RESUMO

OBJECTIVES: To describe the demographic characteristics and clinical outcomes following the first cohort of patients with Bening Thyroid Nodule (BTN) and (Papillary Thyroid Microcarcinoma) (PTMC) treated with Radiofrequency Ablation (RFA)in Ecuador. METHODS: Single-center, cross-sectional study. We included adults undergoing RFA for BTN and PTMC between July 2019 and May 2022. Descriptive statistics and the Wilcoxon signed-rank test were used to compare some pre- and post-intervention outcomes. RESULTS: We included 44 patients with 36 BTNs and eight PTMCs. The median age was 45.80 years (IQR 16-79 years), and most patients had normal thyroid function (72.72%). The median follow-up time was 7.80 months (IQR1.0-34.0). Nodules were primarily solid (43.21%) or predominantly solid (56.81%). The pre-RFA median volume in the benign lesions group was 10.30 ml (IQR 1.86-18.97). After ablation, the 1-month, 3-month, 6-month, and 12-month median volumes were 6.90 (IQR 0.48-10.15; p < 0.01) mL, 5.72 (IQR 0.77-7.25; p = 0.045); 0.98 (IQR 0.25-3.64; p < 0.01), and 0.11 (IQR 0.07-11.26; p = 0.026), respectively. The volume rate reduction was 47.20%, 72.20%, 74.00%, and 96.20% at 1, 3, 6, and 12-month follow-ups, respectively. The pre-RFA median volume in the PTMC group was 0.25 ml (IQR 0.19-0.48). After ablation, the 1-month, 3-month, and 6-month mean volumes were 0.19 (range 0.12-0.31; p = 0.120) mL, 0.10 (IQR 0.05-0.15; p = 0.13), and 0.01 (IQR 0.005-0.04; p = 0.364), respectively. CONCLUSIONS: In this first report from Ecuador, we found that RFA may be a feasible alternative for treating benign and malignant thyroid nodules in the short term. Long-term data are needed to evaluate oncologic outcomes in PTMC patients.

RESUMO

BACKGROUND: The global prevalence of thyroid cancer is on the rise. About one-third of newly diagnosed thyroid cancer cases comprise low-risk papillary thyroid cancer (1.5 cm or more minor). While surgical removal remains the prevailing approach for managing low-risk papillary thyroid cancer (LPTC) in patients, other options such as active surveillance (AS), radiofrequency ablation (RFA), microwave ablation (MWA), and laser ablation (LA) are also being considered as viable alternatives. This study evaluated and compared surgical thyroid resection (TSR) versus non-surgical (NS) methods for treating patients with LPTC. METHODS: The study encompassed an analysis of comparisons between surgical thyroid resection (TSR) and alternative approaches, including active surveillance (AS), radiofrequency ablation (RFA), microwave ablation (MWA), or laser ablation (LA). The focus was on patients with biopsy-confirmed low-risk papillary thyroid cancer (LPTC) of less than 1.5 cm without preoperative indications of local or distant metastasis. The primary outcomes assessed were recurrence rates, disease-specific mortality, and quality of life (QoL). Data were collected from prominent databases, including Cochrane Database, Embase, MEDLINE, and Scopus, from inception to June 3rd, 2020. The CLARITY tool was utilized to evaluate bias risk. The analysis involved odds ratios (OR) with 95% confidence intervals (CI) for dichotomous outcomes, as well as mean differences (MD) and standardized mean differences (SMD) for continuous outcomes. The study is registered on PROSPERO under the identifier CRD42021235657. RESULTS: The study incorporated 13 retrospective cohort studies involving 4034 patients. Surgical thyroid resection (TSR), active surveillance (AS), and minimally invasive techniques like radiofrequency ablation (RFA), microwave ablation (MWA), and laser ablation (LA) were performed in varying proportions of cases. The analysis indicated that specific disease mortality rates were comparable among AS, MWA, and TSR groups. The risk of recurrence, evaluated over different follow-up periods, showed no significant differences when comparing AS, RFA, MWA, or LA against TSR. Patients undergoing AS demonstrated better physical health-related quality of life (QoL) than those undergoing TSR. However, no substantial differences were observed in the overall mental health domain of QoL when comparing AS or RFA with TSR. The risk of bias was moderate in nine studies and high in four. CONCLUSION: Low-quality evidence indicates comparable recurrence and disease-specific mortality risks among patients with LPTC who underwent ablation techniques or active surveillance (AS) compared to surgery. Nevertheless, individuals who opted for AS exhibited enhanced physical quality of life (QoL). Subsequent investigations are warranted to validate these findings.

