Bone metastases from differentiated thyroid cancer: characteristics and prognostic factors in a multicenter series.

Objective: The aim of this study is to describe the characteristics, survival and prognostic factors of a cohort of patients with bone metastases (BMs) from differentiated thyroid carcinoma (DTC). Methods: This was a multicenter retrospective observational study including patients diagnosed with BMs from DTC between 1980 and 2021. A Cox regression was performed to study prognostic factors for 5- and 10-year survival. Kaplan-Meier and log-rank tests were performed for the survival analysis and comparison between groups. Results: Sixty-three patients were evaluated. Median follow-up from BM diagnosis was 35 (15-68) months. About 30 (48.4%) patients presented with synchronous BMs. Regarding histology, 38 (60.3%) had the papillary variant. BMs were multiple in 32 (50.8%) patients. The most frequent location was the spine (60.3%). Other metastases were present in 77.8%, mainly pulmonary (69.8%). Concerning treatment, 54 (85.9%) patients received I131, with BM uptake in 31 (49.2%) and 25 (39.7%) received treatment with multikinase inhibitors. Regarding complications, 34 (54%) patients had skeletal-related events, 34 (54%) died and 5- and 10-year overall survival was 42.4% and 20.4%, respectively. Significant prognostic factors in the multivariate analysis were the presence of lymph node involvement (hazard ratio (HR): 2.916; 95% confidence interval (CI): 1.013-8.391; P = 0.047) and treatment with I131 (HR 0.214 (95% CI 0.069-0.665); P = 0.008) at 5 years, the presence of other metastases (HR 6.844. 95% CI 1.017-46.05; P = 0.048) and treatment with I131 (HR 0.23 (95% CI 0.058-0.913); P = 0.037) at 10 years. Conclusions: Our study reflects the management of patients with bone metastases from differentiated thyroid carcinoma in real clinical practice in several centers in southern Spain. Overall survival at 5 and 10 years was lower in patients who were not treated with I131, had nodal involvement and/or had other metastases.

Spanish Consensus on the Use of Intermittently Scanned Continuous Glucose Monitoring in the Management of Patients With Insulin Therapy: The MONITOR Project.

BACKGROUND: Continuous glucose monitoring (CGM) systems are increasingly being adopted as an alternative or adjunct to self-monitoring of blood glucose (SMBG) by patients receiving insulin therapy. However, the available evidence on the role of intermittently scanned CGM or flash CGM (isCGM) remains limited. This consensus aims to evaluate the degree of agreement among Spanish experts on the role of isCGM in the evaluation of glycemic variability, reduction of glycosylated hemoglobin (HbA1c) levels, and selection and adjustment of insulin therapy. METHODS: Delphi methodology was used to achieve consensus in two survey rounds. A total of 431 Spanish endocrinologists participated in the first round of a 34-item questionnaire survey on isCGM and 427 participated in the second round. Any disagreement was resolved in round 2. RESULTS: Consensus was reached for 32 statements, and four items were ultimately agreed upon SMBG after round 2. There was a high degree of consensus that isCGM helps to evaluate glycemic variability, improves HbA1c levels, and can guide therapeutic changes in type 1 diabetes patients. However, there was no consensus on the routine use of the interquartile range to evaluate glycemic variability or the selection of HbA1c as the main parameter for monitoring glycemic control. CONCLUSIONS: Most Spanish experts believe that the isCGM system is appropriate for: (1) identifying glycemic variability and facilitating its management, (2) evaluating hyperglycemia as a complement of HbA1c levels, and (3) guiding therapeutic decisions on insulin selection and dosing. The isCGM system is a useful tool for patients and health care professionals to improve glycemic control in insulin-dependent diabetes.

Efficacy of Low-Dose Radioiodine Ablation in Low- and Intermediate-Risk Differentiated Thyroid Cancer: A Retrospective Comparative Analysis.

(1) Background-low-dose radioiodine ablation is an accepted strategy for the treatment of low- and intermediate-risk thyroid carcinomas, although there is no international consensus. The aim of this study is to describe the clinical experience with low-dose radioiodine ablation in patients with low- and intermediate-risk thyroid cancer compared to high-dose ablation. (2) Methods-174 patients with low- and intermediate-risk thyroid cancer, 90 treated with low-dose ablation and 84 treated with high-dose ablation, were included. The primary endpoint was response to treatment one year after ablation, defined by stimulated thyroglobulin, whole body scan and ultrasound imaging. (3) Results-an excellent response rate of 79.8% in the low-dose group and 85.7% in the high-dose group was observed (p = 0.049). Stimulated thyroglobulin at the moment of ablation (p = 0.032) and positive antithyroglobulin antibodies (p < 0.001) were independent predictive factors for nonexcellent response. Young age (p = 0.023), intermediate initial recurrence risk (p < 0.001) and low-dose ablation (p = 0.004) were independent predictive factors for recurrence. (4) Conclusion-low-dose ablation seemed to be less effective than high-dose ablation, especially in those patients with positive antithyroglobulin antibodies or higher stimulated thyroglobulin levels at the moment of ablation. Low dose was associated with higher recurrence rates, and lower age and intermediate initial recurrence risk were independent risk factors for recurrence in our sample.

