therapy (SDT) using low-intensity ultrasound is a novel therapeutic modality. Ultrasound has been demonstrated to activate a number of sonosensitive agents allowing for the possibility of non-invasive targeted treatment for both superficial and deep-seated tumors. The current case study demonstrates that GcMAF and SDT can be used in combination with conventional therapies in patients with metastatic cancer, especially where treatment options are limited due to factors such as toxicity. This case study also suggests a new concept of cancer treatment using local destruction of cancer tissue, in this case conducted with SDT, to be used in combination with GcMAF immunotherapy as a systemic treatment.

    Full Text Available A group of oral anticoagulant-treated patients affected by permanent atrial fibrillation was evaluated after their access to the emergency room as a result of a traumatic accident. In these patients, the re-evaluation of their risk of thromboembolism and bleeding was performed together with the evaluation of their risk of falling and institutionalization. Results show that the emergency department identifies a cohort of very elderly frail patients, who should be carefully reconsidered for anticoagulant therapy after a traumatic event.

    Non-vitamin K antagonist oral anticoagulants (NOACs, dabigatran, rivaroxaban, apixaban, and edoxaban) have been increasingly used as alternatives to warfarin for stroke prophylaxis in patients with atrial fibrillation. Yet there is substantial lack of information on how patients on NOACs are currently treated when they have an acute ischemic stroke and the best strategies for treating intracerebral hemorrhage for those on chronic anticoagulation with warfarin or a NOAC. These are critical unmet needs for real world clinical decision making in these emergent patients. The ARAMIS Registry is a multicenter cohort study of acute stroke patients who were taking chronic anticoagulation therapy prior to admission and are admitted with either an acute ischemic stroke or intracerebral hemorrhage. Built upon the existing infrastructure of American Heart Association/American Stroke Association Get With the Guidelines Stroke, the ARAMIS Registry will enroll a total of approximately 10,000 patients (5000 with acute ischemic stroke who are taking a NOAC and 5000 with anticoagulation-related intracerebral hemorrhage who are on warfarin or a NOAC). The primary goals of the ARAMIS Registry are to provide a comprehensive picture of current treatment patterns and outcomes of acute ischemic stroke patients on NOACs, as well as anticoagulation-related intracerebral hemorrhage in patients on either warfarin or NOACs. Beyond characterizing the index hospitalization, up to 2500 patients (1250 ischemic stroke and 1250 intracerebral hemorrhage) who survive to discharge will be enrolled in an optional follow-up sub-study and interviewed at 3 and 6 months after discharge to assess longitudinal medication use, downstream care, functional status, and patient-reported outcomes. The ARAMIS Registry will document the current state of management of NOAC treated patients with acute ischemic stroke as well as contemporary care and outcome of anticoagulation-related intracerebral hemorrhage.

    Two groups of patients were observed for evidence of acute radiation hepatitis during high dose radiation to the liver. The first group of 18 patients with metastatic liver disease received an average of 4,050 rad to the whole liver. Half received anticoagulation with warfarin. One patient on anticoagulation developed evidence of acute radiation hepatitis while 2 patients did so without anticoagulation. Eleven patients with Hodgkin's disease received 4,000 rad to the left lobe of the liver during extended field radiation. Four of these 11 patients were anticoagulated to therapeutic range. Only one of the fully anticoagulated patients showed changes on liver scan consistent with radiation hepatitis whereas three did so without anticoagulation. No serious sequelae from anticoagulation occurred in either group. These preliminary data suggest that anticoagulation may be safely administered with high dose hepatic radiation and that further trials with anticoagulation are warranted

    Occupational therapy practitioners frequently identify opportunities for international practice. The World Health Organization and the World Federation of Occupational Therapists have encouraged occupational therapists to address transnational issues, social inclusion, and equal access to opportunities grounded in meaningful occupation (WFOT, 2012). This case study describes a partnership between two U.S. schools of occupational therapy and a Cuban community based pediatric clinic. It examines the dynamics that have sustained the partnership despite political, economic, and logistical barriers. The literature is scrutinized to show how this case study fits into other accounts of collaborative international partnerships. Particularly, it investigates structural and institutional conditions that shape international sustainable partnerships. In doing so, we answer the following questions: (1) Under which circumstances do international partnerships emerge and flourish? (2) What structural and institutional conditions shape international sustainable partnerships? And (3) How do partners perceive and experience the bilateral international partnership? It also discusses and illustrates the foundations and development of international partnerships that succeed. Through the use of a case study we illustrate the development of this partnership. Finally, we consider the next steps of this particular sustainable and collaborative international partnership. © 2015 John Wiley & Sons, Ltd.

    Insomnia is one of the most common complaints faced by primary care practitioners after pain. Non-pharmacological management of Insomnia that is noninvasive is gaining interest among patients with insomnia. To determine the feasibility of recruiting and retaining participants in a clinical trial on shirodhara, Ayurvedic oil dripping therapy, for insomnia in the United States and also to investigate the therapeutic usefulness of Shirodhara for insomnia using standardized outcome measures. Case series. Shirodhara with Brahmi oil was done for 45 minutes on each participant for 5 consecutive days. Insomnia Severity Index (ISI) was used to evaluate the severity of insomnia as well as to determine the response to Shirodhara therapy. Data were collected at baseline, end of the treatment (day 5) and 1 week after the treatment ended (follow-up). Two males and eight females with a mean age of 40 years (range 23 to 72), SD ± 14.2, were enrolled in the study. One dropped out of the study, but all remaining nine participants experienced improvement at the end of treatment. The percentage of improvement range varied from 3.85% to 69.57%. At follow-up, most participants continued to improve. Comparison of means between baseline and day 5 indicated an overall significant improvement (P insomnia. It is feasible to recruit and retain participants for such therapies in the United States. It is important to validate these findings and investigate the mechanism of action using a larger sample and rigorous research design.

    Science.gov (United States)

    Berger, J.

    1992-01-01

    ROENTGEN is a design assistant for radiation therapy planning which uses case-based reasoning, an artificial intelligence technique. It learns both from specific problem-solving experiences and from direct instruction from the user. The first sort of learning is the normal case-based method of storing problem solutions so that they can be reused. The second sort is necessary because ROENTGEN does not, initially, have an internal model of the physics of its problem domain. This dependence on explicit user instruction brings to the forefront representational questions regarding indexing, failure definition, failure explanation and repair. This paper presents the techniques used by ROENTGEN in its knowledge acquisition and design activities. PMID:1482869

    In this case study, a young women who has chronic verbal, emotional, and physical abuse and was exposed to repetitive adult acts of abuse as a child initially presented with Posttraumatic Stress Disorder (PTSD) marked by constriction and disconnection, which resulted in her feeling passive and tortured. As part of her occupational therapy intervention, based on the occupational adaptation, psychoanalytic, and recovery frames of reference, she was able to use her skills as a musician and lyricist to work through her trauma by performing heavy metal music. She used work to express emotions and tell and retell her story to audiences eager to hear her. Work helped her develop an identity that allowed her to be active in the world and reach out to others through her music. This case study focuses on the intervention - how music and occupation functioned as a foundation for relieving her PTSD.

    2002-01-01

    The major goal of this research case study was to investigate the effectiveness of Virtual Reality Therapy (VRT) in the treatment of the fear of public speaking. A twenty-eight-year-old Caucasian male was selected from questionnaires distributed to a class of undergraduate students enrolled at Kennesaw State University. Two assessment measures were used in this study. The first measure used was the Attitude Towards Public Speaking (ATPS) Questionnaire. The second measure used was the eleven-point Subjective Units of Disturbance (SUD) scale. These measurements assessed the anxiety, avoidance, attitudes and disturbance associated with the subject's fear of public speaking before and after each VRT treatment session. This case study of public speaking fear indicates that VRT may be used as an effective treatment method for reducing self-reported anxiety.

    Monitoring oral anticoagulants is logistically challenging for both patients and medical staff. We evaluated the effect of adding an interactive voice response system to computerized decision support for oral anticoagulant management. We developed an interactive voice response system to communicate to patients the results of international normalized ratio testing and their dosage schedules for anticoagulation therapy. The system also reminded patients of upcoming and missed appointments for blood tests. We recruited patients whose anticoagulation control was stable after at least 3 months of warfarin therapy. We prospectively examined clinical data and outcomes for these patients for an intervention period of at least 3 months. We also collected retrospective data for each patient for the 3 months before study enrolment. We recruited 226 patients between Nov. 23, 2006, and Aug. 1, 2007. The mean duration of the intervention period (prospective data collection) was 4.2 months. Anticoagulation control was similar for the periods during and preceding the intervention (mean time within the therapeutic range 80.3%, 95% confidence interval [CI] 77.5% to 83.1% v. 79.9%, 95% CI 77.3% to 82.6%). The interactive voice response system delivered 1211 (77.8%) of 1557 scheduled dosage messages, with no further input required from clinic staff. The most common reason for clinic staff having to deliver the remaining messages (accounting for 143 [9.2%] of all messages) was an international normalized ratio that was excessively high or low, (i.e., 0.5 or more outside the therapeutic range). When given the option, 76.6% of patients (164/214) chose to continue with the interactive voice response system for management of their anticoagulation after the study was completed. The system reduced staff workload for monitoring anticoagulation therapy by 48 min/wk, a 33% reduction from the baseline of 2.4 hours. Interactive voice response systems have a potential role in improving the

Progressive research and advancements in treatment techniques have made treatment planning more sophisticated but beneficial for patients undergoing treatment. The aim of this study is to evaluate and compare hippocampal sparing whole-brain (HS-WB) radiation therapy treatment planning techniques using volume-modulated arc therapy (VMAT) and intensity-modulated radiation therapy (IMRT). We randomly selected 3 patients to compare different treatment techniques that could be used for reducing dose to the hippocampal region. We created 2 treatment plans, a VMAT and an IMRT, from each patient's data set and planned on the Eclipse 11.0 treatment planning system (TPS). A total of 6 plans (3 IMRT and 3 VMAT) were created and evaluated for this case study. The physician contoured the hippocampus as per the Radiation Therapy Oncology Group (RTOG) 0933 protocol atlas. The organs at risk (OR) were contoured and evaluated for the plan comparison, which included the spinal cord, optic chiasm, the right and left eyes, lenses, and optic nerves. Both treatment plans produced adequate coverage on the planning target volume (PTV) while significantly reducing dose to the hippocampal region. The VMAT treatment plans produced a more homogenous dose distribution throughout the PTV while decreasing the maximum point dose to the target. However, both treatment techniques demonstrated hippocampal sparing when irradiating the whole brain.

    Direct oral anticoagulants (DOACs) have expanded the armamentarium for antithrombotic therapy. Although DOAC-related major bleeding was associated with favorable outcomes compared with warfarin in clinical trials, warfarin effects were reversed in bleeding events. Red blood cell transfusions occurred more often in DOAC bleeding events than in warfarin events (52.0% vs 39.5%; adjusted relative risk [aRR], 1.32; 95% CI, 1.19-2.47). However, units of blood products transfused were not different between the two groups. Thirty-four DOAC cases (7.4%) received activated prothrombin complex concentrates or recombinant factor VIIa. In-hospital mortality was lower following DOAC bleeding events (9.8% vs 15.2%; aRR, 0.66; 95% CI, 0.49-0.89), although differences in 30-day mortality did not reach statistical significance (12.6% vs 16.3%; aRR, 0.79; 95% CI, 0.61-1.03). In this unselected cohort of patients with oral anticoagulant-related hemorrhage with high rates of warfarin reversal, in-hospital mortality was lower among DOAC-associated bleeding events. These findings support the safety of DOACs in routine care and present useful baseline measures for evaluations of DOAC-specific reversal agents. Copyright © 2017 The Authors.

  10. Assessing Bleeding Risk in Patients Taking Anticoagulants

    2013-01-01

    Anticoagulant medications are commonly used for the prevention and treatment of thromboembolism. Although highly effective, they are also associated with significant bleeding risks. Numerous individual clinical factors have been linked to an increased risk of hemorrhage, including older age, anemia, and renal disease. To help quantify hemorrhage risk for individual patients, a number of clinical risk prediction tools have been developed. These risk prediction tools differ in how they were derived and how they identify and weight individual risk factors. At present, their ability to effective predict anticoagulant-associated hemorrhage remains modest. Use of risk prediction tools to estimate bleeding in clinical practice is most influential when applied to patients at the lower spectrum of thromboembolic risk, when the risk of hemorrhage will more strongly affect clinical decisions about anticoagulation. Using risk tools may also help counsel and inform patients about their potential risk for hemorrhage while on anticoagulants, and can identify patients who might benefit from more careful management of anticoagulation.

    We observed the outbreak time of a spinal compression fracture following radiation therapy and its natural course. Case 1 was a 88-year-old, woman. NTX 66.9. Underwent cobalt irradiation 54 Gy for esophageal cancer. Three months after irradiation, the first lumbar vertebra was found to de compressed, and low back pain occurred. Vacuum cleft phenomenon in X-P appeared after two weeks, but anterior callus formation appeared in eight weeks, after which the low back pain disappeared. Case 2 was a 77-year-old woman. NTX 86.5. Underwent irradiation 69 Gy for uterine carcinoma. Six months after the irradiation, the fourth/five lumbar vertebra were found to be compressed. Great collapse occurred in X-P after two weeks, but stabilized and did not aggravate thereafter. Low back pain also disappeared. Radiotherapy affects bone cells (osteoblasts, osteoclasts), inhibiting bone remodeling. As a result, deficient elastic resistance occurs. Vertebral bodies are also compressed in such a situation. After that normal callus formation starts from adjacent normal bone cells. The compression fracture observed ranged from three to six months after radiation. Natural course is well. Therefore conservative therapy is recommended. (author)

    Postpartum depression can have devastating consequences on the mother and child. Prompt treatment is challenging. Whereas electroconvulsive therapy (ECT) is considered to be an effective treatment modality in severe depression and brings about rapid clinical improvement, little is known about ECT during the postpartum period. We systematically reviewed the literature on the use of ECT during the postpartum period using PubMed, Institute for Scientific Information Web of Knowledge and PsycINFO databases until September 2014, using the search terms "electroconvulsive therapy" or "ECT" and "postpartum". Then, we described the successful treatment with ECT and the joint mother-baby hospitalization of a woman with severe depression. Eight case reports and 8 studies were identified. All of the studies reported that ECT is effective in the postpartum period. It is well tolerated, provides a fast response and allows for breastfeeding. In addition, our case report showed the benefits of the hospitalization of the mother-baby unit. Combined ECT and joint mother-baby hospitalization could be a valuable treatment by targeting both the mother-infant relationship and the maternal depressive symptoms. Copyright © 2015 Elsevier Inc.

    Full Text Available Antiphospholipid syndrome (APS is an autoimmune disease characterised by arterial and/or venous thrombosis, recurrent pregnancy loss, and persistently positive antiphospholipid antibodies (aPLs. It could be life-threatening as in the case of catastrophic APS where multi-organ failure is observed. APS morbidities are thought to be the result of a combination of thrombotic and inflammatory processes. Over the past decades, the mainstay of therapy of APS has been anticoagulation. As new mechanisms of pathogenesis are being unravelled with time, novel targeted immunomodulatory therapies are being proposed as promising agents in the treatment of APS. In this article, we present an overview of new pathogenetic mechanisms in APS as well as novel antithrombotic and immunomodulatory therapies.

    Full Text Available Objectives Unipolar depression (UPD is a leading cause of global burden of diseases, particularly among the elderly, whose treatment may be challenging. In such cases, ECT is often recommended due to its safety and efficacy. This report presents a case of a 67-year-old male inpatient that developed a rare cardiac complication during ECT. Methods Clinical case report with patient’s consent and bibliographic review. Results A 67-year-old male inpatient with recurrent severe psychotic depression was hospitalized and ECT was indicated after failure of the pharmacological treatment. A comprehensive clinical pre-evaluation revealed only nonspecific ST-segment changes in electrocardiogram. During the 7th ECT session, it was observed transitory ST-segment depression followed by a discrete increase of plasma troponin I. Severe tri-vessel coronary artery stenosis was found and a percutaneous coronary angioplasty was performed, with satisfactory psychiatric and cardiac outcomes. Conclusions Unipolar depression (UPD and cardiovascular disease are often coexistent conditions, especially among the elderly. In the current case, myocardial ischemia was detected lately during ECT therapy and its treatment allowed the UPD treatment to be completed adequately.

    Full Text Available Abstract Introduction Sertraline and Risperidone are commonly used psychotropic drugs. Sertraline has previously been associated with eosinopilic pneumonia. Neither drug is recognised as a cause of diffuse fibrotic lung disease. Our report represents the first such case. Case Presentation We describe the case of a 33 year old Asian male with chronic schizophrenia who had been treated for three years with sertraline and risperidone. He presented to hospital in respiratory failure following a six month history of progressive breathlessness. High resolution CT scan demonstrated diffuse pulmonary fibrosis admixed with patchy areas of consolidation. Because the aetiology of this man's diffuse parenchymal lung disease remained unclear a surgical lung biopsy was undertaken. Histological assessment disclosed widespread fibrosis with marked eosinophillic infiltration and associated organising pneumonia - features all highly suggestive of drug induced lung disease. Following withdrawal of both sertraline and risperidone and initiation of corticosteroid therapy the patient's respiratory failure resolved and three years later he remains well albeit limited by breathlessness on heavy exertion. Conclusion Drug induced lung disease can be rapidly progressive and if drug exposure continues may result in respiratory failure and death. Prompt recognition is critical as drug withdrawal may result in marked resolution of disease. This case highlights sertraline and risperidone as drugs that may, in susceptible individuals, cause diffuse pulmonary fibrosis.

    The introduction of point-of-care devices for the management of patients on oral anticoagulation allows self-testing by the patient at home. Patients who self-test can either adjust their medication according to a pre-determined dose-INR (international normalized ratio) schedule (self-management), or they can call a clinic to be told the appropriate dose adjustment (self-monitoring). Increasing evidence suggests self-testing of oral anticoagulant therapy is equal to or better than standard monitoring. This is an updated version of the original review published in 2010. To evaluate the effects on thrombotic events, major haemorrhages, and all-cause mortality of self-monitoring or self-management of oral anticoagulant therapy compared to standard monitoring. For this review update, we re-ran the searches of the Cochrane Central Register of Controlled Trials (CENTRAL), 2015, Issue 6, the Cochrane Library, MEDLINE (Ovid, 1946 to June week 4 2015), Embase (Ovid, 1980 to 2015 week 27) on 1 July 2015. We checked bibliographies and contacted manufacturers and authors of relevant studies. We did not apply any language restrictions . Outcomes analysed were thromboembolic events, mortality, major haemorrhage, minor haemorrhage, tests in therapeutic range, frequency of testing, and feasibility of self-monitoring and self-management. Review authors independently extracted data and we used a fixed-effect model with the Mantzel-Haenzel method to calculate the pooled risk ratio (RR) and Peto's method to verify the results for uncommon outcomes. We examined heterogeneity amongst studies with the Chi(2) and I(2) statistics and used GRADE methodology to assess the quality of evidence. We identified 28 randomised trials including 8950 participants (newly incorporated in this update: 10 trials including 4227 participants). The overall quality of the evidence was generally low to moderate. Pooled estimates showed a reduction in thromboembolic events (RR 0.58, 95% CI 0.45 to 0

  19. Reversal of target-specific oral anticoagulants

    Siegal, D.M.; Cuker, Adam

    2014-01-01

    Target-specific oral anticoagulants (TSOACs) provide safe and effective anticoagulation for the prevention and treatment of thrombosis in a variety of clinical settings by interfering with the activity of thrombin (dabigatran) or factor Xa (rivaroxaban, apixaban, edoxaban, betrixaban). Although TSOACs have practical advantages over vitamin K antagonists (VKAs), there are currently no antidotes to reverse their anticoagulant effect. Herein we summarize the available evidence for TSOAC reversal using nonspecific and specific reversal agents. We discuss important limitations of existing evidence, which is derived from studies in human volunteers, animal models and in vitro experiments. Studies evaluating the safety and efficacy of reversal agents on clinical outcomes such as bleeding and mortality in patients with TSOAC-associated bleeding are needed. PMID:24880102

    To determine the efficacy of investigating hematuria in anticoagulated patients the authors examined records of 25 consecutive patients with hematuria who were on an anticoagulation regimen with sodium warfarin (Coumadin) for various thromboembolic disorders. All had undergone intravenous urography (IVU) and 12 had undergone cystoscopy. Potential bleeding sources were discovered in 14 patients by IVU and in seven patients by cystoscopy. Disorders found were renal stones (4), transitional carcinoma (1), lymphoma (1), retroperitoneal hematoma (1), bladder tumors (2), calcified renal mass (1), hemorrhagic cystitis (2), and enlarged prostate (7). In 18 (72%) patients, the findings on IVU and/or cystoscopy were abnormal. Hematuria is a serious symptom that warrants investigation in anticoagulated as well as nonanticoagulated patients

    We present a case of pineal apoplexy in an anticoagulated and hypertensive 56-year-old Hispanic male. At presentation, the patient's international normalized ratio (INR) was 10.51 and his blood pressure was 200/130 mmHg. His presenting symptoms included acute onset of headache, chest pain, nausea, vomiting, vertigo, and visual disturbance. Neuroimaging demonstrated hemorrhage into a morphologically normal pineal gland. Under conservative management, the patient experienced gradual resolution of all symptoms excluding the disturbance of upward gaze.

