BACKGROUND: Some relationships are established between diabetes mellitus (DM) and a series of cutaneous disorders. Specific dermatoses are markers for undiagnosed DM. Other disorders represent supervening complications in an already treated DM patient. OBJECTIVE: To review the information about dermocosmetic care products and their appropriate use in the management and prevention of dermatoses related to DM. METHOD: The peer-reviewed literature and empiric findings are covered. Owing to the limited clinical evidence available for the use of dermocosmetics, a review of the routine practices and common therapies in DM-related dermatoses was conducted. RESULTS: Some DM-related dermatoses (acanthosis nigricans, pigmented purpuric dermatosis) are markers of macrovascular complications. The same disorders and some others (xerosis, Dupuytren's disease) have been found to be more frequently associated with microangiopathy. Other skin diseases (alopecia areata, vitiligo) were found to be markers of autoimmunity, particularly in type 1 DM. Unsurprisingly, using dermocosmetics and appropriate skin care has shown objective improvements of some DM-related dermatoses, such effects improve the quality of life. The most common skin manifestations of DM fall along continuum between "dry skin," xerosis, and acquired ichthyosis, occurring predominately on the shins and feet. Dermocosmetic products improve the feeling of well-being for DM patients. [less ▲]

The example of the analysis of a collection of trials in diabetes consisting of a sparsely connected network of 10 treatments is used to make some points about approaches to analysis. In particular various graphical and tabular presentations, both of the network and of the results are provided and the connection to the literature of incomplete blocks is made. It is clear from this example that is inappropriate to treat the main effect of trial as random and the implications of this for analysis are discussed. It is also argued that the generalisation from a classic random-effect meta-analysis to one applied to a network usually involves strong assumptions about the variance components involved. Despite this, it is concluded that such an analysis can be a useful way of exploring a set of trials. [less ▲]

The patient with prediabetes or diabetes has a high or very high risk of cardiovascular diseases.We summarize the recent guidelines jointly published by the European Society of Cardiology and the European Society for the Study of Diabetes. In this first article, we focus mainly on the preventive approaches of cardiovascular diseases in patients with prediabetes or (type 1 or type 2) diabetes. The crucial importance of a global multifactorial strategy is emphasized and the target levels of various risk factors are updated. The management of these cardiovascular complications in presence of diabetes will be considered in a second article. [less ▲]

The 11 beta-hydroxysteroid dehydrogenase type 1 (11βHSD1) enzyme promotes the local conversion from cortisone to cortisol, especially in the adipose tissue and the liver. It may play a role in the pathophysiology of abdominal obesity and the metabolic syndrome, both showing some similarities with the Cushing syndrome. Synthetic selective inhibitors of 11βHSD1 are currently in development with encouraging preliminary results that remain, however, to be further improved. Selective inhibitors of 11βHSD1 may represent an innovative approach in the pharmacological management of obesity, metabolic syndrome and type 2 diabetes. [less ▲]

Numerous epidemiological cohort and case-control studies showed that type 2 diabetes is a risk factor for cancer and that metformin therapy is associated with a significant reduction in the incidence of cancer and cancer-related death when compared to other glucose-lowering agents. Such beneficial effect is observed whatever the type of cancer, but seems to be more prominent in case of gastrointestinal and breast cancers. In general, the protective effect was more evident in observational cohort studies (however, more exposed to bias due to confounding factors) than in case-control studies. However, the results of the rather rare controlled clinical trials available are not conclusive, but none of them was performed with the objective to specifically assess cancer risk. Several meta-analyses recently confirmed that metformin therapy reduces the incidence of cancers (including colorectal cancer, hepatocarcinoma, breast cancer) and cancer-related mortality. Metformin may exert its anti-cancer activity by a direct effect (insulin) and an indirect effect (AMPK and mTOR). Considering all promising clinical information in patients with type 2 diabetes, further clinical trials are currently ongoing with the aim of assessing the role of metformin in oncology, especially as adjuvant in breast cancer therapy.

AIMS: To establish the association between albuminuria and cardiovascular risk factors as well as micro- and macrovascular complications in type 1 and insulin-treated type 2 diabetes, both in the presence and in the absence of reduced estimated glomerular filtration rate (eGFR). METHODS: Cross-sectional study including 7640 insulin-treated diabetic patients (33% type 1) treated in specialist diabetes centers. Albuminuria was defined as >/=30mg/g, 20mg/L, 20mug/min or 30mg/24h. Reduced eGFR was defined as <60mL/min/1.73m2 (CKD-EPI equations). RESULTS: Albuminuria, reduced eGFR or a combination was more prevalent in type 2 (21.5%, 15.9% and 16.5%) than in type 1 diabetes (16.1%, 4.7% and 4.0%, all P<0.001 vs. type 2). Albuminuria was associated with poorer control of blood pressure, blood lipids and glycemia as well as higher prevalence of retinopathy and macrovascular disease, regardless of preserved/reduced eGFR or diabetes type. Reduced eGFR was associated with higher prevalence of micro- and macrovascular complications especially in type 2 diabetes. Combined presence of albuminuria and reduced eGFR was associated with the worst cardiovascular outcomes. CONCLUSIONS: Albuminuria and impaired renal function are prevalent in type 1 and insulin-treated type 2 diabetes. Albuminuria, but also normoalbuminuric renal impairment, is associated with micro- and macrovascular complications. [less ▲]