New molecular biomarkers in differentiated thyroid carcinoma: Impact of miR-146, miR-221 and miR-222 levels in the evolution of the disease.

OBJECTIVE: MircroRNAs (miR) are small, noncoding RNA molecules of 18-25 nucleotides. Their dysregulation has been widely studied in many human tumours including differentiated thyroid cancer (DTC). miRs more frequently associated with these kinds of tumours are miR-146, miR-221 and miR-222. Our objective was to assess the relationship among circulating miR levels and the evolution and outcomes of disease. DESIGN: We analysed a sample of 60 patients with DTC assigning them to one of three groups according to the dynamic scale of risk (excellent response, incomplete biochemical response and incomplete structural response). PATIENTS AND MEASUREMENTS: At study inclusion, we determined thyroid-stimulating hormone, thyroxine, thyroglobulin, antithyroglobulin antibodies and plasma levels of miR-146, miR-221 and miR-222. RESULTS: Male sex and advanced age at diagnosis were associated with the worst disease progression. miR-222 was twofold to threefold higher in tall cell papillary carcinomas (P = 0.038). miR-146 (P = 0.016) and miR-221 (P = 0.050) had a positive correlation with thyroglobulin at the time of sampling. In regression analysis, miR-146 (P = 0.006), miR-221 (P = 0.004) and miR-222 (P = 0.007) predicted more than 70% of the variation in thyroglobulin levels at the time of sampling. CONCLUSIONS: Elevated miR-222 and miR-146 levels are associated with poorer outcomes of the disease and may have a prognostic value in the management and follow-up of DTC.

Evaluation of a New Digital Automated Glycemic Pattern Detection Tool.

BACKGROUND: Blood glucose meters are reliable devices for data collection, providing electronic logs of historical data easier to interpret than handwritten logbooks. Automated tools to analyze these data are necessary to facilitate glucose pattern detection and support treatment adjustment. These tools emerge in a broad variety in a more or less nonevaluated manner. The aim of this study was to compare eDetecta, a new automated pattern detection tool, to nonautomated pattern analysis in terms of time investment, data interpretation, and clinical utility, with the overarching goal to identify early in development and implementation of tool areas of improvement and potential safety risks. METHODS: Multicenter web-based evaluation in which 37 endocrinologists were asked to assess glycemic patterns of 4 real reports (2 continuous subcutaneous insulin infusion [CSII] and 2 multiple daily injection [MDI]). Endocrinologist and eDetecta analyses were compared on time spent to analyze each report and agreement on the presence or absence of defined patterns. RESULTS: eDetecta module markedly reduced the time taken to analyze each case on the basis of the emminens eConecta reports (CSII: 18 min; MDI: 12.5), compared to the automatic eDetecta analysis. Agreement between endocrinologists and eDetecta varied depending on the patterns, with high level of agreement in patterns of glycemic variability. Further analysis of low level of agreement led to identifying areas where algorithms used could be improved to optimize trend pattern identification. CONCLUSION: eDetecta was a useful tool for glycemic pattern detection, helping clinicians to reduce time required to review emminens eConecta glycemic reports. No safety risks were identified during the study.

Changes in the incidence of pneumonia, bacterial meningitis, and infant mortality 5 years following introduction of the 13-valent pneumococcal conjugate vaccine in a "3+0" schedule.

BACKGROUND: Streptococcus pneumoniae causes about 826,000 deaths of children in the world each year and many health facility visits. To reduce the burden of pneumococcal disease, many nations have added pneumococcal conjugate vaccines to their national immunization schedules. Nicaragua was the first country eligible for GAVI Alliance funding to introduce the 13-valent pneumococcal conjugate vaccine (PCV13) in 2010, provided to infants at 2, 4, and 6 months of age. The goal of this study was to evaluate the population impact of the first five years of the program. METHODS: Numbers of visits for pneumonia, pneumonia-related deaths, and bacterial meningitis in both children and adults, and infant deaths between 2008 and 2015 were collected from all 107 public health facilities in León Department. Vital statistics data provided additional counts of pneumonia-related deaths that occurred outside health facilities. Adjusted incidence rates and incidence rate ratios (IRRa) in the vaccine (2011-2015) and pre-vaccine periods (2008-2010) were estimated retrospectively using official population estimates as exposure time. RESULTS: The IRRa for pneumonia hospitalizations was 0.70 (95% confidence interval [CI]: 0.66, 0.75) for infants, and 0.92 (95% CI: 0.85, 0.99) for one year-olds. The IRRa for post-neonatal infant mortality was 0.56 (95% CI: 0.41, 0.77). In the population as a whole, ambulatory visits and hospitalizations for pneumonia, as well as pneumonia-related mortality and rates of bacterial meningitis were lower in the vaccine period. CONCLUSIONS: During the first five years of program implementation, reductions were observed in health facility visits for pneumonia in immunized age groups and infant mortality, which would be hard to achieve with any other single public health intervention. Future study is warranted to understand whether the lack of a booster dose (e.g., at 12 months) may be responsible for the small reductions in pneumonia hospitalizations observed in one year-olds as compared to infants.

