RESUMO
Introduction: Clinical practice guidelines are helpful for clinicians, and their proper implementation could improve the quality of care and management of participants with diabetes. This study aimed to evaluate the degree of adherence to the Clinical Practice Guidelines (CPG) recommendations among obese, frail, or recently diagnosed type 2 diabetes mellitus (T2DM) participants in primary care centers in Spain. Methods: We perform a cross-sectional study on a national level in two phases. In the first phase, study participants were recruited, and their clinical data were collected. In the second phase, data related to the participating physicians were collected. Results: In total, 882 participants from 240 physicians were analyzed. According to the study questionnaire, most participants from all three clinical groups had adequate adherence to the CPG. This percentage was highest among the recently diagnosed T2DM (91.6%) and lowest percent of frail T2DM persons (74.7%). The inadequate adherence to the guidelines was observed mainly among the obese and frail participants with T2DM from medical doctors with low CPG knowledge (3.4% and 3.5%, respectively). Regarding the patient's characteristics and degree of adherence to the guidelines, the participants with inadequate adherence were generally older, with higher BMI, poorer HbA1c control, and fewer visits with primary care physicians. Most (57%) primary care physicians had moderate CPG knowledge. In our multivariable logistic model, we did not observe statistically significant odds ratios for different characteristics related to the physicians/consultation and low CPG knowledge. Discussion: The results of our cross-sectional study observe adequate adherence to the clinical guidelines by the primary care physicians for the majority of the participants with obesity, frailty, or newly diagnosed with T2DM.
RESUMO
Background: Tuberculosis is the leading cause of mortality from lung infectious disease worldwide in recent years, and its incidence has re-emerged in large cities in low-incidence countries due to migration and socioeconomic deprivation causes. Diabetes mellitus and tuberculosis are syndemic diseases, with diabetes being considered a risk factor for developing tuberculosis. Objective: To investigate whether diabetic patients were at increased risk of tuberculosis living in an inner-district of a large city of northeastern Spain. Methods: Observational matched retrospective cohort study based on clinical records from the population of the lowest socioeconomic status in Barcelona (Ciutat Vella district). A cohort including patients with type 1 and type 2 diabetes mellitus in 2007 and new cases until 2016 (8004 subjects), matched 1:1 by sex and age with a non-diabetic cohort. Follow-up period was until December 31st 2018. We evaluated the risk of developing tuberculosis in diabetic patients compared to non-diabetic patients during the follow up period. We used time-to-event analysis to estimate the incidence of tuberculosis, and competing risks regression by clusters and conditional Cox regression models to calculate the hazard ratio (HR) and its 95% confidence intervals (CI). Results: Among the 16,008 included subjects, the median follow-up was 8.7 years. The mean age was 57.7 years; 61.2% men and 38.8% women in both groups. The incidence of tuberculosis was 69.9 per 100,000 person-years in diabetic patients, and 40.9 per 100,000 person-years in non-diabetic patients (HR = 1.90; CI: 1.18-3.07). After adjustment for the country of origin, chronic kidney disease, number of medical appointments, BMI, alcoholism and smoking, the risk remained higher in diabetic patients (1.66: CI 0.99-2.77). Additionally, subjects from Hindustan or with a history of alcohol abuse also showed a higher risk of developing tuberculosis (HR = 3.51; CI:1.87-6.57, and HR = 2.73; CI:1.22-6.12 respectively). Conclusion: People with diabetes mellitus were at higher risk of developing tuberculosis in a large cohort recruited in an inner-city district with a high incidence for this outcome, and low socioeconomic conditions and high proportion of migrants. This risk was higher among Hindustan born and alcohol abusers.