RESUMO

CONTEXT: Thyroid nodule risk stratification allows clinicians to standardize the evaluation of thyroid cancer risk according to ultrasound features. OBJECTIVE: To evaluate interrater agreement among clinicians assessing thyroid nodules ultrasound features and thyroid cancer risk categories. DESIGN, SETTING, AND PARTICIPANTS: We surveyed Endocrine Society and Latin American Thyroid Society members to assess their interpretation of composition, echogenicity, shape, margins, and presence of echogenic foci of 10 thyroid nodule cases. The risk category for thyroid cancer was calculated following the American College of Radiology-Thyroid Imaging Reporting & Data System (ACR-TIRADS) framework from individual responses. MAIN OUTCOMES AND MEASURES: We used descriptive statistics and Gwet's agreement coefficient (AC1) to assess the primary outcome of interrater agreement for ACR-TIRADS risk category. As secondary outcomes, the interrater agreement for individual features and a subgroup analysis of interrater agreement for the ACR-TIRADS category were performed (ultrasound reporting system, type of practice, and number of monthly appraisals). RESULTS: A total of 144 participants were included, mostly endocrinologists. There was moderate level of agreement for the absence of echogenic foci (AC1 0.53, 95% CI 0.24-0.81) and composition (AC1 0.54, 95% CI 0.36-0.71). The agreement for margins (AC1 0.24, 95% CI 0.15-0.33), echogenicity (AC1 0.34, 95% CI 0.22-0.46), and shape assessment (AC1 0.42, 95% CI 0.13-0.70) was lower. The overall agreement for ACR-TIRADS assessment was AC1 0.29, (95% CI 0.13-0.45). The AC1 of ACR-TIRADS among subgroups was similar. CONCLUSIONS: This study found high variation of judgments about ACR-TIRADS risk category and individual features, which poses a potential challenge for the widescale implementation of thyroid nodule risk stratification.

RESUMO

AIMS: Address treatment burden and general perceptions of pharmacological treatment in patients with diabetes. METHODS: We surveyed adult patients with diabetes cared for in a tertiary academic medical center about: i) knowledge about the impact of glucose-lowering medication use on diabetes control and complications, ii) common beliefs about natural medicine and insulin use, iii) attitudes towards glucose-lowering medications, iv) burden of treatment, v) general knowledge of diabetes pharmacological treatment, and vi) perceptions of shared decision-making. RESULTS: Two hundred-four participants completed the survey. While most (90%) agreed that adherence to medication would control diabetes and improve quality of life, 30-40% were not certain that it would translate to fewer disease complications. About one of three thought medications could be harmful (29.4%). Over 50% agreed or was unsure that natural remedies were as good/better than prescribed medications. About 30% acknowledged difficulties taking their diabetes medications and monitoring blood glucose, and over 50% were concerned about treatment costs. Nearly 30% denied receiving a detailed explanation from their clinician regarding their disease and is treatment. CONCLUSIONS: Our results highlight the importance of patient education regarding pharmacological treatment for diabetes, and eliciting sources of distress and treatment burden among patients with diabetes.

