Association between diffusion tensor imaging measurements and cognitive performances in people with multiple sclerosis: A systematic review and meta-analysis.

Background: Alterations in structural connectivity of brain networks have been linked to complex cognitive functions in people with multiple sclerosis (PwMS). However, a definitive consensus on the optimal diffusion tensor imaging (DTI) markers as indicators of cognitive performance remains incomplete and inconclusive. This systematic review and meta-analysis aimed to explore the evidence on the correlation between DTI metrics and cognitive functions in PwMS.

Functional MRI and cognition in multiple sclerosis-Where are we now?

Multiple sclerosis-related cognitive impairment (MSrCI) affects most patients with multiple sclerosis (MS), significantly contributing to disability and socioeconomic challenges. MSrCI manifests across all disease stages, mainly impacting working memory, information processing, and attention. To date, the underlying mechanisms of MSrCI remain unclear, with its pathogenesis considered multifactorial.

Asthma and chronic obstructive pulmonary disease (COPD) in people with multiple sclerosis: A systematic review and meta-analysis.

Background: Studies have found that multiple sclerosis (MS) has an impact on the initiation or the course of asthma and chronic obstructive pulmonary disease (COPD). This review amied to investigate the prevalence and odds of asthma and COPD among people with MS (pwMS).

Method: PubMed, Embase, Scopus, and Web of Science were systemically searched from inception to May 2023.

Alemtuzumab-induced petechiae and epistaxis in a patient with relapsing-remitting multiple sclerosis: A case report.

Here, we present a case of relapsing-remitting multiple sclerosis that experienced petechiae and epistaxis following treatment with second dose of alemtuzumab. This study highlights such effects, emphasizing the need for vigilance as alemtuzumab usage increases. Timely recognition and management are vital for patient care.

XRayWizard: Reconstructing 3-D lung surfaces from a single 2-D chest x-ray image via Vision Transformer.

Background: Chest x-ray is widely utilized for the evaluation of pulmonary conditions due to its technical simplicity, cost-effectiveness, and portability. However, as a two-dimensional (2-D) imaging modality, chest x-ray images depict limited anatomical details and are challenging to interpret.

Purpose: To validate the feasibility of reconstructing three-dimensional (3-D) lungs from a single 2-D chest x-ray image via Vision Transformer (ViT).

Predictors of survival rate in patients with pancreatic cancer: A multi-center analytical study in Iran.

Background: Pancreatic cancer (PC) is among the deadliest cancers of the gastrointestinal tract worldwide and a growing global health concern.

Aim: This study was aimed to evaluate the survival rate and prognostic factors of survival in patients with PC.

Methods: In this retrospective cohort study, the records of 556 patients with PC registered in the hospital cancer registration system from September 2007 to September 2020 were evaluated.

Association of Matrix Metalloproteinase-2 and Matrix Metalloproteinase-9 With Endothelial Dysfunction, Cardiovascular Disease Risk Factors and thrombotic events in Children With End-stage Renal Disease.

Introduction: Cardiovascular disease (CVD) is the main cause of death in children with end-stage renal disease (ESRD). Matrix metalloproteinases (MMP-2 and MMP-9) are members of endopeptidases which contribute to CVD. The aim of this study was to evaluate the association of MMP-2 and MMP-9 with markers of endothelial dysfunction, soluble E-selectin and brachial flow-mediated dilatation; several biochemical risk factors of CVD; and thrombotic incidents in children with ESRD.

First Report on the Percentiles of the Glomerular Filtration Rate in Iranian Children Using the 2009 Schwartz Equations.

The glomerular filtration rate (GFR) is widely considered the best overall index of renal function. The Schwartz equations are designed for measuring the GFR in children between 1 and 16 years of age. In the present study, we investigated the percentiles of the GFR in a general population of Iranian children with no known renal disease via the 2009 Schwartz equations (updated and combined equations).

Herpes zoster segmental paresis in an immunocompromised breast cancer woman.

Herpes zoster is an infectious disease with neurological complications caused by reactivation of varicella zoster virus in dorsal root ganglia of spinal cord which is also known as "Shingles." Suppression of immune system is the major predisposing factor for reactivation of latent virus. Disease is mainly characterized by rash, vesicles and pain along one or more dermatomes which are innervated from one or more spinal nerve roots.
