Anemia, defined as a reduction in the hemoglobin concentration of blood, is common in diabetes mellitus (DM) patients, can be potentially caused by diabetes complications such as nephropathy. Recent research suggests that diabetes mellitus (DM) itself may be a major risk factor of anemia. However, there are few Korean studies on the relationship between diabetes mellitus (DM) and anemia. This study was performed to investigate the association between anemia and diabetes mellitus (DM) in Korean adults. A total of 10,151 Korean adults over aged 19 years (4,422 male, 5,729 female) were selected from the participants of the Korean National Health and Nutrition Examination Survey VI (KNHANES VI). Korean adults with anemia had a higher prevalence of diabetes mellitus (DM) than the normal adults (11.4% vs. 30.4% in male, 8.8% vs. 9.4% in female). The unadjusted odds ratio (OR) for anemia was greater in adults with DM than in normal male (OR=3.28; 95% CI: 2.27~4.73). After adjusting for other risk factors including age, education, family income, smoking, drinking, and menstrual status, anemia and diabetes were not associated (OR=1.33; 95% CI: 0.84~2.09). Similarly, there was no association between anemia and diabetes in female. In conclusion, this study shows that the prevalence of anemia is similar in diabetic and non-diabetic Korean adults after adjusting for multiple risk factors. Further research is required to elucidate the mechanism of anemia caused as a consequence of diabetes mellitus (DM).

Diabetes Mellitus (DM), often simply referred to as diabetes, has developed into a major health concern affecting more than 200 million people worldwide with approximately 4 million deaths per year attributed to the presence of the disease. Diabetes mellitus is categorized as Type 1 and Type 2, where Type 1 diabetes represents a lack of insulin production, and Type 2 diabetes is characterized by a relative lack of insulin receptor (i.e., decreased sensitivity to the effect of insulin) and cased by a complex interplay between genetic factors and environmental factors. Up to date, various studies on the pathology and mechanism in terms of genetic experiments have been conducted and approximately hundreds of genes were reported as diabetes mellitus associated genes. At this point, to support studies on the cause and mechanism of diabetes mellitus, an efficient database system to provide genetic variants related to diabetes mellitus is needed. DMBase is an integrated web-based genetic information resource for diabetes mellitus designed to service genomic variants, genes, and secondary information derived for diabetes mellitus genetics researchers. The current version of DMBase documents 754 genes with 3056 genetic variants and 66 pathways. It provides many effective search interfaces for retrieving diabetes mellitus and genetic information. A web interface for the DMBase is freely available at http://sysbio.kribb.re.kr/dmBase.

Latent autoimmune diabetes in adults (LADA) is a heterogeneous disease characterized by a less intensive autoimmune process and a broad clinical phenotype compared to classical type 1 diabetes mellitus (T1DM), sharing features with both type 2 diabetes mellitus (T2DM) and T1DM. Since patients affected by LADA are initially insulin independent and recognizable only by testing for islet-cell autoantibodies, it could be difficult to identify LADA in clinical setting and a high misdiagnosis rate still remains among patients with T2DM. Ideally, islet-cell autoantibodies screening should be performed in subjects with newly diagnosed T2DM, ensuring a closer monitoring of those resulted positive and avoiding treatment of hyperglycaemia which might increase the rate of ${\beta}-cells$ loss. Thus, since the autoimmune process in LADA seems to be slower than in classical T1DM, there is a wider window for new therapeutic interventions that may slow down ${\beta}-cell$ failure. This review summarizes the current understanding of LADA, by evaluating data from most recent studies, the actual gaps in diagnosis and management. Finally, we critically highlight and discuss novel findings and future perspectives on the therapeutic approach in LADA.

