Brandon S J Davies
Three members of the angiopoietin-like (ANGPTL) family of proteins, ANGPTL3, ANGPTL4 and ANGPTL8, are known regulators of plasma triacylglycerol levels. Recently, these three proteins have garnered considerable interest as potential targets for therapeutically reducing plasma triacylglycerol levels and improving cardiovascular outcomes. In this issue of Diabetologia, Janssen et al ( https://doi.org/10.1007/s00125-018-4583-5 ) and Vatner et al ( https://doi.org/10.1007/s00125-018-4579-1 ) show that reducing levels of ANGPTL4 and ANGPTL8, respectively, could have the added benefit of improving glucose tolerance...

Direct in vivo assessment of pancreatic islet-cells for the study of the pathophysiology of diabetes in humans is hampered by anatomical and technological hurdles. To date, most of the information that has been generated is derived from histological studies performed on pancreatic tissue from autopsy, surgery, in vivo biopsy or organ donation. Each approach has its advantages and disadvantages (as summarised in this commentary); however, in this edition of Diabetologia, Kusmartseva et al ( https://doi.org/10...

Post-translational modification of proteins contributes to the control of cell function and survival. The balance of these in insulin-producing pancreatic beta cells is important for the maintenance of glucose homeostasis. Protection from the damaging effects of reactive oxygen species is required for beta cell survival, but if this happens at the expense of insulin secretory function then the ability of islets to respond to changing metabolic conditions may be compromised.

In a paper in this issue of Diabetologia (DOI: https://doi.org/10.1007/s00125-017-4417-x ), Vouillarmet and colleagues have explored the use of single-photon emission computed tomography (SPECT)/computed tomography (CT) to define remission during non-surgical management of osteomyelitis of the foot. Their experience in a non-controlled observational study of 45 individuals was that a negative white blood cell-SPECT/CT scan is a reliable marker of remission, while a positive scan at the end of antibiotic treatment may be relatively useful in the prediction of future short- to medium-term relapse...

In the Trial Comparing Cardiovascular Safety of Insulin Degludec vs Insulin Glargine in Patients with Type 2 Diabetes at High Risk of Cardiovascular Events (DEVOTE), insulin degludec was non-inferior to insulin glargine in terms of cardiovascular events and mortality. However, there were lower rates of severe hypoglycaemia with insulin degludec. DEVOTE investigators now extend these findings by presenting the results of two observational epidemiological analyses based on trial data. In the first of these analyses (DEVOTE 2), Zinman et al (Diabetologia DOI: 10...

BACKGROUND: Bibliometric analysis is an approach to evaluate the circumstances and trends in specific research field over time and to provide inspiration in future research and policy. Researches have a tremendous increase focus on the role of the microbiota in the development of diabetes in recent years; however, there is no published literature conducting a bibliometric analysis to explore the tendency. The aim of this study was to provide a detailed evaluation of the hundred most cited articles in microbiota of diabetes research...

RCTs of whether screening asymptomatic individuals for undiagnosed diabetes results in reduced mortality or has other benefits have been suggestive, but inconclusive. In this issue of Diabetologia, two additional controlled studies (DOIs: 10.1007/s00125-017-4323-2 and 10.1007/s00125-017-4299-y ) that investigated whether screening for type 2 diabetes in asymptomatic individuals is associated with a reduction in mortality are presented. Treating diabetes early, and identifying and treating impaired glucose tolerance, are of benefit, and economic modelling indicates such screening is cost-effective...

Large-scale, centrally-coordinated screening for undiagnosed type 2 diabetes is an attractive option to reduce the mortality and morbidity resulting from inadequately controlled diabetes. However, there is limited research examining the direct consequences of such screening programmes on outcomes such as cardiovascular disease and death. Two papers published in this edition of Diabetologia (DOIs: 10.1007/s00125-017-4323-2 and 10.1007/s00125-017-4299-y ) examine data from one of the very few trials conducted in this area...

About 20 years ago an American study suggested that daily subcutaneous injections of a metabolically inactive insulin analogue with a single amino acid substitution (aspartic acid instead of phenylalanine) at position 25 of the B chain was as effective as intact insulin in preventing autoimmune diabetes in NOD mice. In this issue of Diabetologia Grönholm et al (DOI: 10.1007/s00125-017-4276-5 ) report that parenteral administration of the same insulin analogue has no preventive effect whatsoever on the development of diabetes in NOD mice; in fact, high doses of the metabolically inactive insulin accelerated disease development...