    Full Text Available Abstract Background The most common causes of hemotympanum are therapeutic nasal packing, epistaxis, blood disorders and blunt trauma to the head. Hemotympanum is characterized as idiopathic, when it is detected in the presence of chronic otitis media. A rare case of spontaneous bilateral hemotympanum in a patient treated with anticoagulants is presented herein. Case presentation A 72-year-old male presented with acute deterioration of hearing. In the patient's medical history aortic valve replacement 1 year before presentation was reported. Since then he had been administered regularly coumarinic anticoagulants, with INR levels maintained between 3.4 and 4.0. Otoscopy revealed the presence of bilateral hemotympanum. The audiogram showed symmetrical moderately severe mixed hearing loss bilaterally, with the conductive component predominating. Tympanograms were flat bilaterally with absent acoustic reflexes. A computerized tomography scan showed the presence of fluid in the mastoid and middle ear bilaterally. Treatment was conservative and consisted of a 10-day course of antibiotics, anticongestants and temporary interruption of the anticoagulant therapy. After 3 weeks, normal tympanic membranes were found and hearing had returned to previous levels. Conclusion Anticoagulant intake should be included in the differential diagnosis of hemotympanum, because its detection and appropriate treatment may lead to resolution of the disorder.

    Leeches (Annelida: Hirudinea) possess powerful salivary anticoagulants and, accordingly, are frequently employed in modern, authoritative medicine. Members of the almost exclusively marine family Piscicolidae account for 20% of leech species diversity, and feed on host groups (e.g., sharks) not encountered by their freshwater and terrestrial counterparts. Moreover, some species of Ozobranchidae feed on endangered marine turtles and have been implicated as potential vectors for the tumor-associated turtle herpesvirus. In spite of their ecological importance and unique host associations, there is a distinct paucity of data regarding the salivary transcriptomes of either of these families. Using next generation sequencing, we profiled transcribed, putative anticoagulants and other salivary bioactive compounds that have previously been linked to bloodfeeding from 7 piscicolid species (3 elasmobranch-feeders; 4 non-cartilaginous fish-feeders) and 1 ozobranchid species (2 samples). In total, 149 putative anticoagulants and bioactive loci were discovered in varying constellations throughout the different samples. The putative anticoagulants showed a broad spectrum of described antagonistic pathways, such as inhibition of factor Xa and platelet aggregation, that likely have similar bioactive roles in marine fish and turtles. A transcript with homology to ohanin, originally isolated from king cobras, was found in Cystobranchus vividus but is otherwise unknown from leeches. Estimation of selection pressures for the putative anticoagulants recovered evidence for both positive and purifying selection along several isolated branches in the gene trees and positive selection was also estimated for a few select codons in a variety of marine species. Similarly, phylogenetic analyses of the amino acid sequences for several anticoagulants indicated divergent evolution.

    To explore the correlative factors and clinical characteristics of digestive system injury during the treatment of anticoagulant and (or) antiplatelet-agents. A total of 1 443 hospitalized patients on anticoagulant and (or) antiplatelet-agents from January 2010 to December 2013 at Renmin Hospital of Wuhan University were analyzed retrospectively. Their length of hospital stay was from 5 to 27 days. Most of them were elderly males (n = 880, 61.0%) with an average age of (62 ± 6) years. 1 138 patients (78.9%) were farmers, workers or someone without a specific occupation. During the treatment of anticoagulant/antiplatelet-agents, statistical difference existed (P = 0.01) between positively and negatively previous digestive disease groups for actively newly occurring digestive system injury (16.0% (41/256) vs 15.9% (189/1 187)). After the dosing of anticoagulant and (or) antiplatelet-agents, 57 (66.3%, 57/86) patients were complicated by hemorrhage of digestive tract, taking 62.9% (61/97) of all positive result patients for Helicobacter pylori test. Comparing preventive PPI group with no PPI group, there was no marked statistical differences (P = 2.67) for digestive system complication (including hemorrhage of digestive tract) while receiving anticoagulant and (or) antiplatelet-agents (13.9% (74/533) vs 17.1% (156/910)). During anticoagulant and/or antiplatelet-agent therapy, 185 patients (12.8%) were complicated by peptic ulcer or peptic ulcer with bleeding, 40 patients (2.8%) had erosive gastritis and 5 (0.3%) developed acute gastric mucosal lesions. And 42 of 76 patients complicated by hemorrhage of digestive tract underwent endoscopic hemostasis while 2 patients were operated. Ninety-seven patients (6.7%) died, including 61 (62.9%, 61/97) from hemorrhage of digestive tract. The remainder became cured, improved and discharged. Moreover, no significant statistical differences existed (P = 2.29) among three combination group (aspirin, clopidogrel, warfarin), two

  5. Glucocorticoid augmentation of prolonged exposure therapy: rationale and case report

    Full Text Available Rationale: Prolonged exposure (PE therapy has been found to reduce symptoms of posttraumatic stress disorder (PTSD; however, it is difficult for many patients to engage fully in the obligatory retelling of their traumatic experiences. This problem is compounded by the fact that habituation and cognitive restructuring – the main mechanisms through which PE is hypothesized to work – are not instantaneous processes, and often require several weeks before the distress associated with imaginal exposure abates. Case reports: Two cases are described that respectively illustrate the use of hydrocortisone and placebo, in combination with PE, for the treatment of combat-related PTSD. Based on known effects of glucocorticoids on learning and memory performance, we hypothesized that augmentation with hydrocortisone would improve the therapeutic effects of PE by hastening “new” learning and facilitating decreases in the emotional impact of fear memories during the course of treatment. The veteran receiving hydrocortisone augmentation of PE displayed an accelerated and ultimately greater decline in PTSD symptoms than the veteran receiving placebo. Conclusions: While no general conclusion can be derived from comparison of two patients, the findings are consistent with the rationale for augmentation. These case reports support the potential for an appropriately designed and powered clinical trial to examine the efficacy of glucocorticoids in augmenting the effects of psychotherapy for PTSD.

    Full Text Available Much research supports the everyday therapeutic and deeper socialneurophysiological influence of singing songs alone and in groups (Austin, 2008; Cozolino, 2013; Sacks, 2007. This study looks at what happens when Japanese students teach short English affirmation songlet-routines to others out of the classroom (clandestine folk music therapy. I investigate 155 student-conducted musical case studies from 7 semester-long classes (18 to 29 students per class over a 4-year period. The assignments, their in-class training, and their results are introduced, with examples directly from their case studies. Each class published their own booklet of case studies (a class publication, available to readers online for research replication and modeling. Results show that most primary participants enjoyed spreading these positive songlets as they became “well-becoming agents of change” in their own social networks. “Well-becoming” emphasizes an agentive action or activity that creates better well-being in others, an action such as the sharing or teaching of a songlet. The qualitative data reveals a number of types of well-becoming such as social and familial bonding, meaning-making, teaching-rushes, and experiencing embodied cognition. The project also stimulated wider network dissemination of these well-becoming possibilities and pedagogical insights.

    The Audit and Guidelines Committee of the European Association for Cardio-Thoracic Surgery recently published a guideline on antiplatelet and anticoagulation management in cardiac surgery. We aimed to assess the awareness of the current guideline and adherence to it in the National Health Service through this National Audit. We designed a questionnaire consisting of nine questions covering various aspects of antiplatelet and anticoagulation management in post-cardiac surgery patients. A telephonic survey of the on-call cardiothoracic registrars in all the cardiothoracic centres across the UK was performed. All 37 National Health Service hospitals in the UK with 242 consultants providing adult cardiac surgical service were contacted. Twenty (54%) hospitals had a unit protocol for antiplatelet and anticoagulation management in post-cardiac surgery. Only 23 (62.2%) registrars were aware of current European Association for Cardio-Thoracic Surgery guidelines. Antiplatelet therapy is variable in the cardiac surgical units across the country. Low-dose aspirin is commonly used despite the recommendation of 150-300 mg. The loading dose of aspirin within 24 h as recommended by the guideline is followed only by 60.7% of surgeons. There was not much deviation from the guideline with respect to the anticoagulation therapy.

    A Japanese female in her 60's on 5 years' treatment with prednisolone 5 mg for ulcetarive colitis developed severe bloody stools and diarrhea and was admitted. A total colectomy was performed because leukocytapheresis with intravenous corticosteroid administration (prednisolone 70 mg/day) relieved her symptoms partially. Pneumocystis pneumonia (PCP) prophylaxis was not introduced then. She developed acute respiratory failure on postoperative day (POD) 8, and was intubated and moved to our intensive care unit. PCP was suspected and sulfamethoxazole/trimethoprim (ST) was started with methylprednisolone 40 mg/day. The pneumonia initially improved but got worse around POD 27 and pulse corticosteroid therapy was administered. Antibiotics were first changed to pentamidine and finally changed to clindamycin/primaquine because of adverse reactions due to both of the medications. She recovered fully and experienced no exacerbation after discontinuation of the secondary prophylaxis. This is the first report of primaquine administration for PCP in Japan. Clindamycin/primaquine are second-line drugs but very important because the first-line medications such as ST and pentamidine cause adverse reactions and frequently result in discontinuation, as was the case in our present patient. Nowadays immunosuppresive therapy for malingnancies and autoimmune diseases has been introduced more frequently than before, PCP has attracted more attention. Therefore primaquine should be approved for appropriate use without delay in Japan.

    Multimodal cancer therapy for pediatric head and neck tumors may be associated with significant developmental orofacial morbidity. This report details these effects in a child (C.I.) diagnosed at 2.5 years of age with a rhabdomyosarcoma, primary to the left buccinator. This case is of interest as C.I. has an unaffected identical twin (D.I.) for comparative study. Both were assessed by comparing panoramic radiographs and lateral and frontal tracings of cephalometric radiographs obtained at 8.25 years of age. C.I. had multiple dental anomalies which included agenesis, ectopia, crown malformation, and root malformation. Root malformation, ectopia, and agenesis were restricted to the left dentition, whereas crown malformation was noted bilaterally. C.I. had a generalized craniofacial skeletal hypoplasia relative to D.I. in all three planes, growth defects were greater on the side of the tumor, and the mandible was affected more than the nasomaxillary complex

    Physical therapists (PTs) frequently provide neuromusculoskeletal treatment for patients who incidentally may have one or more tattoos. Low level light therapy (LLLT) is one of the modalities commonly used by physical therapists to decrease pain and facilitate healing. This case report describes a 22 year old man who was given LLLT to address his complaints of musculoskeletal pain. Blistering of the skin was documented over the LLLT application site, a black tattoo. The blisters, which formed after the LLLT treatment were most likely caused by the inadvertent and unexpected heating of the iron oxides and/or the metal salts in the tattoo's black pigment. PTs should exercise caution when applying LLLT in the presence of dark tattoos. Copyright © 2016 Elsevier Ltd. All rights reserved.

    The complete elimination of bacteria inside the root canal is a difficult task, and inconsistent removal of the innermost layer of contaminated dentin leaves bacteria behind. PDT is an adjunct to conventional endodontic treatment due to its potential to reduce bacteria and its biocompatibility. Report a case of endodontic treatment associated with Photodynamic Therapy (PDT). A patient with chronic dentoalveolar abscess with radiolucent lesion next to the apexes of teeth 11 and 21 was submitted to conventional endodontic treatment associated with PDT. The canals were filled after two PDT sessions with an interval of 15days between applications. After six months, total regression of apical periodontitis and no fistula or associated symptoms were observed. The treatment proposed is a viable option for the clinician as it is easy to perform, has relatively low-cost and allows the improvement of symptoms in a short period of time.

    Objectives This cross-sectional survey explored the characteristics and outcomes of direct oral anticoagulant (DOAC)–associated nontraumatic intracerebral hemorrhages (ICHs) by analyzing a large nationwide Japanese discharge database. Methods We analyzed data from 2,245 patients who experienced ICHs while taking anticoagulants (DOAC: 227; warfarin: 2,018) and were urgently hospitalized at 621 institutions in Japan between April 2010 and March 2015. We compared the DOAC- and warfarin-treated patients based on their backgrounds, ICH severities, antiplatelet therapies at admission, hematoma removal surgeries, reversal agents, mortality rates, and modified Rankin Scale scores at discharge. Results DOAC-associated ICHs were less likely to cause moderately or severely impaired consciousness (DOAC-associated ICHs: 31.3%; warfarin-associated ICHs: 39.4%; p = 0.002) or require surgical removal (DOAC-associated ICHs: 5.3%; warfarin-associated ICHs: 9.9%; p = 0.024) in the univariate analysis. Propensity score analysis revealed that patients with DOAC-associated ICHs also exhibited lower mortality rates within 1 day (odds ratio [OR] 4.96, p = 0.005), within 7 days (OR 2.29, p = 0.037), and during hospitalization (OR 1.96, p = 0.039). Conclusions This nationwide study revealed that DOAC-treated patients had less severe ICHs and lower mortality rates than did warfarin-treated patients, probably due to milder hemorrhages at admission and lower hematoma expansion frequencies.

    Cervical artery dissection is a common cause of stroke in young adults. This may result from head and neck trauma; it can also occur spontaneously or secondary to genetic connective tissue or vascular disorders. Neurologic symptoms arise as a result of thromboembolism and hypoperfusion causing cerebral ischemia. We present a case of a previously healthy male who was found to have a cervical internal carotid artery dissection and the decision to use antiplatelet therapy instead of anticoagulation to prevent stroke. Data is lacking regarding the efficacy of one therapy over the other.

    Full Text Available OBJECTIVE: to study the changes in health-related quality of life from beginning of anticoagulation therapy to six-month follow-up, and to study associations of sociodemographic and clinical characteristics with measures of quality of life and general health status at six-month follow-up, in individuals using oral anticoagulation due to various medical indications for the therapy. METHOD: prospective study performed at a city in the state of Paraná, Brazil, composed of 78 patients. Measures included the Duke Anticoagulation Satisfaction Scale and the Medical Outcomes Survey Short Form SF-36. RESULTS: mean age was 57 years (S.D.= 16 and 54% were women. Compared to the beginning of therapy, there was a statistically significant improvement in health-related quality of life at six-month follow-up. Linear regression analyses explained 32% and 30%, respectively, of the variance of the Duke Anticoagulation Satisfaction Scale and of the general health status. There was improvement in all components of the SF-36, except Mental Health. CONCLUSION: The use of oral anticoagulation therapy was associated with improvement in health-related quality of life in the first six months of therapy. This study is longitudinal and therefore, has fewer limitations than cross-sectional studies published to date in the Nursing literature in Brazil.OBJETIVO: Estudiar los cambios en la calidad de vida relacionada con la salud desde el inicio de la anticoagulación oral y al final de seis meses de tratamiento, y estudiar las asociaciones de las características sociodemográficas y clínicas con las medidas de calidad de vida y salud general seis meses después de iniciar la terapia, en pacientes con diversas indicaciones clínicas de anticoagulación oral.

    Despite several therapeutic possibilities the morbidity and mortality of thromboembolic disorders remain high. Improving drug compliance - i. e. keeping up the doctor's prescriptions - may be an effective tool to reach better results. To improve patients' compliance, the risk factors of non-compliance should be recognized. Among these patients' fear of adverse effects of drugs, their lack of knowledge about their illness and medication, forgetfulness, and other social, economic factors may be the most important. Furthermore, adherence may be worsened when the patient feels that the decision has been made over his/her head. Sustained medical adherence is important because anticoagulation may be a life-long treatment. The new oral anticoagulants make the matter of compliance to be current. These new type of drugs do not need regular laboratory monitoring and, therefore, compliance cannot be strictly followed. There are several studies concerning drug compliance to anticoagulant medications. Improvement of adherence is based on regular patient education after reviewing the factors of non-compliance, which needs teamwork with important roles of doctors, pharmacists, dietetics and nurses. Careful and accurate work of the participants of primary care might be complemented by the activity of anticoagulant clinics.

    Full Text Available Abstracts: Objective: To summarize the use rate, safety, efficacy of antithrombotics in stroke/transient ischemic attack (TIA prevention, and reasons for not using dabigatran etexilate (DE in Shanghai, China. Methods: Non-valvular atrial fibrillation (NVAF-associated stroke patients were prospectively registered as an electronic database. Use rate of antithrombotics and reasons for not using DE were extracted during follow-up. Patients' baseline characteristics, recurrent ischemic stroke/TIA events and bleeding complications were analyzed. Patients: From April 2012 to August 2014, 110 inpatients with NVAF-associated stroke were studied in our hospital. NVAF was diagnosed by 12-lead electrocardiogram, 24 h Holter and echocardiography. Results: Before introduction of DE (April 2013, use rates of warfarin and antiplatelets were 28.9% (11/38 and 60.5% (23/38 respectively; after that, use rates of warfarin, DE, and antiplatelets were 20.8% (15/72, 12.5% (9/72, and 43.1% (31/72. The DE did not improve use of anticoagulants (P = 0.639. There were 19 (17.3% recurrent ischemic stroke events up to October 2015; two (9.5% in the non-user group, 10 (18.5% in the antiplatelet group, and seven (20.0% in the anticoagulants group (P = 0.570. Furthermore, recurrence rates were similar between the DE group (20.0% and the Warfarin group (20.0%, P = 1.000. The most common reason for not using DE was financial concerns (61.0%, followed by inconvenience to purchase (14.0% and hemorrhage concerns (11.0%. Two patients using warfarin found fecal occult blood so they stopped warfarin and began to use antiplatelet drugs. No bleeding event occurred in the other groups. Only one patient had side effects (dyspepsia and gastroesophageal reflux from DE. Conclusion: The use rate of either DE or warfarin in Shanghai was low; DE had not improved anticoagulation therapy for NVAF patients in Shanghai mainly because DE had not been covered by health insurance.

    Until recently, warfarin, clopidogrel and aspirin have provided the mainstay for prevention of thrombotic disease in cardiac patients. However, new classes of drugs have recently emerged that promise better clinical outcomes and lower risks. Use of such agents has increased, but increased risk and severity of intra-cranial haemorrhage (ICH) still remain. These cases of intra-cranial bleeds present as emergencies to neurosurgical units. It is of paramount importance that neurosurgical practitioners are aware of those new drugs, useful monitoring tests and available emergency reversal options in case the patient needs emergency intervention. In this review we survey newly available agents in the U.K. at the time of publication. We look at the data provided by the manufacturers, related publications and international guidelines for their use and reversal. New anticoagulants offer a lower incidence of ICH compared with warfarin. Advanced and accurate monitoring tests are emerging, as are prospective data on reversal of anticoagulation in bleeding. Some standard coagulation tests may be of use, whilst reversal agents are available and being evaluated. The trial data shows that new antiplatelet agents have similar or increased incidence and severity of intra-cranial ICH compared with clopidogrel. There is currently limited data on monitoring or reversal. We suggest they may be managed similarly to clopidogrel by using platelet reactivity assays, optimising platelet count and using platelet transfusion with adjunctive agents.

    To assess prescribing of anticoagulants in atrial fibrillation (AF) in the elderly, both a quantitative point of view (rate of anticoagulation) and qualitative (type of anticoagulation). Determinants of prescribing and non-prescribing were also analysed. Prospective survey of practice, based on one clinical case and questionnaire conducted in 60 practitioners (20 cardiologists [C], 20 geriatricians [G] and 20 general practitioners [GP]). In reading the clinical case, 88.3% of physicians would have initiated a treatment; three types of treatments would have been chosen: AVK (68.3%), ODA (20.0%) and platelet antiaggregant (11.7%). Criteria taken into account to initiate anticoagulation varied according to the specialty. Cardiologists considered more the age criteria (C: 95.0%, G: 75.0%, MG: 60.0%; PC: 90.0%, G: 60.0%, MG: 55.0%; PC: 85.0%, G: 55.0%, MG: 60.0%; PC: 80.0%, G: 35.0%, MG: 25.0%; PC: 15.0%, G: 5.0%, MG: 0.0%; PC: 35.0%, G: 5.0%, MG: 45.0%; PC: 70.0%, G: 75.0%, MG: 85.0%; P<0.05). This survey confirms that the FA remains under anticoagulated in the elderly and the barriers to the prescription of oral anticoagulation are often without rational basis.

