Elevated plasma level of visfatin/pre-b cell colony-enhancing factor in male oral squamous cell carcinoma patients
Objectives: Visfatin, also known as nicotiamide phosphoribosyltransferase or pre-B cell colony enhancing factor,
is a pro-inflammatory cytokine whose serum level is increased in various cancers. In this study, we investigated
whether plasma visfatin levels were altered in patients with oral squamous cell carcinoma (OSCC). The relation
ship between plasma visfatin levels and the pretreatment hematologic profile was also explored.

esign: Plasma visfatin concentrations were measured through ELISA in OSCC patients and control sub
jects. A total of 51 patients with OSCC and 57 age- and body mass index (BMI)-matched control subjects were
studied. All study subjects were male.
Results: Plasma visfatin was found to be elevated in patients with OSCC (7.0 ± 4.5 vs. 4.8 ± 1.9 ng/ml, p = 0.002).
Multiple logistic regression analysis revealed visfatin as an independent association factor for OSCC, even after
full adjustment of known biomarkers. Visfatin level was significantly correlated with white blood cell (WBC)
count, neutrophil count, and hematocrit (all p < 0.05). In addition, WBC count, neutrophil count, and visfatin
gradually increased with stage progression, and hematocrit gradually decreased with stage progression (all p <
0.05).
Conclusion: Increased plasma visfatin levels were associated with OSCC, independent of risk factors, and were cor
related with inflammatory biomarkers. These data suggest that visfatin may act through inflammatory reactions to
play an important role in the pathogenesis of OSC
Cardiac Myosin Binding Protein C and MAP-Kinase Activating Death Domain-Containing Gene Polymorphisms and Diastolic Heart Failure
OBJECTIVE: Myosin binding protein C (MYBPC3) plays a role in ventricular relaxation. The aim of the study was to investigate the association between cardiac myosin binding protein C (MYBPC3) gene polymorphisms and diastolic heart failure (DHF) in a human case-control study. METHODS: A total of 352 participants of 1752 consecutive patients from the National Taiwan University Hospital and its affiliated hospital were enrolled. 176 patients diagnosed with DHF confirmed by echocardiography were recruited. Controls were matched 1-to-1 by age, sex, hypertension, diabetes, renal function and medication use. We genotyped 12 single nucleotide polymorphisms (SNPs) according to HapMap Han Chinese Beijing databank across a 40 kb genetic region containing the MYBPC3 gene and the neighboring DNA sequences to capture 100% of haplotype variance in all SNPs with minor allele frequencies ≥ 5%. We also analyzed associations of these tagging SNPs and haplotypes with DHF and linkage disequilibrium (LD) structure of the MYBPC3 gene. RESULTS: In a single locus analysis, SNP rs2290149 was associated with DHF (allele-specific p = 0.004; permuted p = 0.031). The SNP with a minor allele frequency of 9.4%, had an odds ratio 2.14 (95% CI 1.25-3.66; p = 0.004) for the additive model and 2.06 for the autosomal dominant model (GG+GA : AA, 95% CI 1.17-3.63; p = 0.013), corresponding to a population attributable risk fraction of 12.02%. The haplotypes in a LD block of rs2290149 (C-C-G-C) was also significantly associated with DHF (odds ratio 2.10 (1.53-2.89); permuted p = 0.029). CONCLUSIONS: We identified a SNP (rs2290149) among the tagging SNP set that was significantly associated with early DHF in a Chinese population
Congenital and Environmental Factors Associated with Adipocyte Dysregulation as Defects of Insulin Resistance
