RESUMO
INTRODUCTION: Advances in endoscopic endonasal transsphenoidal surgery have led to improved post-operative outcomes after pituitary adenoma resection, including reduced length of stay, complications and readmission rates, without compromising safety and satisfaction. METHODS: Our team implemented a perioperative protocol in January 2021 for patients undergoing endoscopic, transsphenoidal pituitary surgery. This study compares pre-operative characteristics and post-operative outcomes in 279 patients between 2016 and 2022 (128 pre-protocol and 151 post-protocol). Our protocol includes interdisciplinary pre-operative evaluations, unified communication, cortisol thresholds for post-operative glucocorticoid replacement, and fluid restriction to prevent delayed hyponatremia. RESULTS: Median age was 54 ± 17 years with 50.8% females. There were 229 (82.1%) macroadenomas (> 1 cm) and 50 (17.9%) microadenomas/cysts (< 1 cm). Mean diameter was 18 (transverse), 18 (cranio-caudal), 16 (antero-posterior) mm. Tumor types included 125 (44.8%) gonadotroph, 46 (16.4%) adrenocorticotroph, 40 (14.3%) lactotroph, 26 (9.3%) Rathke's cysts, 19 (6.8%) somatotroph, 13 (4.6%) non-diagnostic, 3 (1%) somatotroph-lactotroph, 3 (1%) mammosomatotroph, 2 (0.71%) null cell, and 2 (0.7%) thyrotroph adenomas. Post-protocol, 74.2% of patients were discharged on POD1, compared to 46.1% pre-protocol (p<0.0001). Transient arginine vasopressin deficiency (AVD) decreased from 10.4% (pre-protocol) to 4.6% post-protocol (p=0.101). Hyponatremia occurred in 13.3% pre-protocol and 4.6% post-protocol. Emergency department visits dropped from 9.4% to 3.9%, and readmissions decreased from 7.8% to 2.6%. Persistent AVD affected 2.3% pre-protocol and 1.3% post-protocol patients. CSF leaks occurred in 8.5% pre-protocol and 7.3% post-protocol. CONCLUSION: Implementing an interdisciplinary, peri-operative protocol for transsphenoidal endoscopic pituitary surgery improves length of stay while minimizing readmissions and surgery-related complications.
RESUMO
INTRODUCTION: Acromegaly is a rare endocrine disorder usually caused by a benign growth hormoneâsecreting pituitary adenoma. Surgical adenoma resection is typically the first line of treatment, and medical therapy is used for patients with persistent disease following surgery, for adenoma recurrence, or for patients ineligible for, or declining, surgery. Approved somatostatin receptor ligands (SRLs) have been limited to injectable options, until recently. Oral octreotide capsules (OOC) are the first approved oral SRL for patients with acromegaly. AREAS COVERED: We review published reports and provide case study examples demonstrating practical considerations on the use of OOC. Using two hypothetical case scenarios, we discuss current treatment patterns, breakthrough symptoms and quality of life (QoL), efficacy of SRLs, OOC dose titration, evaluation of OOC treatment response, and incidence and management of adverse events. EXPERT OPINION: OOC are an option for patients with acromegaly including those who experience breakthrough symptoms, who have preference for oral therapies, or other reasons for declining injectable SRLs. OOC have been associated with improved patient-reported QoL measures compared with those reported for lanreotide and octreotide. Continued real-world experience will determine whether OOC, alone or in combination with other therapies, provides further advantages over current injectable acromegaly treatments.

