Hypoglycemia during hyperosmolar hyperglycemic crises is associated with long-term mortality.

BACKGROUND: Previous research has indicated that hypoglycemia during hospitalization is a predictor of unfavorable outcomes in patients with diabetes. However, no studies have examined the long-term impact of hypoglycemia in adults admitted for hyperglycemic crises. The study was aimed to investigate the long-term implications of hypoglycemia during hyperosmolar hyperglycemic crises, particularly in terms of all-cause mortality. METHODS: This retrospective cohort study included 170 patients (82 men [48.2%], median age 72 years) admitted to a university hospital for hyperosmolar hyperglycemic crises, including pure hyperosmolar hyperglycemic states and hyperosmolar diabetic ketoacidoses. We separately investigated the prognostic significance of hypoglycemia on mortality during the initial intravenous insulin therapy phase and during the later subcutaneous insulin therapy phase, both during hospitalization and in the long term (median follow-up, 652 days; range 2-3460 days). RESULTS: Both hypoglycemia during the initial intravenous insulin therapy phase (observed in 26.5% of patients) and hypoglycemia during the later subcutaneous insulin therapy phase (observed in 52.7% of patients) were associated with long-term mortality. After adjusting for potential confounders, hypoglycemia during the initial intravenous insulin therapy phase remained associated with mortality (hazard ratio 2.10, 95% CI 1.27-3.46, p = 0.004). CONCLUSIONS: Hypoglycemia during hyperosmolar hyperglycemic crises is a marker of long-term mortality, especially when it occurs during the initial intravenous insulin therapy phase.

Differences between GH and PRL co-secreting and GH-secreting pituitary adenomas. A series of 604 cases.

PURPOSE: To evaluate differences in clinical presentation and in surgical outcomes between growth hormone-secreting pituitary adenomas (GH-PAs) and GH and prolactin co-secreting pituitary adenomas (GH&PRL-PAs). METHODS: Multicenter retrospective study of 604 patients with acromegaly submitted to pituitary surgery. Patients were classified into two groups according to serum PRL levels at diagnosis and immunohistochemistry (IHC) for PRL: a) GH&PRL-PAs when PRL levels were above the upper limit of normal and IHC for GH and PRL was positive or PRL levels were >100ng/and PRL IHC was not available (n=130) and b) GH-PAs who did not meet the previously mentioned criteria (n=474). RESULTS: GH&PRL-PAs represented 21.5% (n=130) of patients with acromegaly. The mean age at diagnosis was lower in GH&PRL-PAs than in GH-PAs (P<0.001). GH&PRL-PAs were more frequently macroadenomas (90.6% vs. 77.4%, P=0.001) and tended to be more invasive (33.6% vs. 24.7%, P=0.057) than GH-PAs. Furthermore, they had presurgical hypopituitarism more frequently (OR 2.8, 95% CI 1.83-4.38). IGF-1 upper limit of normality (ULN) levels at diagnosis were lower in patients with GH&PRL-PAs (median 2.4 [IQR 1.73-3.29] vs. 2.7 [IQR 1.91-3.67], P=0.023). There were no differences in the immediate (41.1% vs 43.3%, P=0.659) or long-term post-surgical acromegaly biochemical cure rate (53.5% vs. 53.1%, P=0.936) between groups. However, there was a higher incidence of permanent arginine-vasopressin deficiency (AVP-D) (7.3% vs. 2.4%, P=0.011) in GH&PRL-PAs patients. CONCLUSIONS: GH&PRL-PAs are responsible for 20% of acromegaly cases. These tumors are more invasive, larger and cause hypopituitarism more frequently than GH-PAs and are diagnosed at an earlier age. The biochemical cure rate is similar between both groups, but patients with GH&PRL-PAs tend to develop permanent postsurgical AVP-D more frequently.

Hypoglycemia in patients with type 2 diabetes mellitus during hospitalization: associated factors and prognostic value.

