Introduction: Car repair technicians use chemicals during their work. These chemicalsbecome airborne during its application and can be easily inhaled and cause harm to therespiratory system. Aim of work: The current study aims to describe the magnitudeof respiratory symptoms and pulmonary function disorders among automobile repairworkers. Materials and Methods: A cross-sectional descriptive study was performedon 121 automobile repair workers. The workers completed a predesigned questionnaireto collect socio-demographic data, including occupational history, special habits, andrespiratory complaints. The pulmonary function tests were carried out utilizing Spirolab-III from MIR Company with Winspiro Pro software, a calibrated spirometer with abuilt-in computer program. Forced vital capacity (FVC), forced expiratory volume inone second (FEV1), and the ratio of these variables (FEV1/FVC) was measured as apercentage of normal predicted levels according to age, gender, weight, and height.Results: Dry cough and chest tightness were the most common respiratory symptoms(33.9% and 23.1%, respectively); however, only 4% of the automobile repair workersused respiratory protective equipment. More than one-third (38.8%) of the subjectshad pulmonary function (PF) disorders (19% with obstructive patterns and 19.8% withrestrictive patterns). Pulmonary function disorders were common among the older (>30 years), compared to the younger age group (≤30 years) (48.1% vs. 22.7%, respectively)and workers who are exposed to brake fluid. Smoking, obesity, and a long duration ofemployment had no significant associations with PF disorders. Conclusion: The currentstudy showed that two out of five car mechanics exhibited changes in pulmonary functionsthat were equally distributed between obstructive and restrictive impairments. Pulmonaryfunction disorders were common among the older age group, regardless of smoking or along employment duration. The promotion of workplace safety and the periodic spirometryexamination of individuals is required to detect any respiratory changes.

Highlights: The strength of the relationship between respiratory dust levels and pulmonary function disorders could not be obtained. The weakness level of correlation between years of service and pulmonary function disorders. Abstract: Environmental dust in the workplace exposes the workers as they are breathing. The dust is inhaled into the respiratory tract and causes occupational diseases in the form of pulmonary function disorders. Workers in the marble industry are also prone to dust exposure. This study aimed to analyze the correlation between years of service, respiratory dust levels, and pulmonary function disorders in marble home industry workers in Tulungagung Regency, Indonesia. This study was a descriptive observational study with data from a cross-sectional technique. The population was 18 workers taken as respondents. The independent variables in this study were years of service and the level of respirable dust, while the dependent variable was the pulmonary function disorders experienced by the workers. The data were analyzed using the Correlation Contingency test. There was a close correlation between years of service and pulmonary function disorders by 0.196, indicating that the relationship between those variables was weak. The strength of the relationship between respiratory dust levels and pulmonary function disorders could not be obtained because the constant results met the threshold value. The correlation between years of service and pulmonary function disorders was weak, and the relationship between respiratory dust level and pulmonary function disorders could not be obtained.

Abstract. The cement industry is the largest manufacturing industry, vital for sustainable development, and very risky for workers to be exposed to dust in various processes, including production. Continuous exposure to dust can cause pulmonary function disorders. This study aimed to analyze the relationship between dust exposure, age, length of work, working period, use of PPE (masks), smoking habits, and pulmonary function disorders in labor. This research used an observational method with a cross-sectional approach. The research sample was a total population of 38 male workers at Semen X company, engaged in the cement bagging industry as business activities. Data collection was by interviewing respondents, measuring the level of inhaled dust with a personal dust sampler, and checking the lung capacity with a spirometer. Data analysis was performed bivariate with the chi-square test. The results showed that there was a relationship between the use of PPE (mask) (p = 0.006) with pulmonary function disorders.

Dental technicians working in laboratories are exposed to different doses of various dusts. Disorders of pulmonary function may occur before radiographic changes are evident. If these pulmonary function disorders are found at an early stage, the risk may be reduced by early, adequate local ventilation and by appropriate individual protective methods. Unless adequate preventive measures are taken, pulmonary disorders will increase, finally leading to obstructive or restrictive ventilatory disorders, or progressive massive fibrosis. Results of pulmonary function tests provide objective criteria for prognosis, and are a measure of disease disability. In this situation, abnormal pulmonary function results should be considered as alarm signs.

