Relation between BMI and diabetes mellitus and its complications among US older adults

Perceived musculoskeletal discomfort and its association with postural shifts during 4-h prolonged sitting in office workers

This study examined the characteristics of perceived discomfort and postural shifts at different magnitudes during a 4-h sitting period and the association between perceived discomfort and number of postural shifts. Forty healthy participants continuously typed a standardized text passage at a computer work station for 4 h. Subjects rated perceived body discomfort using Borg's CR-10 scale in 10 body regions (i.e. neck, shoulder, elbow, wrist/hand, upper back, lower back, buttock, thigh, knee, and ankle/foot). A seat pressure mat device was used to gather seat pressure data during sitting. Postural shifts were determined by analysis of the dispersion index of both ischial tuberosities from seat pressure data. The threshold for a postural shift was set at ±10% and ±20%. Perceived discomfort in all body regions increased continuously during a 4-h sitting period. The body regions with the highest perceived discomfort were the low back, buttocks, upper back, thigh, and neck. The average (±SD) numbers of postural shifts during the 1st, 2nd, 3rd, and 4th hour of sitting were 14.8 ± 9.5, 17.8 ± 9.4, 18.2 ± 11.1, and 18.1 ± 9.8 shifts per hour for the 10% threshold, and were 4.8 ± 4.4, 6.0 ± 5.6, 7.4 ± 6.7, and 7.7 ± 6.6 shifts per hour for the 20% threshold, respectively. Prolonged sitting led to an increase in perceived musculoskeletal discomfort over time. The number of postural shifts at both magnitudes increased in the first 2 h of sitting and, in the second 2-h period of sitting, only the number of larger postural shifts (with 20% threshold) increased. The findings extend our understanding of sitting behaviors.

Risk assessment for foot ulcers among Tunisian subjects with diabetes: a cross sectional outpatient study

BACKGROUND

Diabetic foot is an underestimated and redoubtable diabetes complication. The aims of our study were to assess diabetic foot ulcer risk factors according to International Working Group on the Diabetic Foot (IWGDF) classification, stratify patients into risk categories and identify factors associated with higher-risk grade.

METHODS

Cross-sectional setting over a period of 07 months, patients were randomly selected from the diabetic outpatients attending our unit of diabetology. Questionnaire and clinical examination were made by the same physician. Patients free of active foot ulcer were included.

RESULTS

Among 230 patients evaluated, 10 had an active foot ulcer and were excluded. Five patients (2.27%) had a history of foot ulcer and 3(1.36%) had a lower-limb amputation. Sensory neuropathy, as measured by the 5.07(10 g) Semmes-Weinstein monofilament testing, was present in 23.63% of patients, whereas 36.82% had a peripheral arterial disease based on clinical findings, and 43.63% had foot deformities. According to the IWGDF classification, Group 0: 72.72%, Group 1: 5.9%, Group 2: 17.73% and Group 3: 3.63%. After univariate analysis, patients in higher-risk groups were significantly more often female, had higher age and BMI, longer diabetes duration, elevated waist circumference, low school level, retinopathy and hyperkeratosis. Multivariate logistic regression analysis identified 3 significant independent factors associated with high-risk groups: retinopathy (OR = 2.529, CI95 [1.131-5.655], p = 0.024), hyperkeratosis (OR = 2.658, CI95 [1.222-5.783], p = 0.014) and school level (OR = 0.489, CI95 [0.253-9.44], p = 0.033).

CONCLUSIONS

Risk factors for foot ulceration were rather common in outpatients with diabetes. The screening of patients at risk for foot ulceration should start early, integrated with sustainable patient education.

Effect of Gastric Bypass vs Best Medical Treatment on Early-Stage Chronic Kidney Disease in Patients With Type 2 Diabetes and Obesity: A Randomized Clinical Trial

Importance

Early-stage chronic kidney disease (CKD) characterized by microalbuminuria is associated with future cardiovascular events, progression toward end-stage renal disease, and early mortality in patients with type 2 diabetes.

Objective

To compare the albuminuria-lowering effects of Roux-en-Y gastric bypass (RYGB) surgery vs best medical treatment in patients with early-stage CKD, type 2 diabetes, and obesity.

Design, Setting, and Participants

For this randomized clinical trial, patients with established type 2 diabetes and microalbuminuria were recruited from a single center from April 1, 2013, through March 31, 2016, with a 5-year follow-up, including prespecified intermediate analysis at 24-month follow-up.

Intervention

A total of 100 patients with type 2 diabetes, obesity (body mass indexes of 30 to 35 [calculated as weight in kilograms divided by height in meters squared]), and stage G1 to G3 and A2 to A3 CKD (urinary albumin-creatinine ratio [uACR] >30 mg/g and estimated glomerular filtration rate >30 mL/min) were randomized 1:1 to receive best medical treatment (n = 49) or RYGB (n = 51).

Main Outcomes and Measures

The primary outcome was remission of albuminuria (uACR <30 mg/g). Secondary outcomes were CKD remission rate, absolute change in uACR, metabolic control, other microvascular complications, quality of life, and safety.

Results

A total of 100 patients (mean [SD] age, 51.4 [7.6] years; 55 [55%] male) were randomized: 51 to RYGB and 49 to best medical care. Remission of albuminuria occurred in 55% of patients (95% CI, 39%-70%) after best medical treatment and 82% of patients (95% CI, 72%-93%) after RYGB (P = .006), resulting in CKD remission rates of 48% (95% CI, 32%-64%) after best medical treatment and 82% (95% CI, 72%-92%) after RYGB (P = .002). The geometric mean uACRs were 55% lower after RYGB (10.7 mg/g of creatinine) than after best medical treatment (23.6 mg/g of creatinine) (P < .001). No difference in the rate of serious adverse events was observed.

Conclusions and Relevance

After 24 months, RYGB was more effective than best medical treatment for achieving remission of albuminuria and stage G1 to G3 and A2 to A3 CKD in patients with type 2 diabetes and obesity.

Investigation of geographic disparities of pre-diabetes and diabetes in Florida

BACKGROUND

Diabetes is a leading cause of death and disability in the United States, and its precursor, pre-diabetes, is estimated to occur in one-third of American adults. Understanding the geographic disparities in the distribution of these conditions and identifying high-prevalence areas is critical to guiding control and prevention programs. Therefore, the objective of this study was to investigate clusters of pre-diabetes and diabetes risk in Florida and identify significant predictors of the conditions.

METHODS

Data from the 2013 Behavioral Risk Factor Surveillance System were obtained from the Florida Department of Health. Spatial scan statistics were used to identify and locate significant high-prevalence local clusters. The county prevalence proportions of pre-diabetes and diabetes and the identified significant clusters were displayed in maps. Logistic regression was used to identify significant predictors of the two conditions for individuals living within and outside high-prevalence clusters.

RESULTS

The study included a total of 34,186 respondents. The overall prevalence of pre-diabetes and diabetes were 8.2 and 11.5%, respectively. Three significant (p < 0.05) local, high-prevalence spatial clusters were detected for pre-diabetes, while five were detected for diabetes. The counties within the high-prevalence clusters had prevalence ratios ranging from 1.29 to 1.85. There were differences in the predictors of the conditions based on whether respondents lived within or outside high-prevalence clusters. Predictors of both pre-diabetes and diabetes regardless of region or place of residence were obesity/overweight, hypertension, and hypercholesterolemia. Income and physical activity level were significant predictors of diabetes but not pre-diabetes. Arthritis, sex, and marital status were significant predictors of diabetes only among residents of high-prevalence clusters, while educational attainment and smoking were significant predictors of diabetes only among residents of non-cluster counties.

CONCLUSIONS

Geographic disparities of pre-diabetes and diabetes exist in Florida. Information from this study is useful for guiding resource allocation and targeting of intervention programs focusing on identified modifiable predictors of pre-diabetes and diabetes so as to reduce health disparities and improve the health of all Floridians.

