ABSTRACT
Crooke cell adenoma (CCA) is a rare and aggressive subtype of a corticotroph adenoma, which requires lifetime surveillance. There have been 106 cases of CCAs reported in the English literature. We describe 2 cases of CCA, a 48-year-old man and an 84-year-old woman who both presented with binocular diplopia and temple pain. Neither case had clinical Cushing syndrome. Laboratory values for the 48-year-old man revealed, adrenocorticotropin (ACTH) 103â pg/mL (22â pmol/L) (RR: 7-63â pg/mL) and evening cortisol 14â µg/dL (386â nmol/L) (RR: 2.7-10.5â µg/dL). Computed tomography imaging demonstrated a mass adjacent to the right cavernous sinus extending into the sphenoid sinus. He underwent tumor resection with adjuvant radiation and has had a stable residual tumor for 4 years. Preoperative laboratory values for the 84-year-old woman revealed, ACTH 69â pg/mL (15 pmol/L) (RR: 7-63â pg/mL) and evening cortisol 16.2â µg/dL (447â nmol/L) (RR: 2.7-10.5 µg/dL). Brain magnetic resonance imaging revealed, a mass compressing the optic chiasm. She underwent resection and has had a stable residual tumor for 2 years. Surgical pathology in both cases revealed cytoplasmic hyaline deposits of more than 50% of the tumor cells, consistent with CCA. The CCA although rare, should be considered when evaluating cases with subclinical Cushing disease and visual symptoms.
ABSTRACT
BACKGROUND: Angiotensin receptor blockers (ARB) and angiotensin-converting enzyme inhibitors (ACEI) increase the expression of ACE2, which is a receptor for entry of SARS-CoV-2 into cells. Though evidence suggests that ARB/ACEI are safe among the general population with COVID-19, their safety in patients with overweight/obesity-related hypertension deserves further evaluation. OBJECTIVE: We assessed the association between ARB/ACEI use and COVID-19 severity in patients with overweight/obesity-related hypertension. METHODS: This study included 439 adult patients with overweight/obesity (body mass index ≥ 25 kg/m2) and hypertension, diagnosed with COVID-19 and admitted to University of Iowa Hospitals and Clinic from March 1 to December 7, 2020. Mortality and severity of COVID-19 were evaluated based on length of stay in hospital, intensive care unit admission, use of supplemental oxygen, mechanical ventilation, and vasopressors. Multivariable logistic regression was used to examine the associations of ARB/ACEI use with mortality and other markers of COVID-19 severity, with a two-sided alpha set at 0.05. RESULTS: Exposure to ARB (n = 91) and ACEI (n = 149) before hospitalization was significantly associated with lower mortality (odds ratio [OR] = 0.362, 95% confidence interval [CI] 0.149 to 0.880, p = 0.025) and a shorter length of stay (95% CI -0.217 to -0.025, p = 0.015). Additionally, patients using ARB/ACEI showed a non-significant trend toward lower intensive care unit admission (OR = 0.727, 95% CI 0.485 to 1.090, p = 0.123), use of supplemental oxygen (OR = 0.929, 95% CI 0.608 to 1.421, p = 0.734), mechanical ventilation (OR = 0.728, 95% CI 0.457 to 1.161, p = 0.182), and vasopressors (OR = 0.677, 95% CI 0.430 to 1.067, p = 0.093). CONCLUSION: Results suggest that hospitalized patients with COVID-19 and overweight/obesity-related hypertension who were prescribed ARB/ACEI before admission to the hospital exhibit lower mortality and less severe COVID-19 than those who were not taking ARB/ACEI. The results also suggest that exposure to ARB/ACEI may protect patients with overweight/obesity-related hypertension from severe COVID-19 and death.
