American Association of Clinical Endocrinology Clinical Practice Guideline for the Diagnosis and Management of Nonalcoholic Fatty Liver Disease in Primary Care and Endocrinology Clinical Settings: Co-Sponsored by the American Association for the Study of Liver Diseases (AASLD)

ObjectiveTo provide evidence-based recommendations regarding the diagnosis and management of nonalcoholic fatty liver disease (NAFLD) and nonalcoholic steatohepatitis (NASH) to endocrinologists, primary care clinicians, health care professionals, and other stakeholders.MethodsThe American Association of Clinical Endocrinology conducted literature searches for relevant articles published from January 1, 2010, to November 15, 2021. A task force of medical experts developed evidence-based guideline recommendations based on a review of clinical evidence, expertise, and informal consensus, according to established American Association of Clinical Endocrinology protocol for guideline development.Recommendation SummaryThis guideline includes 34 evidence-based clinical practice recommendations for the diagnosis and management of persons with NAFLD and/or NASH and contains 385 citations that inform the evidence base.ConclusionNAFLD is a major public health problem that will only worsen in the future, as it is closely linked to the epidemics of obesity and type 2 diabetes mellitus. Given this link, endocrinologists and primary care physicians are in an ideal position to identify persons at risk on to prevent the development of cirrhosis and comorbidities. While no U.S. Food and Drug Administration-approved medications to treat NAFLD are currently available, management can include lifestyle changes that promote an energy deficit leading to weight loss; consideration of weight loss medications, particularly glucagon-like peptide-1 receptor agonists; and bariatric surgery, for persons who have obesity, as well as some diabetes medications, such as pioglitazone and glucagon-like peptide-1 receptor agonists, for those with type 2 diabetes mellitus and NASH. Management should also promote cardiometabolic health and reduce the increased cardiovascular risk associated with this complex disease.     

American Association of Clinical Endocrinology Consensus Statement: Comprehensive Type 2 Diabetes Management Algorithm – 2023 Update

ObjectiveThis consensus statement provides (1) visual guidance in concise graphic algorithms to assist with clinical decision-making of health care professionals in the management of persons with type 2 diabetes mellitus to improve patient care and (2) a summary of details to support the visual guidance found in each algorithm.MethodsThe American Association of Clinical Endocrinology (AACE) selected a task force of medical experts who updated the 2020 AACE Comprehensive Type 2 Diabetes Management Algorithm based on the 2022 AACE Clinical Practice Guideline: Developing a Diabetes Mellitus Comprehensive Care Plan and consensus of task force authors.ResultsThis algorithm for management of persons with type 2 diabetes includes 11 distinct sections: (1) Principles for the Management of Type 2 Diabetes; (2) Complications-Centric Model for the Care of Persons with Overweight/Obesity; (3) Prediabetes Algorithm; (4) Atherosclerotic Cardiovascular Disease Risk Reduction Algorithm: Dyslipidemia; (5) Atherosclerotic Cardiovascular Disease Risk Reduction Algorithm: Hypertension; (6) Complications-Centric Algorithm for Glycemic Control; (7) Glucose-Centric Algorithm for Glycemic Control; (8) Algorithm for Adding/Intensifying Insulin; (9) Profiles of Antihyperglycemic Medications; (10) Profiles of Weight-Loss Medications (new); and (11) Vaccine Recommendations for Persons with Diabetes Mellitus (new), which summarizes recommendations from the Advisory Committee on Immunization Practices of the U.S. Centers for Disease Control and Prevention.ConclusionsAligning with the 2022 AACE diabetes guideline update, this 2023 diabetes algorithm update emphasizes lifestyle modification and treatment of overweight/obesity as key pillars in the management of prediabetes and diabetes mellitus and highlights the importance of appropriate management of atherosclerotic risk factors of dyslipidemia and hypertension. One notable new theme is an emphasis on a complication-centric approach, beyond glucose levels, to frame decisions regarding first-line pharmacologic choices for the treatment of persons with diabetes. The algorithm also includes access/cost of medications as factors related to health equity to consider in clinical decision-making.     