BACKGROUND: The risk factors for hypoglycemia during hospital admission and its consequences in patients with diabetes are not entirely known. The present study aimed to investigate the risk factors for hypoglycemia, as well as the potential implications of hypoglycemia in patients with type 2 diabetes mellitus admitted to the hospital. METHODS: This retrospective cohort study included 324 patients (214 [66.0%] men; median age 70 years, range 34-95 years) with type 2 diabetes admitted to a university hospital who were consulted the Endocrinology Department for glycemic control during a 12-month period. We investigated the potential role of demographic factors, metabolic factors, therapy, and comorbidities on the development of in-hospital hypoglycemia. We explored the prognostic value of hypoglycemia on mortality (both in-hospital and in the long-term), hospital readmission in the following year, and metabolic control (HbA1c value) after discharge (median follow-up, 886 days; range 19-1255 days). RESULTS: Hypoglycemia occurred in 154 (47.5%) patients during their hospitalization and was associated with advanced age, previous insulin therapy, higher Charlson Comorbidity Index, lower body mass index and lower baseline HbA1c values. Hypoglycemia was associated with greater in-hospital and long-term mortality, longer hospital stays, higher readmission rates, and poorer metabolic control after discharge. These negative consequences of hypoglycemia were more frequent in patients with severe (≤ 55 mg/dL) hypoglycemia and in patients who had hypoglycemia during a greater percentage of hospitalization days. CONCLUSIONS: Hypoglycemia during hospital admission is a marker of a poor prognosis in patients with type 2 diabetes.

Continuous glucose monitoring alarms in adults with type 1 diabetes: user characteristics and the impact of hypoglycemia and hyperglycemia alarm thresholds on glycemic control.

BACKGROUND: Few studies have evaluated the implications of the alarm thresholds of continuous glucose monitoring systems for individuals with diabetes. The present study aimed to investigate the influence of hypoglycemia and hyperglycemia alarm thresholds on glycemic control in adults with type 1 diabetes and the characteristics of patients who use these alarms more frequently. METHODS: This observational cross-sectional study included 873 users of the FreeStyle Libre 2 system (501 men, median age 48 years, range 18-90 years) with type 1 diabetes from a single center. We investigated the role of demographic and metabolic factors on the use of the alarms and the impact of hypoglycemia and hyperglycemia alarms and their thresholds on glycemic control. RESULTS: Alarm users were older than non-users (median age 49 years versus 43 years, respectively; p<0.001). The hypoglycemia alarms were set by 76.1% of women and by 69.1% of men (p=0.022). The hypoglycemia alarms reduced hypoglycemia features and glucose variability, although at the expense of shorter time in range. The higher the hypoglycemia alarm threshold, the greater these effects. The hyperglycemia alarms were effective in reducing hyperglycemia and lowering the glucose management indicator, although at the expense of a greater tendency to hypoglycemia. The lower the hyperglycemia alarm threshold, the greater these effects. CONCLUSIONS: Continuous glucose monitoring alarms contribute to better glycemic control. However, hypoglycemia and hyperglycemia alarms have advantages and disadvantages. Adults with type 1 diabetes should explore, under medical supervision, which alarm thresholds will best help them achieve their individual glycemic goals.

[Cetoacidosis diabética al diagnóstico de diabetes mellitus tipo 1 en Asturias entre 2011 y 2020: influencia de la duración de los síntomas en la prevalencia de cetoacidosis y en la pérdida de peso.] / Diabetic ketoacidosis at diagnosis of type 1 diabetes in Asturias (Spain) between 2011 and 2020: influence of symptom duration on prevalence of ketoacidosis and weight loss.

OBJECTIVE: Diabetic ketoacidosis (DKA) is a serious complication that usually occurs at diagnosis of type 1 diabetes mellitus (T1D). However, the prevalence of DKA at diagnosis of T1D is heterogeneous in different regions of the world. The aim of this study was to determine the prevalence of DKA at diagnosis of T1D in Asturias. METHODS: This study included all patients under nineteen years of age diagnosed with T1D in Asturias between 2011 and 2020. Retrospective review of medical records was performed to analyse DKA and other characteristics at diagnosis. A log binary regression model was constructed to obtain an estimate of the prevalence ratio of DKA to diagnosis in the years studied. RESULTS: A total of 267 people were diagnosed with a mean age of 9.85±4.46 years. The prevalence of DKA at diagnosis during this period was 38.63%. There was an increasing trend, with a prevalence ratio over the years studied of 1.015 (95%CI: 0.96-1.07; p=0.61). Duration of symptoms before diagnosis was 4.57±7.64 weeks. Weight loss was 7.56±7.26%, being more than 10% of previous weight in almost half of the patients who loosed weight. There was a positive relationship between symptoms duration and prevalence of DKA and between time to diagnosis and weight loss. CONCLUSIONS: Asturias has a high prevalence of DKA at diagnosis of T1D, slightly higher than observed in other studies at national level and higher than in other similar countries, with a tendency to increase. Delayed diagnosis is a key factor in the prevalence of DKA and weight loss. Thus, health actions are needed for the early detection of T1D to avoid DKA at diagnosis.

