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.

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.

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%, 95% confidence interval [95%CI] 7.0-18.2%) 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% of children (95%CI 11.3-24.3%) 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% presented iron deficiency. Fifteen infants (11.3%, 95%CI 5.9-16.7%) 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.

ResumoObjetivo: 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. 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% das crianças (IC95% 11,3-24,3%) 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%. Constatou-se aumento de ferritina em 15 lactentes (11,3%; IC95% 5,9-16,7%); a maioria havia sido transfundida. Métodos 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.J Pediatr (Rio J). 2011;87(5):405-11: Doença falciforme, deficiên-cia de ferro, ferritina, transtornos de alimentação na infância, triagem neonatal.