Gut microbiota of obese and diabetic Thai subjects and interplay with dietary habits and blood profiles

Obesity and type 2 diabetes mellitus (T2DM) have become major public health issues globally. Recent research indicates that intestinal microbiota play roles in metabolic disorders. Though there are numerous studies focusing on gut microbiota of health and obesity states, those are primarily focused on Western countries. Comparatively, only a few investigations exist on gut microbiota of people from Asian countries. In this study, the fecal microbiota of 30 adult volunteers living in Chiang Rai Province, Thailand were examined using next-generation sequencing (NGS) in association with blood profiles and dietary habits. Subjects were categorized by body mass index (BMI) and health status as follows; lean (L) = 8, overweight (OV) = 8, obese (OB) = 7 and diagnosed T2DM = 7. Members of T2DM group showed differences in dietary consumption and fasting glucose level compared to BMI groups. A low level of high-density cholesterol (HDL) was observed in the OB group. Principal coordinate analysis (PCoA) revealed that microbial communities of T2DM subjects were clearly distinct from those of OB. An analogous pattern was additionally illustrated by multiple factor analysis (MFA) based on dietary habits, blood profiles, and fecal gut microbiota in BMI and T2DM groups. In all four groups, Bacteroidetes and Firmicutes were the predominant phyla. Abundance of Faecalibacterium prausnitzii, a butyrate-producing bacterium, was significantly higher in OB than that in other groups. This study is the first to examine the gut microbiota of adult Thais in association with dietary intake and blood profiles and will provide the platform for future investigations.

Association between obesity indicators and cardiovascular risk factors among adults in low-income Han Chinese from southwest China

There may be differences in optimal anthropometric cut-offs for diagnosing obesity among different regions of China. However, there has been little studies about choosing effective obesity indicators in Han People of low-income Chinese adults in southwest China. The purpose of this study was to compare and evaluate the associations between different obesity indicators and cardiovascular disease risk factors (CVDRF) and choose the optimal cut-off values.A cross-sectional study was carried out in southwest of China, with multi-stage sampling enrolling 2112 subjects aged 20 to 80 years old. Anthropometric measurements included Body mass index (BMI), waist circumference (WC), Hip circumference, waist-to-hip ratio (WHR), and waist-to-height ratio (WHtR). We measured the percentage of body fat (PBF) by bioelectrical impedance analyzer to assess the body composition. The validity of different obesity indicators in assessing CVDRF risk were assessed through comparison area under curve of different indicators in assessing CVDRF risk in different gender. Logistic regression models were used to evaluate the association between the obesity indicators and CVDRF.When both male and female were considered, the optimal indicators were WHtR and percentage of body fat PBF for hypertension, WHR and WHtR for dyslipidemia. Both WC and WHtR were optimal indicators in assessing metabolic syndrome risk for both genders. When both disease and gender were considered, WHtR was the best associated indicators with various CVDRF. The cut-off of BMI and WC were consistent to the definition of obesity in Working Group of China. The WHtR positively correlated with the CVDRF. The cut-off of WHtR to do what was approximately 0.50 for adults in both genders in southwest of China.WHtR may be the best associated indicators for obesity-related CVDRF among the others (BMI, WC, Hip circumference, PBF, and WHR) in southwest of China. The cut-off of WHtR was approximately 0.50 for adults in both genders in southwest of China.

Characteristics of Harmonic Indexes of the Arterial Blood Pressure Waveform in Type 2 Diabetes Mellitus

Type 2 diabetes mellitus (T2DM) is an important public health issue worldwide. T2DM correlates with cardiovascular disease. Arterial stiffness is also a key factor that can be thought of as a surrogate marker. Nevertheless, it was unclear which harmonic indexes of blood pressure waveforms (BPWs) from subjects' radial artery pulses would be affected by T2DM. Therefore, the objective of this study was to investigate whether and how harmonic indexes can be used to discriminate hemodynamic differences between patients with T2DM and non-T2DM. This helps us to build objective results no matter who conducts the examination instead of pulse diagnosis in traditional way. We enrolled T2DM and non-T2DM patients as experimental and control groups, respectively, from the Department of Family Medicine in the National Taiwan University Hospital and the Department of Internal Medicine in Taipei's Veterans General Hospital from December 2017 to January 2019. ANSWatch® Model TS-0411 was used to capture the BPWs. Amplitude proportions (C_n values) were calculated from harmonics 1-10 of the BPW using fast Fourier transform. Thirty-two T2DM and 15 non-T2DM patients were enrolled. T2DM patients had significant differences in C₁ (p = 0.031) and C₅ (p = 0.041). The study suggests that analyzing the harmonic characteristics of non-invasively measured BPW of radial artery may be a potential and easy-to-perform approach to discriminate T2DM-induced hemodynamic changes.

The effects of rapid growth on body mass index and percent body fat: A meta-analysis

BACKGROUND & AIMS

Rapid growth in childhood and obesity are highly prevalent in congenital deficiency infants, but the associations between them remain controversial. This meta-analysis was performed to explore the effects of rapid growth on body mass index (BMI) and percent body fat (PBF), and to clarify potential confounders.

METHODS

A systematic search was performed using electronic databases including EMBASE (1985 to July 2019) and Medline (1966 to July 2019) for English articles. China National Knowledge Infrastructure Chinese citation database (CNKI) and WANFANG database were used to search articles in Chinese. Reference lists were also screened as supplement. All relevant studies that compare BMI or PBF between rapid group and control group were identified. The definition of rapid growth should be clearly specified. Means and standard deviations/95% confidence intervals (CIs) of BMI and PBF should be available. Relevant information was extracted independently by two reviewers. Study quality was reassessed using the Newcastle-Ottawa Scale. Publication bias and heterogeneity were detected. The random effect model was adopted for combined and stratified analysis.

RESULTS

About the effect of rapid growth on BMI, seventeen researches (4473 participants) involving 49 comparisons were included. Pooled analysis showed rapid group had higher BMI of 0.573 (95% CI, 0.355 to 0.791; P < 0.001). Stratified analyses revealed that catch-up weight gain, follow-up age >6 years old, rapid growth duration >2 years, full-term, comparing rapid growth SGA infants with control SGA infants, and from developed and developing countries, would all lead to higher BMI in rapid groups. About the effect of rapid growth on PBF, eleven researches (4594 participants) involving 37 comparisons were included. Pooled analysis showed rapid group had higher PBF of 2.005 (95% CI, 1.581 to 2.429; P < 0.001). Subgroup analyses suggested that catch-up weight gain, follow-up age ≤6 years old, rapid growth duration >2 years, full-term, comparing rapid growth SGA infants with control AGA infants, and participants from developing countries, would lead to increased PBF in rapid groups.

CONCLUSION

Rapid growth has a positive correlation with BMI and PBF. However, stratified analyses show that it is catch-up weight gain that lead to higher BMI and PBF, but not catch-up growth. In addition, rapid growth have long-term effect on BMI and short-term effect on PBF. Rapid growth duration longer than 2 years may increase the risk effect of rapid growth on BMI and PBF. But given that rapid growth would induce multiple health outcomes apart from BMI and PBF, the benefits and risks of rapid growth must be carefully considered and weighted.

High-risk multimorbidity patterns on the road to cardiovascular mortality

BACKGROUND

Multimorbidity, the co-occurrence of two or more diseases in one patient, is a frequent phenomenon. Understanding how different diseases condition each other over the lifetime of a patient could significantly contribute to personalised prevention efforts. However, most of our current knowledge on the long-term development of the health of patients (their disease trajectories) is either confined to narrow time spans or specific (sets of) diseases. Here, we aim to identify decisive events that potentially determine the future disease progression of patients.

METHODS

Health states of patients are described by algorithmically identified multimorbidity patterns (groups of included or excluded diseases) in a population-wide analysis of 9,000,000 patient histories of hospital diagnoses observed over 17 years. Over time, patients might acquire new diagnoses that change their health state; they describe a disease trajectory. We measure the age- and sex-specific risks for patients that they will acquire certain sets of diseases in the future depending on their current health state.