    Background There is a lower reported incidence of intracranial hemorrhage with non-vitamin K antagonist oral anticoagulants compared with vitamin K antagonist. However, the functional outcome and mortality of intracranial hemorrhage patients were not assessed. Aims To compare the outcome of vitamin K antagonists- and non-vitamin K antagonist oral anticoagulants-related intracranial hemorrhage. Methods We included consecutive patients with acute non-traumatic intracranial hemorrhage on oral anticoagulation therapy admitted between January 2013 and June 2015 at four university hospitals. Clinical and demographic data were obtained from individual medical records. Intracranial hemorrhage was classified as intracerebral, extra-axial, or multifocal using brain computed tomography. Three-month functional outcome was assessed using the modified Rankin Scale. Results Among 246 patients included, 24 (9.8%) were anticoagulated with a non-vitamin K antagonist oral anticoagulants and 222 (90.2%) with a vitamin K antagonists. Non-vitamin K antagonist oral anticoagulants patients were older (81.5 vs. 76 years, p = 0.048) and had intracerebral hemorrhage more often (83.3% vs. 63.1%, p = 0.048). We detected a non-significant trend for larger intracerebral hemorrhage volumes in vitamin K antagonists patients ( p = 0.368). Survival analysis adjusted for age, CHA 2 DS 2 VASc, HAS-BLED, and anticoagulation reversal revealed that non-vitamin K antagonist oral anticoagulants did not influence three-month mortality (hazard ratio (HR) = 0.83, 95% confidence interval (CI) = 0.39-1.80, p = 0.638). Multivariable ordinal regression for three-month functional outcome did not show a significant shift of modified Rankin Scale scores in non-vitamin K antagonist oral anticoagulants patients (odds ratio (OR) 1.26, 95%CI 0.55-2.87, p = 0.585). Conclusions We detected no significant differences in the three-month outcome between non-vitamin K antagonist oral anticoagulants

    Current guidelines recommend triple antithrombotic therapy (TAT), defined as acetylsalicylic acid (ASA), clopidogrel, and warfarin, for patients with nonvalvular atrial fibrillation who have undergone percutaneous coronary intervention with stent implantation. The choice of anticoagulant/antiplatelet therapy in this population is ambiguous and complex, and prescribing patterns are not well documented. To characterize local prescribing patterns for anticoagulant/antiplatelet therapy after percutaneous coronary intervention in patients with nonvalvular atrial fibrillation. A chart review was conducted at a single quaternary cardiology centre. Patients with nonvalvular atrial fibrillation were identified via medical records, and those who underwent percutaneous coronary intervention were identified using a local clinical patient registry. Adult inpatients with nonvalvular atrial fibrillation and a CHADS2 score (based on congestive heart failure, hypertension, age ≥ 75 years, diabetes mellitus, prior stroke) of 1 or higher who underwent percutaneous coronary intervention from 2011 to 2013 were included. Patients undergoing cardiovascular surgery or transcatheter aortic valve replacement, those with mechanical devices requiring anticoagulation, and those with an allergy to any component of TAT were excluded. Seventy patients were included. The median age was 75 years, and 52 (74%) were men. At discharge, 30 (43%) were receiving TAT and 27 (39%) were receiving dual antiplatelet therapy (clopidogrel and ASA). No patients received the combination of warfarin and clopidogrel. Among those who received TAT, 90% (19 of 21) who received a bare metal stent had a recommended duration of 1 month, and 75% (6 of 8) who received a drug-eluting stent had a recommended duration of 1 year. Direct-acting oral anticoagulants with 2 antiplatelet drugs were prescribed for 9% (6 of 70) of the patients, and 10% (7 of 70) received ticagrelor and ASA with or without warfarin. Overall, the

    Full Text Available Background: Asthma is an inflammatory clutter of the airways that causes wheezing, breathlessness, chest tightness, and coughing. In India, approximate calculation indicates a prevalence of between 10% and 15% in 5-11 year old children. Modern Western treatment focuses on controlling asthma with two classes of medication corticosteroids and bronchodilatorss. Another plan of action for reducing and potentially even throw out asthma manifestation affects manipulation of the craniosacral fascial system. This system is a unification of the craniosacral and fascial or connective tissue part. This idea can help in making clear the greatly high rate of achievement with manual therapy in pediatric asthma. Methods: In this case report first I have taken a brief history of the patient condition after the full assessment like brain cycle rhythm, chest and systemic. I have given cranio sacral therapy, Intercostal release, PNF for diaphragm release on child for seven sitting of about 45 minutes of each session. Results: After completion of treatment session of seven sitting his lungs to be bright of any wheezing or other impediment. Brain cycle was of 90 seconds. His peak flow meter readings were between 250 and 300 Liters/minute, which were in a satisfactory range for him. The physician suggested that at this point there was no requirement for any additional asthma medicines. Conclusion: It comes into sight that the loss to the respiratory system caused by fascial burden early in life may be fully reversible, if treated immediately. The latent grace of this interdependent approach is that it crop up to address the pathological origin of asthma.

  10. Combined administration of antibiotics and direct oral anticoagulants: a renewed indication for laboratory monitoring?

    Science.gov (United States)

    2014-10-01

    The recent development and marketing of novel direct oral anticoagulants (DOACs) represents a paradigm shift in the management of patients requiring long-term anticoagulation. The advantages of these compounds over traditional therapy with vitamin K antagonists include a reportedly lower risk of severe hemorrhages and the limited need for laboratory measurements. However, there are several scenarios in which testing should be applied. The potential for drug-to-drug interaction is one plausible but currently underrecognized indication for laboratory assessment of the anticoagulant effect of DOACs. In particular, substantial concern has been raised during Phase I studies regarding the potential interaction of these drugs with some antibiotics, especially those that interplay with permeability glycoprotein (P-gp) and cytochrome 3A4 (CYP3A4). A specific electronic search on clinical trials published so far confirms that clarithromycin and rifampicin significantly impair the bioavailability of dabigatran, whereas clarithromycin, erythromycin, fluconazole, and ketoconazole alter the metabolism of rivaroxaban in vivo. Because of their more recent development, no published data were found for apixaban and edoxaban, or for potential interactions of DOACs with other and widely used antibiotics. It is noteworthy, however, that an online resource based on Food and Drug Administration and social media information, reports several hemorrhagic and thrombotic events in patients simultaneously taking dabigatran and some commonly used antibiotics such as amoxicillin, cephalosporin, and metronidazole. According to these reports, the administration of antibiotics in patients undergoing therapy with DOACs would seem to require accurate evaluation as to whether dose adjustments (personalized or antibiotic class driven) of the anticoagulant drug may be advisable. This might be facilitated by direct laboratory assessments of their anticoagulant effect ex vivo. Thieme Medical Publishers

    The aim of this study was to evaluate the internal reliability and validity of the Brazilian-Portuguese version of Duke Anticoagulation Satisfaction Scale (DASS) among cardiovascular patients. Oral anticoagulation is widely used to prevent and treat thromboembolic events in several conditions, especially in cardiovascular diseases; however, this therapy can induce dissatisfaction and reduce the quality of life. Methodological and cross-sectional research design. The cultural adaptation of the DASS included the translation and back-translation, discussions with healthcare professionals and patients to ensure conceptual equivalence, semantic evaluation and instrument pretest. The Brazilian-Portuguese version of the DASS was tested among subjects followed in a university hospital anticoagulation outpatient clinic. The psychometric properties were assessed by construct validity (convergent, known groups and dimensionality) and internal consistency/reliability (Cronbach's alpha). A total of 180 subjects under oral anticoagulation formed the baseline validation population. DASS total score and SF-36 domain correlations were moderate for General health (r=-0.47, pDASS score and most of the subscales, except Limitation (r=-0.375, pscale, and it ranged from 0.76 (hassles and burdens)-0.46 (psychological impact) among the domains, confirming the internal consistency reliability. The Brazilian-Portuguese version of the DASS has shown levels of reliability and validity comparable with the original English version. Healthcare practitioners and researchers need internationally validated measurement tools to compare outcomes of interventions in clinical management and research tools in oral anticoagulation therapy. © 2011 Blackwell Publishing Ltd.

    2012-01-01

    Full Text Available Non-neoplastic portal vein thrombosis (PVT is an increasingly recognized complication of liver cirrhosis. It is often diagnosed fortuitously and can be either partial or complete. The clinical significance of PVT is not obvious except in some situations such as when patients are on the waiting list for liver transplantation. The only known therapy is anticoagulation which has been shown to permit the disappearance of thrombosis and to prevent further extension. Anticoagulation is a challenging therapy in individuals with liver cirrhosis because of the well-recognized coagulation abnormalities observed in that setting and because of the increased risk of bleeding, especially from gastrointestinal tract caused by portal hypertension. We herein review the current knowledge on that topic in order to highlight the advantages and disadvantages of the currently proposed therapeutic attitudes in face of the diagnosis of PVT in individuals with cirrhosis.

  15. Acute kidney injury aggravated by treatment initiation with apixaban: Another twist of anticoagulant-related nephropathy

    2017-12-01

    Full Text Available Anticoagulant-related nephropathy (ARN was initially described in patients on warfarin (as warfarin-related nephropathy and recently in those using dabigatran. Herein, we report clinical history and kidney biopsy findings in a patient on apixaban (Eliquis. Initiation of treatment with apixaban resulted in aggravation of preexisting mild acute kidney injury (AKI. A few days after apixaban therapy, the patient became oligoanuric, and kidney biopsy showed severe acute tubular necrosis with numerous occlusive red blood cell casts. Only one out of 68 glomeruli with open capillary loops had small segmental cellular crescent. Therefore, there was major discrepancy between the degree of glomerular injury and the glomerular hematuria. Considering that the onset of this AKI was associated with apixaban treatment initiation, we propose that this patient had ARN associated with factor Xa inhibitor (apixaban, which has not previously been described. Monitoring of kidney function is recommended after initiation of anticoagulant therapy.

    Full Text Available Abstract Introduction Various surgical procedures are available to correct paralytic ectropion, which are applied in irreversible facial paresis. Problems occur when facial paresis has an unclear prognosis, since surgery of the lower eyelid is usually irreversible. We propose a simple method to correct temporary ectropion in facial palsy by applying an adhesive strip. Patients and methods Ten patients with peripheral facial paresis and paralytic ectropion were treated with an adhesive strip to correct paralytic ectropion. We used "Steri-Strips" (45 × 6.0 mm, which were taped on the carefully cleaned skin of the lower eyelid and of the adjacent zygomatic region until the prognosis of the paresis was clarified. In addition to the examiner's evaluation of the lower lacrimal point in the lacrimal lake, subjective improvement of the symptoms was assessed using a visual analogue scale (VAS, 1–10. Results 9 patients reported a clear improvement of the symptoms after adhesive taping. There was a clear regression of tearing (VAS (median = 8; 1 = no improvement, 10 = very good improvement, the cosmetic impairment of the adhesive tape was low (VAS (median = 2.5; 1 = no impairment, 10 = severe impairment and most of the patients found the use of the adhesive strip helpful. There was slight reddening of the skin in one case and well tolerated by the facial skin in the other cases. Conclusion The cause and location of facial nerve damage are decisive for the type of surgical therapy. In potentially reversible facial paresis, procedures should be used that are easily performed and above all reversible without complications. Until a reliable prognosis of the paresis can be made, adhesive taping is suited for the temporary treatment of paralytic ectropion. Adhesive taping is simple and can be performed by the patient.

    Evaluation of therapeutic results and of the efficacy and effectiveness of treatments is an area of interest both for clinicians and researchers. In general, randomized controlled trial designs have been used as the methodology of choice in which intergroup comparisons are made having a minimum of participants in each arm of treatment. However, these procedures are seldom used in daily clinical practice. Despite this fact, the evaluation of treatment results for a specific patient is important for the clinician in order to address if therapeutic goals have been accomplished both in terms of statistical significance and clinical meaningfulness. The methodology based on the reliable change index (Jacobson y Truax)1 provides an estimate of these two criteria. The goal of this article is to propose a procedure to apply the methodology with a single case study of a woman diagnosed with major depression and treated with electroconvulsive therapy.

    Immune thrombocytopenia (ITP) is a hematological disorder with an isolated decrease in number of circulating platelets. Bee venom therapy (BVT) is a form of alternative medicine. It is still being practiced in the Middle East and other parts of Asia. In BVT, acupuncture points are used to inject diluted bee venom into the body. The pharmacological basis behind BVT is not fully understood. However, it has been used to treat various medical conditions such as arthritis and low back pain. On the other hand there have been a number of reported complications of BVT use such as ITP. We present a case report on ITP after BVT. A 61 year old lady presented with gum bleeding and ecchymosis and found to have isolated thrombocytopenia (platelet count of 9 × 10(9)/L) after receiving four direct bee sting sessions. There was no evidence of any other risk factors of ITP. Bee venom components and toxicity may be associated with thrombocytopenia as a complication. Further research is needed to postulate guidelines and protocol for BVT. In the meantime, monitoring of the practice of BVT should be made, with an emphasis on patient education regarding the safety profile and associated risks compared to the gained benefits.

    Our objective was to describe our experience of managing a cohort of adult patients prescribed direct oral anticoagulants (DOACs) undergoing dentoalveolar procedures between November 2012 and May 2016. Prior to conducting a procedure a formal assessment was made of each patient's anticoagulation treatment. A specific plan was then formulated, balancing the risk of bleeding with the risk of thrombosis. Patients received a telephone consultation one week following treatment to assess any post-operative bleeding. Eighty-two patients underwent 111 oral surgical procedures, the majority of which were dental extractions. In the case of 35 (32%) procedures, advice was given to omit the DOAC, either before or after treatment. There was no bleeding following the majority of procedures. Persistent bleeding followed 15 (13.5%) procedures, of which 7 (6.3%) procedures required specific intervention. The majority of patients prescribed DOACs can undergo dentoalveolar procedures safely. Important considerations when planning treatment are: (i) when the patient usually takes their dose of DOAC, (ii) the time the procedure is performed and, (iii) when the DOAC is taken post-procedure. In our experience, if these factors are considered carefully, omission of DOAC doses is unlikely to be required for most patients.

    2004-02-01

    Full Text Available Fucan is a term used to denote a family of sulfated L-fucose-rich polysaccharides which are present in the extracellular matrix of brown seaweed and in the egg jelly coat of sea urchins. Plant fucans have several biological activities, including anticoagulant and antithrombotic, related to the structural and chemical composition of polysaccharides. We have extracted sulfated polysaccharides from the brown seaweed Dictyota menstrualis by proteolytic digestion, followed by separation into 5 fractions by sequential acetone precipitation. Gel electrophoresis using 0.05 M 1,3-diaminopropane-acetate buffer, pH 9.0, stained with 0.1% toluidine blue, showed the presence of sulfated polysaccharides in all fractions. The chemical analyses demonstrated that all fractions are composed mainly of fucose, xylose, galactose, uronic acid, and sulfate. The anticoagulant activity of these heterofucans was determined by activated partial thromboplastin time (APTT using citrate normal human plasma. Only the fucans F1.0v and F1.5v showed anticoagulant activity. To prolong the coagulation time to double the baseline value in the APTT, the required concentration of fucan F1.0v (20 µg/ml was only 4.88-fold higher than that of the low molecular weight heparin Clexane® (4.1 µg/ml, whereas 80 µg/ml fucan 1.5 was needed to obtain the same effect. For both fucans this effect was abolished by desulfation. These polymers are composed of fucose, xylose, uronic acid, galactose, and sulfate at molar ratios of 1.0:0.8:0.7:0.8:0.4 and 1.0:0.3:0.4:1.5:1.3, respectively. This is the fist report indicating the presence of a heterofucan with higher anticoagulant activity from brown seaweed.

  2. Direct oral anticoagulants: what can we learn?

    Marongiu, Francesco; Barcellona, Doris

    2018-03-02

    Direct oral anticoagulants (DOACs) represent an innovation because they avoid periodic laboratory monitoring, and also reduce cerebral bleeding. An examination of the performance of DOACs versus warfarin in randomized clinical trials dedicated to atrial fibrillation would reveal the poor performance of warfarin because the percentage of major bleeding is always above 3%; however, the percentage of major bleeding is less than half of that when the management is done in anticoagulation clinics (ACs). Several years ago, a common opinion was that ACs would disappear as soon as DOACs enter the market. We proposed then that ACs could be transformed into thrombosis centres (TCs) because we envisaged many new activities in terms of diagnostic tools and therapeutic choices. After the introduction of DOACs, the role of the ACs has been re-evaluated because their role may be crucial in selecting both the most appropriate diagnostic approach and the best therapeutic option (including anti-vitamin K drugs) for the single patient. TCs can organize a regular follow-up to improve patient adherence to DOACs. Marketing might have a role in the decision making of the single doctor. Efforts should be made for limiting the relationships between doctors and pharmaceutical companies. It seems reasonable to better prepare doctors, during their university courses, for them to develop a greater scientific culture that would enable them to critically read clinical studies and acquire an independent opinion. Ideally, an expert in haemostasis and thrombosis should handle new and old anticoagulants.

    Full Text Available Chronic subdural hematoma (CSDH is common squeal of trauma and rarely associated with anticoagulant therapy, antiplatelet, chemotherapeutic drugs, arteriovenous malformation, aneurysms and post-craniotomy. However its occurrence is very unusual with systemic haematological malignancy and mostly reported with acute myeloid leukemia; however incidence of SDH occurrence in chronic myelogenous leukemia (CML is very rare. CML is a haematological malignancy characterized by chromosomal alteration, pathologically represents increased proliferation of the granulocytic cell line without loss of capacity to differentiate. CML has three phases - remission phase, accelerated phase and blast crisis. About 85 % of patients present in remission phase of disease and carries a favorable prognosis. As intracranial, subdural hematoma usually occur in the accelerated phase or blast crisis phase or extremely uncommon during chronic remission phase, although only those affected, who are neglecting therapeutic medication or discontinued therapy or rarely as an adverse effect of medications. However, important role of neurosurgeon lies in early detection and correction of platelet count and associated hematological abnormality as quite sizeable proportion of cases may not need surgical intervention instead can be managed conservatively under regular supervision in association with oncologist colleague, but few cases may need urgent surgical intervention. So, selecting a subgroup of CML cases in the remission phase requiring surgical intervention, presenting with CSDH is not only challenging, as failure to make an informed and timely precise decision can lead to catastrophic worse outcome and even mortality. So, purpose of current article is to formulate the management therapeutic plan. Authors report three cases of CML in chronic remission phase, receiving treatment under guidance of Haemto-oncologist at our institute presented with spontaneous chronic SDH. The mean

    Psychogenic amnesia is widely understood to be a memory impairment of psychological origin that occurs as a response to severe stress. However, there is a paucity of evidence regarding the effectiveness of psychological therapy approaches in the treatment of this disorder. The current article describes a single case, "Ben", who was treated with formulation-driven psychological therapy using techniques drawn from cognitive behavioural therapy (CBT) and acceptance and commitment therapy (ACT) for psychogenic amnesia. Before treatment, Ben exhibited isolated retrograde and anterograde memory impairments. He received 12 therapy sessions that targeted experiential avoidance followed by two review sessions, six weeks and five months later. Ben's retrograde and anterograde memory impairments improved following therapy to return to within the "average" to "superior" ranges, which were maintained at follow-up. Further experimental single case study designs and larger group studies are required to advance the understanding of the effectiveness and efficacy of psychological therapy for psychogenic amnesia.

    We have treated three patients with conventional radiotherapy and one with stereotactic radiosurgery and report the follow-up results. A 63-year-old woman had a dural arteriovenous malformation (AVM) in the right cavernous sinus. She was irradiated using 10 MV X-ray with a total of 30 Gy. Post irradiation angiography showed a complete absence of dural AVM. A 62-year-old woman had a dural AVM fed by the left external carotid artery in the right cavernous sinus. Embolization by gelfoam was performed before irradiation. The irradiation was given with a total dose of 30 Gy. Post irradiation angiography showed disappearance of the dural AVM. A 26-year-old woman had a small AVM (about 20 x 15 x 15 mm) in the posterior corpus callosum. An operation was performed but the AVM was not excised completely. We irradiated to the residual AVM with a total of 30 Gy. The follow-up angiography one year after treatment, showed disappearance of the AVM. She had no neurological deficit two years after the treatment. A 14-year-old boy had a small AVM (about 20 x 15 x 10 mm) in the left anterior wall of the fourth ventricle. The AVM was located deeply, so an operation was not performed. Radiosurgery was undertaken four months after onset in Buenos Aires. The total dose was 36 Gy. The follow-up angiography one year after treatment, showed disappearance of the AVM. He also had no neurological deficit two years after the treatment. These four cases of AVM (two dural AVMs) were successfully treated by radiation therapy. No side effect was observed. (author)

    Anticoagulation therapy with warfarin requires periodic monitoring of prothrombin time-international normalized ratio (PT-INR) and adequate dose adjustments based on the data to minimize the risk of bleeding and thromboembolic events. In our hospital, we have developed protocol-based pharmaceutical care, which we called protocol-based pharmacotherapy management (PBPM), for warfarin therapy. The protocol requires pharmacists to manage timing of blood sampling for measuring PT-INR and warfarin dosage determination based on an algorithm. This study evaluated the efficacy of PBPM in warfarin therapy by comparing to conventional pharmaceutical care. From October 2013 to June 2015, a total of 134 hospitalized patients who underwent cardiovascular surgeries received post-operative warfarin therapy. The early series of patients received warfarin therapy as the conventional care (control group, n=77), whereas the latter received warfarin therapy based on the PBPM (PBPM group, n=68). These patients formed the cohort of the present study and were retrospectively analysed. The indications for warfarin included aortic valve replacement (n=56), mitral valve replacement (n=4), mitral valve plasty (n=22) and atrial fibrillation (n=29). There were no differences in patients' characteristics between both groups. The percentage time in therapeutic range in the first 10 days was significantly higher in the PBPM group (47.1%) than that in the control group (34.4%, PWarfarin therapy based on our novel PBPM was clinically safe and resulted in significantly better anticoagulation control compared to conventional care. © 2017 John Wiley & Sons Ltd.

    Direct oral anticoagulants (DOACs) are the treatment of choice for most patients with atrial fibrillation and/or noncancer-associated venous thromboembolic disease. Although routine monitoring of these agents is not required, assessment of anticoagulant effect may be desirable in special situations. The objective of this review was to summarize systematically evidence regarding laboratory assessment of the anticoagulant effects of dabigatran, rivaroxaban, apixaban, and edoxaban. PubMed, Embase, and Web of Science were searched for studies reporting relationships between drug levels and coagulation assay results. We identified 109 eligible studies: 35 for dabigatran, 50 for rivaroxaban, 11 for apixaban, and 13 for edoxaban. The performance of standard anticoagulation tests varied across DOACs and reagents; most assays, showed insufficient correlation to provide a reliable assessment of DOAC effects. Dilute thrombin time (TT) assays demonstrated linear correlation (r 2  = 0.67-0.99) across a range of expected concentrations of dabigatran, as did ecarin-based assays. Calibrated anti-Xa assays demonstrated linear correlation (r 2  = 0.78-1.00) across a wide range of concentrations for rivaroxaban, apixaban, and edoxaban. An ideal test, offering both accuracy and precision for measurement of any DOAC is not widely available. We recommend a dilute TT or ecarin-based assay for assessment of the anticoagulant effect of dabigatran and anti-Xa assays with drug-specific calibrators for direct Xa inhibitors. In the absence of these tests, TT or APTT is recommended over PT/INR for assessment of dabigatran, and PT/INR is recommended over APTT for detection of factor Xa inhibitors. Time since last dose, the presence or absence of drug interactions, and renal and hepatic function should impact clinical estimates of anticoagulant effect in a patient for whom laboratory test results are not available.

