Integrating VAI-Assisted Quantified CXRs and Multimodal Data to Assess the Risk of Mortality.

To address the unmet need for a widely available examination for mortality prediction, this study developed a foundation visual artificial intelligence (VAI) to enhance mortality risk stratification using chest X-rays (CXRs). The VAI employed deep learning to extract CXR features and a Cox proportional hazard model to generate a hazard score ("CXR-risk"). We retrospectively collected CXRs from patients visited outpatient department and physical examination center.

Efficacy of a Novel Intra-Articular Administration of Platelet-Rich Plasma One-Week Prior to Hyaluronic Acid versus Platelet-Rich Plasma Alone in Knee Osteoarthritis: A Prospective, Randomized, Double-Blind, Controlled Trial.

Recent studies have suggested that the combined injection of platelet-rich plasma (PRP) and hyaluronic acid (HA) may have additive benefits for knee osteoarthritis over PRP alone, but there is insufficient evidence to support this combined injection. Moreover, the simultaneous injection of PRP and HA may offset the combined effect. Hence, the aim of this prospective, randomized, double-blind study was to assess their combined efficacy with a novel injection protocol.

The role of the ground-glass opacity ratio in resected lung adenocarcinoma.

Objectives: The goal of this study was to investigate the role of the ground-glass opacity (GGO) ratio in lung adenocarcinoma in predicting surgical outcomes.

Methods: Patients who underwent surgical resection for pulmonary adenocarcinoma between January 2004 and December 2013 were reviewed. The clinical data, imaging characteristics of nodules, surgical approaches and outcomes were analysed with a mean follow-up of 87 months.

Effects of Platelet-Rich Plasma on Pain and Muscle Strength in Patients With Knee Osteoarthritis.

Objective: No studies comparing the effects of platelet-rich plasma (PRP) injection and placebo injection in bilateral knee osteoarthritis in the same patient, or discussing muscle strength after PRP injection, have been published.

Design: Twenty patients with bilateral knee osteoarthritis were eligible, and 40 knees were randomized into two groups: PRP (knees [right or left by a coin toss] receiving a single intra-articular PRP injection) and saline group (the contralateral knee of the same patient, into which single 4-mL intra-articular injection of normal saline was administered). The primary outcome measure was Western Ontario and McMaster's Universities Osteoarthritis Index and the secondary included isokinetic test results.

Pulmonary metastatic gastric cancer mimicking a giant mediastinal cyst.

Cysts and cavities are common radiologic abnormalities. Pulmonary metastasis comprises a rare entity of thoracic cystic diseases. We reported a case of giant cyst at the left anterior mediastinum that was pathologically confirmed as a lung metastasis from previously resected gastric cancer.

Treatment of empyema and bronchopleural fistula by bovine pericardium and latissimus flap.

Management of empyema with bronchopleural fistula remains a challenge. A 38-year-old man who had bullous emphysema was hospitalized on account of a right-sided necrotizing pneumonia complicated by empyema that mandated a tube drainage. Persistent air leak from the chest tube was noted, and chest computed tomography confirmed an empyema cavity with a suspicious bronchopleural fistula.

Subcutaneous abscess in the lower leg caused by BCG-related osteomyelitis.

We report an unusual case of tibial osteomyelitis resulting from Bacille Calmette-Guerin vaccination and causing subsequent cortical destruction and a subcutaneous abscess. A 10-month-old infant initially presented with a tender palpable mass below the left knee. Radiographs showed an osteolytic lesion in the proximal metaphysis of the tibia.