RESULTS

In the present analysis, the population is described by a set of 132 different multimorbidity patterns. For elderly patients, we find 3 groups of multimorbidity patterns associated with low (yearly in-hospital mortality of 0.2-0.3%), medium (0.3-1%) and high in-hospital mortality (2-11%). We identify combinations of diseases that significantly increase the risk to reach the high-mortality health states in later life. For instance, in men (women) aged 50-59 diagnosed with diabetes and hypertension, the risk for moving into the high-mortality region within 1 year is increased by the factor of 1.96 ± 0.11 (2.60 ± 0.18) compared with all patients of the same age and sex, respectively, and by the factor of 2.09 ± 0.12 (3.04 ± 0.18) if additionally diagnosed with metabolic disorders.

CONCLUSIONS

Our approach can be used both to forecast future disease burdens, as well as to identify the critical events in the careers of patients which strongly determine their disease progression, therefore constituting targets for efficient prevention measures. We show that the risk for cardiovascular diseases increases significantly more in females than in males when diagnosed with diabetes, hypertension and metabolic disorders.

Red Blood Cells Aggregation in the Patients with Type 2 Diabetes and T2D Associated Anemia, a Case Control Study in Bangladesh

Background and Aims: Type 2 Diabetes (T2D) is a chronic metabolic disorder. Nowadays the number of people with diabetes mellitus is quadrupling in the world as well as in Bangladesh. It is related to different types of disease morbidity and sociodemographic parameters. The present study aimed to investigate the association of RBC aggregation (measured by ESR level) with T2D and T2D associated anemia.

Material and method: A total of 234 subjects were included in the study. Sociodemographic and anthropometric information about study subjects were collected using a standard questionnaire. Blood samples were tested for random blood glucose levels, Hb percentage, and ESR. Association of these data with metabolic disorders was analyzed by statistical analysis software, SPSS.

Results: This study provides a piece of evidence that anemia is highly prevalent in T2D patients than the healthy control subjects in Bangladesh (59.1% vs 22.5%; P value <0.001). The ESR values were significantly elevated in T2D patients as well as anemic and aged subjects (P value <0.001).

Conclusion: The study thus suggests that anemia was prevalent in T2D patients in Bangladesh. The RBC aggregation was significantly elevated in patients with T2D as well as anemia, indicating increased inflammatory response in these diseases.

Analysis of factors related to diabetic retinopathy in patients with newly diagnosed type 2 diabetes: a cross-sectional study

AIM

To investigate the related factors of diabetic retinopathy (DR) and explore the correlation between smoking and DR in patients with newly diagnosed type 2 diabetes mellitus (T2DM).

DESIGN

A single-centre cross-sectional study.

SETTING

Tianjin 4th Central Hospital.

PARTICIPANTS

Patients with newly diagnosed T2DM who visited the outpatient department of the hospital from December 2018 to April 2019.

METHODS

A total of 947 patients were enrolled in the study. They were divided into two groups according to whether they were diagnosed with DR (diabetic retinopathy group, DR group; non-diabetic retinopathy group, NDR group). The smoking index (SI) was calculated to assess smoking status. Factors such as sex, age, hypertension, T2DM diagnosed age, family history of diabetes, drinking history, haemoglobin A1c (HbA1c), body mass index (BMI) and smoking status were compared between the two groups. Logistic regression was used to analyse the relationship between DR and the above factors.

RESULTS

There was no statistically significant difference between the two groups in sex, age, hypertension, DM diagnosed age, family history of diabetes, drinking history and HbA1c. BMI was significantly higher in DR patients (27.7±4.2 vs 26.7±4.4, p=0.004). Smoking status was also different between the two groups (χ²=6.350, p=0.042). BMI was shown to be a related factor for DR in patients with newly diagnosed diabetes (OR=0.592, p=0.004). When BMI was ≥28 kg/m², heavy smoking was significantly associated with DR (OR=2.219, p=0.049), and there was a negative correlation between DR and the age of diagnosis of diabetes ≥60 years (OR=0.289, p=0.009).

CONCLUSIONS

Heavy smoking was an important related factor for DR in patients with newly diagnosed diabetes mellitus when BMI was ≥28 kg/m². Delaying the age of diabetes might prevent the occurrence of DR. To elucidate the correlation, long-term cohort studies with large samples are needed.

The Relationship Between Baseball Participation and Health: A Systematic Scoping Review

OBJECTIVE

To investigate the relationship between baseball participation and health (musculoskeletal, general, and psychological health) and to identify research gaps in the existing literature.

DESIGN

Systematic scoping review.

LITERATURE SEARCH

Medical databases and gray literature were systematically searched from inception to November 2018.

STUDY SELECTION CRITERIA

All studies that investigated constructs related to the health of current or former baseball players were included.

DATA SYNTHESIS

Data were extracted for thematic summaries.

RESULTS

Ten thousand five hundred seventy-four titles/abstracts were screened, and 678 studies were included. Ninety percent of articles included only baseball players playing in the United States, 34% of articles investigated professional baseball players, and 11% studied college baseball players. Five hundred eighty-three (86%) studies investigated musculoskeletal health, 77 (11%) general health, and 18 (3%) psychological health. Injury incidence (injuries per 1000 athlete exposures) ranged from 0.7 to 3.6 in professional, 4.7 to 5.8 in college, and 0.8 to 4.0 in high school baseball. Among baseball players, 31% to 50% reported regular tobacco use. There was limited research investigating psychological health in current or former baseball players at all competition levels.

CONCLUSION

Almost 90% of all articles investigated musculoskeletal health, with few articles studying general or psychological health. Baseball players have high tobacco, alcohol, and drug use compared to the general population, which may have negative health outcomes. Little is understood about the long-term musculoskeletal, general, and psychological health of baseball players. J Orthop Sports Phys Ther 2020;50(2):55-66. doi:10.2519/jospt.2020.9281.

Association of Diabetes Mellitus and Biomarkers of Abnormal Glucose Metabolism With Incident Radiographic Knee Osteoarthritis

OBJECTIVE

The association of diabetes mellitus (DM) with increased risk of knee osteoarthritis (OA) is uncertain. We evaluated associations of DM and biomarkers of abnormal glucose metabolism with incident radiographic knee OA, controlling for body mass index (BMI).

METHODS

Participants (mean ± SD age 60.6 ± 7.8 years; mean ± SD body mass index [BMI] 29.1 ± 4.9 kg/m2 ) were from the Multicenter Osteoarthritis Study and did not have radiographic knee OA at baseline (Kellgren/Lawrence [K/L] grade <2 bilaterally). A random sample (n = 987) was selected and stratified by BMI. Baseline serum fasting glucose and homeostasis model assessment-estimated insulin resistance (HOMA-IR) were measured. Participants were categorized as having DM based on self-report, use of medication, or fasting glucose ≥126 mg/dl. Incident radiographic knee OA (K/L grade ≥2 or knee replacement) was assessed at 3 follow-up visits (30, 60, and 84 months). Knee-level pooled logistic regression analysis was performed to obtain odds ratios (ORs) (95% confidence interval [95% CI]) for associations of DM status and biomarkers of abnormal glucose metabolism with incident radiographic knee OA.

RESULTS

After adjustment for BMI, the odds of incident radiographic knee OA were not associated with baseline DM status nor with levels of fasting glucose and HOMA-IR, overall and in men. In women, HOMA-IR was inversely associated with odds of incident radiographic knee OA (adjusted OR 0.80 [95% CI 0.69-0.94], P = 0.005).

CONCLUSION

DM and higher levels of biomarkers of abnormal glucose metabolism were not associated with increased odds of incident radiographic knee OA after adjusting for BMI in this cohort overall. A possible protective association of higher HOMA-IR with incident radiographic knee OA in women warrants further investigation.

