The Breast Cancer Clinical Practice Guidelines, organized by the Japanese Breast Cancer Society (JBCS), were published in 2022. We present the English version of the Radiation Therapy (RT) section of the guidelines. The JBCS formed a task force to update the 2018 version of the JBCS Clinical Practice Guidelines. The Background Questions (BQs) contain the standard treatments for breast cancer in clinical practice, whereas the Clinical Questions (CQs) address daily clinical questions that remain controversial. Future Research Questions (FRQs) explore the subjects that are considered important issues, despite there being insufficient data for inclusion as CQs. The task force selected the 12 BQs, 8 CQs, and 6 FRQs for the RT section. For each CQ, systematic literature reviews and meta-analyses were conducted according to the Minds Manual for Guideline Development 2020, version 3.0. The recommendations, strength of recommendation, and strength of evidence for each CQ were determined based on systematic reviews and meta-analyses, and finalized by voting at the recommendation decision meeting.

The 2022 revision of the Japanese Breast Cancer Society (JBCS) Clinical Practice Guidelines for surgical treatment of breast cancer was updated following a systematic review of the literature using the Medical Information Network Distribution Service (MINDS) procedure, which focuses on the balance of benefits and harms for various clinical questions (CQs). Experts in surgery designated by the JBCS addressed five areas: breast surgery, axillary surgery, breast reconstruction, surgical treatment for recurrent and metastatic breast cancer, and other related topics. The revision of the guidelines encompassed 4 CQs, 7 background questions (BQs), and 14 future research questions (FRQs). A significant revision in the 2022 edition pertained to axillary management after neoadjuvant chemotherapy in CQ2. The primary aim of the 2022 JBCS Clinical Practice Guidelines is to provide evidence-based recommendations to empower patients and healthcare professionals in making informed decisions regarding surgical treatment for breast cancer.

Chronic obstructive pulmonary disease (COPD) is characterized by airflow obstruction on spirometry and symptoms such as dyspnea on exertion and chronic cough with sputum production, thus making it a significant healthcare issue worldwide. Japanese patients with COPD have unique characteristics compared to patients in Western countries, including older age and lower exacerbation frequency. The Japanese Respiratory Society (JRS) published the 6th edition of the COPD guideline in June 2022. This article introduces the management goals of COPD and describes its management during the stable phase, as outlined in the guideline. Management goals include improving the current status, such as the symptoms, quality of life (QOL), exercise tolerance, and physical activity, and reducing future risks through prevention of exacerbation and suppression of disease progression to prevent shortening of healthy life expectancy. Management plans should include avoidance of causative substances, assessment of disease severity, and personalized treatment plans. Pharmacotherapy using inhalation bronchodilators is a key component of the treatment of stable COPD. Bronchodilators, including short- and long-acting dilators, are commonly used to relieve symptoms and improve QOL. Inhaled corticosteroids (ICSs) are used in combination with long-acting bronchodilators, especially in patients with asthma and COPD overlap, or those experiencing frequent exacerbation of eosinophilia. Combination therapy with a long-acting muscarinic antagonist (LAMA), a long-acting beta 2 agonist (LABA), and ICS is expected to improve QOL and respiratory function and reduce mortality and exacerbation compared to the LAMA + LABA combination. Non-pharmacological therapies, including smoking cessation and pulmonary rehabilitation, should also be considered.

The aim of the \"Japanese Clinical Practice Guidelines for Head and Neck Cancer - 2022 Update\" is to review the latest evidence regarding head and neck cancer and to present the current standard approaches for diagnosis and treatment. These evidence-based recommendations were created with the consensus of the Guideline Committee, which is composed of otorhinolaryngologists and head and neck surgeons, together with radiologists, radiation oncologists, medical oncologists, plastic surgeons, dentists, palliative care physicians, and rehabilitation physicians. These guidelines were created by the Clinical Practice Guideline Committee of the Japan Society for Head and Neck Cancer based on the \"Head and Neck Cancer Treatment Guidelines 2018 Edition,\" and the revised draft was compiled after evaluation by the Assessment Committee and public comments. The \'Clinical questions and recommendations\' section consists of 13 categories, and 59 clinical questions are described in total. Here we describe 6 clinical questions specific to other sets of guidelines with recommendations and comments.

