PURPOSE: Thyroid cancer is the most common malignancy affecting the endocrine glands. The incidence of his malady has conspicuously increased during the recent years. Thyroid diseases affect women approximately 3 times more often than men, and this incidence decreases after menopause. This gender difference has suggested that the female sex steroids stimulate the growth of the thyroid, the same as for the breast. In the present study, we investigated the expressions of estrogen receptor (ER) and progesterone receptor (PR) in thyroid lesions. METHODS: The tissues from 193 human thyroid glands (136 thyroid cancers and 57 adenomatous hyperplasias) were used for the present immunohistochemical assessment of the ER and PR expressions. RESULTS: The incidences of the estrogen and progesterone receptor positive cases were 19.7 and 41.5%, respectively. The incidence of the progesterone receptor positive cases was higher for females (46.5%) than for males (19.4%) however, the expression of estrogen receptor was not different significantly between the females and males. Higher expressions of estrogen and progesterone receptors were detected in the thyroid cancers than in the adenomatous hyperplasias. The PR expression seemed to correlate with the tumor size: a higher PR expression was found in the T3 cancers than in the T2 cancers. CONCLUSION: Our findings provide new insight that the ER and PR expressions may be related to the pathogenesis and progression of thyroid cancer.

Objective:
The development of individual subtypes based on biomarkers offers a cost-effective and timely avenue to comprehending individual differences pertaining to mental health, independent from individuals’ subjective insights. Incorporating 2-channel electroencephalography (EEG) and photoplethysmogram (PPG), we sought to establish a subtype classification system with clinical relevance.
Methods:
One hundred healthy participants and 99 patients with psychiatric disorders were recruited. Classification thresholds were determined using the EEG and PPG data from 2,278 individuals without mental disorders, serving to classify subtypes in our sample of 199 participants. Multivariate analysis of variance was applied to examine psychological distinctions among these subtypes. K-means clustering was employed to verify the classification system.
Results:
The distribution of subtypes differed between healthy participants and those with psychiatric disorders. Cognitive abilities were contingent upon brain subtypes, while mind subtypes exhibited significant differences in symptom severity, overall health, and cognitive stress. K-means clustering revealed that the results of our theory-based classification and data-driven classification are comparable. The synergistic assessment of both brain and mind subtypes was also explored.
Conclusion
Our subtype classification system offers a concise means to access individuals’ mental health. The utilization of EEG and PPG signals for subtype classification offers potential for the future of digital mental healthcare.

Purpose:
The obesity prevention and management program led by public health centers are important in the community.This study aims to identify the current status of obesity prevention and management programs at public health centers and perceptions regarding facilitators and barriers when implementing programs.
Methods:
This study used a concurrent mixed methods design. A survey was conducted to investigate the current status and infrastructure of the obesity prevention and management program at eighty-three public health centers nationwide. Nine program managers and six local residents with experience in the program were interviewed by using a semi-structured questionnaires.
Results
Most of the infrastructure facilities for the program were inadequate, and insufficient budgets and lack of professional staff were identified as barriers. Facilitators included diversification of program delivery methods, operator competence, and visible outcomes and rewards. For the effectiveness of the program, it is vital to have adequate assistants, a sufficient budget, various promotional methods, and connections with various institutions in the community. On this basis, it is acknowledged that the public health center serves as a platform for preventing and managing obesity in the community. Conclusion: It is expected that infrastructure improvements in public health centers and the link with community resources are needed. In addition, there is an urgent need to set standards for obesity prevention and management programs implemented in public health centers to ‘resolve regional disparities’.

PURPOSE: Neoadjuvant chemotherapy (NCT) is a treatment modality that increases the breast-conserving rate in breast cancer. This prospective study was performed to evaluate the actual breast-conserving rate using NCT in a clinical setting in a single institution. METHODS: Between 2014 and 2015, 265 patients who were scheduled to receive NCT and surgery were enrolled in this study. Patients were classified into three groups based on the immunohistochemical results of estrogen receptor (ER)/progesterone receptor (PR) and human epidermal growth factor receptor 2 (HER2): ER or PR positive (luminal), ER/PR negative and HER2 positive (HER2+), and triple-negative breast cancer (TNBC). Before starting and immediately after completing NCT, a surgeon decided if breast-conserving surgery (BCS) or total mastectomy (TM) should be performed. We analyzed the rate of type of surgery performed. RESULTS: Before administering NCT, 107 patients (40.4%) and 158 patients (59.6%) were candidates for BCS and TM, respectively. Of the 158 patients, 61 were eligible for BCS after chemotherapy, with a conversion rate of 38.6%. NCT increased the BCS eligible rate from 40.4% to 62.6%. Of the 61 patients, 53 chose to undergo BCS, and BCS was successful in 46 (86.8%). Of the 107 BCS candidates at baseline, 100 patents finally underwent BCS (93.5%). According to the subtype, the conversion rates were 35.4%, 50.0%, and 40.5% for luminal, HER2+, and TNBC groups, respectively. CONCLUSION: NCT increased the eligibility for BCS from 40.4% to 62.6% in a clinical setting. This benefit is similar to that observed in other clinical trials.
