Predictive power of the eTBI score for 30 day outcome in elderly patients with traumatic brain Injury.

Traumatic brain injury (TBI) is a common problem in elderly individuals, with significant morbidity and mortality. The elderly Traumatic Brain Injury (eTBI) score, a novel tool for predicting outcomes in elderly patients with TBI, has shown promising results in previous studies. This study aimed to validate the eTBI score in a larger cohort of elderly patients with TBI in the Middle East.

Spinal Cord Tumors: A Review of Demographic Characteristics and Treatment Follow-Up of Patients in Isfahan City, Iran.

Background: Given that spinal cord tumors cause damage to the central nervous system, the involvement of body organs, patients' reduced quality of life, and the follow-up of patients should be performed with more sensitivity. Therefore, the present study aimed to determine the demographic characteristics and treatment follow-up of patients with spinal cord tumors.

Materials And Methods: The present descriptive-analytical and cross-sectional study investigated all patients with spinal cord tumors in 2022 who visited the Kashani Hospital Isfahan.

Citicoline on the Barthel Index: Severe and moderate brain injury.

Introduction: Traumatic brain injury (TBI) is a paramount factor in mortality and morbidity. The clinical trials conducted to investigate the efficacy of neuroprotective agents, such as citicoline, as a therapeutic alternative for TBI have presented divergent findings. Therefore, this study aimed to evaluate and compare citicoline's effect on the Barthel Index in patients with severe and moderate brain injury.

The impact of body mass index changes on traumatic brain injury patients' outcomes during hospitalization.

Purpose: Obesity is a complex multifactorial disease with increasing prevalence worldwide. The present study was conducted, since there were different results on the effect of obesity on the prognosis of patients with moderate and severe brain trauma, and the issue was less investigated.

Methods: The present descriptive-analytical study was conducted in 2 hospitals, Al-Zahra and Kashani in year 2022.

Predictors of radiological contusion progression in traumatic brain injury.

Background: Traumatic brain injury, mainly caused by the unintentional falls and motor vehicle accidents, is a serious condition encompassing a spectrum of pathological features from axonal to hemorrhagic injuries. Among these, cerebral contusions significantly contribute to death and disability following the injury and occur in up to 35% of cases. This study aimed to investigate the predictors of radiological contusion progression in traumatic brain injury.

Basilar Skull Fractures and Their Complications in Patients With Traumatic Brain Injury.

Objective: Since traumatic brain injury is more common in young people, who are the main workforce and builders of society, it is important to consider the effects caused by brain injury on them. In this study, we investigated the clinical manifestations, complications, and prognosis of patients with basilar skull fractures.

Methods: This cross-sectional study was conducted from March 2021 to March 2022 at the Kashani Hospital, Esfahan, Iran.

Comparison between rivaroxaban versus enoxaparin for venous thromboembolism prophylaxis following spine surgeries, a randomized clinical trial.

Background: Enoxaparin is currently used for VTE prophylaxis. Rivaroxaban is more cost-effective and is as potent as enoxaparin in VTE prophylaxis.

Methods: The study was held at Al-Zahra and Kashani university hospitals in Isfahan, Iran, from January 2019 to October 2020.

Systemic Sclerosis, Reversible Cerebral Vasoconstriction Syndrome, and NeuroMyelitis Optica in a Patient.

Systemic sclerosis (SSC) is an autoimmune disease of connective tissue and microvasculature mostly caused by autoantibodies. Likewise, neuromyelitis optica (NMO) is a demyelinating disease of the central nervous system correlating with autoantibodies against aquapourin-4. Reversible cerebral vasoconstriction syndrome (RCVS) is a disorder of brain vasculature resembling Raynaud phenomena in SSC.

Atlantoaxial instability and cervical noninfectious spondylodiscitis in a patient with Wegener's granulomatosis: A case report.

A 61-year-old male patient with Wegener's granulomatosis was admitted due to neck pain and quadriparesis. Clinical evaluation showed severe cervical noninfectious spondylodiscitis, myelopathy, sagittal imbalance, and atlantoaxial instability. A combined anterior and posterior approach was implemented.

Comparison of subcutaneous pocket with cryopreservation method for storing autologous bone flaps in developing surgical wound infection after Cranioplasty: A randomized clinical trial.

Background: Following a decompressive craniectomy (DC), the harvested bone flap is stored for future cranioplasty. There are two different methods proposed for bone banking, namely subcutaneous pocketing (SP) in the abdominal wall and cryopreservation (CP) in a refrigerator. This study was designed to evaluate the risk of developing infection in each study group.

Seroprevalence of hepatitis B before marriage: a study on marriage candidates in the Southeast of Iran; is it worthy of consideration?

Objectives: Hepatitis B virus infection is one of the most common causes of acute and chronic hepatitis worldwide. Furthermore, since most people with hepatitis B virus are asymptomatic, timely diagnosis is important for prevention. This study has evaluated the prevalence of Hepatitis B seromarkers in marriage candidates.

Challenges in the Area of Training and Prevention at the HIV Triangulation Clinic, Kerman, Iran.

Background: Since 2000, Iran has been delivering training and treatment services, including methadone therapy, to human immunodeficiency virus (HIV) positive patients through triangular clinics. This study aims to evaluate the effectiveness of these activities at the HIV Triangulation Centre in the city of Kerman, Iran, through clients' views.

Methods: Participants were recruited using a convenience sample and assessed through in-depth interviews, and observations.

Low-threshold bistability in nonlinear microring tower resonator.

Microring tower resonators, which are a chain of microring resonators stacked on top of each other, are of great interest for nonlinear optics due to their unique features such as very high compactness, coupling efficiency and quality factor. In this research, we investigate the optical bistability in microring tower (MRT) with Kerr nonlinearity by using the coupled mode theory, and demonstrate how a proper defect into the structure can lead to low threshold bistability. In particular, we observed optical bistability in nonlinear defect modes with switching power as low as 165 μW through numerical calculations in a structure with a overall loss on the order of 0.

Spironolactone in preventing hypokalemia following traumatic brain injury.