The purpose of this study was to assess the risk of occurrence of Parkinson's disease (PD) among subjects with type 2 diabetes and diabetic retinopathy (DR) in our large primary health care database from Catalonia (Spain). A retrospective cohort study with pseudo-anonymized routinely collected health data from SIDIAP was conducted from 2008 to 2016. We calculated the number of events, time to event, cumulative incidence, and incidence rates of PD for subjects with and without DR and for different stages of DR. The proportional hazards regression analysis was done to assess the probability of occurrence between DR and PD. In total, 26,453 type 2 diabetic subjects with DR were identified in the database, and 216,250 subjects without DR at inclusion. During the follow-up period, 1,748 PD events occurred. PD incidence rate and cumulative incidence were higher among subjects with DR (16.95 per 10,000 person-years and 0.83%, respectively). In the unadjusted analysis, subjects with DR were at 1.25 times higher risk (hazard ratio: 1.22, 95% confidence interval: 1.06; 1.41) of developing PD during the study period. However, we did not find any statistically significant HR for DR in any models after adjusting for different risk factors (age, sex, duration of diabetes, smoking, body mass index, glycosylated hemoglobin, comorbidities). In conclusion, in our primary health care population database, DR was not associated with an increased risk of PD after adjusting for different risk factors. In our retrospective cohort study, age, male sex, and diabetes duration were independent risk factors for developing PD.
RESUMO
PURPOSE: To describe the distribution of Type 2 DM retinal lesions and determine whether it is symmetrical between the two eyes, is random or follows a certain pattern. METHODS: Cross-sectional study of Type 2 DM patients who had been referred for an outpatients' ophthalmology visit for diabetic retinopathy screening in primary health care. Retinal photographic images were taken using central projection non-mydriatic retinography. The lesions under study were microaneurysms/haemorrhages, and hard and soft exudates. The lesions were placed numerically along the x- and y-axes obtained, with the fovea as the origin. RESULTS: From among the 94 patients included in the study, 4770 lesions were identified. The retinal lesions were not distributed randomly, but rather followed a determined pattern. The left eye exhibited more microaneurysms/haemorrhages and hard exudates of a greater density in the central retina than was found in the right eye. Furthermore, more cells containing lesions were found in the upper temporal quadrants, (especially in the left eye), and tended to be more central in the left eye than in the right, while the hard exudates were more central than the microaneurysms/haemorrhages. CONCLUSION: The distribution of DR lesions is neither homogeneous nor random but rather follows a determined pattern for both microaneurysms/haemorrhages and hard exudates. This distribution means that the areas of the retina most vulnerable to metabolic alteration can be identified. The results may be useful for automated DR detection algorithms and for determining the underlying vascular and non-vascular physiopathological mechanisms that can explain these differences.

Treatment of diabetes mellitus type2 (DM2) includes healthy eating and exercise (150minutes/week) as basic pillars. For pharmacological treatment, metformin is the initial drug except contraindication or intolerance; in case of poor control, 8 therapeutic families are available (6 oral and 2 injectable) as possible combinations. An algorithm and some recommendations for the treatment of DM2 are presented. In secondary cardiovascular prevention, it is recommended to associate an inhibitor of the sodium-glucose cotransporter type 2 (iSGLT2) or a glucagon-like peptide-1 receptor agonist (arGLP1) in patients with obesity. In primary prevention if the patient is obese or overweight metformin should be combined with iSGLT2, arGLP1, or inhibitors of type4 dipeptidylpeptidase (iDPP4). If the patient does not present obesity, iDPP4, iSGLT2 or gliclazide, sulfonylurea, recommended due to its lower tendency to hypoglycaemia, may be used.

