Deciphering the roles of triiodothyronine (T3) and thyroid-stimulating hormone (TSH) on cardiac electrical remodeling in clinical and experimental hypothyroidism. J Physiol Biochem 2024; 80:1-9. [PMID: 38019451 PMCID: PMC10808292 DOI: 10.1007/s13105-023-01000-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2023] [Accepted: 11/20/2023] [Indexed: 11/30/2023]
Abstract
Hypothyroidism is the most frequent endocrine pathology. Although clinical or overt hypothyroidism has been traditionally associated to low T3 / T4 and high thyrotropin (TSH) circulating levels, other forms exist such as subclinical hypothyroidism, characterized by normal blood T3 / T4 and high TSH. In its different forms is estimated to affect approximately 10% of the population, especially women, in a 5:1 ratio with respect to men. Among its consequences are alterations in cardiac electrical activity, especially in the repolarization phase, which is accompanied by an increased susceptibility to cardiac arrhythmias. Although these alterations have traditionally been attributed to thyroid hormone deficiency, recent studies, both clinical trials and experimental models, demonstrate a fundamental role of TSH in cardiac electrical remodeling. Thus, both metabolic thyroid hormones and TSH regulate cardiac ion channel expression in many and varied ways. This means that the different combinations of hormones that predominate in different types of hypothyroidism (overt, subclinic, primary, central) can generate different forms of cardiac electrical remodeling. These new findings are raising the relevant question of whether serum TSH reference ranges should be redefined.

The experience of diagnosis announcement in rare endocrine diseases: A survey of the French FIRENDO network. ANNALES D'ENDOCRINOLOGIE 2024; 85:27-35. [PMID: 37951412 DOI: 10.1016/j.ando.2023.10.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/13/2023] [Revised: 10/20/2023] [Accepted: 10/23/2023] [Indexed: 11/14/2023]
Abstract
CONTEXT Diagnosis announcement of a chronic disease is a crucial moment for patients as well as for their families and an important step in the management of severe conditions such as rare endocrine diseases. Little is known of how diagnosis is communicated to patients and families. The FIRENDO network was created by the third French Plan for Rare Diseases, to promote autonomy, care and research on rare endocrine diseases. OBJECTIVES The aim of this study was to characterize, for the first time, the experience and needs of patients and/or their parents around the announcement of diagnosis to ensure optimal quality of care. METHODS A quantitative self-administered survey on diagnosis announcement procedures in rare endocrine diseases was launched in April 2017 by the ad hoc FIRENDO thematic working group in collaboration with its 11 partnering patient associations and support groups. The questionnaire was designed and revised by patient support group representatives, adult and pediatric endocrinologists, psychologists and biologists, all expert in rare endocrine diseases. It was made available on the FIRENDO network website and distributed mainly by email with electronic links on their respective websites to members of all affiliated patient support groups. RESULTS Questionnaires were filled out by 391 patients and 223 parents (median age of patients: 39 years). The following conditions were associated with at least 30 answers: Addison's disease, classical forms of congenital adrenal hyperplasia (CAH), Russell-Silver syndrome, Cushing's syndrome, acromegaly and craniopharyngioma. Overall, some announcement modalities were judged favorably by patients: physician's empathy, availability and use of clear terms, and presence of family at the time of announcement. However, a lack of psychological care and information documents was reported, as well as some inadequate procedures such as postal mail announcements. CONCLUSION This work suggests that better knowledge of the patient's experience is useful for improving the diagnosis announcement of rare endocrine disorders. The main recommendations derived from the survey were the need for several announcement visits, information on patient support groups and reference centers, imperatively avoiding impersonal announcement, and the usefulness of a written accompanying document.

Abstract
Aggression is a very common behavioral problem in dogs. Although aggression can be part of the normal behavior of dogs, medical conditions can either trigger aggression as in the case of intracranial tumors or aggravate an existing aggression problem as it happens with painful conditions. Therefore, it is essential to include an assessment of physical health in the diagnostic protocol of canine aggression.

Abstract
Like many physical disorders, the clinical signs associated with metabolic diseases affecting thyroid, adrenal, and pancreatic function are reflective of nonspecific changes in behavior. Additionally, patients who have underlying disorders associated with fear, anxiety, stress, conflict, and/or panic may be under treatment with medications that alter basal thyroid, glucose, and cortisol levels. Through reinforcement and punishment of behaviors associated with clinical signs caused by organic or iatrogenic endocrine disease, behaviors can be perpetuated and become persistent patterns. Screening all patients presenting with a primary behavior complaint or those with behavioral clinical signs of endocrine diseases is essential. Alleviating stress immediately while working up or treating metabolic disease reduces suffering and may stave off the adoption of behavior patterns more permanently.