OBJETIVO: La cetoacidosis diabética (CAD) es una complicación grave que puede producirse al diagnóstico de la diabetes mellitus tipo 1 (DM1). La prevalencia de CAD al diagnóstico de DM1 es desigual en las distintas regiones del mundo. El objetivo de este estudio fue conocer la prevalencia de CAD al diagnóstico de DM1 en Asturias. METODOS: Se incluyeron los pacientes menores de diecinueve años diagnosticados de DM1 en Asturias entre 2011 y 2020. Mediante revisión de historia clínica se analizó la prevalencia de CAD así como otras características al diagnóstico. Se construyó un modelo de regresión log binaria para obtener una estimación de la razón de prevalencia de CAD al diagnóstico en los años estudiados. RESULTADOS: Se diagnosticaron 267 personas con edad media de 9,85±4,46 años. La prevalencia de CAD al diagnóstico fue del 38,63%. Se apreció una tendencia al aumento, con una razón de prevalencia en los años estudiados de 1,015 (IC95%:0,96-1,07; p=0,61). La duración de los síntomas hasta el diagnóstico fue de 4,57±7,64 semanas. La pérdida de peso fue de 7,56±7,26%, siendo superior al 10% en casi la mitad de los pacientes que perdieron peso. Se apreció relación entre la duración de los síntomas y la prevalencia de CAD, y entre el tiempo de evolución y la pérdida de peso. CONCLUSIONES: Asturias presenta una alta prevalencia de CAD al diagnóstico de DM1, levemente superior a otros estudios a nivel nacional y superior a otros países de nuestro entorno, con tendencia al aumento. El retraso diagnóstico es clave en la prevalencia de CAD y en la pérdida de peso. Son necesarias actuaciones sanitarias para la detección precoz de la DM1.

Survey of Spanish hospitals on diabetes care resources.

INTRODUCTION: The quality of diabetes care varies from region to region. The objective of this study is to analyze the characteristics of care in different hospitals in Spain through a specific survey assessing different aspects of care for both children and adults. MATERIALS AND METHODS: Cross-sectional observational voluntary survey study, sent to the heads of the Endocrinology and Pediatric Endocrinology Departments or Units in public hospitals with more than 150 beds, during the first semester of 2021. A total of 105 responses were obtained, 55.5% of the 189 requested, which corresponded to a population served of 31,782,409 people, representing almost 80% of the total population served. RESULTS: Patients with diabetes under 15 years of age are cared for by Pediatric Departments, but only 58% of them have a specific Diabetes Education Unit for children, and in 72% of the cases, there is one single nurse dedicated to these tasks, and not always full-time. Those over 15 years of age are attended by specialists in Endocrinology and Nutrition in 94.3 % of hospitals. There are Therapeutic Education Units in Diabetes in practically all hospitals (94.3%). However, Diabetes Day Hospitals exist in only 32 centres and cover 40.3% of the population, since in 22 provinces there are none. Virtual and telematic consultations, as well as retinography, are available in more than 70% of cases, but access to a Diabetic Foot Unit only in 54% of centres. Monographic technological consultations on diabetes have become widespread, but access to mental health specialists with diabetes training remains limited (24% of centres), and interdisciplinary (32%) or interlevel (12%) committees are very scarce. CONCLUSION: Diabetes care in Spain shows great variability from one region to another, and some deficiencies have been detected that affect a large part of the population, such as access to Diabetic Foot Units, as well as mental health specialists with specific training. The presence of multidisciplinary and mixed committees between levels of care remains scarce.

Reclassification of type 2 diabetes to type 1 diabetes in Asturias (Spain) between 2011 and 2020.