Ultra-performance liquid chromatography-mass spectrometry-based metabolomics reveals Huangqiliuyi decoction attenuates abnormal metabolism as a novel therapeutic opportunity for type 2 diabetes

Background: As a typical chronic metabolic disease, type 2 diabetes mellitus causes a heavy health-care burden to society. In this study, we applied the metabolomics strategy to explore the potential molecular mechanism of the Huangqiliuyi decoction (HQLYD) for type-2 diabetes (T2D). Ultra-performance liquid chromatography-mass spectrometry (UPLC-MS) combined with pattern recognition methods was utilized to select specific metabolites closely associated with HQLYD. Biomarker pathway analysis and biological network were utilized to uncover the therapeutic effect and action mechanism related to HQLYD. A total of twenty-five biomarkers were identified in the animal model, in which sixteen biomarkers are associated with HQLYD treatment for T2D. They attenuated the abnormalities of metabolic pathways such as phenylalanine, tyrosine and tryptophan biosynthesis, phenylalanine metabolism, and the citrate cycle. HQLYD also significantly elevated the serum FINS and SOD, GSP-x level in the liver and kidney, and reduced the serum TC, TG, HDL, LDL, urea, Scr, AST, ALT, FBG, IRS, MDA, and CAT level. We found that the therapeutic mechanism of HQLYD against T2D affected amino acid metabolism, glucose metabolism and lipid metabolism. Metabolomics revealed that the Huangqiliuyi decoction attenuates abnormal metabolism as a novel therapeutic opportunity for type 2 diabetes.

Associations between circulating inflammatory markers, diabetes type and complications in youth

BACKGROUND

Inflammation is implicated in the pathogenesis of diabetes and its complications in adults. Little is known about the relative contribution of inflammation in common types of diabetes in youth: type 1 diabetes (T1D), type 2 diabetes (T2D), and cystic fibrosis-related diabetes (CFRD). This study investigates inflammatory markers by diabetes type and complication status, and assesses indicators of inflammation and complications.

METHODS

A cross-sectional study of 134 T1D, 32 T2D, 32 CFRD and 48 subjects without diabetes (including 11 with CF and normal glucose tolerance) was undertaken. Inflammation was assessed by sE-selectin by ELISA, hsCRP by turbidimetry, WCC and ESR. Nephropathy was defined by albuminuria, autonomic neuropathy by heart rate variability, and peripheral neuropathy by vibration and thermal threshold testing and retinopathy by seven-field stereoscopic fundus photography. Descriptive statistics, parametric and non-parametric ANOVA and regression analyses were performed, with significance at P < .05.

RESULTS

Of 198 diabetic participants; 49% female, mean (SD) age, median diabetes duration and median HbA1c were 16 (2.5) and 6 (3-9) years, and 8.1 (6.9-9.3)%, respectively. All inflammatory markers were lower in T1D than in other diabetes groups (P < .05) but higher than in non-diabetic controls. T2D (n = 32) and CFRD (n = 32) subjects had comparable elevated levels of inflammation. Body mass index (BMI) was a strong independent explanatory variable of inflammation. In multivariate analysis, hsCRP and ESR were associated with complications in addition to HbA1c, BMI, and diastolic BP.

CONCLUSIONS

Circulating inflammatory markers are elevated in adolescents with diabetes, being higher and comparable in T2D and CFRD than in T1D. Inflammation is independently associated with diabetes complications, consistent with inflammation driving vascular pathology in diabetes.

[Short-term intensive combined therapy with metformin, sagliptin and dapagliflozin for newly diagnosed type 2 diabetes: efficacy, weight control and safety]

OBJECTIVE

To assess the efficacy and safety of short- term intensive hypoglycemic therapy with a triple regimen consisting of metformin, sagliptin and dapagliflozin in patients with newly diagnosed type 2 diabetes mellitus with hemoglobin Alc (HbA1c) of 9%-12%.

METHODS

We prospectively enrolled 58 patients with newly diagnosed type 2 diabetes, who were treated with metformin combined with sagliptin and dapagliflozin for 12 weeks on the basis of diabetic diet and regular exercise. Blood glucose was monitored during the treatment and the changes in HbA1c, fasting blood glucose (FBG), 2-hour postprandial blood glucose (2 hPBG), fasting insulin (FINS), 2-hour postprandial insulin (2 hPINS), fasting C-peptide (F-CP), 2-hour postprandial C-peptide (2 hP-CP), and body weight after treatment as well as the incidence of hypoglycemia and adverse events associated with the treatment were recorded.

RESULTS

Two patients withdrew from the study for intolerance of gastrointestinal reactions, and another 2 withdrew for inconvenience of access to the medicines. Fifty-four of the patients finally completed the study, including 34 male and 20 female patients. After 12 weeks of therapy, all the patients showed significant improvements in FBG, 2 hPBG, HbA1c, HOMA-beta and HOMA-IR (P < 0.001) with a mean reduction of HbA1c level by (4.19 ± 1.07)%, and the goal of HbA1c control to below 7.0% was achieved in 83.33% of the patients. The reduction of HbA1c was correlated with FBG (r=0.487, P=0.000), 2 hPBG (r=0.310, P=0.023), and HOMA-β (r=-0.398, P=0.003). The patients had a mean body weight loss by 2.47±3.38 kg (P < 0.001) and a mean decrease of body mass index (BMI) by 0.90± 1.18 kg/m2 (P < 0.001) after the therapy. The body weight-reducing effect was associated with the patients' baseline body weight (r=0.678, P=0.000), BMI (r=0.818, P=0.000), F-CP (r=0.282, P=0.039) and HOMA-IR (r=0.297, P=0.029). During the therapy 8 patients experienced hypoglycemic symptoms (10 times, 14.81%); 3 patients were diagnosed with hypoglycemia (blood glucose ≤3.9 mmol/L, 3 times), and the overall incidence of hypoglycemia was 5.56%. No serious hypoglycemia or infections of the urinary and reproductive systems occurred in these patients.

CONCLUSIONS

Short-term intensive oral hypoglycemic therapy with metformin combined with sagliptin and dapagliflozin is effective for treatment of patients with newly diagnosed type 2 diabetes with HbA1c of 9%-12% and shows a good weight-reducing effect with a low risk of hypoglycemia. The combined therapy can effectively improve β-cell insulin secretion function, and is suitable for treatment of newly diagnosed type 2 diabetic patients with high blood glucose.

Association of serum total fatty acids with type 2 diabetes

BACKGROUND

Type 2 diabetes (T2D), a typical metabolic disease, is closely associated with serum free fatty acids. But the association between serum total fatty acids (TFAs, free fatty acids plus esterified fatty acids) and T2D has not been reported.

METHODS

Serum esterified fatty acids were hydrolyzed under alkaline conditions, and serum TFAs were extracted after acidizing. Fourteen of serum TFAs in 1,828 serum samples, including 543 controls, 655 prediabetes, and 630 T2D patients, were simultaneously quantified based on the calibration curves of 8 fatty acids using matrix-assisted laser desorption/ionization-Fourier transform ion cyclotron resonance mass spectrometry (MALDI-FTICR MS).

RESULTS

Correlation analysis revealed strong correlations among serum TFAs and ratios of the TFAs in T2D patients compared with controls or prediabetes both in males and females. Receiver operating characteristic analysis indicated that a panel including fasting plasma glucose, glycosylated hemoglobin type A1c, gamma-glutamyltransferase, triglyceride, C18:1, and C20:3, has a good capability to distinguish prediabetes from T2D, with the sensitivity of 87.0%, the specificity of 91.0%, and the area under curve (AUC) of 0.96.

CONCLUSIONS

In this study, rapid, absolute, and simultaneous quantification of serum TFAs was performed using MALDI-FTICR MS. C18:1 and C20:3 were significantly correlated with prediabetes and T2D.

Lower body mass index is not of more benefit for diabetic complications

AIMS/INTRODUCTION

To investigate the relationship between different body mass index (BMI) levels and vascular complications in type 2 diabetes mellitus patients.

MATERIALS AND METHODS

Data were collected from 3,224 individuals with type 2 diabetes mellitus (male/female: 1,635/1,589; age 61.31 ± 11.45 years), using a retrospective case study design. The association of BMI quintiles and diabetes mellitus vascular complications was assessed using multiple logistic regression models adjusting for age, sex, diabetes duration, smoking status, drinking and other confounders, using those with the lowest quintile of BMI as the reference group.

