Methods: A total of 20 healthy controls and 58 patients with confirmed COVID-19 were enrolled in this prospective study.

Cognitive assessment of patients with nonalcoholic fatty liver disease.

Objective: The aim of this study was to investigate cognitive performance for the first time in participants with nonalcoholic fatty liver disease (NAFLD) using the Montreal Cognitive Assessment (MoCA).

Participants And Methods: In total, 70 participants with NAFLD and 73 age-matched and sex-matched healthy participants were enrolled in this prospective cross-sectional study. The diagnosis of NAFLD was made on the basis of abdominal ultrasonography findings.

Association Between Overactive Bladder and Polyneuropathy in Diabetic Patients.

Purpose: Diabetes mellitus (DM) is a chronic metabolic disorder that often leads to complications. We aimed to correlate two complications of DM, polyneuropathy and hyperactive bladder syndrome, using noninvasive measures, such as screening tests.

Methods: We included 80 female and 40 male type 2 diabetic patients in this prospective study.

Does vitamin D deficiency trigger carpal tunnel syndrome?

Objective: Vitamin D deficiencies are associated with a variety of chronic diseases. The goal of the present study was to investigate the relationship between vitamin D levels and carpal tunnel syndrome (CTS).

Methods: This study included 90 patients with mild to moderate CTS and assessed their routine serum 25-hydroxyvitamin D levels.

Pain, depression and sleep disorders in patients with diabetic and nondiabetic carpal tunnel syndrome: a vicious cycle.

Unlabelled: Carpal tunnel syndrome (CTS) is a condition involving nerve entrapment that often leads to chronic neuropathic pain. We aimed to evaluate sleep quality and related parameters in diabetic and non-diabetic CTS patients.

Method: This study included a total of 366 patients with chronic CTS.

Associations of olfactory bulb and depth of olfactory sulcus with basal ganglia and hippocampus in patients with Parkinson's disease.

Parkinson's disease (PD) is a neurodegenerative disorder characterized by hyposmia in the preclinical stages. We investigated the relationships of olfactory bulb (OB) volume and olfactory sulcus (OS) depth with basal ganglia and hippocampal volumes. The study included 25 patients with PD and 40 age- and sex-matched control subjects.

Cognitive Impairment in Patients with Psoriasis: A Cross-Sectional Study Using the Montreal Cognitive Assessment.

Background: Psoriasis is a multisystem chronic inflammatory disorder that is thought to be associated with cognitive impairment.

Aims: We aimed to investigate cognitive performance using the Montreal Cognitive Assessment (MoCA) in patients with psoriasis.

Methods: In total, 77 patients with psoriasis and 83 age- and sex-matched control subjects were enrolled in this prospective cross-sectional study.

Olfactory bulb and olfactory sulcus depths are associated with disease duration and attack frequency in multiple sclerosis patients.

Background And Purpose: Multiple sclerosis (MS) is a neuroinflammatory and neurodegenerative disease that progresses to axonal loss and demyelinization. Olfactory dysfunction in patients with MS has been reported frequently. We were interested in the associations of olfactory bulb (OB) and olfactory sulcus depth (OSD) with disease duration and attack frequency.

Retinol-binding protein-4 and hs-CRP levels in patients with migraine.

Retinol-binding protein-4 (RBP4) and high-sensitivity C-reactive protein (hs-CRP) levels are associated with inflammation in patients with migraine. The release of proinflammatory cytokines during migraine results in recurrent sterile neurogenic inflammation. This study aimed to determine the correlation between RBP4 and hs-CRP levels, and migraine, which is considered an inflammatory disease.

Iliac arteriovenous fistula presenting with ascites.

Arteriovenous fistula presents rarely with ascites. Diagnosis, with an elusive clinical presentation, is often incidental or delayed. A 35-year-old woman presented with ascites and cardiac decompensation.

The effects of caffeic acid phenethyl ester on inflammatory cytokines after acute spinal cord injury.

Background: The purpose of this study was to investigate the effects of Caffeic Acid Phenethyl Ester (CAPE) on proinflammatory cytokines, IL-1ß and TNF-α, and explore its healing effect after acute spinal cord injury.

Methods: Forty-eight male Wistar-Albino rats were used in this study which was planned as three groups. All groups were divided into two sub-groups.

The relationship between oxidative stress markers and visual evoked potentials in different hypertension models.

Objective: We aimed to define the influence of different hypertension models on lipid peroxidation markers [conjugated dienes (CD) and thiobarbituric acid-reactive substances (TBARS)], antioxidant protection [paraoxonase-1 (PON1) activity] and visual evoked potential (VEP) changes in rats.

Methods: The study was designed as four different hypertension models. Rats (n=84) were divided equally into six groups: Control group (C), Sham operated (Sham), Two kidney-one clip (2K-1C), One kidney-one clip (1K-1C), Deoxycorticosterone acetate (DOCA) and N-omega-nitro-L-arginine-methyl ester (L-NAME).
