A Study of N-Acetyl aspartic acid/Creatine Ratio in the White Matter of HIV Positive Patients and Its Application [PDF]

arXiv, 2015
A total of 50 patients were enrolled in the study, and MRI brain with MR spectroscopy was done. Tuberculosis was the most common neurologic disease found in the HIV positive group, consisting of 9 patients. Seven of these patients had tuberculous meningitis amongst which a further 2 had vasculitic infarcts.PML was seen in 6 patients.

Combined spatially resolved metabolomics and spatial transcriptomics reveal the mechanism of RACK1‐mediated fatty acid synthesis

Molecular Oncology, EarlyView.
The authors analyzed the spatial distributions of gene and metabolite profiles in cervical cancer through spatial transcriptomic and spatially resolved metabolomic techniques. Pivotal genes and metabolites within these cases were then identified and validated.

Patient positioning during digital rectal examination of the prostate: preferences, tolerability, and results

International Brazilian Journal of Urology, 2011
PURPOSE: To evaluate the preferred position used by Brazilian Urologists to perform DRE, the position that Brazilian patients prefer or think it is less embarrassing to have a DRE, and to evaluate the results of DRE with patients in left lateral ...

Soft-NeuroAdapt: A 3-DOF Neuro-Adaptive Patient Pose Correction System For Frameless and Maskless Cancer Radiotherapy [PDF]

arXiv, 2017
Precise patient positioning is fundamental to successful removal of malignant tumors during treatment of head and neck cancers. Errors in patient positioning have been known to damage critical organs and cause complications. To better address issues of patient positioning and motion, we introduce a 3-DOF neuro-adaptive soft-robot, called Soft ...

Circulating tumor DNA (ctDNA) trajectories predict survival in trifluridine/tipiracil‐treated metastatic colorectal cancer patients

Molecular Oncology, EarlyView.
The authors applied joint/mixed models that predict mortality of trifluridine/tipiracil‐treated metastatic colorectal cancer patients based on circulating tumor DNA (ctDNA) trajectories. Patients at high risk of death could be spared aggressive therapy with the prospect of a higher quality of life in their remaining lifetime, whereas patients with a ...

Risk factors and characteristics of intraoperative pressure injuries caused by medical devices and adhesives: A case-control retrospective study

Saudi Journal of Anaesthesia
Background: Undesirable injuries during the intraoperative period, such as pressure injuries caused by improper positioning, medical devices, or adhesive tapes, can lead to patient harm and decreased satisfaction.

Crosstalk between gut microbiota and tumor: tumors could cause gut dysbiosis and metabolic imbalance

Molecular Oncology, EarlyView.
In this research, we analyzed the relationship between gut microbiota and tumor. We discovered that both subcutaneous and metastatic tumors would alter the composition and metabolic function of gut microbiota. Meanwhile, fecal microbiota transplantation also indicated the anti‐tumor role of the gut microbiota, revealing the crosstalk between tumor and ...

Equilibrium Behaviors in Repeated Games [PDF]

arXiv, 2020
We examine a patient player's behavior when he can build reputations in front of a sequence of myopic opponents. With positive probability, the patient player is a commitment type who plays his Stackelberg action in every period. We characterize the patient player's action frequencies in equilibrium.

The accumulation of myeloid‐derived suppressor cells participates in abdominal infection‐induced tumor progression through the PD‐L1/PD‐1 axis

Molecular Oncology, EarlyView.
This study explores how sepsis affects GC progression by creating an immunosuppressive environment. Our findings reveal that sepsis promotes immune dysregulation, enhancing tumor growth and metastasis. Targeting the PD‐1/PD‐L1 pathway with monoclonal antibodies shows potential for restoring immune function and improving outcomes in cancer patients ...

A Patient-Centric Dataset of Images and Metadata for Identifying Melanomas Using Clinical Context [PDF]

arXiv, 2020
Prior skin image datasets have not addressed patient-level information obtained from multiple skin lesions from the same patient. Though artificial intelligence classification algorithms have achieved expert-level performance in controlled studies examining single images, in practice dermatologists base their judgment holistically from multiple lesions