Transcultural Diabetes Care in The United States – A Position Statement by the American Association of Clinical Endocrinologists

The American Association of Clinical Endocrinologists (AACE) has created a transculturalized diabetes chronic disease care model that is adapted for patients across a spectrum of ethnicities and cultures. AACE has conducted several transcultural activities on global issues in clinical endocrinology and completed a 3-city series of conferences in December 2017 that focused on diabetes care for ethnic minorities in the U.S. Proceedings from the “Diabetes Care Across America” series of transcultural summits are presented here. Information from community leaders, practicing health care professionals, and other stakeholders in diabetes care is analyzed according to biological and environmental factors. Four specific U.S. ethnicities are detailed: African Americans, Latino/Hispanics, Asian Americans, and Native Americans. A core set of recommendations to culturally adapt diabetes care is presented that emphasizes culturally appropriate terminology, transculturalization of white papers, culturally adapting clinic infrastructure, flexible office hours, behavioral medicine—especially motivational interviewing and building trust—culturally competent nutritional messaging and health literacy, community partnerships for care delivery, technology innovation, clinical trial recruitment and retention of ethnic minorities, and more funding for scientific studies on epigenetic mechanisms of cultural impact on disease expression. It is hoped that through education, research, and clinical practice enhancements, diabetes care can be optimized in terms of precision and clinical outcomes for the individual and U.S. population as a whole.Lay AbstractThe American Association of Clinical Endocrinologists (AACE) has created a diabetes care model for patients of different backgrounds. AACE led meetings in New York, Houston, and Miami with health care professionals and community leaders to improve diabetes care. Information from these meetings looked at biological and environmental diabetes risks. Four American patient groups were studied: African Americans, Latinos, Asian Americans, and Native Americans. Diabetes care should use culturally appropriate language and search for better ways to apply science and clinic design. Talking to patients more clearly can improve their diabetes control. There are many other needed changes in the American health care system discussed in this paper. It is hoped that through better education, research, and practice, diabetes care can be improved for the entire U.S. population. This means that important differences among patients' ethnic and cultural backgrounds are addressed.Executive Summary

• Cultural adaptation of evidence-based recommendations is a necessary component of optimal diabetes care.
• Biological factors that contribute to the pathophysiology of diabetes vary according to race and ethnicity and can be affected by social determinants that vary with culture.
• The “Transcultural Diabetes Nutrition Algorithm” was developed in 2010 to optimize diabetes nutrition care globally and represents a validated methodology where evidence-based recommendations from a source culture can be adapted and implemented in a different culture using a toolkit.
• The 2015 AACE Pan-American Workshop examined diabetes care in 9 Latin American nations and concluded that there should only be one level of diabetes care for a population and that level should be “excellent;” also, that A1C measurements should be utilized and that more educational and nutritional options are needed to optimize diabetes care.
• The “Diabetes Care Across America – A Series of Transcultural Summits” was an AACE program conducted in 2017 in New York, Houston, and Miami to examine cultural factors that influence diabetes care domestically; the findings of this program are presented here.
• The African American, Hispanic/Latino, Asian American, and Native American populations are each comprised of different ancestries, anthropometrics/body compositions and physical appearances, and cultures and degrees of acculturation, with a significant evidence base that associates specific gene variants with specific phenotypic traits affecting diabetes care.
• For each ethno-cultural population, health messaging and diabetes care will need to consider issues of potential distrust of health care professionals, history of discrimination, religious practices, food preferences, attitudes toward physical activity, and despite the full range of socio-economics, the impact of poverty on engagement, self-monitoring, adherence with lifestyle and medical recommendations, and recruitment for clinical trials.
• Diabetes care should be as precise as possible, incorporating clinical trial evidence that best reflects the ethno-cultural attributes of a specific patient, with particular emphasis on cardiovascular disease risk mitigation, technology to assess the effects of eating patterns on glycemic status, adjusting traditional eating patterns to more healthy options that are still acceptable to the patient, flexibility in lifestyle and medication recommendations that take into account cultural factors, and the utilization of community-based resources to improve implementation.
• Pragmatic first steps to prepare a diabetes practice for an ethno-culturally diverse patient population include: learning more about biological-cultural interactions; gaining experience with lifestyle and behavioral medicine, especially motivational interviewing; creating a safe and immersive clinical environment; incorporating translation services, social prescribing, wearable technologies, web-based resources, and community engagement; and establishing referral networks with clinical trialists in diabetes research to improve recruitment of different populations.

