ABSTRACT

A análise do perfil de saúde dos profissionais de saúde é necessária em ambientes hospitalares devido ao nível de insalubridade apresentado nesses locais. Assim, o objetivo deste estudo foi investigar o perfil de saúde, nível de atividade física e exposição a telas de trabalhadores de um hospital no Sul do Brasil. Este estudo tem caráter transversal e descritivo, e a amostra utilizada foi composta por trabalhadores adultos de um hospital universitário do Sul do Brasil. Os resultados indicaram que a maioria eram mulheres, brancas, de 35-44 anos, com especialização, renda de três a seis salários mínimos, percepção de bem-estar "boa" a "regular", índice de massa corporal "eutrófico" a "sobrepeso", sem doenças crônicas, não fumantes, com sono irregular, ansiedade em níveis normais, saúde percebida como "boa", sedentários, com mais de seis horas de tempo sentado em dias de trabalho. Foram encontradas associações entre ansiedade e várias variáveis. Embora com aspectos positivos, destaca-se que os trabalhadores apresentaram fatores de riscos à saúde, como sedentarismo, tempo prolongado sentado e dor corporal leve e sono irregular. Intervenções em saúde como diminuição de sedentarismo promovendo a prática de atividade física, redução de tempo sentado e orientações para manejo do sono e alívio de dores são necessárias nesse ambiente.


Analyzing the health profile of healthcare professionals is necessary in hospital environments due to their level of unhealthy conditions. Thus, this study investigated the health profile, level of physical activity, and screen exposure of workers at a hospital in southern Brazil. A cross-sectional descriptive was conducted with adult workers from a university hospital in southern Brazil. Results indicated that most participants were white women aged 35 to 44 years with specialization, an income of three to six minimum wages, well-being perceived as "good" to "regular", "eutrophic" to "overweight" body mass index, without chronic diseases, non-smokers, with irregular sleep, anxiety at normal levels, health perceived as "good," sedentary, sitting for more than six hours on work days. Associations were found between anxiety and several variables. Despite positive aspects, workers presented health risk factors such as a sedentary lifestyle, prolonged sitting, mild body pain, and irregular sleep. Health interventions to reduce sedentary lifestyles by promoting physical activity, to reduce sitting time, and to guide sleep management and pain relief are necessary in this setting.


El análisis del perfil de salud de los profesionales de la salud es importante en el ámbito hospitalario debido al nivel de condiciones de insalubridad en estos lugares. Así, el objetivo de este estudio fue evaluar el perfil de salud, el nivel de actividad física y la exposición a pantallas por parte de los trabajadores de un hospital del Sur de Brasil. Este es un estudio transversal y descriptivo, y la muestra estuvo compuesta por trabajadores adultos de un hospital universitario del Sur de Brasil. Los resultados indicaron que la mayoría eran mujeres, blancas, de entre 35 y 44 años, con especialización, ingresos de tres a seis salarios mínimos, percepción de bienestar "bueno" a "regular", índice de masa corporal "eutrófico", "sobrepeso", sin enfermedades crónicas, no fumadores, con sueño irregular, ansiedad en niveles normales, salud percibida como "buena", sedentarios, con más de seis horas sentados en días laborales. Se encontraron asociaciones entre la ansiedad y varias variables. Aunque existen aspectos positivos, se destaca que los trabajadores presentaron factores de riesgo para la salud, como sedentarismo, estar sentado durante mucho tiempo, dolores corporales leves y sueño irregular. En este entorno son necesarias intervenciones sanitarias, como la reducción del estilo de vida sedentario mediante la promoción de la actividad física, la reducción del tiempo sentado y la orientación sobre el manejo del sueño y el alivio del dolor.

