[Baseline risk of Diabetes Mellitus in Primary Health Care Services by FINDRISC test, associated factors and clinical outcome after 18 months of follow-up]. / Riesgo basal de Diabetes Mellitus en Atención Primaria según cuestionario FINDRISC, factores asociados y evolución clínica tras 18 meses de seguimiento.

OBJECTIVE: To estimate the risk of Diabetes Mellitus in Primary Health Care Services and diabetes incidence after 18 months of follow-up. MATERIAL AND METHODS: A multicenter study, with a first cross-sectional phase, to estimate the risk of Diabetes using the FINRISC test in 261 patients without Diabetes Mellitus treated in Primary Health Care Services. A second phase was carried out to assess Diabetes incidence after 18 months of follow-up. RESULTS: 19.5% had an elevated risk of Diabetes Mellitus (FINDRISC score ≥15). The independent variables after adjusting for gender, which are not included in the FINDRISC test and were associated with increased risk of Diabetes, were low educational level and chronic ischemia of lower limbs. After 18 months of follow-up, 7.8% of patients with FINDRISC score ≥15 developed Diabetes versus 1.9% of patients with FINDRISC score <15. CONCLUSIONS: One out of five patients without Diabetes who are treated in Primary Care Health Services have a FINDRISC score ≥15, this being associated with low educational level and peripheral vascular disease, regardless of gender. The FINDRISC score ≥15 has a short-term association with a high risk of developing Diabetes Mellitus.

SPROUTY-2 represses the epithelial phenotype of colon carcinoma cells via upregulation of ZEB1 mediated by ETS1 and miR-200/miR-150.

SPROUTY-2 (SPRY2) is a modulator of tyrosine kinase receptor signaling with receptor- and cell type-dependent inhibitory or enhancing effects. Studies on the action of SPRY2 in major cancers are conflicting and its role remains unclear. Here we have dissected SPRY2 action in human colon cancer. Global transcriptomic analyses show that SPRY2 downregulates genes encoding tight junction proteins such as claudin-7 and occludin and other cell-to-cell and cell-to-matrix adhesion molecules in human SW480-ADH colon carcinoma cells. Moreover, SPRY2 represses LLGL2/HUGL2, PATJ1/INADL and ST14, main regulators of the polarized epithelial phenotype, and ESRP1, an epithelial-to-mesenchymal transition (EMT) inhibitor. A key action of SPRY2 is the upregulation of the major EMT inducer ZEB1, as these effects are reversed by ZEB1 knock-down by means of RNA interference. Consistently, we found an inverse correlation between the expression level of claudin-7 and those of SPRY2 and ZEB1 in human colon tumors. Mechanistically, ZEB1 upregulation by SPRY2 results from the combined induction of ETS1 transcription factor and the repression of microRNAs (miR-200 family, miR-150) that target ZEB1 RNA. Moreover, SPRY2 increased AKT activation by epidermal growth factor, whereas AKT and also Src inhibition reduced the induction of ZEB1. Altogether, these data suggest that AKT and Src are implicated in SPRY2 action. Collectively, these results show a tumorigenic role of SPRY2 in colon cancer that is based on the dysregulation of tight junction and epithelial polarity master genes via upregulation of ZEB1. The dissection of the mechanism of action of SPRY2 in colon cancer cells is important to understand the upregulation of this gene in a subset of patients with this neoplasia that have poor prognosis.

[Effectiveness of PRECEDE model for health education in metabolic control and reduction of cardiovascular risk factors in patients with diabetes type 2]. / Eficacia del modelo PRECEDE, de educación para la salud, en el control metabólico y de los factores de riesgo cardiovascular en pacientes con diabetes mellitus tipo 2.

OBJECTIVE: To evaluate the effectiveness of PRECEDE model for health education, in the metabolic control and the reduction of cardiovascular risk factors, in type 2 diabetic patients followed for over two years in primary health care services. MATERIALS AND METHODS: PRECEDE model for health education was used in 318 patients with type 2 diabetes, from five primary health care centres. The study was conducted during two years of monitoring. RESULTS: After two years of follow-up was observed decrease in diastolic and systolic pressures (p < 0.05), as well as in levels of total cholesterol and LDL-cholesterol (p < 0.05). Patients with good metabolic control (glycated hemoglobin A1c < 7% and LDL cholesterol < 100 mg/dl), increased from 9.9% to 16.8% (p < 0,05). On the other hand, 27% of patients improved their level of therapeutic adherence, and there was a decreased in the number of patients with microalbuminuria from 8.4% to 6.3% (p = 0.05). Finally, we found no differences in levels of glycated hemoglobin A1c, BMI and cardiovascular risk. Mortality after two years was 0.7%. DISCUSSION: PRECEDE model for health education is a useful method in the management of type 2 diabetes, that reduce the levels of blood pressure both systolic and diastolic, decrease the lipid levels, and improve the level of therapeutic adherence in type 2 diabetic patients, followed for two years.

[Factors associated to influenza vaccination in people over 60 years seen in primary care]. / Factores asociados a la vacunación de la gripe en individuos mayores de 60 años atendidos en Atención Primaria.

INTRODUCTION: The improvement in the vaccination levels against influenza depend on the knowledge had on why the target population rejects vaccination. MATERIALS AND METHODS: A descriptive and cross-sectional study on influenza vaccination prevalence in people over 59 years, in the assigned quota of a Primary Health Center during the year 2005 campaign. RESULTS: A total of 557 individuals were analyzed of these, 57.8% (n = 322) had received the influenza vaccine, while 42.2% (n = 235) were not vaccinated during the study period. The main reasons for rejection of vaccination were no colds and fear a worsening of baseline conditions. DISCUSSION: Rejection of the influenza vaccination is not due to scientific reasons, and therefore vaccination levels can improve through better information.
