Improving glucose management: ten steps to get more patients with type 2 diabetes to glycaemic goal.

Despite increasingly stringent clinical practice guidelines for glycaemic control, the implementation of recommendations has been disappointing, with over 60% of patients not reaching recommended glycaemic goals. As a result, current management of glycaemia falls significantly short of accepted treatment goals. The Global Partnership for Effective Diabetes Management has identified a number of major barriers that can prevent individuals from achieving their glycaemic targets. This article proposes 10 key practical recommendations to aid healthcare providers in overcoming these barriers and to enable a greater proportion of patients to achieve glycaemic goals. These include advice on targeting the underlying pathophysiology of type 2 diabetes, treating early and effectively with combination therapies, adopting a holistic, multidisciplinary approach and improving patient understanding of type 2 diabetes. Implementation of these recommendations should reduce the risk of diabetes-related complications, improve patient quality of life and impact more effectively on the increasing healthcare cost related to diabetes.

Sepsis in cirrhosis: report on the 7th meeting of the International Ascites Club.

Sepsis is a systemic inflammatory response to the presence of infection, mediated via the production of many cytokines, including tumour necrosis factor (TNF-), interleukin (IL)-6, and IL-1, which cause changes in the circulation and in the coagulation cascade. There is stagnation of blood flow and poor oxygenation, subclinical coagulopathy with elevated D-dimers, and increased production of superoxide from nitric oxide synthase. All of these changes favour endothelial apoptosis and necrosis as well as increased oxidant stress. Reduced levels of activated protein C, which is normally anti-inflammatory and antiapoptotic, can lead to further tissue injury. Cirrhotic patients are particularly susceptible to bacterial infections because of increased bacterial translocation, possibly related to liver dysfunction and reduced reticuloendothelial function. Sepsis ensues when there is overactivation of pathways involved in the development of the sepsis syndrome, associated with complications such as renal failure, encephalopathy, gastrointestinal bleed, and shock with decreased survival. Thus the treating physician needs to be vigilant in diagnosing and treating bacterial infections in cirrhosis early, in order to prevent the development and downward spiral of the sepsis syndrome. Recent advances in management strategies of infections in cirrhosis have helped to improve the prognosis of these patients. These include the use of prophylactic antibiotics in patients with gastrointestinal bleed to prevent infection and the use of albumin in patients with spontaneous bacterial peritonitis to reduce the incidence of renal impairment. The use of antibiotics has to be judicious, as their indiscriminate use can lead to antibiotic resistance with potentially disastrous consequences.

Adult Asthma Consensus Guidelines update 2003.

BACKGROUND: Several sets of Canadian guidelines for the diagnosis and management of asthma have been published over the past 15 years. Since the last revision of the 1999 Canadian Asthma Consensus Report, important new studies have highlighted the need to incorporate new information into the asthma guidelines. OBJECTIVES: To review the literature on adult asthma management published between January 2000 and June 2003; to evaluate the influence of the new evidence on the recommendations made in the 1999 Canadian Asthma Consensus Guidelines and its 2001 update; and to report new recommendations on adult asthma management. METHODS: Three specific topics for which new evidence affected the previous recommendations were selected for review: initial treatment of asthma, add-on therapies in the treatment of asthma and asthma education. The resultant reviews were discussed in June 2003 at a meeting under the auspices of the Canadian Thoracic Society, and recommendations for adult asthma management were reviewed. RESULTS: The present report emphasises the importance of the early introduction of inhaled corticosteroids in symptomatic patients with mild asthma; stresses the benefit of adding additional therapy, preferably long-acting beta2-agonists, to patients incompletely controlled on low doses of inhaled corticosteroids; and documents the essential role of asthma education. CONCLUSION: The present report generally supports many of the previous recommendations published in the 1999 Canadian Asthma Consensus Report and provides higher levels of evidence for a number of those recommendations.

Prostate pathology of genetically engineered mice: definitions and classification. The consensus report from the Bar Harbor meeting of the Mouse Models of Human Cancer Consortium Prostate Pathology Committee.

