Purpose:To evaluate the rate of compliance and the reasons for loss to follow-up in Indian patients with diabetic macular edema (DME), age-related macular degeneration (AMD), and retinal vein occlusion (RVO) being treated with anti-vascular endothelial growth factor (VEGF) therapy.Methods:This was a retrospective single-center study. Patients with DME, AMD, or RVO were eligible if they initiated anti-VEGF therapy between January 2013 and December 2017. Patients'' data were obtained from hospital electronic records, including the number of injections received, visits, details of follow-up, missed appointments, and reasons for loss to follow-up (>365 days).Results:A total of 648 patients were eligible for the study, of which 334 (51.54%) patients were lost to follow-up. Overall, 343 (64.96%) were males and the overall mean (SD) age was 66.40 (7.44) years. A total of 376 (58.0%) patients had a history of diabetes and 364 (56.2%) patients had a history of hypertension. Further, 127 (38.0), 112 (33.5), and 95 (28.4) had DME, AMD, and RVO, respectively and were lost to follow-up. The most commonly reported reason for loss to follow-up was “non-affordability” (n = 120; 41.1%) followed by “no improvement in vision” (n = 83; 28.4%). “No improvement in vision” (42.2%) and “non-affordability” (37.5%) were higher among patients with DME. No association was found in gender- and treatment-wise distribution of reasons for loss to follow-up.Conclusion:The results showed that around half of the patients with DME, AMD, and RVO were lost to follow-up to intravitreal anti-VEGF therapy, and the most common factors were “non-affordability” and “no improvement in vision.” 相似文献

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

38 cases of sarcoma of head and neck region were analysed in a retrospective way in relation to age, anatomic location, histological,
clinical profile, and surgical approaches. Compared to other types of head and neck neoplasms, such as squamous cell carcinoma,
soft tissue sarcomas have low rates of regional metastases. However the biological behaviour of soft tissue sarcoma is more
aggressive specially in paediatric age group. In the present series, CT scan was considered as the primary modality of investigation.
Surgery generally has been recommended as the primary method of treatment for achieving local control, except in those high-grade
tumours arising in sites not amenable to resection. 3-year and 5-year survival rates in this present series 50% and 31.6%
respectively. 相似文献

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
