Anticoagulant therapy is the mainstay for the treatment of venous thromboembolism (VTE). Consequently, evidence for or against indefinite anticoagulation in different subgroups of patients with VTE is based on estimating the absolute reduction in recurrent VTE and the increase in major bleeding with indefinite anticoagulation, and then estimating their combined effect on mortality. Consistent with the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) nomenclature and the ACCP guidelines, a strong recommendation indicates a high degree of confidence that following the recommendation will result in substantial benefits for most patients.1,60  Strong recommendations, which are usually based on high-quality evidence, have been described as “just do it”; given the evidence, almost all patients would chose that option (ie, decisions are not sensitive to patient values and preferences). This is called a deep vein thrombosis, or DVT. For patients with extensive DVT in whom thrombolysis is considered appropriate, the ASH guidelines suggest using catheter-directed thrombolysis over systemic thrombolysis. Also, because a recurrence is 3 times as likely to be a PE if the initial event was a PE rather than a DVT, case fatality for recurrent VTE may be substantially higher (perhaps double) when the initial VTE was a PE.27,28Â, Nonfatal events are also important: (1) PE, DVT, and bleeding are distressing for patients29,30  and costly31 ; (2) recurrent DVT, especially in the same leg, increases risk and severity of the postthrombotic syndrome (PTS)31,32 ; and (3) recurrent PE may cause chronic cardiopulmonary impairment.1Â, This decision is dominated by the risk of recurrent VTE. Enoxaparin in the treatment of deep vein thrombosis with or without pulmonary embolism: an individual patient data meta-analysis. The Duration of Anticoagulation Trial Study Group. Furthermore, the trials that compared 3 months with 6 to 12 months of anticoagulation (mostly patients with unprovoked VTE)6,10-12  found more major bleeding (relative risk, 2.49; 95% CI, 1.20-5.16) with longer therapy.1  For these reasons, if patients with a first unprovoked proximal DVT or PE are not treated indefinitely, we generally stop anticoagulants at 3 rather than 6 months. Treatment is 3 – 6 months if a trigger is identified (e.g. Optimum duration of anticoagulation for deep-vein thrombosis and pulmonary embolism. The typical duration of treatment for a DVT is at least six months. It can detect blockages or blood clots in the deep veins. Inflammatory bowel disease is a risk factor for recurrent venous thromboembolism. Risk assessment of recurrence in patients with unprovoked deep vein thrombosis or pulmonary embolism: the Vienna prediction model. Identifying unprovoked thromboembolism patients at low risk for recurrence who can discontinue anticoagulant therapy. These are also factors that support treatment of 3 rather than 6 months in patients who are not treated indefinitely. These results were disappointing, with a high rate of recurrent VTE events, likely secondary to inadequate duration of treatment for initial DVT, as well as low sensitivity of IPV in detecting residual thombus. The concept of 2 overlapping phases of anticoagulation for VTE has important management implications. Solve your problem quick & easy with online consultation. If, however, the risk of recurrence after completion of active treatment remains unacceptably high, indefinite anticoagulation is indicated (termed “extended anticoagulation” in the ACCP guidelines1 ). Reduce your chances of another DVT. Most commonly, venous thrombosis occurs in the \"deep veins\" in the legs, thighs, or pelvis (figure 1). You'll also have a physical exam so that your doctor can check for areas of swelling, tenderness or discoloration on your skin. Patient values and preferences in decision making for antithrombotic therapy: a systematic review: Antithrombotic Therapy and Prevention of Thrombosis, 9th ed: American College of Chest Physicians Evidence-Based Clinical Practice Guidelines. A meta-analysis. Duration of anticoagulation treatment and long-term anticoagulation for secondary prevention. DVT clinic (patient to take 10 mg stat and 10 mg 12 hours later). Influence of hereditary or acquired thrombophilias on the treatment of venous thromboembolism. Importance of clarifying patients’ desired role in shared decision making to match their level of engagement with their preferences. The combination of anticoagulation plus aspirin increases the risk of bleeding without clear evidence of benefit for patients with stable cardiovascular disease. Pulmonary Hypertension and Venous Thromboembolism. In patients with an unprovoked DVT of the leg (isolated distal or proximal) or