Social Skills and Reciprocal Behavior with a Virtual Player Among Children With and Without SLD/ADHD.

The study aimed to compare reciprocal behavior during interaction with a virtual-player in a computer game between children with typical development (TD) and children with specific-learning-disabilities (SLD) and/or with attention-deficit/hyperactivity disorder (ADHD), and to examine its correlation with social skills. A total of 120 children (43 SLD/ADHD, 77 TD) aged 9-11 years participated. Participants completed self-reported questionnaires focusing on social skills and reciprocity and played a computer game in which such social situations arose. Results indicated no difference between the groups in self-reported social skills or reciprocity. However, the children's actual reciprocal behavior during gameplay revealed different results: the SLD/ADHD group exhibited higher levels of selfish (helping others for personal gain) and lower levels of altruistic reciprocity (helping others for their benefit) compared to the TD group. Furthermore, a correlation was found between self-reported social skills and reciprocity, as well as with the reciprocal-patterns observed in the gameplay.

The Significance of RAS-Like Mutations and MicroRNA Profiling in Predicting Malignancy in Thyroid Biopsy Specimens.

In cytologically indeterminate thyroid nodules undergoing molecular testing, estimated risk of malignancy is variable. Identification of a non-cancer-specific mutation (RAS-like) confirms a neoplastic process but does not differentiate between benign, malignant, and low-risk neoplasms. This study aims to retrospectively evaluate institutional experience of Interpace (ThyGeNEXT® and ThyraMIR®; Pittsburgh, PA) testing and to determine the rate of malignancy in resected nodules, stratified by mutational analysis and microRNA profile. Of 1917 fine need aspirations, 140 (7.3%) underwent Interpace testing: 47 (33.6%) were molecular-not-benign (harbored mutation, fusion, and/or positive miRNA) and 93 (66.4%) were molecular-benign (no mutations or fusions and negative microRNA). Surgery was spared in 79.6% of molecular-benign and 61.4% of all tested patients. Fifty-four (38.6%) underwent resection. Seventeen (89.5%) of the resected molecular-benign were benign and 2 were malignant. Thirteen (37.1%) of the resected molecular-not-benign were benign, 7 (20%) were noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP), and 15 (42.9%) were malignant (p < 0.05, negative predictive value (NPV) 89.4-95.6%, positive predictive value (PPV) 22.3-42.8%). Most molecular-not-benign (72.3%) had RAS-like mutation. Twenty-three were resected: 3 were malignant and 7 were NIFTP. Nodules with non-RAS-like mutations (BRAF V600E-like, others) were more likely to be malignant than RAS-like (H/N/KRAS, BRAF K601E) (p < 0.05, NPV 86.9-96.5%, PPV 100%). Most nodules had RAS-like mutations and most were benign or low-risk neoplasms (NIFTP). This study supports the role of histologic examination in the distinction of malignancy in RAS-like thyroid neoplasms and underscores the role of molecular testing in risk stratification, patient counseling, and operative management.

A machine-learning algorithm for distinguishing malignant from benign indeterminate thyroid nodules using ultrasound radiomic features.

Background: Ultrasound (US)-guided fine needle aspiration (FNA) cytology is the gold standard for the evaluation of thyroid nodules. However, up to 30% of FNA results are indeterminate, requiring further testing. In this study, we present a machine-learning analysis of indeterminate thyroid nodules on ultrasound with the aim to improve cancer diagnosis. Methods: Ultrasound images were collected from two institutions and labeled according to their FNA (F) and surgical pathology (S) diagnoses [malignant (M), benign (B), and indeterminate (I)]. Subgroup breakdown (FS) included: 90 BB, 83 IB, 70 MM, and 59 IM thyroid nodules. Margins of thyroid nodules were manually annotated, and computerized radiomic texture analysis was conducted within tumor contours. Initial investigation was conducted using five-fold cross-validation paradigm with a two-class Bayesian artificial neural networks classifier, including stepwise feature selection. Testing was conducted on an independent set and compared with a commercial molecular testing platform. Performance was evaluated using receiver operating characteristic analysis in the task of distinguishing between malignant and benign nodules. Results: About 1052 ultrasound images from 302 thyroid nodules were used for radiomic feature extraction and analysis. On the training/validation set comprising 263 nodules, five-fold cross-validation yielded area under curves (AUCs) of 0.75 [Standard Error (SE) = 0.04; P < 0.001 ] and 0.67 (SE = 0.05; P = 0.0012 ) for the classification tasks of MM versus BB, and IM versus IB, respectively. On an independent test set of 19 IM/IB cases, the algorithm for distinguishing indeterminate nodules yielded an AUC value of 0.88 (SE = 0.09; P < 0.001 ), which was higher than the AUC of a commercially available molecular testing platform (AUC = 0.81, SE = 0.11; P < 0.005 ). Conclusion: Machine learning of computer-extracted texture features on gray-scale ultrasound images showed promising results classifying indeterminate thyroid nodules according to their surgical pathology.

A Survey of American Thyroid Association Members Regarding the 2015 Adult Thyroid Nodule and Differentiated Thyroid Cancer Clinical Practice Guidelines.

