Evolution of interconsultal activity to endocrinology and nutrition in hospitalization floor in a third level hospital.

INTRODUCTION: Endocrinology and Nutrition (EyN) is an outpatient and hospital medical specialty. This study aims to understand the evolution of the activity of interdepartmental consultation (IC) carried out by EyN in hospitalization floor of a third level hospital, comparing its evolution with other medical specialties, and comparing endocrine IC with nutritional IC. MATERIAL AND METHODS: Longitudinal and retrospective study which analyzes IC notes of EyN and other medical specialties between 01-01-2013 and 31-12-2022. RESULTS: A total of 76093 IC notes (12623 patients) were performed by the EyN service (average age 65.4 years; 59% male) with an average of 4.8 notes per patient. Average annual growth was 7% in notes and 4% in patients (versus 6% and 3% of all other medical services, differences statistically significant). Of all patients hospitalized for 4 or more days, EyN went from attending 7.9% (2013) to 12.3% (2022). 66% of the IC performed by EyN was for nutritional cause and 34% for other pathologies. CONCLUSIONS: The EyN service is the one that most patients attend in hospital IC activity, with growth over the last few years greater than other medical specialties. Nutritional pathology is the main reason for IC.

European Society of Endocrinology and Endocrine Society Joint Clinical Guideline: Diagnosis and therapy of glucocorticoid-induced adrenal insufficiency.

Glucocorticoids are widely prescribed as anti-inflammatory and immunosuppressive agents. This results in at least 1% of the population using chronic glucocorticoid therapy, being at risk for glucocorticoid-induced adrenal insufficiency. This risk is dependent on the dose, duration and potency of the glucocorticoid, route of administration, and individual susceptibility. Once glucocorticoid-induced adrenal insufficiency develops or is suspected, it necessitates careful education and management of affected patients. Tapering glucocorticoids can be challenging when symptoms of glucocorticoid withdrawal develop, which overlap with those of adrenal insufficiency. In general, tapering of glucocorticoids can be more rapidly within a supraphysiological range, followed by a slower taper when on physiological glucocorticoid dosing. The degree and persistence of HPA axis suppression after cessation of glucocorticoid therapy are dependent on overall exposure and recovery of adrenal function varies greatly amongst individuals. This first European Society of Endocrinology/Endocrine Society joint clinical practice guideline provides guidance on this clinically relevant condition to aid clinicians involved in the care of patients on chronic glucocorticoid therapy.

Diagnosis, treatment, and management of rickets: a position statement from the Bone and Mineral Metabolism Group of the Italian Society of Pediatric Endocrinology and Diabetology.

Rickets results from impaired mineralization of growing bone due to alterations in calcium and phosphate homeostasis. Clinical signs of rickets are related to the age of the patient, the duration of the disease, and the underlying disorder. The most common signs of rickets are swelling of the wrists, knees or ankles, bowing of the legs (knock-knees, outward bowing, or both) and inability to walk. However, clinical features alone cannot differentiate between the various forms of rickets. Rickets includes a heterogeneous group of acquired and inherited diseases. Nutritional rickets is due to a deficiency of vitamin D, dietary calcium or phosphate. Mutations in genes responsible for vitamin D metabolism or function, the production or breakdown of fibroblast growth factor 23, renal phosphate regulation, or bone mineralization can lead to the hereditary form of rickets. This position paper reviews the relevant literature and presents the expertise of the Bone and Mineral Metabolism Group of the Italian Society of Pediatric Endocrinology and Diabetology (SIEDP). The aim of this document is to provide practical guidance to specialists and healthcare professionals on the main criteria for diagnosis, treatment, and management of patients with rickets. The various forms of rickets are discussed, and detailed references for the discussion of each form are provided. Algorithms to guide the diagnostic approach and recommendations to manage patients with rare forms of hereditary rickets are proposed.

Familial hyperaldosteronism: an European Reference Network on Rare Endocrine Conditions clinical practice guideline.