RESUMO

AIMS: Examine the efficacy of metformin compared to placebo or other glucose-lowering medications on microvascular outcomes in patients with Type 2 Diabetes Mellitus (T2DM). METHODS: MEDLINE, EMBASE, Web of Science, and Scopus were searched from database inception to March 2020. We included randomized clinical trials of patients with T2DM receiving metformin compared with another active glucose-lowering treatment or placebo in which a microvascular outcome was assessed. The risk of bias was assessed using the Cochrane Risk of Bias tool. Microvascular complications included kidney-related outcomes, retinopathy, and peripheral neuropathy. An inverse-weighted variance random-effect meta-analysis was performed to estimate drugs effect over microvascular disease. PROSPERO (CRD42019120365). RESULTS: Nineteen RCTs (n = 18,181) were included. Metformin increased estimated glomerular filtration rate (eGFR) by a mean difference (MD) of 1.08 (95% CI 0.84 to 1.33 ml/min/1.73 m2) after 24 weeks. No effect was found on urinary albumin-creatinine ratio, serum creatinine, and end-stage kidney disease; Patient-important outcomes regarding kidney disease, retinal outcomes, peripheral neuropathy or quality of life were not assessed by any of the included studies and could not be analyzed. CONCLUSIONS: There is no evidence of clinically significant beneficial effect of metformin therapy as compared to other glucose-lowering medications or placebo on the examined microvascular complications.

RESUMO

BACKGROUND: In contrast to the rapid increase in thyroid cancer incidence, the mortality has remained low and stable over the last decades. In Ecuador, however, thyroid cancer mortality has increased. The objective of this study is to determine possible drivers of high rates of thyroid cancer mortality, through a cross-sectional analysis of all patients attending a thyroid cancer referral center in Ecuador. METHODS: From June 2014 to December 2017, a cross-sectional study was conducted at the Hospital de Especialidades Eugenio Espejo, a regional reference public hospital for endocrine neoplasia in adults in Quito, Ecuador. We identified the mechanism of detection, histopathology and treatment modalities from a patient interview and review of clinical records. RESULTS: Among 452 patients, 74.8% were young adults and 94.2% (426) were female. 13.7% had a family history of thyroid cancer, and patients' median tumor size was 2 cm. The incidental finding was 54.2% whereas 45.8% was non-incidental. Thyroid cancer histology reported that 93.3% had papillary thyroid cancer (PTC), 2.7% follicular, 1.5% Hurtle cells, 1.6% medullary, 0.7% poor differentiated, and 0.2% anaplastic carcinoma. The mean MACIS (metastasis, age, completeness, invasion, and size) score was 4.95 (CI 4.15-5.95) with 76.2% of the thyroid cancer patients having MACIS score less than or equal to 6. The very low and low risk of recurrence was 18.1% (79) and 62% (271) respectively. An analysis of 319 patients with non-metastatic thyroid cancer showed that 10.7% (34) of patients had surgical complications. Moreover, around 62.5% (80 from 128 patients with thyroglobulin laboratory results) of TC patients had a stimulated-thyroglobulin value equal or higher than 2 ng/ml. Overall, a poor surgical outcome was present in 35.1% (112) patients. Out of 436 patients with differentiated thyroid carcinoma, 86% (375) received radioactive iodine. CONCLUSION: Thyroid cancer histological characteristics and method of diagnosis are like those described in other reports without any evidence of the high frequency of aggressive thyroid cancer histology. However, we observed evidence of overtreatment and poor surgical outcomes that demand additional studies to understand their association with thyroid cancer mortality in Ecuador.

RESUMO

PURPOSE: Clinical guidelines include recommendations to guide patient's longitudinal care. These recommendations may differ in content and quality of supporting evidence from those guiding diagnosis and treatment. We aimed to identify recommendations guiding the follow-up of patients with endocrine conditions, describe their content and quality of evidence. METHODS: We systematically assessed the Endocrine Society and the American Thyroid Association clinical guidelines and identified recommendations guiding follow-up strategies to evaluate direction, content, strength, and quality of evidence. RESULTS: Out of 1540 recommendations, 138(8.9%) guided follow-up strategies. From these, 109 (79%) recommendations included goal of follow-up, 121(97.7%) suggested follow-up methods, and 56 (40.6%) a specific monitoring frequency. A total of 76 (55.1%) assessed treatment response, 65 (47.1%) disease progression, and 30 (21.7%) side effects. A total of 90 (65.2%) described the use of laboratory studies, 30 (21.7%) clinical exam/history, and 27 (19.6%) imaging studies. Finally, 91 (65.9%) suggested a monitoring time interval and 42 (30.4%) directed an action based on results. Most recommendations [88 (55.3%)] were based on low/very low-quality evidence. A total of 73 (52.9%) recommendations were labeled as strong, from which 12% were based on high-quality evidence. CONCLUSIONS: One out of ten clinical recommendations for endocrine conditions guide follow-up and their content is variable. More than half of the follow-up recommendations are supported by low/very low-quality evidence and the majority does not provide an action threshold. A specific framework for developing follow-up recommendations can aid guideline panelists and support evidence-based monitoring.

