Abstract
PURPOSE The Pituitary Society established the concept and mostly qualitative parameters for defining uniform criteria for Pituitary Tumor Centers of Excellence (PTCOEs) based on expert consensus. Aim of the study was to validate those previously proposed criteria through collection and evaluation of self-reported activity of several internationally-recognized tertiary pituitary centers, thereby transforming the qualitative 2017 definition into a validated quantitative one, which could serve as the basis for future objective PTCOE accreditation. METHODS An ad hoc prepared database was distributed to nine Pituitary Centers chosen by the Project Scientific Committee and comprising Centers of worldwide repute, which agreed to provide activity information derived from registries related to the years 2018-2020 and completing the database within 60 days. The database, provided by each center and composed of Excel® spreadsheets with requested specific information on leading and supporting teams, was reviewed by two blinded referees and all 9 candidate centers satisfied the overall PTCOE definition, according to referees' evaluations. To obtain objective numerical criteria, median values for each activity/parameter were considered as the preferred PTCOE definition target, whereas the low limit of the range was selected as the acceptable target for each respective parameter. RESULTS Three dedicated pituitary neurosurgeons are preferred, whereas one dedicated surgeon is acceptable. Moreover, 100 surgical procedures per center per year are preferred, while the results indicated that 50 surgeries per year are acceptable. Acute post-surgery complications, including mortality and readmission rates, should preferably be negligible or nonexistent, but acceptable criterion is a rate lower than 10% of patients with complications requiring readmission within 30 days after surgery. Four endocrinologists devoted to pituitary diseases are requested in a PTCOE and the total population of patients followed in a PTCOE should not be less than 850. It appears acceptable that at least one dedicated/expert in pituitary diseases is present in neuroradiology, pathology, and ophthalmology groups, whereas at least two expert radiation oncologists are needed. CONCLUSION This is, to our knowledge, the first study to survey and evaluate the activity of a relevant number of high-volume centers in the pituitary field. This effort, internally validated by ad hoc reviewers, allowed for transformation of previously formulated theoretical criteria for the definition of a PTCOE to precise numerical definitions based on real-life evidence. The application of a derived synopsis of criteria could be used by independent bodies for accreditation of pituitary centers as PTCOEs.

Abstract
The 13th Acromegaly Consensus Conference was held in November 2019 in Fort Lauderdale, Florida, and comprised acromegaly experts including endocrinologists and neurosurgeons who considered optimal approaches for multidisciplinary acromegaly management. Focused discussions reviewed techniques, results, and side effects of surgery, radiotherapy, and medical therapy, and how advances in technology and novel techniques have changed the way these modalities are used alone or in combination. Effects of treatment on patient outcomes were considered, along with strategies for optimizing and personalizing therapeutic approaches. Expert consensus recommendations emphasize how best to implement available treatment options as part of a multidisciplinary approach at Pituitary Tumor Centers of Excellence.

Abstract
Pituitary-directed medical treatment for Cushing's disease (CD) is currently represented by membrane receptor targeting drugs (somatostatin analogs and dopamine agonists). Somatostatin and dopamine receptors are regulated by β-arrestins, which have been shown to be differentially regulated by glucocorticoids in non-neuroendocrine cells. In this study we investigated the effects of glucocorticoids on β-arrestin expression in corticotroph tumor cells. First, AtT20 cells, a mouse model of CD, were exposed to dexamethasone (Dex) at different time points and β-arrestin expression was evaluated at mRNA and protein levels. Futhermore, β-arrestin mRNA expression was evaluated in 17 human corticotroph adenoma samples and correlated to patients' pre-operative cortisol levels. We observed that Dex treatment induced a time-dependent increase in β-arrestin 1 mRNA expression and a decrease in β-arrestin 2. The same modulation pattern was observed at protein level. Dex-mediated modulation of β-arrestins was abolished by co-treatment with mifepristone, and Dex withdrawal restored β-arrestin expression to basal levels after 72 h. The evaluation of β-arrestin mRNA in corticotroph adenomas from CD patients with variable disease activity showed a significant positive correlation between β-arrestin 1 mRNA and urinary cortisol levels. The effect of glucocorticoids on β-arrestin levels was confirmed by the analysis of two samples from a single patient, which underwent adenomectomy twice, with different pre-operative cortisol levels. In conclusion, glucocorticoids induce an inverse modulation of the two β-arrestin isofoms in corticotroph tumor cells. Since β-arrestins regulate membrane receptor functions, this finding may help to better understand the variable response to pituitary-targeting drugs in patients with Cushing's disease.