BACKGROUND: Our objective of this study was to determine if rate of estimated glomerular filtration rate (eGFR) decline and its intensity was associated with cardiovascular risk and death in patients with hypertension whose baseline eGFR was higher than 60 ml/minute/1.73 m2. METHODS: This study comprised 2,516 patients with hypertension who had had at least 2 serum creatinine measurements over a 4-year period. An eGFR reduction of ≥10% per year has been deemed as high eGFR and a reduction in eGFR of less than 10% per year as a low decline. The end points were coronary artery disease, stroke, transitory ischemic accident, peripheral arterial disease, heart failure, atrial fibrillation, and death from any cause. Cox regression analyses adjusted for potentially confounding factors were conducted. RESULTS: A total of 2,354 patients with low rate of eGFR decline and 149 with high rate of eGFR decline were analyzed. The adjusted model shows that a -10% rate of eGFR decline per year is associated with a higher risk of the primary end point (HR 1.9; 95% CI 1.1-3.5; P = 0.02) and arteriosclerotic vascular disease (HR 2.2; 95% CI 1.2-4.2; P < 0.001) in all hypertensive groups. The variables associated to high/low rate of eGFR decline in the logistic regression model were serum creatinine (OR 3.35; P < 0.001), gender, women (OR 15.3; P < 0.001), tobacco user (OR 1.9; P < 0.002), and pulse pressure (OR 0.99; P < 0.05). CONCLUSIONS: A rate of eGFR decline equal to or higher than -10% per year is a marker of cardiovascular risk for patients with arterial hypertension without chronic kidney disease at baseline. It may be useful to consider intensifying the global risk approach for these patients.

AIMS: To determine the relationship between diabetic nephropathy and diabetic retinopathy on a population of type 2 diabetes mellitus patients. METHODS: A prospective ten-year follow-up population-based study. We determined differences between estimated glomerular filtration rate (eGFR) using the chronic kidney disease epidemiology collaboration equation and urine albumin to creatinine ratio. RESULTS: Annual incidence of any-DR was 8.21 ± 0.60% (7.06%-8.92%), sight-threatening diabetic retinopathy (STDR) was 2.65 ± 0.14% (2.48%-2.88%), and diabetic macular edema (DME) was 2.21 ± 0.18% (2%-2.49%). Renal study results were as follows: UACR > 30 mg/g had an annual incidence of 7.02 ± 0.05% (6.97%-7.09%), eGFR < 60 ml/min/1.73 m2 incidence was 5.89 ± 0.12% (5.70%-6.13%). Cox's proportional regression analysis of DR incidence shows that renal function studied by eGFR < 60 ml/min/1.73 m2 was less significant (p = 0.04, HR 1.223, 1.098-1.201) than UACR ≥ 300 mg/g (p < 0.001, HR 1.485, 1.103-1.548). The study of STDR shows that eGFR < 60 ml/min/1.73 m2 was significant (p = 0.02, HR 1.890, 1.267-2.820), UACR ≥ 300 mg/g (p < 0.001, HR 2.448, 1.595-3.757), and DME shows that eGFR < 60 ml/min/1.73 m2 was significant (p = 0.02, HR 1.920, 1.287-2.864) and UACR ≥ 300 mg/g (p < 0.001, HR 2.432, 1.584-3.732). CONCLUSIONS: The UACR has a better association with diabetic retinopathy than the eGFR, although both are important risk factors for diabetic retinopathy.

BACKGROUND AND AIMS: The possible contribution of iron to cardiovascular complications of type 2 diabetes (T2D) has been scarcely investigated. We aimed to study whether serum ferritin is linked to prevalent/incident cardiovascular disease (CVD) in T2D. METHODS: The prevalence of coronary heart disease (CHD), cerebrovascular disease (CEVD) and CVD was evaluated in the SIDIAP study (nâ¯=â¯38,617) and prevalence and 7-year incidence were analysed in the Edinburgh Type 2 Diabetes Study (ET2DS) (nâ¯=â¯821). Logistic and Cox regressions were used to describe associations between serum ferritin and CVD adjusting for confounding variables. RESULTS: Increase of 1 SD unit in log-ferritin was associated with lower CVD prevalence in fully-adjusted models (ET2DS odds ratio (OR) 95% confidence interval (CI): 0.81 (0.68-0.96), pâ¯=â¯0.018; SIDIAP study: 0.91 (0.88-0.94), pâ¯<â¯0.001). In ET2DS, ferritin in the highest (vs. the lowest) quintile was associated with lower incidence of CVD (fully adjusted HR 95% CI: 0.46 (0.26-0.83), pâ¯=â¯0.010). This association persisted after removing subjects with CVD at baseline (nâ¯=â¯536) (HR 95% CI: 0.34 (0.14-0.81), pâ¯=â¯0.016). CONCLUSIONS: Low iron status was associated with CVD risk in T2D. This pattern was consistent in populations at different cardiovascular risk. Low iron status seems to be harmful for cardiovascular health in T2D and it may be a target for intervention.

