Anatomical recognition of dissection layers, nerves, vas deferens, and microvessels using artificial intelligence during transabdominal preperitoneal inguinal hernia repair.

Purpose: In laparoscopic inguinal hernia surgery, proper recognition of loose connective tissue, nerves, vas deferens, and microvessels is important to prevent postoperative complications, such as recurrence, pain, sexual dysfunction, and bleeding. EUREKA (Anaut Inc., Tokyo, Japan) is a system that uses artificial intelligence (AI) for anatomical recognition.

MOTS-c modulates skeletal muscle function by directly binding and activating CK2.

MOTS-c is a mitochondrial microprotein that improves metabolism. Here, we demonstrate CK2 is a direct and functional target of MOTS-c. MOTS-c directly binds to CK2 and activates it in cell-free systems.

Dynamic chest radiographic evaluation of the effects of tiotropium/olodaterol combination therapy in chronic obstructive pulmonary disease: the EMBODY study protocol for an open-label, prospective, single-centre, non-controlled, comparative study.

Introduction: To date, there is limited evidence on the effects of bronchodilators on respiratory dynamics in chronic obstructive pulmonary disease (COPD). Dynamic chest radiography (DCR) is a novel radiographic modality that provides real-time, objective and quantifiable kinetic data, including changes in the lung area (Rs), tracheal diameter, diaphragmatic kinetics and pulmonary ventilation during respiration, at a lower radiation dose than that used by fluoroscopic or CT imaging. However, the therapeutic effect of dual bronchodilators on respiratory kinetics, such as chest wall dynamics and respiratory muscle function, has not yet been prospectively evaluated using DCR.

Experience with chemotherapy for postoperative metastases of adenosquamous carcinoma of the esophagogastric junction and pathological study of its development.

Methods: The participants were prospectively recruited from 3 convalescent hospitals.

Artificial intelligence-based model for predicting pulmonary arterial hypertension on chest x-ray images.

Background: Pulmonary arterial hypertension is a serious medical condition. However, the condition is often misdiagnosed or a rather long delay occurs from symptom onset to diagnosis, associated with decreased 5-year survival. In this study, we developed and tested a deep-learning algorithm to detect pulmonary arterial hypertension using chest X-ray (CXR) images.

[A Case of Advanced Esophagogastric Junction Adenocarcinoma with Enlarged Lymph Node Metastases of the Middle Mediastinum and Intraperitoneal That Exhibited pCR by Preoperative SOX Therapy].

A 79-year-old man was diagnosed with esophagogastric junction adenocarcinoma, cT3N3M0, cStage Ⅲ, including enlarged lymph node metastases(Bulky N)in the middle mediastinum and intraperitoneal. A total of 2 cycles of S-1 plus oxaliplatin(SOX)was administered. After neoadjuvant chemotherapy, the primary tumor and enlarged lymph nodes had greatly decreased in size.

Usefulness of central radiologic review in clinical trials of children with hepatoblastoma.

Background: No previous research papers have reported a comparative survey of local radiologic diagnoses and central review in children with hepatoblastoma.

Objective: To evaluate the utility of central review of children with hepatoblastoma enrolled in a clinical trial.

Materials And Methods: The study included 91 children enrolled in a clinical trial conducted by the Japanese Study Group for Pediatric Liver Tumor.

MR Imaging Findings of Carcinoma Ex Pleomorphic Adenoma Related to Extracapsular Invasion and Prognosis.

Background And Purpose: MR imaging can reflect the pathologic progression of carcinoma ex pleomorphic adenoma (CXPA). This study aimed to identify the imaging findings related to extracapsular invasion of CXPA. Additionally, the pathologic background of these findings was investigated.

Genetic polymorphisms in and are associated with serum CK activity after prolonged running in men.

This study aimed to clarify ) the influence of genetic polymorphisms in the cytochrome P450 aromatase gene () on circulating estradiol levels in men and ) whether estrogen-related genetic polymorphisms, such as the rs936306 and estrogen receptor-α () rs2234693 polymorphisms, predict exercise-induced serum creatine kinase (CK) activity, which is an index of skeletal muscle membrane disruption. Serum estradiol levels were examined in young men ( = 167). In a different cohort, serum CK activity was analyzed in a 2-day ultramarathon race: baseline, after the first day, and after the second day (114 males and 25 females).

Modified Socratic Method (planned and executed by Takada) for medical education: Grade II Acute Cholecystitis of Tokyo Guidelines 2018 as an example case.

Background: Socratic method, which is an educational method to promote critical thinking through a dialogue, has never been practiced in a large number of people at the academic societies.

Methods: Modified Socratic method was performed for the first time as an educational seminar using an example case of moderate acute cholecystitis based on the evidence described in Tokyo Guidelines 2018. We adopted a method that Takada had been modifying for many years: the instructor first knows the degree of recognition of the audience, then the instructor gives a lecture in an easy-to-understand manner and receives questions from the audience, followed by repeated questions and answers toward a common recognition.

A case of COVID-19 with the atypical CT finding.

COVID-19 usually demonstrates the specific pattern of chest CT findings (GGO, inverted-halo sign, etc). However, some COVID-19 cases show atypical CT findings. Physicians should make comprehensive judgments.

Paradigm shift regarding the transversalis fascia, preperitoneal space, and Retzius' space.

Background: There has been confusion in the anatomical recognition when performing inguinal hernia operations in Japan. From now on, a paradigm shift from the concept of two-dimensional layer structure to the three-dimensional space recognition is necessary to promote an understanding of anatomy.

Anatomy And Embryology: Along with the formation of the abdominal wall, the extraperitoneal space is formed by the transversalis fascia and preperitoneal space.

Right axillary lymph node metastasis of carcinoma of the cecum with histologically proven cutaneous lymphatic invasion by carcinoma cells: a case report.

Axillary lymph node metastasis from colorectal carcinoma is extremely rare, and this scarcity hinders understanding of its pathogenesis and, thus, the application of appropriate management. Here, we present a case with axillary lymph node metastasis of cecal carcinoma associated with macroscopic invasion of the skin of the abdominal wall with histological evidence of such invasion, findings which support our hypothesis that the axillary lymph node metastasis developed via the lymph channels in the skin of the abdominal wall. A 76-year-old woman with cecal carcinoma (T4N1M0), complicated with an abdominal wall abscess, underwent right hemicolectomy with partial resection of the abdominal wall.

Multiple primary malignancies involving primary sporadic colorectal cancer in Japan: incidence of gastric cancer with colorectal cancer patients may be higher than previously recognized.

Background: Improvement in the prognosis of colorectal cancer (CRC) patients has led to increasing occurrences of multiple primary malignancies (MPMs) alongside CRC but little is known about their characteristics. This study was undertaken to clarify the clinical and pathological features of MPMs, especially those at extra colonic sites, in patients with CRC.

Methods: We reviewed 1,111 patients who underwent operations for primary sporadic CRC in Saitama Medical Center, Jichi Medical University between April 2007 and March 2012.