RESUMO

Background: Levothyroxine (LT4) is one of the most commonly prescribed medications. Although considered a life-long replacement therapy, LT4 therapy can be discontinued for some patients. This study aims at: (i) reviewing the evidence on clinical outcomes of patients undergoing thyroid hormone replacement discontinuation, (ii) identifying the predictors of successful discontinuation, and (iii) systematically appraising frameworks used for deprescribing thyroid hormone. Methods: We searched multiple bibliographic databases, including Ovid MEDLINE(R) and Epub Ahead of Print, In-Process & Other Non-Indexed Citations and Daily, Ovid Embase, Ovid Cochrane Central Register of Controlled Trials, Ovid Cochrane Database of Systematic Reviews, and Scopus, from inception to February 2020 for studies in which thyroid hormone replacement was discontinued. Clinical outcomes assessed included: proportion of patients that remained euthyroid or needed to restart thyroid hormone replacement after discontinuation and frequency of clinical symptoms of hypothyroidism and adverse effects. We also evaluated predictors for discontinuation and deprescribing frameworks. Reviewers (F.J.K.T., N.B., N.M.S.O., S.M.) evaluated studies for inclusion, extracted data, and assessed methodological quality independently and in duplicate. Results: Seventeen observational studies at moderate to high risk of bias met inclusion criteria, including a total of 1103 patients (86% women) with an age range of 2-81 years. Approximately a third of patients undergoing thyroid hormone discontinuation remained euthyroid at follow-up (37.2%, 95% confidence interval [CI 24.2-50.1%], I2 97.5%). Subgroup analysis showed that patients with a previous diagnosis of overt hypothyroidism (OH) were less likely to remain euthyroid (11.8% [CI 0.4-23.2%], I2 90.3%) than patients with a prior diagnosis of subclinical hypothyroidism (SCH) (35.6% [CI 8.2-62.9%], I2 94.0%). No study followed a framework for systematically deprescribing LT4. Conclusions: Low-quality evidence suggests that up to a third of patients remained euthyroid after thyroid hormone discontinuation, with a higher proportion of patients with an initial diagnosis of SCH remaining euthyroid than patients with an initial diagnosis of OH. A deprescribing framework focusing on adequate selection of patients for deprescribing LT4 and a systematic process is warranted to guide clinicians in re-evaluating the need for LT4 in their patients.

RESUMO

Coronavirus disease 2019 (Covid-19) has affected millions of people and may disproportionately affect those with hypertension and diabetes. Because of inadequate methods in published systematic reviews, the prevalence of diabetes and hypertension and associated risks of poor outcomes in Covid-19 patients are unknown. We searched databases from December 1, 2019, to April 6, 2020, and selected observational peer-reviewed studies in English of patients with Covid-19. Independent reviewers extracted data on study participants, interventions, and outcomes and assessed risk of bias, and the certainty of evidence. We included 65 (15 794 participants) observational studies at moderate to high risk of bias. Overall prevalence of diabetes and hypertension was 12% (95% confidence interval [CI], 10-15; n = 12 870; I 2: 89%), and 17% (95% CI, 13-22; n = 12 709; I 2: 95%), respectively. In severe Covid-19, the prevalence of diabetes and hypertension were 18% (95% CI, 16-20; n = 1099; I 2: 0%) and 32% (95% CI, 16-54; n = 1078; I 2: 63%), respectively. Unadjusted relative risk for intensive care unit admission and mortality were 1.96 (95% CI, 1.19-3.22; n = 8890; I 2: 80%; P = .008) and 2.78 (95% CI, 1.39-5.58; n = 2058; I 2: 75%; P = .0004) for diabetics; and 2.95 (95% CI, 2.18-3.99; n = 1737; I 2: 0%; P < .001) and 2.39 (95% CI, 1.54-3.73; n = 3107; I 2: 66%; P < .001) for hypertensives. Neither diabetes (1.50; 95% CI, 0.90-2.50; n = 1991; I 2: 74%; P = .119) nor hypertension (1.48; 95% CI, 0.99-2.23; n = 2023; I 2: 69%; P = .058) was associated with severe Covid-19. In conclusion, the risk of intensive care unit admission and mortality for patients with diabetes or hypertension who developed Covid-19 is increased compared with those without these comorbidities.