Introduction: Pasireotide, a somatostatin receptor ligand, is approved for treating acromegaly and Cushing's disease (CD). Hyperglycemia during treatment can occur because of the drug's mechanism of action, although treatment discontinuation is rarely required. The prospective, randomized, Phase IV SOM230B2219 (NCT02060383) trial was designed to assess optimal management of pasireotide-associated hyperglycemia. Here, we investigated predictive factors for requiring antihyperglycemic medication during pasireotide treatment. Methods: Participants with acromegaly or CD initiated long-acting pasireotide 40 mg/28 days intramuscularly (acromegaly) or pasireotide 600 µg subcutaneously twice daily during pre-randomization (≤16 weeks). Those who did not need antihyperglycemic medication, were managed with metformin, or received insulin from baseline entered an observational arm ending at 16 weeks. Those who required additional/alternative antihyperglycemic medication to metformin were randomized to incretin-based therapy or insulin for an additional 16 weeks. Logistic-regression analyses evaluated quantitative and qualitative factors for requiring antihyperglycemic medication during pre-randomization. Results: Of 190 participants with acromegaly and 59 with CD, 88 and 15, respectively, did not need antihyperglycemic medication; most were aged <40 years (acromegaly 62.5%, CD 86.7%), with baseline glycated hemoglobin (HbA1c) <6.5% (<48 mmol/mol; acromegaly 98.9%, CD 100%) and fasting plasma glucose (FPG) <100 mg/dL (<5.6 mmol/L; acromegaly 76.1%, CD 100%). By logistic regression, increasing baseline HbA1c (odds ratio [OR] 3.6; P=0.0162) and FPG (OR 1.0; P=0.0472) and history of diabetes/pre-diabetes (OR 3.0; P=0.0221) predicted receipt of antihyperglycemic medication in acromegaly participants; increasing baseline HbA1c (OR 12.6; P=0.0276) was also predictive in CD participants. Investigator-reported hyperglycemia-related adverse events were recorded in 47.9% and 54.2% of acromegaly and CD participants, respectively, mainly those with diabetes/pre-diabetes. Conclusion: Increasing age, HbA1c, and FPG and pre-diabetes/diabetes were associated with increased likelihood of requiring antihyperglycemic medication during pasireotide treatment. These risk factors may be used to identify those who need more vigilant monitoring to optimize outcomes during pasireotide treatment.

Invasive prolactinomas often require multimodal management including medical and surgical interventions. Here, we present the case of a 34-year-old man with a history of progressive visual disturbances. MRI unveiled a sella lesion with suprasellar and retrosellar extensions. Elevated prolactin levels (6125 ng/mL) confirmed the diagnosis of prolactinoma, leading to initiation of medical treatment, with gradual escalation to maximum dosing. The patient achieved only partial hormonal response and incomplete improvement of symptoms, and therefore, surgical intervention was pursued with objective of maximum safe resection. The patient consented to the procedure. An endonasal endoscopic approach was selected. Surgical procedures encompassed transsellar, transtuberculum, and transplanum approaches, extended laterally to expose the right parasellar carotid and the anterior wall of the cavernous sinus. Subsequent steps involved opening the sellar and suprasellar dura mater, anterior wall of the cavernous sinus, and transcavernous hemipituitary transposition for access to the retrosellar region.1-5 Debulking of the lesion was performed, followed by dissection of the retrosellar space and resection of tumor component within the interpeduncular cistern. Reconstruction employed dura substitute and vascularized nasoseptal flap. Histopathology confirmed diagnosis of prolactinoma. Postoperative MRI findings and significantly improved prolactin levels (50 ng/mL) were compatible with near total resection. The patient's postoperative course was uneventful, resulting in discharge on the second postoperative day. The patient was additionally started on cabergoline 0.5 mg 2x/week to achieve hormonal control. This case demonstrates the application of surgical anatomy and its translation in modern surgical techniques that allow improved resection of such complex tumors while ensuring optimal clinical outcomes.
RESUMO
BACKGROUND: PIT1 is a pituitary transcription factor that is associated with either growth hormone (GH), prolactin (PRL), or thyroid-stimulating hormone (TSH) production. However, PIT1-positive pituitary neuroendocrine tumors (PitNETs) are occasionally immunonegative for GH, PRL, and TSH. This paper describes the clinical presentation of PIT1 positive however immunonegative PitNETs. METHODS: We conducted a retrospective analysis, identifying 228 PIT1-positive PitNET patients between 2017 and 2022. Out of these, ten (4%) tested negative for GH, PRL, and TSH. Functioning PitNETs were defined as those causing hormonal excess symptoms or hormonal overproduction. RESULTS: As for 10 patients immunonegative for all three hormones however PIT1-positive, the mean ( ± standard deviation) age was 46 ± 13 years with 70% women. Six patients exhibited signs of excess GH or PRL, and three had visual problems. Additionally, one patient had secondary hypothyroidism and adrenal insufficiency resulting from the mass effect. All tumors were macroadenoma, with a median volume of 2.1 cm3 (range, 0.8-17.5 cm3). Gross total resection was attained in six patients by trans-sphenoidal surgery. Postoperatively, eight patients experienced clinical improvement: three in vision, two in amenorrhea, two in headache, and one in acromegaly symptoms. Biochemical improvement was observed in six patients, with all experiencing remission in hormonal excess and one showing improvement in secondary hypothyroidism. Stereotactic radiosurgery was performed in three patients. CONCLUSIONS: Patients with functioning PitNETs may exhibit PIT1 staining without GH, PRL, or TSH staining. Hormonally active tumors exist in this patient population; therefore, close endocrine follow-up is necessary despite the lack of staining for GH, PRL, and TSH.

