A Type 1 diabetes technology pathway: consensus statement for the use of technology in Type 1 diabetes

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.     

105Changes in Nitric Oxide Levels After Deep Dermal injury in the Female,Red Duroc Pig (FRDP)

Introduction : Hypertrophic scar is a devastating sequel to burns and other tangential skin injuries. It follows deep dermal injuries and does not occur after superficial injuries. Nitric oxide (NO) plays many important roles in wound healing from inflammation to scar remodeling. Studies have shown that expression of nitric oxide synthase and nitric oxide production are decreased in human hypertrophic scar. However little is known about NO involvement in the early stages of hypertrophic scarring, because of the lack of an animal model. It was recently reported that the female red Duroc pig (FRDP) makes thick scar, which is similar to human hypertrophic scar. We hypothesized that NO production in wounds on the female, red Duroc pig is similar to that of human hypertrophic scar and that NO involvement in deep wounds is different from that in superficial wounds. Methods : Superficial (0.015” to 0.030”) and deep (0.045” to 0.060”) wounds were created on the backs of four FRDPs. Biopsies were collected at weeks 1.5, 4, 8 and 21 post wounding including samples of uninjured skin. Nitric oxide levels were measured with the Griess reaction assay and normalized with tissue protein level. Results : Superficial wounds healed with an invisible scar whereas the deep wounds healed with scar resembling mild hypertrophic scar. The thickness of the scars from the deep wounds was significantly greater than uninjured skin and healed superficial wounds (p < 0.01). NO levels were increased at 1.5 weeks in deep wounds compared to superficial wounds and uninjured skin (p < 0.05). At 8 weeks, NO levels in deep wounds had returned to the level of uninjured tissue and superficial wounds. By 21 weeks, NO levels had decreased significantly when compared to superficial wounds (p < 0.01). There were no differences in NO levels between uninjured skin and superficial wounds at any time point (p > 0.05). Conclusions : NO production is similar in late, deep wounds on the female, red Duroc pig to that reported in the literature for human hypertrophic scar further validating this animal model. NO production is quite different after deep wounds as compared to superficial wounds in the FRDP. Early elevation in nitric oxide production might account for excessive inflammation in deep wounds that become thick scars in the FRDP. Nitric oxide regulators and effects at early stages of scar formation should be elucidated further and the FRDP appears to be a useful model.     

Clinical profile of AIDS: a study at a referral hospital

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.