    To study the prevalence of poorly controlled vitamin K antagonist anticoagulation in Spain in patients with nonvalvular atrial fibrillation, and to identify associated factors. We studied 1056 consecutive patients seen at 120 cardiology clinics in Spain between November 2013 and March 2014. We analyzed the international normalized ratio from the 6 months prior to the patient's visit, calculating the prevalence of poorly controlled anticoagulation, defined as < 65% time in therapeutic range using the Rosendaal method. Mean age was 73.6 years (standard deviation, 9.8 years); women accounted for 42% of patients. The prevalence of poorly controlled anticoagulation was 47.3%. Mean time in therapeutic range was 63.8% (25.9%). The following factors were independently associated with poorly controlled anticoagulation: kidney disease (odds ratio = 1.53; 95% confidence interval, 1.08-2.18; P = .018), routine nonsteroidal anti-inflammatory drugs (odds ratio = 1.79; 95% confidence interval, 1.20-2.79; P = .004), antiplatelet therapy (odds ratio = 2.16; 95% confidence interval, 1.49-3.12; P < .0001) and absence of angiotensin receptor blockers (odds ratio = 1.39; 95% confidence interval, 1.08-1.79; P = .011). There is a high prevalence of poorly controlled vitamin K antagonist anticoagulation in Spain. Factors associated with poor control are kidney disease, routine nonsteroidal anti-inflammatory drugs, antiplatelet use, and absence of angiotensin receptor blockers.

    Full Text Available PURPOSE: A considerable percentage of patients with benign prostatic hyperplasia (BPH also have additional cardiac pathologies, which often require anticoagulant therapy. The aim of this study was to evaluate the efficacy and safety of photoselective vaporization of the prostate (PVP for BPH in cardiac patients receiving anticoagulant therapy. MATERIALS AND METHODS: A total of 67 patients suffering from BPH and high risk cardiac pathologies were operated on using laser prostatectomy. All patients had cardiac pathologies with bleeding disorders requiring anticoagulant use, and underwent standard urologic evaluation for BPH. Patients were treated with laser prostatectomy for relief of the obstruction using the KTP/532 laser energy at 80 W. RESULTS: The mean patient age was 71.4 years (range 55-80. Mean prostate volume on transrectal ultrasonography was 73.2 mL (range 44-120. Operation time ranged from 40 to 90 min, with an average value of 55 min. The average hospital stay was 48 hours (range 12-72 and the Foley catheters were removed within 48 hours, with a mean catheterization time of 34.2 ± 5.9 hours (0-48. No patient required an additional procedure due to severe bleeding necessitating intervention during the early postoperative phase. Mean International symptoms scoring system (IPSS values and post voiding residual volume decreased and peak urinary flow rate increased (p < 0.001. Our results showed that the mean prostate volume had decreased by 53% at 6 months. CONCLUSIONS: High-power photo selective laser vaporization prostatectomy is a feasible, safe, and effective alternative for the minimal invasive management of BPH, particularly in cardiac patients receiving anticoagulant therapy.

    Full Text Available The capabilities of antithrombotic therapy to prevent systemic thromboembolic events in nonvalvular atrial fibrillation (AF are substantially extended after clinically introducing novel oral anticoagulants (NOACs, such as dabigatran, rivaroxaban, and apixaban. World clinical experience with NOACs in AF has confirmed their efficacy and safety in both primary and secondary stroke prevention. At the same time, apixaban additionally reduces the risk of fatal outcomes and it is the safest among the NOACs against hemorrhagic events. The low risks of intracranial hemorrhage typical of NOACs should be taken into account when choosing oral anticoagulant therapy after hemorrhagic stroke in patients athigh risk for thromboembolic events due to AF. Whether NOACs may be used in acute myocardial infarction and during coronary stenting in the presence of nonvalvular AF, left ventricular thromboses, and cardiomyopathies is considered. In real clinical practice, nonvalvular AF may be accompanied by different cardiovascular diseases, by creating the situations where there are no specific guidelines for the use of NOACs. The results of comparing the clinical efficiency of different antithrombotic therapy regimens, the subanalysis of randomized trials, and experts’ opinions may assist a physician to substantiate their decisions. Thus, just a few NOACs that are similar and/or superior to warfarin in efficacy and safety have emerged to date. There are grounds to believe that many physicians will prefer direct anticoagulants to warfarin not only because of their proven efficacy, but also the rapid onset of their anticoagulant effect, neither interaction with a number of foods or drugs, and above all, nor need for regular laboratory blood testing. World post-marketingsurveillance and new clinical tests will be helpful in better estimating the benefits and risks of treatment with NOACs and in expanding indications for their use, which will considerably

    Full Text Available Tiffany Lee, Erin Davis, Jason Kielly School of Pharmacy, Memorial University, St John's, NL, Canada Background: Anticoagulant therapies provide management options for potentially life-threatening thromboembolic conditions. They also carry significant safety risks, requiring careful consideration of medication dose, close monitoring, and follow-up. Inpatients are particularly at risk, considering the widespread use of anticoagulants in hospitals. This has prompted the introduction of safety goals for anticoagulants in Canada and the USA, which recommend increased pharmacist involvement to reduce patient harm. The goal of this review is to evaluate the efficacy and safety of pharmacist-led inpatient anticoagulation services compared to usual or physician-managed care. Methods: This narrative review includes articles identified through a literature search of PubMed, Embase, and International Pharmaceutical Abstracts databases, as well as hand searches of the references of relevant articles. Full publications of pharmacist-managed inpatient anticoagulation services were eligible if they were published in English and assessed clinical outcomes. Results: Twenty-six studies were included and further divided into two categories: 1 autonomous pharmacist-managed anticoagulation programs (PMAPs and 2 pharmacist recommendation. Pharmacist management of heparin and warfarin appears to result in improvements in some surrogate outcomes (international normalized ratio [INR] stability and time in INR goal range, while results for others are mixed (time to therapeutic INR, length of stay, and activated partial thromboplastin time [aPTT] measures. There is also some indication that PMAPs may be associated with reduced patient mortality. When direct thrombin inhibitors are managed by pharmacists, there seems to be a shorter time to therapeutic aPTT and a greater percentage of time in the therapeutic range, as well as a decrease in the frequency of medication

There is a general tendency among physicians to underuse anticoagulants in the elderly, probably both because of underestimation of thromboembolic risk and overestimation of bleeding risk. The main indications for anticoagulation are venous thromboembolism (VTE prophylaxis in medical and surgical settings, VTE treatment, atrial fibrillation (AF and valvular heart disease. Available anticoagulants for VTE prophylaxis and initial treatment of VTE are low molecular weight heparins (LMWH, unfractionated heparin (UFH or synthetic anti-factor Xa pentasaccharide fondaparinux. For long-term anticoagulation vitamin K antagonists (VKA are the first choice and only available oral anticoagulants nowadays. Assessing the benefit-risk ratio of anticoagulation is one of the most challenging issues in the individual elderly patient, patients at highest hemorrhagic risk often being those who would have the greatest benefit from anticoagulants. Some specific considerations are of utmost importance when using anticoagulants in the elderly to maximize safety of these treatments, including decreased renal function, co-morbidities and risk of falls, altered pharmacodynamics of anticoagulants especially VKAs, association with antiplatelet agents, patient education. Newer anticoagulants that are currently under study could simplify the management and increase the safety of anticoagulation in the future.Keywords: anticoagulation, elderly patients, venous thromboembolism, hemorrhagic risk, atrial fibrillation, thrombin inhibitors, factor Xa

    This cross-sectional survey explored the characteristics and outcomes of direct oral anticoagulant (DOAC)-associated nontraumatic intracerebral hemorrhages (ICHs) by analyzing a large nationwide Japanese discharge database. We analyzed data from 2,245 patients who experienced ICHs while taking anticoagulants (DOAC: 227; warfarin: 2,018) and were urgently hospitalized at 621 institutions in Japan between April 2010 and March 2015. We compared the DOAC- and warfarin-treated patients based on their backgrounds, ICH severities, antiplatelet therapies at admission, hematoma removal surgeries, reversal agents, mortality rates, and modified Rankin Scale scores at discharge. DOAC-associated ICHs were less likely to cause moderately or severely impaired consciousness (DOAC-associated ICHs: 31.3%; warfarin-associated ICHs: 39.4%; p = 0.002) or require surgical removal (DOAC-associated ICHs: 5.3%; warfarin-associated ICHs: 9.9%; p = 0.024) in the univariate analysis. Propensity score analysis revealed that patients with DOAC-associated ICHs also exhibited lower mortality rates within 1 day (odds ratio [OR] 4.96, p = 0.005), within 7 days (OR 2.29, p = 0.037), and during hospitalization (OR 1.96, p = 0.039). This nationwide study revealed that DOAC-treated patients had less severe ICHs and lower mortality rates than did warfarin-treated patients, probably due to milder hemorrhages at admission and lower hematoma expansion frequencies.

    The risk of recurrent venous thromboembolism (VTE) approaches 40 per cent of all patients after 10 yr of follow up. This risk is higher in patients with permanent risk factors of thrombosis such as active cancer, prolonged immobilization from medical diseases, and antiphospholipid syndrome; in carriers of several thrombophilic abnormalities, including deficiencies of natural anticoagulants; and in patients with unprovoked presentation. Patients with permanent risk factors of thrombosis should receive indefinite anticoagulation, consisting of subtherapeutic doses of low molecular weight heparin in cancer patients, and oral anticoagulants in all other conditions. Patients whose VTE is triggered by major surgery or trauma should be offered three months of anticoagulation. Patients with unprovoked VTE, including carriers of thrombophilia, and those whose thrombotic event is associated with minor risk factors (such as hormonal treatment, minor injuries, long travel) should receive at least three months of anticoagulation. The decision as to go on or discontinue anticoagulation after this period should be individually tailored and balanced against the haemorrhagic risk. Post-baseline variables, such as the D-dimer determination and the ultrasound assessment of residual thrombosis can help identify those patients in whom anticoagulation can be safely discontinued. As a few emerging anti-Xa and anti-IIa compounds seem to induce fewer haemorrhagic complications than conventional anticoagulation, while preserving at least the same effectiveness, these have the potential to open new scenarios for decisions regarding the duration of anticoagulation in patients with VTE.

  16. Implementation of non-vitamin K antagonist oral anticoagulants in daily practice: the need for comprehensive education for professionals and patients.

    Non-vitamin K antagonist oral anticoagulants (NOACs) are increasingly used for the prevention and treatment of venous thromboembolism and for stroke prevention in patients with atrial fibrillation. NOACs do not require routine coagulation monitoring, creating a challenge to established systems for patient follow-up based on regular blood tests. Healthcare professionals (HCPs) are required to cope with a mixture of patients receiving either a vitamin K antagonist or a NOAC for the same indications, and both professionals and patients require education about the newer drugs. A European working group convened to consider the challenges facing HCPs and healthcare systems in different countries and the educational gaps that hinder optimal patient management. Group members emphasised the need for regular follow-up and noted national, regional and local variations in set-up and resources for follow-up. Practical incorporation of NOACs into healthcare systems must adapt to these differences, and practical follow-up that works in some systems may not be able to be implemented in others. The initial prescriber of a NOAC should preferably be a true anticoagulation specialist, who can provide initial patient education and coordinate the follow-up. The long-term follow-up care of patients can be managed through specialist coagulation nurses, in a dedicated anticoagulation clinic or by general practitioners trained in NOAC use. The initial prescriber should be involved in educating those who perform the follow-up. Specialist nurses require access to tools, potentially including specific software, to guide systematic patient assessment and workflow. Problem cases should be referred for specialist advice, whereas in cases for which minimal specialist attention is required, the general practitioner could take responsibility for patient follow-up. Hospital departments and anticoagulation clinics should proactively engage with all downstream HCPs (including pharmacists) to ensure

    Deaf patients with psychological problems have developmental handicaps and clinical characteristics that reduce the effectiveness of traditional modes of psychotherapy. Attempts have been made to utilize individual and group therapy, but family therapy has been largely overlooked as a method of alleviating problems of the deaf. Clinical and research writings provide us with rich insights into the family dynamics of the deaf. These data suggest to the authors that the problems of deaf individuals are largely related to family problems, and therefore merit a family orientation as the focus for treatment. This paper describes an attempt to apply family therapy with a range of deaf patients over a period of two years. From a review of their work, the authors conclude that family therapy can be effective, particularly in the treatment of deaf adolescents and children.

    Full Text Available Smoking is one of the most common addictions with devastating biopsychosocial consequences. Both medical treatment and pschotherapy are utilized in smoking cessation. Acceptance and commitment therapy holds the notion that smoking cessation rates are determined not so much by the negative affect and withdrawal symptoms per se, but by the avoidant and inflexible responding style. Acceptance and commitment therapy, through targeting the avoidance of internal stimuli and concomitant inflexible responding pattern, has yielded successful results.This article presents application of acceptance and commitment therapy step by step to a chronic smoker who quitted smoking at the end of therapy sessions.

    Inhalation of pressurized 100% oxygen is a helpful adjunctive treatment for certain patients, because the increased oxygen carried by the blood to the tissue enhances new growth of microcirculation and, thus, healing. Patients with tissue breakdown after radiation therapy, refractory osteomyelitis, gas gangrene, soft-tissue infection with necrosis from mixed aerobic and anaerobic organisms, crush injuries resulting in acute ischemia, and compromised skin grafts or non-healing wounds are likely to benefit from hyperbaric oxygen therapy

    Full Text Available Patrick P Kneeland, Margaret C FangThe University of California, San Francisco Division of Hospital Medicine, San Francisco, CA, USAAbstract: Warfarin therapy reduces morbidity and mortality related to thromboembolism. Yet adherence to long-term warfarin therapy remains challenging due to the risks of anticoagulantassociated complications and the burden of monitoring. The aim of this paper is to review determinants of adherence and persistence on long-term anticoagulant therapy for atrial fibrillation and venous thromboembolism. We evaluate what the current literature reveals about the impact of warfarin on quality of life, examine warfarin trial data for patterns of adherence, and summarize known risk factors for warfarin discontinuation. Studies suggest only modest adverse effects of warfarin on quality of life, but highlight the variability of individual lifestyle experiences of patients on warfarin. Interestingly, clinical trials comparing anticoagulant adherence to alternatives (such as aspirin show that discontinuation rates on warfarin are not consistently higher than in control arms. Observational studies link a number of risk factors to warfarin non-adherence including younger age, male sex, lower stroke risk, poor cognitive function, poverty, and higher educational attainment. In addition to differentiating the relative impact of warfarin-associated complications (such as bleeding versus the lifestyle burdens of warfarin monitoring on adherence, future investigation should focus on optimizing patient education and enhancing models of physician–patient shared-decision making around anticoagulation.Keywords: anticoagulation, warfarin, adherence, persistence, thromboembolism

    Two cases of primary Ewing's sarcoma of the rib are reported, in which radiation therapy was quite effective. Case 1 was an 18-year-old female who had had an operation and radiation therapy for Ewing's sarcoma of the left 7th rib. She was referred to our hospital after a recurrent tumor was found. Radiation therapy (tumor dose 46.2 Gy) and chemotherapy were given. The tumor disappeared and there has been no relapse for 1 year and 3 months after the treatment. Case 2 was a 2-year-old-infant. Radiation therapy (tumor dose 74 Gy) was given for primary Ewing's sarcoma of the left 6th rib. The tumor became small and was successfully removed at operation. There has been no relapse or distant metastasis for 8 months following the operation. We emphasize the importance of multidisciplinary treatment in case 1 and the usefulness of preoperative radiotherapy in case 2. (author)

    The profession would benefit from greater and routine generation of causal evidence pertaining to the impact of music therapy interventions on client outcomes. One way to meet this goal is to revisit the use of Single Case Designs (SCDs) in clinical practice and research endeavors in music therapy. Given the appropriate setting and goals, this design can be accomplished with small sample sizes and it is often appropriate for studying music therapy interventions. In this article, we promote and discuss implementation of SCD studies in music therapy settings, review the meaning of internal study validity and by extension the notion of causality, and describe two of the most commonly used SCDs to demonstrate how they can help generate causal evidence to inform the field. In closing, we describe the need for replication and future meta-analysis of SCD studies completed in music therapy settings. SCD studies are both feasible and appropriate for use in music therapy clinical practice settings, particularly for testing effectiveness of interventions for individuals or small groups. © the American Music Therapy Association 2014.

    This paper describes the diagnostic and treatment utility of visual art therapy in a case of sporadic Creutzfeldt-Jakob disease. Visual art therapy was compared longitudinally with clinical and neuroimaging data over five-month period in an autopsy-confirmed case of sporadic Creutzfeldt-Jakob disease of MM2-cortical subtype. Art therapy sessions and content were useful in ascertaining neuropsychiatric symptoms during the course of her illness. Art therapy offered a unique emotional and cognitive outlet as illness progressed. Patients and families affected by sporadic Creutzfeldt-Jakob disease may benefit from art therapy despite the rapidly progressive nature of the illness. Art therapy can also be useful for assessment of patients with sporadic Creutzfeldt-Jakob disease by healthcare professionals.

    We report a case of rhabdomyosarcoma of the trachea in a 14-month-old child, and we present the first reported use of proton beam therapy for this tumour. A 14-month-old girl presented acutely with a seven-day history of biphasic stridor. Emergency endoscopic debulking of a posterior tracheal mass was undertaken. Histological examination revealed an embryonal rhabdomyosarcoma with anaplasia. Multimodality therapy with surgery and chemotherapy was administered in the UK, and proton beam therapy in the USA. Only three cases of rhabdomyosarcoma of the trachea have previously been reported in the world literature. This is the first reported case of treatment of this tumour with proton beam therapy. Compared with conventional radiotherapy, proton beam therapy may confer improved long-term outcome in children, with benefits including reduced irradiation of the spinal cord.

    Anticoagulant therapy has been used with great effect for decades for the prevention of stroke among patients with atrial fibrillation. In recent years, the therapeutic armamentarium has been strengthened considerably, with the addition of anticoagulants acting through novel pathways. The currently available novel agents are apixaban, rivaroxaban and dabigatran. These novel oral anticoagulants (NOACs) were approved for use on the basis of major clinical trials clearly demonstrating improved risk reductions compared to warfarin for stroke and/or major bleeding events. In these studies, apixaban and dabigatran 150 mg each significantly reduced the risk of stroke, while apixaban and dabigatran 110 mg reduced the risk of major bleeding compared to warfarin. Extrapolating the results of the randomized clinical trials on NOACs to all patients is not possible, as the strict design of clinical trials yields information that is directly applicable to a relatively narrow spectrum of patients. To control for confounding variables, randomized studies restrict enrolment to a prespecified set of criteria that do not necessarily reflect the profiles of all those who could potentially benefit from these agents. Research continues using the trial databases, in an attempt to better identify patient subgroups who do or do not benefit from each of the agents. At the European Society of Cardiology (ESC) annual meetings in London in 2015 and in Rome in 2016, there were several presentations and posters providing this type of evidence. Perhaps more important, as real-world experience with these agents grows, we are beginning to obtain meaningful new information about the NOACs in everyday use. This has involved the study of large databases including patients receiving these medications in clinical situations less stringently defined than in the randomized clinical trials. These include purpose-built registries, observational studies, and analyses of healthcare administrative databases

    There is a high prevalence of anxiety disorders including specific phobias and panic disorder in the United States and Europe. A variety of therapeutic modalities including pharmacotherapy, cognitive behavioral therapy, systematic desensitization, hypnosis, in vivo exposure, and virtual reality exposure therapy have been applied. No one modality has been entirely successful. There has been only a limited attempt to combine psychological therapies in the treatment of specific phobias and panic disorder and what has been done has been primarily with systematic desensitization or cognitive behavioral therapy along with hypnotherapy. I present two cases of multiple specific phobias that were successfully treated with hypnotherapy combined with virtual reality exposure therapy or in vivo exposure therapy. The rationale for this integrative therapy and the neurobiological constructs are considered.

    A case of radiation-induced sarcoma of the chest wall after radiation therapy for breast cancer is reported. A 69-year-old woman underwent mastectomy with axillary lymph node dissection followed by linac therapy of 50 Gy delivered to the left axilla, left supraclavicular area, and parasternal area. During therapy for bone and liver metastases, a tumor was noted in the left chest wall 15 years after radiation therapy. Incisional biopsy was performed. Histological diagnosis was spindle cell sarcoma. Radiation-induced sarcoma was suspected because the tumor developed 15 years after radiation therapy within the same area. Radiation-induced sarcoma is a rare tumor, but radiation therapy following breast-conserving therapy is widely employed. It is important to be aware of the possibility of radiation-induced sarcoma.

    Background: The use of non-vitamin K antagonist oral anticoagulants (NOACs) for stroke prophylaxis in atrial fibrillation (AF) is increasing rapidly. We compared characteristics of AF patients initiated on NOACs versus vitamin K antagonists (VKAs). Methods: Using Danish nationwide registry data, we...... compared with a VKA [odds ratio (OR) 1.35, 95% confidence interval (CI) 1.28–1.43]. By contrast, patients with a history of myocardial infarction were less likely to be initiated on a NOAC compared with a VKA (OR 0.72, 95% CI 0.67–0.77). Conclusions: Atrial fibrillation patients who were initiated...