Background: The 2015 American Thyroid Association (ATA) clinical practice guidelines (CPGs) on management of thyroid nodules (TNs) and differentiated thyroid cancer (DTC) in adults were developed to inform clinicians, patients, researchers, and health policy makers about the best available evidence, and its limitations, relating to management of these conditions. Methods: We conducted a cross-sectional electronic survey of ATA members' perspectives of these CPGs, using a standardized survey (Clinician Guidelines Determinant Questionnaire) developed by the Guidelines International Network. A survey link was electronically mailed to members in February of 2019, with reminders sent to nonrespondents 2 and 5 weeks later. Data were descriptively summarized, after excluding missing responses. Results: The overall response rate was 19.8% (348/1761). The effective response rate was 20.2% (348/1720), after excluding a recently deceased member and individuals who had either invalid e-mail addresses or whose e-mails were returned. Of the respondents, 37.9% (132/348) were female, 60.4% (209/346) were endocrinologists, 27.5% (95/346) were surgeons, and 3.5% (12/346) were nuclear medicine specialists. The majority of respondents (71.9%; 250/348) were at a mid- or advanced-career level, and more than half were in academia (57.5%; 195/339). The majority (69.8%; 243/348) practiced in North America. The vast majority of respondents indicated that the CPGs explained the underlying evidence (92.3%; 298/323) and 92.9% (300/323) agreed or strongly agreed with the content. Most respondents stated that they regularly used the CPGs in their practice (83.0%; 268/323). Most respondents (83.0%; 268/323) also agreed or strongly agreed that the recommendations were easy to incorporate in their practice. The most popular CPG format was an electronic desktop file (78.8%; 252/320). Shorter more frequent CPGs were favored by 55.0% (176/320) of respondents, and longer traditional CPGs were favored by 39.7% (127/320). Conclusions: The clinical content and evidence explanations in the adult TN and DTC CPGs are widely accepted and applied among ATA survey respondents. Future ATA CPG updates need to be optimized to best meet users' preferences regarding format, frequency, and length.

Synchronous and Metastatic Papillary and Follicular Thyroid Carcinomas with Unique Molecular Signatures.

Despite the relatively high prevalence of thyroid cancer, the occurrence of multiple synchronous, distinct subtypes of primary thyroid carcinoma is uncommon. The incidental finding of papillary thyroid microcarcinoma in a gland with a biologically relevant follicular or medullary carcinoma is more frequent than the synchronous occurrence of multiple clinically significant carcinomas. We report a case of synchronous papillary and follicular thyroid carcinomas metastatic to lymph node and bone, respectively. Next generation sequencing showed BRAF V600E mutation in the primary papillary carcinoma and NRAS Q61R mutation in the primary follicular carcinoma and bony metastasis. To our knowledge, this is the first reported case of synchronous and metastatic primary papillary and follicular carcinomas, and the first report of synchronous BRAF V600E mutated papillary and NRAS mutated follicular carcinoma.

Computerized physician order entry of medications and clinical decision support can improve problem list documentation compliance.

OBJECTIVE: The problem list is a key and required element of the electronic medical record (EMR). Problem lists may contribute substantially to patient safety and quality of care. Physician documentation of the problem list is often lower than desired. Methods are needed to improve accuracy and completeness of the problem list. DESIGN: An automated clinical decision support (CDS) intervention was designed utilizing a commercially available EMR with computerized physician order entry (CPOE) and CDS. The system was based on alerts delivered during inpatient medication CPOE that prompted clinicians to add a diagnosis to the problem list. Each alert was studied for a 2-month period after implementation. MEASUREMENTS: Measures included alert validity, alert yield, and accuracy of problem list additions. RESULTS: At a 450 bed teaching hospital, the number of medication orders which triggered alerts during all 2-month study periods was 1011. For all the alerts, the likelihood of a valid alert (an alert that occurred in patients with one of the predefined diagnoses) was 96+/-1%. The alert yield, defined as occuring when an alert led to addition of a problem to the problem list, was 76+/-2%. Accurate problem list additions, defined as additions of problems when the problem was determined to be present by expert review, was 95+/-1%. CONCLUSION: The CDS problem list mechanism was integrated into the process of medication order placement and promoted relatively accurate addition of problems to the EMR problem list.

Clinical presentation and response to therapy in patients with massive prolactin hypersecretion.

Prolactin hypersecretion from a pituitary adenoma usually results in a serum prolactin level less than 1,000 ng/ml. During therapy with a dopamine agonist, prolactin levels usually normalize and the tumors shrink substantially. In the past few years, we have seen three men who presented with serum prolactin levels greater than 10,000 ng/ml. All presented with large tumors, visual field deficits, and hypogonadotropic hypogonadism. All other pituitary hormones were normal. In all three patients, significant tumor shrinkage was achieved with improvement or resolution of headaches and visual field deficits. None of our patients has been able to achieve a normal prolactin or testosterone. A literature review identified 32 patients with prolactin levels of more than 10,000 ng/ml. Twenty-six (81%) were males. Most had large tumors, headaches and visual field defects. Even with the addition of surgery and/or radiation therapy to medical therapy, normalization of serum prolactin occurred in only six patients (19%) and only one man achieved a normal testosterone. We conclude that in patients with massive prolactin hypersecretion, therapy with a dopamine agonist will lead to tumor shrinkage and improvement of mass effects, but usually does not normalize prolactin or testosterone. Rather than waiting for maximal prolactin reduction, we would recommend early institution of testosterone replacement therapy.

Long-term risks for thyroid cancer and other neoplasms after exposure to radiation.

Radiation-related thyroid cancer continues to be a clinical concern for two reasons: the risks associated with the widespread use of radiation treatments for benign conditions in the middle of the last century persist for decades after exposure; and radiation continues to be an effective component of the treatment of several childhood malignancies. Patients who were irradiated in the head and neck area need to be evaluated for thyroid cancer, benign thyroid nodules, hyperparathyroidism, salivary-gland neoplasms and neural tumors, including acoustic neuromas. Radiation-related thyroid cancers appear to have the same clinical behavior as other thyroid cancers, but many irradiated patients are entering the age range when more aggressive neoplasms occur. In this paper, we review how to approach the clinical management of a patient with a history of radiation exposure in the thyroid area, and how to treat radiation-exposed patients who develop related neoplasms, especially thyroid cancer.