BACKGROUND: Recruitment for clinical studies is challenging. To overcome barriers, investigators have previously established call-to-entry rates to assist in planning. However, rates specific to low-income minority populations are needed to account for additional barriers to enrolment these individuals face. OBJECTIVE: To obtain a call-to-entry rate in a low-income uninsured Hispanic population with chronic disease. METHODS: We used data from four of our randomised clinical studies to determine the call-to-entry rate for individuals (n=1075) with or at risk for type 2 diabetes: participants needed/potential participants contacted=recruitment rate (yield). Research staff contacted potential participants to enrol in a study that evaluated 6 month diabetes programmes at community clinics from 2015 to 2020. We recorded call-to-entry rates, reasons for declining the study, show rates, and attrition. RESULTS: The call-to-entry rate was 14.5%. Forty per cent of potential participants could not be contacted, and 30.6%, 19.1%, and 5.4% responded yes, no, and maybe, respectively. No show percentages were 54% for yes and 91.4% for maybe responders. The majority (61.6%) declined due to inability to attend; reasons to decline included work (43%), eligibility (18%), transportation (10%), out of town (9%), did not think they needed the programme (7%) and other/unknown (14%). Being a physician predicted inability to reach participants (adjusted OR 2.91, 95% CI 1.73 to 4.90). Attrition was 6.8%. CONCLUSIONS: We described a call-to-entry rate and detailed recruitment data, including reasons to decline the study. This valuable information can assist investigators in study planning and overcoming enrolment barriers in low-income populations. Telehealth-based or strategies that limit transportation needs may increase participant involvement. TRIAL REGISTRATION NUMBER: NCT03394456.

This Consensus Statement from an international, multidisciplinary workshop sponsored by the Pituitary Society offers evidence-based graded consensus recommendations and key summary points for clinical practice on the diagnosis and management of prolactinomas. Epidemiology and pathogenesis, clinical presentation of disordered pituitary hormone secretion, assessment of hyperprolactinaemia and biochemical evaluation, optimal use of imaging strategies and disease-related complications are addressed. In-depth discussions present the latest evidence on treatment of prolactinoma, including efficacy, adverse effects and options for withdrawal of dopamine agonist therapy, as well as indications for surgery, preoperative medical therapy and radiation therapy. Management of prolactinoma in special situations is discussed, including cystic lesions, mixed growth hormone-secreting and prolactin-secreting adenomas and giant and aggressive prolactinomas. Furthermore, considerations for pregnancy and fertility are outlined, as well as management of prolactinomas in children and adolescents, patients with an underlying psychiatric disorder, postmenopausal women, transgender individuals and patients with chronic kidney disease. The workshop concluded that, although treatment resistance is rare, there is a need for additional therapeutic options to address clinical challenges in treating these patients and a need to facilitate international registries to enable risk stratification and optimization of therapeutic strategies.