RESUMO

OBJECTIVES: To improve the trustworthiness of evidence, studies should be prospectively registered and research reports should adhere to existing standards. We aimed to systematically assess the degree to which endocrinology and internal medicine journals endorse study registration and reporting standards for randomised controlled trials (RCTs), systematic reviews (SRs) and observational studies (ObS). Additionally, we evaluated characteristics that predict endorsement of reporting or registration mechanism by these journals. DESIGN: Meta-epidemiological study. SETTING: Journals included in the 'Endocrinology and Metabolism' and 'General and Internal Medicine' 2017 Journal Citation Reports. PARTICIPANTS: Journals with an impact factor of ≥1.0, focused on clinical medicine, and those who publish RCTs, SRs and ObS were included. PRIMARY OUTCOMES: Requirement of adherence to reporting guideline and study registration as determined from the journals' author instructions. RESULTS: Of the 170 (82 endocrinology and 88 internal medicine) eligible journals, endorsing of reporting standards was the highest for RCTs, with 35 (43%) of endocrine journals and 55 (63%) of internal medicine journals followed by SRs, with 21 (26%) and 48 (55%), respectively, and lastly, by ObS with 41 (50%) of endocrine journals and 21 (24%) of internal medicine journals. In 78 (46%) journals RCTs were required to be registered and published in adherence to the Consolidated Standards of Reporting Trials statement. Only 11 (6%) journals required registration of SRs. Internal medicine journals were more likely to endorse reporting guidelines than endocrine journals except for Strengthening the Reporting of Observational Studies in Epidemiology. No other journal characteristic proved to be an independent predictor of reporting standard endorsement for RCTs besides trial registration. CONCLUSION: Our results highlight that study registration requirement and reporting guideline endorsement are suboptimal in internal medicine and endocrine journals. This malpractice may be further enhanced since endorsement does not imply enforcement, impairing the practice of evidence-based medicine.

RESUMO

BACKGROUND: Thyroid cancer is the most frequent endocrine neoplasia worldwide. Information from Andean countries is scarce. In Ecuador there is no reports available of the epidemiology of this type of cancer. The aim of this study is to present the epidemiology and the burden of disease of thyroid cancer. METHODS: This is a cross-sectional population-based analysis of thyroid cancer epidemiology in Ecuador from 2001 to 2016. The variables studied were the overall mortality rate, socio-demographics characteristics of the hospitalized patients, geographical trends and the burden of thyroid cancer in Ecuador. All the data was obtained from the official records reported by the Ministry of Public Health's and retrieved from the public databases of the Vital Statistics Deaths and Births Databases and the National Institute of Census and Statistics (INEC). RESULTS: In Ecuador, over a period of 16 years from 2001 to 2016 a total of 23,632 hospital admissions were reported, which caused 1539 deaths due thyroid cancer. Data demonstrated an annual mean of 1477 cases, which caused 96 deaths per year in average. The annual incidence fluctuated from 3 in 2001 to 22 in 2016 per 100,000 inhabitants. Women were 5 times more likely than men to have thyroid cancer. The average length of stay for both sexes were 4 days. The mortality attributable to thyroid cancer represent less than 0.3% of all cancer deaths. CONCLUSION: Ecuador has one of the highest rates of thyroid cancer in Latin America, ranking first among women in Latin America. Although this cancer is frequent, mortality rate is relatively low. As this is the first national report of thyroid cancer in the country, a further analysis of the pathological variants and the grading of this neoplasia is needed.