PE, we recommend treatment with anticoagulation for at least 3 months over treatment of a shorter duration (Grade 1B), and we recommend treatment with anticoagulation for 3 months over treatment of a longer time-limited period (eg, 6, 12, or 24 months) (Grade 1B). Comparison of 3 and 6 months of oral anticoagulant therapy after a first episode of proximal deep vein thrombosis or pulmonary embolism and comparison of 6 and 12 weeks of therapy after isolated calf deep vein thrombosis. Systematic review: case-fatality rates of recurrent venous thromboembolism and major bleeding events among patients treated for venous thromboembolism. VTE provoked by a reversible risk factor, or a first unprovoked isolated distal (calf) deep vein thrombosis (DVT), has a low risk of recurrence and is usually treated for 3 months. Duration of anticoagulant therapy for deep vein thrombosis and pulmonary embolism. If the intention is to use d-dimer testing in this way, it should first be established with the patient that d-dimer results will influence treatment decisions (Figure 1). 3.1.4. has served as a consultant to Boehringer Ingelheim and to Bayer Inc. E.A.A. It takes about 3 months to complete “active treatment” of venous thromboembolism (VTE), with further treatment serving to prevent new episodes of thrombosis (“pure secondary prevention”). Indefinite anticoagulation refers to continued treatment without a scheduled stopping date; treatment is stopped only if the risk of bleeding increases or anticoagulation becomes excessively burdensome. Treatment of cancer-associated thrombosis. DOAC therapy is preferred over vitamin K antagonists (VKAs) for most patients without severe renal insufficiency (creatinine clearance <30 ml/min), moderate-severe liver disease, or antiphospholipid antibody syndrome. Which patients should stop anticoagulants at 3 months and which should remain on anticoagulants indefinitely? Apixaban and rivaroxaban should not be used in pregnancy, and are not recommended in Give apixaban oral 10mg twice daily for the first 7 days and then 5mg twice daily for the remaining duration of acute treatment (i.e. Extended oral anticoagulant therapy after a first episode of pulmonary embolism. To diagnose deep vein thrombosis, your doctor will ask you about your symptoms. Get your query answered 24*7 with Expert Advice and Tips from doctors for Dvt treatment duration | Practo Consult 3 or 6 months). You may have an injection of an anticoagulant (blood thinning) medicine called heparin while you're waiting for an ultrasound scan to tell if you have a DVT. Long-term, low-intensity warfarin therapy for the prevention of recurrent venous thromboembolism. Costs (ie, to patients, health care systems, third-party payers) and available treatment options (eg, licensing) may further influence decisions at a patient or societal level. The ASH assembled a multidisciplinary writing committee to provide evidence-based guidelines for management of DVT and PE, which occur 300,000-600,000 times annually in the United States. Many patients with a first unprovoked proximal DVT or PE are treated indefinitely (see “Unprovoked VTE: recommendations”).1  Reasons not to treat indefinitely include a lower than average risk of recurrence, a high risk of bleeding, and patient preference. This applies if a woman would choose to remain on anticoagulants if she had a first-year recurrence risk of 10%, but would choose to stop treatment if this risk was 5%; if a 10% risk would not justify staying on treatment, anticoagulants should be stopped without d-dimer testing. Direct and indirect comparisons have found similar reductions in recurrent VTE with extended anticoagulation using dabigatran (150 mg twice-daily),17  rivaroxaban (20 mg daily),18  or apixaban (2.5 mg or 5 mg twice-daily).19,20  Extended treatment with low-molecular-weight-heparin (LMWH) is also very effective, and is more effective than a VKA in cancer patients.1,21,22Â, Anticoagulation with VKAs is associated with about a 2.6-fold increase in major bleeding (based on 4 studies13-16 : relative risk, 2.63; 95% CI, 1.02-6.78). Risk of recurrence after venous thromboembolism in men and women: patient level meta-analysis. Is Dvt treatment duration your major concern? VTE associated with active cancer, or a second unprovoked VTE, has a high risk of … Placement of an iliac vein stent does not necessarily mean that patients should be treated indefinitely, but residual thrombus or extrinsic compression encourages that option.