    A 56-year-old woman with recurrent gastric cancer treated with PMU therapy, combined CDDP 75 mg/m2 i.v. MMC 10 mg/body i.v. and UFT 400mg/body/2 alpha/day p.o., was reported. She was admitted because of cervical lymph node swelling and abdominal tumor (para-aorta lymph node swelling). She was treated two times with this therapy and induced into complete remission. The serum CEA level, more than 500 ng/ml before the treatment, was reduced to 6.7 ng/ml after treatment. She has currently been free of disease for more than four weeks. We conclude that this PMU therapy is extremely effective for indurable gastric cancer.

    range. Only one study (70 participants) reported the mean time in therapeutic range as a percentage. This study found that in the group of participants deemed to have poor INR control, the addition of 150 micrograms (mcg) oral vitamin K significantly improved anticoagulation control in those with unexplained instability of response to warfarin. The second study (30 participants) reported the effect of 175 mcg oral vitamin K versus placebo on participants with high variability in their INR levels. The study concluded that vitamin K supplementation did not significantly improve the stability of anticoagulation for participants on chronic anticoagulation therapy. However, the study was only available in abstract form, and communication with the lead author confirmed that there were no further publications. Therefore, we interpreted this conclusion with caution. Neither study reported any thromboembolic events, haemorrhage, or death from the addition of vitamin K supplementation. Two included studies in this review compared whether the addition of a low dose (150 to 175 mcg) of vitamin K given to participants with a high-variability response to warfarin improved their INR control. One study demonstrated a significant improvement, while another smaller study (published in abstract only) suggested no overall benefit. Currently, there are insufficient data to suggest an overall benefit. Larger, higher quality trials are needed to examine if low-dose vitamin K improves INR control in those starting or already taking warfarin.

    Recent outcomes for Cognitive Processing Therapy (CPT) and Prolonged Exposure (PE) therapy indicate that as many as 60-72% of patients retain their PTSD diagnosis after treatment with CPT or PE. One emerging therapy with the potential to augment existing trauma focused therapies is Accelerated Resolution Therapy (ART). ART is currently being used along with evidence based approaches at Fort Belvoir Community Hospital and by report has been both positive for clients as well as less taxing on professionals trained in ART. The following is an in-practice theoretical comparison of CPT, EMDR and ART with case examples from Fort Belvoir Community Hospital. While all three approaches share common elements and interventions, ART distinguishes itself through emphasis on the rescripting of traumatic events and the brevity of the intervention. While these case reports are not part of a formal study, they suggest that ART has the potential to augment and enhance the current delivery methods of mental health care in military environments.

    Introduction Low-molecular-weight heparins are the standard treatment for cancer-associated thrombosis. Recently, direct oral anticoagulants are a new option for thrombosis treatment; however, data supporting the use of direct oral anticoagulants for cancer-associated thrombosis are limited. Objectives The primary objective of this study was to determine the rate of recurrent cancer-associated thrombosis and major bleeding within 6 months of starting either low-molecular-weight heparin or direct oral anticoagulant for treatment of cancer-associated thrombosis. Secondary objectives were to determine the rates of clinically relevant-non-major bleeding and all-cause mortality. Patients/methods This is a retrospective cohort study including adults with cancer-associated thrombosis treated with low-molecular-weight heparin or direct oral anticoagulant between 2010 and 2016 at the Ohio State University. Medical records were reviewed for 6 months after initiation of anticoagulation or until the occurrence of recurrent cancer-associated thrombosis, major bleeding, cessation of anticoagulation of interest, or death, whichever occurred first. Results Four hundred and eighty patients were included (290 low-molecular-weight heparin and 190 direct oral anticoagulant). Patients treated with direct oral anticoagulant were found to carry "lower risk" features including cancer with lower VTE risk and lower rate of metastatic disease. After adjustment for baseline differences, there was no significant difference in the rate of recurrent cancer-associated thrombosis (7.2% low-molecular-weight heparin vs 6.3% direct oral anticoagulant, p = 0.71) or major bleeding (7.6% low-molecular-weight heparin vs 2.6% direct oral anticoagulant, p = 0.08). Conclusions Our study demonstrates that in a select population of cancer patients with VTE, direct oral anticoagulant use can be as effective and safe compared to the standard therapy with low-molecular-weight heparin.

    We assessed the real-life use of direct oral anticoagulants (DOACs) in patients with venous thromboembolism (VTE) and exclusion criteria for randomized trials. From 2013 to 2016, 3,578 of 18,853 patients (19%) had exclusion criteria. Irrespective of which anticoagulant was chosen, they had more VTE recurrences (hazard ratio (HR): 3.10; 95% confidence interval (CI): 2.47-3.88), major bleeds (HR: 4.10; 95% CI: 3.38-4.96), and deaths (HR: 9.47; 95% CI: 8.46-10.6) than those without exclusion criteria. During initial therapy, no patient with exclusion criteria on DOACs (n = 115) recurred, but those on rivaroxaban bled less often (adjusted HR: 0.18; 95% CI: 0.04-0.79) than those on unfractionated heparin (n = 224) and similar to those (n = 3,172) on low-molecular-weight (LMWH) heparin. For long-term therapy, patients on rivaroxaban (n = 151) had nonsignificantly fewer VTE recurrences (adjusted HR: 0.74; 95% CI: 0.08-1.32) and major bleeds (adjusted HR: 0.41; 95% CI: 0.15-1.15) than those on LMWH (n = 2,071). The efficacy and safety of DOACs were similar to standard therapy. © 2017 American Society for Clinical Pharmacology and Therapeutics.

    The use of anticoagulants and older age are the main risk factors for chronic subdural hematoma (CSDH). Because the age of the population and use of anticoagulants are increasing, a growing number of CSDH cases is expected. To address this issue, we analyzed the impact of anticoagulants on postsurgical outcome in patients in the intensive care unit (ICU). Demographic data, coagulation parameters, surgical details, radiologic appearance of hematoma, Glasgow Coma Scale (GCS) score on admission, and Glasgow Outcome Scale (GOS) score on discharge were retrieved and retrospectively analyzed in 98 patients with CSDH treated in the neurosurgical ICU using correlation coefficient tests and multivariate analysis test. Overall outcome was good (GOS score 4 and 5) in 55.1% of patients. Overall mortality was 9.1%. There was a correlation between GCS score on admission and GOS score. There was no correlation between hematoma thickness/radiologic appearance and impaired coagulation. Disturbance in thrombocyte function (usually resulting from aspirin intake) correlated with improved outcome, whereas warfarin-related coagulopathy correlated with poor recovery. Nevertheless, patients with thrombocytopathy presented with better initial GCS scores. Neither hematoma size nor recurrence rate affected the outcome. The size of CSDH was not associated with poor outcome and is not necessarily determined by the use of anticoagulants. Coagulopathy does not rule out a good outcome, but the impact of anticoagulation on treatment results in CSDH varies between the main groups of drugs (warfarin vs. antiplatelet drugs). Patients in good neurologic condition on ICU admission have better chances of recovery. Copyright © 2016 Elsevier Inc. All rights reserved.

    2015-06-01

    Intracranial hemorrhage (ICH) is one of the most serious and lethal complications of anticoagulants with a reported incidence of 5-18.5 %. Computed tomographic (CT) findings, should be carefully studied because early diagnosis and treatment of oral anticoagulant use-associated hematomas are vitally important. In the present study, CT findings of intraparenchymal hematomas associated with anticoagulant and antihypertensive use are presented. This study included 45 patients (25 men, 20 women) under anticoagulant (21 patients) or antihypertensive (24 patients) treatment who had brain CT examinations due to complaints and findings suggesting cerebrovascular disease during July 2010-October 2013 period. CT examinations were performed to determine hematoma volumes and presence of swirl sign, hematocrit effect, mid-line shift effect, and intraventricular extension. The patients were 40-89 years of age. In four cases, a total of 51 intraparenchymal hematomas (42 cerebral, 7 cerebellar and 2 brain stem) were detected in multiple foci. Hematoma volumes varied from 0.09 to 284.00 ml. Swirl sign was observed in 87.5 and 63.0 % of OAC-associated ICHs and non-OAC-associated ICHs, respectively. In addition, hematocrit effect was observed in 41.6 % of OAC-associated and in 3.7 % of non-OAC-associated ICHs. Volume increases were observed in all 19 hematomas where swirl sign was detected, and follow-up CT scanning was conducted. Mortality of OAC-associated ICHs was correlated with initial volumes of hematoma, mid-line shift amount, and intraventricular extension. Detection of hematocrit effect by CT scanning of intracranial hematomas should be cautionary in oral anticoagulant use, while detection of swirl sign should be suggestive of active hemorrhage.

    2015-01-01

    Using a case study, this article presents narrative therapy as an effective psychotherapy practice for work with victims of motor vehicle accidents. By troubling the standard cognitive behavioral approaches as deficit focused, narrative therapy is outlined as an approach that is focused on the skills and values present in the client's life; it is an approach that allows the client to take authorship over his or her concerns and enact change. This article is meant to be an example of narrative therapy's usefulness and open space for conversation about rehabilitation therapies that focus less on structure and more on strength.

  13. Shared written case formulations and weight change in outpatient therapy for anorexia nervosa: a naturalistic single case series.

    Gladwin, Alice M; Evangeli, Michael

    2013-01-01

    The therapeutic effects of written shared case formulations are underexplored and have not been examined in anorexia nervosa. This study explored the relationship between (a) the delivery (b) the quality of a shared written case formulation and weight in outpatient psychological therapy for anorexia nervosa. A naturalistic single case series approach was used to examine the case notes of women who had attended a specialist eating disorders service over a 2-year period. The case notes of 15 adult women who had undergone outpatient psychological therapy for anorexia nervosa with a shared written case formulation component were reviewed. The impact of the quality of the case formulation on weekly weight was examined for 14 of the clients where the case formulation was available. The nature of the relationship between the delivery of the written shared case formulation and weight was examined for all 15 clients. There was some evidence to support an association between delivery of the shared written case formulation and weight changes (both weight gain [five out of 15 clients] and weight loss [three out of 15 clients]) in individual cases. Higher case formulation quality was related to cases where weight change did not occur. The delivery of case formulations can be associated with important therapeutic change (both beneficial and potentially harmful) in anorexia nervosa. Future research into the causal mechanisms associated with sharing formulations will face the challenge of adopting strategies that allow for an in-depth exploration of complex therapy variables whilst overcoming methodological challenges.

    Full Text Available Artemisinin-based combination therapy-resistant malaria is rare in Sub-Saharan Africa. The World Health Organization identifies monitoring and surveillance using day-3 parasitaemia post-treatment as the standard test for identifying suspected artemisinin resistance. We report three cases of early treatment failure due to possible artemisinin-based combination therapy-resistant Plasmodium falciparum malaria. All cases showed adequate clinical and parasitological responses to quinine. This study reveals a need to re-evaluate the quality and efficacy of artemisinin-based combination therapy agents in Nigeria and Sub-Saharan Africa.

    Nonvariceal upper gastrointestinal bleeding emerges as a major complication of using antiplatelet agents and/or anticoagulants and represents a clinical challenge in patients undergoing these therapies. To characterize patients with nonvariceal upper gastrointestinal bleeding related to antithrombotics and their management, and to determine clinical predictors of adverse outcomes. Retrospective cohort of adults who underwent upper gastrointestinal endoscopy after nonvariceal upper gastrointestinal bleeding from 2010 to 2012. The outcomes were compared between patients exposed and not exposed to antithrombotics. Five hundred and forty-eight patients with nonvariceal upper gastrointestinal bleeding (67% men; mean age 66.5 ± 16.4 years) were included, of which 43% received antithrombotics. Most patients had comorbidities. Peptic ulcer was the main diagnosis and endoscopic therapy was performed in 46% of cases. The 30-day mortality rate was 7.7% (n = 42), and 36% were bleeding-related. The recurrence rate was 9% and 14% of patients with initial endoscopic treatment needed endoscopic retreatment. There were no significant differences between the exposed and non-exposed groups in most outcomes. Co-morbidities, hemodynamic instability, high Rockall score, low hemoglobin (7.76 ± 2.72 g/dL) and higher international normalized ratio (1.63 ± 1.13) were associated significantly with mortality in a univariate analysis. Adverse outcomes were not associated with antithrombotic use. The management of nonvariceal upper gastrointestinal bleeding constitutes a challenge to clinical performance optimization and clinical cooperation.

    We report a case of rhabdomyolysis related to S-1 plus oxaliplatin(SOX)therapy for liver metastasis of gastric cancer. A 76- year-old man who had received SOX therapy for metastatic gastric cancer was admitted to our hospital for a chief complaint of fatigue and weakness. He diagnosed with rhabdomyolysis related to SOX therapy because of his symptoms and because his laboratory studies showed significant elevation of his serum creatine kinase(CK)level. The symptoms disappeared and the CK level normalized following large-volume transfusions. Rhabdomyolysis following SOX therapy is a very rare, but severe adverse event. This is the first detailed case report of rhabdomyolysis related to SOX therapy.

  18. Systemic relational therapy and the case from the clinical practice

    Directory of Open Access Journals (Sweden)

    2003-06-01

    Full Text Available In the present article are represented the principal guidelines of the systemic relational model of psychotherapy and an example of clinical practice where the pacient was incluced in this kind of therapy. In the essence of systemic relational model there is a person which is captured in the repetition of old patterns in spite of its painfulness and hardness. Captured and helpless in old patterns, the person not only repeats but also recreates them, because they promise safety, belonging and connectedness. From the review of the therapy it is evident that behind the pacient's concrete problems stands her family system to which she is loyal in the way that only deepens her distress. By the increasing the responsability for herself, for her feelings and her acts, it increases the pacient's funcionality, too.

    Since 1989, we have cured 367 persons of facial acne of different course by using direct irradiation of high-power CO2 laser combing with operative therapy of low-power CO2 laser. The cure rate is 100 percent. In this paper, we stated the therapeutic approach. It was shown that this therapeutic approach is simple and effective, and its recurrence rate is zero. There are no cicatrices after healing. It is easy to accept it, and is worthy of extension.

    To determine the current status of anticoagulation control in patients with nonvalvular atrial fibrillation treated with vitamin K antagonists in the primary care setting in Spain. The PAULA study was a multicenter cross-sectional/retrospective observational study conducted throughout Spain. The study included patients with nonvalvular atrial fibrillation who had been receiving vitamin K antagonist therapy during the past year and were attended at primary care centers. International normalized ratio (INR) values over the past 12 months were recorded. The degree of anticoagulation control was defined as the time the patient had remained within the therapeutic range and was determined by both the direct method (poor control < 60%) and by the Rosendaal method (poor control < 65%). The study assessed 1524 patients (mean age, 77.4 ± 8.7 years; 48.6% women; 64.2% in permanent atrial fibrillation; CHADS2 mean, 2.3 ± 1.2; CHA2DS2-VASc, 3.9 ± 1.5, and HAS-BLED, 1.6 ± 0.9). The mean number of INR readings recorded per patient was 14.4 ± 3.8. A total of 56.9% of patients had adequate INR control according to the direct method and 60.6% according to the Rosendaal method. The multivariate analysis identified the following predictors for poor INR control: female sex, dietary habits potentially affecting anticoagulation with vitamin K antagonists, multidrug therapy, and a history of labile INR. Approximately 40% of patients (43.1% by the direct method and 39.4% by the Rosendaal method) with nonvalvular atrial fibrillation who were receiving anticoagulation therapy with vitamin K antagonists in primary care in Spain had poor anticoagulation control during the previous 12 months.

  1. The role of interventional radiology in the management of deep venous thrombosis: advanced therapy.

    LENUS (Irish Health Repository)

    O'Sullivan, Gerard J

    2011-06-01

    Deep vein thrombosis (DVT) is often managed with a health care pathway that funnels patients to anticoagulation therapy alone. This "usual treatment" is designed to stop propagation and embolisation of venous thrombus but not remove it. Surgical thrombectomy was once the only option in severe cases in which limbs were threatened, but thrombus removal is no longer restricted to emergency cases. Interventional radiologists are now using advanced endovascular techniques to achieve thrombus removal in a minimally invasive manner in a very short treatment time, thereby quickly restoring patency, relieving acute symptoms, and potentially limiting the subsequent development of postthrombotic syndrome when followed with anticoagulation and compression regimens. This article provides an overview of the interventions available for treating DVT. One of the newer "single-session" techniques is isolated pharmacomechanical thrombolysis, which is described here in detail with supporting cases.

    2014-10-01

    Full Text Available Venous thromboembolism (VTE, encompassing deep vein thrombosis and pulmonary embolism, requires an immediate anticoagulation, that has been carried out so far by administering a parenteral anticoagulant drug (heparin or derivatives overlapped with an oral vitamin K antagonist (VKA, more often warfarin. Several new direct oral anticoagulants (DOACs, with a mechanism of action completely different than VKA, have been developed in recent years. Recent clinical trials have investigated their use in VTE patients showing results at least equal for efficacy and safety, and sometime even better, as the standard anticoagulant treatment. There are differences in the design of the trials. In two cases the involved DOAC was administered immediately after VTE diagnosis as a single drug treatment (rivaroxaban and apixaban, whereas in the other trials (involving dabigatran and edoxaban the DOAC was administered after an initial course of approximately 7 days with heparin or derivatives. Some clinical trials have also investigated the use of DOACs for extended anticoagulant treatment after the acute phase. Aim of this article is to review the results of the currently available clinical trials that have compared the use of DOACs versus the standard of care in patients with VTE.

    Vocal fold hemorrhage can represent a disastrous and potentially career ending injury to a singer or professional voice user. The risk factors of vocal fold hemorrhage, including laryngeal trauma, phonotrauma, aspirin and nonsteroidal antiinflammatories, and hormonal imbalances are well known. We present a case of an opera singer who developed recurrent vocal fold hemorrhage associated with coumadin anticoagulation therapy. This case highlights the importance of the risk of vocal fold hemorrhage to professional singers and professional voice users and offers an alternative to long-term coumadin therapy in this select population.

    Full Text Available This paper addresses the impact of language on cognitive behavioural therapy. Language is emotive and studies carried out in the linguistic field have shown second language is less emotive when describing events occuring in the first language. This paper has been written based on the experiences of a cognitive behavior therapy (CBT service providing therapy to patients from a diverse cultural and ethnic population. Patients whose first language is not English often receive therapy in their second language. Global migration is a common phenomenon and mainly occurs for economic reasons or threat of violence. This paper has been drawn from the results of a literature review on first and second languages and therapy. Despite being an area that is extremely relevant to therapy, there is an apparent lack of literature in relation to cognitive behavioural therapy for depression and other disorders. CBT is one of the recommended therapies by National Institute of Health and Clinical Excellence (NICE for the treatment of depression and anxiety disorders. Findings from the linguistic field highlight the potential short comings providing therapy in a patient’s second language. The aim of this paper is to highlight the importance that therapists working in this field have an understanding of how first and second languages function and the role they play in maintaining patients’ psychological problems. This practice paper discusses measures that can be used in cognitive behavioural therapy to deal with this using a case example.

    2015-10-01

    Antiphospholipid syndrome (APS), an acquired thrombotic condition, is a complex clinical state characterized by the presence of circulating antiphospholipid antibodies in patients with thrombosis or pregnancy morbidity. Revised APS classification criteria are used for diagnosis, which include at least one clinical criterion (thrombosis or pregnancy loss) and at least one of the laboratory criteria [anticardiolipin antibodies, anti-β2GPI antibodies, lupus anticoagulant (LA)]. LA is also an independent risk factor for developing thrombosis, though some LA-positive cases have been reported to have a bleeding symptom. Lupus anticoagulant-hypoprothrombinemia syndrome (LAHPS) is a rare disorder characterized by a bleeding tendency due to low prothrombin activity in patients with LA, and has recently been reported not only in children but also in adults We have encountered LA cases with bleeding and low coagulation factor activities except for prothrombin. Based on our findings, we propose that LA-positive cases with a bleeding symptom and characterized by low coagulation factor activity including prothrombin be termed lupus anticoagulant-associated coagulopathy (LAAC). Furthermore, coagulation factor autoantibodies are often detected in LAAC patients; thus, correct measurement of LA is important to distinguish LAAC patients from those possessing an inhibitor to coagulation factors such as acquired hemophilia A as well as to select the optimal therapeutic strategy.

    We report two cases of airway obstruction due to several radiotherapies. In the first case, although a “cannot ventilate, cannot intubate” (CVCI) situation arose, we performed cricothyrotomy, thus saving the patient. In the second case, we were able to perform bronchoscopy early to assess her laryngeal edema before nasal intubation and tracheotomy were performed. As a result, a potentially distressing situation for the patient was prevented. We must be careful of airway obstructions that can occur in patients after several radiotherapies. (author)

    Since non-vitamin K antagonist oral anticoagulants (NOACs) were released for clinical use, many studies have investigated its effectiveness in stroke prevention. In this study, to determine whether or not there is a difference in outcome in secondary stroke prevention between warfarin and NOACs, patients with embolic stroke with newly prescribed anticoagulants were prospectively analyzed. Patients with acute ischemic stroke, who newly started anticoagulant therapy, were consecutively asked to participate in this study. Enrolled patients (76.3 ± 11.0 years old) were classified into warfarin (n = 48), dabigatran (n = 73), rivaroxaban (n = 49), and apixaban (n = 65). The outcome in 1 year was prospectively investigated at outpatient clinic or telephone interview. Recurrence of stroke and death was considered as the critical incidence. The prevalence of risk factors was not different among all medicines. Patients with dabigatran showed significantly younger onset age (P incident rates were 7.1%, 15.3%, 19.0%, and 29.7% for dabigatran, apixaban, rivaroxaban, and warfarin, respectively. Dabigatran showed relatively better outcome compared with warfarin (P = .069) and rivaroxaban (P = .055). All patients on NOACs presented lower cumulative stroke recurrence compared with warfarin. Even in the situation of secondary stroke prevention, noninferiority of NOACs to warfarin might be demonstrated. Copyright © 2018 National Stroke Association. Published by Elsevier Inc.

    Full Text Available AIM: To investigate a comprehensive treatment for accommodative esotropia.METHODS: Eighty patients with accommodative esotropia were analyzed. All cases wore corrective glasses 7d after mydriasis by 10g/L atropine. The pupils were all comprehensively trained. If the position of the esotropic eyes could not be corrected by spectacles and both eyes had similar visual acuity in one year, surgical intervention was taken to correct the position. Refraction, visual acuity, visual function and strabismus degree change before and after treatment were evaluated.RESULTS: One year after wearing glasses, 50 cases had corrected eye position through correction and 30 cases were partially accommodative esotropia. Ten cases of esotropia degree >+15△ which could not be complete corrected by cure correction got surgical intervention. Seven cases of them got normal eye positions and 3 cases were over corrected 10△-20△. After comprehensive treatment of 3 years, the cure rate of amblyopia was 88.7%.CONCLUSION: The treatment for accommodative esotropia is a comprehensive course. It is necessary to pay attention to eye position correction, but also for the treatment of amblyopia, while paying attention to establish binocular vision.