ABSTRACT

INTRODUCCIÓN: La comprensión del comportamiento de la respuesta humoral en COVID-19 continúa siendo un desafío para la producción de vacunas que proporcionen inmunidad más duradera. OBJETIVO: Describir la respuesta humoral natural inducida por SARS- CoV-2 en personal de salud con base en el perfil epidemiológico y clínico. MATERIALES Y MÉTODOS: Estudio transversal en personal de salud de hospitales públicos de referencia del Departamento de Alto Paraná, Paraguay. Se incluyeron 962 participantes, mediante muestreo no probabilístico de tipo consecutivo, aplicación de cuestionario y toma de muestras sanguíneas. Se buscaron anticuerpos por ensayo inmunocromatográfico para detección de IgM e IgG contra SARS- CoV-2 y por el método ELISA de captura de IgG específicos contra la proteína spike (SARS-CoV-2) y se evaluaron factores asociados a la seropositividad. RESULTADOS: La seroprevalencia global fue 36,5% (IC 95%: 33,4 - 39,5); 59,3% (n: 571) de los encuestados refirió haber tenido síntomas compatibles al COVID-19 entre el inicio de la pandemia y la fecha de toma de muestra, de estos 44% (n: 251) resultó seropositivo; 10,4% (n: 100) manifestó no haber tenido síntomas en el periodo estudiado, pero tuvo un resultado positivo. Los factores asociados a la seropositividad fueron: presencia de síntomas (p 90 días). CONCLUSIONES: Las características clínicas fueron mayormente asociadas con la seropositividad y la seropreva- lencia en los sintomáticos varió de acuerdo con el tiempo transcurrido desde el inicio de los síntomas y la serología.


BACKGROUND: Understanding the behavior of humoral response in COVID-19 continues to be a challenge to produce vaccines that provide long-lasting immunity. AIM: To describe the natural humoral response induced by SARS-CoV-2 among healthcare workers based on epidemiological and clinical profiles. METHODS: Cross-sectional study in healthcare workers from public hospitals in the Department of Alto Paraná, Paraguay, 962 participants were recruited through consecutive sampling, using a questionnaire and blood sampling. Antibodies were determined by immunochromatography assay for detection of IgM and IgG and by SARS-CoV-2 IgG anti-spike capture ELISA method and factors associated with seropositivity were evaluated. RESULTS: The overall seropositivity was 36.5% (95% CI: 33.4 - 39.5); 59.3% (n: 571) of respondents reported symptoms compatible with COVID-19 since the start of the pandemic and the date of blood draw, 44% (n: 251) of them tested positive; 10.4% (n: 100) who reported no history of symptoms tested positive. The factors associated with seropositivity were the presence of symptoms (p 90 days). CONCLUSIONS: Clinical characteristics were mostly associated with seropositivity and sero prevalence in symptomatic participants varied according to the time elapsed from the onset of symptoms to serology.

ABSTRACT

Background As the population ages, there has been a growing focus on the decline in fertility. Research has identified age and fertility history as the primary influencing factors. Nevertheless, there is a deficiency in fundamental data regarding the fertility status among different industries. Objective To investigate the fertility status and influencing factors among female workers aged 22-35 years in different industries. Methods From July 2020 to February 2021, a cross-sectional survey was conducted using a staged sampling approach. This survey specifically targeted 22-35-year-old married female workers with a history of pregnancy in industries such as education, healthcare, finance, and telecommunications, totaling 22903 participants. The survey encompassed industry, demographic characteristics, pregnancy history, time to pregnancy (TTP), and other influencing factors. The influencing factors of decline in fertility were identified by chi-square test and Cox proportional hazards regression. Subsequent industry-specific Cox proportional hazards regression models were used to compared fertility decline patterns across a spectrum of industries after selected influencing factors were adjusted. Results Among the 22903 respondents, 19194 valid questionnaires were collected, with a valid recovery rate of 83.8%. The cumulative pregnancy rates (CRP) of 1-6 months and 1-12 months for the 22-35-year-old female workers were 67.23% and 91.33% respectively. The multivariate analysis showed that region, age, education level, personal annual income, housework time, coping style, gravidity, parity, and spontaneous abortion were influencing factors of fertility decline (P<0.05). Female workers with ≥3 gravidities and ≥2 spontaneous abortions had a higher risk of fertility decline, with hazard ratios (HR) and associated 95% confidence interval (95%CI) of 0.633 (0.582, 0.688) and 0.785 (0.670, 0.921) respectively (P<0.01). Compared to the education industry, the healthcare and finance industries showed a higher risk of fertility decline, with HR (95%CI) values of 0.876 (0.834, 0.920) and 0.909 (0.866, 0.954), respectively (P<0.05). These two HR (95%CI) values remained statistically significant [0.899 (0.852, 0.948) and 0.882 (0.833, 0.934) respectively, P<0.05)] after further adjustment with nine influencing factors such as region and age. Conclusion Regions, age, education level, personal annual income, housework time, coping style, pregnancy and childbirth times, and natural abortion times are influencing factors of fertility decline in female workers. Compared to the education industry, the healthcare and finance industries have a higher risk of declining fertility.