In recent years, the endoscopic endonasal approach (EEA) for craniopharyngiomas has proven to be a safe option for extensive tumor resection, with minimal or no manipulation of the optic nerves and excellent visualization of the superior hypophyseal branches when compared to the Transcranial Approach (TCA). However, there is an ongoing debate regarding the criteria for selecting different approaches. To explore the current results of EEA and discuss its role in the management of craniopharyngiomas, we performed MEDLINE, Embase, and LILACS searches from 2012 to 2022. Baseline characteristics, the extent of resection, and clinical outcomes were evaluated. Statistical analysis was performed through an X2 and Fisher exact test, and a comparison between quantitative variables through a Kruskal-Wallis and verified with post hoc Bonferroni. The tumor volume was similar in both groups (EEA 11.92 cm3, -TCA 13.23 cm3). The mean follow-up in months was 39.9 for EEA and 43.94 for TCA, p = 0.76). The EEA group presented a higher visual improvement rate (41.96% vs. 25% for TCA, p < 0.0001, OR 7.7). Permanent DI was less frequent with EEA (29.20% vs. 67.40% for TCA, p < 0.0001, OR 0.2). CSF Leaks occurred more frequently with EEA (9.94% vs. 0.70% for TCA, p < 0.0001, OR 15.8). Recurrence rates were lower in the EEA group (EEA 15.50% vs. for TCA 21.20%, p = 0.04, OR 0.7). Our results demonstrate that, in selected cases, EEA for resection of craniopharyngiomas is associated with better results regarding visual preservation and extent of tumor resection. Postoperative CSF leak rates associated with EEA have improved compared to the historical series. The decision-making process should consider each person's characteristics; however, it is noticeable that recent data regarding EEA justify its widespread application as a first-line approach in centers of excellence for skull base surgery.
RESUMO
OBJECTIVE: This 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. METHODS: The 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. RESULTS: This 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. CONCLUSIONS: Aligning 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.

BACKGROUND: The complex nature and heterogeneity involving pituitary surgery results have increased interest in machine learning (ML) applications for prediction of outcomes over the last decade. This study aims to systematically review the characteristics of ML models involving pituitary surgery outcome prediction and assess their reporting quality. METHODS: We searched the PubMed, Scopus, and Web of Knowledge databases for publications on the use of ML to predict pituitary surgery outcomes. We used the Transparent Reporting of a multivariable prediction model for Individual Prognosis Or Diagnosis (TRIPOD) to assess report quality. Our search strategy was based on the terms "artificial intelligence", "machine learning", and "pituitary". RESULTS: 20 studies were included in this review. The principal models reported in each article were post-surgical endocrine outcomes (n = 10), tumor management (n = 3), and intra- and postoperative complications (n = 7). Overall, the included studies adhered to a median of 65% (IQR = 60-72%) of TRIPOD criteria, ranging from 43% to 83%. The median reported AUC was 0.84 (IQR = 0.80-0.91). The most popular algorithms were support vector machine (n = 5) and random forest (n = 5). Only two studies reported external validation and adherence to any reporting guideline. Calibration methods were not reported in 15 studies. No model achieved the phase of actual clinical applicability. CONCLUSION: Applications of ML in the prediction of pituitary outcomes are still nascent, as evidenced by the lack of any model validated for clinical practice. Although studies have demonstrated promising results, greater transparency in model development and reporting is needed to enable their use in clinical practice. Further adherence to reporting guidelines can help increase AI's real-world utility and improve clinical practice.
RESUMO
Introduction: Nearly half of the adult population in the United States has been diagnosed with hypertension. Adrenal hormonal hypersecretion is a leading cause of secondary hypertension. Adrenal vein sampling (AVS) may assist in differentiating between unilateral and bilateral adrenal hormonal hypersecretion to identify patients who are candidates for adrenalectomy. We reviewed the use of AVS at our institution along with associated outcomes after adrenalectomy. Materials and Methods: A retrospective chart review was conducted of patients with a diagnosis of primary hyperaldosteronism (PA) or adrenocorticotropic hormone-independent Cushing syndrome (AICS) and who underwent adrenalectomy between January 1, 2010, and December 1, 2021. Patient data of baseline characteristics, preoperative workup, including AVS, and postoperative outcomes were collected and analyzed. Results: Seventy-one patients were identified in the study period (48 PA and 23 AICS). Computed tomography scan identified unilateral adrenal nodules in 52 patients (29 left; and 23 right), bilateral nodules in 13 patients, and no nodules in 6 patients. AVS was performed in 45 patients with PA (93%) and 5 patients with AICS (21%). After surgery, the number of PA patients with hypokalemia or requiring potassium supplementation significantly decreased after adrenalectomy (before surgery: 33 [68.7%]; and after surgery: 5 [10.4%], P < .01). The number of medications required for hypertension in AICS patients also significantly decreased. No major adverse events were noted. Conclusions: Our long-term experience demonstrates the ongoing use of AVS during workup of patients with primary hyperaldosteronism and for select patients with adrenocorticotropic hormone-independent Cushing syndrome. However, a low level of discordance between imaging and AVS findings in PA patients suggests that there may be a subset of patients in whom preoperative AVS is not necessary.

