Identification of High-Risk Patients With Nonalcoholic Fatty Liver Disease Using Noninvasive Tests From Primary Care and Endocrinology Real-World Practices.

INTRODUCTION: We aimed to identify high-risk nonalcoholic fatty liver disease (NAFLD) patients seen at the primary care and endocrinology practices and link them to gastrohepatology care. METHODS: Using the electronic health record, patients who either had the diagnosis of type 2 diabetes or had 2 of 3 other metabolic risk factors met criteria for inclusion in the study. Using noninvasive fibrosis tests (NITs) to identify high risk of fibrosis, patients who met the NIT prespecified criteria were referred to gastrohepatology for clinical assessment and transient elastography. RESULTS: From 7,555 patients initially screened, 1707 (22.6%) met the inclusion criteria, 716 (42%) agreed to enroll, and 184 (25.7%) met the prespecified NIT criteria and eligibility for linkage to GE-HEP where 103 patients (68 ± 9 years of age, 50% men, 56% white) agreed to undergo linkage assessments. Their NIT scores were APRI of 0.38 ± 0.24, FIB-4 of 1.98 ± 0.87, and NAFLD Fibrosis Score of 0.36 ± 1.03; 68 (66%) linked patients had controlled attenuation parameter >248 dB/m, 62 (60%) had liver stiffness <6 kPa, and 8 (8%) had liver stiffness >12 kPa. Liver stiffness for the overall group was 6.7 ± 4.2 kPa, controlled attenuation parameter 282 ± 64 dB/m, and FAST score 0.22 ± 0.22. Linked patients with presumed advanced fibrosis had significantly higher body mass index (36.4 ± 6.6 vs 31.2 ± 6.4 kg/m2, P = 0.025) and higher NIT scores (APRI 0.89 ± 0.52 vs 0.33 ± 0.14, FIB-4 3.21 ± 2.06 vs 1.88 ± 0.60, and NAFLD Fibrosis Score 1.58 ± 1.33 vs 0.25 ± 0.94). DISCUSSION: By applying a simple prespecified multistep algorithm using electronic health record with clinical risk factors and NITs followed by transient elastography, patients with nonalcoholic fatty liver disease seen in PCP and ENDO practices can be easily identified.

Utility of PET/neck MRI digital fusion images in the management of recurrent or persistent thyroid cancer.

BACKGROUND: Approximately 30% of thyroid cancer patients present with reappearing disease within 40 years of initial diagnosis. Hence, sensitive postsurgical monitoring techniques are imperative to successful long-term care. The objective of this study was to assess the added clinical utility of a combined positron emission tomography/magnetic resonance imaging (PET/MRI) of the neck in conjunction with standard imaging in the detection of recurrent thyroid carcinoma. We define standard imaging as a neck sonogram, 131I scan, computed tomography, and MRI. METHODS: This study included 34 patients treated for thyroid cancer at Washington Hospital Center. All patients had previously undergone near-total or total thyroidectomy, standard follow-up imaging studies, and laboratory studies. Twenty-nine of thirty-four patients had received at least one 131I treatment prior to the study. Each patient received a PET and MRI scan, and these images were subsequently digitally fused. RESULTS: Individually and blinded, four endocrinologists retrospectively reviewed all information in patient charts prior to PET and PET/MRI coregistration. A clinical assessment and treatment plan were devised with these data. Following the initial assessment, the endocrinologists were provided results from the PET and PET/MRI fusion studies and asked to make a revised assessment and treatment plan. For each patient, the physicians categorized PET/MRI fusion results as providing new information that altered the initial treatment plan, providing new information that confirmed the initial treatment plan, or providing no additional information. On average, PET/MRI coregistration provided additional information that altered the treatment plan in 46% of the cases, provided additional information that confirmed the treatment plan in 36% of cases, and did not provide any additional information in 18% of cases. CONCLUSION: The combination of structural and functional data that PET/neck MRI fusion offers provided further information in an overwhelming majority of thyroid cancer patients in this study. Thus PET/MRI can be a useful tool in surgical planning, radioactive iodine therapy decisions, and determining the level of follow-up necessary for each patient.

Hypothyroidism.

Hypothyroidism is one of the most common disorders encountered in an endocrine office practice. This article reviews the epidemiology, etiology, clinical presentation, diagnosis, and treatment of hypothyroidism. We emphasize some of the more recent issues, such as combination thyroid hormone therapy, management of hypothyroidism during pregnancy, and the management of subclinical hypothyroidism.