Â. Patients were treated for 6 months and were followed-up for 30 days after they stopped treatment. Consequently, VTE should generally be treated for either 3 months or indefinitely (exceptions will be described in the text). Evidence suggests that heterozygosity for the Leiden variant has at most a modest effect on risk for recurrent thrombosis after initial treatment of a first VTE. These studies were designed to assess efficacy of treatment for prevention of recurrent VTE; they were not powered to assess mortality. Warfarin Optimal Duration Italian Trial Investigators. Thrombolysis is reasonable to consider in patients presenting with limb-threatening DVT (phlegmasia cerulea dolens) or for select younger patients at low bleeding risk with iliofemoral DVT. Deep venous thrombosis (DVT) is a common condition estimated to affect around 100 000 patients each year in the UK.1 It can lead to death through pulmonary embolism and rarely limb loss through phlegmasia cerulea dolens. If for long-term anticoagulation, the dose of apixaban should be reduced to 2.5mg twice daily after 6 months. Currently, the recommended treatment duration ranges from a minimum of 3 months to a maximum of lifelong treatment. The duration of oral anticoagulant therapy after a second episode of venous thromboembolism. Some patients resent, whereas others are reassured by, anticoagulant therapy. This clot can limit blood flow through the vein, causing swelling and pain. 3 Prior studies have shown clearly that a short duration of therapy (4-6 weeks) is of insufficient duration and increases the risk of recurrent VTE by approximately 50%. Randomization of patients to different time-limited durations of anticoagulation, with subsequent follow-up to determine the rate of recurrence in each group after anticoagulants are stopped, provides the best evidence on the duration required to complete “active treatment.” These trials are summarized in the following sections. Extended Low-Intensity Anticoagulation for Thrombo-Embolism Investigators. In severe cases of DVT, where a clot must be surgically removed, there may be additional recovery time. Three clinical prediction rules have been developed to estimate the risk of recurrence in patients with unprovoked VTE. Therefore, patients with VTE are usually treated for either 3 months or indefinitely. Brief guidance is given below. In patients with an unprovoked DVT of the leg (isolated distal [see remark] or proximal), we recommend treatment with anticoagulation for at least 3 months over treatment of a shorter duration (Grade 1B). As the acute DVT is often severe, and symptoms may have become chromic (ie, PTS), anticoagulation for 6 mo is often desirable, and patients may be more likely to opt for indefinite anticoagulation if the DVT was provoked by a minor reversible risk factor. Estrogens serve as a reversible risk factor for VTE. On discharge they will require maintenance treatment with an oral anticoagulant for at least 3 months (provided there are no contraindications such as cancer or pregnancy). Effect of patient’s sex on risk of recurrent venous thromboembolism: a meta-analysis. It may be acceptable, however, for patients to remain on oral contraceptives during anticoagulant therapy. More recent studies have been directed at the … Nevertheless, several facts have been highlighted in the past two decades that should help establish guidelines based on evidence rather than on variable opinions of leaders in the field. Usual Adult Dose for Deep Vein Thrombosis Prophylaxis after Hip Replacement Surgery. UW Medicine Anticoagulation Services Sept 2014 STOP AFTER 3 MONTHS RECOMMENDATIONS FOR DURATION OF ANTICOAGULANT THERAPY FOLLOWING VTE This algorithm is intended as a general guidance, not a protocol, for determining the duration … VTE provoked by a reversible risk factor, or a first unprovoked isolated distal (calf) deep vein thrombosis (DVT), has a low risk of recurrence and is usually treated for 3 months. Risk of major bleeding of 0.8% for each of the 5 years. Venous means related to veins. DVT treatment options include: Blood thinners. Treatment goals for deep venous thrombosis include stopping clot propagation and preventing the recurrence of thrombus, the occurrence of pulmonary embolism, and the development of pulmonary hypertension, which can be a complication of multiple recurrent pulmonary emboli. surgery, hospitalization, OCPs) and has been removed. evidence review D: pharmacological treatment in people with suspected or confirmed deep vein thrombosis and/or pulmonary embolism (for recommendations 1.4.1 and 1.4.7 to 1.4.11). Treatment duration for DVT / PE. The thrombus is then called an embolus.. A pulmonary embolus occurs when … In severe cases of DVT, where a clot must be surgically removed, there may be additional recovery time. Depending on how likely you are to have a blood clot, your doctor might suggest tests, including: 1. For recommendations on treatment after 