Introduction. Pituitary adenomas have the potential to infiltrate the dura mater, skull, and the venous sinuses. Tumor extension into the cavernous sinus is often observed in pituitary adenomas and techniques and results of surgery in this region are vastly discussed in the literature. Infiltration of parasellar dura and its impact for pituitary surgery outcomes is significantly less studied but recent studies have suggested a role of endoscopic resection of the medial wall of the cavernous sinus, in selected cases. In this study, we discuss the techniques and outcomes of recently proposed techniques for selective resection of the medial wall of the cavernous sinus in endoscopic pituitary surgery. Methods. We performed a systematic review of the literature using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and protocol and a total of 4 studies with 106 patients that underwent an endoscopic approach for resection of pituitary tumors with resection of medial wall from cavernous sinus were included. Clinical and radiological data were extracted (sex, mean age, Knosp, prior surgery, tumor size and type, complication rate, and remission) and a meta-analysis using the RevMan 5.4 software was performed. Results. A total of 5 studies with 208 patients were included in this analysis. The mean age of the study population was 48.87 years (range 25−82) with a female/male ratio of 1:1.36. Majority of the patients had Knosp Grade 1 (n = 77, 37.02%) and Grade 2 (n = 53, 25.48%). The complication rate was 4.81% (n = 33/106) and the most common complication observed was a new transient CN dysfunction and diplopia. Early disease remission was observed in 94.69% of the patients (n = 196/207). The prevalence rate of CS medial wall invasion varied from 10.4 % up to 36.7%. This invasion rate increased in frequency with higher Knosp Grade. The forest plot of persistent disease vs. remission in this surgery approach showed a p < 0.00001 and heterogeneity (I^2 = 0%). Discussion. Techniques to achieve resection of the medial wall of the cavernous sinus via the endoscopic endonasal approach include the "anterior to posterior" technique (opening of the anterior wall of the cavernous sinus) and the "medial to lateral" technique (opening of the inferior intercavernous sinus and). Although potentially related with improved endocrinological outcomes, these are advanced surgical techniques and require extensive anatomical knowledge and extensive surgical experience. Furthermore, to avoid procedure complications, extensive study of the patient's configuration of cavernous ICA, Doppler-guided intraoperative imaging, surgical navigation system, and blunt tip knives to dissect the ICA's plane are recommended. Conclusion. Endoscopic resection of the medial wall of the cavernous sinus has been associated with reports of high rates of postoperative hormonal control in functioning pituitary adenomas. However, it represents a more complex approach and requires advanced experience in endoscopic skull base surgery. Additional studies addressing case selection and studies evaluating long term results of this technique are still necessary.
RESUMO
OBJECTIVE: Clinical paradigms and consensus recommend dopamine agonists (DAs) as the primary treatment for prolactinomas. However, medically treated patients also encounter challenges such as DA resistance, intolerable side effects, and recurrence of hyperprolactinemia after DA withdrawal. Technical advances in transsphenoidal resection, with an endoscopic endonasal approach, have led to improved visualization of tumor, decreased postoperative morbidity, and shortened length of stay. We examined the indications and outcomes in patients with prolactinomas who underwent surgical resection at our center. METHODS: A retrospective analysis was performed of 60 consecutive patients with prolactinomas who underwent endoscopic endonasal transsphenoidal resection between August 2010 and July 2019 and were followed by the same multidisciplinary team. RESULTS: Women comprised 73% of surgical cases, and 60% of the tumors were macroadenomas. The most common primary surgical indication was patient preference (26.6%) followed by DA intolerance (25%) and DA failure (18.3% inadequate shrinkage, 15% persistent hyperprolactinemia, 11.7% both). Gross total resection was noted in 83% and length of stay was 1 day in 92% of patients. Early remission (postoperative day 1 normalization of prolactin off DA therapy) was seen in 71% of all patients, 91% of microadenomas, 56% of macroadenomas, 65% of Knosp grade 0-2 macroadenomas, and 75% of macroadenomas operated on with expectation of a cure. Only 3 patients had recurrence, at 4.3, 3.3, and 1.6 years of follow-up, respectively. CONCLUSIONS: Endoscopic endonasal resection is a viable option for management of patients with prolactinomas in the setting of a high-volume pituitary center, with minimal postoperative complications.

