RESUMO

Metabolic biomarkers, particularly glycated hemoglobin and fasting plasma glucose, are pivotal in the diagnosis and control of diabetes mellitus. Despite their importance, they exhibit limitations in assessing short-term glucose variations. In this study, we propose labile hemoglobin as an additional biomarker, providing insightful perspectives into these fluctuations. By utilizing datasets from 40,652 retrospective general participants and conducting glucose tolerance tests on 60 prospective pediatric subjects, we explored the relationship between plasma glucose and labile hemoglobin. A mathematical model was developed to encapsulate short-term glucose kinetics in the pediatric group. Applying dimensionality reduction techniques, we successfully identified participant subclusters, facilitating the differentiation between diabetic and non-diabetic individuals. Intriguingly, by integrating labile hemoglobin measurements with plasma glucose values, we were able to predict the likelihood of diabetes in pediatric subjects, underscoring the potential of labile hemoglobin as a significant glycemic biomarker for diabetes research.

RESUMO

Aims:The aim of this study is to analyse the effect of pharmacological and non-pharmacological treatment on weight control in patients with diabetes and obesity. Design: Epidemiological, descriptive, cross-sectional study. Site: Primary care. In 11 health centres in Málaga and Cádiz during April and October 2022. Participants: 281 patients over 18 years old with type 2 diabetes and obesity are included. Main measurements: Socio-demographics, clinical, treatment and lifestyle habits variables were obtained from medical records and personal interview. Descriptive statistics were obtained for continuous variables. Statistical tests were performed based on the nature of the variables. Results: Variables like marital status, level of education and occupation, and smoking habit, shows differences regarding the sex (p<0.05). 82.3% of those who received education lost weight, compared to 67.5% of lost weight who received no health education (p=0.004). GLP1 and SGLT2 were more commonly prescribed for women (p=0.048), and SGLT2 more commonly prescribed for men (p=0.047). Patients taking GLP1, SGLT2 or both, regardless of sex, weight loss during the study period was −3.1kg (SE: 0.60), while the loss of those who took other medications was −1.33kg (SE: 0.62). The mean difference was 1.75kg (p=0.046). Conclusions: In terms of weight loss, obese diabetics who took GLP1, SGLT2 or both were 2.5 times more likely to lose weight than those who did not. Healthy lifestyle choices are key to weight loss in obese diabetic patients.(AU)


Objetivo: Analizar el efecto del tratamiento farmacológico y no farmacológico en el control del peso en pacientes diabéticos obesos. Diseño: Estudio epidemiológico, descriptivo y transversal. Emplazamiento: Atención primaria: 11 centros de salud en Málaga y Cádiz durante abril y octubre de 2022. Participantes: Fueron incluidos 281 pacientes mayores de 18 años con diabetes tipo 2 y obesidad. Mediciones principales: Se obtuvieron variables sociodemográficas, clínicas, de tratamiento y de hábitos de vida a partir de registros médicos de entrevistas personales. Se obtuvieron estadísticos descriptivos para variables continuas. Se realizaron pruebas estadísticas en función de la naturaleza de las variables. Resultados: Variables como el estado civil, el nivel educativo, la ocupación y el hábito de fumar mostraron diferencias dependiendo del sexo (p<0,05). El 82,3% de los que recibieron educación sobre salud perdieron peso en comparación con el 67,5% de los que perdieron peso y no la recibieron (p=0,004). Los medicamentos GLP1 y SGLT2 se recetaron con mayor frecuencia a las mujeres (p=0,048), mientras que los SGLT2 se prescribieron más en hombres (p=0,047). Los pacientes que tomaron GLP1, SGLT2 o ambos, independientemente del sexo, perdieron 3,1kg durante el estudio (EE: 0,60), mientras que aquellos que tomaron otros medicamentos perdieron 1,33kg (EE: 0,62). La diferencia media fue de 1,75kg (p=0,046). Conclusiones: Los diabéticos obesos que tomaron GLP1, SGLT2 o ambos tenían 2,5 veces más probabilidades de perder peso que aquellos que no los tomaron. Un estilo de vida saludable es fundamental para la pérdida de peso en pacientes diabéticos obesos.(AU)