We describe herein the European Reference Network on Rare Endocrine Conditions clinical practice guideline on diagnosis and management of familial forms of hyperaldosteronism. The guideline panel consisted of 10 experts in primary aldosteronism, endocrine hypertension, paediatric endocrinology, and cardiology as well as a methodologist. A systematic literature search was conducted, and because of the rarity of the condition, most recommendations were based on expert opinion and small patient series. The guideline includes a brief description of the genetics and molecular pathophysiology associated with each condition, the patients to be screened, and how to screen. Diagnostic and treatment approaches for patients with genetically determined diagnosis are presented. The recommendations apply to patients with genetically proven familial hyperaldosteronism and not to families with more than one case of primary aldosteronism without demonstration of a responsible pathogenic variant.

Tackling access and payer barriers for growth hormone therapy in Saudi Arabia: a consensus statement for the Saudi Working Group for Pediatric Endocrinology.

Prompt diagnosis and early treatment are key goals to optimize the outcomes of children with growth hormone deficiency (GHD) and attain the genetically expected adult height. Nonetheless, several barriers can hinder prompt diagnosis and treatment of GHD, including payer-related issues. In Saudi Arabia, moderate-to-severe short stature was reported in 13.1 and 11.7 % of healthy boys and girls, respectively. Several access and payer barriers can face pediatric endocrinologists during the diagnosis and treatment of GHD in Saudi Arabia. Insurance coverage policies can restrict access to diagnostic tests for GHD and recombinant human growth hormone (rhGH) due to their high costs and lack of gold-standard criteria. Some insurance policies may limit the duration of treatment with rhGH or the amount of medication covered per month. This consensus article gathered the insights of pediatric endocrinologists from Saudi Arabia to reflect the access and payer barriers to the diagnostic tests and treatment options of children with short stature. We also discussed the current payer-related challenges endocrinologists face during the investigations of children with short stature. The consensus identified potential strategies to overcome these challenges and optimize patient management.

A longitudinal study of endocrinology and foraging ecology of subadult gray whales prior to death based on baleen analysis.

Individual-level assessments of wild animal health, vital rates, and foraging ecology are critical for understanding population-wide impacts of exposure to stressors. Large whales face multiple stressors, including, but not limited to, ocean noise, pollution, and ship strikes. Because baleen is a continuously growing keratinized structure, serial extraction, and quantification of hormones and stable isotopes along the length of baleen provide a historical record of whale physiology and foraging ecology. Furthermore, baleen analysis enables the investigation of dead specimens, even decades later, allowing comparisons between historic and modern populations. Here, we examined baleen of five sub-adult gray whales and observed distinct patterns of oscillations in δ15N values along the length of their baleen plates which enabled estimation of baleen growth rates and differentiation of isotopic niche widths of the whales during wintering and summer foraging. In contrast, no regular patterns were apparent in δ13C values. Prolonged elevation of cortisol in four individuals before death indicates that chronic stress may have impacted their health and survival. Triiodothyronine (T3) increased over months in the whales with unknown causes of death, simultaneous with elevations in cortisol, but both hormones remained stable in the one case of acute death attributed to killer whale predation. This parallel elevation of cortisol and T3 challenges the classic understanding of their interaction and might relate to increased energetic demands during exposure to stressors. Reproductive hormone profiles in subadults did not show cyclical trends, suggesting they had not yet reached sexual maturity. This study highlights the potential of baleen analysis to retrospectively assess gray whales' physiological status, exposure to stressors, reproductive status, and foraging ecology in the months or years leading up to their death, which can be a useful tool for conservation diagnostics to mitigate unusual mortality events.

Endocrinology's early historians (1889-1914) and the forgotten prehistory of testosterone.

