From the point of view of medical device registration technical evaluation, production process of endoscope, three-dimensional imaging(3D), high resolution imaging are discussed. We focus on the process of design and development, especially verification and validation. The general principle is that all risks and unexpected impacts should be minimized and acceptable to ensure that benefits are greater than risks in normal use.

Aim: To implement and evaluate an Advanced Practice Nurse-led transitional care model (AdvantAGE) to reduce rehospitalisation rates in frail older adults discharged from a Swiss geriatric hospital.

Design: The study adopts an effectiveness-implementation hybrid design (Type 1) to simultaneously evaluate the effectiveness of the care model and explore the implementation process.

Methods: The primary outcome, the 90-day rehospitalisation rate, will be evaluated using a matched-cohort design with a prospective intervention group and a retrospective control group.

Background: To correlate between immunohistochemical expression of tumor-infiltrating lymphocytes (TILs), tumor-associated macrophages (TAMs), and natural killer (NK) cells with the AJCC 8th edition TNM staging system and other disease-modifying clinico-pathological variables.

Methods: The representative histology sections of tumor invasive margin (IM) and tumor core (TC) were selected according to the International Immuno-Oncology Biomarker Working Group and were subjected to immunohistochemistry with antibodies for TILs (CD3, CD8, FOXP3), NK Cells (CD57), TAMs (CD68, CD163) and pan-leukocyte marker (CD45). Histo-immuno-density-intensity (HIDI) scoring was calculated as a product of the proportion and intensity of staining.

Long-Term Clinical Outcomes and Risk Indicator Analyses of Narrow-Diameter Implants in the Posterior Jaw: A Retrospective Cohort Study of 10 to 27 Years.

Clin Oral Implants Res

January 2025

State Key Laboratory of Oral & Maxillofacial Reconstruction and Regeneration, Key Laboratory of Oral Biomedicine Ministry of Education, Hubei Key Laboratory of Stomatology, School & Hospital of Stomatology, Wuhan University, Wuhan, China.

Objectives: To assess the long-term clinical outcomes and patient satisfaction with narrow-diameter implants (NDIs) in the posterior jaws and to identify the risk indicators for NDI failure.

Materials And Methods: This retrospective study reviewed 479 patients with 666 NDIs (diameter ≤ 3.5 mm) -supported fixed prostheses in posterior jaws, with a minimum 10-year follow-up.

Introduction: Effects of Dapagliflozin (Dapa) and Dapagliflozin-Saxagliptin combination (Combo) was examined on peripheral blood derived CD34 + Hematopoetic Stem Cells (HSCs) as a cellular CVD biomarker. Both Dapa (a sodium-glucose co-transporter 2 or SGLT2, receptor inhibitor) and Saxagliptin (a Di-peptydl-peptidase-4 or DPP4 enzyme inhibitor) are commonly used type 2 diabetes mellitus or T2DM medications, however the benefit of using the combination has not been evaluated for cardio-renal risk assessment, in a real-life practice setting, compared to a placebo.

Hypothesis: We hypothesized that Dapa will improve the outcomes when compared to placebo and the Combo maybe even more beneficial.

Background: A 12-month cluster randomized controlled trial (RCT) demonstrated the effectiveness of an application-based education program in reducing the salt intake and systolic blood pressure (SBP) of schoolchildren's adult family members. This study aimed to assess whether the effect at 12 months persisted at 24 months.

Methods: Fifty-four schools were randomly assigned to either the intervention or control group.
