Background: This study was conducted to investigate ocular biometry parameters in cataract surgery candidates in northern Tehran, Iran using OA-2000 biometry device.
Methods: In this cross-sectional study, values of ocular biometry parameters, including axial length (AL), anterior chamber depth (ACD), mean corneal curvature (mean K), lens thickness (LT), corneal astigmatism (CA), and white-to-white (WTW) of 818 eyes with cataracts, were measured using the OA-2000 biometry device (Tomey, Nagoya, Japan). The participants were divided into si age subgroups, in 10-year intervals. Finally, the values of the biometry parameters were calculated, and the trend of changes was examined for both age and sex subgroups.
Results: The mean (standard deviation [SD]) of age of the participants was 63.82 (13.25) years. Mean (SD) of biometry parameters were as follows: AL, 23.36 (1.55) mm; ACD, 3.09 (0.40) mm; LT, 4.45 (0.55) mm; mean K, 44.51 (1.72) D; CA, 1.06 (0.94) D; and WTW, 11.81 (0.45) mm. Most of the parameters showed significant age-related changes in the total population. There was an increase in LT ( < 0.001) and mean K ( = 0.001), as well as a decrease in AL ( < 0.001) and ACD ( < 0.001) with age. Moreover, AL had a negative negligible correlation with LT (r = - 0.24; < 0.001) and mean K (r = - 026; < 0.001), as well as a weak positive correlation with ACD (r = + 0.44; < 0.001).
Conclusions: Our study revealed that the mean values of most biometric parameters varied across age and sex subgroups. Moreover, most of the parameters showed significant age-related changes in the total population.

To study the correlation between myopia growth and physical development of primary school student in Shihezi area of Xinjiang Uyghur Autonomous Region by measuring the ocular biometry and physical parameters of the eye, and to provide an objective basis for the development of myopia prevention and control. A cross-sectional study design was used. The Grade 1-6 students from 33 schools in Shihezi area were randomly selected in October 2023.

Purpose: Staging of non-small cell lung cancer (NSCLC) is commonly based on [F]FDG PET/CT, in particular to exclude distant metastases and guide local therapy approaches like resection and radiotherapy. Although it is hoped that PET/CT will increase the value of primary staging compared to conventional imaging, it is generally limited to the characterization of TNM. The first aim of this study was to evaluate the PET parameter metabolic tumor volume (MTV) above liver background uptake as a prognostic marker in lung cancer.

Objective: The aim of this study is to compare the results of preoperative biometric data measured with optical biometers of different generations in patients with cataract. Lenstar optical biometry is based on the principle of optical low-coherence reflectometry (OLCR), and Anterion on swept-source optical coherence tomography (SS-OCT).
Material And Methods: A total of 200 eyes (103 patients) were included in a prospective study at the Faculty Hospital in Trenčín the period from June 2023 to January 2024.

Introduction: The endoscopic assisted release for cubital tunnel syndrome (CuTS) gained popularity in recent years with unclear long-term results. This study aims to evaluate long term results regarding functional and subjective outcomes after endoscopic assisted release for the CuTS.
Materials And Methods: Thirty one patients who have been treated by endoscopic assisted release for CuTS between 2006 and 2013 were followed up both clinically and with a questionnaire with a mean follow up of 152 months (range 120-204 months).

Vaspin plays a regulatory role in lipid and glucose metabolism and is a therapeutic adipokine against impaired glucose intolerance in obese individuals. We aimed to investigate serum vaspin levels in patients with FMS and whether there was any relationship between vaspin levels and metabolic and clinical parameters in fibromyalgia. A total of 64 female patients who applied to an outpatient clinic due to widespread pain lasting more than three months were included in the study.