Clinical Practice Guidelines for Hypothyroidism in Adults: Cosponsored by the American Association of Clinical Endocrinologists and the American Thyroid Association

ObjectiveHypothyroidism has multiple etiologies and manifestations. Appropriate treatment requires an accurate diagnosis and is influenced by coexisting medical conditions. This paper describes evidence-based clinical guidelines for the clinical management of hypothyroidism in ambulatory patients.MethodsThe development of these guidelines was commissioned by the American Association of Clinical Endocrinologists (AACE) in association with American Thyroid Association (ATA). AACE and the ATA assem bled a task force of expert clinicians who authored this article. The authors examined relevant literature and took an evidence-based medicine approach that incor porated their knowledge and experience to develop a series of specific recommendations and the rationale for these recommendations. The strength of the recommen dations and the quality of evidence supporting each was rated according to the approach outlined in the American Association of Clinical Endocrinologists Protocol for Standardized Production of Clinical Guidelines—2010 update.ResultsTopics addressed include the etiology, epide miology, clinical and laboratory evaluation, management, and consequences of hypothyroidism. Screening, treatment of subclinical hypothyroidism, pregnancy, and areas for future research are also covered.ConclusionsFifty-two evidence-based recommenda tions and subrecommendations were developed to aid in the care of patients with hypothyroidism and to share what the authors believe is current, rational, and optimal medi cal practice for the diagnosis and care of hypothyroidism. A serum thyrotropin is the single best screening test for primary thyroid dysfunction for the vast majority of outpa tient clinical situations. The standard treatment is replace ment with L-thyroxine. The decision to treat subclinical hypothyroidism when the serum thyrotropin is less than 10 mIU/L should be tailored to the individual patient.     

Protocol for Development of American Association of Clinical Endocrinology Clinical Practice Guidelines and Consensus Statements: Summary of Methodology,Process, and Policy – 2023 Update

ObjectiveThis 2023 updated protocol summarizes the American Association of Clinical Endocrinology’s (AACE’s) new framework for the development of clinical practice guidelines and other guidance documents that includes changes to methodology, processes, and policies.MethodsAACE has critically reviewed its development processes for guidance documents over the last several years against the National Academy of Medicine Standards for Developing Trustworthy Clinical Practice Guidelines and the Council of Medical Specialty Societies Principles for Development of Specialty Society Clinical Guidelines to determine areas for improvement.ResultsThe new AACE framework for development of guidance documents incorporates many changes, including a revised conflicts of interest (COI) policy; strengthened commitment to collection of disclosures and management of relevant COI during development; open calls to membership for authors; new requirements for authors; new diversity, equity, and inclusion (DEI) policy; new empanelment process that incorporates consideration of DEI; and adoption of the Grading of Recommendations Assessment, Development and Evaluation (GRADE) methodology to increase the quality of evidence assessment and standardize recommendation grades and statements, among other improvements.ConclusionsAACE has revised its policies and adopted a completely new methodology for guideline development in support of the mission to elevate the practice of clinical endocrinology to improve patient care. With the use of an evidence-based medicine framework and by continually assessing and improving its processes for development of guidance, AACE strives to deliver trustworthy, unbiased, and up-to-date information that ensures clinician and patient confidence in AACE content. Further, AACE hopes that these enhancements foster a more collaborative approach to development and increase engagement with the worldwide medical community to improve global health.     

American Association of Clinical Endocrinologists/American College of Endocrinology Clinical Practice Guidelines for the Diagnosis and Treatment of Postmenopausal Osteoporosis— 2020 Update Executive Summary

Objective: The development of these guidelines is sponsored by the American Association of Clinical Endocrinologists (AACE) Board of Directors and American College of Endocrinology (ACE) Board of Trustees and adheres with published AACE protocols for the standardized production of clinical practice guidelines (CPGs).Methods: Recommendations are based on diligent reviews of the clinical evidence with transparent incorporation of subjective factors, according to established AACE/ACE guidelines for guidelines protocols.Results: The Executive Summary of this 2020 updated guideline contains 52 recommendations: 21 Grade A (40%), 24 Grade B (46%), 7 Grade C (14%), and no Grade D (0%). These detailed, evidence-based recommendations allow for nuance-based clinical decision-making that addresses multiple aspects of real-world care of patients. The evidence base presented in the subsequent Appendix provides relevant supporting information for the Executive Summary recommendations. This update contains 368 citations: 123 (33.5%) evidence level (EL) 1 (highest), 132 (36%) EL 2 (intermediate), 20 (5.5%) EL 3 (weak), and 93 (25%) EL 4 (lowest). New or updated topics in this CPG include: clarification of the diagnosis of osteoporosis, stratification of the patient according to high-risk and very-high-risk features, a new dual-action therapy option, and transitions from therapeutic options.Conclusion: This guideline is a practical tool for endocrinologists, physicians in general, regulatory bodies, health-related organizations, and interested laypersons regarding the diagnosis, evaluation, and treatment of post-menopausal osteoporosis.     