Objectives: The purpose of the study was to examine the association between diabetes mellitus and community periodontal index in Korean adults. Methods: The study populations were recruited by the Fifth Korea National Health and Nutrition Examination Survey. Study subjects were 10,411 who were examined oral examination, blood test, and aged over 19 years. Using multiple logistic regression analyses, the variables were adjusted for gender, age, household income, family history of diabetes, body mess index, smoking habit, and frequency of tooth brushing. Periodontal tissue examination of the subjects was performed and scored by Community periodontal index(CPI). Using probe, six teeth were examined for hemorrhage, plaque, and pocket depth and classified into $CPI_0$, $CPI_1$, $CPI_2$, $CPI_3$ and $CPI_4$. Healthy periodontal groups($CPI_{0-2}$) and periodontal disease groups($CPI_{3-4}$) were divided by the periodontal disease status. The definition of diabetes mellitus(DM) was decided by the diagnosis by the doctors and fasting blood sugar level. Those who were diagnosed as DM were included in DM group. The DM variables included normal blood sugar level, increased fasting blood sugar level, and DM blood sugar level. The DM variables were compared to periodontal disease blood sugar level and analyzed. Results: The periodontitis prevalence rate was 23.2%. Those who had diabetes mellitus accounted for 5.5% of the subjects. Those who had impaired fasting glucose accounted for 17.7% and 7.9% of subjects were diabetes mellitus by blood test. In the confirmed diabetes group by doctor, the periodontitis prevalence rate was significantly higher than the non-diabetic group. Diabetic group by blood test had the highest prevalence rate of periodontitis than those who had impaired fasting glucose group or normal group. After adjusting for gender, age, household income, family history of diabetes, body mass index, smoking habit, and frequency of tooth brushing, the risk of periodontitis in diagnosed diabetes mellitus was 1.57 times(95% CI; 1.27-1.94) higher than the normal group. In impaired fasting glucose group and diabetes mellitus group by blood test, the risk of periodontitis was 1.11 times(95% CI; 0.95-1.30) and 1.45 times(95% CI; 1.45-2.12) higher, respectively. Conclusions: There was a significant relationship between diabetes mellitus and periodontitis in Korean adults. These results suggest that diabetes mellitus is a risk factor for periodontitis.

Aim: The purpose of this study was to identify dominant pathogens and their antimicrobial susceptibilities of endodontic infection in type II diabetes mellitus (DM) patients to determine effective empirical antibiotics. Methodology: Pathogens from endodontic infection in six patients with DM and in six patients without DM were cultured, identified and their antimicrobial susceptibility was tested using Vitek2 systems ($bioM{\acute{e}}rieux$, Marcy l' Etoile, France). The results were analyzed using Chi-square test and Fisher's exact test at P< 0.05 level. Results: Pathogens of opportunistic infection were dominant in DM patients (P=0.015). However, there was no significant difference of antimicrobial susceptibility between DM and non-DM patients. Relatively high percent (27%) of pathogens showed resistance to penicillin. Conclusions: More cautions should be paid to DM patients because they are prone to opportunistic infection. Penicillin is not effective in the control of endodontic infection.

Objective: Older persons with diabetes mellitus (DM) are particularly more likely to have fallen in the previous year than those without DM. The purpose of this study was to investigate the relationship between the risk of falls and type 2 DM in older adults who are 65 years of age or above. Design: A systematic review. Methods: PubMed and other two databases were searched up to August 2, 2018. Observational and cohort studies evaluating fall risk in people who are 65 years of age or above with DM were included. This review extracted the following information from each study selected: first author's surname, year of publication, country, average follow-up period, sex, age at enrollment, study population, measurement variables, relative risk, 95% confidence intervals and controlled variables. Results: This review involved nine cohort studies with 3,765 older adults with DM and 12,989 older adults without DM. Six studies compared with or without DM and two studies compared fallers with non-fallers with DM. Risk factors for falls included impaired cognitive function, diabetes-related complications (peripheral nerve dysfunction, visual impairment), and physical function (balance, gait velocity, muscle strength, and severity of physical activities). Conclusions: People who are 65 years of age or above with DM have increased risk of falling caused by impaired cognitive function, peripheral nerve dysfunction, visual impairment, and physical function in community-dwellers. For adults who are 65 years of age or older with DM, research fields and clinical settings should consider therapeutic approaches to improve these risk factors for falls.

The incidence of type 1 diabetes mellitus (T1DM) in children and adolescents is increasing worldwide. Combined effects of genetic and environmental factors cause T1DM, which make it difficult to predict whether an individual will inherit the disease. Due to the level of self-care necessary in T1DM maintenance, it is crucial for pediatric settings to support achieving optimal glucose control, especially when adolescents are beginning to take more responsibility for their own health. Innovative insulin delivery systems, such as continuous subcutaneous insulin infusion (CSII), and noninvasive glucose monitoring systems, such as continuous glucose monitoring (CGM), allow patients with T1DM to achieve a normal and flexible lifestyle. However, there are still challenges in achieving optimal glucose control despite advanced technology in T1DM administration. In this article, disease prediction and current management of T1DM are reviewed with special emphasis on biomarkers of pancreatic ${\beta}-cell$ stress, CSII, glucose monitoring, and several other adjunctive therapies.

