Asymmetric right ventricular myocardial work correlates with gold standard measurements of cardiac function in pulmonary hypertension.

Right ventricular (RV) (dys)function determines outcomes in pulmonary hypertension (PH). We previously found that asymmetric RV myocardial work (MW) corresponds with inefficient RV function in experimental PH models. We therefore aimed to investigate regional distribution of RV MW and its correlation with catheter hemodynamics in children with PH.

Machine learning analysis for detecting late recurrence and loss to follow-up after renal cell carcinoma surgery.

Objectives: Renal cell carcinoma (RCC) is shown to have a tendency for late recurrence, occurring 5 or more years after curative surgery. Imaging diagnosis is required for follow-up, and there is no definitive answer as to how long this should continue. Some patients discontinue follow-up visits at their own discretion.

Risk factors for clinical relapse in patients with ulcerative colitis who are in clinical remission but with endoscopic activity.

Background And Aim: The treatment strategy for patients with ulcerative colitis (UC) in clinical remission who have not achieved mucosal healing is unclear. This study aimed to determine the risk factors of relapse in patients in clinical remission with endoscopic activity.

Methods: This retrospective, single-center study included patients with UC who underwent colonoscopy (CS) and were in clinical remission with endoscopic activity.

Development of the trainer skill evaluation scale for metacognitive training.

Aim: The purpose of this study is manifold: to develop a trainer skill rating scale for metacognitive training (MCT), to determine the difficulty level of the behavioral checklist, and to examine the reliability and validity of the MCT Trainer Skills Rating Scale.

Method: In Study 1, an MCT trainer skill behavior checklist was developed with expert staff members, and a questionnaire was administered to MCT trainers. Item categorization was identical to that used in previous studies.

Gastric metastasis of renal cell carcinoma treated with endoscopic resection: A case report.

Gastric metastasis of renal cell carcinoma (RCC) is rarely encountered. The time interval between the primary diagnosis of RCC and the occurrence of gastric metastasis tends to occur after more than 10 years. Clinicians should be diligent in checking the general symptoms of patients for more than 10 years.

Reliability and validity of a Japanese version of the Brunnsviken Brief Quality of Life Scale.

Aim: The Brunnsviken Brief Quality of Life Scale (BBQ) is a popular quality of life measure, indexing satisfaction with and importance of six empirically selected life domains. Whether these domains hold cross-cultural validity remains largely unexplored. The current study developed and psychometrically validated a Japanese version of the BBQ (BBQ-J).

Association between precautionary behaviors against coronavirus disease and psychosocial factors in outpatients with a pre-existing disease and their attendants.

Aim: The spread of the novel coronavirus infection (coronavirus disease 2019 [COVID-19]) has caused behavioral changes and mental illness in patients and their attendants during its early phase. The present study aimed to examine the association between precautionary behaviors against COVID-19 and psychosocial factors in outpatients with pre-existing disease and their attendants.

Methods: We conducted a cross-sectional paper-based questionnaire survey in Chiba University Hospital on 1019 patients and 513 attendants, and a web-based questionnaire survey in Japan on 3981 individuals from the general population.

Clinical practice for unspecified anxiety disorder in primary care.

Aim: Clinicians face difficulties in making treatment decisions for unspecified anxiety disorder due to the absence of any treatment guidelines. The objective of this study was to investigate how familiar and how often primary care physicians use pharmacological and nonpharmacological approaches to manage the disorder.

Methods: A survey was conducted among 117 primary care physicians in Japan who were asked to assess the familiarity of using each treatment option for unspecified anxiety disorder on a binary response scale (0 = "unfamiliar," 1 = "familiar") and the frequency on a nine-point Likert scale (1 = "never used," 9 = "frequently used").

Saccular abdominal aortic aneurysm in adolescence with tuberous sclerosis.