RESULTS

With increasing BMI, the detection rate of diabetic peripheral neuropathy and peripheral arterial disease initially decreased and then it increased, whereas the detection rate of diabetic kidney disease and carotid atherosclerotic plaques showed an upward trend; however, diabetic retinopathy was irregular. The odds ratios of diabetic peripheral neuropathy decreased as BMI increased from the 21st percentile to the 80th percentile initially, and increased when BMI was in >80th percentile. The same result was shown in peripheral arterial disease. BMI >80th percentile showed a 1.426-fold risk of diabetic kidney disease and a 1.336 -fold risk of carotid atherosclerotic plaque.

CONCLUSIONS

In patients with type 2 diabetes mellitus, the relationship between different BMIs and vascular complications varies. A U-shaped relationship was observed between BMI and diabetic peripheral neuropathy, as well as BMI and peripheral arterial disease. BMI is positively correlated with diabetic kidney disease and carotid atherosclerotic plaque; however, it is not correlated with diabetic retinopathy.

Impact of body mass index on the efficacy and safety of ipragliflozin in Japanese patients with type 2 diabetes mellitus: A subgroup analysis of 3-month interim results from the Specified Drug Use Results Survey of Ipragliflozin Treatment in Type 2 Diabetic Patients: Long-term Use study

AIMS/INTRODUCTION

Specified Drug Use Results Survey of Ipragliflozin Treatment in Type 2 Diabetic Patients: Long-term Use is an ongoing postmarketing study of ipragliflozin for long-term use in Japanese patients with type 2 diabetes mellitus. A subgroup analysis of data from the study was carried out to investigate the impact of obesity on the efficacy and safety of ipragliflozin in this population.

MATERIALS AND METHODS

Patients were divided into the following subgroups according to their body mass index (BMI): <22.0, 22.0 to <25.0, 25.0 to <30.0 and ≥30.0 kg/m2 . Changes in bodyweight and glycemic parameters up to 3 months were evaluated, as well as adverse drug reactions (ADRs) that occurred during ipragliflozin treatment.

RESULTS

In the efficacy analysis set (8,633 patients), glycemic control and bodyweight statistically significantly improved from baseline to 3 months in all BMI subgroups (all P < 0.05). No strong correlations were identified between changes in bodyweight and changes in hemoglobin A1c, waist circumference or BMI in any of the subgroups. The incidence of adverse drug reactions was 6.29, 8.44, 11.18 and 11.74% in the <22.0, 22.0 to <25.0, 25.0 to <30.0 and ≥30.0 kg/m2 groups, respectively (P = 0.001), in the safety analysis set (n = 11,053 patients).

CONCLUSIONS

In Japanese patients with type 2 diabetes mellitus, ipragliflozin improved glycemic control and reduced bodyweight, regardless of BMI. Adverse drug reactions were more common in patients with higher BMI than in those with lower BMI.

The Real Happy Study: Protocol for a Prospective Assessment of the Real-World Effectiveness of the HAPIFED Program-a Healthy APproach to weIght management and Food in Eating Disorders

The prevalence of obesity with comorbid binge eating behaviour is growing at a faster rate than that seen for either obesity or eating disorders as separate conditions. Approximately 6% of the population are affected and they potentially face a lifetime of poor physical and mental health outcomes and an inability to sustain long-term weight loss. Current treatment options are inadequate in that they typically address either obesity or eating disorders exclusively, not the combination of both conditions. By treating one condition without treating the other, relapse is common, and patients are often left disappointed with their lack of weight loss. An integrated approach to treating these individuals is needed to prevent a worsening of the comorbidities associated with excess body weight and eating disorders. A new therapy has recently been developed, named HAPIFED, which addresses both overweight/obesity and comorbid binge eating behaviour with the combination of behavioural weight loss therapy and cognitive behaviour therapy-enhanced (CBT-E). The aim of this paper is to document the protocol for the Real Happy Study, which will evaluate the effectiveness of the HAPIFED program in treating overweight or obesity with comorbid binge-eating behaviour in a real-world setting.

Olfactory Dysfunction Mediates Adiposity in Cognitive Impairment of Type 2 Diabetes: Insights From Clinical and Functional Neuroimaging Studies

OBJECTIVE

Large numbers of people with type 2 diabetes are obese. However, changes in cognition and related brain function in obese people with diabetes have not been characterized. Here, we investigated cognition, olfactory function, and odor-induced brain alterations in these patients and therapeutic effects of glucagon-like peptide 1 receptor agonists (GLP-1Ras) on their psychological behavior and olfactory networks.

RESEARCH DESIGN AND METHODS

Cognitive, olfactory, and odor-induced brain activation assessments were administered to 35 obese and 35 nonobese people with type 2 diabetes and 35 control subjects matched for age, sex, and education. Among them, 20 obese individuals with diabetes with inadequate glycemic control and metformin monotherapy received GLP-1Ra treatment for 3 months and were reassessed for metabolic, cognitive, olfactory, and neuroimaging changes.

RESULTS

Obese subjects with diabetes demonstrated lower general cognition and olfactory threshold scores, decreased left hippocampal activation, and disrupted seed-based functional connectivity with right insula compared with nonobese subjects with diabetes. Negative associations were found between adiposity and episodic memory and between fasting insulin and processing speed test time in diabetes. Mediation analyses showed that olfactory function and left hippocampus activation mediated these correlations. With 3-month GLP-1Ra treatment, obese subjects with diabetes exhibited improved Montreal Cognitive Assessment (MoCA) score, olfactory test total score, and enhanced odor-induced right parahippocampus activation.

CONCLUSIONS

Obese subjects with type 2 diabetes showed impaired cognition and dysfunctional olfaction and brain networks, the latter of which mediated adiposity in cognitive impairment of diabetes. GLP-1Ras ameliorated cognitive and olfactory abnormalities in obese subjects with diabetes, providing new perspectives for early diagnosis and therapeutic approaches for cognitive decrements in these patients.

Life satisfaction and other determinants of eating behaviours among women aged 40-65 years with type 2 diabetes from the Krakow population

Introduction

A rational dietary model is one of the key aspects in the treatment of type 2 diabetes.

Aim of the study

The study aimed to analyse the frequency of consuming selected groups of food products among women aged 40-65 years with type 2 diabetes, depending on age, BMI, duration of disease, and level of life satisfaction.

Material and methods

The study was carried out among 276 women using the author’s specially designed questionnaire (metric data, duration of diabetes) and the Satisfaction with Life Scale (SWLS). We assessed BMI values on the basis of measurements of somatic indicators (body mass and height). Statistical analysis was performed using Pearson’s r and Spearman’s R correlation coefficients via the SPSS programme (significance level of α = 0.05).

Results

Among the women with type 2 diabetes we observed nutritional deficiencies, in particular a low frequency of consuming the recommended product groups (vegetables, fruit, legume seeds, whole-grain cereals, dairy products with reduced fat content, and nuts). The scale of rational dietary choices among women increased along with age and perceived life satisfaction. As the time from diagnosis passed, this scale decreased. A decrease was also noted along with the increase in BMI.

Conclusions

The frequency of consuming some product groups shows a significant relationship with age, BMI, duration of disease, and the level of life satisfaction among women aged 40-65 years with type 2 diabetes.

Association between type 1 and type 2 diabetes and risk of non-Hodgkin's lymphoma: A meta-analysis of cohort studies

AIM

Diabetes mellitus (DM) is thought to be associated with an increased risk of non-Hodgkin's lymphoma (NHL), although the evidence so far remains inconsistent. Thus, our study aimed to further assess this association.

METHODS

Electronic searches were performed of the PubMed, Web of Science and Embase databases up to 11 March 2019. A random-effects model was used to calculate summary relative risks (RRs) with corresponding 95% confidence intervals (CIs).