Prader-Willi syndrome (PWS) often develops type 2 diabetes mellitus (T2DM) related to severe obesity. The prevalence of T2DM in adults with PWS (7-20%) exceeds greatly the prevalence in the general population (5-7%). It is uncommon for pre-pubertal children with PWS to develop overt diabetes or glucose intolerance. GH therapy and genotype did not influence the development of altered glucose metabolism. It has been assumed that T2DM in PWS develops as a consequence of morbid obesity and concomitant insulin resistance. However recent studies suggest the relationship between morbid obesity and T2DM development is more complex and appears to differ in PWS subjects compared to non-PWS subjects. PWS patients had relatively lower fasting insulin levels and increased adiponectin levels compared with BMI-matched obese control despite of similar levels of leptin. So PWS children may be protected to some extent form of obesity-associated insulin resistance. Although there's no data, it seems logical to approach diabetes management including weight loss and increased exercise, using similar pharmacological agents as with non-PWS obesity-related diabetes such as metformin or thiazolidinedione, with the introduction of insulin as required. On the other hand, several recent T2DM in PWS case reports suggest favorable outcomes using Glucagon-like peptide 1 (GLP-1) analog with regard to ghrelin reduction, control of glucose and appetite, weight loss and pre-prandial insulin secretion. The role of GLP-1 agonist therapy is promising, but has not yet been fully elucidated.

Anemia is common in Diabetes Mellitus(DM) with chronic kidney disease. Recent research suggests that DM itself also may be a risk factor of anemia even though kidney failure causes anemia. However, it has not been reported that the impact of DM on anemia in representative data of Korean population. A total of 5,417 Korean adults aged 20 years and older(2,328 men, 3,089 women) were selected from the participants of the 2005 Korean National Health and Nutrition Examination Survey(KNHANES) for this study. Anemia was defined as hemoglobin(Hb) < 13 g/dL and hematocrit(Hct) < 39% for men or Hb < 12 g/dL and Hct < 36% for women. DM was defined as a fasting blood glucose $\geq$ 126 mg/dL. Korean adults with anemia had a higher prevalence of DM than in normal adults(11.4 vs 7.5%; p<0.0001). The unadjusted odds ratio(OR) for anemia was greater in Korean men with DM than in normal men(OR=4.25; 95% CI: 2.48-7.29). This results did not differ after adjustment for the putative risk factors for anemia including chronic disease(OR=2.64; 95% CI: 1.45-4.83). However, the presence of DM was not related with anemia in Korean women. In conclusion, this study revealed that DM might be an independent risk factor for anemia in Korean men. Identification and management for anemia are needed in Korean population with DM as well.

Objective: The differences between type 1 and type 2 diabetes mellitus (T1DM and T2DM) in terms of their adverse effects on male reproductive parameters have never been elucidated. This study aimed to distinguish between the effects of the DM types in mice treated with multiple low doses of streptozotocin (STZ) to mimic human T1DM and coadministered a high-fat diet (HFD) to mimic human T2DM. Methods: The T1DM mice were intraperitoneally injected with STZ (40 mg/kg body weight) for 5 days. The T2DM mice received an HFD for 14 days prior to STZ injection (85 mg/kg body weight), followed by continuous feeding of an HFD. Male reproductive parameters were evaluated. Results: The reproductive organs of the DM mice weighed significantly less than those of controls, and the seminal vesicles plus prostates of the T1DM mice weighed less than those of the T2DM mice. Increased sperm abnormalities and incomplete DNA packaging were observed in the DM groups. Sperm concentration and the proportion of normal sperm were significantly lower in the T1DM group. The seminiferous histopathology of DM mice was classified into seven types. The penises of the DM mice were smaller than those of the controls; however, tunica albuginea thickness and the amount of penile collagen fibers were increased in these mice. Round germ cells were abundant in the epididymal lumens of the mice with DM. Conclusion: T1DM adversely affected reproductive parameters to a greater extent than T2DM.
