Background: This study aimed to (1) determine the association between varus knee deformity and ipsilateral foot and ankle morphology, and (2) evaluate the relationship between varus knee deformity and foot and ankle pain in patients with end-stage varus knee osteoarthritis (KOA).

Methods: A total of 213 patients who underwent primary total knee arthroplasty for end-stage varus KOA were enrolled in this study and divided into a 'severe varus group' (n = 119) and a 'mild varus group' (n = 94) based on preoperative knee varus degree. Morphological parameters and pain incidence in the foot and ankle were compared between the two groups.

Article Synopsis
  • Sepsis is a serious condition linked to multiple organ failures, and this study explores a new prognostic model using ferroptosis-related genes (FRGs) to better predict patient outcomes.
  • Researchers identified 27 differentially expressed FRGs and found three distinct molecular subtypes of sepsis that show varying immune responses.
  • The FRG-based prognostic model indicates that patients with a low FRG score have better clinical outcomes, and TFRC is identified as a crucial gene that helps inhibit ferroptosis, suggesting it could be a target for future treatments.

Consensus on the lung cancer management after third-generation EGFR-TKI resistance.

Lancet Reg Health West Pac

December 2024

Guangdong Lung Cancer Institute, Guangdong Provincial People's Hospital (Guangdong Academy of Medical Sciences), Southern Medical University, Guangzhou, China.

Article Synopsis
  • Lung cancer is the most common type of cancer in the Asia-Pacific region, with non-small cell lung cancer (NSCLC) making up about 85% of cases, and a significant mutation rate of 40-60% in Asian patients with lung adenocarcinoma.
  • Third-generation EGFR tyrosine kinase inhibitors (EGFR-TKIs) have improved treatment for NSCLC with mutations, but managing resistance to these drugs is still a major issue with no standardized guidelines.
  • A set of recommendations has been developed, integrating international guidelines and regional clinical experiences, to help healthcare providers classify resistance, conduct clinical testing, and devise treatment strategies for patients struggling with resistance to third-generation EGFR-TKIs.

Periodontitis is a multifactorial disease characterized by chronic destruction of the periodontal supporting tissues and is closely associated with the dysbiosis of the plaque biofilm. It is the leading cause of tooth loss in adults. Bacterial extracellular vesicles (BEVs) are released from bacteria, which range in size from 20 to 400 nm.

Background: Pulmonary embolism (PE) as a preventable and potentially fatal noncommunicable disease was believed to have a lower incidence in Asian populations compared to Western populations. However, the incidence and mortality rates of PE in China and the impact of venous thromboembolism (VTE) prevention system constructions on PE still lack nationwide evidence.

Methods: For this nationwide hospital-based observational study, we used data from the National Hospital Quality Monitoring System (HQMS) and public database in China.

Background & Aims: Current prognostic models for patients with hepatocellular carcinoma (HCC) undergoing transarterial chemoembolization (TACE) are not extensively validated and widely accepted. We aimed to develop and validate a continuous model incorporating tumor burden and biology for individual survival prediction and risk stratification.

Methods: Overall, 4,377 treatment-naive candidates for whom TACE was recommended, from 39 centers in five countries, were enrolled and divided into training, internal validation, and two external validation datasets.

The Wallace H. Coulter Department of Biomedical Engineering, Georgia Institute of Technology and Emory University, Atlanta, Georgia 30332, United States.

As a ubiquitous feature of the biological world, gradation, in either composition or structure, is essential to many functions and processes. Taking protein gradation as an example, it plays a pivotal role in the development and evolution of human bodies, including stimulation and direction of the outgrowth of peripheral nerves in a developing fetus. It is also critically involved in wound healing by attracting and guiding immune cells to the site of injury or infection.

Background: Sorafenib is a first-line treatment for hepatocellular carcinoma (HCC); however, acquired resistance often results in a poor prognosis, indicating a need for more effective therapies. Sorafenib induces cell death through an iron-dependent mechanism known as ferroptosis, which is closely associated with the onset and progression of HCC.

Methods: This study investigated the role of ACSL3 in sorafenib resistance and ferroptosis in HCC.