RESULTS

A total of 20 articles including data from 35 cohort studies matched our inclusion criteria, and 31 RRs were calculated for type 2 DM; the summary RR was 1.20 (95% CI: 1.12-1.30, I² = 84.7%). Also, four RRs were calculated for type 1 DM, and the result was significant (RR: 1.55, 95% CI: 1.15-2.08, I² = 0.0%). The results of subgroup analyses demonstrated that the association between DM and NHL was much more substantial in an Asian population, while sensitivity analyses suggested the robustness of a positive association between DM and NHL risk. In addition, the RR of NHL correlated negatively with duration of DM, with the highest risk found in patients within 1-2 years of DM diagnosis.

CONCLUSION

Our study findings suggest a moderate increase in risk of NHL in type 1 and 2 DM patients. Future studies should investigate the effects of duration of DM and antidiabetes interventions on NHL risk.

Relationship between Body Mass Index and T-Scores of Bone Mineral Density in the Hip and Spine Regions among Older Adults with Diabetes: A Retrospective Review

Diabetes mellitus (DM) cases are increasing worldwide, especially in Saudi Arabia. Previous studies suggested a positive relationship between body mass index (BMI) and bone mineral density (BMD) levels. Generally, patients with low BMI (<18.5 kg/m2) have reduced BMD levels and, thus, low T-scores; hence, they are categorized as osteopenic or osteoporotic. In this study, we aimed to determine whether a relationship between BMI and BMD T-scores in the hip and spine regions of patients with diabetes exists. This retrospective record review investigated older adult patients with diabetes in King Abdulaziz University Hospital (n=198; age 50-90 years) who underwent BMD scan between January 1, 2016, and June 25, 2018, regardless of their sex but limited to type 2 DM. The height and weight of all subjects were recorded, and BMI was calculated and categorized. We used SPSS version 21 for data analysis; measures of central tendencies, Pearson's correlations, chi-square tests, and independent t-tests were employed. We found positive relationships between BMI and BMD T-scores in the hip and spine regions (right femoral neck: R=+0.214, P ≤ 0.002; total right hip: R=+0.912, P ≤ 0.001; left femoral neck: R=+0.939, P ≤ 0.001; total left hip: R=+0.885, P ≤ 0.001; and total lumbar region: R=+0.607, P ≤ 0.001). Low BMI (<18.5 kg/m2) could be a risk factor for osteoporosis, whereas normal/high BMI could be protective against osteoporosis among adults with diabetes.

Association between full monitoring of biomedical and lifestyle target indicators and HbA1c level in primary type 2 diabetes care: an observational cohort study (ELZHA-cohort 1)

OBJECTIVE

Management of type 2 diabetes mellitus (T2DM) requires frequent monitoring of patients. Within a collective care group setting, doubts on the clinical effects of registration are a barrier for full adoption of T2DM registration in general practice. We explored whether full monitoring of biomedical and lifestyle-related target indicators within a care group approach is associated with lower HbA_1c levels.

DESIGN

Observational, real-life cohort study.

SETTING

Primary care data registry from the Hadoks (EerstelijnsZorggroepHaaglanden) care group.

EXPOSURE

The care group provides general practitioners collectively with organisational support to facilitate structured T2DM primary care. Patients are offered quarterly medical and lifestyle-related consultation.

MAIN OUTCOME MEASURE

Full monitoring of each target indicator in patients with T2DM which includes minimally one measure of HbA_1c level, systolic blood pressure, LDL, BMI, smoking behaviour and physical exercise between January and December 2014; otherwise, patients were defined as 'incompletely monitored'. HbA_1c levels of 8137 fully monitored and 3958 incompletely monitored patients were compared, adjusted for the confounders diabetes duration, age and gender. Since recommended HbA_1c values depend on age, medication use and diabetes duration, analyses were stratified into three HbA_1c profile groups. Linear multilevel analyses enabled adjustment for general practice.

RESULTS

Compared with incompletely monitored patients, fully monitored patients had significantly lower HbA_1c levels (95% CI) in the first (-2.03 [-2.53 to -1.52] mmol/mol) (-0.19% [-0.23% to -0.14%]), second (-3.36 [-5.28 to -1.43] mmol/mol) (-0.31% [-0.48% to -0.13%]) and third HbA_1c profile group (-1.89 [-3.76 to -0.01] mmol/mol) (-0.17% [-0.34% to 0.00%]).

CONCLUSIONS/INTERPRETATION

This study shows that in a care group setting, fully monitored patients had significantly lower HbA_1c levels compared with incompletely monitored patients. Since this difference might have considerable clinical impact in terms of T2DM-related risks, this might help general practices in care group settings to overcome barriers on adequate registration and thus improve structured T2DM primary care. From population health management perspective, we recommend a systematic approach to adjust the structured care protocol for incompletely monitored subgroups.

Risk prediction for breast Cancer in Han Chinese women based on a cause-specific Hazard model

Background

Considering the lack of efficient breast cancer prediction models suitable for general population screening in China. We aimed to develop a risk prediction model to identify high-risk populations, to help with primary prevention of breast cancer among Han Chinese women.

Methods

A cause-specific competing risk model was used to develop the Han Chinese Breast Cancer Prediction model. Data from the Shandong Case-Control Study (328 cases and 656 controls) and Taixing Prospective Cohort Study (13,176 participants) were used to develop and validate the model. The expected/observed (E/O) ratio and C-statistic were calculated to evaluate calibration and discriminative accuracy of the model, respectively.

Results

Compared with the reference level, the relative risks (RRs) for highest level of number of abortions, age at first live birth, history of benign breast disease, body mass index (BMI), family history of breast cancer, and life satisfaction scores were 6.3, 3.6, 4.3, 1.9, 3.3, 2.4, respectively. The model showed good calibration and discriminatory accuracy with an E/O ratio of 1.03 and C-statistic of 0.64.

Conclusions

We developed a risk prediction model including fertility status and relevant disease history, as well as other modifiable risk factors. The model demonstrated good calibration and discrimination ability.

Differences in nutritional status and activities of daily living and mobility in elderly hospitalized patients with heart failure

Aims

This study aims to examine the effect of differences in nutritional status on activities of daily living (ADL) and mobility recovery of hospitalized elderly patients with heart failure (HF).

Methods and results

From among 377 consecutive HF patients who underwent rehabilitation at one acute‐care hospital from January 2013 to August 2015, those who were aged ≥ 65 years could walk with assistance before hospitalization and who were hospitalized for the first time were included in this retrospective cohort study. Exclusion criteria were pacemaker surgery during hospitalization, change to other departments, death during hospitalization, and unmeasured ADL. We investigated patient characteristics, basic attributes, Geriatric Nutritional Risk Index (GNRI), ADL [motor Functional Independence Measure (motor FIM)], and Rivermead Mobility Index (RMI). Of these 377 patients, 96 met the inclusion criteria and were divided into the low GNRI group (n = 38, 83.5 ± 8.3 years, 44.7% male) and high GNRI group (n = 58, 81.0 ± 6.6 years, 55.2%). Patient characteristics and the difference between motor ADL and motility recovery and nutrition data were analysed with unpaired t‐test, χ² test, and two‐way analysis of covariance. In comparing the two groups, the following parameters were significantly lower in the low GNRI group than in the high GNRI group: body mass index (18.7 ± 2.2 vs. 23.2 ± 2.7 kg/m², P < 0.01), albumin (3.4 ± 0.4 vs. 3.8 ± 0.4 g/dL, P < 0.01), diabetes mellitus ratio (21.1% vs. 50.0%, P < 0.01), RMI at discharge (6.8 ± 2.6 vs. 8.2 ± 2.2, P = 0.01), and motor FIM at discharge (67.2 ± 19.5 vs. 75.6 ± 13.3, P = 0.02). RMI showed a significant group and term main effect and interaction effect (P < 0.05). Motor FIM showed a significant main effect of group and term (P < 0.05), and no significant interaction effect.

Conclusions

Low nutritional status in hospitalized elderly HF patients affected their recovery of mobility but did not appear to affect the recovery of ADL.