Objective: The objective of this study is to report results from the open-label extension (OLE) of the OPTIMAL trial of oral octreotide capsules (OOC) in adults with acromegaly, evaluating the long-term durability of therapeutic response. Design: The study design is an OLE of a double-blind placebo-controlled (DPC) trial. Methods: Patients completing the 36-week DPC period on the study drug (OOC or placebo) or meeting predefined withdrawal criteria were eligible for OLE enrollment at 60 mg/day OOC dose, with the option to titrate to 40 or 80 mg/day. The OLE is ongoing; week 48 results are reported. Results: Forty patients were enrolled in the OLE, 20 each having received OOC or placebo, with 14 and 5 patients completing the DPC period as responders, respectively. Ninety percent of patients completing the DPC period on OOC and 70% of those completing on placebo completed 48 weeks of the OLE. Maintenance of response in the OLE (i.e. insulin-like growth factor I (IGF1) ≤ 1.0 × upper limit of normal (ULN)) was achieved by 92.6% of patients who responded to OOC during the DPC period. Mean IGF1 levels were maintained between the end of the DPC period (0.91 × ULN; 95% CI: 0.784, 1.045) and week 48 of the OLE (0.90 × ULN; 95% CI: 0.750, 1.044) for those completing the DPC period on OOC. OOC safety was consistent with previous findings, with no increased adverse events (AEs) associated with the higher dose and improved gastrointestinal tolerability observed over time. Conclusions: Patients with acromegaly maintained long-term biochemical response while receiving OOC, with no new AEs observed with prolonged OOC exposure.

OBJECTIVE: The objective of this clinical practice guideline is to provide updated and new evidence-based recommendations for the comprehensive care of persons with diabetes mellitus to clinicians, diabetes-care teams, other health care professionals and stakeholders, and individuals with diabetes and their caregivers. METHODS: The American Association of Clinical Endocrinology selected a task force of medical experts and staff who updated and assessed clinical questions and recommendations from the prior 2015 version of this guideline and conducted literature searches for relevant scientific papers published from January 1, 2015, through May 15, 2022. Selected studies from results of literature searches composed the evidence base to update 2015 recommendations as well as to develop new recommendations based on review of clinical evidence, current practice, expertise, and consensus, according to established American Association of Clinical Endocrinology protocol for guideline development. RESULTS: This guideline includes 170 updated and new evidence-based clinical practice recommendations for the comprehensive care of persons with diabetes. Recommendations are divided into four sections: (1) screening, diagnosis, glycemic targets, and glycemic monitoring; (2) comorbidities and complications, including obesity and management with lifestyle, nutrition, and bariatric surgery, hypertension, dyslipidemia, retinopathy, neuropathy, diabetic kidney disease, and cardiovascular disease; (3) management of prediabetes, type 2 diabetes with antihyperglycemic pharmacotherapy and glycemic targets, type 1 diabetes with insulin therapy, hypoglycemia, hospitalized persons, and women with diabetes in pregnancy; (4) education and new topics regarding diabetes and infertility, nutritional supplements, secondary diabetes, social determinants of health, and virtual care, as well as updated recommendations on cancer risk, nonpharmacologic components of pediatric care plans, depression, education and team approach, occupational risk, role of sleep medicine, and vaccinations in persons with diabetes. CONCLUSIONS: This updated clinical practice guideline provides evidence-based recommendations to assist with person-centered, team-based clinical decision-making to improve the care of persons with diabetes mellitus.