Expert Roundtable on Continuous Glucose Monitoring

ObjectiveThe objective of this study was to define an expert opinion on continuous glucose monitoring (CGM) in persons with type 2 diabetes mellitus, including its advantages, barriers, and best clinical practices for initiation, patient-clinician communication, and data management.MethodsA series of virtual discussions was held to recommend improvements to clinical practice and design clinical tools for primary care clinicians. Participants included endocrinologists, primary care physicians, physician assistants, advanced practice nurses, and diabetes care and education specialists.ResultsThe expert panels recommended CGM as a supplement to blood glucose monitoring and hemoglobin A1c for managing diabetes in persons with diabetes (PWDs). CGM can help predict potential pitfalls in glycemic management, including hypo and hyperglycemic excursions, which directly influence lifestyle changes, medication initiation, and dosing decisions. A toolkit was designed with practical guidance on the integration of CGM into clinical practice, interpretation of results, clinical guidelines, a patient action plan, and other useful management tools.ConclusionThis review summarizes the findings from a roundtable discussion with endocrinology and primary care clinicians, a discussion of the advantages and challenges of CGM, and clinical approaches to improving the care of PWDs. CGM offers more detailed tracking of glucose levels than blood glucose monitoring or hemoglobin A1c, and it can detect asymptomatic hypoglycemia. Specialized education of providers, the cost to patients and providers, and data management are barriers to the widespread adoption of CGM for PWDs.     

American Association of Clinical Endocrinology Consensus Statement: Addressing Stigma and Bias in the Diagnosis and Management of Patients with Obesity/Adiposity-Based Chronic Disease and Assessing Bias and Stigmatization as Determinants of Disease Severity

ObjectiveTo focus on the intersection of perception, diagnosis, stigma, and weight bias in the management of obesity and obtain consensus on actionable steps to improve care provided for persons with obesity.MethodsThe American Association of Clinical Endocrinology (AACE) convened a consensus conference of interdisciplinary health care professionals to discuss the interplay between the diagnosis of obesity using adiposity-based chronic disease (ABCD) nomenclature and staging, weight stigma, and internalized weight bias (IWB) with development of actionable guidance to aid clinicians in mitigating IWB and stigma in that context.ResultsThe following affirmed and emergent concepts were proposed: (1) obesity is ABCD, and these terms can be used in differing ways to communicate; (2) classification categories of obesity should have improved nomenclature across the spectrum of body mass index (BMI) using ethnic-specific BMI ranges and waist circumference (WC); (3) staging the clinical severity of obesity based on the presence and severity of ABCD complications may reduce weight-centric contribution to weight stigma and IWB; (4) weight stigma and internalized bias are both drivers and complications of ABCD and can impair quality of life, predispose to psychological disorders, and compromise the effectiveness of therapeutic interventions; (5) the presence and of stigmatization and IWB should be assessed in all patients and be incorporated into the staging of ABCD severity; and (6) optimal care will necessitate increased awareness and the development of educational and interventional tools for health care professionals that address IWB and stigma.ConclusionsThe consensus panel has proposed an approach for integrating bias and stigmatization, psychological health, and social determinants of health in a staging system for ABCD severity as an aid to patient management. To effectively address stigma and IWB within a chronic care model for patients with obesity, there is a need for health care systems that are prepared to provide evidence-based, person-centered treatments; patients who understand that obesity is a chronic disease and are empowered to seek care and participate in behavioral therapy; and societies that promote policies and infrastructure for bias-free compassionate care, access to evidence-based interventions, and disease prevention.     

Guideline Compliance in Chronic Heart Failure Patients with Multiple Comorbid Diseases: Evaluation of an Individualised Multidisciplinary Model of Care

Objective

To assess the impact of individualised, reconciled evidence-based recommendations (IRERs) and multidisciplinary care in patients with chronic heart failure (CHF) on clinical guideline compliance for CHF and common comorbid conditions.

Design and setting

A retrospective hospital clinical audit conducted between 1^st July 2006 and February 2011.

Participants

A total of 255 patients with a diagnosis of CHF who attended the Multidisciplinary Ambulatory Consulting Services (MACS) clinics, at the Royal Adelaide Hospital, were included.

Main outcome measures

Compliance with Australian clinical guideline recommendations for CHF, atrial fibrillation, diabetes mellitus and ischaemic heart disease.