Evaluation of Angiotensinogen M235T and T174M Polymorphisms, Demographic and Clinical Factors in New-Onset Diabetes after Liver Transplantation in Iranian Patients

BACKGROUND

New-onset diabetes after transplantation (NODAT) is a serious complication which runs the risk of infections, morbidity and mortality.

OBJECTIVE

To evaluate M235T and T174M polymorphisms of angiotensinogen gene along with some demographic and clinical factors including age; sex; body mass index (BMI); model for end-stage liver disease (MELD) score; prednisolone, mycophenolate mofetil and tacrolimus dose; and serum level in NODAT among liver recipients.

METHODS

In this study 115 patients (53 with and 62 without NODAT) who had no history of diabetes before the transplantation were investigated. Furthermore, 80 randomly selected apparently healthy people (no transplantation) were used as the control group. Two angiotensinogen polymorphisms (M235T and T174M) were studied using polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP).

RESULTS

Patients included 68 (59.1%) females and 47 (40.9%) males; they had a mean±SD age of 37.4±16.9 years. The M allele frequency was 55.7% (n=128) in M235T and 20.0% (n=46) in T174M polymorphisms. Binary logistic regression analysis confirmed that age (p=0.005), prednisolone dose (p<0.001) and mutated M235T polymorphism (p=0.003) were independent risk factors.

CONCLUSION

Presence of M235T T allele may significantly (p<0.001) increase the NODAT risk, and increase the likelihood of developing end-stage liver disease (p=0.003). T174M T allele had a significantly (p=0.007) higher frequency in NODAT group.

Estimating transition probability of different states of type 2 diabetes and its associated factors using Markov model

AIMS

Type 2 diabetes is a chronic metabolic disorder and one of the most common non-contagious diseases which is on the rise all over the world. The present study aims to assess the trend of change in fasting blood sugar (FBS) and factors associated with the progression and regression of type 2 diabetes. Moreover, this study estimates transition intensities and transition probabilities among various states using the multi-state Markov model.

METHODS

In this study Multi-Ethnic Study of Atherosclerosis (MESA) dataset, from a longitudinal study, was used. The study, at the beginning, included 6814 individuals who were followed during the five phases of the study. FBS, serving as the criterion to assess the progression of diabetes, was classified into four states including (a) normal (FBS<100mg/dl), (b) impaired fasting glucose I (IFG I) (100mg/dl<FBS<110mg/dl), (c) impaired fasting glucose II (IFG II) (110mg/dl<FBS<126mg/dl), and (d) diabetes status (FBS>126mg/dl). A continuous-time Markov process was used to describe the evaluation of disease changes over the four states. The model estimated the mean sojourn time for each state.

RESULTS

Based on the results obtained from fitting the Markov model, the transition probability for a normal individual to remain in the same status over a 10-year period was 0.63, while the probability for a person in the diabetes state was 0.40. The mean sojourn time for the normal and diabetic individuals aged 45-84 years was 6.26 and 5.20 respectively. The covariates of age, race, body mass index (BMI), physical activity, waist-to-hip ratio (WHR) and blood pressure, significantly affected the progression and regression of diabetes.

CONCLUSION

An increase in physical activity could be the most important factor in the regression of diabetes, while an increase in WHR and BMI could be the most significant factors in progression of the disease.

Effectiveness of motivational interviewing for improving physical activity self-management for adults with type 2 diabetes: A review

Objectives This review examines the effectiveness of motivational interviewing for physical activity self-management for adults diagnosed with diabetes mellitus type 2. Motivational interviewing is a patient centered individually tailored counseling intervention that aims to elicit a patient's own motivation for health behavior change. Review questions include (a) How have motivational interviewing methods been applied to physical activity interventions for adults with diabetes mellitus type 2? (b) What motivational interviewing approaches are associated with successful physical activity outcomes with diabetes mellitus 2? Methods Database searches used PubMed, CINAHL, and PsycINFO for the years 2000 to 2016. Criteria for inclusion was motivational interviewing used as the principal intervention in the tradition of Miller and Rollnick, measurement of physical activity, statistical significance reported for physical activity outcomes, quantitative research, and articles written in English. Results A total of nine studies met review criteria and four included motivational interviewing interventions associated with significant physical activity outcomes. Discussion Findings suggest motivational interviewing sessions should target a minimal number of self-management behaviors, be delivered by counselors proficient in motivational interviewing, and use motivational interviewing protocols with an emphasis placed either on duration or frequency of sessions.

Supporting Transitions in Care for Older Adults With Type 2 Diabetes Mellitus and Obesity

The aim of the current study was to compare outcomes for older adults with type 2 diabetes mellitus and obesity following participation in a transitional care intervention that included diabetes self-management education (DSME) and homecare. The three groups analyzed comprised an inpatient DSME plus homecare group (n = 35); an inpatient DSME only group (n = 100); and a group who received usual care (n = 45). Outcomes of interest included rehospitalization rates and hemoglobin A1C (A1C) for up to 1-year post hospital discharge. Rates of rehospitalization and A1C improved for older adults who received nurse-led inpatient DSME and homecare during transitions of care from hospital to home. Rehospitalization rates up to 90 days were decreased for the DSME plus homecare group (10%) compared to DSME only (20%) and usual care groups (26.7%) (p < 0.05). A decrease of -0.4 and -2.3 A1C units was observed for the DSME group and DSME plus homecare group, respectively, at 90 days. These results support a transitional care educational intervention for older adults with type 2 diabetes mellitus and obesity.

TARGETS

Older adults with type 2 diabetes mellitus and obesity.

INTERVENTION DESCRIPTION

Transitional care intervention including diabetes self-management education and homecare.

MECHANISMS OF ACTION

Inpatient diabetes education and homecare helps improve rates of rehospitalization and hemoglobin A1C during care transitions from hospital to home.

OUTCOMES

Rehospitalization rates, glycemic control (i.e., A1C level). [Res Gerontol Nurs. 2018; 11(2):71-81.].

High-intensity interval training versus continuous training on physiological and metabolic variables in prediabetes and type 2 diabetes: A meta-analysis

AIMS

To compare the effects of high-intensity interval training (HIIT) versus moderate-intensity continuous training (MICT) on functional capacity and cardiometabolic markers in individuals prediabetes and type 2 diabetes (T2D).

METHODS

The search was performed in PubMed (MEDLINE), EMBASE, PEDro, CENTRAL, Scopus, LILACS database, and Clinical Trials from the inception to July 2017, included randomized clinical trials that compared the use of HIIT and MICT in prediabetes and T2D adults. The risk of bias was defined by Cochrane Handbook and quality of evidence by GRADE.

RESULTS

From 818 relevant records, seven studies were included in systematic review (64 prediabetes and 120 T2D patients) and five with T2D were meta-analyzed. HIIT promoted significantly increased of 3.02 mL/kg/min (CI95% 1.42-4.61) of VO₂max, measured for functional capacity, compared to MICT. No differences were found between two modalities of exercises considering the outcomes HbA1c, systolic and diastolic blood pressure, total cholesterol, HDL and LDL cholesterol, triglycerides, BMI, and waist-to-hip ratio. Most of the studies presented unclear risk of bias, and low and very low quality of evidence.

CONCLUSION

HIIT induces cardiometabolic adaptations similar to those of MICT in prediabetes and T2D, and provides greater benefits to functional capacity in patients with T2D.

Newer GLP-1 receptor agonists and obesity-diabetes

Obesity is a major risk factor for type 2 diabetes and may complicate type 1 diabetes. In parallel with the global epidemic of obesity, the incidence of type 2 diabetes is increasing exponentially. To reverse these alarming trends, weight loss becomes a major therapeutic priority in prevention and treatment of type 2 diabetes. Given that glucagon-like peptide-1 receptor agonists (GLP-1 RAs) improve glycaemic control and cause weight loss, they are receiving increasing attention for the treatment of diabetes-obesity. This review discusses current and emerging therapeutic options with GLP-1 RAs and considers the next generation of novel peptide co-agonists with the potential for improved therapeutic outcomes in obesity and type 2 diabetes.