RESUMO

AIMS: To determine the degree and factors related to non-insulin antidiabetic drug (NIAD) adherence in people with type 2 diabetes mellitus (DM2) treated in primary carecentres in Spain. METHODS: We did a cross-sectional study. During the study visit, variables related todifferent clinical characteristics, Adherence to Refills and Medications Scale Spanishversion (ARMS-e) and usage of NIAD were collected. We estimated the adherence toNIADs using the proportion of days covered (PDC) equation. RESULTS: In total, 515 participants were included in the study. The mean PDC ratio was70.6 ( ± 28.9), and 50.5% (260) were classified as good adherent (PDC ≥80). Good adherence was highest among users of metformin (67.3%) and lowest among the participants using thiazolidinedione (0.8%). The score for ARMS-e was higher in the poor adherence group. In the multivariable analysis, HbA1c and the use of GLP1-RA or SGLT-2i were negatively associated with good adherence (odds ratio [OR]: 0.67, 95% confidence interval [CI]: 0.54, 0.82, OR: 0.20, 95%CI: 0.08, 0.46; OR: 0.56, 95%CI: 0.35, 0.89, respectively). CONCLUSIONS: Adherence to NIADs observed in our study is far from optimal. HbA1c and ARMS-e items could be used as adherence indicators to encourage treatment changes to improve T2DM control.

RESUMO

INTRODUCTION: Studies on treatment adherence to glucose-lowering drugs among patients with type 2 diabetes (T2D) including concomitant treatment for other cardiovascular risk factors are scarce. We aimed to estimate the prevalence of good adherence to all medications used to control diabetes, hypertension and dyslipidemia and to analyse cardiometabolic control and its associated factors in T2D patients in the primary care (PC) setting. METHODS: Observational, retrospective study conducted in adult patients with T2D who were followed in the PC setting in Spain. Patients were classified as adherent in a particular category if the summary of the proportion of days covered (PDC) for a particular medication category was ≥80% and were considered globally adherent if the PDC was ≥80% for each of the 3 medication categories. RESULTS: A total of 457 evaluable patients were recruited, among which 321 patients (70.3%, 95% CI 65.8 to 74.4) were adherent to the three drug categories. The proportion of patients controlled for the 3 cardiometabolic risk factors was 31% according to the contemporary clinical practice guideline criteria, 58% according to investigator judgment and 36% when the objective for HbA1c was individualized. In a multivariate analysis, presenting comorbidities was associated with a lower likelihood of showing adequate control of dyslipidemia (odds ratio [OR] 0.25, 95% CI, 0.16-0.40) and the three cardiometabolic factors as a whole (OR 0.43, 95% CI 0.26-0.70). In a post hoc analysis, therapeutic inertia was found to be greater for dyslipidemia and hypertension than for T2D. CONCLUSIONS: Despite a relatively high adherence to all medications for treating diabetes, hypertension and dyslipidemia in patients with T2D in the PC setting in Spain, the control of cardiometabolic risk factors as a whole is far from optimal. This could be related, at least in part, to the high frequency of comorbidity of these patients.

RESUMO

We aimed to evaluate the experience of patients with type 2 diabetes (T2DM) with healthcare received in Spain. This was a retrospective, observational study in patients with T2DM cared for in primary healthcare (PHC) centers. A cross-sectional analysis of the patients' experience data was performed using the Instrument for the Evaluation of the Experience of Chronic Patients (IEXPAC). A total of 475 patients with T2DM were recruited from 36 PHC centers, of which 248 (52.2%) completed the IEXPAC questionnaire. The IEXPAC total mean score (range 0-10) was 7 points, with an average "new relational model" score of 2.5 points. The mean continuity of care score after hospital discharge was 6.2 points. The results showed that 8% of the patients always or almost always used the internet to check their medical history, appointments or other data from their healthcare service, and 15% responded that healthcare professionals always or almost always informed them of forums or other reliable internet sites to obtain information about their illness. The study results show that there is a wide margin for improvement in the experience of patients with T2DM with healthcare in Spain, especially regarding the information patients receive or can obtain.