3 months see the section on long-term anticoagulation for secondary prevention. The decision to stop anticoagulants at 3 months or to treat indefinitely is dominated by the long-term risk of recurrence, and secondarily influenced by the risk of bleeding and by patient preference. Available studies anticoagulated all patients for 3 or 6 months, randomized half to stop and half to continue anticoagulants from that time point, and followed the 2 groups while the extended therapy group was being treated (ie, 1-4 years). DEEP VEIN THROMBOSIS (DVT) PROPHYLAXIS FOLLOWING HIP OR KNEE REPLACEMENT SURGERY: 2.5 mg orally twice a day Duration of therapy:-Hip replacement: 35 days Blood clots are the body’s way of stopping blood loss. The predictive ability of bleeding risk stratification models in very old patients on vitamin K antagonist treatment for venous thromboembolism: results of the prospective collaborative EPICA study. People with an identified cause that will disappear with time, such as bed rest after surgery, may be rid of their blood clots within a few weeks or months. A thrombosis is a blockage of a blood vessel by a blood clot (a thrombus).Embolism occurs when the thrombus dislodges from where it formed and travels in the blood.It then becomes stuck in a narrower blood vessel, elsewhere in the body. If you cut your finger, the blood in the area of injury clumps together, or clots. Clots are formed by blood cells and other factors in the blood. For patients with DVT/PE with stable cardiovascular disease, the ASH guidelines suggest suspending aspirin therapy when initiating anticoagulation. Deep venous thrombosis (DVT) and pulmonary embolism (PE) are the two most important manifestations of venous thromboembolism (VTE), which is … For patients with acute DVT who are not at high risk for post-thrombotic syndrome, the ASH guidelines recommend against the routine use of compression stockings. Your treatment plan will be different depending on which medication you take. Efficacy and safety of novel oral anticoagulants for treatment of acute venous thromboembolism: direct and adjusted indirect meta-analysis of randomised controlled trials. Recurrent venous thromboembolism after deep vein thrombosis: incidence and risk factors. They take into account, with some differences, combinations of sex, d-dimer levels (continuous or binary; on or off anticoagulants), site of initial thrombosis, age when VTE occurred, and signs of PTS (1 rule).53,57,58  Ability to predict the risk of recurrence, and to improve patient outcomes, has yet to be prospectively demonstrated for all 3 rules. Risk of recurrent VTE that justifies strong and weak recommendation for either 3 months or indefinite anticoagulation, Duration of anticoagulation in patients with VTE and cancer, Influence of patient preferences and cost. This review was aimed to provide bedside guidance for clinicians faced with common (and less common) clinical scenarios in DVT treatment. However, there are no validated prediction rules for bleeding during extended anticoagulation for VTE, and the rules that are available have demonstrated limited discriminatory capacity in VTE patients.35,36,59  That, however, does not mean that it is impossible to stratify patients’ risk of bleeding; young (eg, <65 years) healthy patients with good VKA control will have a low risk of major bleeding (≤1% per patient-year), those with less severe factors have an intermediate risk, and elderly patients with severe or multiple factors are at high risk for major bleeding (>4% per patient-year).1,33,59Â. In patients with an unprovoked DVT of the leg (isolated distal or proximal) or PE, we recommend treatment with anticoagulation for at least 3 months over treatment of a shorter duration (Grade 1B), and we recommend treatment with anticoagulation for 3 months over treatment of a longer time-limited period (eg, 6, 12, or 24 months) (Grade 1B). The outpatient bleeding risk index: validation of a tool for predicting bleeding rates in patients treated for deep venous thrombosis and pulmonary embolism. Venous thromboembolism (VTE) is a significant cause of morbidity and mortality in patients with cancer. Whereas the ACCP guidelines divided patients with VTE provoked by a reversible risk factor into 2 categories (provoked by surgery or a nonsurgical trigger), while acknowledging there is a higher risk of recurrence in the later subgroup, we will consider this as a single category. About Deep Vein Thrombosis (DVT)/Blood Clots. A conceptual framework for two phases of anticoagulant treatment of venous thromboembolism. Our recommendations build on those of the American College of Chest Physician’s Evidence-Based Clinical Practice Guidelines for the Treatment of VTE (hereafter referred to as “ACCP guidelines”), and we thank our copanelists for helping to shape our thoughts on this topic.1  Those guidelines also provide recommendations for duration of anticoagulant therapy in patients with upper limb deep vein thrombosis (DVT), superficial vein thrombosis, and thrombosis in unusual sites; topics that will not be addressed here. Anticoagulation for three versus six months in patients with deep vein thrombosis or pulmonary embolism, or both: randomised trial. VTE associated with active cancer, or a second unprovoked VTE, has a high risk of recurrence and is usually treated indefinitely. Men have a higher risk of recurrence than women (1.5- to 2-fold).44,45  Men and women with a positive d-dimer test 1 month after stopping anticoagulants have a higher risk of recurrence than those with a negative test (1.5- to 2.5-fold46 ; difference appears to diminish with longer follow-up47 ), and the influence of these 2 factors on recurrence is at least partly additive.45  However, exactly how sex and d-dimer testing (choice of assay, discriminatory value, single or serial tests) should modify treatment decisions remains unclear.48Â, Factors that are associated with recurrence, but rarely strongly or consistently enough to influence treatment decisions once the primary and secondary estimators have been considered, include: antiphospholipid antibody (relative risk, ∼2)49 ; hereditary thrombophilia (relative risk, ∼1.5)46,50-53 ; Asian ethnicity (relative risk, ∼0.8)54 ; and ultrasound evidence of residual thrombosis in the proximal veins (relative risk, ∼1.5).55  PTS may increase the risk of recurrent VTE,53,56  and recurrent ipsilateral DVT increases the risk of PTS32 ; these considerations may prompt indefinite anticoagulation in patients with severe PTS.48Â. Extended use of dabigatran, warfarin, or placebo in venous thromboembolism. Acute DVT may be treated in an outpatient setting with LMWH. How long is enough? The decision to continue anticoagulation indefinitely after a first unprovoked proximal DVT or PE is strengthened if the patient is male, the index event was PE rather than DVT, and/or d-dimer testing is positive 1 month after stopping anticoagulant therapy. In a direct comparison of treatment duration, anticoagulation for three months or more was superior to a shorter course lasting up to six weeks, showing a reduced risk of recurrence of VTE and DVT with no clear difference in major bleeding and clinically relevant non-major bleeding. Most patients have little difficulty with self-administration especially if they are coached to do their own first injection. Dexamethasone is an inducer of CYP3A4 and the extent of the drug interaction with direct oral anticoagulants is unknown. D‐Dimer testing to select patients with a first unprovoked venous thromboembolism who can stop anticoagulant therapy: a cohort study. No trial has randomized patients with VTE, with or without cancer, to stop or continue anticoagulants and then followed patients indefinitely (eg, for 10 or more years). 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 addition to considering the usual contraindications, we avoid using the new oral anticoagulants in patients who are receiving chemotherapy. Search for other works by this author on: Antithrombotic therapy for VTE disease: Antithrombotic Therapy and Prevention of Thrombosis, 9th ed: American College of Chest Physicians Evidence-Based Clinical Practice Guidelines. It is not known whether the time needed to complete active treatment differs with the type of anticoagulant. The duration of DVT varies from case to case. C.K. an unprovoked clot) or there is an ongoing risk factor that is not removed (e.g. Continued Treating DVT at Home. Kearon C, Akl EA. Mismetti P, Quenet S, Levine M, et al. ment and the choice of anticoagulant drug, dosage, and treatment duration has to reflect the specific situation of the individual DVT patient. Anticoagulation treatment for confirmed DVT or PE 1.3.5 Offer anticoagulation treatment for at least 3 months to people with confirmed proximal DVT or PE. Chronic thromboembolic pulmonary hypertensionÂ, These patients are generally treated with indefinite anticoagulation, whether or not they undergo endarterectomy or if known previous episodes of VTE were provoked by a reversible risk factor.