Impact of a combined pediatric and adult pneumococcal immunization program on adult pneumonia incidence and mortality in Nicaragua.

BACKGROUND: In 2010, Nicaragua implemented an adult immunization program with the 23-valent pneumococcal polysaccharide vaccine (PPSV-23) and a pediatric immunization program with the 13-valent pneumococcal conjugate vaccine (PCV-13). We assessed incidence rates of ambulatory visits and hospitalizations for pneumonia and pneumonia-related mortality in adults over the age of 50 years before and after the program's implementation in the Department of León, Nicaragua. METHODS: We collected visit diagnoses from all 107 public health facilities between 2008 and 2012 in León. We compared incidence rates of ambulatory visits for pneumonia, pneumonia hospitalizations, and pneumonia-related mortality in the pre-vaccine (2008-2009) and vaccine (2011-2012) periods among older adults using Poisson regression with generalized estimating equations (GEE), controlling for age group, municipality, and proportions of adults who were immunized against influenza. Exposure time was estimated by official municipality population estimates. RESULTS: We did not observe lower incidence rates of ambulatory visits or hospitalizations for pneumonia among adults during the vaccine period versus the pre-vaccine period. However, pneumonia-related mortality was lower in the vaccine period versus the pre-vaccine period, with an adjusted incidence rate ratio (IRRa) of 0.73 (0.56, 0.94) among adults aged 50-64 years, and 0.55 (0.43, 0.70) among adults aged ≥65 years. CONCLUSIONS: These early results following introduction of a combined pediatric and adult pneumococcal immunization program in Nicaragua show a probable impact of the program on the reduction of pneumonia-related deaths in older adults, but a less clear impact on the reduction of health facility visits for pneumonia.

Changes in childhood pneumonia and infant mortality rates following introduction of the 13-valent pneumococcal conjugate vaccine in Nicaragua.

BACKGROUND: In 2010, Nicaragua became the first developing nation to add 13-valent pneumococcal conjugate vaccine (PCV-13) to its national immunization schedule, using a "3+0" dosing schedule. We assessed changes in incidence rates of health facility visits for childhood pneumonia and infant mortality after PCV-13 introduction in the Department of León, Nicaragua. METHODS: We collected visit diagnoses from all 107 public health facilities in León between 2008 and 2012. We compared rates of pneumonia hospitalizations, ambulatory visits for pneumonia and infant mortality during the prevaccine (2008-2010) and vaccine (2011-2012) periods among different age groups of children using generalized estimating equations, accounting for clustering by municipality. Exposure time was estimated by official municipality population estimates. RESULTS: The adjusted incidence rate ratio for pneumonia hospitalization in the vaccine versus prevaccine period was 0.67 (0.59-0.75) among infants and 0.74 (0.67-0.81) among 1-year olds. The adjusted incidence rate ratio for ambulatory visits for pneumonia was 0.87 (0.75-1.01) among infants, and 0.84 (0.74, 0.95) among 1-year olds. The adjusted incidence rate ratio for infant mortality was 0.67 (0.57-0.80). We also observed lower rates of health facility visits for pneumonia among age groups (2- to 4-year old and 5- to 14-year old) not eligible to receive PCV-13. CONCLUSIONS: Within the first 2 years of a PCV-13 immunization program in Nicaragua, we observed lower rates of hospitalizations and ambulatory visits for pneumonia among children of all ages and a lower infant mortality rate. Lower rates of pneumonia among age groups not eligible to receive PCV-13 suggest an indirect effect of the vaccine.

Metabolic effects of an enteral nutrition formula for diabetes: comparison with standard formulas in patients with type 1 diabetes.

AIM: To evaluate the metabolic response (glucose, cholesterol, triglycerides and beta-hydroxy-butyrate) in patients with type 1 diabetes after a trial breakfast with an enteral nutrition formula designed for patients with diabetes and compare it with standard formulas (with and without fibre). MATERIAL AND METHODS: Each of 11 patients with type 1 diabetes consumed three types of liquid breakfast with a 1 week interval between each. (1). A standard diet (SD) with 49% carbohydrates, 35% lipids, 16% proteins-casein-and without fibre; (2). A fibre-enriched diet (FD): with 49% carbohydrates, 35% lipids, 16% casein and 15 g/1000 ml fibre; (3). A diet designed for patients with diabetes (DD) with 45% carbohydrates, 38% lipids, 16% soy protein and 15 g/1000 ml fibre. Each subject consumed 250 ml of each preparation at 9.00 AM after having administered their usual insulin dose, which was the same for each diet. Blood samples were taken at baseline and each 30 min, up to 150 min. RESULTS: The increase in postprandial glycaemia was lower with DD than with the standard preparations, reaching statistical significance at 60 min. There were no significant variations in the levels of cholesterol, triglycerides or beta-hydroxy-butyrate between the three preparations. CONCLUSIONS: After a trial breakfast, a diet designed for patients with diabetes provoked lower increases in postprandial glycaemia (with no changes in lipid or beta-hydroxy-butyrate levels) compared to the standard diets evaluated (with and without fibre).