BACKGROUND: Differentiating between type 1 diabetes (T1D) and type 2 diabetes (T2D) can be difficult in adults. The aim of this study was to determine the frequency of diagnostic reclassification from T2D to T1D, the characteristics of the patients and the impact on the management of the disease. METHODS: Observational and descriptive study including patients diagnosed with T1D in Asturias (Spain) between 2011 and 2020 who had been considered as T2D for at least 12 months. RESULTS: A total of 205 patients were included, representing 45.3% of those diagnosed with T1D over 30 years of age. Median time of evolution as T2D was 7,8 years. The age was 59.1 ± 12.9 years. BMI was > 25 kg/m2 in 46.8% of patients. HbA1c was 9.1 ± 2.1%, 77 ± 22 mmol/mol, and 56.5% were using insulin. Pancreatic antibodies were present in 95.5%, the most frequent being GAD, 82.6%. At 6 months, basal insulin use increased from 46.9 to 86.3%, and HbA1c decreased, 9.2 ± 2.0%vs7.7 ± 1.2%, 77 ± 22vs60 ± 13 mmol/mol; p < 0.0001. CONCLUSIONS: Diagnosis as T2D in patients with T1D in adults is common. Age, BMI, insulin use and other clinical features are not definitely discriminatory. GAD is the antibody of choice in case of diagnostic suspect. Reclassification has important implications for metabolic control.

Iodine status in pregnant women in northern Spain. Effect of iodised salt and iodine supplements on thyroid function.

INTRODUCTION: Iodine deficiency is linked to thyroid dysfunction, particularly in pregnant women. The objective of this study was to ascertain the iodine levels of women in the second trimester of pregnancy, analysing the influence of iodine ingestion on urinary iodine concentration (UIC) and maternal thyroid function. METHODS: A prospective observational study of pregnant women from Health Area IV of Asturias (northern Spain) recruited before 13 weeks of gestation between May and June 2017. A questionnaire on iodine intake was completed at the first visit, and urine and serum samples were collected at baseline and again during the second trimester. UIC, thyroid stimulating hormone (TSH) and free thyroxine (FT4) obtained in the second trimester of gestation were analysed and related to iodine intake. Thyroid autoimmunity was also analysed in half of the pregnant women at baseline. RESULTS: A total of 241 pregnant women were studied. Of these, 56.7% used iodised salt, 46.7% consumed ≥2 servings of dairy products daily and 88.1% took iodine supplements. Median UIC was 191µg/l (135.3-294µg/l), with 68.1% of the women having UIC ≥150µg/l. Only iodised salt consumption provided protection against iodine deficiency (odds ratio 0.35 [0.20-0.63], p=0.001). In women with no autoimmune thyroid disease (n=88), mean levels of TSH were lower in those that consumed iodised salt than in those that did not (respectively, 2.08±0.89mIU/l vs. 2.56±1.02mIU/l, p=0.025). In women with autoimmune thyroid disease (n=30), mean levels of TSH were higher in those that took iodine supplements than in those that did not (respectively, 2.97±1.25mIU/l vs. 1.16±0.41mIU/l, p=0.002). CONCLUSIONS: The pregnant women studied from Health Area IV in Asturias maintain adequate nutritional iodine status in the second trimester of gestation. In our sample, only the consumption of iodised salt was associated with adequate iodine nutrition, without affecting maternal thyroid function. Most of the women used iodine supplements, which was linked to higher levels of TSH in pregnant women with autoimmune thyroid disease.

Mortality in Acromegaly Diagnosed in Older Individuals in Spain Is Higher in Women Compared to the General Spanish Population.

CONTEXT: There are no data on mortality of acromegaly diagnosed in older individuals. OBJECTIVE: This work aimed to compare clinical characteristics, growth hormone-related comorbidities, therapeutic approaches, and mortality rate of patients diagnosed before or after 2010 and to assess overall mortality rate compared with the general Spanish population. METHODS: A retrospective evaluation was conducted among Spanish tertiary care centers of 118 patients diagnosed with acromegaly at age 65 or older. Kaplan-Meier curves were constructed to trace survival, and Cox proportional hazard models were used to assess the risk factors associated with mortality. We also compared mortality with that of the Spanish population by using age- and sex-adjusted standardized mortality ratios (SMRs). RESULTS: No differences were found in first-line treatment or biochemical control, between both periods except for faster biochemical control after 2010. Twenty-nine (24.6%) patients died, without differences between groups, and had a median of follow-up 8.6 years (103, [72.3] months). Overall SMR was 1.02 (95% CI, 0.57-1.54), (0.60; 95% CI, 0.35-1.06) for men and (1.80; 95% CI, 1.07-2.94) for women. The most common cause of death was cardiovascular disease (CVD). CONCLUSION: The mortality in patients with acromegaly diagnosed in older individuals was no different between both periods, and there was no overall SMR difference compared with the general Spanish population. However, the SMR was higher in women. As CVD is the leading cause of mortality, it seems advisable to initiate an intense CVD protective treatment as soon as acromegaly is diagnosed, particularly in women, in addition to tight acromegaly control to prevent excess mortality.