AIM: The aim of this study was to assess glycaemic control and prescribing practices of antihyperglycaemic treatment in patients with diabetes mellitus type 2 aged 75 years or older. METHODS: We analysed data from health electronic records from 4,581 persons attended at primary healthcare centres of the Institut Català de la Salut (ICS), in the Girona Sud area of Catalonia, Spain, during 2013 and 2016. Variables such as age, gender, body mass index (BMI), diabetes duration, age at diabetes diagnosis, glycated haemoglobin (HbA1c), creatinine, glomerular filtrate rate and the albumin/creatinine ratio in urine were collected. A descriptive analysis of the study variables was done to determinate the percentage of persons on antidiabetic treatment. RESULTS: We identified 4,421 persons aged 75 years or older who provided data on HbA1c and antidiabetic treatment. Mean age was 82.3 (5.1) years. In 58.1% of patients, the level of HbA1c was below 7.0%, while in 36.8% it was below 6.5%. Between patients with HbA1c below 7.0%, antidiabetic drugs were taken by 70.2%, where 15.2% were either on insulin, sulphonylureas or repaglinide therapy. CONCLUSION: Intensive treatment among older adults with diabetes mellitus type 2 is common in primary care clinical practice in our area. Intensive glycaemic control confers an increased risk of hypoglycaemia and little benefit among older individuals with diabetes. Physicians should take care more not to harm those populations and treatment should be de-intensified to reduce the risk of hypoglycaemia.

PURPOSE: To explore the relationship between chronic kidney disease (CKD) and diabetic retinopathy (DR) in a representative population of type 2 diabetes mellitus (DM2) patients in Catalonia (Spain). METHODS: This was a population-based, cross-sectional study. A total of 28,344 patients diagnosed with DM2 who had recorded ophthalmologic and renal functional examinations were evaluated. Data were obtained from a primary healthcare electronic database of medical records. CKD was defined as an estimated glomerular filtration ratio (eGFR) of <60 ml/min/1.73 m2 and/or urine albumin to creatinine ratio (UACR) ≥30 mg/g. DR was categorized as non-vision threatening diabetic retinopathy and vision threatening diabetic retinopathy. RESULTS: CKD was associated with a higher rate of DR [OR], 95% confidence interval [CI], 1.5 (1.4-1.7). When we analyzed the association between different levels of UACR and DR prevalence observed that DR prevalence rose with the increase of UACR levels, and this association was significant from UACR values ≥10 mg/g, and increased considerably with UACR values ≥300 mg/g (Odds ratio [OR], 95% confidence interval [CI], 2.0 (1.6-2.5). This association was lower in patients with eGFR levels 44 to 30 mL/min/1.73 m2 [OR], 95% confidence interval [CI], 1.3 (1.1-1.6). CONCLUSIONS: These results show that CKD, high UACR and/or low eGFR, appear to be associated with DR in this DM2 population.