INTRODUCTION: An often-retold historical outline of endocrinology was established over a century ago. An exhaustive history of sexual physiology remains forthcoming, however. OBJECTIVES: To explore and contextualize the remarkable medical-historical and medical-anthropologic frenzy triggered by Brown-Séquard's 1889 self-injections with testicular juice, which ultimately settled down into an early history of endocrinology. METHODS: Pertinent primary sources were selected from a broader study, primarily between 1889 and 1914, as well as selected older texts identified and unidentified by these sources. RESULTS: Endocrinology's early historians in a short space of time moved from the history of testicular opotherapy to that of glandular typology and physiology and to increasingly encompassing medical-historical accounts of internal secretion as an epochal idea. Early historians nominated "precursors" to Brown-Séquard but underestimated physiologic continuities-specifically, early modern protoendocrinologic notions concerning semen as a "recrement," notions still recited by Brown-Séquard and early Brown-Séquardists as well their detractors. Brown-Séquard himself worked through this old (recremental) concept of semen between 1889 and 1892 but was later identified with it, by among others Ancel and Bouin. CONCLUSION: Western sexual physiology is a medical palimpsest, the undertexts of which remain to be studied in detail.

Cryo-electron microscopy for GPCR research and drug discovery in endocrinology and metabolism.

G protein-coupled receptors (GPCRs) are the largest family of cell surface receptors, with many GPCRs having crucial roles in endocrinology and metabolism. Cryogenic electron microscopy (cryo-EM) has revolutionized the field of structural biology, particularly regarding GPCRs, over the past decade. Since the first pair of GPCR structures resolved by cryo-EM were published in 2017, the number of GPCR structures resolved by cryo-EM has surpassed the number resolved by X-ray crystallography by 30%, reaching >650, and the number has doubled every ~0.63 years for the past 6 years. At this pace, it is predicted that the structure of 90% of all human GPCRs will be completed within the next 5-7 years. This Review highlights the general structural features and principles that guide GPCR ligand recognition, receptor activation, G protein coupling, arrestin recruitment and regulation by GPCR kinases. The Review also highlights the diversity of GPCR allosteric binding sites and how allosteric ligands could dictate biased signalling that is selective for a G protein pathway or an arrestin pathway. Finally, the authors use the examples of glycoprotein hormone receptors and glucagon-like peptide 1 receptor to illustrate the effect of cryo-EM on understanding GPCR biology in endocrinology and metabolism, as well as on GPCR-related endocrine diseases and drug discovery.

Social media's impact on patient provider choice.

OBJECTIVE: This study aimed to investigate if social media (SM) impacts a patient's provider choice in the field of reproductive endocrinology and infertility (REI). METHODS: This was a survey-based study completed in July 2022. A survey link was distributed using Amazon Mechanical Turk, which directed participants to a Qualtrics-based survey. Participants were 18-50 years old. The primary outcome was to identify the preferred method for finding a REI provider based on time spent on SM (< 1 h, 1-3 h, 3 + h). RESULTS: A total of 336 responses were analyzed. Fifty-four percent of respondents used SM < 1 h, 33.33% used 1-3 h, and 12.80% used 3 + h. The majority (69.05%) of respondents stated that they would seek out a REI provider/clinic if they had difficulty conceiving. Most respondents identified asking their primary care physician (44.64%) as the primary means for finding an REI provider/clinic and did not prefer to use SM. Although Facebook (< 1 h: 30.94%, 1-3 h: 31.25%, 3 + h: 27.91%) was the most utilized SM platform among respondents, YouTube was the preferred SM platform if respondents were to follow a REI clinic with a preference for posts focusing on education (< 1 h: 55.68%, 1-3 h: 43.12%, 3 + h: 58.14%) or stress management (< 1 h: 17.61%, 1-3 h: 29.36%, 3 + h: 20.94%). CONCLUSION: Most respondents utilize traditional methods when choosing their REI provider or clinic and would not utilize SM. However, SM, primarily through YouTube, may be helpful for educating infertility patients and providing support and stress relief while they undergo treatment.
