Treatment Adherence and Its Associated Factors in Patients with Type 2 Diabetes: Results from the Rio de Janeiro Type 2 Diabetes Cohort Study.

OBJECTIVES: To investigate treatment adherence in patients with type 2 diabetes and to evaluate its associated factors. METHODS: The Summary of Diabetes Self-Care Activities (SDSCA) questionnaire was used to assess treatment adherence. Good adherence was defined as ≥5 days a week in each SDSCA item. Pain, emotional, and physical domains of the SF-36 quality of life questionnaire and the Canadian Occupational Performance Measure (COPM) were also evaluated. Multivariable logistic regressions explored the independent correlates of good general adherence and of specific items of the SDSCA (diet, exercise, and medications). RESULTS: Good adherence was 93.5% for medication use, 59.3% for foot care, 56.1% for blood glucose monitoring, 29.2% for diet, and 22.5% for exercise. Patients with general good adherence had lower BMI, better serum lipid profile, higher values of functional capacity, emotional and pain domains of SF-36, better occupational performance, and lower prevalence of pain or limitation in the upper and lower limbs than patients with worse adherence. The variables associated with good adherence were younger age, lower BMI, presence of macrovascular complications, better occupational performance and emotional domain of SF-36, and higher HDL cholesterol levels. The presence of pain/limitation in the upper limbs was associated with worse adherence. Good medication adherence was associated with longer diabetes duration, lower BMI, and lower HbA1c levels. Higher values of pain and emotional domains of the SF-36 and lower BMI were related to better exercise and diet adherence, while the presence of peripheral neuropathy and joint pain/limitation were associated with worse exercise adherence. CONCLUSIONS: Emotional and physical performances are important determinants of good diabetic treatment adherence. Good adherence has beneficial impact on BMI, lipid, and glycemic control.

Mini-trampoline enhances cardiovascular responses during a stationary running exergame in adults.

A new class of video game called exergame (EXG) has been used to promote physical activity and cardiovascular fitness, but EXGs are not as efficient as traditional aerobic exercises. However, auxiliary tools, such as the mini trampoline (MT), may enhance the physiological responses obtained by the EXG. The aim of this study was to compare the metabolic and cardiovascular responses of a stationary running EXG with and without an MT. Nineteen healthy males performed a treadmill test for the determination of VO2max and HRmax. In sequence, the VO2, HR, and METs were measured during the Free Run, a Nintendo Wii's stationary running EXG, according to two distinct protocols. One protocol used the traditional EXG (EXG-PT), and the other protocol used an MT during the EXG (MT-PT). The normalized data were analyzed by statistical software SPSS 20.0 using a t-test and ANOVA for repeated measures (p < 0.05). The results supported that stationary running EXG performed on an MT showed an increased intensity, in all variables analyzed, when compared with the traditional EXG. Furthermore, the MT-PT was classified as a vigorous-intensity exercise and EXG-PT as a moderate to vigorous intensity exercise. In conclusion, these findings support that the MT is a feasible auxiliary tool to enhance physiologic responses during a stationary running EXG.

EEF1D modulates proliferation and epithelial-mesenchymal transition in oral squamous cell carcinoma.

EEF1D (eukaryotic translation elongation factor 1δ) is a subunit of the elongation factor 1 complex of proteins that mediates the elongation process during protein synthesis via enzymatic delivery of aminoacyl-tRNAs to the ribosome. Although the functions of EEF1D in the translation process are recognized, EEF1D expression was found to be unbalanced in tumours. In the present study, we demonstrate the overexpression of EEF1D in OSCC (oral squamous cell carcinoma), and revealed that EEF1D and protein interaction partners promote the activation of cyclin D1 and vimentin proteins. EEF1D knockdown in OSCC reduced cell proliferation and induced EMT (epithelial-mesenchymal transition) phenotypes, including cell invasion. Taken together, these results define EEF1D as a critical inducer of OSCC proliferation and EMT.

Profile of disabilities and their associated factors in patients with type 2 diabetes evaluated by the Canadian occupational performance measure: the Rio De Janeiro type 2 diabetes cohort study.