The metabolic syndrome refers to insulin resistance and its associated cluster of related cardiovascular metabolic risk factors including type 2 diabetes, hypertension, dyslipidemia and central obesity. Although many hypotheses and facts have been proposed to explain the interaction between genetic and environmental causes of this syndrome, the primary etiology of the metabolic syndrome is adipose tissue dysregulation. Firstly, the thrifty genotype and phenotype hypothesis may explain the endemic increase in type 2 diabetes and cardiovascular disease in developing countries and may elucidate congenital susceptibility to and environmental triggering of the metabolic syndrome. Secondly, overnutrition leads to fatty acid (FA) accumulation in adipocytes and to an overflow to ectopic fat storage organs. This causes functional changes in adipocytes shifting the intra-cellular metabolic pathway toward insulin resistance. Thirdly, obese subjects exhibit increased fat cell size and over-secretion of biologic adipocytokines. Fourthly, failure to adequately develop adipose tissue mass, as seen in lipodystrophy cases, causes severe insulin resistance and diabetes. Lastly, similarly to human type 2 diabetes, Psammonys obesus, a desert rat which feeds mainly on low-calorie vegetation, develops the metabolic syndrome when given a diet of calorie-rich food. The above evidence indicates that adipocyte dysregulation and secretion of FA as well as certain molecules from overloaded adipocytes-adipokines contribute to the pathogenesis of impaired insulin secretion and insulin resistance, endothelial dysfunction, a pro-inflammatory state and promote progression of atherosclerosis. The metabolic syndrome is a modern disease resulting in adipocyte dysmetabolism which originates from the paradox of slow human evolution combined with rapid environmental changes
Associations between Vitamin B-12 Status and Oxidative Stress and Inflammation in Diabetic Vegetarians and Omnivores
Diabetes is considered an oxidative stress and a chronic inflammatory disease. The purpose of this study was to investigate the correlations between vitamin B-12 status and oxidative stress and inflammation in diabetic vegetarians and omnivores. We enrolled 154 patients with type 2 diabetes (54 vegetarians and 100 omnivores). Levels of fasting glucose, glycohemoglobin (HbA1c), lipid profiles, oxidative stress, antioxidant enzymes activity, and inflammatory makers were measured. Diabetic vegetarians with higher levels of vitamin B-12 (>250 pmol/L) had significantly lower levels of fasting glucose, HbA1c and higher antioxidant enzyme activity (catalase) than those with lower levels of vitamin B-12 (≤250 pmol/L). A significant association was found between vitamin B-12 status and fasting glucose (r = −0.17, p = 0.03), HbA1c (r = −0.33, p = 0.02), oxidative stress (oxidized low density lipoprotein-cholesterol, r = −0.19, p = 0.03), and antioxidant enzyme activity (catalase, r = 0.28, p = 0.01) in the diabetic vegetarians; vitamin B-12 status was significantly correlated with inflammatory markers (interleukin-6, r = −0.33, p < 0.01) in diabetic omnivores. As a result, we suggest that it is necessary to monitor the levels of vitamin B-12 in patients with diabetes, particularly those adhering to a vegetarian diet
Effects of different blood pressures and their long-term variability on the development of diabetic kidney disease in patients with type 2 diabetes mellitus
Aim To explore the relationship between long-term variabilities in different blood pressure variables and diabetic kidney disease (DKD) in patients with type 2 diabetes. Design A retrospective study. Methods This study included 3050 patients with type 2 diabetes whose metabolic parameters were regularly checked. Intrapersonal means and standard deviations (SDs) of all recorded systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), and pulse pressure (PP) measurements were calculated. Subjects were divided into four groups: Q1 (SBP-Mean < 130, SBP-SD < 11.06); Q2 (SBP-Mean < 130, SBP-SD ≥ 11.06); Q3 (SBP-Mean ≥ 130, SBP-SD < 11.06); Q4 (SBP-Mean ≥ 130, SBP-SD ≥ 11.06). Similarly, based on whether the PP-Mean was higher or lower than 80 mmHg (average PP-Mean) and the PP-SD was higher or lower than 6.48 mmHg (average PP-SD), the involved patients were redivided into Q1’~ Q4’ groups. Results Adjusted for age, sex and diabetes duration, results revealed that the SBP-Mean, SBP-SD, PP-Mean and PP-SD were risk factors for DKD. Meanwhile, patients in the Q4 group had the highest DKD prevalence (HR = 1.976, p < .001), while Q1 group had the lowest. In addition, patients in the Q3 group (HR = 1.614, P < .001) had a higher risk of DKD than those in the Q2 group (HR = 1.408, P < .001). After re-stratification by PP-Mean and PP-SD, patients in the Q4’ group had the highest risk of DKD (HR = 1.370, p < .001), while those in the Q1’ group had the lowest risk. Patients in the Q3’ group (HR = 1.266, p < .001) had a higher risk of DKD than those in the Q2’ group (HR = 1.212, p < .001)
The association of obstructive sleep apnea and renal outcomes—a systematic review and meta-analysis
Abstract Background The aim of this systematic review and meta-analysis was to summarize the association of obstructive sleep apnea (OSA) with renal outcome. Methods Our study followed the PRISMA guidelines. Two independent reviewers searched for relevant articles in the databases of Pubmed, the Web of Science and CENTRAL, and conducted study selection and quality assessment. A random-effect model was used to estimate the effects. Results A total of 1240 articles were initially identified (Pubmed = 568, Web of Science = 640, CENTRAL = 32). After removal of duplicate articles (n = 415) and irrelevant articles (n = 788), 37 were selected for full-text review, and 18 were finally included in the analysis. Overall, patients diagnosed with OSA were found to have a higher odds ratio (OR) of a poorer renal outcome, with a pooled OR of 1.77 (95% C.I.: 1.37–2.29). The significant association between OSA and a poorer renal outcome was not affected by the medical condition of diabetes mellitus (DM). In addition, we found that OSA was consistently associated with higher albuminuria/proteinuria and a lower estimated glomerular filtration rate (eGFR), with a pooled OR of 1.84 (95% C.I.: 1.24–2.73) and 1.60 (95% C.I.: 1.19–2.16), respectively. A greater OSA severity was also found to be related to a higher OR, with a mild group OR of 1.45 (95% C.I.: 1.19–1.77) and a moderate and severe group OR of 2.39 (95% C.I.: 1.96–2.90). Conclusions Our study demonstrated that OSA is significantly associated with poorer renal function
Association of Possible Sarcopenia or Sarcopenia with Body Composition, Nutritional Intakes, Serum Vitamin D Levels, and Physical Activity among Patients with Type 2 Diabetes Mellitus in Taiwan
This study estimates the association between sarcopenia and blood biochemical parameters, nutritional intake, anthropometric measurements, physical performance, and physical activity in patients with type 2 diabetes mellitus (T2DM). Participants were recruited from a primary care clinic in Kaohsiung City. According to the diagnosis criteria of the Asian Working Group for Sarcopenia (AWGS) in 2019, 110 patients with T2DM (aged 50–80 years) were divided into three groups: non-sarcopenia (n = 38), possible sarcopenia (n = 31), and sarcopenia (n = 41). Blood samples were collected, and nutritional intake was evaluated by a registered dietitian. A food frequency questionnaire and a Godin leisure-time exercise questionnaire were used to assess their daily vitamin D intake and physical activity. There were significant differences in age, serum vitamin D levels, nutritional intake, anthropometric measurements, and physical performance between the three groups. In elderly patients with T2DM, reduced serum 25-hydroxyvitamin D [25(OH)D] levels and daily energy intake were significantly associated with possible sarcopenia. Age, lower BMI, reduced serum 25(OH)D, and reduced dietary protein and vitamin D intake were significantly associated with sarcopenia. These findings may serve as the basis for intervention trials to reduce the prevalence of sarcopenia
A Case of Acquired Generalized Lipodystrophy with Cerebellar Degeneration and Type 2 Diabetes Mellitus