FUNDAMENTO: Os bloqueadores dos receptores da angiotensina (BRA) e os inibidores da enzima conversora da angiotensina (IECA) aumentam a expressão de ACE2, que é um receptor para entrada de SARS-CoV-2 nas células. Embora as evidências sugiram que os IECA/BRA são seguros entre a população geral com COVID-19, sua segurança em pacientes com hipertensão relacionada ao sobrepeso/obesidade merece uma avaliação mais aprofundada. OBJETIVO: Avaliamos a associação entre o uso de IECA/BRA e a gravidade da COVID-19 em pacientes com hipertensão relacionada ao sobrepeso/obesidade. MÉTODOS: O presente estudo incluiu 439 pacientes adultos com sobrepeso/obesidade (índice de massa corporal ≥ 25 kg/m2) e hipertensão, diagnosticados com COVID-19 e internados no University of Iowa Hospitals and Clinic entre 1º de março e 7 de dezembro de 2020. Foram avaliadas a mortalidade e a gravidade da COVID-19 com base no tempo de internação hospitalar, internação em unidade de terapia intensiva, uso de oxigênio suplementar, ventilação mecânica e uso de vasopressores. A regressão logística multivariável foi usada para examinar as associações do uso de IECA/BRA com a mortalidade e outros marcadores de gravidade de COVID-19, com um alfa bilateral definido em 0,05. RESULTADOS: A exposição aos BRA (n = 91) e IECA (n = 149) antes da hospitalização foi significativamente associada a menor mortalidade ( odds ratio [OR] = 0,362, intervalo de confiança [IC] de 95% 0,149 a 0,880, p = 0,025) e menor tempo de internação hospitalar (IC 95% −0,217 a −0,025, p = 0,015). Adicionalmente, os pacientes em uso de IECA/BRA apresentaram uma tendência não significativa de menor internação em unidade de terapia intensiva (OR = 0,727, IC 95% 0,485 a 1,090, p = 0,123), uso de oxigênio suplementar (OR = 0,929, IC 95% 0,608 a 1,421,p = 0,734), ventilação mecânica (OR = 0,728, IC 95% 0,457 a 1,161, p = 0,182) e vasopressores (OR = 0,677, IC 95% 0,430 a 1,067, p = 0,093). CONCLUSÃO: Os resultados sugerem que pacientes internados com COVID-19 e hipertensão relacionada ao sobrepeso/obesidade que receberam IECA/BRA antes da internação apresentam menor mortalidade e COVID-19 menos grave do que aqueles que não estavam tomando IECA/BRA. Os resultados também sugerem que a exposição aos IECA/BRA pode proteger pacientes com hipertensão relacionada ao sobrepeso/obesidade de COVID-19 grave e morte.

Importance: Perception of weight loss requirements before bariatric surgery varies among patients, physicians, and health insurance payers. Current clinical guidelines do not require preoperative weight loss because of a lack of scientific support regarding its benefits. Objective: To examine the association of preoperative body mass index (BMI) and weight loss with 30-day mortality after bariatric surgery. Design, Setting, and Participants: This cohort study used data from 480â¯075 patients who underwent bariatric surgery from 2015 to 2017 in the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program, which covers more than 90% of all bariatric surgery programs in the United States and Canada. Clinical and demographic data were collected at all participating institutions using a standardized protocol. Data analysis was performed from December 2018 to November 2019. Exposures: Preoperative BMI and weight loss. Main Outcomes and Measures: 30-day mortality after bariatric surgery. Results: Of the 480â¯075 patients (mean [SD] age 45.1 [12.0] years; 383â¯265 [79.8%] women), 511 deaths (0.1%) occurred within 30 days of bariatric surgery. Compared with patients with a preoperative BMI of 35.0 to 39.9, the multivariable-adjusted odds ratios for 30-day mortality for patients with preoperative BMI of 40.0 to 44.9, 45.0 to 49.9, 50.0 to 54.9, and 55.0 and greater were 1.37 (95% CI, 1.02-1.83), 2.19 (95% CI, 1.64-2.92), 2.61 (95% CI, 1.90-3.58), and 5.03 (95% CI, 3.78-6.68), respectively (P for trend < .001). Moreover, compared with no preoperative weight loss, the multivariable-adjusted odds ratios for 30-day mortality for patients with weight loss of more than 0% to less than 5.0%, 5.0% to 9.9%, and 10.0% and greater were 0.76 (95% CI, 0.60-0.96), 0.69 (95% CI, 0.53-0.90), and 0.58 (95% CI, 0.41-0.82), respectively (P for trend = .003). Conclusions and Relevance: In this study, even moderate weight loss (ie, >0% to <5%) before bariatric surgery was associated with a lower risk of 30-day mortality. These findings may help inform future updates of clinical guidelines regarding bariatric surgery.

ABSTRACT
Persons with cardiovascular disease (CVD) and diabetes consistently have worse clinical outcomes than those without diabetes. Treatment of diabetes with CVD must target blood pressure, cholesterol, and glycemic targets. Control of blood pressure to pound 130/80 mm Hg and low-density lipoprotein cholesterol to less than 100 mg/dL is key to preventing and managing CVD with diabetes. Optimal glucose control should be a goal in treating diabetes and CVD, in both hospital and outpatient settings. This article focuses on the oral antihyperglycemic agents and insulins available for diabetes pharmacotherapy. Effective glucose management using these agents when interventional procedures and cardiac surgery are to be performed is possible. Practical strategies include combination therapies and use of insulins subcutaneously or by intravenous infusion. Emerging therapies may impact outcomes for diabetes with CVD, including use of insulin sensitizers, drug-eluting stents, and brachytherapy. Attention is currently focused on the insulin sensitizers (metformin and thiazolidinediones), as they appear to impact processes related to the insulin resistance syndrome and the vascular pathophysiologic changes of atherosclerosis. It remains to be seen whether or not the insulin-sensitizing agents will confer a definitive advantage in treating the patient with diabetes for the prevention of or intervention for CVD.