Recently, there has been an increase in the use of music therapy and other creative arts therapies in the care of combat injured service members returning to the United States from Iraq and Afghanistan, especially those with complex blast-related injuries. This case report describes the role of music therapy in the interdisciplinary rehabilitation of a severely injured service member. Music therapy was provided as stand-alone treatment and in co-treatment with speech language pathology, physical therapy, and occupational therapy. The report is based on clinical notes, self-reports by the patient and his wife, and interviews with rehabilitation team members. In collaboration with other treatment disciplines, music therapy contributed to improvements in range of motion, functional use of bilateral upper extremities, strength endurance, breath support, articulation, task-attention, compensatory strategies, social integration, quality of life, and overall motivation in the recovery process. The inclusion of music therapy in rehabilitation was highly valued by the patient, his family, and the treatment team. Music therapy has optimized the rehabilitation of a service member through assisting the recovery process on a continuum from clinic to community. Implications for Rehabilitation Music therapy in stand-alone sessions and in co-treatment with traditional disciplines can enhance treatment outcomes in functional domains of motor, speech, cognition, social integration, and quality of life for military populations. Music therapists can help ease discomfort and difficulty associated with rehabilitation activities, thereby enhancing patient motivation and participation in interdisciplinary care. Music therapy assists treatment processes from clinic to community, making it highly valued by the patient, family, and interdisciplinary team members in military

    The incidence of acute upper gastrointestinal bleeding is about 85-108/100,000 inhabitants per year, nonvariceal bleeding accounts for 80-90%. Antiplatelet and anticoagulation treatment are the significant risk factors for upper gastrointestinal bleeding. To evaluate the occurrence of upper gastrointestinal bleeding in the general community of patients in a county hospital. And to compare the role played by antiplatelet and anticoagulation drugs and other risk medication. Retrospective analysis of patients over 18 years of age who underwent endoscopy for acute upper gastrointestinal bleeding or anaemia (haemoglobinupper gastrointestinal tract during a hospital stay in 2013 (from January to June). We included 111 patients of average age 69±15 years, men 60%. Nonvariceal bleeding accounted for 90% of the cases. None of the patients with variceal bleeding (10% of patients) took antiplatelet or anticoagulation therapy. There were 100 patients with nonvariceal bleeding of average age 70±15, 61% men. With the symptoms of acute bleeding (hematemesis, melena) presented in 73% of patients. The most frequent cause of bleeding was gastric and duodenal ulcer (54%). 32% of patients with nonvariceal bleeding had antiplatelets, 19% anticoagulants and 10% used nonsteroidal anti-inflammatory drugs, selective serotonin reuptake inhibitors or corticosteroids. 30-days mortality of patients with nonvariceal bleeding was 11%, annual mortality was 23%. There was no significant difference in mortality, blood transfusion requirements or surgical intervention between the patients with antithrombotic agents and without them. 25% of patients (8 patients) using acetylsalicylic acid did not fulfil the indication for this treatment. Among the patients examined by endoscopy for symptomatic nonvariceal bleeding and/or anaemia (haemoglobingastrointestinal bleeding. With regard to that, it is alarming, that there still exists a nonnegligible percentage of patients taking acetylsalicylic acid even

    The use of bee venom as a therapeutic agent for the relief of joint pains dates back to Hippocrates, and references to the treatment can be found in ancient Egyptian and Greek medical writings as well. Also known as apitherapy, the technique is widely used in Eastern Europe, Asia, and South America. The beneficial effects of bee stings can be attributed to mellitinin, an anti-inflammatory agent, known to be hundred times stronger than cortisone. Unfortunately, certain substances in the bee venom trigger allergic reactions which can be life threatening in a sensitized individual. Multiple stings are known to cause hemolysis, kidney injury, hepatotoxicity and myocardial infarction. The toxicity can be immediate or can manifest itself only weeks after the exposure. We describe hepatotoxicity in a 35-year-old female, following bee sting therapy for multiple sclerosis. She presented to our clinic 3 wk after therapy with a history of progressive jaundice. The patient subsequently improved, and has been attending our clinic now for the last 9 mo.

The model uses input based on frequencies and timings of baiting for rodent control for urban, rural and woodland locations......Anticoagulant rodenticides (AR) are a widespread and effective method of rodent control but there is concern about the impact these may have on non-target organisms, in particular secondary poisoning of rodent predators. Incidence and concentration of AR in free-living predators in Denmark is very...... high. We postulate that this is caused by widespread exposure due to widespread use of AR in Denmark in and around buildings. To investigate this theory a spatio-temporal model of AR use and mammalian predator distribution was created. This model was supported by data from an experimental study of mice...

    Intravenous enzyme replacement therapy is a first-line therapy for Gaucher disease type 1, and substrate reduction therapy represents an oral treatment alternative. Both enzyme replacement therapy and substrate reduction therapy are generally used as monotherapies in Gaucher disease. However, one randomized study and several case reports have described combination therapy over short time periods. We report two female Gaucher disease type 1 patients of mainly Anglo-Saxon descent, where combined enzyme replacement therapy and miglustat substrate reduction therapy were administered to overcome refractory clinical symptoms. The first patient was diagnosed at age 17 and developed Gaucher disease-related bone manifestations that worsened despite starting imiglucerase enzyme replacement therapy. After switching to miglustat substrate reduction therapy, her bone symptoms improved, but she developed tremors and eventually switched back to enzyme replacement therapy. Miglustat was later recommenced in combination with ongoing enzyme replacement therapy due to continued bone pain, and her bone symptoms improved along with maintained visceral manifestations. Enzyme replacement therapy was subsequently tapered off and the patient has since been successfully maintained on miglustat. The second patient was diagnosed aged 3, and commenced imiglucerase enzyme replacement therapy aged 15. After 9 years on enzyme replacement therapy she switched to miglustat substrate reduction therapy and her core symptoms were maintained/stable for 3 years. Imiglucerase enzyme replacement therapy was later added as a boost to therapy and her symptoms were subsequently maintained over a 2.3-year period. However, miglustat was discontinued due to her relocation, necessitating an increase in enzyme replacement therapy dose. Overall, both patients benefited from combination therapy. While the majority of Gaucher disease type 1 patients will not need treatment with both substrate reduction therapy

    Patient: Male, 21 Final Diagnosis: Crohn’s disease Symptoms: Intolerance to specific foods • abdominal pain and diarrhea Medication: Human embryonic stem cell therapy Clinical Procedure: Human embryonic stem cell transplantation Specialty: Gastroenterology Objective: Unusual or unexpected effect of treatment Background: Crohn’s disease is a chronic inflammatory disease of the intestines, mainly the colon and ileum, related with ulcers and fistulae. It is estimated to affect 565 000 people in the United States. Currently available therapies, such as antibiotics, thiopurines, and anti-tumor necrosis factor-alpha agents, are only observed to reduce the complications associated with Crohn’s disease and to improve quality of life, but cannot cure the disease. Stem cell therapy appears to have certain advantages over conventional therapies. Our study aimed to evaluate the efficacy of human embryonic stem cell therapy in a patient with Crohn’s disease. Case Report: A 21-year-old male with chief complaints of intolerance to specific foods, abdominal pain, and diarrhea underwent human embryonic stem cell therapy for two months. After undergoing human embryonic stem cell therapy, the patient showed symptomatic relief. He had no complaints of back pain, abdominal pain, or diarrhea and had improved digestion. The patient had no signs and symptoms of skin infection, and had improved limb stamina, strength, and endurance. The condition of patient was stable after the therapy. Conclusions: Human embryonic stem cell therapy might serve as a new optimistic treatment approach for Crohn’s disease. PMID:26923312

    Our experience of 3 cases with dysphagia due to cranial nerve palsy as a late complication after radiation therapy for nasopharyngeal carcinoma (NPC) is herein reported. The cases consisted of two males and one female, ranging in age from 20 to 41 years old at the time of radiation therapy. Two cases received conventional radiation therapy alone while one case was given a combination of chemotherapy and radiotherapy. All patients began to suffer from dysphagia from eight to fifteen weeks after the therapy. All cases had bilateral hypoglossal nerve palsy with several sensory and motor disturbances of the pharynx and larynx. The method of intermittent oral-esophageal tube feeding was performed in one case, however, the other one case had to undergo a total laryngectomy in order to prevent aspiration pneumonia. Recently, the combination of chemotherapy and radiotherapy is frequently performed in order to improve prognosis of NPC. As a result, the occurrence of dysphagia associated with this therapeutic regimen and caused by a late disturbance of the cranial nerve may therefore increase in future. (author)

    1993-03-01

    A 57-year-old male with clival chordoma developed severe hoarseness, dysphagia, and dysphonia 1 month after a second removal of the tumor. Magnetic resonance imaging demonstrated a mass 10 cm in diameter in the region of the middle clivus enhanced inhomogeneously by gadolinium-diethylenetriaminepenta-acetic acid, and a defect in the skull base. There was evidence of compression of the anterior surface of the pons. He received proton irradiation employing a pair of parallel opposed lateral proton beams. The dose aimed at the tumor mass was 75.5 Gy, to the pharyngeal wall less than 38 Gy, and to the anterior portion of the pons less than 30 Gy. Time dose and fractionation factor was calculated at 148. Thirty-one months following treatment, he was free of clinical neurological sequelae. Proton therapy should be considered in treatment planning following initial surgical removal or for inoperable clivus chordoma. (author).

    A patient with nasal reticulum-cell sarcoma received 60 Co irradiation in a total dose of 10,000 rad in 25 fractions and intracarotid arterial transfusion of 5-Fu 4,000 mg. The prognosis was favorable without subjective symptoms for about one year before disturbance in walking and abnormal sensation in legs occurred. Metastasis of tumor was ruled out, and diagnosis of acute radiculoneuritis was made for the reason that the region which exposed to irradiation coincided the level of neurological disturbances which rapidly advanced. This patient received ACTH therapy. Administration of dexamethasone in a dose of 4 mg per day relieved subjective pain and lowered the level of impaired sensation, and arrested progress of motor paralysis. However, the symptoms was exacerbated again after 2 weeks and the decrease of the dose caused an highered the level of impaired and resulted in motor paralysis. Total dose was 171 mg. (Ueda, J.)

    The best time for administering anticoagulation therapy in acute cardioembolic stroke remains unclear. This prospective cohort study of patients with acute stroke and atrial fibrillation, evaluated (1) the risk of recurrent ischemic event and severe bleeding; (2) the risk factors for recurrence and bleeding; and (3) the risks of recurrence and bleeding associated with anticoagulant therapy and its starting time after the acute stroke. The primary outcome of this multicenter study was the composite of stroke, transient ischemic attack, symptomatic systemic embolism, symptomatic cerebral bleeding and major extracranial bleeding within 90 days from acute stroke. Of the 1029 patients enrolled, 123 had 128 events (12.6%): 77 (7.6%) ischemic stroke or transient ischemic attack or systemic embolism, 37 (3.6%) symptomatic cerebral bleeding, and 14 (1.4%) major extracranial bleeding. At 90 days, 50% of the patients were either deceased or disabled (modified Rankin score ≥3), and 10.9% were deceased. High CHA2DS2-VASc score, high National Institutes of Health Stroke Scale, large ischemic lesion and type of anticoagulant were predictive factors for primary study outcome. At adjusted Cox regression analysis, initiating anticoagulants 4 to 14 days from stroke onset was associated with a significant reduction in primary study outcome, compared with initiating treatment before 4 or after 14 days: hazard ratio 0.53 (95% confidence interval 0.30-0.93). About 7% of the patients treated with oral anticoagulants alone had an outcome event compared with 16.8% and 12.3% of the patients treated with low molecular weight heparins alone or followed by oral anticoagulants, respectively (P=0.003). Acute stroke in atrial fibrillation patients is associated with high rates of ischemic recurrence and major bleeding at 90 days. This study has observed that high CHA2DS2-VASc score, high National Institutes of Health Stroke Scale, large ischemic lesions, and type of anticoagulant administered

    Full Text Available The association between nephrotic syndrome (NS and a hypercoagulable state has been demonstrated. Controlling the blood clotting activity may therefore be attractive for patients with nephrosis in terms of thromboembolism prophylaxis. We herein report a 75-year-old woman with minimal change disease who developed pains in the right back, groin, and thigh because of retroperitoneal bleeding during prophylactic anticoagulation with unfractionated heparin. Although this procedure has not been accepted as the standard of care for patients with nephrosis, pharmacologic prophylaxis may already be practiced empirically, as in the present patient. We believe that our experience highlights the pitfalls of such a management in patients with nephrosis, implying the need for a diagnostic strategy for identifying those patients with NS who can benefit from prophylactic anticoagulation. Several concerns that emerged in this case are also discussed.

    Full text: Radioisotopes with medium-energy beta emission and half life of a few days are attractive option for systemic delivery of targeted irradiation. Samarium-153 ethylene diamine tetra-ethylene phosphonale (153Sm-EDTMP), a bone-seeking radiopharmaceutical, provides therapeutic irradiation to osteoblastic osseous lesion. The usual dose of Sm-153 in metastatic disease is 1mCi/Kg (37MBq/Kg) and the dose limiting toxicity is thrombocytopenia. As local radiotherapy has only a limited therapeutic role in the treatment of osteosarcoma, and some types of the tumour portray an unpredictable response to chemotherapy. High dose Sm-153 (30mCi/Kg) was proposed for the target management of recurrent osteosarcoma, this was followed by stem cell transplant (peripheral-blood progenitor, PBPCs). A female child, 10 years old, with polyostotic osteosarcoma with local recurrence in the right hipbone was chosen for therapy. She had left knee prosthesis, right lower limb dis-articulation, and was given chemotherapy in multiple regions. She was subjected to MDP bone scan showing active uptake in an expanding bone lesion in the right hip bone, and was also subjected to MIBI scan, which showed negative uptake. She received 30mCi/Kg Sm-153 (660mCi in total dose), with no major events occurring in the post-injection period. After 10 days the patient went into pancytopenia, which necessitated haematological support. By day 14, there was minimal radiation in the whole body image and the child received her bone marrow transplant. There was marked improvement in the tumour size after 6 weeks of therapy, with improvement in the alkaline phosphatase level (from 1350Iu, before treatment to 350 post treatment). This was confirmed by serial MDP bone scan. High dose Sm-153 with stem cell transplant is considered view a promising method in the management of osteosarcoma. (author)

    Few studies have described physical therapy approaches to provide functional independence and reduce pain in individuals with dystonia. This report describes the physical therapy treatment of a 46-year-old woman diagnosed with idiopathic segmental axial dystonia. For two years, the patient was treated with kinesiotherapy (active and resisted movements and stretching of neck and trunk muscles), abdominal taping (kinesiotaping techniques), functional training, and sensory tricks. She was assessed with parts I, II and III of Toronto Western Spasmodic Torticollis Rating Scale (TWSTRS-I, TWSTRS-II and TWSTRS-III), Berg Balance Scale (BBS), Six-Minute Walk Test (6-MWT), and the motor domain of Functional Independence Measure (FIM-motor) before and after the two-year treatment and after the one year follow-up. Postural control and symmetry improved (TWSTRS-I: from 30 to 18), functional independence increased (TWSTRS-II: from 27 to 15; BBS: from 36 to 46; 6-MWT: from 0 to 480 meters (m); FIM-motor: from 59 to 81), and the pain diminished (TWSTRS-III: from 12 to 5). The functional improvement was retained after one year (TWSTRS-I: 14/35; TWRTRS-II: 12/30; TWRTRS-III: 5/20; BBS: 48/56; 6-MWT: 450 m; FIM-motor: 81/91). This program showed efficacy on providing a better control of the dystonic muscles and thus the doses of botulinum toxin needed to treat them could be reduced. Outcomes support the therapeutic strategies used to deal with this type of dystonia.

    Vitamin K antagonists have been in wide use for over 70 years. Warfarin, the most commonly used vitamin K antagonist, has been shown to be highly effective in treating and preventing thrombosis. Despite this, warfarin has many disadvantages, which has led to the development of a new class of oral anticoagulants targeted to specific coagulation factors designated as target-specific oral anticoagulants (TSOAs). TSOAs include the thrombin inhibitors (dabigatran) and factor Xa inhibitors (rivaroxaban, apixaban). This chapter reviews the disadvantages of warfarin and evaluates both the advantages and disadvantages of the new oral anticoagulants. © 2013 Elsevier Ltd. All rights reserved.

    Increasing attention is being paid to the use of radiation therapy in the management of primary carcinoma of the prostate. Since 1965, radical radiation therapy has been used at Memorial Hospital to treat primary carcinoma of the prostate. Small primary tumors are treated by implantation with radioactive iodine ( 125 I) seeds and larger tumors considered unsuitable for implantation are treated by external supervoltage beam therapy. Fifty patients had been treated by implantation and 30 by external beam therapy at the time of this report. None of the patients treated by implantation developed rectal symptoms. Proctitis developed in all patients treated by external radiation therapy and in half the patients chronic proctitis ensued, accompanied by the passage of mucus. The constant leaking of mucus through the anal sphincter produces irritation of the skin and intermittent attacks of pruritus ani, a discomfiting sequel. Apart from the proctitis, most patients tolerated treatment well, with one notable exception, in whom rectal necrosis developed. This case is described

    A 68-year-old man was referred to our outpatient clinic with left renal cell cancer and bladder cancer. He had undergone combination therapy comprising chemotherapy plus radiation therapy following radical orchiectomy for testicular cancer at the age of 48 years. The right testis could be felt within the scrotum, however the left testis could not. Blood tests showed no abnormality in regard to testicular tumor markers. Urine cytology was class V. Computed tomography revealed a 3.0 x 3.4 cm mass in the left kidney and a 4.5 x 1.5 cm mass in the left wall of the bladder. We made it a priority to treat the bladder cancer which was strongly suspected to be invasive cancer. At first the patient underwent radical cystectomy. Then left partial nephrectomy was carried out. Our case would appear to be the 24th case of triple primary urogenital cancer in Japan that consisted of left testicular cancer, left renal cancer and bladder cancer. Our case was also thought to be a case of secondary cancer that developed following treatment for testicular cancer. (author)

    2016-03-01

    To prevent thrombotic or bleeding events in patients receiving a total artificial heart (TAH), agents have been used to avoid adverse events. The purpose of this article is to outline the adoption and results of a multi-targeted antithrombotic clinical procedure guideline (CPG) for TAH patients. Based on literature review of TAH anticoagulation and multiple case series, a CPG was designed to prescribe the use of multiple pharmacological agents. Total blood loss, Thromboelastograph(®) (TEG), and platelet light-transmission aggregometry (LTA) measurements were conducted on 13 TAH patients during the first 2 weeks of support in our institution. Target values and actual medians for postimplant days 1, 3, 7, and 14 were calculated for kaolinheparinase TEG, kaolin TEG, LTA, and estimated blood loss. Protocol guidelines were followed and anticoagulation management reduced bleeding and prevented thrombus formation as well as thromboembolic events in TAH patients postimplantation. The patients in this study were susceptible to a variety of possible complications such as mechanical device issues, thrombotic events, infection, and bleeding. Among them all it was clear that patients were at most risk for bleeding, particularly on postoperative days 1 through 3. However, bleeding was reduced into postoperative days 3 and 7, indicating that acceptable hemostasis was achieved with the anticoagulation protocol. The multidisciplinary, multi-targeted anticoagulation clinical procedure guideline was successful to maintain adequate antithrombotic therapy for TAH patients.

    Full Text Available Chronic kidney disease has direct implications in nutritional status, causing anorexia and muscular catabolism. These situations are frequent in kidney renal replacement therapy in which nutritional disorders and inflammatory mechanisms associated with therapy often lead to the development of protein-energy wasting. Nutrition therapy has shown an adequate therapeutic strategy to prevent and treat metabolic alterations, reducing surgical and nutritional complication risks in kidney transplantation patients. The current case reports nutritional intervention on a continuous ambulatory peritoneal dialysis patient who was subsequently prescribed to automatic peritoneal dialysis and, finally, kidney transplant from a living donor.

    Severe social withdrawal, called hikikomori, has drawn increased public attention. However, an optimal clinical approach and strategy of treatment has not been well established. Here, we report a case of hikikomori for which an exercise intervention using jogging therapy was effective, showing cerebral hemodynamic improvement. The patient was a 20 year old Japanese male who was hospitalized in order to evaluate and treat severe social withdrawal. Although depressive and anxiety symptoms partially subsided with sertraline alone, social withdrawal persisted due to a lack of self confidence. With his consent, we implemented exercise therapy with 30 minutes of jogging three times a week for three months. We did not change the pharmacotherapy, and his social withdrawal remarkably improved with continuous jogging exercise. Using near infrared spectroscopy to evaluate hemodynamic alteration, bilateral temporal hemodynamics considerably increased after the three-month jogging therapy. Regarding exercise therapy for mental illness, numerous studies have reported the effectiveness of exercise therapy for major depression. This case implied, however, that the applicability of exercise therapy is not limited to major depressive disorder. Jogging therapy may contribute to reinforcing self confidence associated with "resilience" in conjunction with neurophysiological modulation of neural networks.

    Background Condyloma acuminata are soft, skin colored, fleshy warts that are caused by the Human Papilloma Virus (HPV). The disease is highly contagious, can appear singly or in groups, small or large. The incubation period may be from 1?6 months. Although anogenital warts are considered to be sexually transmitted in adults, this may not be the case for children. Genital warts in children may result from several modes of transmission: from the maternal genital tract autoinoculation, from fing...

