Kynurenine pathway (KP) activation is associated with many neuropsychiatric diseases, such as major depressive disorder (MDD) and Alzheimer's disease (AD). Investigations conducted on MDD seldom shed light on KP changes in late-life depression (LLD), though memory deficit (MD) in patients with LLD is a predictable sign of AD. Thus, we aimed to investigate whether tryptophan (TRP) metabolism and kynurenine (KYN) metabolism were imbalanced in patients with LLD with MD and in patients with LLD without MD. We explored KP characteristics between LLD with MD and LLD without MD groups. We investigated 85 patients with LLD and MD, 71 patients with LLD without MD, and 129 healthy controls (HCs). Serum concentrations of TRP, KYN, and kynurenic acid (KYNA) were detected by liquid chromatography-tandem mass spectrometry. Cognition performance was assessed by the Mini-Mental State Examination (MMSE). Language ability was assessed by the Boston Naming Test (BNT). Depressive symptoms were assessed by the 17-item Hamilton Depression Scale (HAMD-17). Lower TRP and KYNA levels, a lower KYNA/KYN ratio and a higher KYN/TRP ratio were found in patients with LLD and MD compared to those in HC. Low levels of TRP and KYN, in the absence of a changed KYN/TRP ratio, were found in patients with LLD without MD. The KYNA/TRP ratio and MMSE, BNT, and HAMD-17 scores were associated with the presence of LLD. MMSE scores and a trend for the KYN/TRP ratio were associated with the presence of MD in patients with LLD. Aside from MMSE scores, there was a trend toward an association between the KYN/TRP ratio and the presence of MD in patients with LLD. In conclusion, profound shifts in TRP metabolism and KYN metabolism were found in patients with LLD and MD but not in patients with LLD without MD.

Introduction: Lower limb length discrepancy (LLD) following hip arthroplasty after proximal femoral fracture (PFFA) is little studied. The aim of this work was to answer the following questions: 1) What are the incidence and mean values of LLD after PFFA? 2) What are the clinical consequences (tolerance) of LLD after PFFA? 3) Can we identify risk factors for LLD after PFFA? 4) Is there a significant difference in terms of LLD after PFFA to treat intra- versus extra-capsular fractures?
Hypothesis: LLD after proximal femoral fracture arthroplasty is rare but has good clinical tolerance, given the low functional demands of the patients.
Patients And Methods: This is a multicenter prospective observational cohort study (15 centers), including 590 patients, operated on for hip arthroplasty for proximal femur fracture between May 2022 and June 2023.

Purpose: To investigate the efficacy of a comprehensive surgical approach for rejuvenation of the aging lower periorbita.
Methods: Between February 2018 and January 2023, 80 eyes of 40 patients with lower lid dermatochalasis (LLD), lower lid laxity (LLL) or orbicularis laxity of the lower lid (OL) admitted to the oculoplastic surgery department of our clinic were included in the study. 18 eyes had LLD, 14 eyes had LLL, 18 eyes had LLD and LLL, and 30 eyes had LLD, LLL and OL.

Lipid-lowering therapy (LLT) includes a diverse group of pharmaceuticals designed to reduce blood levels of cholesterol and triglyceride (TG), helping to prevent cardiovascular diseases like myocardial infarction and stroke. LLT includes treatment with several lipid-lowering drugs (LLD), including hydroxymethylglutaryl (HMG-CoA) reductase inhibitors (statin), PCSK9 Inhibitors, cholesterol-absorbing inhibitors (Ezetimibe), Bile Acid Sequestrants, Fibrates, Niacin (Vitamin B3), Omega-3 Fatty Acids, Bempedoic Acid, and combination therapy. The efficacy and safety of these molecules vary widely.

Background: With the increasing demand for total hip arthroplasty (THA) and the inevitable trend of orthopedic robots and artificial intelligence in the future, it is necessary to explore the safety and effectiveness of orthopedic robots in THA. Currently, most orthopedic robots are in the early stages of development, and evaluating their clinical efficacy can assist in making informed decisions for practical use.
Objective: To explore the advantages of 7 types of robot-assisted THA with respect to 5 indicators.

Aim: To evaluate the medication-related burden (MRB) of patients with late-life depression (LLD) and its influencing factors in China using the Living with Medicines Questionnaire-3 (LMQ-3), providing reference for reducing the MRB of those patients.
Method: A cross-sectional study was conducted between September 2023 and January 2024 on 588 patients with LLD. LMQ-3 and MRB factors questionnaire were used for data collection.