BACKGROUND: Some authors consider that secondary prevention should be conducted for all DM2 patients, while others suggest that the drug preventive treatment should start or be increased depending on each patient's individual CVR, estimated using cardiovascular or coronary risk functions to identify the patients with a higher CVR. The principal objective of this study was to assess three different cardiovascular risk prediction models in type 2 diabetes patients. METHODS: Multicentre, cross-sectional descriptive study of 3,041 patients with type 2 diabetes and no history of cardiovascular disease. The demographic, clinical, analytical, and cardiovascular risk factor variables associated with type 2 diabetes were analysed. The risk function and probability that a cardiovascular disease could occur were estimated using three risk engines: REGICOR, UKPDS and ADVANCE. A patient was considered to have a high cardiovascular risk when REGICOR ≥ 10 % or UKPDS ≥ 15 % in 10 years or when ADVANCE ≥ 8 % in 4 years. RESULTS: The ADVANCE and UKPDS risk engines identified a higher number of diabetic patients with a high cardiovascular risk (24.2 % and 22.7 %, respectively) compared to the REGICOR risk engine (10.2 %). The correlation using the REGICOR risk engine was low compared to UKPDS and ADVANCE (r = 0.288 and r = 0.153, respectively; p < 0.0001). The agreement values in the allocation of a particular patient to the high risk group was low between the REGICOR engine and the UKPDS and ADVANCE engines (k = 0.205 and k = 0.123, respectively; p < 0.0001) and acceptable between the ADVANCE and UKPDS risk engines (k = 0.608). CONCLUSIONS: There are discrepancies between the general population and the type 2 diabetic patient-specific risk engines. The results of this study indicate the need for a prospective study which validates specific equations for diabetic patients in the Spanish population, as well as research on new models for cardiovascular risk prediction in these patients.

BACKGROUND/AIMS: Retinal photography with a non-mydriatic camera is the method currently employed for diabetic retinography (DR) screening. We designed this study in order to evaluate the prevalence and severity of DR, and associated risk factors, in patients with type 2 diabetes (T2DM) screened in Catalan Primary Health Care. METHODS: Retrospective, cross-sectional, population based study performed in Catalonia (Spain) with patients with T2DM, aged between 30 years and 90â years (on 31 December 2012) screened with retinal photography and whose DR category was recorded in their medical records. DR was classified as: no apparent retinopathy (no DR), mild non-proliferative DR (mild NPDR), moderate NPDR, severe NPDR, proliferative DR (PDR) and diabetic macular oedema (DMO). Non-vision threatening DR (non-VTDR) included mild and moderate NPDR; VTDR included severe NPDR, PDR and DMO. Clinical data were obtained retrospectively from the SIDIAP database (System for Research and Development in Primary Care). RESULTS: 108â 723 patients with T2DM had been screened with retinal photography. The prevalence of any kind of DR was 12.3% (95% CI 12.1% to 12.5%). Non-VTDR and VTDR were present in 10.8% (mild 7.5% and moderate NPDR 3.3%) and 1.4% (severe NPDR 0.86%, PDR 0.36% and DMO 0.18%) of the study patients, respectively. CONCLUSIONS: The prevalence of any type of DR in patients with T2DM screened with retinal photography was lower when compared with earlier studies.

BACKGROUND: The presence of chronic kidney disease (CKD) in type 2 diabetes mellitus (T2DM) increases the risk of cardiovascular disease (CVD) regardless of the presence of traditional cardiovascular risk factors. There is controversy about the impact of each of the manifestations of CKD on the prevalence of CVD, whether it is greater with decreased estimated glomerular filtration rate (eGFR) or increased urine albumin creatinine ratio (UACR). METHODS: This study is a national cross-sectional study performed in primary care consults. We selected participants of both sexes who were aged 40 years or older, had been diagnosed with T2DM and had complete information on the study variables recorded in their medical records. The participants were classified according to eGFR : ≥ 60; 45-59; 30-44; <30 mL/min/1.73 m(2) and UACR : < 30; 30-299; ≥ 300 mg/gr. The results were adjusted to compare the prevalence of CVD across all categories. RESULTS: A total of 1141 participants were included. Compared to participants with eGFR > 60 mL/min/1.73 m(2) those with eGFR between 30-44 mL/min/m(2), (OR = 2.3; 95% CI, 1.4-3.9); and eGFR < 30 mL/min/1.73 m(2) (OR = 4.1 95% CI 1.6-10.2) showed increased likelihood of having CVD. Participants with UACR ≥ 30 mg/g compared to participants with UACR < 30 mg/g increased significantly the likelihood of having CVD, especially with UACR above 300 mg/g, (OR = 1.6; 95% CI 1.1-2.4 for UACR = 30-299 mg/g; OR = 3.9; CI 1.6-9.5 for UACR ≥ 300 mg/g). CONCLUSION: The decrease in eGFR and increase in UACR are independent risk factors that increase the prevalence of CVD in participants with T2DM and these factors are independent of each other and of other known cardiovascular risk factors. In our study the impact of mild decreased eGFR in T2DM on CVD was lower than the impact of increased UACR. It is necessary to determine not only UACR but also eGFR for all patients with T2DM, both at the time of diagnosis and during follow-up, to identify those patients at high risk of cardiovascular complications.

