Objective: If excellent response (ER) occurs after radioactive iodine (RAI) treatment in patients with differentiated thyroid carcinoma (DTC), the recurrence rate is low. Our study aims to predict ER at 6-24 months after RAI by using machine learning (ML) methods in which clinicopathological parameters are included in patients with DTC without distant metastasis.

Methods: Treatment response of 151 patients with DTC without distant metastasis and who received RAI treatment was determined (ER/nonER). Thyroidectomy ± neck dissection pathology data, laboratory, and imaging findings before and after RAI treatment were introduced to ML models.

Results: After RAI treatment, 118 patients had ER and 33 had nonER. Before RAI treatment, TgAb was positive in 29% of patients with ER and 55% of patients with nonER (p = 0.007). Eight of the ML models predicted ER with high area under the ROC curve (AUC) values (> 0.700). The model with the highest AUC value was extreme gradient boosting (AUC = 0.871), the highest accuracy shown by gradient boosting (81%).

Conclusions: ML models may be used to predict ER in patients with DTC without distant metastasis.

Introduction: Hypertrophic cardiomyopathy (HCM) is a common genetic heart disorder. It is characterized by left ventricular hypertrophy and impaired cardiac function, with forms categorized into obstructive (oHCM) and nonobstructive (nHCM). Traditional treatments address symptoms but not the underlying disease mechanism, highlighting the need for novel therapies.

Thyroid cancer, one of the most common endocrine tumors, generally has a favorable prognosis but remains a significant medical and societal concern due to its high incidence. Early diagnosis and treatment of differentiated thyroid cancer (DTC) significantly affect long-term outcomes, requiring the selection and application of appropriate initial treatments to improve prognosis and quality of life. Recent advances in technology and health information systems have enhanced our understanding of the molecular genetics of thyroid cancer, facilitating the identification of aggressive subgroups and enabling the accumulation of research on risk factors through big data.

Introduction: Papillary thyroid carcinoma (PTC) has an excellent prognosis, but few cases are treatment-resistant. To check the applicability of combined and MEK-targeted therapy, the current study correlated with the MAPK pathway activation status in a cohort of PTCs. The prognostic relevance of and the usability of immunohistochemistry (IHC) for detecting the mutation were also assessed.

Is there a mental health diagnostic crisis in primary care? Current research practices in global mental health cannot answer that question.

In low- and middle-income countries, fewer than 1 in 10 people with mental health conditions are estimated to be accurately diagnosed in primary care. This is despite more than 90 countries providing mental health training for primary healthcare workers in the past two decades. The lack of accurate diagnoses is a major bottleneck to reducing the global mental health treatment gap.

Background And Objective: Bacillus Calmette-Guérin (BCG) reduces disease recurrence and progression in intermediate- and high-risk non-muscle-invasive bladder cancer (NMIBC). BCG-associated adverse events during instillations are common, leading to treatment cessation. Prophylactic use of quinolones in conjunction with BCG instillations is one approach for reducing BCG-associated adverse events.