PURPOSE: To investigate the profile of disability in patients with type 2 diabetes and to evaluate its associated variables. METHOD: The Canadian Occupational Performance Measure (COPM) assessed disabilities in 475 type 2 diabetic individuals. The activities were categorised by the International Classification of Functioning, Disability and Health. The Medical Outcomes Study 36-item Short-Form Health Survey (SF-36) was used to evaluate pain, emotional and physical functioning domains of life-quality. Multivariable logistic regression assessed the independent correlates of better/worse performance. RESULTS: Median COPM score was 4.5 (interquartile range 3-6). Problems in mobility (53.6%), self-care (21.1%) and daily-life (13.0%) were most frequently self-reported. Presence of restriction/pain in the upper limbs (odds ratio [OR]: 1.66; 95% CI: 1.11-2.47; p=0.013) and of peripheral neuropathy (OR: 1.64; 95% CI: 1.06-2.53; p=0.026) were associated with greater chance of worse performance. Higher values of SF-36 in pain and emotional domains (each 10 point increase; OR: 0.92 95% CI: 0.85-0.98; p=0.011; OR: 0.96; 95% CI: 0.92-1.00; p=0.063, respectively) and physical activity (OR: 0.63; 95% CI: 0.41-0.98; p=0.042) were associated with better performance. CONCLUSIONS: Type 2 diabetic patients frequently reported disabilities in mobility, self-care and daily-life domains; and its associated factors were the presence of depression, upper limb pain and diabetic peripheral neuropathy. Implications for Rehabilitation The Canadian Occupational Performance Measure (COPM) instrument can be applied to patients with diabetes, as it identifies several disabilities, mostly in mobility, self-care and domestic life areas. Rehabilitation directed to upper limb pain/limitation and to lower limb peripheral neuropathy shall be implemented and may improve diabetic patients' performance and quality of life. A patient-centered rehabilitation strategy, guided by the COPM, may enable greater independence and autonomy, but this should be confirmed in future intervention studies.

Deficiência de ferro em lactentes brasileiros com doença falciforme / Iron deficiency in Brazilian infants with sickle cell disease

OBJETIVO: Avaliar a deficiência ou sobrecarga de ferro em lactentes com doença falciforme, a fim de embasar a decisão de recomendar (ou não) a suplementação profilática de ferro nessa população. MÉTODOS: Estudo retrospectivo transversal envolvendo 135 lactentes menores de 2 anos (66 meninos e 69 meninas), com genótipos SS e SC (77/58), nascidos entre 2005 e 2006 em Minas Gerais. Os indicadores de uma possível deficiência de ferro foram: volume corpuscular médio (VCM), hemoglobina corpuscular média (HCM), saturação da transferrina (ST) e ferritina. Dezessete lactentes [12,6 por cento, intervalo de confiança de 95 por cento (IC95 por cento) 7,0-18,2 por cento] haviam recebido hemotransfusão antes da coleta dos exames. RESULTADOS: ST e ferritina estavam significativamente mais baixas nos lactentes com hemoglobina SC (p < 0,001). Quando dois indicadores foram utilizados para definir a deficiência de ferro (VCM ou HCM baixos mais ST ou ferritina baixas), 17,8 por cento das crianças (IC95 por cento 11,3-24,3 por cento) tinham deficiência de ferro, predominando naquelas com perfil SC (p = 0,003). Análise das crianças que não haviam sido transfundidas (n = 118) mostrou prevalência de ferropenia em 19,5 por cento. Constatou-se aumento de ferritina em 15 lactentes (11,3 por cento; IC95 por cento 5,9-16,7 por cento); a maioria havia sido transfundida. CONCLUSÕES: A maior parte dos lactentes com doença falciforme não desenvolve deficiência de ferro, mas alguns têm déficit significativo. Este estudo indica que lactentes com doença falciforme, principalmente aqueles com hemoglobinopatia SC, talvez possam receber ferro profilático; no entanto, a suplementação deve ser suspensa após a primeira hemotransfusão.

OBJECTIVE: To assess iron deficiency or overload in infants with sickle cell disease in order to support the decision to recommend (or not) iron prophylactic supplementation in this population. METHODS: Cross-sectional and retrospective study with 135 infants below 2 years old (66 boys and 69 girls), 77 with SS and 58 with SC hemoglobin, born between 2005 and 2006 in Minas Gerais, Brazil. Indicators of possible iron deficiency were: mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), transferrin saturation (TS), and ferritin. Blood transfusions had been given to 17 infants (12.6 percent, 95 percent confidence interval [95 percentCI] 7.0-18.2 percent) before laboratory tests were done. RESULTS: Ferritin and TS were significantly lower in SC infants (p < 0.001). When two indices were considered for the definition of iron deficiency (low MCV or MCH plus low ferritin or TS), 17.8 percent of children (95 percentCI 11.3-24.3 percent) presented iron deficiency, mainly those with SC hemoglobin (p = 0.003). An analysis of infants who were not given transfusions (n = 118) showed that 19.5 percent presented iron deficiency. Fifteen infants (11.3 percent, 95 percentCI 5.9-16.7 percent) presented increased ferritin; the majority had been transfused. CONCLUSIONS: Most infants with sickle cell disease do not develop iron deficiency, though some have a significant deficit. This study indicates that infants with sickle cell disease, mainly those with SC hemoglobin, may receive prophylactic iron; however, supplementation should be withdrawn after the first blood transfusion.