Results

Study participants had a median of eight medical conditions (IQR 6–10) and were on an average of 10 (±4) unique medications. Compliance with clinical guideline recommendations for pharmacological therapy for CHF, comorbid atrial fibrillation, diabetes or ischaemic heart disease was high, ranging from 86% for lipid lowering therapy to 98% anti-platelet agents. For all conditions, compliance with lifestyle recommendations was lower than pharmacological therapy, ranging from no podiatry reviews for CHF patients with comorbid diabetes to 75% for heart failure education. Concordance with many guideline recommendations was significantly associated if the patient had IRERs determined, a greater number of recommendations, more clinic visits or if patients participated in a heart failure program.

Conclusions

Despite the high number of comorbid conditions and resulting complexity of the management, high compliance to clinical guideline recommendations was associated with IRER determination in older patients with CHF. Importantly these recommendations need to be communicated to the patient’s general practitioner, regularly monitored and adjusted at clinic visits.

Bariatric Surgery and the Role of the Clinical Endocrinologist: 2011 Update

ObjectiveTo discuss the emerging roles of bariatric surgery and clinical endocrinology within the context of obesity and diabetes mellitus comprehensive care plans and cost-effective strategies.MethodsRelevant literature is reviewed and clinical cases are presented.ResultsThe global obesity epidemic poses many challenges to clinical endocrinologists and has fomented a coordinated effort among specialists to revolutionize management paradigms. Technologic innovation drives the need for accelerated learning and research efforts in bariatric surgery. The national shortage of physicians with expertise in nutritional medicine compounds the management problems for this expanding patient population. Certain issues merit continued attention and research, such as gastric banding for mild obesity, surgery for treatment of diabetes, sleeve gastrectomy, and nutritional and metabolic consequences.ConclusionClinical endocrinologists should have a central role in the perioperative decision-making for patients undergoing bariatric surgery.

Dysglycemia-Based Chronic Disease: An American Association of Clinical Endocrinologists Position Statement

The American Association of Clinical Endocrinologists (AACE) has created a dysglycemia-based chronic disease (DBCD) multimorbidity care model consisting of four distinct stages along the insulin resistance-prediabetes-type 2 diabetes (T2D) spectrum that are actionable in a preventive care paradigm to reduce the potential impact of T2D, cardiometabolic risk, and cardiovascular events. The controversy of whether there is value, cost-effectiveness, or clinical benefit of diagnosing and/or managing the prediabetes state is resolved by regarding the problem, not in isolation, but as an intermediate stage in the continuum of a progressive chronic disease with opportunities for multiple concurrent prevention strategies. In this context, stage 1 represents “insulin resistance,” stage 2 “prediabetes,” stage 3 “type 2 diabetes,” and stage 4 “vascular complications.” This model encourages earliest intervention focusing on structured lifestyle change. Further scientific research may eventually reclassify stage 2 DBCD prediabetes from a predisease to a true disease state. This position statement is consistent with a portfolio of AACE endocrine disease care models, including adiposity-based chronic disease, that prioritize patient-centered care, evidence-based medicine, complexity, multimorbid chronic disease, the current health care environment, and a societal mandate for a higher value attributed to good health. Ultimately, transformative changes in diagnostic coding and reimbursement structures for prediabetes and T2D can provide improvements in population-based endocrine health care.Abbreviations: A1C = hemoglobin A1c; AACE = American Association of Clinical Endocrinologists; ABCD = adiposity-based chronic disease; CVD = cardiovascular disease; DBCD = dysglycemia-based chronic disease; FPG = fasting plasma glucose; GLP-1 = glucagon-like peptide-1; MetS = metabolic syndrome; T2D = type 2 diabetes

American Association of Clinical Endocrinologists and American College of Endocrinology Guidelines for Management of Growth Hormone Deficiency in Adults and Patients Transitioning from Pediatric to Adult Care