RESUMO

OBJECTIVE: Hypothyroidism is the most common condition linked to a hormone deficiency, nevertheless data on its prevalence are scarce in Spain. For that reason, we have estimated its prevalence through the registration of patients who had used thyroid hormones in Andalusia (South Spain). METHODS: Data of patients who had withdrawn levothyroxine under the public system during 2014 from the base of the Andalusian Health Service were considered. Prevalence were calculated with confidence intervals of 95% for each management area, stratified by sex and age groups, and differences between them were evaluated. RESULTS: 321,368 people (98% older than 18 years and 83% female) were identified as levothyroxine users and a prevalence of hypothyroidism of 3.95% (95%CI:3.94-3.96) was estimated for the general population. The condition was more common in females, in the older 18 years 7.81% (95%CI:7.80 to 7.82) compared to males 1.75% (95%CI:1.73-1.77) with a ratio of 4.5-fold. It increases in the population of women older than 45 years, 10.32% (95%CI:10.30-0.32) and in the over 60 years 11.37% (95%CI: 11.35-11.40). The prevalence in adult women in the western provinces is 7.38% (95%CI:7.36-7.40), in the eastern provinces 8.59% (95%CI:8.57-8.62) and in coastal areas 6.70% (95%CI: 6.68-6.72) compared to the mountainous ones, which is 8.91% (95%CI:8.88-8.94). CONCLUSIONS: The results denote a high prevalence of hypothyroidism in the adult population of Andalusia compared to the nearby countries, with a clear increased associated with females and age. Furthermore, the prevalence of the illness presents also a geographically-related variability.

RESUMO

Fundamento: El hipotiroidismo es la condición más común ligada a un déficit hormonal. A pesar de ello existe una escasez de datos en España sobre su su prevalencia. El objetivo fue estimar la prevalencia en Andalucía a través del registro de pacientes que consumieron hormona tiroidea durante el año 2014. Método: Se recuperaron los datos de las personas que habían retirado de la farmacia levotiroxina con cargo al sistema público durante 2014 de la base de datos del Servicio Andaluz de Salud. Se calcularon las prevalencias con sus intervalos de confianza del 95% para cada Área de Gestión, estratificadas por sexo y grupos etarios. Resultados: Se identificaron 321.368 personas (98% mayores de 18 años y 83% mujeres) consumidoras de levotiroxina y se estimó una prevalencia de hipotiroidismo del 3,95% (IC95%: 3,943,96) para población general. La condición era más común en la mujer, en mayores de 18 años un 7,81% (IC95 7,80 a 7,82) comparada con el hombre 1,75% (IC95 1,73 a 1,77) con una razón de 4,5. Aumenta en la población de mujeres mayores de 45 años, 10,32% (IC95 10,30 a 10,32) y más en las mayores de 60 años 11,37% (IC95%: 11,35 a 11,40). La prevalencia en mujer adulta de las provincias occidentales fue 7,38% (IC95%: 7,36-7,40), en las orientales de 8,59% (IC95%: 8,57-8,62) y en las áreas costeras fue de 6,70% (IC95%: 6,68-6,72) frente a las montañosas que fue 8,91% (IC95%: 8,88-8,94). Conclusión: Los resultados indican una elevada prevalencia de hipotiroidismo en la población adulta de Andalucía, con un claro predominio de la mujer y un incremento con la edad. Además, la prevalencia de la enfermedad también presenta una importante variabilidad geográfica (AU)