ABSTRACT

ObjectiveTo investigate the current status and influencing factors of hand hygiene practices among primary healthcare workers, and to provide a reference for improving hand hygiene behavior in primary healthcare institutions. MethodsA self-designed questionnaire was used to conduct a survey among medical staff of seven community health service centers in Jiading District, Shanghai, using a cluster random sampling method. The data collected were subjected to descriptive statistics, reliability and validity tests, correlation analysis, and structural equation model fitting. ResultsA statistical difference in hand hygiene compliance was found among medical staff with varying occupational types and educational levels (P<0.05), and medical staff in clinical departments exhibited higher levels of hand hygiene compliance (P<0.05). In the health belief model, among the core variables, healthcare workers’ perceived benefits, perceived barriers, and self-efficacy had a direct impact on hand hygiene behavior, with direct effect values of 0.341, -0.152, and 0.234, respectively. Meanwhile, cues to action and perceived severity of COVID-19 infection indirectly affected hand hygiene behavior, with an indirect effect value of 0.066 and 0.062, respectively. ConclusionHealthcare workers generally exhibit a high degree of hand hygiene compliance, but there are variations in hand hygiene scores among healthcare workers with different characteristics. Enhancing healthcare worders’ perception of benefits, action cues, and self-efficacy while reducing perceived barriers can effectively improve their hand hygiene behavior.

ABSTRACT

Objective To analyze the micronucleus rate of radiation workers and to provide accurate occupational health monitoring basis in radiation workers exposed to low-level ionizing radiation for a long time. Methods The radiation group consisted of 353 radiation workers who had been exposed to ionizing radiation during work, while the control group consisted of 41 radiation workers who had not yet been exposed to ionizing radiation before work. The cytokinesis-block micronucleus method was used to determine the micronucleus rate. Results The average micronucleus rate in the radiation group was significantly higher than that in the control group (t = −2.95, P < 0.05). In the radiation group, the micronucleus rate gradually increased with age, and the difference was statistically significant (F = 8.36, P < 0.05). The micronucleus rates of workers with > 10 and > 30 years of service were significantly higher than those of workers with < 10 years of service (χ2 = −44.79, −60.47, P < 0.05). The micronucleus rate in females was significantly higher than that in males (t = 3.93, P < 0.05). The micronucleus rates in the diagnostic radiology group and the industrial detection group were significantly higher than that in the control group (t = 3.51, 3.65, P < 0.05). Conclusion The micronucleus rate has increased among the radiation workers exposed to low-level ionizing radiation for a long time. It is necessary to further strengthen occupational health monitoring and radiation protection education for radiation workers, especially the medical workers that constitute the largest population of radiation exposure workers.

ABSTRACT

Objective To understand the effects of long-term exposure to ionizing radiation on the health of radiation workers. Methods A total of 215 radiation workers were randomly selected and assigned to the exposure group and 197 non-radiation workers were assigned to the control group. The occupational health examination results of the two groups were compared and analyzed. Results The WBC count of the exposure group was lower than that of the control group (P<0.05), while the abnormality rates of ocular lens, ECG, liver function, and thyroid function were significantly higher in the exposure group than in the control group (P<0.05). In the exposure group, the abnormality rate of liver function was lower in females than in males, and the abnormality rate of hemoglobin level was higher in females than in males (P<0.01). The abnormality rate of ocular lens increased with age (P<0.01). The abnormality rate of hemoglobin level was different among different age groups (P<0.01). The abnormality rate of ocular lens increased with increasing years of service. The abnormality rates of RBC count and hemoglobin level in the general radiotherapy group were higher than those in the interventional radiotherapy group (P<0.01). Sex was the influencing factor for abnormal liver function (P<0.01). Conclusion Prolonged exposure to low doses of ionizing radiation can adversely affect the health of radiation workers in medical institutions.

ABSTRACT

Objective To analyze micronucleus abnormalities in the peripheral blood lymphocytes of industrial radiation workers and the influencing factors, and to provide a reference for radiation protection. Methods The occupational health monitoring data of 661 industrial radiation workers were collected from the occupational health examination system of Gansu Provincial Center for Disease Control and Prevention. The abnormalities in the micronucleus of peripheral blood lymphocytes were analyzed. The influencing factors were identified by logistic regression. Results The micronucleus abnormality rate was 6.05% for the 661 industrial radiation workers. There was no significant difference in micronucleus abnormality rate between sexes (P > 0.05). Comparison of age groups showed that the rate of micronucleus abnormality increased with age, and workers over 50 years of age has the highest rate of micronucleus abnormalities (17.81%); there was a significant difference between age groups (P < 0.05). There was a significant difference in micronucleus abnormality rate between occupational categories (P < 0.05). There was a significant difference in micronucleus abnormality rate between groups with different years of work (P < 0.05). Logistic regression analysis showed that age and years of work were the risk factors for micronucleus abnormality rate (P < 0.05); age was an independent risk factor for micronucleus abnormality rate (P < 0.05). Conclusion The effect of low-dose ionizing radiation on micronucleus abnormality rate of industrial radiation workers is related to age and working years. Attention should be paid to occupational health monitoring of radiation workers, especially those with advanced age.

