OBJECTIVE—There is conflicting evidence regarding the benefit of intravenous insulin therapy on mortality following acute myocardial infarction (AMI). The goal of the current study was to determine whether improved glycemic control, achieved through an insulin/dextrose infusion with a variable rate of insulin, reduces mortality among hyperglycemic patients with AMI. RESEARCH DESIGN AND METHODS—Subjects suffering AMI with either known diabetes or without diabetes but blood glucose level (BGL) ≥7.8 mmol/l were randomized to receive insulin/dextrose infusion therapy for at least 24 h to maintain a BGL <10 mmol/l or conventional therapy. RESULTS—A total of 240 subjects were recruited. Insulin/dextrose infusion did not reduce mortality at the inpatient stage (4.8 vs. conventional 3.5%, P = 0.75), 3 months (7.1 vs 4.4%, P = 0.42), or 6 months (7.9 vs. 6.1%, P = 0.62). There was, however, a lower incidence of cardiac failure (12.7 vs. 22.8%, P = 0.04) and reinfarction within 3 months (2.4 vs. 6.1%, P = 0.05). When analyzed by mean BGL achieved during the first 24 h, mortality was lower among subjects with a mean BGL ≤8 mmol/l, compared with subjects with a mean BGL >8 mmol/l (2 vs. 11% at 6 months, P = 0.02). CONCLUSIONS—We did not find a reduction in mortality among patients who received insulin/dextrose infusion therapy. However, it remains possible that tight glycemic control with insulin therapy following AMI improves outcomes.

BackgroundPeople with uncontrolled diabetes are at greater risk for several oral health problems, particularly periodontal (gum) disease. Periodontal disease also impacts diabetes control. Good oral hygiene and regular dental visits are recommended to prevent and manage oral health problems. Several studies have been conducted to assess the oral health knowledge, attitudes, and practices of people with diabetes yet a review of these findings has not yet been undertaken. The aim of this systematic review was to synthesize current evidence on the knowledge, attitudes and practices of people with diabetes in relation to their oral health care.MethodsA systematic search of all literature was carried out in five databases using key search terms. The inclusion criteria were: 1) published in the English language; 2) from 2000 to November, 2017; 3) conducted on persons with any type of diabetes and of all ages; 4) explored at least one study outcome (knowledge or attitude or practices toward oral health care); and 5) used quantitative methods of data collection. No restrictions were placed on the quality and setting of the study.ResultsA total of 28 studies met the inclusion criteria. The studies included a total of 27,894 people with diabetes and were conducted in 14 countries. The review found that people with diabetes have inadequate oral health knowledge, poor oral health attitudes, and fewer dental visits. They rarely receive oral health education and dental referrals from their care providers. Provision of oral health education by diabetes care providers and referral to dentists when required, was associated with improved oral health behaviours among patients.ConclusionsOverall, people with diabetes have limited oral health knowledge and poor oral health behaviours. It is therefore essential to educate patients about their increased risk for oral health problems, motivate them for good oral health behaviours and facilitate access to dental care.Electronic supplementary materialThe online version of this article (10.1186/s12889-018-5485-7) contains supplementary material, which is available to authorized users.

Ethnicity is defined as "belonging to a social group that has a common national or cultural tradition". Membership of certain ethnic groups has long been associated with increased risk of gestational diabetes mellitus (GDM). Studies that examined ethnic differences amongst women with GDM were often conducted in western countries where women from various ethnic backgrounds were represented. The prevalence of GDM appears to be particularly high among women from South Asia and South East Asia, compared to Caucasian, African-American and Hispanic communities. For some, but not all ethnic groups, the body mass index is a risk factor for the development of GDM. Even within a particular ethnic group, those who were born in their native countries have a different risk profile for GDM compared to those born in western countries. In terms of treatment, medical nutrition therapy (MNT) plays a key role in the management of GDM and the prescription of MNT should be culturally sensitive. Limited studies have shown that women who live in an English-speaking country but predominantly speak a language other than English, have lower rates of dietary understanding compared with their English speaking counterparts, and this may affect compliance to therapy. Insulin therapy also plays an important role and there appears to be variation as to the progression of women who progress to requiring insulin among different ethnicities. As for peri-natal outcomes, women from Pacific Islander countries have higher rates of macrosomia, while women from Chinese backgrounds had lower adverse pregnancy outcomes. From a maternal outcome point of view, pregnant women from Asia with GDM have a higher incidence of abnormal glucose tolerance test results post-partum and hence a higher risk of future development of type 2 diabetes mellitus. On the other hand, women from Hispanic or African-American backgrounds with GDM are more likely to develop hypertension post-partum. This review highlights the fact that management needs to be individualised and the clinician should be mindful of the impact that differences in ethnicity may have on the clinical characteristics and pregnancy outcomes in women affected by GDM, particularly those living in Western countries. Understanding these differences is critical in the delivery of optimal antenatal care for women from diverse ethnic backgrounds.

Our study suggests that IFN therapy may provoke two different forms of thyrotoxicosis: a Graves' disease picture or a biphasic thyroiditis pattern. The two entities should be differentiated, as they have different implications for treatment.

Aims/hypothesis Identifying women with gestational diabetes mellitus who are more likely to require insulin therapy vs medical nutrition therapy (MNT) alone would allow risk stratification and early triage to be incorporated into risk-based models of care. The aim of this study was to develop and validate a model to predict therapy type (MNT or MNT plus insulin [MNT+I]) for women with gestational diabetes mellitus (GDM). Methods Analysis was performed of de-identified prospectively collected data from women diagnosed with GDM by criteria in place since 1991 and formally adopted and promulgated as part of the more detailed 1998 Australasian Diabetes in Pregnancy Society management guidelines. Clinically relevant variables predictive of insulin therapy by univariate analysis were dichotomised and included in a multivariable regression model. The model was tested in a separate clinic population. Results In 3317 women, seven dichotomised significant independent predictors of insulin therapy were maternal age >30 years, family history of diabetes, pre-pregnancy obesity (BMI ≥30 kg/m 2 ), prior GDM, early diagnosis of GDM (<24 weeks gestation), fasting venous blood glucose level (≥5.3 mmol/l) and HbA 1c at GDM diagnosis ≥5.5% (≥37 mmol/mol). The requirement for MNT+I could be estimated according to the number of predictors present: 85.7-93.1% of women with 6-7 predictors required MNT+I compared with 9.3-14.7% of women with 0-1 predictors. This model predicted the likelihood of several adverse outcomes, including Caesarean delivery, early delivery, large for gestational age and an abnormal postpartum OGTT. The model was validated in a separate clinic population. Conclusions/interpretation This validated model has been shown to predict therapy type and the likelihood of several adverse perinatal outcomes in women with GDM.

Women with GDM who require insulin therapy differ from those who can be managed on MNT alone. Being aware of factors that predict failure of MNT could help diabetes services develop a more efficient model of care in the management of women with GDM.