The effect and safety of intrathecal baclofen (ITB) on generalized spasticity of the lower extremity have been well described in numerous studies, whereas the safety and effect on spasticity of the upper extremity during cervical administration seems to be less certain. We aim to establish the safety of cervical administration of ITB on pulmonary function and sleep-related disorders in adults with a cervical spinal cord injury with functional hindering spasticity. In addition, we aim to explore the effect of cervical ITB on the reduction of spasticity; participant satisfaction; and improvement at the level of function, activities, and participation. The study is a multiphase single-arm intervention study. Before the start of the study, participants are screened for the presence of sleep-related disorders, and pulmonary function is assessed using spirometry and a capillary blood gas sample. Participants are allowed to start the first phase of the study if there are no signs of sleep-related disorders or if these are adequately treated. The PcCO2 (partial pressure of CO2 in capillary blood sample) should be between 4.5 and 6.5 kPa. In the first phase of the study, an extracorporeal pump will be used to investigate whether cervical administration of ITB leads to a reduction of spasticity without an adverse effect on pulmonary function and sleep-related disorders. In case of a safe (no adverse effects) and positive (reduction of spasticity) result of the trial, a baclofen pump will be implanted in the second phase of the study. After implantation, the dosage of ITB will be slowly increased, and eventually, the use of oral spasmolytics will be phased out. The dosage will be increased during the monitoring of pulmonary function and sleep-related disorders. In the second phase of the study, a pulse oximetry will be performed, and pulmonary function; spasticity; satisfaction; and the level of function, activities, and participation will be assessed at 3, 6, and 12 months after definitive implantation of the baclofen pump. The first participant was recruited on May 23, 2023. Data collection and analyses are expected to be completed in 2027. Currently, little is known about the safety and effectiveness of cervical administration of ITB for the treatment of upper extremity spasticity. We aim to establish the safety and explore the efficacy of this procedure. This paper describes the protocol of this study. DERR1-10.2196/70362.

Lung function disorders are among the occupational health problems frequently experienced by workers in industries exposed to chemicals, dust, and vapors generated during production processes. The printing area represents a work environment with a high potential for exposure to chemicals such as organic solvents (toluene, xylene, and formaldehyde), fine particulates, and combustion gases. The purpose of this study, Factors Associated with Pulmonary Function Disorders Among Workers in the Printing Area of PT X, is to identify and analyze factors related to impaired lung function among workers in the printing area based on a literature review. The method used is a systematic literature review involving article searches in the PubMed, ScienceDirect, ProQuest, and Google Scholar databases from 2013 to 2023. The synthesis results showed that work duration, exposure period, smoking habits, use of personal protective equipment, workspace ventilation, and concentrations of airborne chemicals were significantly associated with decreased pulmonary vital capacity (FVC) and first-second forced expiratory volume (FEV?). Continuous risk management efforts, including routine spirometry examinations, worker education, and ventilation engineering, are essential to reduce the risk of lung disorders in the printing industry.

Background: Brickmakers have a high risk of occupational lung diseases. Dust particles that are inhaled continuously for a long time and exceed the Threshold Limit Value (TLV) can cause lung damage. When inhaled particles are not efficiently cleared from the lungs, damaged macrophages will activate Reactive Oxygen Species (ROS), Reactive Nitrogen Species (RNS), chemokines, and cytokines. Interleukin-4 (IL-4) produced by T helper-2 (Th2) then stimulates tissue proliferation and remodeling. Inflammation may occur as a result of either changes in epithelial permeability or mucus hypersecretion is associated with pulmonary function disorders. Methods: We conducted an observational analytic study among brickmakers in Badung, Bali with 24 subjects. Therefore, IL-4 levels and lung function were examined. The cumulative dose of dust is determined by multiplying the Total Suspended Particles (TSP) and the exposure time. Total Suspended Particles were measured using the gravimetric method with a Middle Volume Sampler (MVS). The association was analysed using Chi Square test, and then Relative Prevalence (PR) was assessed. Results: A significant relationship was found between high cumulative doses of dust and pulmonary function disorder (p = 0.018). High-exposed workers have an 11.4 times greater risk of experiencing lung function disorders compared to a low cumulative dose of dust. However, there was no significant relationship between the cumulative dose of dust and IL-4 levels (p = 1.00). Conclusion: Our results suggested a significant association between the cumulative dose of brick dust with lung function but no significant association with IL-4 levels.

Objective To investigate the clinical efficacy and application value of preoperative progressive pneumoperitoneum treatment for patients with complex abdominal wall defects. Methods Nine patients with complex abdominal wall defects were conducted preoperative progressive pneumoperito-neum. Retrospective analysis of the clinical data and therapeutic effect of these patients from January 2013 to June 2015 were carried out. Patients were treated with progressive pneumoperitoneum for 2-3 weeks.