Abstract
OBJECTIVE The aim of the Acromegaly Consensus Group was to revise and update the consensus on diagnosis and treatment of acromegaly comorbidities last published in 2013. PARTICIPANTS The Consensus Group, convened by 11 Steering Committee members, consisted of 45 experts in the medical and surgical management of acromegaly. The authors received no corporate funding or remuneration. EVIDENCE This evidence-based consensus was developed using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) system to describe both the strength of recommendations and the quality of evidence following critical discussion of the current literature on the diagnosis and treatment of acromegaly comorbidities. CONSENSUS PROCESS Acromegaly Consensus Group participants conducted comprehensive literature searches for English-language papers on selected topics, reviewed brief presentations on each topic, and discussed current practice and recommendations in breakout groups. Consensus recommendations were developed based on all presentations and discussions. Members of the Scientific Committee graded the quality of the supporting evidence and the consensus recommendations using the GRADE system. CONCLUSIONS Evidence-based approach consensus recommendations address important clinical issues regarding multidisciplinary management of acromegaly-related cardiovascular, endocrine, metabolic, and oncologic comorbidities, sleep apnea, and bone and joint disorders and their sequelae, as well as their effects on quality of life and mortality.

Abstract
CONTEXT Intensive insulin therapy (IIT) improved outcome in the adult and pediatric intensive care unit (PICU) compared with conventional insulin therapy (CIT). IIT did not increase the anabolic hormone IGF-I in critically ill adults, but feeding in critically ill children and pediatric hormonal responses may differ. Twenty-five percent of the children with IIT experienced hypoglycemia, which may have evoked counterregulatory responses. OBJECTIVE We hypothesized that IIT reactivates the somatotropic axis and anabolism in PICU patients. DESIGN This was a preplanned subanalysis of a randomized controlled trial on IIT. PATIENTS We studied 369 patients who stayed in PICU for at least 3 d (study 1) and 126 patients in a nested case-control study (study 2). MAIN OUTCOME MEASURES Circulating insulin, C-peptide, GH, IGF-I, bioavailable IGF-I, IGF-binding protein (IGFBP)-1, IGFBP-3, and acid-labile subunit were analyzed upon admission and d 3. In the nested case-control study, the somatotropic axis, cortisol, and glucagon were analyzed before and after hypoglycemia. RESULTS On d 3, C-peptide was more than 10-fold lower (P < 0.0001) in the IIT group than in the CIT group. IIT increased circulating GH (P = 0.04) and lowered bioavailable IGF-I (P = 0.002). IIT also decreased IGFBP-3 (P = 0.0005) and acid-labile subunit (P = 0.007), while increasing IGFBP-1 (P = 0.04) and the urea/creatinine ratio, a marker of catabolism (P = 0.03). In the nested case-control study, IGFBP-1 was increased after hypoglycemia, whereas the somatotropic axis and the counterregulatory hormones cortisol and glucagon did not change. CONCLUSIONS Despite improved PICU outcome, IIT did not counteract the catabolic state of critical illness. Suppression of portal insulin may have resulted in lower bioavailable IGF-I.

Abstract
To determine whether peer-reviewed consensus statements have changed clinical practice, we surveyed acromegaly care in specialist centers across the globe, and determined the degree of adherence to published consensus guidelines on acromegaly management. Sixty-five acromegaly experts who participated in the 7th Acromegaly Consensus Workshop in March 2009 responded. Results indicated that the most common referring sources for acromegaly patients were other endocrinologists (in 26% of centers), neurosurgeons (25%) and primary care physicians (21%). In sixty-nine percent of patients, biochemical diagnoses were made by evaluating results of a combination of growth hormone (GH) nadir/basal GH and elevated insulin like growth factor-I (IGF-I) levels. In both Europe and the USA, neurosurgery was the treatment of choice for GH-secreting microadenomas and for macroadenomas with compromised visual function. The most widely used criteria for neurosurgical outcome assessment were combined measurements of IGF-I and GH levels after oral glucose tolerance test (OGTT) 3 months after surgery. Ninety-eight percent of respondents stated that primary treatment with somatostatin receptor ligands (SRLs) was indicated at least sometime during the management of acromegaly patients. In nearly all centers (96%), the use of pegvisomant monotherapy was restricted to patients who had failed to achieve biochemical control with SRL therapy. The observation that most centers followed consensus statement recommendations encourages the future utility of these workshops aimed to create uniform management standards for acromegaly.

Abstract
OBJECTIVE The Acromegaly Consensus Group met in April 2009 to revisit the guidelines on criteria for cure as defined in 2000. PARTICIPANTS Participants included 74 neurosurgeons and endocrinologists with extensive experience of treating acromegaly. EVIDENCE/CONSENSUS PROCESS: Relevant assays, biochemical measures, clinical outcomes, and definition of disease control were discussed, based on the available published evidence, and the strength of consensus statements was rated. CONCLUSIONS Criteria to define active acromegaly and disease control were agreed, and several significant changes were made to the 2000 guidelines. Appropriate methods of measuring and achieving disease control were summarized.