Key Clinical Message: Abdominal aortic aneurysm complicated by tuberous sclerosis is rare, particularly in patients over the age of 10. It is important to screen for abdominal aortic aneurysm in adolescents diagnosed with tuberous sclerosis regularly.

Abstract: A 15-year-old girl who was diagnosed with tuberculous sclerosis complicated with a saccular aortic abdominal aneurysm (AAA), measuring 19 × 18 mm in diameter.

High intraspecific variability and previous experience affect polyphenol metabolism in polyphagous caterpillars.

Polyphagous insect herbivores feed on multiple host-plant species and face a highly variable chemical landscape. Comparative studies of polyphagous herbivore metabolism across a range of plants is an ideal approach for exploring how intra- and interspecific chemical variation shapes species interactions. We used polyphagous caterpillars of (Erebidae, Lepidoptera) to explore mechanisms that may contribute to its ability to feed on various hosts.

Pneumonia due to with a chronic course resembling non-tuberculous mycobacterial infection.

is a common bacterium that rarely causes pneumonia. Determining whether is the cause of lung infection in patients suspected of having chronic infectious lung disease is challenging because it can present with colonization. We report a case of a 56-year-old immunocompetent woman suspected of having non-tuberculous mycobacteria (NTM) infection on imaging examination and monitored for 3 years.

Penetration of duodenal wall by proximal end of biliary straight plastic stent in a patient with ampullary carcinoma.

A 70-year-old woman presented to our hospital with abdominal discomfort. Gastrointestinal endoscopy revealed an ampullary tumor, while a biopsy revealed a pathological diagnosis of adenocarcinoma. No distant metastases were observed and neoadjuvant chemotherapy and surgical resection were planned.

coinfection with nontuberculous mycobacteria: A case report and literature review.

Six years ago, a 60-year-old man presented to our hospital with a cough and sputum. Upon suspicion of nontuberculous mycobacterial (NTM) infection, he was followed up at our hospital. Because the abnormal shadows in the bilateral lung fields deteriorated slightly over 6 years, bronchoscopy was performed.

Clinical significance of lung cross-sectional area measured by computed tomography in chronic thromboembolic pulmonary hypertension: The correlation with pulmonary hemodynamics and the limitations.

The percentage cross-sectional area of the lung under five (%CSA) is the percentage of pulmonary vessels with <5 mm area relative to the total lung area on computed tomography (CT). The extent that %CSA is related to pulmonary hemodynamics in patients with chronic thromboembolic pulmonary hypertension (CTEPH) is unclear, as is the effect of pulmonary endarterectomy (PEA) on %CSA. Therefore, we aimed to evaluate the clinical significance of %CSA in patients with CTEPH.

Diagnostic imaging of intrathoracic extramedullary haematopoiesis.

Although intrathoracic extramedullary haematopoiesis (EMH) is rare, its nodular lesions should be differentiated from malignancy. In-bone marrow scintigraphy can be useful for the non-invasive diagnosis of intrathoracic EMH because extramedullary accumulation of In can be determined as EMH.

Partially hydrolyzed guar gum suppresses the progression of pulmonary arterial hypertension in a SU5416/hypoxia rat model.

This study investigated the effects of partially hydrolyzed guar gum (PHGG) on the development of pulmonary arterial hypertension using a SU5416/hypoxia rat model. Our results demonstrated that PHGG treatment suppressed the development of pulmonary hypertension and vascular remodeling with an altered gut microbiota composition.

Endoscopic papillary large balloon dilatation-assisted retrieval of a proximally migrated double pigtail stent from the bile duct: A case report.

Double-pigtail stents are commonly used for drainage in cholangitis to prevent stent migration. We report a case in which a double pigtail stent had migrated proximally into the bile duct and was successfully retrieved after endoscopic papillary large balloon dilatation (EPLBD). An 86-year-old man underwent endoscopic papillary sphincterotomy for cholangitis due to common bile duct stones and had a double-pigtail stent placed in the common bile duct.