Introduction Respiratory failure is a major cause of death in patients with Osteogenesis Imperfecta. Moreover, respiratory symptoms seem to have a dramatic impact on their quality of life. It has long been thought that lung function disorders in OI are mainly due to changes in the thoracic wall, caused by bone deformities. However, recent studies indicate that alterations in the lung itself can also undermine respiratory health. Objectives Is there any intrapulmonary alteration in Osteogenesis Imperfecta that can explain decreased pulmonary function? The aim of this systematic literature review is to investigate to what extent intrapulmonary or extrapulmonary thoracic changes contribute to respiratory dysfunction in Osteogenesis Imperfecta. Methods A literature search (in PubMed, Embase, Web of Science, and Cochrane), which included articles from inception to December 2020, was performed in accordance with the PRISMA guidelines. Results Pulmonary function disorders have been described in many studies as secondary to scoliosis or to thoracic skeletal deformities. The findings of this systematic review suggest that reduced pulmonary function can also be caused by a primary pulmonary problem due to intrinsic collagen alterations. Conclusions Based on the most recent studies, the review indicates that pulmonary defects may be a consequence of abnormal collagen type I distorting the intrapulmonary structure of the lung. Lung function deteriorates further when intrapulmonary defects are combined with severe thoracic abnormalities. This systematic review reveals novel findings of the underlying pathological mechanism which have clinical and diagnostic implications for the assessment and treatment of pulmonary function disorders in Osteogenesis Imperfecta. KEY MESSAGES Decreased pulmonary function in Osteogenesis Imperfecta can be attributed to primary pulmonary defects due to intrapulmonary collagen alterations and not solely to secondary problems arising from thoracic skeletal dysplasia. Type I collagen defects play a crucial role in the development of the lung parenchyma and defects, therefore, affect pulmonary function. More awareness is needed among physicians about pulmonary complications in Osteogenesis Imperfecta to develop novel concepts on clinical and diagnostic assessment of pulmonary functional disorders.

This reserach aims to examine whether the characteristics of workers, the job and the total levels of inhaled particles are risk factors for pulmonary function disorders on car painting workers. The type of this research was observational research with a cross sectional design. The population were car painting workers in Palu. The sample were 96 workers selected using simple random sampling. The researcher used a questionnaire to collect smoking status data, number of cigarettes a day, working period, total of working hours and the use of masks. The researcher also uses a spirometer to measure pulmonary function variables with the Mod Mode of Dat 120B. The results showed a relationship between the use of masks and pulmonary function (p-value = 0.021) is weak relationship (Phi coefficient ϕ = 0.23); the relationship between working period and pulmonary function (p-value = 0.015) is weak relationship (Phi coefficient ϕ = 0.28) the prevalence ratio 3.33 (95% CI = 1.33-8.36); while the factors of smoking habits, total of working hours and the use of masks are not significantly related to pulmonary function. Thus, it can be concluded that the use of masks and working period are risk factors for pulmonary disorders. So that workers are advised to use masks and regulate working hours to prevent the risk of pulmonary disorders.Keywords : Pulmonary function disorders, masks, working hours

The aim of this study was to investigate the respiratory function disorders that could be related to dust exposure during the production of copper mine in copper mineworkers (CMWs). The study included 75 male CMWs (mean age, 32.0 ± 7.1 years, 58.6% smokers) and 75 male age- and smoking status-matched healthy control subjects. Serum Cu level was significantly higher in the CMW group (0.80 ± 0.62 μg/ml) than the control group (0.60 ± 0.39 μg/ml) (p = 0.017). Significant negative correlations were found between serum Cu level and forced expiratory volume in first second (r = -0.600; p < 0.001) and between serum Cu level and forced vital capacity (r = -0.593; p = <0.001) in CMWs. Serum Cu level was significantly higher in the restrictive type pulmonary function disorders group (1.36 ± 0.62 μg/ml) than obstructive type (0.90 ± 0.55 μg/ml) and normal pulmonary function pattern group (0.53 ± 0.43 μg/ml) (p < 0.001). Patients with radiological parenchymal abnormalities had significantly higher serum copper levels than those without abnormalities (1.53 ± 0.52 vs. 0.71 ± 0.52 μg/ml, respectively; p = 0.002). In conclusion, result of the study has shown a negative association between pulmonary functions disorders and radiological abnormalities and serum Cu levels in CMWs.
