Occupational Noise-Induced Hearing Loss in Iran: A Systematic Review and Meta-Analysis.

Background: A large portion of Iranian Working Population (IWP) is becoming at risk of Occupational Noise-Induced Hearing Loss (ONIHL). Several primary studies have evaluated the prevalence of ONIHL in Iran with a variety of prevalence rates. We aimed to estimate the prevalence of ONIHL in the IWP using data from relevant studies.

The role of demographic, job-related and psychological characteristics on the prevalence of repetitive patient safety incidents among Iranian nurses.

Background: Job-related psychosocial factors have a substantial effect on the occurrence of adverse events among healthcare professionals.

Objective: An analytical and descriptive survey was conducted to evaluate the relationship between the occurrence of patient safety incidents and psychological factors.

Methods: The study sample consisted of 177 nurses who were asked about patient safety events over six months.

Improvement of natural fiber's properties and evaluation of its applicability as eco-friendly materials in noise pollution control.

Purpose: The use of green and eco-natural fibers due to availability, biodegradability, reasonable cost, and non-toxic effects are known as potential acoustic materials in research. Nevertheless, in this area, the use of chemical treatment in natural fibers as an effective strategy to improve the overall properties and acoustic performance is faced with limitations. So that the current paper aims to investigate the effect of alkali treatment on the mechanical and acoustical properties of jute fibers and evaluation of its applicability in noise pollution control.

The effect of traffic noise on cognitive performance with regard to personality traits: A laboratory experiment study.

Background: Exposure to traffic noise could play an important part in inducing psychological disorders which in turn can affect individuals' cognitive and mental performance.

Objective: The aim of this study was to determine the effect of traffic noise exposure on the cognitive performance with regard to subjects' personality traits.

Methods: Sixty students with normal hearing and vision took part in this experimental study.

Relationships Between Job Satisfaction and Job Demand, Job Control, Social Support, and Depression in Iranian Nurses.

Background: Nurses often experience a wide variety of stressful situations. Excessive work stress influences the physical and mental health of nurses and decreases their life quality and professional efficacy. In addition, high levels of psychological stress may cause job dissatisfaction and job strain.

Effect of long-term occupational exposure to extremely low-frequency electromagnetic fields on proinflammatory cytokine and hematological parameters.

The present study aimed to investigate the effect of extremely low-frequency electromagnetic fields (ELF-EMFs) on proinflammatory cytokines and hematological parameters, among the employees of a power plant, which are one of the most important occupational groups exposed to ELF-EMFs extensively. The studied population included 112 employees of a power plant as the exposed group and 138 unexposed employees who were enrolled based on inclusion and exclusion criteria. The magnetic flux density and the strength of the electric field were determined by spot measurements and according to the IEEE C95.

The associations of workload, individual and organisational factors on nurses' occupational injuries.

Aims And Objectives: To determine the prevalence and type of occupational injuries in nurses and their associations with workload, working shift, and nurses' individual and organisational factors.

Background: Nurses are vulnerable to occupational injuries due to the nature of their job.

Design: A cross-sectional correlational design (based on STROBE Statement) was conducted.

Serum Homocysteine Level in Parkinson's Disease and Its Association with Duration, Cardinal Manifestation, and Severity of Disease.

Background And Purpose: Due to the high prevalence of Parkinson's disease (PD) in the elderly, a large financial burden is imposed on the families and health systems of countries in addition to the problems related to the mobility impairment caused by the disease for the patients. Studies on controversial issues in this disease are taken into consideration, and one of these cases is the role of serum homocysteine level in Parkinson's patients. In this study, the serum level of homocysteine and its association with various variables in relation to this disease was compared with healthy individuals.

Evaluating the relationship between job stress and job satisfaction among female hospital nurses in Babol: An application of structural equation modeling.

This study was designed to investigate job satisfaction and its relation to perceived job stress among hospital nurses in Babol County, Iran. This cross-sectional study was conducted on 406 female nurses in 6 Babol hospitals. Respondents completed the Minnesota Satisfaction Questionnaire (MSQ), the health and safety executive (HSE) indicator tool and a demographic questionnaire.

Effects of patient-handling and individual factors on the prevalence of low back pain among nursing personnel.

Background: Patient-handling is one of the main tasks of nursing personnel; it imposes compressive and shear forces on nurses' lower spine. The aim of this study was to determine the prevalence of Low Back Pain (LBP), risk factors in the incidence of such disorders, and patient handling risk assessment among nursing personnel.

Methods: This study was carried out on 243 randomly selected nursing personnel who played a role in handling the patients (58 wards).