Â, Hereditary thrombophilias are weak risk factors for recurrent VTE, although this is uncertain for antithrombin deficiency. This collection features AFP content on deep venous thrombosis, pulmonary embolism and related issues, including anticoagulation, heparin therapy, and venous thromboembolism. Treatment duration for DVT / PE. Development of a clinical prediction rule for risk stratification of recurrent venous thromboembolism in patients with cancer-associated venous thromboembolism. Anticoagulation period in idiopathic venous thromboembolism. The primary objectives for the treatment of deep venous thrombosis (DVT) are to prevent pulmonary embolism (PE), reduce morbidity, and prevent or minimize the risk of developing the postthrombotic syndrome (PTS). A comparison of three months of anticoagulation with extended anticoagulation for a first episode of idiopathic venous thromboembolism. Compared with VKAs, the new oral anticoagulants are associated with about half the risk of intracranial bleeding, a smaller reduction in all extracranial bleeding, and no reduction or an increase in gastrointestinal bleeding (∼50% higher with dabigatran and rivaroxaban).20,23-25Â, The most important consequence of a recurrent VTE or a major bleed is that it may be fatal. For decades, warfarin ( Coumadin , Jantoven ) has been the go-to drug for treating a DVT. an unprovoked clot) or there is an ongoing risk factor that is not removed (e.g. Kearon C, et al. As the risk of recurrence is expected to be higher in men (∼12% at 1 year and 36% at 5 years) than in women (∼8% at 1 year and 24% at 5 years), and as a new PE is more likely after a PE than after a DVT, being male or having had a PE strengthens the argument for indefinite therapy. Patients with low-risk PE may be safely discharged early from hospital or receive only outpatient treatment with LMWH, followed by vitamin K antagonists, although nonvitamin K-dependent oral anticoagulants may be as effe… We discourage indefinite therapy if there is a convincing reversible risk factor (Table 2). Secondary prevention of venous thromboembolism with the oral direct thrombin inhibitor ximelagatran. This does not apply to patients who have other reasons for hospitalization, who lack support at home, who cannot afford medications, or who present with limb-threatening DVT or at high risk for bleeding. Antiphospholipid antibodies and the risk of recurrence after a first episode of venous thromboembolism: a systematic review. Testing for hereditary thrombophilias in order to guide decisions about treatment duration does not appear to be justified.Â, It is unclear if, independent of other clinical factors, an antiphospholipid antibody justifies indefinite anticoagulant therapy. As previously noted, current evidence suggests that d-dimer levels a month after stopping anticoagulant therapy can help to predict the risk of recurrence in patients with a first unprovoked VTE, with a first-year risk of recurrence of ∼5% for women with a negative d-dimer, 10% for women with a positive d-dimer, 8% for men with a negative d-dimer, and 16% for men with a positive d-dimer. American Society of Hematology 2020 Guidelines for Management of Venous Thromboembolism: Treatment of Deep Vein Thrombosis and Pulmonary Embolism. Ultrasound. VTE provoked by a reversible risk factor, or a first unprovoked isolated distal (calf) deep vein thrombosis (DVT), has a low risk of recurrence and is usually treated for 3 months. The guidelines favor shorter courses of anticoagulation (3-6 months) for acute DVT/PE associated with a transient risk factor. Anticoagulation Management and Venothromboembolism, Congenital Heart Disease and     Pediatric Cardiology, Invasive Cardiovascular Angiography    and Intervention, Pulmonary Hypertension and Venous     Thromboembolism. Treatment is 3 – 6 months if a trigger is identified (e.g. It can detect blockages or blood clots in the deep veins. For DVT and PE, warfarin dose target INR of 2.5 (INR range, 2.0-3.0) for all treatment duration is maintained. If the goal is to reduce the risk of recurrence after a time-limited course of anticoagulation to as low a level as possible, treatment should be stopped once active treatment is completed. The ASH guidelines suggest against the routine use of prognostic scores, D-dimer testing, or venous ultrasound to guide the duration of anticoagulation. The ASH guidelines suggest home treatment over hospitalization for patients with uncomplicated acute DVT. 4 Current guidelines from the American College of Chest Physicians recommend … Prevent the clot from breaking loose and traveling to the lungs. When you return home after DVT treatment, your goals are to get better and prevent another blood clot.You’ll need to: Take medications as directed. We suggest that VTE can be considered provoked if there was a major reversible risk factor within 3 mo, or a minor reversible risk factor within 6 wk (eg, any general anesthesia; soft tissue injury that causes a limp; flight of >8 h; illness that renders the patient bed-bound for a day or chair-bound for 3 d).Â, These patients should be treated for at least 3 mo.