Incidence of type 1 diabetes mellitus in Asturias (Spain) between 2011 and 2020.

INTRODUCTION: Type 1 diabetes mellitus (DM1) is a chronic disease with important socio-health repercussions that requires epidemiological information for proper health management. The aim of this study was to determine the incidence of DM1 in Asturias between 2011-2020. METHODS: Descriptive study which included diagnoses of DM1 in Asturias between 2011-2020 captured as a primary source by reviewing the register of pancreatic autoimmunity analysis. Incidence rates were estimated, expressed per 100,000 population-years of risk by age group, sex, and health area. RESULTS: A total of 815 patients were diagnosed, 53.13% men. The mean age was 34.32±22.07 years; 9.85±4.46 in children under 19 years of age (10.48±4.45 in males and 9.00±4.36 in females). Of the diagnoses, 55.34% occurred at an age over 30 years. The incidence was 7.82 (7.29-8.37); 19.65 (17.17-22.39) in under 15s and 12.84 (11.73-14.03) in under 40s. The maximum incidence peak was between 10-14 years, both in males 31.16 (23.89-39.95) and in females 21.72 (15.59-29.47). There was no significant increase in incidence over the years studied. CONCLUSIONS: Asturias has a high incidence of DM1. In our study no earlier age at diagnosis was observed or an increase in incidence. Compared to previous studies, the increase in incidence is most likely due to an improvement in data capture, not to a real increase in incidence. A high percentage of diagnoses occur in adulthood.

miR-24-3p and Body Mass Index as Type 2 Diabetes Risk Factors in Spanish Women 15 Years after Gestational Diabetes Mellitus Diagnosis.

Gestational diabetes mellitus (GDM) is defined as any degree of glucose intolerance that is diagnosed for the first time during pregnancy. The objective of this study is to know the glucose tolerance status after 15 years of pregnancy in patients diagnosed with gestational diabetes and to assess the long-term effect of GDM on the circulating miRNA profile of these women. To answer these, 30 randomly selected women diagnosed with GDM during 2005-2006 were included in the study, and glucose tolerance was measured using the National Diabetes Data Group criteria. Additionally, four miRNAs (hsa-miR-1-3p, hsa-miR-24-3p, hsa-miR-329-3p, hsa-miR-543) were selected for their analysis in the plasma of women 15 years after the diagnosis of GDM. In our study we discovered that, fifteen years after the diagnosis of GDM, 50% of women have some degree of glucose intolerance directly related to body weight and body mass index during pregnancy. Dysglycemic women also showed a significantly increased level of circulating hsa-miR-24-3p. Thus, we can conclude that initial weight and BMI, together with circulating expression levels of hsa-miR-24-3p, could be good predictors of the future development of dysglycemia in women with a previous diagnosis of GDM.

Efficacy of a Connected Insulin Pen Cap in People With Noncontrolled Type 1 Diabetes: A Multicenter Randomized Clinical Trial.

OBJECTIVE: To assess the efficacy of the insulin pen cap Insulclock on improving glycemic control, treatment adherence, and user satisfaction in people with type 1 diabetes. RESEARCH DESIGN AND METHODS: This multicenter, open-label, randomized controlled trial comprised a 4-week run-in phase and a 6-week double-arm phase in which participants were randomly assigned into an active or masked mode. RESULTS: Fifty-five participants were evaluable (active group, n = 26, masked group, n = 29). The increase in time in range was higher in the active versus masked group (5.2% vs. -0.8%; P = 0.016). The active group showed a higher reduction in mean glucose, glucose management indicator, time above range, and high blood glucose index. On-time insulin doses increased in the active group and decreased in the masked group. CONCLUSIONS: Insulclock system use was associated with improved glycemic control, glycemic variability, hyperglycemia risk, and treatment adherence in people with uncontrolled type 1 diabetes.