Abstract
The V Consensus Group Meeting on 'Guidelines for Treatment of GH Excess and GH Deficiency in the Adult' was an international workshop held on February 20-22, 2006 in Santa Monica, California, USA. The principal aim of this meeting was to provide guidelines for the evaluation and treatment of adults with either form of abnormal GH secretion: GH excess or GH deficiency. The workshop included debates as to the choice of primary treatment, discussions of the targets for adequate treatment, and concluded with presentations on open issues germane to adult GH treatment including the role of GH in malignancies, the impact of longterm treatment on bone, and a cost-benefit analysis. The meeting was comprised of 66 delegates representing 13 different countries.

Abstract
OBJECTIVE Derangements of the GH-IGF-I axis have been associated with microalbuminuria (MA) in type 1 diabetes. The aim of this study was to investigate whether an IGF-I gene promoter polymorphism influenced the development of persistent MA in type 1 diabetes. DESIGN A prospective follow-up study of a cohort of 277 patients with newly diagnosed type 1 diabetes consecutively enrolled between September 1979 and August 1984. METHODS Urinary albumin excretion rate over 24 h was measured in each patient at least once a year. Persistent MA was defined as a urinary albumin excretion rate between 30 and 300 mg/24 h. RESULTS During a median follow-up of 18.0 years (range 1.0-21.5), 79 of 277 patients developed persistent MA. IGF-I gene genotype was available for 216 subjects; in 73% of the subjects, the wild-type genotype of this IGF-I gene polymorphism was present, while 27% had the variant type. At baseline, there were no differences in IGF-I levels and HbA(1c) values between subjects with the wild type and subjects with variant type. By Kaplan-Meier analysis, subjects with the variant type of this polymorphism had during follow-up a higher risk of development of MA compared subjects with the wild type (P = 0.03). CONCLUSIONS Subjects with the variant type of an IGF-I gene polymorphism had a significantly increased risk of developing MA. This risk was not mediated through changes in circulating IGF-I levels. Our study suggests that in type 1 diabetes, this IGF-I gene polymorphism is a risk factor of MA.

Abstract
Fifty-one adrenal pheochromocytomas and 14 paragangliomas were evaluated for somatostatin (SRIH) receptor content with in vitro autoradiography on tissue sections from surgically removed tumors, using iodinated 125I[Tyr]3 octreotide as radioligand. Thirty-seven of 51 pheochromocytomas were SRIH receptor positive (73%), as well as 13 of 14 paragangliomas (93%). These SRIH receptors were of high affinity, pharmacologically specific for SRIH and localized on the tumor tissue. Using in vivo imaging techniques with radiolabeled SRIH analogs, paragangliomas could be visualized in five patients, as well as pheochromocytomas in two of three patients. All tumors tested subsequently in vitro (n = 7) were shown to contain SRIH receptors. A majority of pheochromocytomas were also shown to have a high tumoral SRIH content as measured by immunohistochemical techniques. Detection of SRIH messenger RNA in pheochromocytomas by in situ hybridization indicated that the SRIH was produced in the tumors. A weak inverse correlation was observed between SRIH receptor status and tumoral SRIH content, suggesting that SRIH receptors may be down-regulated by high levels of endogenous SRIH in some tumors. There was no correlation between the SRIH receptor status and sex, age, tumor size, benign vs. malignant tumor, or urinary metanephrine excretion. These tumors were also analyzed for allelic losses on various chromosomes and showed significant loss of heterozygosity (LOH) on chromosomes 1p, 3p, 17p, and 22q. All eight tumors with LOH on chromosome 1p were SRIH receptor positive (100%), whereas only 6 of 11 tumors without LOH on 1p (55%) were SRIH receptor positive, suggesting a correlation between LOH on 1p and SRIH receptor positive status. SRIH receptors thus represent a consistent pathobiochemical marker for most of these adrenal and extra-adrenal tumors. In addition, these receptors may be of potential interest for the in vivo localization of these tumors.

Abstract
We recently described a case of congenital dopamine beta-hydroxylase (DBH) deficiency. The syndrome is characterized by noradrenergic denervation, adrenomedullary failure, but intact baroreflex afferents, cholinergic innervation, and adrenocortical function. Norepinephrine, epinephrine, and their degradation products were undetectable in plasma, urine, and cerebrospinal fluid, whereas dopamine and its degradation products were elevated. Plasma DBH was not detectable. Studies in this novel syndrome showed evidence for the peripheral production of dopamine from sympathetic nerve terminals noradrenergic in nature. Tyrosine hydroxylase is probably induced in this syndrome, since plasma levels of L-DOPA were also elevated. Absence of hemodynamic effects of sympathicolytic agents in the face of an increase in blood pressure after dopamine antagonists suggest that intrasynaptic concentrations of dopamine are in the range of its plasma concentrations. Hypoprolactinemia, reduced REM sleep, increased slow wave sleep and sodium loss, despite low blood pressure, are further evidence for the biological role of dopamine in man.