Metformin is unanimously considered as the first-line glucose-lowering agent in type 2 diabetes. Theoretically, however, it cannot be prescribed in a large proportion of patients because of the presence of numerous contraindications corresponding to situations that may increase the risk of lactic acidosis. Recent data suggest that type 2 diabetes patients who are considered as being "at risk" because of the presence of cardiac disease still take benefit from metformin therapy, with a reduction of morbidity and mortality compared with other glucose-lowering agents. The present review analyzes the benefit-risk balance of metformin therapy in special populations, namely patients with stable coronary artery disease, acute coronary syndrome or myocardial infarction, or congestive heart failure.

Workaholism belongs to the behavioural addictions, also called ((without substances)) addictions, and is rather common in our society. The differential diagnosis must distinguish a hard worker, who has pleasure in his/her job, still profits from leisure time and maintains an excellent quality of life, from a true workaholic, who is prisoner of this compulsive behaviour that has negative consequences on his mental and physical health, his social and familial relationships and finally, his work performance itself. We describe here the various typologies of this mental disorder, its mode of evolution, its diagnostic approach, its multiple negative consequences for both patient and family as well as the main principles of management based on cognitive-behavioural therapy of this disorder that may be considered as a true addiction.

Pharmacological treatment of type 2 diabetes has been enriched during recent years, with the launch of incretin therapies targeting glucagon-like peptide-1 (GLP-1). Such medications comprise either GLP-1 receptor agonists, with short (one or two daily injections: exenatide, liraglutide, lixisenatide) or long duration (one injection once weekly: extended-released exenatide, albiglutide, dulaglutide, taspoglutide); or oral compounds inhibiting dipeptidyl peptidase-4 (DPP-4), the enzyme that inactives GLP-1, also called gliptins (sitagliptin, vildagliptin, saxagliptin, linagliptin, alogliptin). Although both pharmacological approaches target GLP-1, important differences exist concerning the mode of administration (subcutaneous injection versus oral ingestion), the efficacy (better with GLP-1 agonists), the effects on body weight and systolic blood pressure (diminution with agonists versus neutrality with gliptins), the tolerance profile (nausea and possibly vomiting with agonists) and the cost (higher with GLP-1 receptor agonists). Both agents may exert favourable cardiovascular effects. Gliptins may represent a valuable alternative to a sulfonylurea or a glitazone after failure of monotherapy with metformin while GLP-1 receptor agonists may be considered as a good alternative to insulin (especially in obese patients) after failure of a dual oral therapy. However, this scheme is probably too restrictive and modalities of using incretins are numerous, in almost all stages of type 2 diabetes. Physicians may guide the pharmacological choice based on clinical characteristics, therapeutic goals and patient's preference. [less ▲]

With the better management of cardiovascular risk factors, cancer plays an increasing role in the causes of death among patients with type 2 diabetes. Numerous epidemiological cohort and case-control studies showed that type 2 diabetes is a risk factor for cancer and that metformin therapy is associated with a significant reduction in the incidence of cancer and cancer-related death when compared to other glucose-lowering agents (sulfonylureas, insulin). Such beneficial effect is observed almost whatever the type of cancer, but seems to be more prominent in case of gastrointestinal and breast cancers. Several studies showed a significant relationship between the amplitude of the protection against cancer, on the one hand, and the daily dose of metformin and the duration of exposure, on the other hand. In general, the protective effect was more evident in observational cohort studies (however, more exposed to bias due to confounding factors) than in case-control studies. Several meta-analyses recently confirmed that metformin therapy reduces the incidence of cancers and cancer-related mortality. However, the results of the rather rare controlled clinical trials available are not conclusive, but none of them was performed with the objective to specifically assess cancer risk. Considering all promising clinical information in patients with type 2 diabetes, further clinical trials are currently ongoing with the aim of assessing the role of metformin in oncology, independently of the presence of diabetes.

Obesity is increasingly prevalent in our society and medical consultations for evaluation and management of weight excess are frequent. Before considering a therapeutic strategy, a careful initial clinical assessment is mandatory. The diagnostic approach of an obese person should be similar as for any other chronic pathology. The objectives of the present clinical description are to report the main steps of an exhaustive anamnesis, the signs to be more specifically detected at the clinical examination and the other useful investigations to be programmed at first glance in a person who is visiting his/her medical doctor because of obesity. Based upon the data collected during this careful evaluation, therapeutic modalities may be defined, ideally in the frame of a multidisciplinary approach. [less ▲]