PURPOSE: Transsphenoidal surgery (TSS) is the first-line treatment for patients with Cushing's Disease (CD). Recurrence rates after a first TSS range between 3 and 22% within 3 years. Management of recurrent or persistent CD may include repeat TSS or stereotactic radiosurgery (SRS). We performed a meta-analysis to explore the overall efficacy of TSS and SRS for patients with CD after an initial surgical intervention. METHODS: EMBASE, PubMed, SCOPUS, and Cochrane databases were searched from their dates-of-inception up to December 2021. Inclusion criteria were comprised of patients with an established diagnosis of CD who presented with persistent or biochemically recurrent disease after a first TSS for tumor resection and were treated with a second TSS or SRS. RESULTS: Search criteria yielded 2,116 studies of which 37 articles from 15 countries were included for analysis. Mean age ranged between 29.9 and 47.9 years, and mean follow-up was 11-104 months. TSS was used in 669 (67.7%) patients, while SRS was used in 320 (32.4%) patients, and remission rates for CD were 59% (95%CI 0.49-0.68) and 74% (95%CI 0.54-0.88), respectively. There was no statistically significant difference in the remission rate between TSS and SRS (P = 0.15). The remission rate of patients with recurrent CD undergoing TSS was 53% (95%CI 0.32-0.73), and for persistent CD was 41% (95%CI 0.28-0.56) (P = 0.36). CONCLUSION: Both TSS and SRS are possible approaches for the treatment of recurrent or persistent CD after a first TSS. Our data show that either TSS or SRS represent viable treatment options to achieve remission for this subset of patients.

OBJECTIVE: Acromegaly is characterized by chronic growth hormone (GH) and insulin-like growth factor 1 (IGF-1) hypersecretion, often caused by a GH-secreting pituitary adenoma. Even though surgery remains the first line of treatment, medical therapy is essential if surgery is contraindicated, does not achieve remission, or does not prevent recurrence despite apparent surgical remission. Oral octreotide capsules (OOCs) that combine octreotide with a transient permeability enhancer technology are the first oral somatostatin receptor ligands (SRLs) approved in the United States for acromegaly. METHODS: We review the literature and clinical trial data on OOC therapy in patients with acromegaly and discuss the clinical assessment of OOC use, potential drug-drug interactions, drug initiation, dose titration, and monitoring of drug efficacy and tolerability. RESULTS: In 4 pivotal clinical trials involving 238 patients with acromegaly treated with OOC, effective suppression of serum GH and IGF-1 levels, maintenance of disease control, decreased breakthrough symptoms and symptomatic improvement with non-inferiority of OOCs to injectable SRLs in maintaining biochemical response was seen. Additionally, the safety profile of OOC therapy is comparable to that of injectable SRLs. Most patients who completed the clinical trials of OOCs have also expressed preference for oral compared with injectable SRL administration. CONCLUSION: OOCs are an effective treatment option for patients with acromegaly who previously responded to injectable SRLs, with the benefits of avoiding injection-related side effects. This article provides a review of the pharmacology, safety, and efficacy and offers practical recommendations on the use of OOCs to treat injectable SRL-responsive patients with acromegaly.

OBJECTIVE: The aim of this case-based clinical review was to provide a practical approach for clinicians regarding the management of patients with immune checkpoint inhibitor (ICI)-mediated endocrinopathies. METHODS: A literature search of PubMed, Embase, and Scopus was conducted using appropriate keywords. The discussions and strategies for the diagnosis and management of ICI-mediated endocrinopathies are based on evidence available from prospective, randomized clinical studies; cohort studies; cross-sectional studies; case-based studies; and an expert consensus. RESULTS: Immunotherapy with ICIs has transformed the treatment landscape of diverse types of cancers but frequently results in immune-mediated endocrinopathies that can cause acute and persistent morbidity and, rarely, death. The patterns of endocrinopathies differ between the inhibitors of the cytotoxic T-lymphocyte antigen 4 and programmed cell death protein 1 or programmed cell death protein 1 ligand pathways but most often involve the thyroid and pituitary glands. The less common but important presentations include insulin-deficient diabetes mellitus, primary adrenal insufficiency, primary hypoparathyroidism, central diabetes insipidus, primary hypogonadism, and pancreatitis, with or without subsequent progression to diabetes mellitus or exocrine insufficiency. CONCLUSION: In recent years, with increasing numbers of patients with cancer being treated with ICIs, more clinicians in a variety of specialties have been called upon to diagnose and treat ICI-mediated endocrinopathies. Herein, we reviewed case scenarios of various clinical manifestations and emphasized the need for a high index of clinical suspicion by all clinicians caring for these patients, including endocrinologists, oncologists, primary care providers, and emergency department physicians. We also provided diagnostic and therapeutic approaches for ICI-induced endocrinopathies and proposed that patients on ICI therapy be evaluated and treated by a multidisciplinary team in collaboration with endocrinologists.