RESUMO

BACKGROUND: Hypothyroidism (HT) is a common condition in clinical practice. There is a paucity of recent data on its prevalence in Spain, suggesting the need for an updated estimate and therefore the aim of this study was to determine its prevalence in the province of Cádiz. METHODS: We obtained data relative to medical prescriptions for group H03AA drugs issued in primary care centers attached to the Andalusian Health Service in the province of Cadiz in 2012. Prevalence was estimated on the basis of the defined daily dose (DDD), the prescribed daily dose (DDP) and treated patient records (TPR). We present the estimated prevalence and odds ratio by gender, with a confidence interval of 95%. RESULTS: Prevalence of HT in 2012 in the population aged 15 years and over in the province of Cadiz was 1.36% (CI95: 1.33%-1.38%) based on DDD; 2.60% (CI95: 2.54%-2.66%) based on DDP; and 3.10% (CI95: 2.85%-2.93%) based on TPR. Median age was 56 years (IQR: 43 to 68). Prevalence (TPR) by gender was 0.75% in men and 5.36% in women [OR 7.26 (CI95: 7.02-7.52)]. The greatest prevalence, 9.35%, was found in the group of women aged 51 to 70 years. CONCLUSIONS: Prevalence of HT in Cadiz is high, mainly affects women. Current prescribing systems allowed us to obtain TPRs, which have been shown to be a more valuable tool than DDDs for estimating HT prevalence.

RESUMO

Fundamentos: El hipotiroidismo (HT) es una patología frecuente en la práctica clínica diaria. No existen datos recientes sobre su prevalencia en España. El objetivo de este trabajo fue conocer su prevalencia en la provincia de Cádiz. Métodos: Se estudió el consumo del grupo terapéutico H03AA realizado en receta oficial por las unidades de Atención Primaria (AP) de Cádiz, durante el año 2012. La prevalencia se estimó mediante tres métodos: la Dosis Diaria Definida (DDD), la Dosis Diaria Prescrita (DDP) y el Registro Pacientes en Tratamiento (RPT). Los resultados se presentaron según sexo y edad con intervalos de confianza del 95%. Resultados: La prevalencia de HT durante 2012 en población mayor de 15 años de la provincia fue del 1,36% (IC95: 1,33%-1,38%) mediante DDD, del 2,60% (IC95: 2,54%-2,66%) mediante DDP y del 3,10% (IC95: 2,85%-2,93%) mediante RPT. La mediana de edad fue de 56 años (rango intercuartílico 43 a 68 años). La prevalencia (RPT) por sexo fue de 0,75% en hombres y 5,36% en mujeres [OR 7,26 (IC95: 7,02-7,52)], siendo del 9,35% la correspondiente a mujeres de 51 a 70 años. Conclusiones: El método de estimación por RPT demuestra ser una herramienta más válida que el método DDD para evaluar la prevalencia de HT. El HT muestra, en nuestra provincia una prevalencia elevada con mayor afectación del sexo femenino (AU)

RESUMO

BACKGROUND AND OBJECTIVES: Hyperuricemia is considered a feature of the metabolic syndrome (MS) despite serum uric acid (SUA) is not considered a diagnostic criterion. The main physiopathological disturbance leading to the increased SUA is not completely understood. PATIENTS AND METHOD: Descriptive study without drug intervention including 141 subjects (NCEP-ATPIII: 105 with MS and 36 without MS). Serum UA levels were compared in subjects with and without MS. The mechanism of the rise in SUA levels was assessed (overproduction or decreased renal excretion). The relation of SUA levels to the HOMA index was also evaluated. RESULTS: Subjects with MS showed significantly higher SUA levels (5.6 [1.6] vs 4.6 [1.7] mg/dl, p = 0.002), and lower urinary UA excretion than subjects without MS (UA clearance 3.60 [2.41] vs 4.65 [3.04] ml/min/m2, p = 0.049; excreted fraction of filtered UA 7.15 [4.72] vs 9.81 [6.78%], p = 0.045). Sex (male 6.1 [1.6] vs female 4.9 [1.6] mg/dl, p < 0.001), alcohol intake (drinkers 6.1 [1.8] vs non-drinkers 5.2 [1.6] mg/dl, p < 0.01), and MS (present 5.6 [1.6] absent 4.6 [1.7] mg/dl, p < 0.002), were significantly associated with SUA. In the multiple regression analysis, sex and MS were independently associated with SUA. CONCLUSIONS: This study demonstrates significantly higher SUA levels in subjects with MS. A decreased urinary UA excretion, instead of urate overproduction, was the leading mechanism to explain high SUA. Serum UA levels were not associated with the HOMA index.