ABSTRACT

Objective:To analyze the current status of physical composition in medical workers and the evaluation effects of each indicator on nutritional status.Methods:It was a cross-sectional study. A total of 313 medical workers from one hospital in Beijing were recruited from May 21st to June 22nd in 2021 for body composition measurement. Variance analysis was used to compare the age and gender distribution differences in total body fat, fat-free body weight, body fat percentage, skeletal muscle, protein, water, mineral, and basal metabolic rate indicators among the medical workers. Protein content, body fat percentage, and body mass index (BMI) were used to evaluate the nutritional status of medical workers, and the evaluation effects were analyzed too.Results:Of the 313 medical workers included in this study, there were 221 females and 92 males. In females, total body fat, fat-free body weight, skeletal muscle mass, and basal metabolic rate were all positively correlated with age ( F=19.823, 6.745, 6.561, 6.707) (all P<0.001). There was no significant differences in body composition indicators among male participants of different age groups (all P>0.05). The total body fat in female medical workers was significantly higher than that in males (17.58 kg vs 17.08 kg). Total water, protein, minerals, fat-free body weight, skeletal muscle mass, and basal metabolic rate were all significantly lower in female medical workers when compared with those in males [30.40 kg vs 41.78 kg, 8.07 kg vs 11.26 kg, 2.96 kg vs 3.88 kg, 41.43 kg vs 56.92 kg, 22.37 kg vs 31.98 kg, 1 264.86 kcal (1 kcal=4.184 kJ) vs 1 599.39 kcal] (all P<0.05). Among the medical workers, 190 cases (60.7%) had normal protein levels, 103 cases (32.9%) had protein deficiencies, and 20 cases (6.3%) had protein levels exceeding the standard. Additionally, 110 cases (35.1%) had normal body fat ratios, 193 cases (61.6%) had excessive body fat ratios, and 10 cases (3.2%) had insufficient body fat ratios. Concerning body mass index (BMI), 198 cases (63.2%) had normal BMI. Among them, 145 cases (73.2%) had normal body fat ratios, 53 cases (26.7%) had excessive body fat ratios, 108 cases (54.5%) had normal protein levels, 89 cases (44.9%) had insufficient protein levels, and 1 case (0.5%) had excessive protein levels. Furthermore, 103 cases (32.9%) had excessive BMI, with 20 cases (19.4%) having normal body fat ratios indicating the muscle/bone strength type, and 83 cases (80.6%) having normal protein levels indicating the muscular type. Lastly, 12 cases (3.8%) had insufficient BMI, including 6 cases (50.0%) with normal body fat ratios. Conclusion:There are significant gender differences in body composition distribution among healthcare workers. In females, total body fat, lean body mass, skeletal muscle, and basal metabolic rate are all correlated with age. Evaluating individual nutrition status based solely on BMI would underestimate the obesity rate. Individuals with low or high protein/muscle content should not be assessed using BMI.