Background: To assess the impact of different clinical questions on radiation doses acquired during cardiac computed tomography in children. Methods: A total of 116 children who underwent cardiac CT on a third-generation dual-source CT scanner were included. The clinical questions were divided into three main categories: the extent of scanning in the z-axis, coronary artery assessment and cardiac function assessment. Radiation dose values represented as a dose-length product (DLP) in mGy*cm were recorded from the CT scanner protocols. Results: There were significantly higher doses in cases with cardiac function assessment (median DLP 348 versus 59 mGy*cm, p < 0.01) and in cases with coronary artery assessment (median DLP 133 versus 71 mGy*cm, p < 0.01). Conclusion: The most important factor was the assessment of cardiac function, where the median radiation dose was 4.3× higher in patients with a request for cardiac function assessment. We strongly recommend that clinical requests for cardiac CT should be carefully considered in the paediatric population.

OBJECTIVE: To select and define the clinical questions and outcomes of Guideline for the Emergency Treatment of Anaphylaxis.
METHODS: A draft including clinical questions, which could be divided into foreground questions and background questions, and outcomes was drawn and revised by the secretary group for the guideline referring to the present guidelines with the guidance of a panel consisting of 7 experienced clinical medicine, pharmacy and nursing experts. Foreground questions and outcomes of the draft were voted into a final version after three rounds of counsels of 22 experienced medicine, pharmacy and nursing clinical experts using Delphi method including 3 rounds of inquiry. And the background questions were directly included in the guideline after the 22 experts\' thorough revising. The research was carried out under the supervision of method ologists. Active coefficient, coefficient of variation and the frequencies of each score were calculated for quality control.
RESULTS: The draft of 34 foreground questions, 6 background questions and 6 outcomes was finally drawn up after thorough selecting and consulting. The 6 background questions revised by the clinical experts were all included. After three rounds of Delphi method, 28 pivotal clinical questions covering the diagnosis, preparation for the treatment, treatment and administration after the treatment, and 6 outcomes were defined and included for the guideline. The rest of the foreground questions, 4 of which were recognized as essential and 2 as important, were excluded from the guideline and left for further revising or updating. As for the outcomes, 4 of them were recognized as critical and the rest as important. The experts contributing to the research were active as the active coefficient reached 100%, and the degree of consensus was fine as the frequencies of the feedback scoring equal to or greater than 4 for all the 28 foreground questions included were greater than 75% and the result was settled in the first round. And 2 outcomes, fatality rate and severity, reached a higher degree of consensus with coefficient of variation less than 15%.
CONCLUSIONS: After thorough and rigorous selecting, the clinical questions and outcomes to be included in the Guideline for the Emergency Treatment of Anaphylaxis were finally selected and defined via Delphi method, guiding the future development of the guidelines.

Pre-clerkship clinical skills courses at many medical schools use objective structured clinical examinations (OSCEs) to assess students\' development as it relates to the foundational clinical skills of history taking, communication, and physical examination. The authors report on a curriculum in which OSCEs also serve as a springboard for additional learning by linking them to activities that include patient write-ups, oral presentations, clinical reasoning discussions, clinical question generation, and video review with faculty. The rationale for using OSCEs as an assessment for learning tool is discussed, and some lessons learned are reported.

We have prepared the Japanese Breast Cancer Society clinical practice guidelines (CPGs) for surgical treatment of breast cancer, 2018 update after a systematic review (SR) of the literature based upon the Medical Information Network Distribution Service (Minds) procedure. The CPG committee for surgical treatment of breast cancer, composed of breast surgeons and plastic surgeons treating breast cancer, has developed the CPGs. Eight clinical questions (CQs) were selected and divided roughly into the following five categories: (1) breast surgery in initial therapy (CQs 1-3); (2) axillary surgery in initial therapy (CQs 4-5); (3) breast reconstruction in initial therapy (CQ 6); (4) surgical treatment for recurrent and metastatic breast cancer (CQs 7-8); and (5) others. Recommendations for these CQs were decided by the GRADE grid method. In addition, 4 outlines, 14 background questions (BQs), and 12 future research questions (FQs) were also selected. Statements for these BQs and FQs are provided. We developed the updated CPGs for surgical treatment of breast cancer, 2018, which include 8 CQs and recommendations. As a decision-making tool for the understanding and treatment of breast cancer, these guidelines will help surgical oncologists dealing with breast cancer, medical staff, and patients, along with their family members.