The Pathological Classification of Prostate Lesions in Genetically Engineered Mice (GEM) is the result of a directive from the National Cancer Institute Mouse Models of Human Cancer Consortium Prostate Steering Committee to provide a hierarchical taxonomy of disorders of the mouse prostate to facilitate classification of existing and newly created mouse models and the translation to human prostate pathology. The proposed Bar Harbor Classification system is the culmination of three meetings and workshops attended by various members of the Prostate Pathology Committee of the Mouse Models of Human Cancer Consortium. A 2-day Pathology Workshop was held at The Jackson Laboratory in Bar Harbor, Maine, in October 2001, in which study sets of 93 slides from 22 GEM models were provided to individual panel members. The comparison of mouse and human prostate anatomy and disease demonstrates significant differences and considerable similarities that bear on the interpretation of the origin and natural history of their diseases. The recommended classification of mouse prostate pathology is hierarchical, and includes developmental, inflammatory, benign proliferative, and neoplastic disorders. Among the neoplastic disorders, preinvasive, microinvasive, and poorly differentiated neoplasms received the most attention. Specific criteria were recommended and will be discussed. Transitions between neoplastic states were of particular concern. Preinvasive neoplasias of the mouse prostate were recognized as focal, atypical, and progressive lesions. These lesions were designated as mouse prostatic intraepithelial neoplasia (mPIN). Some atypical lesions were identified in mouse models without evidence of progression to malignancy. The panel recommended that mPIN lesions not be given histological grades, but that mPIN be further classified as to the absence or presence of documented associated progression to invasive carcinoma. Criteria for recognizing microinvasion, for classification of invasive gland-forming adenocarcinomas, and for characterizing poorly differentiated tumors, including neuroendocrine carcinomas, were developed and are discussed. The uniform application of defined terminology is essential for correlating results between different laboratories and models. It is recommended that investigators use the Bar Harbor Classification system when characterizing new GEM models or when conducting experimental interventions that may alter the phenotype or natural history of lesion progression in existing models.

A surgical and pathological based classification of resective treatment of pancreatic cancer. Summary of an international workshop on surgical procedures in pancreatic cancer.

BACKGROUND: The extent of pancreatic resection and lymphadenectomy, both for Kausch-Whipple pancreatoduodenectomy and for left pancreatectomy, is variable between surgeons, according to their training. METHODS: On May 30, 1998, a consensus conference on the surgical treatment of pancreatic cancer took place in Castelfranco Veneto, Italy. A group of 29 European surgeons and pathologists, recognized as international experts, analyzed the surgical and pathological procedures used in European countries to resect pancreatic cancer and examine the specimen. RESULTS: A general agreement was reached on the definitions of standard , 'radical and 'extended radical Kausch-Whipple pancreatoduodenectomy for carcinoma of the head of the pancreas, and standard and 'radical left pancreatectomy for carcinoma of the body and tail of the pancreas. Segmental venous resection, as well as adjacent organ resection, can be performed at the time of standard, radical or extended radical pancreatoduodenectomy or left pancreatectomy if required. The pylorus-preserving procedure is contraindicated only for carcinomas of the anteriorsuperior part of the head of the pancreas. Guidelines for a standardized pathological examination of the resected specimen were produced. CONCLUSION: Adoption of the recommended terminology will improve outcome comparisons between institutions performing the different procedures. Moreover, standardization of operations, terminology and pathological reporting is essential for prospective randomized trials comparing different operations either alone or within the context of adjuvant therapy studies.

Raising high-density lipoprotein cholesterol with reduction of cardiovascular risk: the role of nicotinic acid--a position paper developed by the European Consensus Panel on HDL-C.

Reduction of low-density lipoprotein cholesterol (LDL-C) is presently the primary focus of lipid-lowering therapy for prevention and treatment of coronary heart disease (CHD). However, the high level of residual risk among statin-treated patients in recent coronary prevention studies indicates the need for modification of other major components of the atherogenic lipid profile. There is overwhelming evidence that a low plasma level of high-density lipoprotein cholesterol (HDL-C) is an important independent risk factor for CHD. Moreover, a substantial proportion of patients with or at risk of developing premature CHD typically exhibit distinct lipid abnormalities, including low HDL-C levels. Thus, therapeutic intervention aimed at raising HDL-C, within the context of reducing global cardiovascular risk, would benefit such patients, a viewpoint increasingly adopted by international treatment guidelines. Therapeutic options for patients with low HDL-C include treatment with statins, fibrates and nicotinic acid, either as monotherapy or in combination. Of these options, nicotinic acid is not only the most potent agent for raising HDL-C but is also effective in reducing key atherogenic lipid components including triglyceride-rich lipoproteins (mainly very low-density lipoproteins [VLDL] and VLDL remnants), LDL-C, and lipoprotein(a). The principal features of the atherogenic lipid profile in type 2 diabetes and the metabolic syndrome make them logical targets for nicotinic acid therapy, either alone or in combination with a statin. The lack of comprehensive European data on the prevalence of low HDL-C levels highlights a critical need for education on the importance of raising HDL-C in CHD prevention and treatment. The development of a reliable and accurate assay for HDL-C, as well as clarification of criteria for low and optimal levels of HDL-C in both men and women, constitute critical factors in the reliable identification and treatment of patients at elevated risk of CHD due to low HDL-C. Based on the available evidence, the European Consensus Panel recommends that the minimum target for HDL-C should be 40 mg/dL (1.03 mmol/L) in patients with CHD or with a high level of risk for CHD, including patients at high global risk with type 2 diabetes or the metabolic syndrome.
