Impact of residual pulmonary obstruction on the long-term outcome of patients with pulmonary embolism.

The impact of residual pulmonary obstruction on the outcome of patients with pulmonary embolism is uncertain.We recruited 647 consecutive symptomatic patients with a first episode of pulmonary embolism, with or without concomitant deep venous thrombosis. They received conventional anticoagulation, were assessed for residual pulmonary obstruction through perfusion lung scanning after 6 months and then were followed up for up to 3 years. Recurrent venous thromboembolism and chronic thromboembolic pulmonary hypertension were assessed according to widely accepted criteria.Residual pulmonary obstruction was detected in 324 patients (50.1%, 95% CI 46.2-54.0%). Patients with residual pulmonary obstruction were more likely to be older and to have an unprovoked episode. After a 3-year follow-up, recurrent venous thromboembolism and/or chronic thromboembolic pulmonary hypertension developed in 34 out of the 324 patients (10.5%) with residual pulmonary obstruction and in 15 out of the 323 patients (4.6%) without residual pulmonary obstruction, leading to an adjusted hazard ratio of 2.26 (95% CI 1.23-4.16).Residual pulmonary obstruction, as detected with perfusion lung scanning at 6 months after a first episode of pulmonary embolism, is an independent predictor of recurrent venous thromboembolism and/or chronic thromboembolic pulmonary hypertension.

Trialogue Plus: Management of cardiovascular risk in hyperglycaemic/diabetic patients at hospital discharge.

Diabetes mellitus and hyperglycaemia are both independent risk factors (RF) for cardiovascular (CV) events and increased general and CV mortality. Type 2 diabetes, which is often associated with obesity, hypertension and dyslipidaemia, is accompanied by an up to fourfold increase in the incidence of acute coronary heart disease compared to normoglycaemia, even when other CV RF are equal. In the diabetic population, acute CV events are more likely to have associated cardiac complications, such as heart failure, and CV mortality is increased by twofold­fourfold. Several patients, hospitalised in medical, cardiology and intensive care departments, have undiagnosed diabetes mellitus or elevated glucose levels at the time of admission. These conditions require intensive care in the acute phase and dedicated follow-up at discharge. The Trialogue Plus project was created with the goal of providing good clinical practice guidelines and recommendations for the management of CV risk in patients with diabetes/hyperglycaemia at discharge from hospital. The aim is developing a document that defines timing, diagnostics, targets and therapeutic strategy for the management of CV risk, both in primary and in secondary prevention of patients with diabetes/hyperglycaemia who have experienced an event, involving the Diabetologist, Cardiologist, Internist, GP and area Specialists. This document concerns the implementation of existing guidelines and consensus statements, and as such, the recommendations have not been classified on the basis of scientific evidence and strength.

Trialogue : managing hyperglycaemia in internal medicine: instructions for use.

Hyperglycaemic patients admitted to hospital have worse clinical outcomes with higher operational costs than normoglycaemic patients. Identifying, defining and treating hyperglycaemia promptly and appropriately is essential during hospitalisation; adequate 'continuity of care' must be assured after discharge. This requires a multidisciplinary clinical collaboration between the internist and the diabetes team, which plays a central role in the treatment course and should be involved soon after patient admission to the hospital. This document aims to establish guidelines and recommendations for good clinical practice in managing hyperglycaemic internal medicine patients, with or without previous diagnosis of diabetes. The Associazione Medici Diabetologi (AMD), Federazione delle Associazioni dei Dirigenti Ospedalieri Internisti (FADOI) and Società Italiana di Diabetologia (SID) have decided to publish a document useful for internists in the management of hospitalised patients with hyperglycaemia. The Trialogue project, coordinated by a Board of Scientific Experts from the three scientific societies, was initiated for this purpose. A questionnaire consisting of 16 multiple choice questions on the management of hyperglycaemia in hospital was answered by 660 physicians from over 250 Internal Medicine units distributed throughout Italy. Analysis of responses has yielded an overview of routine clinical practice and provided a wealth of ideas to better identify critical points in the treatment of hospitalised patients with hyperglycaemia. These recommendations were developed with the aim of providing mutually agreed practical guidance (instructions for use) that can be readily applied by healthcare professionals in routine clinical practice.

Lipid accumulation in overweight type 2 diabetic subjects: relationships with insulin sensitivity and adipokines.

Adipokines are known to play a fundamental role in the etiology of obesity, that is, in the impaired balance between increased feeding and decreased energy expenditure. While the adipokine-induced changes of insulin resistance in obese diabetic and nondiabetic subjects are well known, the possible role of fat source in modulating insulin sensitivity (IS) remains controversial. The aim of our study was to explore in overweight type 2 diabetic patients (T2DM) with metabolic syndrome IS in different energy storage conditions (basal and dynamic) for relating it to leptin and adiponectin. Sixteen T2DM (5/11 F/M; 59 ± 2 years; 29.5 ± 1.1 kg/m(2)) and 16 control (CNT 5/11; 54 ± 2; 29.1 ± 1.0) underwent an oral glucose tolerance test. Fasting IS was measured by QUICKI, while the dynamic one with OGIS. The insulinogenic index (IGI) described beta cell function. Also, the lipid accumulation product parameter (LAP) was assessed. LAP accounts for visceral abdominal fat and triglycerides, and it is known to be related to IS. Possible interrelationships between LAP and adipokines were explored. In T2DM and CNT, adiponectin (7.4 ± 0.5 vs. 7.8 ± 0.9 µg/mL), leptin (13.3 ± 3.0 vs. 12.4 ± 2.6 ng/mL), and QUICKI (0.33 ± 0.01 vs. 0.33 ± 0.01) were not different (P > 0.40), at variance with OGIS (317 ± 11 vs. 406 ± 13 mL/min/m(2); P = 0.006) and IGI (0.029 ± 0.005 vs. 0.185 ± 0.029 × 10(3) pmolI/mmolG; P = 0.00001). LAP was 85 ± 15 cm × mg/dL in T2DM and 74 ± 10 in CNT (P > 0.1), correlated with OGIS in all subjects (R = -0.42, P = 0.02) and QUICKI (R = -0.56, P = 0.025) in T2DM. Leptin correlated with QUICKI (R = -0.45, P = 0.009), and adiponectin correlated with OGIS (R = 0.43, P = 0.015). In overweight T2DM, insulin sensitivity in basal condition appears to be multifaceted with respect to the dynamic one, because it should be more fat-related. Insulin sensitivity appears to be incompletely described by functions of fasting glucose and insulin values alone and the use of other indices, such as LAP could be suggested.