RESUMO

The incidence of thyroid cancer has increased, mainly due to the incidental finding of low-risk papillary thyroid cancers (PTC). These malignancies grow slowly, and are unlikely to cause morbidity and mortality. New understanding about the prognosis of tumor features has led to reclassification of many tumors within the low-risk thyroid category, and to the development of a new one "very low-risk tumors." Alternative less aggressive approaches to therapy are now available including active surveillance and minimally invasive interventions. In this narrative review, we have summarized the available evidence for the management of low-risk PTC.

RESUMO

In medicine and endocrinology, there are few clinical circumstances in which clinicians can accurately predict what is best for their patients. As a result, patients and clinicians frequently have to make decisions about which there is uncertainty. Uncertainty results from limitations in the research evidence, unclear patient preferences, or an inability to predict how treatments will fit into patients' daily lives. The work that patients and clinicians do together to address the patient's situation and engage in a deliberative dialogue about reasonable treatment options is often called shared decision making. Decision aids are evidence-based tools that facilitate this process. Shared decision making is a patient-centred approach in which clinicians share information about the benefits, harms, and burden of different reasonable diagnostic and treatment options, and patients explain what matters to them in view of their particular values, preferences, and personal context. Beyond the ethical argument in support of this approach, decision aids have been shown to improve patients' knowledge about the available options, accuracy of risk estimates, and decisional comfort. Decision aids also promote patient participation in the decision-making process. Despite accumulating evidence from clinical trials, policy support, and expert recommendations in endocrinology practice guidelines, shared decision making is still not routinely implemented in endocrine practice. Additional work is needed to enrich the number of available tools and to implement them in practice workflows. Also, although the evidence from randomised controlled trials favours the use of this shared decision making in other settings, populations, and illnesses, the effect of this approach has been studied in a few endocrine disorders. Future pragmatic trials are needed to explore the effect and feasibility of shared decision making implementation into routine endocrinology and primary care practice. With the available evidence, however, endocrinologists can now start to practice shared decision making, partner with their patients, and use their expertise to formulate treatment plans that reflect patient preferences and are more likely to fit into the context of patients' lives. In this Personal View, we describe shared decision making, the evidence behind the approach, and why and how both endocrinologists and their patients could benefit from this approach.

RESUMO

Chronic diseases are the leading cause of morbidity and mortality worldwide. These conditions require considerable time investment and resources from the health system in Peru, as well as from patients and their families. Paradoxically, the developed medical strategies for managing these conditions generate a constant and increasing burden for the patient and their environment, which affects quality of life and therapeutic results. In this article, the role of shared decision making and minimal disruptive medicine will be described as strategies to address these problems.

RESUMO

Hashimoto's thyroiditis is the most frequent cause of hypothyroidism. In the regions with no iodine deficiency, it is more frequent in women and oftentimes has a familial association. The symptoms and signs of hypothyroidism are systemic and depend on the duration and intensity of the thyroid hormone deficiency. Neuromuscular manifestations are seldom the only symptoms and signs present. We present the case of a young patient with severe myopathy, where rhabdomyolysis was the sole manifestation of severe hypothyroidism secondary to Hashimoto's thyroiditis.

RESUMO

La tiroiditis de Hashimoto constituye la causa más frecuente de hipotiroidismo en las regiones sin deficiencia de yodo, es más frecuente en mujeres y muchas veces tiene asociación familiar. Los síntomas y signos del hipotiroidismo son sistémicos y dependen de la duración e intensidad de la deficiencia de la hormona tiroidea. Las manifestaciones neuromusculares, son excepcionalmente los únicos signos clínicos. Se presenta el caso de un paciente joven con una miopatía severa con rabdomiolisis como la única manifestación de hipotiroidismo severo debido a tiroiditis de Hashimoto.


Hashimoto’s thyroiditis is the most frequent cause of hypothyroidism. In the regions with no iodine deficiency, it is more frequent in women and oftentimes has a familial association. The symptoms and signs of hypothyroidism are systemic and depend on the duration and intensity of the thyroid hormone deficiency. Neuromuscular manifestations are seldom the only symptoms and signs present. We present the case of a young patient with severe myopathy, where rhabdomyolysis was the sole manifestation of severe hypothyroidism secondary to Hashimoto’s thyroiditis.
