Biliary strictures caused by inflammation or fibrosis lead to jaundice and cholangitis which often make it difficult to distinguish malignant strictures. In cases when malignancy cannot be excluded, surgery is often performed. The concept of immunoglobulin G4 (IgG4)-related sclerosing cholangitis (SC) as a benign biliary stricture was recently proposed. The high prevalence of the disease in Asian countries has resulted in multiple diagnostic and treatment guidelines; however, there is need to formulate a standardized diagnostic strategy among various countries considering the utility, invasiveness, and cost-effectiveness. We evaluated accuracies of various diagnostic modalities for biliary strictures comparing pathology in the Delphi meetings which were held in Rochester, MN. The diagnostic utility for each modality was graded according to the experts, including gastroenterologists, endoscopists, radiologists, and pathologists from the United States and Japan. Diagnostic utility of 10 modalities, including serum IgG4 level, noninvasive imaging, endoscopic ultrasound, endoscopic retrograde cholangiopancreatography-related diagnostic procedures were advocated and the reasons were specified. Serum IgG4 level, noninvasive imaging, diagnostic endoscopic ultrasound and intraductal ultrasonography under endoscopic retrograde cholangiopancreatography were recognized as useful modalities for the diagnosis. The information in this article will aid in the diagnosis of biliary strictures particularly for distinguishing IgG4-SC from cholangiocarcinoma and/or primary SC.Therapeutic antibody discovery using synthetic diversity has been proved productive, especially for target proteins not suitable for traditional animal immunization-based antibody discovery approaches. Recently, many lines of evidences suggest that the quality of synthetic diversity design limits the development success of synthetic antibody hits. The aim of our study is to understand the quality limitation and to properly address the challenges with a better design. Using VH3-23 as a model framework, we observed and quantitatively mapped CDR-H3 loop length-dependent usage of human IGHJ4 and IGHJ6 germline genes in the natural human immune repertoire. Skewed usage of DH2-JH6 and DH3-JH6 rearrangements was quantitatively determined in a CDR-H3 length-dependent manner in natural human antibodies with long CDR-H3 loops. Structural modeling suggests choices of JH help to stabilize antibody CDR-H3 loop and JH only partially contributes to the paratope. Our observations shed light on the design of next-generation synthetic diversity with improved probability of success.The study objective was to identify sociodemographic and coronavirus disease 2019 (COVID-19) factors that are associated with COVID-19 vaccine hesitancy among adolescent and young adult (AYA) cancer survivors. Eligible participants were 18 years or older and were diagnosed with cancer as an AYA (ages 15-39 years) and received services through an AYA cancer program. 1,2,3,4,6-O-Pentagalloylglucose A total of 342 participants completed a cross-sectional survey. Our primary outcome-COVID-19 vaccine hesitancy-was surveyed as a 5-point Likert scale and operationalized as a binary outcome (agree vs hesitant). A large proportion of participants reported COVID-19 vaccine hesitancy (37.1%). In the multivariable regression, female survivors (odds ratio = 1.81, 95% confidence interval = 1.10 to 2.98) and survivors with a high school education or less (odds ratio = 3.15, 95% confidence interval = 1.41 to 7.04) reported higher odds of vaccine hesitancy compared with their male or college graduate or higher counterparts. COVID-19 vaccine hesitancy persists among AYA survivors despite their recommended priority vaccination status and higher chances of severe COVID-19 outcomes.

Cushing syndrome (CS) is associated with impaired health-related quality of life (HRQOL) even after surgical cure.

To characterize patient and provider perspectives on recovery from CS, drivers of decreased HRQOL during recovery, and ways to improve HRQOL.

Cross-sectional observational survey.

Patients (n = 341) had undergone surgery for CS and were members of the Cushing's Support and Research Foundation. Physicians (n = 54) were Pituitary Society physician members and academicians who treated patients with CS.

Compared with patients, physicians underestimated the time to complete recovery after surgery (12 months vs 18 months,

 = 0.0104). Time to recovery did not differ by CS etiology, but patients with adrenal etiologies of CS reported a longer duration of cortisol replacement medication compared with patients with Cushing disease (12 months vs 6 months,

 = 0.0025). Physicians overestimated the benefits of work (26.9% vs 65.3%,

 < 0.0001), exercise (40.9% vs 77.6%,

 = 0.0001), and actiduring recovery.

Patients with serotonin-secreting neuroendocrine neoplasms (NENs) have increased serum 5-hydroxyindoleacetic acid (5HIAA) concentrations. Serum 5HIAA thus serves as a biomarker in NEN.

To evaluate an improved tandem mass spectrometric serum 5HIAA assay for diagnosis and follow-up of NEN in a clinical cohort.

A retrospective study during 2016-2018 at the Diagnostic Center and Department of Endocrinology at Helsinki University Hospital, Finland.

Detailed patient data was obtained from 116 patients. Serum 5HIAA was analyzed by 2 different liquid chromatography with tandem mass spectrometry (LC-MS/MS) assays with samples prepared either by protein precipitation or solid phase extraction. Twenty-four-hour urine 5HIAA samples (n = 33) were analyzed by amperometric LC, and the results were compared. Specificity and sensitivity were calculated by receiver operating characteristic (ROC) analysis.

We achieved 5 to10 000 nmol/L linearity and ≤2.5% variation with our new serum 5HIAA assay. In ROC analysis, the area under curve was 85% by serum assays [upper reference limit (URL) value 123 nmol/L] and 88% by the 24-h urine 5HIAA assay (URL value of 47.1 µmol), respectively. A difference (

 < 0.001) between patients with active NEN and patients in remission was found by all 5HIAA assays.

Serum 5HIAA by LC-MS/MS after protein precipitation performs equally well for the diagnosis of NEN as urinary 5HIAA LC assay. The outcome and sensitivity for serum and 24-h urine assays are convergent. Due to much more reliable and convenient sampling, we recommend serum instead of 24-h urine 5HIAA for diagnosis and follow-up of NEN patients.