Acquired generalized lipodystrophy (AGL) is a rare disorder of adipose tissue characterized by loss of fat from large regions of the body, occurring after birth. Its etiology remains unknown. Most AGL patients have had fasting and/or postprandial hyperinsulinemia, diabetes mellitus, hypertriglyceridemia, and fatty liver. We describe the case of a 30-year-old woman with a progressively unsteady gait and a generalized loss of body fat beginning at the age of 7. Cerebellar degeneration was revealed by imaging study, and the patient was eventually bedridden at the age of 15, due to progressive ataxia. She developed diabetes at the age of 25 without the presence of any evidence of ketoacidosis. The glutamic acid decarboxylase antibody was negative, C-peptide level 3.6 ng/ml, HbA1c 13%, triglyceride 412 mg/dl, total cholesterol 196 mg/dl, high-density lipoprotein-cholesterol 28 mg/dl, adiponectin 0.76 μg/ml, and resistin was 22.8 ng/ml at the initial state of diabetes. AGL accompanied by type 2 diabetes and cerebellar degeneration was diagnosed on the basis of the clinical features and metabolic derangements
The Related Risk Factors of Diabetic Retinopathy in Elderly Patients with Type 2 Diabetes Mellitus: A Hospital-Based Cohort Study in Taiwan
Diabetic retinopathy (DR), caused by small vessel disease, is the main cause of blindness in persons with diabetes. Taiwan is one of the Asian countries with the highest prevalence rate of DR. The purpose was to investigate the related risk factors of DR in elderly patients with type 2 diabetes mellitus (T2DM), in Lee’s Endocrinology Clinic. 792 T2DM patients over 60 years old were invited to have an outpatient visit at least every three months, and all of them were asked to undergo a standardized interview and collect their blood samples. Significant factors were being female (adjusted hazard ratio (HR): 1.287; 95% CI, 1.082–1.531), higher glycated hemoglobin (HbA1c) (HR: 1.067; 95% CI: 1.016–1.119), higher mean low density of lipoprotein cholesterol (LDL-c) (HR: 1.004; 95% CI: 1.001–1.006), and chewing betel nut (HR: 1.788; 95% CI: 1.362–2.347). This study showed that gender, the behavior of chewing betel nut, HbA1c, and LDL-c are important factors for the development of DR in elderly patients with T2DM. It is suggested that patients should control their HbA1c and LDL-c and quit chewing betel nut to prevent DR. This suggestion applies especially to female patients
Quality of care and prescription patterns among patients with diabetic kidney disease—a large-scale cohort study from Taiwanese clinics
Aims To investigate the quality of care and prescription patterns of patients with diabetic kidney disease (DKD) receiving primary care at local clinics in Taiwan. Methods A retrospective chart review was conducted in 43 primary care clinics in Taiwan. The patients’ baseline characteristics, laboratory tests, presence of complications and antidiabetic agents prescribed were analyzed. Results 7,200 patients with type 2 diabetes mellitus were enrolled. Percentage of HbA1c, blood pressure (BP), and low density lipoprotein cholesterol (LDL-C) goals reached were 52.5% in HbA1c < 7%, 40.9% in BP < 130/80 mmHg and 79.7% in LDL-C < 2.59 mmol/L. 18.3% achieved all three ABC goals. However, patients with DKD had a lower rate of ABC goal attainment and higher rate of complications. Among DKD patients with eGFR ≥ 30 ml/min/1.73 m2 and on monotherapy, metformin was most frequently prescribed. As for dual therapy, the most common combinations were metformin with sulfonylurea and metformin with DPP-4 inhibitors. Conclusions Diabetes patients in Taiwan receiving primary diabetes care at local clinics had generally satisfactory management performance. However, more aggressive HbA1c, BP, and LDL-C management among DKD patients should be emphasized. Contrary to current recommendations, SGLT-2 inhibitors and GLP-1 receptor agonists as frontline therapy were under-prescribed