Abstract
The local prevalence of primary adrenal insufficiency (PAI) depends on various factors such as genetics, environment, and timely disease diagnosis. PAI is uncommon, and the prevalence is reported to be 2 per 10,000 population. PAI is commonly caused by an autoimmune process that destroys the adrenal gland, resulting in the loss of glucocorticoid and mineralocorticoid secretion from the adrenal cortex. The lack of cortisol results in impaired glucose/fat/protein metabolism, hypotension, increased adrenocorticotropic hormone secretion, impaired fluid excretion, and hyperpigmentation. PAI has a female predominance and is commonly seen in ages 20 to 50 years but can occur at any age.

Abstract
Chronic exposure to endogenous and exogenous glucocorticoids will cause CS. Endogenous CS is uncommon, with an annual incidence of 0.2-5 individuals per million. Endogenous causes could be 1. adrenocorticotropic hormone (ACTH) dependent or 2. ACTH independent. The use of exogenous glucocorticoids to manage chronic autoimmune or inflammatory diseases is the most common cause of CS and results in iatrogenic CS. Cushing disease is caused by excess ACTH production by a pituitary tumor. CS's clinical manifestations in the head and neck region include a moon-shaped face, acne flares, and hirsutism.

Abstract
The building of life stress, well expressed by the concept of allostatic load, plays an important part in all phases of endocrine illness. Allostatic load refers to the cumulative burden of both stressful life events and chronic stress. When environmental challenges exceed the individual ability to cope, allostatic overload ensues. Assessment of allostatic load/overload by clinical measurements including indices and rating scales, in addition to biomarkers, offers a characterization of the person's psychosocial environment that is missing from current formulations. Consideration of allostatic load in endocrinology may shed light on a number of clinical issues: interpretation of abnormal hormone values that lack explanations; coping with the various phases of illness; maladaptive illness behavior; response to treatment; presence of residual symptoms; health-damaging lifestyle habits. Addressing allostatic load calls for innovative models of endocrine outpatients with multidisciplinary organization of care, extended time for the interview, focus on rehabilitation. We provide an overview on the mechanisms of allostatic load, how it can be assessed, its potential role in endocrine disturbances, and how its consideration may lead to a needed innovation in patient care.

Abstract
The Tehran cardiometabolic genetic study (TCGS) is a large population-based cohort study that conducts periodic follow-ups. TCGS has created a comprehensive database comprising 20,367 participants born between 1911 and 2015 selected from four main ongoing studies in a family-based longitudinal framework. The study's primary goal is to identify the potential targets for prevention and intervention for non-communicable diseases that may develop in mid-life and late life. TCGS cohort focuses on cardiovascular, endocrine, metabolic abnormalities, cancers, and some inherited diseases. Since 2017, the TCGS cohort has augmented by encoding all health-related complications, including hospitalization outcomes and self-reports according to ICD11 coding, and verifying consanguineous marriage using genetic markers. This research provides an update on the rationale and design of the study, summarizes its findings, and outlines the objectives for precision medicine.

Abstract
PURPOSE To evaluate: (1) clinical and epidemiological characteristics of outpatients transitioned from Pediatrics Endocrine (PED) to Adult Endocrine Department (AED) in a tertiary center; (2) transition process features, and predictors of drop-out. METHODS Demographic, clinical, and transition features of 170 consecutive patients with pediatric onset of chronic endocrine or metabolic disease (excluded type 1 diabetes) who transitioned from PED to AED (2007-2020) were retrospective evaluated. RESULTS The age at transition was 18.4 ± 4 years (F:M = 1.2: 1), and mean follow-up 2.8 years. The population was heterogeneous; the most (69.4%) was affected by one, 24.1% by two or more endocrine diseases, 6.5% were followed as part of a cancer survivor's surveillance protocol. The comorbidity burden was high (37, 20.6, and 11.2% of patients had 2, 3, 4, or more diseases). The number of visits was associated with the number of endocrine diseases and the type of them. Adherent subjects had a higher number of comorbidities. Thyroid disorders and more than one comorbidity predicted the adherence to follow-up. Having performed one visit only was predictive of drop-out, regardless of the pathology at diagnosis. CONCLUSION This is the first study that analyzed a specific transition plan for chronic endocrine diseases on long-term follow-up. The proposed "one-size-fits-all model" is inadequate in responding to the needs of patients. A structured transition plan is an emerging cornerstone.