TSH neonatal como marcador del estado de nutrición de yodo. Influencia de la yoduria y la función tiroidea maternas sobre la TSH neonatal / Neonatal TSH as a marker of iodine nutrition status. Effect of maternal ioduria and thyroid function on neonatal TSH

Introducción: La TSH neonatal (TSHn) es un marcador de nutrición de yodo en la población. La OMS relaciona una prevalencia<3% de TSHn>5mUI/L, obtenida a partir de las 72h del nacimiento, con un adecuado estado nutricional de yodo. El objetivo de este estudio es conocer la prevalencia de TSHn>5mUI/L en una población yodosuficiente y su relación con factores maternos, neonatales y obstétricos. Materiales y métodos: Se reclutaron 243 gestantes entre mayo-junio de 2017 en nuestra área sanitaria. Se realizó un cuestionario sobre consumo de yodo y determinación de yoduria, función y autoinmunidad tiroideas en el primer trimestre de gestación. Se analizó la TSHn entre 48-72h del nacimiento, así como otros factores obstétricos y neonatales. Resultados: La TSHn media fue 2,43±1,68mUI/L, con un 7,8% de neonatos con TSHn>5mUI/L. La TSHn más elevada pertenecía a los neonatos de madres con yodurias insuficientes (p=0,021) o con TSH>2,5mUI/L, tanto en autoinmunidad tiroidea negativa (p=0,049) como positiva (p=0,006). La yoduria materna<150μg/L fue un factor de riesgo de TSHn>5mUI/L (3,70 [1,06-14,60], p=0,046), mientras que el peso neonatal ≥2500g fue un factor protector (0,14 [0,02-1,00], p=0,038). Conclusiones: La prevalencia de TSHn>5mUI/L en nuestra área sanitaria fue elevada, según las recomendaciones de la OMS. Se asoció el déficit de yodo materno con mayor riesgo de TSHn>5mUI/L. Dado que en la actualidad la determinación de la TSHn se realiza antes de las 72h del nacimiento, precisamos de nuevos puntos de corte para continuar empleando la TSHn como marcador de nutrición de yodo.

Introduction: Neonatal thyroid stimulating hormone (nTSH) is a marker of iodine nutrition status in the population. The WHO considers a prevalence of less than 3% of nTSH levels greater than 5mIU/L in samples obtained within 72h from birth indicative of iodine sufficiency. The aim of this study was to determine the prevalence of nTSH levels greater than 5mIU/L in an iodine-sufficient population and its association with maternal, neonatal and obstetric factors. Materials and methods: A total of 243 pregnant women were recruited between May and June 2017 in our health area. A questionnaire of iodine intake was administered, in addition to determination of ioduria, thyroid function and autoimmunity in the first trimester of gestation. We analysed nTSH levels in samples collected between 48 and 72h post birth and other obstetric and neonatal factors. Results: The mean nTSH level (standard deviation) was 2.43 (1.68mIU/L), with 7.8% of neonates having levels greater than 5mIU/L. The highest nTSH levels corresponded to neonates of mothers with insufficient ioduria (p=.021) or TSH levels greater than 2.5mIU/L, in both the case of negative (p=0.049) and positive (p=0.006) thyroid autoimmunity results. Maternal ioduria greater than 150μg/L was a risk factor for nTSH levels greater than 5mIU/L (3.70 [1.06–14.60]; p=0.046), while a neonatal weight of 2500g or greater was a protective factor (0.14 [0.02–1.00]; p=0.038). Conclusions: The prevalence of nTSH levels greater than 5mIU/L in our health area was high based on the WHO recommendations. Maternal iodine deficiency was associated with a higher risk of nTSH levels less than 5mIU/L. Given that nTSH is currently measured before 72h post birth, we need new cut-off points to keep on using nTSH as a marker of iodine nutritional status. (AU)

Neonatal TSH as a marker of iodine nutrition status. Effect of maternal ioduria and thyroid function on neonatal TSH.

