Article Synopsis
- This study assesses the outcomes of adrenalectomy for pheochromocytoma in obese versus nonobese patients, using data from 46 centers from 2012 to 2022.
- It finds that while obesity does not significantly increase the rate of complications or comprehensive complication index (CCI), it does lead to a longer hospital stay for patients.
- Furthermore, minimally invasive surgical techniques, like laparoscopic and robotic surgeries, are associated with less morbidity in obese patients, and a retroperitoneal approach may provide additional benefits.
: Mild autonomous cortisol secretion (MACS) can coexist with primary aldosteronism (PA). The purpose of our study was to evaluate whether (MACS) influences parameters analyzed during adrenal venous sampling (AVS) in patients with PA. : Patients with PA from the SPAIN-ALDO Registry and the German Conn's Registry with available 1 mg-dexamethasone suppression test (DST) and AVS were included.

- The study aimed to assess the impact of smoking on the health profile and surgical outcomes of patients with primary aldosteronism (PA).
- In a retrospective analysis of 881 PA patients from 36 Spanish hospitals, smokers exhibited higher rates of left ventricular hypertrophy (LVH) and larger adrenal tumors compared to non-smokers, although their blood pressure and potassium levels were similar at diagnosis.
- The results indicated that while smoking is linked to a greater prevalence of LVH and mild autonomous cortisol secretion (MACS), it does not significantly influence hypertension cure rates after surgery for PA.
Background And Objective: Robotic adrenalectomy (RA) has attracted interest as an alternative to laparoscopic adrenalectomy (LA) for patients with pheochromocytoma, although its beneficial effects are uncertain. Our aim was to compare RA and LA outcomes for these patients.
Methods: Data for patients who underwent RA or LA for pheochromocytoma in 46 international centers between 2012 and 2022 were reviewed.
Aim: To evaluate the impact of aldosterone excess on renal function in individuals with primary aldosteronism and to compare its evolution after surgery or mineralocorticoid receptor antagonist (MRA) treatment.
Methods: A multicentre, retrospective cohort study of primary aldosteronism patients in follow-up in 36 Spanish tertiary hospitals, who underwent specific treatment for primary aldosteronism (MRA or adrenalectomy).
Results: A total of 789 patients with primary aldosteronism were included, with a median age of 57.
Purpose: To evaluate the rate of recurrence among patients with pheochromocytomas and sympathetic paragangliomas (PGLs; together PPGLs) and to identify predictors of recurrence (local recurrence and/or metastatic disease).
Methods: This retrospective multicenter study included information of 303 patients with PPGLs in follow-up in 19 Spanish tertiary hospitals. Recurrent disease was defined by the development of local recurrence and/or metastatic disease after initial complete surgical resection.
Purpose: To identify presurgical and surgical risk factors for intraoperative hypertensive crisis in patients with pheochromocytomas and sympathetic paragangliomas (PGLs) (PPGLs).
Methods: Retrospective multicenter cohort study of patients with PPGLs from 18 tertiary hospitals. Intraoperative hypertensive crisis was defined as systolic blood pressure (SBP) greater than 200 mmHg lasting more than 1 min and postoperative hypertensive crisis as SBP greater than 180 mmHg or diastolic blood pressure (DBP) greater than 110 mmHg.
Purpose: to perform an external validation of our predictive model to rule out pheochromocytoma (PHEO) based on unenhanced CT in a cohort of patients with PHEOs and adenomas who underwent adrenalectomy.
Methods: The predictive model was previously developed in a retrospective cohort of 1131 patients presenting with adrenal lesions. In the present study, we performed an external validation of the model in another cohort of 214 patients with available histopathological results.
Article Synopsis
- This study looked at how common it is for people with a condition called primary aldosteronism (PA) to also have a problem with cortisol production, known as autonomous cortisol secretion (ACS).
- They found that about 29% of patients with PA had ACS, especially those who were older or had larger tumors.
- Despite some differences in age and tumor size, having ACS didn't change how well patients did after surgery or their overall health compared to those who only had PA.
Introduction: It is estimated that 30-40% of patients with apparently sporadic pheochromocytomas (PHEOs) have an inherited predisposition syndrome. The aim of our study was to develop a predictive model of hereditary PHEO based on the clinical, hormonal, and radiological features present at the diagnosis of patients with PHEOs.
Methods: A retrospective multicenter cohort study of patients with PHEOs with available genetic study from 18 tertiary hospitals.
The objective of our study was to determine the prevalence of glycemic disorders (diabetes mellitus and prediabetes) in patients with pheochromocytomas and sympathetic paragangliomas (PPGLs) and identify risk factors for their development and the likelihood of their resolution after surgery. A multicentric retrospective study of patients with PPGLs submitted to surgery between 2000 and 2021 in 17 Spanish hospitals was performed. Diabetes-specific data were collected at diagnosis, in the immediate- and long-term postsurgical follow-up.

Despite the recent identification of brown adipose tissue (BAT) as a potential target in the management of obesity, the use of ASCs isolated from BAT as a therapy for patients with obesity has not yet been explored. Metabolic activation of BAT has been shown to have not only thermogenic effects, but it also triggers the secretion of factors that confer protection against obesity.

Design And Methods: Single centre retrospective study. From 2010 to 2015, 130 patients with adrenal incidentaloma were evaluated and followed-up.
