Department of Emergency Medicine, The First Affiliated Hospital of Sun Yat-Sen University and Zhongshan Medical School, 26469Sun Yat-Sen University, China.

Neuropathic pain is a common dose-limiting side effect of oxaliplatin, which hampers the effective treatment of tumors. Here, we found that upregulation of transcription factor NFATc2 decreased the expression of Beclin-1, a critical molecule in autophagy, in the spinal dorsal horn, and contributed to neuropathic pain following oxaliplatin treatment. Meanwhile, manipulating autophagy levels by intrathecal injection of rapamycin (RAPA) or 3-methyladenine (3-MA) differentially altered mechanical allodynia in oxaliplatin-treated or naïve rats.

Factors Associated with Infection Severity of Diabetic Foot Ulcers: A Cross-Sectional Study.

Int J Low Extrem Wounds

November 2022

Department of Endocrinology, 56713Sun Yat-sen Memorial Hospital, 26469Sun Yat-sen University, Guangzhou, China.

Article Synopsis
  • Infection in diabetic foot ulcers is a major health issue, leading to hospitalization and amputations, thus highlighting the importance of assessing infection severity using the IDSA/IWGDF classification.
  • A study involving 150 hospitalized diabetic patients identified the prevalence of infection severity as 23.3% mild, 64.7% moderate, and 10.2% severe based on various factors, including Alb levels, CRP, PCT, and microbial type.
  • Results indicated that Alb, CRP, PCT, and the type of bacteria were significantly associated with the severity of infection in diabetic foot ulcers, suggesting potential targets for better management and treatment.

Article Synopsis
  • * The optimal multiplicity of infection (MOI) for the fibroblast-S. aureus co-culture model was found to be 10:1, with various concentrations of CHX-IP yielding differing effects on cell viability over time.
  • * Results indicate that lower concentrations of CHX-IP enhance fibroblast proliferation, while higher concentrations inhibit cell viability, suggesting a concentration-dependent relationship between CHX-IP and fibroblast health in the context of S. aureus infection.

We propose a joint modeling approach to investigate the observed and latent risk factors of the multivariate failure times of interest. The proposed model comprises two parts. The first part is a distribution-free confirmatory factor analysis model that characterizes the latent factors by correlated multiple observed variables.

Current diagnostic methods for colorectal cancer (CRC) are colonoscopy and sigmoidoscopy, which are invasive and complex procedures with possible complications. This study aimed to determine models for CRC identification that involve minimally invasive, affordable, portable, and accurate screening variables. This was a retrospective study that used data from electronic medical records of patients with CRC and healthy individuals between July 2017 and June 2018.

Neuroimaging biomarkers are valuable predictors of motor improvement after stroke, but there is a gap between published evidence and clinical usage. In this work, we aimed to investigate whether machine learning techniques, when applied to a combination of baseline whole brain volumes and clinical data, can accurately predict individual motor outcome after stroke. Upper extremity Fugl-Meyer Assessments (FMA-UE) were conducted 1 week and 12 weeks, and structural MRI was performed 1 week, after onset in 56 patients with subcortical infarction.

Introduction: Sleep apnea/hypopnea syndrome (SAHS) can change brain structure and function. These alterations are related to respiratory event-induced abnormal sleep, however, how brain activity changes during these events is less well understood.

Methods: To study information content and interaction among various cortical regions, we analyzed the variations of permutation entropy (PeEn) and symbolic transfer entropy (STE) of electroencephalography (EEG) activity during respiratory events.

Numerous cases of checkpoint inhibitor-triggered cancer hyperprogression have been documented. A previous hypothesis attributes cancer onset to the local buildup of hydrogen chloride, jointly mediated by hydrogen bond donors and acceptors and basic amino acids. The anti-PD1/PD-L1 immunotherapies may have caused a surge of protons or chloride ions for the effective treatment of neoplasm, thus giving rise to the local formation of hydrogen chloride and subsequently cancer hyperprogression in some susceptible individuals.

A tumorigenic microenvironment can give rise to neoplasm. A shift from this condition to a tumor-suppressive microenvironment is of significant benefit to susceptible individuals. The carbonyl groups of glycine and valine have long bond lengths, consequently generating potent affinities to divalent cations such as calcium.