    The authors present alternatives for the treatment of cardiac arrhythmias. Its detection is based on the use of different methods that record the cardiac electrical activity. The treatment involves intervening in the underlying disorder, antiarrhythmic drugs, stimulation and cardiac defibrillation devices, and, less often, surgery. The technological advances in the last two decades have provided greater efficiency in diagnoses and therapy. Atrial fibrilation patients will benefit from a new set of anticoagulant drugs tested in the past three years. The potential advantages include greater safety and efficacy, as well as convenience for not requiring frequent laboratory controls.

    Full Text Available The case study was conducted between October and January 2015, on 7 dogs of different breeds and ages, which at clinical examination showed varying degrees of lameness. The dogs behavior and state of consciousness, their attitude in standing, decubitus and at walk and the presence of involuntary movements was assessed through inspection. Palpation was used to feel muscular tonus, local temperature and sensibility. Postural reactions were highlighted by carrying out forced positions of each limb, thus highlighting the proprioceptive sensitivity. By testing the spinal reflexes the reactions of the forelimbs and hind limbs were evaluated, seeking the state of normality, or the absence, diminution or exacerbation of these reflexes. Also, diagnostic imaging was performed consisting of simple radiographs, were performed for the cases that entered the clinic. In the case of digital X-rays, X-rays are passing through the subject being examined are filtered, then touch a plate of sensors able to convert signals generated into digital information with an image appear on the computer screen. Interpretation of results was done by assessing the degree of dysplasia, and the Norberg-Olson angle and stage. This study used digital radiography as imaging technique; the device was Rx-M EVO Fujifilm. On the basis of diagnostic imaging and computerized image, diagnosis was established for each case. The treatment protocol with gold implant was the same for all seven cases; the adopted procedure was the "Wiener" procedure, described by Kasper and Zohmann. The procedure began with establishing a set of points associated with the treatment of hip dysplasia, spondylosis, arthritis, and osteochondritis. For the therapeutic protocol to be performed correctly took the dogs were sedated. This was done with medetomidine hydrochloride (Dorbene vet, Pfizer, concentration 1 mg⁄ml, administered in a 0,1mg⁄kg body weight dose. The results were visible after a month from the

    2016-01-01

    Full Text Available Although voriconazole, a triazole antifungal, is a safe drug, treatment with this agent is associated with certain adverse events such as hepatic, neurologic, and visual disturbances. The current report presents two cases, one a 9-year-old boy and the other a 17-year-old girl, who experienced neurologic side effects associated with voriconazole therapy. Our aim is to remind readers of the side effects of voriconazole therapy in order to prevent unnecessary investigations especially for psychological and ophthalmologic problems. The first case was a 9-year-old boy with cystic fibrosis and invasive aspergillosis that developed photophobia, altered color sensation, and fearful visual hallucination. The second case was a 17-year-old girl with cystic fibrosis and allergic bronchopulmonary aspergillosis, and she experienced photophobia, fatigue, impaired concentration, and insomnia, when the dose of voriconazole therapy was increased from 12 mg/kg/day to 16 mg/kg/day. The complaints of the two patients disappeared after discontinuation of voriconazole therapy. Our experience in these patients reminded us of the importance of being aware of the neurologic adverse events associated with voriconazole therapy in establishing early diagnosis and initiating prompt treatment. In addition, although serum voriconazole concentration was not measured in the present cases, therapeutic drug monitoring for voriconazole seems to be critically important in preventing neurologic side effects in pediatric patients.

An observational study on case series with holistic OA therapy. Setting. An outpatient clinic for holistic temporomandibular joint (TMJ therapy under the supervision of the Pain Center, CHA Biomedical center, CHA University. Subjects. Ambulatory patients presenting with diverse chief complaints in the holistic TMJ clinic. Main Measures. Any immediate change in the curvature of cervical spine and the degree of atlantoaxial rotation was investigated in the images of simple X-ray and computed tomography of cervical spine with or without OA. Changes of subjective symptom severity were also analyzed for the holistic OA therapy cases. Results. A total of 59 cases were reviewed. Alignment of upper cervical spine rotation showed an immediate improvement (. Changes of subjective symptom severity also showed significant improvement (. Conclusion. These cases revealed rudimentary clinical evidence that holistic OA therapy may be related to an alleviated symptom severity and an improved cervical spinal alignment. These results show that further researches may warrant for the holistic TMJ therapy.

    Intracranial hemorrhage is the most feared complication of oral anticoagulant treatment. The optimal treatment option for patients with atrial fibrillation who survive an intracranial hemorrhage remains unknown. We hypothesized that restarting oral anticoagulant treatment was associated with a lower risk of stroke and mortality in comparison with not restarting. Linkage of 3 Danish nationwide registries in the period between 1997 and 2013 identified patients with atrial fibrillation on oral anticoagulant treatment with incident intracranial hemorrhage. Patients were stratified by treatment regimens (no treatment, oral anticoagulant treatment, or antiplatelet therapy) after the intracranial hemorrhage. Event rates were assessed 6 weeks after hospital discharge and compared with Cox proportional hazard models. In 1752 patients (1 year of follow-up), the rate of ischemic stroke/systemic embolism and all-cause mortality (per 100 person-years) for patients treated with oral anticoagulants was 13.6, in comparison with 27.3 for nontreated patients and 25.7 for patients receiving antiplatelet therapy. The rate of ischemic stroke/systemic embolism and all-cause mortality (per 100 person-years) for recurrent intracranial hemorrhage, the rate of ischemic stroke/systemic embolism, and all-cause mortality (per 100 person-years) patients treated with oral anticoagulants was 8.0, in comparison with 8.6 for nontreated patients and 5.3 for patients receiving antiplatelet therapy. The adjusted hazard ratio of ischemic stroke/systemic embolism and all-cause mortality was 0.55 (95% confidence interval, 0.39-0.78) in patients on oral anticoagulant treatment in comparison with no treatment. For ischemic stroke/systemic embolism and for all-cause mortality, hazard ratios were 0.59 (95% confidence interval, 0.33-1.03) and 0.55 (95% confidence interval, 0.37-0.82), respectively. Oral anticoagulant treatment was associated with a significant reduction in ischemic stroke/all-cause mortality

    A qualitative approach for describing music psychotherapy treatment is developed. For this purpose we employ the methodological principle of triangulation of perspectives (patient, therapist, independent observers, composers). Our approach is based on the concept of the resonator function describing the perceptive capacity of all participants for effective and relationship-referred significance of the work produced during the treatment. The qualitative method importing and extending the knowledge of the inner context of the case is illustrated by two musical improvisations from the treatment of a female patient suffering from chronic migraine.

    Full Text Available Concetta Crivera,1 Winnie W Nelson,1 Jeff R Schein,1 Edward A Witt2 1Janssen Scientific Affairs, LLC, Raritan, 2Kantar Health, Princeton, NJ, USA Background: Atrial fibrillation (AF is associated with an increased risk of stroke. Anticoagulant (AC therapies are effective at treating AF, but carry with them an increased risk of bleed. Research suggests that a large proportion of AF patients who have high risk of stroke and low risk of bleeding are not currently receiving AC treatment. The goal of this study was to understand the reasons why these patients do not engage in this potentially life-saving treatment.Method: Through a self-report online survey, using validated instruments, 1,184 US adults who self-reported a diagnosis of AF were screened for the risk of stroke and bleed. Of these patients, 230 (19.4% were at high risk of stroke, low risk of bleed, and not currently using an AC treatment, and were asked follow-up questions to assess their reasons for nontreatment, attitudes toward treatment, and attitudes toward dosing regimens.Results: The most common reasons patients stopped AC treatment were concerns regarding bleeding (27.8% and other medical concerns (26.6%, whereas the most common reason cited for not being prescribed an AC in the first place was the use of antiplatelet therapy as an alternative (57.1%. In both cases, potentially erroneous decisions regarding perceived stoke and/or bleeding risk were also a factor. Finally, the largest factors regarding attitudes toward treatment and dosing regimen were instructions from an authority figure (eg, physician, pharmacist and ease of use, respectively.Conclusion: Results suggest that many AF patients who are at high risk of stroke but at low risk of bleed may not be receiving AC due to potentially inaccurate beliefs about risk. This study also found that AF patients place trust in physicians above other factors such as cost when making treatment decisions. Increased education of

    Full Text Available Context: Atypical antipsychotic agents (clozapine, olanzapine have been linked to metabolic effects and acute pancreatitis. Case Report: We reviewed the inpatient and outpatient records of three patients who developed acute pancreatitis while being treated with olanzapine. The mean age of the patients was 37.7 years (range 18–54 years, 2 female, 1 male. No alternative cause of acute pancreatitis was found in two of the three patients. In the remaining patient, olanzapine may have contributed to acute pancreatitis in the setting of hypertriglyceridemia. Olanzapine was discontinued in all instances. Over a mean follow-up of 14 months, one patient has had a relapsing course, but the remaining two patients have been symptom free without recurrence of acute pancreatitis. Conclusions: Our case series adds further support to the potential link between olanzapine use and acute pancreatitis. Close monitoring of metabolic parameters is suggested in patients treated with olanzapine. Alternative antipsychotic agents should be considered in patients at high risk for pancreatitis.

    Food contamination by pathogenic microorganisms has been a serious public health problem and a cause of huge economic losses worldwide. Foodborne pathogenic Escherichia coli (E. coli) contamination, such as that with E. coli O157 and O104, is very common, even in developed countries. Bacterial contamination may occur during any of the steps in the farm-to-table continuum from environmental, animal, or human sources and cause foodborne illness. To understand the causes of the foodborne outbreaks by E. coli and food-contamination prevention measures, we collected and investigated the past 10 years' worldwide reports of foodborne E. coli contamination cases. In the first half of this review article, we introduce the infection and symptoms of five major foodborne diarrheagenic E. coli pathotypes: enteropathogenic E. coli (EPEC), Shiga toxin-producing E. coli/enterohemorrhagic E. coli (STEC/EHEC), Shigella/enteroinvasive E. coli (EIEC), enteroaggregative E. coli (EAEC), and enterotoxigenic E. coli (ETEC). In the second half of this review article, we introduce the foodborne outbreak cases caused by E. coli in natural foods and food products. Finally, we discuss current developments that can be applied to control and prevent bacterial food contamination.

    Broad ischemic stroke is mainly due to a cardiac embolus or to an atheromatous plaque. In young subjects, one of the main causes of ischemic stroke (broad ischemic stroke in particolar) is embolic heart disease including infective endocarditis. Infective endocarditis is a contraindication against the anticoagulant therapy (which is indicated for the treatment of embolic heart disease complicated by ischemic stroke). One neurologic complications of infective endocarditis is ischemic stroke which often occurs in multiple sites. We here report the case of a 44-year old man with afebrile acute onset of severe left hemiplegia associated with a sistolic mitral murmur, who had fever in hospital on day 5 with no other obvious source of infection present. Brain CT scan showed full broad ischaemic stroke of the right middle cerebral artery territory and doppler ultrasound, performed after stroke onset, showed infective endocarditis affecting the small mitral valve. He was treated with 4 weeks of antibiotic therapy without anticoagulant therapy ; evolution was marked by the disappearance of mitral valve vegetations and by movement sequelae involving the left side of the body. In practical terms, our problem was the onset of the fever which didn't accompany or pre-exist patient's deficit, leading us to the misdiagnosis of ischemic stroke of cardioembolic origin. This case study underlines the importance of doppler ultrasound, in the diagnosis of all broad ischemic strokes, especially superficial, before starting anticoagulant therapy.

    Prolongation of clotting times produced by hematin was investigated both in vitro and in vivo. Hematin-derived anticoagulant (HDA) was found to be due to a degradative product or derivative of hematin, and was generated in vitro in standing (aging) aqueous solutions of the parent compound. Generation of HDA in vitro was inhibited by antioxidants. The anticoagulant effect of HDA was inhibited by freshly prepared hematin, fresh Sn-protoporphyrin, imidazole, or the iron chelator desferrioxamine....

    Direct (non-vitamin-K-dependent) oral anticoagulants (DOAC) are given as an alternative to vitamin K antagonists (VKA) to prevent stroke and embolic disease in patients with atrial fibrillation that is not due to pathology of the heart valves. Fatal hemorrhage is rarer when DOACs are given (nonvalvular atrial fibrillation: odds ratio [OR] 0.68; 95% confidence interval [95% CI: 0.48; 0.96], and venous thromboembolism: OR 0.54; [0.22; 1.32]). 48% of emergency trauma patients need an emergency operation or early surgery. Clotting disturbances elevate the mortality of such patients to 43%, compared to 17% in patients without a clotting disturbance. This underscores the impor tance of the proper, targeted treatment of trauma patients who are aking DOAC. This review is based on articles retrieved by a selective search in PubMed and on a summary of expert opinion and the recommendations of the relevant medical specialty societies. Peak DOAC levels are reached 2-4 hours after the drug is taken. In patients with normal renal and hepatic function, no drug accumulation, and no drug interactions, the plasma level of DOAC 24 hours after administration is generally too low to cause any clinically relevant risk of bleeding. The risk of drug accumulation is higher in patients with renal dysfunction (creatinine clearance [CrCl] of 30 mL/min or less). Dabigatran levels can be estimated from the thrombin time, ecarin clotting time, and diluted thrombin time, while levels of factor Xa inhibitors can be estimated by means of calibrated chromogenic anti-factor Xa activity tests. Routine clotting studies do not reliably reflect the anticoagulant activity of DOAC. Surgery should be postponed, if possible, until at least 24-48 hours after the last dose of DOAC. For patients with mild, non-life threatening hemorrhage, it suffices to discontinue DOAC; for patients with severe hemorrhage, there are special treatment algorithms that should be followed. DOACs in the setting of hemorrhage are a

    Recurrence following the surgical treatment of keratocysts of the jaws may present a major problem to the oral surgeon. The surgical treatment of patients with odontogenic keratocysts is concerning the high recurrence rate demanding and difficult. It has been suggested that recurrence is a consequence of technical of microcysts in the mucosa overlying the recurrent lesions. Attemps have been made to reduce this high recurrence rate by improved surgical techniques, such as removal of superadjacent mucosa, smoothing of the osseous wall of the cystic cavity, resection of neighboring parts of the mandible, tanning of the epithelial lining of the cyst with Carnoy's solution and marsupialisation. On the basis of a case report it was the aim of the authors to present the surgical treatment of odontogenic, recurrent keratocysts at the Clinic for Maxillo-Facial Surgery, University Hospital Zurich, from the primary operation following the Brosch-procedure in 1971 up to the latest cystectomy in 2004.

    The primary aim of this case study was to explore the behavioural changes of a paediatric patient in post-traumatic amnesia (PTA) during a music therapy session. A secondary objective was to measure the effect of the music therapy intervention on agitation. Video data from pre, during and post-music therapy sessions were collected and analysed using video micro-analysis and the Agitated Behaviour Scale. The participant displayed four discrete categories of behaviours: Neutral, Acceptance, Recruitment and Rejection. Further analysis revealed brief but consistent and repeated periods of awareness and responsiveness to the live singing of familiar songs, which were classified as Islands of Awareness. Song offered an Environment of Potential to maximise these periods of emerging consciousness. The quantitative data analysis yielded inconclusive results in determining if music therapy was effective in reducing agitation during and immediately post the music therapy sessions. The process of micro-analysis illuminated four discrete participant behaviours not apparent in the immediate clinical setting. The results of this case suggest that the use of familiar song as a music therapy intervention may harness early patient responsiveness to foster cognitive rehabilitation in the early acute phase post-TBI.

    START-Register – Survey on anTicoagulated pAtients RegisTer – is an independent, inception-cohort, observational, collaborative database aimed at recording prospectively the clinical history of adult patients starting anticoagulant treatment for any reason and using whatever drug. In this article we present the START-Register and give cross section baseline data focusing on non valvular atrial fibrillation (NVAF). Participants are asked to insert prospectively consecutive patients recorded as electronic file on the web-site of the registry. Required data are: demographic and clinical characteristics of patients, associated risk factors for stroke and bleeding, laboratory routine data, clinical indication for treatment, expected therapeutic range (in cases of treatment with vitamin K antagonists -VKAs). The follow-up is carried out to record: quality of treatment (for patients on VKAs), bleeding complications, thrombotic events, and the onset of any type of associated disease. To date 5252 patients have been enrolled; 97.6% were on VKAs because direct oral anticoagulants (DOAC) have been available in Italy only recently. The median age was 74 years [interquartile range (IQR) 64-80]; males 53.7%. This analysis is focused on the 3209 (61.1%) NVAF patients. Mean CHADS2 score was 2.1±1.1, CHADSVASc score was 3.1±1.3;median age was 76 years (IQR 70-81); 168 patients (5.3%) had severe renal failure [Creatinine clearance (CrCl) START-Register data shows that two-third of patients who started chronic anticoagulant treatment had NVAF, one-third of them was > 80 years with high prevalence of renal failure.

    The American Society of Regional Anesthesia and Pain Medicine (ASRA) 2012 survey of meeting attendees showed that existing ASRA anticoagulation guidelines for regional anesthesia were insufficient for their needs. Those surveyed agreed that procedure-specific and patient-specific factors required separate guidelines for pain and spine procedures. In response, a guidelines committee was formed. After preliminary review of published complications reports and studies, the committee stratified interventional spine and pain procedures according to potential bleeding risk: low-, intermediate-, and high-risk procedures. The ASRA regional anesthesia anticoagulation guidelines were largely deemed appropriate for the low- and intermediate-risk categories, but the high-risk category required further investigation. The first guidelines specific to interventional spine and pain procedures were published in 2015. Recent reviews evaluating bleeding complications in patients undergoing specific interventional pain procedures, the development of new regional anesthesia and acute pain guidelines, and the development of new anticoagulants and antiplatelet medications necessitate complementary updated guidelines. The authors desired coordination with the authors of the recently updated regional and acute pain anticoagulation guidelines. The latest evidence was sought through extensive database search strategies and the recommendations were evidence based when available and pharmacology driven otherwise. We could not provide strength and grading of these recommendations because there are not enough well-designed large studies concerning interventional pain procedures to support such grading. Although the guidelines could not always be based on randomized studies or on large numbers of patients from pooled databases, it is hoped that they will provide sound recommendations and the evidentiary basis for such recommendations. This publication is intended as a living document to be updated

    This paper describes the study, diagnosis, and course of treatment of a marital couple incorporating Horney theory as a basis for understanding. The case illustrates how fundamental features of Horney theory--character structure, pride positions, attacks on the idealized image, alienated aspects of self, externalization and counter-externalization-can be illuminated in the expanded context of a specific other, the spouse, as background. In a marriage characterized by conflict, omnipresent struggles for authority, and malignantly destructive communication, the wife adopts a position of self-effacement externalizing expansiveness to her husband while the husband adopts an expansive-detached position externalizing both expansiveness and self-effacement to the wife. Externalizations from the wife include a form that has not been described in the psychoanalytic literature of the Horney school: indirect active externalization. As shown, the wife attributes an idealization of her husband to third parties. We observe, too, that the husband's reasonableness and the wife's emotional stridency have the effect of attacking the idealized image of the other. Defenses are mobilized in order to repair hurt pride reactions: for the husband, the wife's stridency is an assault on his sense of himself as a principled, virtous man. For the wife, the husband's reasonableness is experienced as an assault on her sense of herself as a caring wife and mother. In order to block their pride responses and attacks on each other's idealized image, which made conjoint sessions antagonistic and unproductive for a time, a "glass wall" technique was employed for some months that enabled each to speak to the other through me. I struggled against the temptation of siding with the husband's rationality and seeing the wife as secondary. I came to understand that the husband's reasonableness was oppressive for the wife. In order for the wife to feel understood empathically, I needed to fill the role of

    Full Text Available Abstract Background Hemorrhagic events are frequent in patients on treatment with antivitamin-K oral anticoagulants due to their narrow therapeutic margin. Studies performed with acenocoumarol have shown the relationship between demographic, clinical and genotypic variants and the response to these drugs. Once the influence of these genetic and clinical factors on the dose of acenocoumarol needed to maintain a stable international normalized ratio (INR has been demonstrated, new strategies need to be developed to predict the appropriate doses of this drug. Several pharmacogenetic algorithms have been developed for warfarin, but only three have been developed for acenocoumarol. After the development of a pharmacogenetic algorithm, the obvious next step is to demonstrate its effectiveness and utility by means of a randomized controlled trial. The aim of this study is to evaluate the effectiveness and efficiency of an acenocoumarol dosing algorithm developed by our group which includes demographic, clinical and pharmacogenetic variables (VKORC1, CYP2C9, CYP4F2 and ApoE in patients with venous thromboembolism (VTE.

    Hemorrhagic events are frequent in patients on treatment with antivitamin-K oral anticoagulants due to their narrow therapeutic margin. Studies performed with acenocoumarol have shown the relationship between demographic, clinical and genotypic variants and the response to these drugs. Once the influence of these genetic and clinical factors on the dose of acenocoumarol needed to maintain a stable international normalized ratio (INR) has been demonstrated, new strategies need to be developed to predict the appropriate doses of this drug. Several pharmacogenetic algorithms have been developed for warfarin, but only three have been developed for acenocoumarol. After the development of a pharmacogenetic algorithm, the obvious next step is to demonstrate its effectiveness and utility by means of a randomized controlled trial. The aim of this study is to evaluate the effectiveness and efficiency of an acenocoumarol dosing algorithm developed by our group which includes demographic, clinical and pharmacogenetic variables (VKORC1, CYP2C9, CYP4F2 and ApoE) in patients with venous thromboembolism (VTE). This is a multicenter, single blind, randomized controlled clinical trial. The protocol has been approved by La Paz University Hospital Research Ethics Committee and by the Spanish Drug Agency. Two hundred and forty patients with VTE in which oral anticoagulant therapy is indicated will be included. Randomization (case/control 1:1) will be stratified by center.

