Introduction: Primary aldosteronism affects 20% of patients with resistant hypertension and may be due to unilateral or bilateral causes. Patients with a unilateral source of aldosterone secretion are potentially curable with adrenalectomy. Adrenal vein sampling (AVS) is the definitive test for subtype differentiation but may not be accessible outside tertiary centers.

Background: Metastasectomy is a useful adjunct in the management of metastatic cancer. Widespread adoption of novel targeted and immunotherapies has improved the survival profiles of multiple malignancies, which has potentially altered the role of metastasectomy. This study aimed to characterize trends in metastasectomy across five primary cancers eligible for these therapies.

Purpose: Pathogenic germline variants (PGVs) in a subset of cancer predisposition genes (CPGs) are associated with adult-onset autosomal dominant (AD) cancer susceptibility and life-limiting autosomal recessive (AR) disease. Counseling in adult cancer genetics clinics regarding reproductive risk for PGV heterozygotes is limited.

Methods: Estimated heterozygote frequencies across ancestries were calculated for AD CPGs with AR risk (ATM, BRCA1, BRCA2, BRIP1, FH, NBN, MLH1, MSH2, MSH6, PMS2, RAD51C, SDHA, SDHB, and SDHD) from gnomADv.

Article Synopsis
  • Primary aldosteronism is a condition marked by excessive aldosterone production due to adrenal gland lesions, primarily characterized by disrupted regulation of aldosterone synthase (CYP11B2).
  • In a study of aldosterone-producing adenomas (APAs) without known mutations, researchers discovered specific mutations in the gene for mucolipin-3 (TRPML3) associated with increased calcium activity and aldosterone production.
  • These findings suggest that mutations in TRPML3 may contribute to hormone excess in primary aldosteronism, highlighting the disease's underlying genetic factors and their impact on hypertension.

Background: Postoperative hypocalcemia is a common complication of thyroid and parathyroid surgery. Patients with prior gastric bypass face increased risk of postoperative hypocalcemia, but the impact of other malabsorptive conditions is not well understood. In this study, we evaluated the relationship between multiple medical and surgical malabsorptive states and hypocalcemia after thyroid and parathyroid surgery.

Background: Primary aldosteronism (PA) is the most common cause of secondary hypertension, yet screening remains startlingly infrequent. We describe (1) PA screening practices in a large, diverse health system, (2) the development of a computable phenotype for PA screening, and (3) the design and pilot deployment of an electronic health record (EHR)-based active choice nudge to recommend PA screening.

Study Design: A multidisciplinary team developed a multipronged intervention to improve PA screening informed by guidelines, expertise, and multivariable analyses of factors associated with screening.

Article Synopsis
  • Normohormonal primary hyperparathyroidism involves high calcium levels with normal parathyroid hormone, and previous studies indicated that a significant decrease in parathyroid hormone during surgery predicts successful treatment and helps prevent low calcium levels post-surgery.
  • In a study analyzing over 1,000 patients, findings showed similar cure rates between normohormonal (94%) and classic primary hyperparathyroidism (92%), although the average decrease in hormone levels during surgery was lower in normohormonal cases.
  • When applying the earlier established thresholds for hormone reduction, the study confirmed high predictive values for successful treatment and low risk of hypocalcemia for both types of hyperparathyroidism.

Pheochromocytomas and paragangliomas (PPGL) are neuroendocrine tumors which secrete catecholamines, causing cardiovascular compromise. While isolated tumors and locoregional disease can be treated surgically, treatment options for metastatic disease are limited, and no targeted therapies exist. Approximately 25% of PPGL are causatively associated with germline pathogenic variants, which are known risk factors for multifocal and metastatic PPGL.

Pheochromocytomas and paragangliomas are distinctive neuroendocrine tumors which frequently produce excess catecholamines with resultant cardiovascular morbidity. These tumors have a strong genetic component, with up to 40% linked to hereditary pathogenic variants; therefore, germline genetic testing is recommended for all patients. Surgical resection offers the only potential cure in the case of localized disease.

Article Synopsis
  • The study aimed to understand how certain tiny molecules called microRNAs (miRNAs) are connected to a condition called Primary Hyperparathyroidism (PHPT), which affects bones.
  • They looked at women who have PHPT and compared their miRNA levels to women who do not have this condition.
  • The researchers found 9 specific miRNAs that were different in people with PHPT, and these were linked to parathyroid hormone levels, which plays a role in how bones are remodeled, but they did not strongly relate to bone density.

Large tumor size is associated with poorer outcomes in well-differentiated thyroid cancer, yet it remains unclear whether size >4 cm alone confers increased risk, independent of other markers of aggressive disease. The goal of this study was to assess the relationship between tumor size, other high-risk histopathological features, and survival in well-differentiated thyroid cancer and to evaluate the significance of 4 cm as a cutoff for management decisions. Patients with well-differentiated thyroid cancer were identified from the National Cancer Database (2010-2015) and categorized by tumor size (i.

Introduction: The selection of inhaler device is of critical importance in chronic obstructive pulmonary disease (COPD) as the interaction between a patient's inhalation profile and the aerosol characteristics of an inhaler can affect drug delivery and lung deposition. This study assessed the in vitro aerosol characteristics of inhaler devices approved for the treatment of COPD, including a soft mist inhaler (SMI), pressurized metered-dose inhalers (pMDIs), and dry powder inhalers (DPIs).

Methods: High-speed video recording was used to visualize and measure aerosol velocity and spray duration for nine different inhalers (one SMI, three pMDIs, and five DPIs), each containing dual or triple fixed-dose combinations of long-acting muscarinic receptor antagonists and long-acting β-agonists, with or without an inhaled corticosteroid.
