In both adults and children with diabetes, technologies such as continuous subcutaneous insulin infusion using insulin pumps and continuous glucose monitoring can help improve diabetes control, reduce hypoglycaemia and improve quality of life. Access to these technologies in the UK is very variable. Some technologies are recommended by the National Institute for Health and Care Excellence, while others have not been appraised, and new technologies are emerging all the time. Additionally, different guidelines for adults and children further complicate access to diabetes technology in the transition from paediatric to adult care. Against this background, Diabetes UK and NHS England have brought together a multidisciplinary group of experts, including clinicians and people with diabetes, to develop this consensus guideline, combining the different technologies into a common pathway to aid clinical and policy decision‐making. We created a pathway that supports the incremental addition of technology as monotherapy and then dual therapy in the same way that we incrementally add in therapeutic agents to support people with Type 2 diabetes to achieve their personalized glycaemic targets. The pathway emphasizes the importance of structured education, specialist support and appropriate access to psychological therapies, as essential pillars for optimized use of diabetes‐related technology, and recommends the re‐evaluation of its use when the individual is unable either to use the technology appropriately or to achieve the intended outcomes. This pathway is endorsed by UK‐wide clinical and patient associations and we recommend that providers and commissioners use it to ensure the right individual with diabetes has access to the right technology in a timely way to help achieve better outcomes. 相似文献

Whether severe coagulation factor deficiency can cause adverse pregnancy outcomes or recurrent fetal loss is not definitely known. We report here on five women with severe deficiency of coagulation factors (two factor X, one factor XI, one factor VII and one von Willebrand factor) who presented with history of unexplained fetal loss or with adverse pregnancy outcome. Detailed investigations of thrombophilia showed that four patients were positive for antiphospholipid antibodies, one of whom was also homozygous for the plasminogen-activator inhibitor-1 4G/4G polymorphism, and the fifth patient was deficient for protein C. Despite the concomitant presence of both coagulation factor defect and thrombophilia, fetal loss may be attributed to factor defect that in reality is a red herring, with underlying thrombophilia not being evaluated. 相似文献

Background
Current practice guidelines offer different management recommendations for adults presenting with a sore throat. The key issue is the extent to which the clinical likelihood of a Group A streptococcal infection should affect patient management decisions. To help resolve this issue, we conducted a multi-criteria decision analysis using the Analytic Hierarchy Process. 相似文献9.

The present study describes the clinical and epidemiological features of 74 patients with human immunodeficiency virus (HIV) infection who presented to a referral hospital. Sixty two patients (83.7%) were diagnosed to have acquired immune deficiency syndrome (AIDS). Mean age of the patients was 34.9 +/- 12 years and male to female ratio was 3:1. Majority of patients (80%) were from lower socio-economic class. Multiple unprotected heterosexual contact with commercial sex workers in metropolitan cities of India, mainly Mumbai, was major risk factor in 82.1% male patients while most of the females (66.6%) had acquired infection from HIV positive husbands. Blood transfusion was the risk factor in 9(12.1%) patients. Sixty eight patients were infected with HIV 1, one with HIV 2, and five patients with both HIV 1 and HIV 2. Fever and weight loss were the commonest presenting symptoms. Tuberculosis, oropharyngeal candidiasis, and interstitial pneumonitis were present in 54.8%, 40.3% and 20.9% patients, respectively. Fourteen patients (22.5%) had generalised lymphadenopathy. Herpes zoster, cryptococcal meningitis, and peripheral neuropathy were infrequent. Response to standard antifungal and antitubercular treatment was satisfactory. Kaposi's sarcoma, lymphoma, and CNS toxoplasmosis were not found. The clinical manifestations of AIDS patients are strikingly different from that in the Western countries. It, thus, necessitates setting up of different guidelines for the clinical diagnosis and management of AIDS in India. 相似文献