The role of B lymphocytes in the pathogenesis of type 1 diabetes in humans is not entirely evident. These cells are presumed to be important, but this assumption is largely based on animal models of autoimmune diabetes, where compelling evidence for the contribution of both B lymphocytes and insulin-specific autoantibodies to this disease is in place. For humans, this is much less the case; the exact way in which B lymphocytes and/or autoantibodies may contribute to type 1 diabetes is not yet known but the possibilities include a pathogenic function ('fire'), or they may represent a surrogate of loss of immune tolerance to beta cells ('smoke') or, indeed, they could be a marker of an attempt at immune regulation ('ice water')...

Skeletal fragility often accompanies diabetes and does not appear to correlate with low bone mass or trauma severity in individuals with diabetes. Instead (and in contrast to those with osteoporotic bone disease), bone remodelling and bone turnover are compromised in both type 1 and type 2 diabetes, contributing to defective bone material quality.

MODY is an early-onset monogenic form of diabetes. Correctly identifying MODY is of considerable importance as diagnosing the specific genetic subtype can inform the optimal treatment, with many patients being able to discontinue unnecessary insulin treatment. Diagnostic molecular genetic testing to confirm MODY is expensive, so screening strategies are required to identify the most appropriate patients for testing. In this issue of Diabetologia, Johansson and colleagues (DOI 10.1007/s00125-016-4167-1 ) describe a nationwide systematic screening approach to identify individuals with MODY in the paediatric age range...

While regular structured exercise is a well-established (though arguably under-utilised) cornerstone in the prevention and management of type 2 diabetes, population adherence to recommended exercise guidelines remains stubbornly low. Indeed, most adults are exposed to environmental settings (at work, in automobile travel and in the domestic environment) that may not only limit their physical activity, but also promote sitting for prolonged periods of time. However, recent experimental evidence indicates that reducing and breaking up sitting time may also be a useful strategy to improve glycaemic control...

Gross iron overload has long been known to result in diabetes mellitus. However, it is now thought that milder levels of iron overload, possibly within the normal range, also increase the risk of diabetes mellitus. The article by Rawal et al in this issue (Diabetologia doi: 10.1007/s00125-016-4149-3 ) provides further support for the relationship between mild degrees of iron overload and the risk of gestational diabetes. The purpose of this commentary is to briefly discuss the background of this relationship and the implications it may have for routine pregnancy care...

Type 1 diabetes is an immune-mediated disease leading to almost total beta cell destruction and permanent exogenous insulin dependency. The appearance of clinical symptoms is preceded by an asymptomatic preclinical period, the duration of which is highly individual. The emergence of diabetes-associated autoantibodies into the peripheral circulation is the first detectable sign of beta cell autoimmunity. If type 1 diabetes is diagnosed in childhood the preclinical period lasts for an average of 2.5-3 years, but clinical symptoms may in some cases appear within a few months or be delayed for more than 20 years...

Endotrophin is a cleavage product derived from the collagen VI(α3) chain. Collagen VI is expressed in a number of different tissues, but adipose tissue is a particularly prominent source for this extracellular matrix constituent. Mice lacking collagen VI are metabolically healthier due to reduced fibrosis in adipose tissue. Endotrophin seems to be one of the key players of collagen VI-mediated signalling effects, including its pro-fibrotic nature and chemoattractant properties for macrophages, while also playing an important role in cancer progression and the chemoresistance of tumour cells...

Oxidative stress has long been considered a key driving factor of many obesity-related health problems. However, recent work by Merry, Tran et al (Diabetologia DOI 10.1007/s00125-016-4084-3 ) challenges this idea with an interesting study using a hepatocyte-specific Gpx1-knockout (HGKO) mouse. GPX1 is an important detoxification enzyme that converts H2 O2 to water. The authors found that high-fat diet-fed HGKO mice were more insulin sensitive than wildtype controls, despite elevated hepatic levels of H2 O2 and evidence of increased systemic oxidative stress...

Steroid-induced hyperglycaemia is a common problem faced by endocrinologists in hospital wards. In this issue of Diabetologia, Popovic and colleagues (DOI 10.1007/s00125-016-4091-4 ) have conducted a subanalysis within a randomised controlled trial of prednisone therapy for community-acquired pneumonia. The authors found that the presence of diabetes or hyperglycaemia related to steroid therapy did not attenuate the clinical benefits of steroid therapy. The relevance and possible implications of these findings are discussed...
