Diabetes mellitus is a chronic disease defined as a state of hyperglycaemia in fasting or postprandial states. Patients with type 2 diabetes mellitus (T2DM) often show reduced physical function, including low levels of strength, balance or mobility. In this regard, the timed up and go (TUG) is a widely used physical fitness test in people with T2DM. However, there is a lack of studies evaluating the properties TUG in this population. The present study aimed to evaluate the test-retest reliability of kinetic and kinematic parameters obtained from TUG in the diabetic population with different levels of diabetic neuropathy. A total of 56 patients with T2DM participated in the study. They were divided into three groups according to the vibration threshold: (a) severe neuropathy, (b) moderate neuropathy and (c) normal perception. The TUG was performed using two force platforms to assess kinematic measurements. The results show that both kinetic and kinematic variables had good to excellent reliability. The reliability of TUG was excellent for the whole sample and the groups with non-severe neuropathy. However, it was just good for the group with severe neuropathy.

Background: Diabetes mellitus is a chronic disease characterized by fasting hyperglycemia. It affects approximately 415 million people worldwide and involves a variety of complications. One of them is the loss of sensitivity to peripheral vibration. Objective: Our study aims to discover the test-retest reliability of a procedure for assessing vibration sensitivity in people with type 2 diabetes mellitus. Methodology: 90 people with type 2 diabetes mellitus (56 men and 34 women) performed the vibration perception threshold (VPT) test using the Vibratron II device. A re-test was completed seven days after the first reading. Results: The relative reliability of the VPT test result is excellent (intraclass correlation coefficient = 0.96). The same applies to gender and obesity subgroups. Regarding absolute reliability, the standard error of measurement is 8.99%, and the small real difference is 24.94%. Conclusions: The relative and absolute reliability results of the vibration perception threshold in people with type 2 diabetes mellitus offer excellent results.

Background: Reliability studies are used to verify the evaluation accuracy of a given device. Strength is an important factor for the development of daily activities and its correct management is fundamental. The objective of this study was to examine the reliability of a concentric strength test in people with type 2 diabetes mellitus (T2DM). Methods: Twenty-seven individuals with T2DM performed three repetitions of extension-flexion in concentric-concentric action at 60°/s, for both legs, using an isokinetic dynamometer. For the reliability analysis, we performed an intra-session test retest. Results: The total sample and men sub-group intra-class correlation coefficient (ICC) values were excellent for peak torque and work. In the women sub-group, ICC values were excellent for extensors in both peak torque and work; however, concerning flexor, the ICC values were good for peak torque while, for work, they were good for the right leg and moderate for the left leg. Standard error of measurement (SEM) percentage oscillated from 3.85% to 6.80%, with the smallest real difference (SRD) percentage being from 10.66% to 18.86% for peak torque. Furthermore, the SEM (%) was around 5.5% and SRD (%) was around 15% for work. Conclusions: The isokinetic dynamometry had “good” to “excellent” relative reliability for peak torque (0.862–0.983) and work (0.744–0.982) of extension-flexion in concentric-concentric action at 60°/s. In addition, our study showed that, in general, an SRD < 20% could indicate a true change in strength regarding this protocol in T2DM.

Objective: Self-reported information from questionnaires is frequently used in epidemiological studies, but few of these studies provide information on the reproducibility of individual items contained in the questionnaire. We studied the test–retest reliability of self-reported diabetes among 33,919 participants in Norwegian Women and Cancer Study. Methods: The test–retest reliability of self-reported type 1 and type 2 diabetes diagnoses was evaluated between three self-administered questionnaires (completed in 1991, 1998, and 2005 by Norwegian Women and Cancer participants) by kappa agreement. The time interval between the test–retest studies was ~7 and ~14 years. Sensitivity of the kappa agreement for type 1 and type 2 diabetes diagnoses was assessed. Subgroup analysis was performed to assess whether test–retest reliability varies with age, body mass index, physical activity, education, and smoking status. Results: The kappa agreement for both types of self-reported diabetes diagnoses combined was good (⩾0.65) for all three test–retest studies (1991–1998, 1991–2005, and 1998–2005). The kappa agreement for type 1 diabetes was good (⩾0.73) in the 1991–2005 and the 1998–2005 test–retest studies, and very good (0.83) in the 1991–1998 test–retest study. The kappa agreement for type 2 diabetes was moderate (0.57) in the 1991–2005 test–retest study and good (⩾0.66) in the 1991–1998 and 1998–2005 test–retest studies. The overall kappa agreement in the 1991–1998 test–retest study was stronger than in the 1991–2005 test–retest study and the 1998–2005 test–retest study. There was no clear pattern of inconsistency in the kappa agreements within different strata of age, BMI, physical activity, and smoking. The kappa agreement was strongest among the respondents with 17 or more years of education, while generally it was weaker among the least educated group. Conclusion: The test–retest reliability of the diabetes was acceptable and there was no clear pattern of inconsistency in the kappa agreement stratified by age, body mass index, physical activity, and smoking. The study suggests that self-reported diabetes diagnosis from middle-aged women enrolled in the Norwegian Women and Cancer Study is reliable.