There is no agreement on the systematic exploration of the fundus oculi (FO) in hypertensive patients, and it is unknown whether the evolution of retinal microcirculatory alterations has prognostic value or not. The aim of this study was to investigate whether the evolution of the arteriole-to-venule ratio (AVR) in newly-diagnosed hypertensive patients is associated with better or worse evolution of target organ damage (TOD) during 1 year. A cohort of 133 patients with newly-diagnosed untreated hypertension was followed for 1 year. At baseline and follow-up, all patients underwent a physical examination, self-blood pressure measurement, ambulatory blood pressure monitoring, blood and urine analysis, electrocardiogram, and retinography. The endpoint was the favourable evolution of TOD and the total amount of TOD, according to the baseline AVR and the baseline and final difference of the AVR. A total of 133 patients were analyzed (mean age, 57 ± 10.7 years; 59% men). No differences were found in the decrease in blood pressure or antihypertensive treatment between quartiles of baseline AVR or baseline-final AVR difference. Patients with a difference between baseline and final AVR in the highest quartile (>0.0817) had a favorable evolution of left ventricular hypertrophy (odds ratio, 14.9; 95% confidence interval, 1.08-206.8) and the amount of TOD (odds ratio, 2.22; 95% confidence interval, 1.03-6.05). No favorable evolution was found of glomerular filtration rate. There is an association between the evolution of the AVR and the favorable evolution of TOD. Patients with greater increase of AVR have significantly better evolution of left ventricular hypertrophy and amount of TOD.

BACKGROUND: The objective of this study was to determinate the prevalence of chronic kidney disease (CKD) and the different stages of CKD in patients with type 2 diabetes mellitus (DM2) treated in primary care consults in Spain. METHODS: A national cross-sectional study was performed in primary care consults. The following data were collected: demographic and anthropometric information; list of present cardiovascular risk factors (CVRF); previous macrovascular and microvascular disease history; physical examination and analytical data from the previous 12 months, including the urine albumin-creatinine ratio (UACR) and estimated glomerular filtration rate (eGFR) to evaluate renal function. RESULTS: With regard to the patients, 27.9% presented some degree of CKD as follows: 3.5% with stage 1; 6.4% with stage 2; 16.8% with stage 3 (11.6% with stage 3A and 5.2% with stage 3B); and 1.2% with stages 4 and 5. The prevalence of patients with UACR ≥ 30 mg/g was 15.4% (13% microalbuminuria and 2.4% macroalbuminuria). Renal impairment (RI) was found in 206 patients (18%) of whom 133 patients (64.6%) was stage 3A, 60 patients (29.1%) was stage 3B and 13 patients (6.3%) stages 4 and 5. Among patients with RI, 143 patients (69.4%) had normoalbuminuria. The following variables were significantly associated with CKD: age; sex (women); systolic arterial blood pressure (SABP) ≥ 150 mmHg; and a previous history of cardiovascular disease. CONCLUSIONS: The results showed that the prevalence for any type of CKD was 27.9%. A systematic determination of UACR and eGFR may contribute to an early diagnosis, thus allowing intervention during the initial stages of the disease when treatment is more efficient.