ABSTRACT

Background It is a research hotspot to study the changes of metabolites and metabolic pathways in the process of coal worker's pneumoconiosis (CWP) by metabonomics and to explore its pathogenesis. Objective To study the change of metabolites in bronchoalveolar lavage fluid (BALF) of patients with CWP and explore the metabolic regulation mechanism of the disease. Methods Patients with CWP who met the national diagnostic criteria according to Diagnosis of occupational pneumoconiosis (GBZ 70-2015) and underwent massive whole lung lavage were selected as the case group, and patients with tracheostenosis who underwent bronchoscopy were selected as the control group. BALF samples were collected from the cases and the controls. After filtering out large particles and mucus, the supernatant was stored in a −80 ℃ refrigerator. The samples were detected and analyzed by liquid chromatography-mass spectrometry after adding extraction solution, cold bath ultrasonication, and high-speed centrifugation, and the metabolic profiles and related data of CWP patients were obtained. The differential metabolites related to the occurrence and development of CWP were screened by multiple statistical analysis; furthermore, we searched the Kyoto Encyclopedia of Genes and Genomes (KEGG) database for potential metabolic pathways involved in the progression. Results There was no significant difference in the general conditions of the subjects, such as weight, height, age, and length of service among the stage I group, the stage II group, the stage III group, and the control group (P˃0.05). When comparing the CWP stage I group with the control group, 48 differential metabolites were screened out, among which 14 were up-regulated and 34 were down-regulated. A total of 66 differential metabolites were screened out between the patients with CWP stage II and the controls, 14 up-regulated and 52 down-regulated differential metabolites. Compared with the control group, 63 differential metabolites were screened out in the patients with CWP stage III, including 11 up-regulated and 52 down-regulated differential metabolites. There were 36 differential metabolites that may be related to the occurrence of CWP, among which 11 differential metabolites were up-regulated, and 25 were down-regulated. Four significant differential metabolic pathways were identified through KEGG database query: linoleic acid metabolic pathway, alanine metabolic pathway, sphingolipid metabolic pathway, and glycerophospholipid metabolic pathway. Conclusion The metabolomic study of BALF show that there are 36 different metabolites in the occurrence and development of CWP, mainly associating with linoleic acid metabolism, alanine metabolism, sphingolipid metabolism, and glycerophospholipid metabolism pathways.

ABSTRACT

Background Shoemaking industry workers are prone to work-related musculoskeletal disorders (WMSDs) due to long-term awkward postures during the work process. There is little research on the prevalence and influencing factors of WMSDs in the knee region of this industry, and it should be taken seriously. Objective To estimate the prevalence of work-related knee pain among shoemaking workers and analyze the related influencing factors. Methods A total of 6982 shoemaking workers were selected from 26 shoemaking factories in Guangdong, Hubei, Fujian, Chongqing, Shandong, Zhejiang, and Jingxi by convenience sampling. Prevalence of work-related knee pain in past year, demographic characteristics, occupational related factors, and work posture were collected by a cross-sectional survey using the electronic version of Musculoskeletal Disorder Questionnaire. Logistic regression analysis was used to analyze the influencing factors that may lead to work-related knee pain. Results This survey collected 6982 valid questionnaires with a recovery rate of 98.3%. The prevalence of work-related knee pain of shoemaking workers in the past 12 months was 13.0% (908/6982). According to the results of logistic regression analysis, compared with workers with less than 5 years of service, workers with 5-10 years of service (OR=1.21, 95%CI: 1.02, 1.45) and more than 10 years (1.53, 95%CI: 1.27, 1.83) showed a higher risk of knee WMSDs; sometimes, often and very frequent (reference : rarely or never) long-term standing (OR=1.33, 95%CI: 1.08, 1.64; OR=2.67, 95%CI: 2.10, 3.39; OR=2.75, 95%CI: 2.08, 3.63) and sometimes, often and very frequent (reference: rarely or never) long-term squatting or kneeling (OR=1.80, 95%CI: 1.47, 2.21; OR=2.43, 95%CI: 1.58, 3.75; OR=3.22, 95%CI: 1.66, 6.24) increased the risk of knee pain: long-term bending (OR=1.59, 95%CI: 1.34, 1.89) and often repeated movement of lower limbs and ankles (OR=1.48, 95%CI: 1.25, 1.75) were also risk factors for knee WMSDs among shoemaking industry workers (P<0.05). Adequate rest time (OR=0.58, 95%CI: 0.49, 0.68) and able to stretch or change leg posture (OR=0.75, 95%CI: 0.64, 0.88) reduced the risk of knee WMSDs (P<0.05). Conclusion In the shoemaking industry, length of service and awkward postures are risk factors for knee pain. The shoemaking enterprises should ensure that workers have sufficient rest time, reduce long-term standing, squatting, kneeling, and bending postures, as well as lower limbs repetition in order to reduce the occurrence of knee WMSDs of workers.