Abstract
INTRODUCTION Factitious thyrotoxicosis includes all causes of thyrotoxicosis from the short or long-term ingestion of thyroid hormone, of which one of the complications is atrial fibrillation. CASE PRESENTATION A woman, 71 years old, complained of chest palpitations. She had a medical history of thyroidectomy, hypertension, and dyslipidemia. In addition, she took Levothyroxine, amlodipine and simvastatin regularly. On physical examination, the general status was weak, with vital signs showing blood pressure (BP) of 170/100 mmHg, heart rate (HR) of 130-150 bpm, irregular rhythm, respiratory rate (RR) of 20×/min, axillary temperature of 36.8 °C, and oxygen saturation (SpO2) 98 % with room air. The abnormal laboratory found were significant increase in total T4, total T3, FT4, and low levels of TSH. The first electrocardiogram (ECG) showed AF and Burch Watorfsky's score was 45. The AF was treated with a loading dose of amiodarone 150 mg in 10 min and decreased gradually. She had received a high-calorie, protein and low-salt diet of 2100 kcal/day, termination Levothyroxine usage, propranolol of 10 mg/8 h, amlodipine of 5 mg/day, and lisinopril of 5 mg/day. Treatment for AF was continued with a maintenance dose of amiodarone IV 300 mg in 6 h, then 600 mg in 18 h, warfarin tablet 2 mg/day (according to treatment from a cardiologist), and atorvastatin 20 mg/day at night. After 6 days of treatment, the patient experienced improvement and continued discharge. The patient improved on an outpatient basis and was monitored periodically. DISCUSSION Monitored treatment of thyrotoxicosis and AF management with 3 principles can minimize complication severity. CONCLUSION Early, effective and monitored treatment of thyrotoxicosis is vital to manage AF in achieving a better outcome.

Abstract
Background The aim of this study was to investigate the relationship between occupational exposure to various hazards and hospital admission due to endocrine diseases in Korean male firefighters. Methods From 2000 to 2008, former and current male firefighters registered in the Korean National Emergency Management Agency were investigated based on their hospitalized health insurance admission data for the same period. Admission data for endocrine, nutritional, and metabolic diseases were obtained from the Korean National Health Insurance Service database. Standardized admission ratio (SAR) with reference to the general population of Korean men was analyzed. Results SAR for firefighters with endocrine, nutritional, and metabolic diseases was 0.56 (95% confidence interval [CI]: 0.49–0.65), which was significantly less than that of the general population of Korean men. For those with endocrine, nutritional, and metabolic diseases, SARs for those with a history of fire suppression tasks and those without experience of fire suppression tasks were 0.58 (95% CI: 0.49–0.68) and 0.53 (95% CI: 0.40–0.70), respectively. Conclusions The admission rate of Korean male firefighters due to endocrine, nutritional and metabolic diseases was significantly lower than that of the general Korean men population, the hazardous potential of endocrine disruptors remains an open question. Further studies of firefighters with longer follow-up are needed.

Abstract
Purpose The COVID-19 pandemic brought unprecedented conditions for overall health care systems by restricting resources for non-COVID-19 patients. As the burden of the disease escalates, routine elective surgeries are being cancelled. The aim of this paper was to provide a guideline for management of endocrine surgical disorders during a pandemic. Methods We used Delphi method with a nine-scale Likert scale on two rounds of voting involving 64 experienced eminent surgeons and endocrinologists who had the necessary experience to provide insight on endocrine disorder management. All voting was done by email using a standard questionnaire. Results Overall, 37 recommendations were voted on. In two rounds, all recommendations reached an agreement and were either endorsed or rejected. Endorsed statements include dietary change in primary hyperparathyroidism, Cinacalcet treatment in secondary hyperparathyroidism, alpha-blocker administration for pheochromocytoma, methimazole ± β-blocker combination for Graves’ disease, and follow-up for fine-needle aspiration results of thyroid nodules indicated as Bethesda 3–4 cytological results and papillary microcarcinoma. Conclusion This survey summarizes expert opinion for the management of endocrine surgical conditions during unprecedented times when access to surgical treatment is severely disrupted. The statements are not applicable in circumstances in which surgical treatment is possible.

Abstract
BACKGROUND Nodal involvement has been identified as one of the strongest prognostic factors in patients with nonfunctional pancreatic neuroendocrine tumors (NF-PanNETs). Sufficient lymphadenectomy and evaluation is vital for accurate staging. The purpose of this study was to identify the optimal number of examined lymph nodes (ELN) required for accurate staging. METHODS The SEER database was used to identify patients with resected NF-PanNETs between 2004 and 2014. The distributions of positive lymph nodes (PLN) ratio and total lymph nodes were used to develop a mathematical model. The sensitivity of detecting nodal disease at each cutoff of ELN was estimated and used to identify the optimal cutoff for ELN. RESULTS A total of 1098 patients were included in the study of which 391 patients (35.6%) had nodal disease. The median ELN was 12 (interquartile range [IQR]: 7-19.5), and the median PLN was 2 (IQR: 1-4) for patients with nodal disease. With an increase in ELN, the sensitivity of detecting nodal disease increased from 12.0% (ELN: 1) to 92.2% (ELN: 20), plateauing at 20 ELN (< 1% increase in sensitivity with an additional ELN). This sensitivity increase pattern was similar in subgroup analyses with different T stages. CONCLUSIONS The sensitivity of detecting nodal disease in patients with NF-PanNETs increases with an increase in the number of ELN. Cutoffs for adequate nodal assessment were defined for all T stages. Utilization of these cutoffs in clinical settings will help with patient prognostication and management.

