OBJECTIVES: In recent years numerous initiatives aimed at reducing air pollution have been undertaken in Poland. The general objective was to examine the correlation between air pollution measured by the level of particulate matter ≤10 μm in diameter (PM10 ) and emergency hospitalizations due to chronic obstructive pulmonary disease (COPD) and asthma in 16 Polish cities (capitals of the regions). MATERIAL AND METHODS: The authors aimed to diagnose the situation across 16 cities over a 5‑year period (2014-2019)...

OBJECTIVES: The purpose of the current study was to explore the effects of a mobile health (mHealth) intervention based on the Persuasive System Design (PSD) model on health-related outcomes among office workers. MATERIAL AND METHODS: The authors conducted a trial that consisted of a 4-week baseline and an 8-week intervention period by reference to 23 office workers in a private research company. The mHealth application was developed to improve these workers' daily step count, decrease their sedentary time, and increase their sleep duration in accordance with the PSD model...

The aim was to evaluate if rehabilitation procedures including occupational health (OH) and workplace participation increase return to work (RTW) rates among patients with subacute and chronic low back pain (LBP). A systematic review of randomized controlled trials was conducted using the PubMed and Cochrane databases. Main outcomes were RTW and days of sick leave. Interventions needed to be multidisciplinary including both OH and active workplace involvement in rehabilitation. Out of 1073 potentially eligible references, 8 met the inclusion criteria...

OBJECTIVES: This study aimed to evaluate cytogenetic damage in the buccal mucosa of non-exposed subjects (N = 33) and insecticide-exposed fumigators (N = 31) in the urban area of Cali, Colombia. MATERIAL AND METHODS: Through a questionnaire sociodemographic data, anthropometric measurements, state of health, and lifestyle were collected. Buccal micronucleus cytome (BMCyt) assay was using for evaluate cytogenetic damage. RESULTS: The study showed that all fumigators used adequate personal protective equipment (PPE) and had low alcohol consumption...

OBJECTIVES: Aim of this study was to assess and compare health, quality of life, well-being, job satisfaction and job insecurity between nurses, in a tertiary hospital in Greece, working either under permanent or temporary contract. MATERIAL AND METHODS: In this cross-sectional study, consecutively recruited nurses answered a structured questionnaire, the WHO-5 Well-being Index (WHO-5), the Job Insecurity Index (JII), the Work Ability Index (WAI), and the Well-Being at Work Scale (WBWS)...

OBJECTIVES: Fatigue can be the result of overexertion and overload. It occurs when the burdened body does not have enough time for regeneration and biological renewal. The aim of this study was analysis of fatigue based on the subjective feeling in physiotherapists, nurses, and paramedics. MATERIAL AND METHODS: The research covered 193 women and 107 men aged 30-60 years, including 100 physiotherapists, 100 nurses and 100 paramedics with higher education, employed in clinics and hospitals in the Podkarpackie Voivodeship, Poland...

OBJECTIVES: The circadian system is the main regulator of almost all human physiological processes. The aim of this study was to assess sleep in the working population, in relation to the share of remote working. MATERIAL AND METHODS: An online survey was conducted among students and staff representing 3 universities in Łódź, Poland (N = 1209). The participants were divided into 3 groups according to the percentage of time they worked remotely. Group I consisted of respondents performing tasks remotely for ≤45% of their working time; group II included respondents performing their duties remotely for >45-75% of their working time, and group III included those working >75% of their time remotely...

OBJECTIVES: Head and neck cancer (HNC) is one of the most common cancers. Most exogenous HNC is head and neck squamous cell carcinomas. Scientists are striving to develop diagnostic tests that will allow the prognosis of HNC. The aim of the study was to determine the risk of HNC. The research concerned changes caused by polymorphisms in genes encoding proteins responsible for the metabolism of xenobiotics. MATERIAL AND METHODS: In group of 280 patients with HNC, the occurrence of polymorphic variants in NAT1 (rs72554606), NAT2 (rs1799930), CYP1A (rs1799814), CYP2D (rs3892097) were studied with TaqMan technique...

OBJECTIVES: Laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) has considerable applicative potential for both qualitative and quantitative analyses of elemental spatial distribution and concentration. It provides high resolutions at pg-level detection limits. These qualities make it very useful for analyzing biological samples. The present study responds to the growing demand for adequate analytical methods which would allow to assess the distribution of nanostructured molybdenum(IV) disulfide (MoS2 ) in organs...

OBJECTIVES: The effect of the combination of working hours and working time mismatch on depression is unknown. This study was undertaken to confirm the relationship between working time mismatch and depression with respect to hours worked. MATERIAL AND METHODS: The data of 45 514 adult workers that participated in the 6th Korean Working Conditions Survey (KWCS-VI 2020) were reviewed. Depression was defined using the World Health Organization 5 Well-Being Index (WHO-5) cut-off score of 50...

OBJECTIVES: The authors used the National Aeronautics and Space Administration Task Load Index (NASA-TLX) and general health questionnaire to analyze the factors influencing the mental health status and the workload of support nurses during the COVID-19 epidemic. MATERIAL AND METHODS: The authors conducted a cross-sectional survey of 349 support nurses in April-October 2022. Using QuestionStar, a powerful online survey tool, the authors administered surveys to the participants, collected data on the mental health status and workload of support nurses, and analyzed the influencing factors based on the collected data...

OBJECTIVES: Hearing loss is a major worldwide health issue affecting an estimated 1.5 billion people. Causes of hearing loss include genetics, chemicals, medications, lifestyle habits such as smoking, and noise. Noise is probably the largest contributing factor for hearing loss. Noise arises from the workplace, ambient environment, and leisure activities. The easiest noise sources to control are workplace and environmental. Workplace noise is unique in that the employer is responsible for the noise and the worker...

OBJECTIVES: The nitrogen-containing xenobiotics, such as nitrates and acrylamide may potentially influence systemic redox status and contribute to the generation of oxidative stress (OS) in the human body, but there is still a lack of studies that would evaluate the various parameters assessing the oxidative-antioxidant balance. The aim of this study was to evaluate the exposure to nitrates and acrylamide derived from daily diet and to analyze the impact of these nitrate-containing xenobiotics on the parameters of systemic redox status in healthy young adults...

OBJECTIVES: Academic burnout poses a challenge to the educational process. Higher education institutions have responsibilities similar to the ones of management in business settings. These institutions are responsible for creating conditions conducive to development and, as such, may be interested in verifying the presence of student burnout and pinpointing its causes. The purpose of this study was to answer these needs and develop a scale to measure the effect of organizational factors that may predict student burnout...