Introduction: Type 2 diabetes mellitus is a common disease, affecting up to 13.1% of the Portuguese population. In addition to the known micro and macrovascular complications, drug side effects constitute a major concern, leading to changes in the treatment guidelines, which favor safety over efficacy. Metformin is the first-line pharmacological treatment for most patients with type 2 diabetes mellitus; however, it has been associated with vitamin B12 deficiency in up to 30% of treated patients. The authors describe the prevalence of vitamin B12 deficiency in a diabetic population and explore the possible underlying factors.Material and Methods: Retrospective, observational study. Clinical and laboratory data of type 2 diabetes mellitus patients whose vitamin B12 status was evaluated in the last decade (2005 - 2016) were analyzed. Patients with known malabsorptive syndromes or having undergone bariatric surgery were excluded from the study. Statistical analysis of the data was done and the results were considered statistically significant at p values < 0.05.Results: The study included a total of 1007 patients (58% women) with a mean age of 66.4 ± 12.2 years and 11 ± 10.4 years of type 2 diabetes mellitus duration. These patients had a high prevalence of complications: diabetic renal disease 47.7%, neuropathy 9.2%, retinopathy 14.9%, coronary artery disease 8.4%, cerebrovascular disease 10.9%, and peripheral arterial disease 5.5%. Vitamin B12 deficiency (< 174 ng / dL) was present in 21.4% of the population and this subgroup was older (68.4 vs 65.8 years, p = 0.006), had a longer type 2 diabetes mellitus duration (13.35 vs 10.36 years; p = 0.001), higher prevalence of retinopathy (20.9% vs 13.3%; p = 0.005) and thyroid dysfunction (34% vs 23.7%; p = 0.002). Vitamin B12 deficiency was also more frequent in patients treated with metformin (24.7% vs 15.8%; p = 0.017), antiplatelet agents (25.4% vs 16.2%, p < 0.001), and calcium channel blockers (26.8% vs 18.2%; p = 0.001). After adjustment for possible confounders, the variables associated with B12 deficiency were: metformin, hypothyroidism, age and type 2 diabetes mellitus duration.Discussion: Despite the retrospective design, the results report a high prevalence of vitamin B12 deficiency in the type 2 diabetic population. This study also demonstrates that the B12 deficiency risk is higher in older people, with longer diabetes mellitus duration, hypothyroidism and treated with metformin.Conclusion: Further studies are needed to identify the risk factors for the B12 deficit. The recognition of these variables will contribute to optimize the screening and prevention of the B12 deficiency in type 2 diabetes mellitus.

Neutrophil Dysfunction

Lactoferrin (LF) is a protein that plays important roles in many diseases including diabetes mellitus (DM). DM is one of the most challenging health concerns of the 21st century. At least 30% of the diabetic population is undiagnosed at any one time, so effective and early diagnosis is of critical concern. Several of the body’s chemicals, such as enzymes, electrolytes, and proteins, have been used as biomarkers in the diagnosis of diabetic diseases. Detection of LF is considered an important sign of type 2 diabetes (T2DM), due to its activity as an anti-inflammatory agent and in the down-regulation of pro-inflammation. LF is produced by glandular epithelial cells and neutrophils, and a decrease in its concentration is linked with the dysfunction of neutrophils in many diseases. Neutrophils are the first line of defence against pathogens that invade the human body during inflammation. Therefore, the health of neutrophils can be employed as a biomarker in the diagnosis of diseases such as diabetes. A decrease in LF concentrations in T2DM could result in increased levels of inflammatory markers that are associated with the inflammation activity. Increased understanding of the link between LF concentration and development of T2DM should improve early diagnosis and treatment outcomes. LF is identified through use of various techniques such as immunoassay, proteomics, and spectrometry. The aim of this review is to summarise each pathway and some of the most relevant LF biomarkers that may be used to monitor the development or progression of diabetes and its complications, and the link between levels of LF and neutrophil dysfunction in T2DM. Moreover, the objective of this review is to show the most common LF analysis that may be useful in the clinical diagnosis of T2DM and discuss to what extent this analysis method can be a tool for prognostic and diagnostic work.

Morisky Scale

Background A self-reporting questionnaire is the most convenient and cheapest way to assess medication adherence. A new 8-item self-reported Morisky Medication Adherence Scale (MMAS) has been developed and has shown better psychometric properties than the original 4-item Morisky scale. Objective To examine the validity, including convergent known-groups and construct validity, and reliability, including internal consistency and test–retest reliability, of the MMAS in Thai patients with type 2 diabetes. Methods The data were derived from a cross-sectional study. In a convenience sample, 303 type 2 diabetic outpatients were interviewed at the General Police Hospital in Bangkok, Thailand, between January and June 2007. Face-to-face interviews included MMAS, medication adherence visual analog scale (MA-VAS), and sociodemographic data. Medical records were reviewed for clinical data such as hemoglobin A1c (A1C) levels. Results Internal consistency reliability was moderate (Cronbach's α = 0.61), whereas the test–retest reliability of the MMAS was excellent (intraclass correlation coefficient = 0.83; p < 0.001). Concerning convergent validity, the MMAS had a high correlation with the 3-item Morisky scale (r = 0.77; p < 0.01) and a medium correlation with the MA-VAS (r = 0.57; p < 0 01). Regarding known-groups validity, a significant association between MMAS and A1C levels was found (χ2 = 6.7; p < 0.05). The sensitivity, specificity, positive predictive value, and negative predictive value of the MMAS were 51%, 64%, 71%, and 43%, respectively. Our factor analysis showed that the MMAS had 3 dimensions including forgetting to take medications, stopping medications when feeling better or worse, and the complexity of the drug regimen. Conclusions The 8-item MMAS can be a tool to aid in assessing medication adherence in diabetes. The poor sensitivity can be improved by increasing the number of the response choices and the cut-off score of the scale and by using specific words in some items. A modified Thai version of the 8-item MMAS may be needed.
