Background: Clinicians confront numerous practical issues in optimizing the use of anticoagulants to treat venous thromboembolism (VTE). Objective: These evidence-based guidelines of the American Society of Hematology (ASH) are intended to support patients, clinicians and other health care professionals in their decisions about the use of anticoagulants in the management of VTE. These guidelines assume the choice of anticoagulant has already been made. Methods: ASH formed a multidisciplinary guideline panel balanced to minimize potential bias from conflicts of interest. The McMaster University GRADE Centre supported the guideline development process, including updating or performing systematic evidence reviews. The panel prioritized clinical questions and outcomes according to their importance for clinicians and patients. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach was used to assess evidence and make recommendations, which were subject to public comment. Results: The panel agreed on 25 recommendations and 2 good practice statements to optimize management of patients receiving anticoagulants. Conclusions: Strong recommendations included using patient self-management of international normalized ratio (INR) with home point-of-care INR monitoring for vitamin K antagonist therapy and against using periprocedural low-molecular-weight heparin (LMWH) bridging therapy. Conditional recommendations included basing treatment dosing of LMWH on actual body weight, not using anti–factor Xa monitoring to guide LMWH dosing, using specialized anticoagulation management services, and resuming anticoagulation after episodes of life-threatening bleeding.

Phantom breast syndrome (PBS) following mastectomy has already been reported by other authors. The temporal course, character and extent of these phenomena, however, have not yet been elucidated. In a prospective study, we investigated the incidence, clinical picture and the temporal course of PBS. One hundred and twenty women who, during a 1 year period, embarked consecutively on post-operative control or treatment at the department, were interviewed by a standard questionnaire 3 weeks after the operation. One year later 110 patients were interviewed again. The median age at the first interview was 54 years (Q1 = 45 years; Q3 = 62 years). The incidence of PBS was 25.8% at the first interview and 24.5% at the second. The incidence of phantom pain and non-painful phantom sensations was 13.3% and 15.0%, respectively, 3 weeks after mastectomy and 12.7% and 11.8%, respectively after 1 year. We found significant relationships between pre-operative pain and PBS, but no significant relation between age and the occurrence of PBS. Neither post-operative sequelae nor cancer treatment including radiotherapy seemed to affect the occurrence of PBS. Exteroceptive-like pain emerged as the most predominant type of pain from both interviews. At the time of the first interview, 35.0% of the patients experienced cicatrix pain which was clearly distinguishable from phantom pain; after 1 year, 22.7% of the patients had persistent cicatrix pain. The present incidence of PBS is close to the incidence reported by others. Persistent phantom pain may, however, be more common than usually expected. Also persistence of cicatrix pain seems to be more common than generally expected.

Purpose: Diabetic retinopathy (DR) is among the leading causes of visual loss in the working-age population. It is generally accepted that screening of DR is costeffective and can detect DR before it becomes sight-threatening to allow timely treatment. Methods: A group of retinal specialists was formed by the Danish Ophthalmological Society with the aim to formulate contemporary evidence-based guidelines for screening of DR in order to implement these in the Danish screening system. Results: We hereby present evidence for DR-screening regarding (1) classification of DR, (2) examination techniques, (3) screening intervals and (4) automated screening. It is our recommendation that the International Clinical Retinopathy Disease Severity Scale should be used to classify DR. As a minimum, mydriatic two-field disc-and macular-centred images are required. In the case of suspected clinically significant diabetic macular oedema, supplementary optical coherence tomography can increase the diagnostic accuracy. There is solid evidence to support a flexible, individualized screening regimen. In particular, it is possible to prolong screening intervals to 24-48 months for patients with no or mild nonproliferative diabetic retinopathy (NPDR), but it is also possible to use extended intervals of 12-24 months for patients with moderate NPDR given that these are well-regulated regarding glycaemic control (HbA1c ≤ 53 mmol/mol) and blood pressure (≤130/80 mmHg). Automated screening of DR is encouraging but is not ready for implementation at present. Conclusion: Danish evidenced-based guidelines for screening of DR support high-quality imaging and allow flexible, individualized screening intervals with a potential for extension to patients with low risk of DR progression.

Our results demonstrate an effect of 3 months of daily endurance exercise on biomarkers of the haemostatic balance in the direction of reduced cardiovascular risk, independent of exercise dose.

Intraocular pressure (IOP) was measured before and 6, 24, 48 and 72 h after extracapsular cataract extraction with implantation of a posterior chambers lens in 3 groups of patients. Group I (30 patients): Sodium hyaluronate (Healon) was used during anterior capsulotomy and lens implantation and was aspirated at the end of surgery. Group II (22 patients): Healon as in group I + 500 mg acetazolamide at the end of surgery. Group III (17 patients): BSS and/or air was used instead of Healon during surgery. In all groups statistically significant rises in IOP after 6 h were followed by significant falls in the remaining post-operative period. The rise and subsequent fall in IOP was significantly greater in group I than in group III. Acetazolamide in group II did not prevent excessive rises in IOP. Aspiration probably shortens the period of Healon-induced hypertension. We recommend a meticulous aspiration of Healon at the end of surgery.