Abstract
Clinical or pathological evidence demonstrated that air pollution could undermine other organ systems of human body besides respiratory and circulation systems. Investigations that directly relate hospital outpatient visits for endocrine (ENDO), digestive (DIGE), urological (UROL), and dermatological (DERM) diseases categories with ambient particulate matter (PM) are still lacking, particularly in heavily polluted cities. Here, we conducted a time-series analysis using 812,624, 1,111,342, 539,803, and 741,662 hospital visits for ENDO, DIGE, UROL, and DERM, respectively, in Nanjing, China from 2013 to 2019. A generalized additive model was applied to estimate the exposure-response associations. Results showed that a 10 μg/m3 increase in PM2.5 concentration on lag 0 day was significantly associated with 0.59% (95% CI: 0.30%, 0.88%), 0.43% (0.15%, 0.70%), 0.36% (0.06%, 0.66%), and 0.65% (0.42%, 0.87%) increase for ENDO, DIGE, UROL, and DERM hospital visits, respectively. The estimated effects of PM10 were slightly smaller but still statistically significant. The magnitude and significance of the associations between PM and four health outcomes were sensitive to additional adjustment for co-pollutants. Exposure-response relationships were linear for PM concentrations lower than 100 μg/m3 but the curves became nonlinear across the full range of exposures due to a flatten slope at higher concentrations. We also explored the effect modifications by season (cold or warm), age (5-18, 18-64, 65-74, or 75+ years), and sex (male or female). Results showed that the DERM-related population aged 65 years or older was more vulnerable to PM exposure, compared with the 5 to 17-year age group; the DERM-related population aged 75 years or older and 65 years or older was more vulnerable to PM2.5 and PM10 exposure, respectively, compared with the 18 to 64-year age group. Our study provided suggestive evidence that ambient PM pollution was associated with ENDO, DIGE, UROL, and DERM outpatient hospital visits in Nanjing, China.

Abstract
Disorders of the endocrine system usually manifest in a multi-organ fashion. More specifically, many endocrinopathies become apparent in the eye first through a variety of distinct pathophysiologic disturbances. The eye provides physicians with valuable clues for the recognition and management of numerous systemic diseases, including many disorders of the endocrine pathway. Recognizing ophthalmic manifestations of endocrine disorders is critical not only for rapid diagnosis and treatment, but also to prevent significant morbidity and mortality. In this review, we discuss relevant ophthalmic findings associated with key disorders of the pancreas, thyroid gland, and hypothalamic-pituitary axis, as well as with multiple hereditary endocrine syndromes. We have chosen to focus on diabetes mellitus (DM), Graves' ophthalmopathy, pituitary tumors, and some less common disorders that underscore the unique relationship between the eye and the endocrine system.

A resistance to thyroid hormone syndrome mutant operates through the target gene repertoire of the wild-type thyroid hormone receptor. Mol Cell Endocrinol 2017; 447:87-97. [PMID: 28257829 DOI: 10.1016/j.mce.2017.02.044] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/19/2016] [Revised: 02/26/2017] [Accepted: 02/27/2017] [Indexed: 10/20/2022]
Abstract
Thyroid hormone receptors (TRs) play crucial roles in vertebrates. Wild-type (WT) TRs function primarily as hormone-regulated transcription factors. A human endocrine disease, Resistance to Thyroid Hormone (RTH)-Syndrome, is caused by inheritance of mutant TRs impaired in the proper regulation of target gene expression. To better understand the molecular basis of RTH we compared the target genes regulated by an RTH-TRβ1 mutant (R429Q) to those regulated by WT-TRβ1. With only a few potential exceptions, the vast majority of genes we were able to identify as regulated by the WT-TRβ1, positively or negatively, were also regulated by the RTH-TRβ1 mutant. We conclude that the actions of R429Q-TRβ1 in RTH-Syndrome most likely reflect the reduced hormone affinity observed for this mutant rather than an alteration in target gene repertoire. Our results highlight the importance of target gene specificity in defining the disease phenotype and improve our understanding of how clinical treatments impact RTH-Syndrome.