Objective: The development of these guidelines is sponsored by the American Association of Clinical Endocrinologists (AACE) Board of Directors and American College of Endocrinology (ACE) Board of Trustees and adheres with published AACE protocols for the standardized production of clinical practice guidelines (CPG).Methods: Recommendations are based on diligent reviews of clinical evidence with transparent incorporation of subjective factors, according to established AACE/ACE guidelines for guidelines protocols.Results: The Executive Summary of this 2019 updated guideline contains 58 numbered recommendations: 12 are Grade A (21%), 19 are Grade B (33%), 21 are Grade C (36%), and 6 are Grade D (10%). These detailed, evidence-based recommendations allow for nuance-based clinical decision-making that addresses multiple aspects of real-world care of patients. The evidence base presented in the subsequent Appendix provides relevant supporting information for the Executive Summary recommendations. This update contains 357 citations of which 51 (14%) are evidence level (EL) 1 (strong), 168 (47%) are EL 2 (intermediate), 61 (17%) are EL 3 (weak), and 77 (22%) are EL 4 (no clinical evidence).Conclusion: This CPG is a practical tool that practicing endocrinologists and regulatory bodies can refer to regarding the identification, diagnosis, and treatment of adults and patients transitioning from pediatric to adult-care services with growth hormone deficiency (GHD). It provides guidelines on assessment, screening, diagnostic testing, and treatment recommendations for a range of individuals with various causes of adult GHD. The recommendations emphasize the importance of considering testing patients with a reasonable level of clinical suspicion of GHD using appropriate growth hormone (GH) cut-points for various GH–stimulation tests to accurately diagnose adult GHD, and to exercise caution interpreting serum GH and insulin-like growth factor-1 (IGF-1) levels, as various GH and IGF-1 assays are used to support treatment decisions. The intention to treat often requires sound clinical judgment and careful assessment of the benefits and risks specific to each individual patient. Unapproved uses of GH, long-term safety, and the current status of long-acting GH preparations are also discussed in this document.LAY ABSTRACTThis updated guideline provides evidence-based recommendations regarding the identification, screening, assessment, diagnosis, and treatment for a range of individuals with various causes of adult growth-hormone deficiency (GHD) and patients with childhood-onset GHD transitioning to adult care. The update summarizes the most current knowledge about the accuracy of available GH–stimulation tests, safety of recombinant human GH (rhGH) replacement, unapproved uses of rhGH related to sports and aging, and new developments such as long-acting GH preparations that use a variety of technologies to prolong GH action. Recommendations offer a framework for physicians to manage patients with GHD effectively during transition to adult care and adulthood. Establishing a correct diagnosis is essential before consideration of replacement therapy with rhGH. Since the diagnosis of GHD in adults can be challenging, GH–stimulation tests are recommended based on individual patient circumstances and use of appropriate GH cut-points. Available GH–stimulation tests are discussed regarding variability, accuracy, reproducibility, safety, and contraindications, among other factors. The regimen for starting and maintaining rhGH treatment now uses individualized dose adjustments, which has improved effectiveness and reduced reported side effects, dependent on age, gender, body mass index, and various other individual characteristics. With careful dosing of rhGH replacement, many features of adult GHD are reversible and side effects of therapy can be minimized. Scientific studies have consistently shown rhGH therapy to be beneficial for adults with GHD, including improvements in body composition and quality of life, and have demonstrated the safety of short- and long-term rhGH replacement.Abbreviations: AACE = American Association of Clinical Endocrinologists; ACE = American College of Endocrinology; AHSG = alpha-2-HS-glycoprotein; AO-GHD = adult-onset growth hormone deficiency; ARG = arginine; BEL = best evidence level; BMD = bone mineral density; BMI = body mass index; CI = confidence interval; CO-GHD = childhood-onset growth hormone deficiency; CPG = clinical practice guideline; CRP = C-reactive protein; DM = diabetes mellitus; DXA = dual-energy X-ray absorptiometry; EL = evidence level; FDA = Food and Drug Administration; FD-GST = fixed-dose glucagon stimulation test; GeNeSIS = Genetics and Neuroendocrinology of Short Stature International Study; GH = growth hormone; GHD = growth hormone deficiency; GHRH = growth hormone–releasing hormone; GST = glucagon stimulation test; HDL = high-density lipoprotein; HypoCCS = Hypopituitary Control and Complications Study; IGF-1 = insulin-like growth factor-1; IGFBP = insulin-like growth factor–binding protein; IGHD = isolated growth hormone deficiency; ITT = insulin tolerance test; KIMS = Kabi International Metabolic Surveillance; LAGH = long-acting growth hormone; LDL = low-density lipoprotein; LIF = leukemia inhibitory factor; MPHD = multiple pituitary hormone deficiencies; MRI = magnetic resonance imaging; P-III-NP = procollagen type-III amino-terminal pro-peptide; PHD = pituitary hormone deficiencies; QoL = quality of life; rhGH = recombinant human growth hormone; ROC = receiver operating characteristic; RR = relative risk; SAH = subarachnoid hemorrhage; SDS = standard deviation score; SIR = standardized incidence ratio; SN = secondary neoplasms; T3 = triiodothyronine; TBI = traumatic brain injury; VDBP = vitamin D-binding protein; WADA = World Anti-Doping Agency; WB-GST = weight-based glucagon stimulation test     

Endocrine Follow-up During Post-Acute COVID-19: Practical Recommendations Based on Available Clinical Evidence