RESUMO

Fundamento y objetivos: La hiperuricemia es una de las alteraciones características del síndrome metabólico (SM), aunque no incluida como criterio diagnóstico. No se conoce con exactitud el mecanismo que causa la elevación del urato sérico en el SM. Pacientes y método: Estudio transversal, sin intervención farmacológica, sobre 141 individuos (National Cholesterol Education Program Adult Treatment Panel III: 105 con SM y 36 sin SM). Se comparan los valores de urato sérico entre individuos con y sin SM, y se analiza si la elevación del urato sérico se asocia a infraexcreción renal o sobreproducción. Se determina la asociación del urato sérico a índice HOMA. Resultados: El grupo con SM presentó valores de urato sérico significativamente más elevados (media [DE] 5,6 [1,6] frente a 4,6 [1,7] mg/dl, p = 0,002), y menor excreción urinaria (aclaramiento de ácido úrico 3,60 [2,41] frente a 4,65 [3,04] ml/min/m2, p = 0,049; fracción excretada del ácido úrico filtrado 7,15 [4,72] frente a 9,81 [6,78]%, p = 0,045). Las variables asociadas con los valores de urato sérico fueron el sexo (media de urato sérico en varón 6,1 [1,6] frente a mujer 4,9 [1,6] mg/dl, p < 0,001), el alcohol (bebedores 6,1 [1,8] frente a no bebedores 5,2 [1,6] mg/dl, p < 0,01), y el SM (presente 5,6 [1,6] frente a ausente 4,6 [1,7] mg/dl, p < 0,002). En el análisis multivariante, sólo el sexo y el SM se asociaron independientemente con los valores de urato sérico. Conclusiones: El presente estudio muestra unos valores de urato sérico significativamente más elevados entre individuos con SM, relacionado a su vez con una infraexcreción renal de uratos. No se observó asociación significativa de los valores de urato sérico con el índice HOMA

The mechanism of the rise in SUA levels was assessed (overproduction or decreased renal excretion). The relation of SUA levels to the HOMA index was also evaluated. Results: Subjects with MS showed significantly higher SUA levels (5.6 [1.6] vs 4.6 [1.7] mg/dl, p = 0.002), and lower urinary UA excretion than subjects without MS (UA clearance 3.60 [2.41] vs 4.65 [3.04] ml/min/m2, p = 0.049; excreted fraction of filtered UA 7.15 [4.72] vs 9.81 [6.78%], p = 0.045). Sex (male 6.1 [1.6] vs female 4.9 [1.6] mg/dl, p < 0.001), alcohol intake (drinkers 6.1 [1.8] vs non-drinkers 5.2 [1.6] mg/dl, p < 0.01), and MS (present 5.6 [1.6] absent 4.6 [1.7] mg/dl, p < 0.002), were significantly associated with SUA. In the multiple regression analysis, sex and MS were independently associated with SUA. Conclusions: This study demonstrates significantly higher SUA levels in subjects with MS. A decreased urinary UA excretion, instead of urate overproduction, was the leading mechanism to explain high SUA. Serum UA levels were not associated with the HOMA index