Prevalence of diabetes type 2 in older adults: Findings from a large population-based survey in Tehran, Iran (Urban HEART-2)

AIMS

Diabetes is a common problem in older adults, as they increasingly comprise a larger proportion of patients newly diagnosed with diabetes. The evidence on the prevalence and distribution of type 2 diabetes (DT2) and its related factors among older adults in Iran is sparse. The aim of the present study was to determine the prevalence of DT2 among Iranian older adults aged ≥60years.

MATERIALS AND METHODS

The study was part of a comprehensive survey (Urban HEART-2) which was a large population-based cross-sectional study. A multistage cluster random sampling method was used to select the participants in Tehran in 2011. All the participants were interviewed by trained personnel using a standard questionnaire on diabetes as well as a socio-demographic checklist. Logistic regression and chi-square were used to investigate the association between diabetes and the demographic characteristics.

RESULTS

A total of 15069 older adults were included in this analysis. The mean age of the participants was 68.93±7.27years (SE: 0.059) and the mean of BMI was 26.21±4.40kg/m² (SE: 0.036). Prevalence of DT2 was 14.4% among Iranian older adults. Factors such as age, being female, high BMI, and education were significantly associated with DT2.

CONCLUSION

Given the high prevalence of diabetes among older people, more population based research is needed to quantify the ramifications of diabetes, and to monitor the effects of prevention and health system strengthening strategies on the prevalence, treatment, and control of DT2.

Prevalence of diabetes mellitus and its relation with obesity in Turaif (Saudi Arabia) in 2017

BACKGROUND

The significant increase in the prevalence of obesity over past decades caused the concomitant rise in the incidence of glucose intolerance and diabetes.

OBJECTIVE

To determine the prevalence of diabetes among Saudi nationals in Turaif, Kingdom of Saudi Arabia and to examine the association between diabetes and obesity in the studied population.

METHODS

This study was conducted during the period from May 01 to May 31, 2017. Data was collected from 402 individuals aged between 6-63 years via a predesigned questionnaire covering medical history of diabetes, age and sex. Body weight and height was measured to calculate BMI. Data were analyzed by SPSS version 15, using descriptive statistics and Chi-Square test.

RESULTS

Mean age (± SD) was 23.27 (±13.509) years, male to female ratio was 38.1% to 61.9%. The total prevalence of DM among the studied population was 4.5%, pre-diabetic cases were 7.5%. There is significant effect of age, sex and BMI on the occurrence of diabetes among the studied population (p<0.05).

CONCLUSIONS

Awareness campaigns and prevention programs about diabetes should be instituted and control strategies should be implemented. There is a need for a diabetes screening and management programs, focusing on access to health care in the city.

Sex and Race/Ethnicity Differences in Following Dietary and Exercise Recommendations for U.S. Representative Sample of Adults With Type 2 Diabetes

This study examined sex by race/ethnicity differences in medical advice received for diet and exercise with corresponding health behaviors of a U.S. representative sample of adults with type 2 diabetes ( N = 1,269). Data from the National Health and Nutrition Examination Surveys for 2011-2014 for 185 Mexican Americans, 123 Other Hispanics, 392 non-Hispanic Blacks, 140 non-Hispanic Asians, and 429 non-Hispanic Whites were analyzed using logistic regression analyses. Reporting being given dietary and exercise advice was positively associated with reporting following the behavior. There were differences in sex and sex by race/ethnicity for reporting receiving medical advice and performing the advised health behavior. These results suggest the importance of physicians having patient-centered communication skills and cultural competency when discussing diabetes management.

Physiological and psychological challenges of increasing physical activity and exercise in patients at risk of diabetic foot ulcers: a critical review

Obesity and a sedentary lifestyle are common challenges among individuals at risk of diabetic foot ulcers. While substantial research exists on physical activity interventions in adults with diabetes, those at greatest risk for foot ulceration were often excluded or not well represented. Both at-risk patients and their clinicians may be hesitant to increase physical activity because of their perception of diabetic foot ulcer risks. Physical activity is not contraindicated for those at risk of diabetic foot ulcer, yet patients at risk present with unique barriers to initiating increases in physical activity. This review focuses upon the physiological and psychological challenges of increasing physical activity and exercise in patients at risk of diabetic foot ulcers. Offloading, diabetic peripheral neuropathy, depression, pain, self-efficacy and social support, diabetic foot ulcer risk-specific beliefs and emotions, and research to date on exercise interventions in this population are all discussed. Additionally, recommendations for implementing and researching physical activity interventions for individuals at risk for diabetic foot ulcer are provided. Copyright © 2016 John Wiley & Sons, Ltd.

Type 2 Diabetes in the Elderly: Challenges in a Unique Patient Population

In the older patient population, rates of Type 2 Diabetes (T2D) and obesity are reaching epidemic proportions. In fact, older patients will soon constitute the majority of patients with T2D in most developed countries. The higher prevalence of T2D in older individuals is seen in both men and women and across racial and ethnic groups. However, certain ethnic groups are disproportionately affected and successful strategies must account for these fundamental differences. T2D in old age is associated with traditional diabetes-associated complications including micro- and macro vascular disease, but is also closely related to numerous other comorbidities including cognitive impairment, urinary incontinence, sarcopenia, and increased fall risk. An overall state of chronic inflammation and dysregulated immune system may underlie these increased risks; yet our understanding of immunometabolism during the aging process remains incomplete. In addition, optimal recognition and treatment of diabetes in the elderly is hampered by a lack of relevant, high-quality studies, as the majority of clinical trial data establishing risk profiles, glycemic targets, and therapeutic interventions for T2D are not applicable for large segments of the older patient population. Simply acknowledging this gap is inadequate. We need strong evidence-based data upon which to successfully identify diabetic patients and then intervene in ways that are targeted to specific individuals within a heterogeneous group of elderly patients with T2D.

Serum uric acid and low-density lipoprotein cholesterol levels are independent predictors of coronary artery disease in Asian Indian patients with type 2 diabetes mellitus

Aim:

We aimed to identify the predictors of coronary artery disease (CAD) in patients with type 2 diabetes mellitus (type 2 DM).

Methods:

About fifty Asian Indian patients with type 2 DM patients aged >40 years and fifty sex- and age-matched nondiabetic controls were enrolled for this study. Following complete medical history and baseline clinical data, laboratory investigations were performed to assess fasting and postprandial plasma glucose levels, lipid profile, blood urea, serum creatinine, and serum uric acid levels.

Results:

Body mass index (BMI), waist-to-hip ratio, serum uric acid, serum total cholesterol, low-density lipoprotein (LDL) cholesterol, triglycerides, very LDL cholesterol were significantly higher among diabetic patients compared to controls. On univariate analysis, serum LDL cholesterol (odds ratio [OR]: 29.67, P < 0.001), serum uric acid (OR: 25.65, P < 0.001), low high-density lipoprotein (HDL) cholesterol (OR: 21.12, P < 0.001), hypertension (OR: 17.06, P < 0.001), family history of cardiovascular disease (CVD) (OR: 9.43, P = 0.002), and duration of diabetes (OR: 4.65, P = 0.03) were identified as predictors of CVD among diabetic patients. On multivariate regression, only LDL cholesterol (OR: 1.51, P = 0.002) and serum uric acid (OR: 1.21, P = 0.01) were the independent predictors of CAD among diabetic patients. Significant positive correlation of serum uric acid with duration of diabetes (r = 0.38, P = 0.006), BMI (r = 0.35, P = 0.01), triglycerides (r = 0.356, P = 0.01), LDL cholesterol (r = 0.38, P = 0.007), HDL cholesterol (r = −0.514, P < 0.001), and hypertension (r = 0.524, P < 0.001) was observed.

Conclusion:

Serum LDL cholesterol and hyperuricemia may serve as independent predictors of CAD among Asian Indian subjects with type 2 DM.