ObjectiveCOVID-19 affects multiple endocrine organ systems during the disease course. However, follow-up data post-COVID-19 is scarce; hitherto available limited data suggest that most of the biochemical endocrine dysfunctions observed during acute phase of COVID-19 tend to improve after recovery. Hence, we aim to provide a rational approach toward endocrine follow-up of patients during post-acute COVID-19.MethodsWe performed a literature review across PubMed/MEDLINE database looking into the effects of COVID-19 on endocrine system and subsequent long-term endocrine sequelae. Accordingly, we have presented a practical set of recommendations regarding endocrine follow-up post-acute COVID-19.ResultsCOVID-19 can lead to new-onset hyperglycemia/diabetes mellitus or worsening of dysglycemia in patients with preexisting diabetes mellitus. Hence, those with preexisting diabetes mellitus should ensure optimum glycemic control in the post-COVID-19 period. New-onset diabetes mellitus has been described post-acute COVID-19; hence, a selected group of patients (aged <70 years and those requiring intensive care unit admission) may be screened for the same at 3 months. Thyroid dysfunction (euthyroid sick syndrome and atypical thyroiditis) and adrenal insufficiency have been described in COVID-19; however, thyroid/adrenal functions usually normalize on follow-up; hence, widespread screening post-acute COVID-19 should not be recommended. Pituitary apoplexy and male hypogonadism have rarely been documented in COVID-19; therefore, appropriate follow-up may be undertaken as per clinical context. Hypocalcemia during COVID-19 is not uncommon; however, routine estimation of serum calcium post-COVID-19 is not warranted.ConclusionThe recommendations herein provide a rational approach that would be expected to guide physicians to better delineate and manage the endocrine sequelae during post-acute COVID-19.

目的:对比分析膀胱尿路上皮肿瘤合并2型糖尿病患者的临床和病理特点,为临床诊疗工作提供一定的参考。方法:回顾性分析2015年1月至2019年2月于我院泌尿外科手术治疗且经病理确诊为原发性膀胱尿路上皮肿瘤的患者资料,合并2型糖尿病的膀胱肿瘤患者59例设为糖尿病组(T2DM组),根据性别和年龄按照1:2的比例匹配同时期未合并2型糖尿病的膀胱肿瘤118例患者为非糖尿病组(NT2DM组),比较两组患者的临床特征和病理特点。结果:T2DM组的高血压患者比例和血肌酐值高于NT2DM组(P<0.05),而在教育程度、吸烟、饮酒、BMI、前列腺增生、泌尿系感染、血常规、肝功、尿常规、肿瘤大小、数量方面无明显统计学差异(P>0.05)。T2DM组和NT2DM组在膀胱尿路上皮肿瘤良恶性分类、肿瘤数量、肿瘤大小的构成比上无明显统计学差异(P>0.05);然而,对膀胱恶性肿瘤患者进行亚组分析显示,T2DM亚组中肌层浸润性癌的比例和高级别癌的比例明显高于NT2DM亚组,差异有统计学意义(P<0.05)。结论:2型糖尿病可能使膀胱癌的病理分级和分期更高,导致患者预后更差,临床上应更加关注膀胱恶性肿瘤合并2型糖尿病患者的诊治。     

Transculturalization Recommendations For Developing Latin American Clinical Practice Algorithms In Endocrinology Proceedings Of The 2015 Pan-American Workshop By The American Association Of Clinical Endocrinologists And American College Of Endocrinology

The American Association of Clinical Endocrinologists (AACE) and American College of Endocrinology (ACE) convened their first Workshop for recommendations to optimize Clinical Practice Algorithm (CPA) development for Latin America (LA) in diabetes (focusing on glycemic control), obesity (focusing on weight loss), thyroid (focusing on thyroid nodule diagnostics), and bone (focusing on postmenopausal osteoporosis) on February 28, 2015, in San Jose, Costa Rica. A standardized methodology is presented incorporating various transculturalization factors: resource availability (including imaging equipment and approved pharmaceuticals), health care professional and patient preferences, lifestyle variables, socio-economic parameters, web-based global accessibility, electronic implementation, and need for validation protocols. A standardized CPA template with node-specific recommendations to assist the local transculturalization process is provided. Participants unanimously agreed on the following five overarching principles for LA: (1) there is only one level of optimal endocrine care, (2) hemoglobin A1C should be utilized at every level of diabetes care, (3) nutrition education and increased pharmaceutical options are necessary to optimize the obesity care model, (4) quality neck ultrasound must be part of an optimal thyroid nodule care model, and (5) more scientific evidence is needed on osteoporosis prevalence and cost to justify intervention by governmental health care authorities. This 2015 AACE/ACE Workshop marks the beginning of a structured activity that assists local experts in creating culturally sensitive, evidence-based, and easy-to-implement tools for optimizing endocrine care on a global scale.Abbreviations:A1C = glycated hemoglobinAACE = American Association of Clinical EndocrinologistsACE = American College of EndocrinologyBG = blood glucoseBMI = body mass indexCPA = Clinical Practice AlgorithmCPG = Clinical Practice GuidelineCVD = cardiovascular diseaseDXA = dual-energy X-ray absorptiometryEDC = endocrine-disrupting compoundFBG = fasting blood glucoseFNA = fine-needle aspirationHCP = health care professionalLA = Latin AmericaPAACE = Pan-American AACESU = sulfonylureaT2D = type 2 diabetestDNA = transcultural Diabetes Nutrition AlgorithmTSH = thyroid-stimulating hormoneWC = waist circumferenceWHO = World Health Organization     

