Following the general check-up and the creation of a study model, the planned implant location demonstrated an external right maxilla diameter of more than 5 mm, thereby validating the cone-beam computed tomography (CBCT) radiograph.

Country-specific key lifestyle factors and health outcomes for resource allocation in the general population: a network analysis across 29 countries.

Background: We aimed to identify the central lifestyle, the most impactful among lifestyle factor clusters; the central health outcome, the most impactful among health outcome clusters; and the bridge lifestyle, the most strongly connected to health outcome clusters, across 29 countries to optimise resource allocation for local holistic health improvements.

Methods: From July 2020 to August 2021, we surveyed 16 461 adults across 29 countries who self-reported changes in 18 lifestyle factors and 13 health outcomes due to the pandemic. Three networks were generated by network analysis for each country: lifestyle, health outcome, and bridge networks.

Late Ultra-High-Risk Recurrence of Gestational Trophoblastic Neoplasia Seven Years Posttreatment.

Gestational trophoblastic neoplasia (GTN) comprises a category of malignant or potentially malignant tumors that arise from gestational trophoblasts. Almost all cases of GTN experience a recurrence within the first year following treatment, although recurrences become rare after five years. Recurrent GTN tends to have a poor prognosis, primarily due to challenges in management, a high rate of relapse, and a low five-year survival rate.

Transcatheter Bailout: An Important Option During Complex Aortic Surgery.

This report presents the case of a 66-year-old man with acute torrential aortic insufficiency after a Ross procedure 20 years earlier, a biologic aortic valve replacement 16 years earlier, and a transcatheter valve-in-valve 4 years earlier. He underwent third-time sternotomy, revealing that the pulmonary autograft was heavily calcified and frozen to the homograft. The previous transcatheter valve-in-valve was explanted.

Cavoatrial Bypass for Cardiac Complications From Rosai-Dorfman Disease.

Hemi-Nikaidoh: Partial Aortic Root Translocation and Posterior Left Ventricular Outflow Tract Plasty.

Among repairs for ventriculoarterial discordance, ventricular septal defect, and pulmonary stenosis, aortic root translocation (Nikaidoh operation) offers the most anatomic result. With a diminutive pulmonary annulus or hypoplastic left ventricular outflow tract, the distance gained posteriorly with aortic translocation is negligible. We developed the "hemi-Nikaidoh" procedure as an alternative.

Exploring the effects of gut microbiota on cholangiocarcinoma progression by patient-derived organoids.

Background: Recent research indicates a role of gut microbiota in development and progression of life-threatening diseases such as cancer. Carcinomas of the biliary ducts, the so-called cholangiocarcinomas, are known for their aggressive tumor biology, implying poor prognosis of affected patients. An impact of the gut microbiota on cholangiocarcinoma development and progression is plausible due to the enterohepatic circulation and is therefore the subject of scientific debate, however evidence is still lacking.

DNA Aptamer-Polymer Conjugates for Selective Targeting of Integrin α4β1 T-Lineage Cancers.

Selective therapeutic targeting of T-cell malignancies is difficult due to the shared lineage between healthy and malignant T cells. Current front-line chemotherapy for these cancers is largely nonspecific, resulting in frequent cases of relapsed/refractory disease. The development of targeting approaches for effectively treating T-cell leukemia and lymphoma thus remains a critical goal for the oncology field.