INTRODUCTION: Neonatal thyroid stimulating hormone (nTSH) is a marker of iodine nutrition status in the population. The WHO considers a prevalence of less than 3% of nTSH levels greater than 5 mIU/L in samples obtained within 72h from birth indicative of iodine sufficiency. The aim of this study was to determine the prevalence of nTSH levels greater than 5 mIU/L in an iodine-sufficient population and its association with maternal, neonatal and obstetric factors. MATERIALS AND METHODS: A total of 243 pregnant women were recruited between May and June 2017 in our health area. A questionnaire of iodine intake was administered, in addition to determination of ioduria, thyroid function and autoimmunity in the first trimester of gestation. We analysed nTSH levels in samples collected between 48 and 72h post birth and other obstetric and neonatal factors. RESULTS: The mean nTSH level (standard deviation) was 2.43 (1.68 mIU/L), with 7.8% of neonates having levels greater than 5 mIU/L. The highest nTSH levels corresponded to neonates of mothers with insufficient ioduria (P = 0.021) or TSH levels greater than 2.5 mIU/L, in both the case of negative (P = 0.049) and positive (P = 0.006) thyroid autoimmunity results. Maternal ioduria less than 150 µg/L was a risk factor for nTSH levels greater than 5 mIU/L (3.70 [1.06-14.60]; P = 0.046), while a neonatal weight of 2500 g or greater was a protective factor (0.14 [0.02-1.00]; P = 0.038). CONCLUSIONS: The prevalence of nTSH levels greater than 5 mIU/L in our health area was high based on the WHO recommendations. Maternal iodine deficiency was associated with a higher risk of nTSH levels greater than 5 mIU/L. Given that nTSH is currently measured before 72h post birth, we need new cut-off points to keep on using nTSH as a marker of iodine nutritional status.

Factors associated with therapeutic response in acromegaly diagnosed in the elderly in Spain.

Context: Some reports suggest that acromegaly in elderly patients has a more benign clinical behavior and could have a better response to first-generation long-acting somatostatin receptor ligands (SRL). However, there is no specific therapeutic protocol for this special subgroup of patients. Objective: This study aimed at identifying predictors of response to SRL in elderly patients. Design: Multicentric retrospective nationwide study of patients diagnosed with acromegaly at or over the age of 65 years. Results: One-hundred and eighteen patients (34 men, 84 women, mean age at diagnosis 71.7 ± 5.4 years old) were included. Basal insulin-like growth factor type 1 (IGF-1) above the upper limit of normal (ULN) and growth hormone (GH) levels (mean ± SD) were 2.7 ± 1.4 and 11.0 ± 11.9 ng/ml, respectively. The mean maximal tumor diameter was 12.3 ± 6.4 mm, and up to 68.6% were macroadenoma. Seventy-two out of 118 patients (61.0%) underwent surgery as primary treatment. One-third of patients required first-line medical treatment due to a rejection of surgical treatment or non-suitability because of high surgical risk. After first-line surgery, 45/72 (63.9%) were in disease remission, and 16/34 (46.7%) of those treated with SRL had controlled disease. Patients with basal GH at diagnosis ≤6 ng/ml had lower IGF-1 levels and had smaller tumors, and more patients in this group reached control with SRL (72.7% vs. 33.3%; p < 0.04) [OR: 21.3, IC: 95% (2.4-91.1)], while male patients had a worse response [OR: 0.09, IC 95% (0.01-0.75)]. The predictive model curve obtained for SRL response showed an AUC of 0.82 CI (0.71-0.94). Conclusions: The most frequent phenotype in newly diagnosed acromegaly in the elderly includes small adenomas and moderately high IGF-1 levels. GH at diagnosis ≤6 ng/ml and female gender, but not age per se, were associated with a greater chance of response to SRL.

Correlation between glucose measurement parameters of continuous flash monitoring and HbA1c. Real life experience in Asturias.

INTRODUCTION: Despite continuous glucose monitoring having been proven useful in patients with type 1 diabetes mellitus, A1C remains the gold standard for assessing disease management. MATERIAL AND METHODS: Descriptive, retrospective study which included 252 patients, 40.5% male, mean age 44.91±14.57 years, mean duration of diabetes 22.21±13.12 years, 88.1% on basal-bolus insulin therapy and 11.9% users of continuous subcutaneous insulin infusion. Glucose measurement, analytical and anthropometric data were obtained. RESULTS: The mean time in range was 60.18±15.60% and was associated with A1C after adjusting for age, gender, duration of diabetes, BMI, insulin regimen, %CV and time below range (ß: -0.548; p<0.01). The glucose management indicator (GMI) was 7.19±0.69% and was also associated with A1C (ß: 0.957; p<0.01) regardless of age, gender, duration of diabetes, BMI, insulin treatment, %CV and time in range. The average difference between A1C and GMI was 0.17±0.65% (-2.70-3.40%), being higher as A1C increased, in a linear and significant manner, without being influenced by the duration of diabetes or CV. CONCLUSIONS: Although we found a positive correlation between continuous glucose monitoring glucose measurement parameters and A1C, there is still not enough evidence to replace one parameter with another.