A Computer-Interpretable Version of the AACE,AME, ETA Medical Guidelines for Clinical Practice for the Diagnosis and Management of Thyroid Nodules

ObjectiveClinical practice guidelines (CPGs) could have a more consistent and meaningful impact on clinician behavior if they were delivered as electronic algorithms that provide patient-specific advice during patient-physician encounters. We developed a computer-interpretable algorithm for U.S. and European users for the purpose of diagnosis and management of thyroid nodules that is based on the “AACE, AME, ETA Medical Guidelines for Clinical Practice for the Diagnosis and Management of Thyroid Nodules,” a narrative, evidence-based CPG.MethodsWe initially employed the guideline-modeling language GuideLine Interchange Format, version 3, known as GLIF3, which emphasizes the organization of a care algorithm into a flowchart. The flowchart specified the sequence of tasks required to evaluate a patient with a thyroid nodule. PROforma, a second guideline-modeling language, was then employed to work with data that are not necessarily obtained in a rigid flowchart sequence. Tallis—a user-friendly web-based “enactment tool”— was then used as the “execution engine” (computer program). This tool records and displays tasks that are done and prompts users to perform the next indicated steps. The development process was iteratively performed by clinical experts and knowledge engineers.ResultsWe developed an interactive web-based electronic algorithm that is based on a narrative CPG. This algorithm can be used in a variety of regions, countries, and resource-specific settings.ConclusionElectronic guidelines provide patient-specific decision support that could standardize care and potentially improve the quality of care. The “demonstrator” electronic thyroid nodule guideline that we describe in this report is available at http://demos.deontics.com/ trace-review-app (username: reviewer; password: tnodule1). The demonstrator must be more extensively “trialed” before it is recommended for routine use. (Endocr Pract. 2014;20:352-359)     

2型糖尿病患者血糖漂移水平与动脉脉搏波速度的相关性研究

目的:研究2型糖尿病患者血糖漂移水平与动脉脉搏波速度的关系。方法:共入选82例2型糖尿病患者作为研究对象。所有研究对象应用自动脉搏波速度测定仪测定颈动脉-股动脉脉搏波速度(CFPw V);采用动态血糖检测系统(CGMS)及全自动生化分析仪进行检测,收集空腹血糖(FBG)、餐后2小时血糖(2hPG)、糖化血红蛋白(HbA1c)、血糖水平标准差(SDBG)、平均血糖波动幅度(MAGE)、最大血糖波动幅度(LAGE)、昼间血糖漂移幅度(MODD)等血糖参数。根据CGMS检测结果将82例2型糖尿病患者分为血糖低漂移组(47例)和血糖高漂移组(35例),比较两组中各血糖参数及CFPw V水平,计算两组动脉硬化发生率,并将各血糖参数与CFPw V进行Pearson相关性分析。结果:与血糖低漂移组比较,2hPG、SDBG、MAGE、LAGE、MODD、CFPw V在血糖高漂移组中升高(P0.05);血糖高漂移组中动脉硬化的发生率高于血糖低漂移组(P0.05);Pearson相关性分析分析显示2hPG、MAGE、LAGE、MODD与CFPw V相关(P0.05)。结论:本研究中,82例2型糖尿病患者存在不同程度的动脉硬化;2hPG、MAGE、LAGE、MODD是2型糖尿病患者CFPw V升高的相关因素,提示血糖漂移进一步加重动脉硬化,参与动脉硬化的发生发展。应该重视对血糖漂移的控制,减少动脉硬化的发生率,延缓动脉硬化的发展。