    Dermatotoxic effects of epicutaneous application of a first-generation anticoagulant, warfarin (WF) were examined in rats. Selected parameters of skin activity were determined 24 h following warfarin application, including metabolic viability of skin explants, some aspects of oxidative activity in skin tissue homogenates and inflammatory/immune relevant activity of epidermal cells from warfarin-treated skin. No changes in skin metabolic viability (MTT reduction) were noted ex vivo following WF application, suggesting the absence of immediate toxicity for skin. In contrast, increased formation of malondialdehyde (MDA), with a decrease in protein and non-protein thiols in homogenates of warfarin-treated skin was demonstrated, pointing to prooxidant activity in warfarin-treated skin. Increased costimulatory activity of epidermal cells isolated from warfarin-exposed skin in Con-A-stimulated T-cell activation/proliferation assay was noted, reflecting proinflammatory and immune-modulating capacity of warfarin for epidermis. No evident differences in skin histology between control and warfarin-treated skin were found at that time point, while striking changes in tissue integrity, cellularity and appearance 72 h following WF application were noted. The observed histological picture probably reflects a regenerative/inflammatory program related to oxidant/inflammation-type warfarin-evoked injury to the skin. Presented data demonstrate the potential of epicutaneously applied warfarin to modulate local skin activity in rats

    In 1994, the, French National Quality Control Group for Hematology, Etalonorme, conducted a large-scale interlaboratory survey concerning the detection of lupus anticoagulants (LA) involving all the 4,500 French laboratories. Each laboratory received the same batch of a lyophilized citrated plasma (94B3) prepared from a patient with LA that had been confirmed by all the techniques used in the intralaboratory study. In the interlaboratory survey, the screening test was activated partial thromboplastin time (APTT); mean APTT calculated from the results reported by 4,029 labs was prolonged (clotting ratio = 1.44) with a large dispersion (coefficients of variation = 18.8%). APTT of the mixture 94B3 + normal plasma were performed by 2,698 laboratories. No correction of APTT was obtained (R = 1.36, Rosner index = 24) with a wide variation between reagents (17 kaolin. This survey allowed Etalonorme to inform French biologists and draft an educational program for the biologic detection of LA and the identification of its mechanism of action.

  4. Play therapy: a case-based example of a nondirective approach.

    2008-10-01

    Play therapy is a treatment modality in which the therapist engages in play with the child. Its use has been documented in a variety of settings and with a variety of diagnoses. Treating within the context of play brings the therapist and the therapy to the level of the child. By way of an introduction to this approach, a case is presented of a six-year-old boy with oppositional defiant disorder. The presentation focuses on the events and interactions of a typical session with an established patient. The primary issues of the session are aggression, self worth, and self efficacy. These themes manifest themselves through the content of the child's play and narration of his actions. The therapist then reflects these back to the child while gently encouraging the child toward more positive play. Though the example is one of nondirective play therapy, a wide range of variation exists under the heading of play therapy.

    We report a case of Cotard's syndrome associated with psychotic symptoms. A 27-year-old man was admitted to hospital with the diagnosis of schizophreniform disorder. His presenting symptoms, which had started 1 month before hospital admission, were somatic delusions of gastrointestinal and cardiovascular malfunction and the absence of a stomach, which resulted in a decrease in weight from 75 kg to 63 kg in 1 month. Cranial computed tomographic images showed dilatation of the lateral and third ventricles, whereas magnetic resonance imaging revealed central atrophy and lateral ventricle dilatation. Single- photon emission computed tomography demonstrated left temporal, left frontal and left parietal hypoperfusion. The patient did not respond to antipsychotic therapies, but he was successfully treated with electroconvulsive therapy. This report emphasizes that Cotard's syndrome may be accompanied by lesions of the left hemisphere and that electroconvulsive therapy could be the first-line therapy in such patients with psychotic disorder.

    We report a case of a 65-year-old female patient after replacement of aortic and mitral valve with mechanical prostheses and implantation of a pacemaker hospitalized in our clinic due to acute coronary syndrome complicated with cardiac arrest due to ventricular fibrillation. The electrocardiogram performed on admission showed signs of myocardial infarction with concomitant ventricular pacing. After successful resuscitation the coronary angiography was performed, which showed occlusion of the left circumflex artery (LCx) by thrombus. On the basis of intravascular ultrasound imaging the presence of vulnerable plaque, parietal thrombus and dissection of LCx were excluded. It suggested that occlusion of the LCx resulted from its embolism by left-sided heart thrombus due to subtherapeutic oral anticoagulation. In this case suboptimal anticoagulation was partially iatrogenic. Two weeks before the patient had been given vitamin K intravenously due to indeterminable international normalized ratio (INR) level, which caused transient resistance to oral anticoagulants. This case report illustrates tragic difficulties in the treatment with vitamin K antagonists, which concern as many as 2/3 of anticoagulated patients. These troubles contributed to the search for new, more efficient and safer anticoagulants. There are two classes of new oral anticoagulant drugs, which do not require monitoring of coagulation: direct thrombin inhibitors (e.g. dabigatran) and factor Xa inhibitors (e.g. rivaroxaban). In spite of their proven efficacy in the prevention of ischaemic stroke related to atrial fibrillation and prevention or treatment of deep vein thrombosis and pulmonary embolism, the use of new oral anticoagulants for the treatment of patients with mechanical valve prostheses needs further research.

    According to DSM-IV, personality disorder constitutes a class only when personality traits are inflexible and maladaptive and cause either significant functional impairment or subjective distress. Classical treatment of choice for personality disorders has been psychotherapy and/or psychopharmacotherapy. Our study is to determine if subjects with antisocial personality disorders will benefit from quantitative EEG (qEEG) guided neurofeedback treatment. Thirteen subjects (9 male, 4 female) ranged in age from 19 to 48 years. All the subjects were free of medications and illicit drugs. We excluded subjects with other mental disorders by clinical assessment. Psychotherapy or psychopharmacotherapy or any other treatment model was not introduced to any of the subjects during or after neurofeedback treatment. For the subject who did not respond to neurofeedback, training was applied with 38 sessions of LORETA neurofeedback training without success. Evaluation measures included qEEG analysis with Nx Link data base, MMPI, T.O.V.A tests and SA-45 questionaries at baseline, and at the end of neurofeedback treatment. Lexicor qEEG signals were sampled at 128 Hz with 30 minutes-neurofeedback sessions completed between 80-120 sessions depending on the case, by Biolex neurofeedback system. At baseline and after every 20 sessions, patients were recorded with webcam during the interview. Twelve out of 13 subjects who received 80-120 sessions of neurofeedback training showed significant improvement based on SA-45 questionaries, MMPI, T.O.V.A. and qEEG/Nx Link data base (Neurometric analysis) results, and interviewing by parent/family members. Neurofeedback can change the view of psychiatrists and psychologists in the future regarding the treatment of personality disorders. This study provides the first evidence for positive effects of neurofeedback treatment in antisocial personality disorders. Further study with controls is warranted.

    Full Text Available Aim: the study of the efficacy of methotrexate in patients with the "escape effect" during the ustekinumab therapy. Materials and Methods. The results of methotrexate at a dose of 15-20mg/week in treatment of 4 patients receiving biologic and developed "escape effect". Ustekinumab is used as a hypodermic injection at a dose of 45 mg for a body weight of a patient no more than 100 kg, and 90 mg of body weight over 100 kg, at the zero week, the 4th week and then every 12 weeks. Patients control meets the standard management of patients in biological therapy. Results. The study shows that in the case of the resistance progressing when applying preparations of biological therapy, methotrexate is useful at a dose of 15-20mg/week for up to 6 months. The combined use of biologic therapy and methotrexate in the treatment of patients with psoriasis vulgaris, "escape effect" contributes to the marked regression of clinical symptoms and allows to control the process long enough, which is confirmed by the dynamics of the index PASI, BRS and DLQI. The combined method is highly safe, as evidenced by the lack of inhibition of hematopoiesis, the normal level of hepatic transaminases and serum creatinine, which greatly improves patient compliance in this type of therapy. Conclusion. The article presents the data of the combined application of biological medication therapy (ustekinumab and methotrexate for the treatment of patients with the common form of psoriasis vulgaris. In the case of the development of resistance of biological therapy recommended the appointment of methotrexate. The combined use of methotrexate and biologic therapy in the treatment of patients with psoriasis vulgaris contributes to marked regression of clinical symptoms and allows to control the process for a long time.

  13. Management of novel oral anticoagulants in emergency and trauma surgery.

    2016-08-01

    The compelling safety, efficacy and predictable effect of novel oral anticoagulants (NOACs) is driving a rapid expansion in their therapeutic indications. Management of the increasing number of patients on those new agents in the setting of emergency or trauma surgery can be challenging and the absence of specific reversal agents has been a matter of concern. This review summarises the key principles that underpin the management of those patients with a particular emphasis on the recent development of specific antidotes. As of 2015, a new line of antidotes, specific for these drugs, are at different stages of their development with their release imminent. However, as NOACs are innately reversible due to their short half-life, the use of reversal agents will probably be restricted to a few exceptional cases. Post-marketing surveillance will be paramount to better clarify the role of these promising drugs. Management of patients on NOACs in the context of emergency or trauma surgery relies on best supportive care in combination with the blood products and/or specific antidotes as required. Familiarity with the new reversal agents is essential but further evidence on their indications, safety and efficacy as well as consensus guidelines are warranted prior to widespread adoption.

    -up there were no new patients diagnosed with an endocrine abnormality; however, 13 out of 22 patients had an increase in the number of endocrine deficiencies requiring hormone replacement. At presentation, 14 patients showed evidence of growth retardation. At follow-up there were no new cases of growth failure in the remaining patients. Conclusions: Germinomas are highly curable with RT alone. Lower doses of RT to the craniospinal axis without chemotherapy appear to produce equally effective DFS and OS as do higher doses of RT or combination chemotherapy and RT. Craniospinal RT may be indicated for patients with MMG or patients with evidence of spinal seeding. Long-term effects of growth retardation, and other endocrine deficiencies appear to be correlated with disease at presentation rather than solely with treatment

  9. Idarucizumab for Reversing Dabigatran-Induced Anticoagulation: A Systematic Review.

    Science.gov (United States)

    Thibault, Nathan; Morrill, Amanda M; Willett, Kristine C

    The approval of the oral direct thrombin inhibitor, dabigatran etexilate, gave patients an alternative to oral anticoagulation with warfarin. Like all anticoagulants, the primary adverse event (AE) associated with dabigatran is bleeding. Until the FDA approval of idarucizumab, there had been no reversal agent for dabigatran-induced anticoagulation in patients with life-threatening or uncontrollable bleeding, or those requiring emergent procedures. The primary purpose of this review is to summarize the safety and efficacy of idarucizumab, a monoclonal antibody fragment, and its use as a reversal agent for dabigatran. A literature search was conducted through MEDLINE (1946 to November week 1 2015) and Embase (1980-2015 week 46) using the search term idarucizumab. Clinicaltrials.gov was consulted for a comprehensive list of ongoing and completed studies. Additional studies were identified through bibliographical citations. Clinical trials in animals and humans published in English evaluating the safety and efficacy of idarucizumab for reversal of anticoagulant treatment with dabigatran were included for review. Idarucizumab has been shown to significantly reverse the anticoagulant effects of dabigatran in both healthy volunteers and patients requiring a reversal agent because of either overt bleeding or an emergency surgery or invasive procedure. The most common AEs were headache, nasopharyngitis, back pain, skin irritation, hypokalemia, delirium, constipation, pyrexia, and pneumonia. Deaths reported in idarucizumab studies were attributed to either the index event or a preexisting comorbidity. Most adverse effects were minor, but 21 serious AEs have been reported in the published data including thrombotic events. Given the increased use of direct oral anticoagulants, such as dabigatran, a need for specific reversal agents exists. Idarucizumab has been shown to be safe and effective in the reversal of dabigatran-induced anticoagulation in patients requiring emergent

  10. Clinical Case Reporting in the Peer-Reviewed Physical Therapy Literature: Time to Move Toward Functioning.

    Davenport, Todd E

    2015-12-01

    Physical therapists increasingly are contributing clinical case reports to the health literature, which form the basis for higher quality evidence that has been incorporated into clinical practice guidelines. Yet, few resources exist to assist physical therapists with the basic mechanics and quality standards of producing a clinical case report. This situation is further complicated by the absence of uniform standards for quality in case reporting. The importance of including a concise yet comprehensive description of patient functioning in all physical therapy case reports suggest the potential appropriateness of basing quality guidelines on the World Health Organization's International Classification of Functioning Disability and Health (ICF) model. The purpose of this paper is to assist physical therapists in creating high-quality clinical case reports for the peer-reviewed literature using the ICF model as a guiding framework. Along these lines, current recommendations related to the basic mechanics of writing a successful clinical case report are reviewed, as well and a proposal for uniform clinical case reporting requirements is introduced with the aim to improve the quality and feasibility of clinical case reporting in physical therapy that are informed by the ICF model.

  11. The role of heparin in sepsis: much more than just an anticoagulant.

    Science.gov (United States)

    Li, Xu; Ma, Xiaochun

    2017-11-01

    Despite progress in antibiotic treatment, mechanical ventilation, fluid resuscitation and blood glucose maintenance, sepsis remains a cause of high mortality in the intensive care unit to date, there are no proven treatment strategies for the routine management of septic patients. The extensive interaction between inflammation and coagulation contributes to the basic pathophysiology of sepsis. Thus, the agents that attenuate the activation of both inflammation and coagulation may improve the outcome in sepsis. Apart from the well-known anticoagulant effects of heparin, it also possesses various immunomodulatory properties and protects glycocalyx from shedding. Hence, heparin seems to be such an agent. Immunothrombosis plays an important role in early host defence against bacterial dissemination, thus the proper timing for anticoagulant therapy should be determined. We review the available experimental and clinical data supporting the use of heparin in sepsis. At this time the use of heparin in the treatment of sepsis is conflicting.

    increasingly more frequent. With the lower probability of promoting vascular damage the ultrasound has become an interesting tool in peripheral nerve blocks especially in patients in use of anticoagulants or with coagulopathies. The objective of this article was to report two cases in which ultrasound-guided sciatic and femoral nerve blocks were performed in anticoagulated patients. CASE REPORTS: In the first case, the patient underwent amputation of the left forefoot due to necrosis and signs of infection, and in the second case, surgical cleaning of the left knee. Patients had changes in coagulation with levels of activity of prothrombin and activated partial thromboplastin time above normal limits. Both patients underwent ultrasound-guided femoral and sciatic nerve blocks, evolving without motor or sensorial changes in the territories of those nerves and without hematoma at the site of puncture. CONCLUSIONS: Anticoagulation imposes some restrictions to classical regional anesthetic techniques. With the development of ultrasound equipment and methods, it is now possible to accurately identify vascular and neural structures. This allows ultrasound-guided puncture to be more precise, both to achieve the area of interest and to minimize the risks of accidental vascular damage. Until now, peripheral block was not recommended in anticoagulated patients or in those with coagulopathies. However, considering that few reports on ultrasound-guided regional blocks in coagulopathies can be found in the literature, the safety of this technique in this condition has yet to be established.

    Rodents are known to affect human society globally in various adverse ways, resulting in a widespread demand for their continuous control. Anticoagulant rodenticides (ARs) have been, and currently remain, the cornerstone of rodent control throughout the world. Although alternative control methods exist, they are generally less effective. ARs work by affecting vitamin K metabolism, thereby preventing the activation of blood clotting factors and eventual coagulopathy. Since ARs are non-selective, their undoubted benefits for rodent control have to be balanced against the environmental risks that these compounds pose. Although they have been used for decades, pharmacokinetic and toxicokinetic data are mainly available for laboratory mammals and have concentrated on acute effects. Limited information is available on chronic exposure scenarios and for wildlife species. Important gaps exist in our understanding of the large inter- and intra-species differences in sensitivity to ARs, especially for non-target species, and in our knowledge about the occurrence and importance of sub-lethal effects in wildlife. It is clear that mere presence of AR residues in the body tissues may not indicate the occurrence of effects, although unequivocal assessment of effects under field conditions is difficult. Ante-mortem symptoms, like lethargy, subdued behaviour and unresponsiveness are generally not very specific as is true for more generic post-mortem observations (e.g. pallor of the mucous membranes or occurrence of haemorrhages). It is only by combining ante or post-mortem data with information on exposure that effects in the field may be confirmed. We do know however that a wide variety of non-target species are directly exposed to ARs. Secondary exposure in predators is also widespread although there is limited information on whether this exposure causes actual effects. Exposure is driven by ecological factors and is context specific with respect to spatial habitat configuration

    A 20-year-old man received 60 Gy of radiation therapy after partial removal of craniopharyngioma. The patient had been well and follow-up CT scans did not show any aggravation for 16 years. Since his activity gradually diminished, he underwent an MRI at the age of 36 which revealed and abnormal mass on the corpus callosum. The mass lesion progressively enlarged thereafter, and was diagnosed as anaplastic astrocytoma by a stereotactic biopsy. He was treated with interferon, however, died at the age of 37. Review of the literature disclosed 19 other cases of glioma following radiation therapy for sellar/parasellar tumors. Characteristic features of these cases included (1) lowness of age compared to common glioma cases, (2) tendency to be malignant, (3) tendency to occur in areas where significant doses of radiation had been received previously.

    External compression of the left iliac vein against the fifth lumbar vertebra by the right iliac artery (May and Thurner Syndrome) is a well known anatomic variant. We identified a rare case of May-Thurner syndrome associated with crossed fused renal ectopia on the left side. The patient presented with complete thrombosis of the left common iliac vein down to the popliteal vein. He was treated with catheter directed thrombolysis followed by anticoagulant therapy.

    Full Text Available Development of manic symptoms during treatment with atypical antipsychotics can be a troublesome side effect that has been described with most atypical antipsychotics. However, reports of amisulpride induced mania have been rare. Here, we report the case of an 18-year-old male patient diagnosed with schizophrenia, who developed manic symptoms while on treatment with amisulpride. While previous reports have described occurrence of mania within days to three months of treatment with amisulpride, we report a case where manic symptoms occurred after around eight months of therapy. We have also attempted to describe the possible risk factors based on the available case studies.

    A novel approach for therapeutic drug monitoring of oral anticoagulants (OA) in clinical samples is reported, based on a NP-based biobarcode assay. The proposed strategy uses specific antibodies for acenocumarol (ACL) covalently bound to magnetic particles (pAb236-MP) and a bioconjugate competitor (hACL-BSA) linked to encoded polystyrene probes (hACL-BSA-ePSP) on a classical competitive immunochemical format. By using this scheme ACL can be detected in low nM range (LOD, 0.96 ± 0.26, N = 3, in buffer) even in complex samples such as serum or plasma (LOD 4 ± 1). The assay shows a high reproducibility (%CV 1.1 day-to-day) and is robust, as it is demonstrated by the fact that ACL can be quantified in complex biological samples with a very good accuracy (slope = 0.97 and R 2 = 0.91, of the linear regression obtained when analyzing spiked vs measured values). Moreover, we have demonstrated that the biobarcode approach has the potential to overcome one of the main challenges of the multiplexed diagnostic, which is the possibility to measure in a single run biomarker targets present at different concentration ranges. Thus, it has been proven that the signal and the detectability can be modulated by just modifying the oligonucleotide load of the encoded probes. This fact opens the door for combining in the same assay encoded probes with the necessary oligonucleotide load to achieve the detectability required for each biomarker target.

    Introduction Parkinson’s disease (PD) is a complex neurological disorder. The disease is progressive and, in time, results in severe disability. Many patients turn to massage in an attempt to alleviate symptoms of pain and rigidity, though the effects of massage with respect to PD are not well studied. This case adds one more instance in which massage therapy has provided temporary respite from resting tremor, one unrelenting symptom of PD. Objective To determine if massage therapy can produce favorable outcomes with respect to the severity of rigidity and tremor in a patient with PD. Case Presentation A 63-year-old female patient with idiopathic, long-standing, Hoehn-Yahr Stage 4 PD was treated with massage therapy five times over the course of six weeks. A SPES/SCOPA Motor Impairments rating scale was used to measure rigidity and tremor pre- and post-treatment, to gauge treatment effectiveness. The massage treatments consisted of deep longitudinal stroking, muscle squeezing techniques, passive range of motion movements, and general relaxation techniques to encourage a soothing environment while promoting a decrease in muscular tone and hyperactivity. Massage therapy administration was by a student near the end of her two-year diploma. Results The results obtained indicated that massage therapy treatment had a positive effect on reducing resting and postural tremor in a patient with long-standing PD. The treatment was also effective in temporarily reducing rigidity during treatment, but did not produce a lasting effect. Conclusion Further study is required; however, the results of this case were consistent with the limited research available on the subject of massage therapy and Parkinson’s disease, in that positive change with respect to tremor—and to a lesser degree, rigidity—were achieved with focused, intentional treatment.

    Acute low back pain, radiculopathy, and associated disabilities have a prevalence of 2% in the United States, which represents a significant health problem and a major cause of workplace absence. The condition primarily affects 25- to 45-year-old men and women. Epidural steroid injections (ESIs) are commonly administered to relieve this pain and improve mobility without surgery. This case report presents issues related to the treatment of an epidural hematoma in an 87-year-old man receiving long-term anticoagulant therapy. It reviews the risks, benefits, side effects, complications, and contraindications to ESI and the American Society of Regional Anesthesia consensus recommendations for the performance of neuraxial procedures in patients receiving anticoagulant therapy. It is imperative that any provider who performs ESIs know the risks, benefits, complications, and contraindications for this procedure. Practitioners must also be able to recognize and manage or appropriately refer patients having immediate or delayed complications related to the placement of an ESI.