ABSTRACT

Background Unhealthy lifestyles may constitute significant risk factors for dyslipidemia. However, limited studies focus on the association mentioned above among railway workers undertaking frequent shift work. Objective To understand the status of dyslipidemia and lifestyles among railway workers, and to investigate the association between the lifestyles of workers involved in different shift work schedules and dyslipidemia, aiming to provide a reference for the development of targeted intervention strategies against dyslipidemia in this occupational group. Methods The participants were selected from the in-service staff of a railway unit in 2021. A quota sampling approach was used to ensure the participation of at least 50% of employees from each department. Demographic and lifestyle information of the railway workers in 2021 was collected through self-administered questionnaires, while physiological and biochemical indicators were obtained through health examinations. Chi-square tests were employed to analyze the distribution of dyslipidemia among railway workers with different characteristics. Binary logistic regression was utilized to examine the associations between selected variables and dyslipidemia, and additive model was used to investigate the interaction between lifestyle and different shift work schedules on dyslipidemia. Results A total of 17392 railway workers were included in the study, and the total prevalence of dyslipidemia was 31.3%, with a higher prevalence reported among workers undertaking rotating night shifts (33.5%) and permanent night shifts (34.3%) than those with regular day work. The main adverse lifestyles among the railway workers were physical inactivity (59.6%), alcohol consumption (40.0%), and smoking (35.7%), and only 13.6% reported a healthy lifestyle. Furthermore, significant statistical differences in the prevalence of dyslipidemia were reported among workers with different lifestyles (P<0.01). After adjusting for confounding factors, smoking was a risk factor for dyslipidemia (OR=1.61, 95%CI: 1.48, 1.75), while highly active physical activity served as a protective factor against dyslipidemia (OR=0.79, 95%CI: 0.71, 0.88). In general, adopting a healthy lifestyle was associated with a decreased risk of dyslipidemia (OR=0.86, 95%CI: 0.77, 0.95). The stratified analyses based on different shift work schedules revealed a statistically significant association between smoking and dyslipidemia across various shift work occupational groups (P<0.001): regular day work, OR=1.62, 95%CI: 1.42, 1.84; rotating night shifts, OR=1.54, 95%CI: 1.35, 1.76; and permanent night shifts, OR=1.75, 95%CI: 1.40, 2.18. In regular day workers, highly active physical activity was associated with a reduced risk of dyslipidemia (OR=0.81, 95%CI: 0.69, 0.95). A similar association was observed among workers undertaking rotating night shifts (OR=0.78, 95%CI: 0.65, 0.94); furthermore, moderately active physical activity was also associated with a reduced risk of dyslipidemia in this occupational group (OR=0.85, 95%CI: 0.74, 0.97). There was no additive interaction between rotating night shifts and lifestyle with relative excess risk due to interaction (RERI), attributable proportion due to interaction (AP), and synergy index (S) of 0.18 (95%CI: −0.04, 0.41), 0.15 (95%CI: −0.04, 0.33), and 3.19 (95%CI: 0.09~110.44), respectively. There was also no additive interaction between permanent night shifts and lifestyle, with RERI, AP and S of −0.03 (95%CI: −0.43~0.37), −0.02 (95%CI: −0.35~0.31) and 0.90 (95%CI: 0.18~4.46). Further stratification of populations according to shift work schedules and lifestyles revealed that those who worked rotating night shifts and reported unhealthy lifestyles were more likely to present dyslipidemia than those who undertook regular day work and had healthy lifestyles (OR=1.27, 95%CI: 1.09, 1.48). Conclusion Railway workers present less optimistic lipid health status, and unhealthy lifestyles are prevalent among them. Those engaged in night shift work report a higher prevalence of dyslipidemia. Among workers with different shift schedules, smoking and physical inactivity are identified as the primary risk factors for dyslipidemia, and particular attention should be paid to the lipid health status of rotating night shift workers with poor lifestyles.

ABSTRACT

Background The development of railways has a long history, but there is limited research on the health of railway workers at home and abroad. China's high-speed railway development has attracted worldwide attention in recent years, and it is of great significance to study how to promote the health of this occupational population to ensure the safety of railway transportation. Objective To identify development trends and hotspots in the field of railway workers' health at home and abroad. Methods The research literature related to the health of railroad workers dated from January 1, 1973 to December 31, 2022 was searched using the China Knowledge Network Infrastructure (CNKI) and Web of Science Core Collection (WoS) databases. After screening and cleaning, the included literature was subjected to bibliometric analysis by applying CiteSpace 6.1R6 software to visualize and analyze literature co-citation, keyword emergence, and keyword timeline graphs, and by VOSviewer 1.6.19 to visualize and analyze country/region collaboration, keyword co-occurrence, and keyword clustering. Results During the period from 1973 until 2022, a total of 273 Chinese literature and 165 English literature were found to report studies related to the health of railway workers. The Chinese literature began to grow rapidly in 2009 and peaked in 2015, and the number of English literature published in a relatively flat state over the studied period. The country with the most papers indexed by Science Citation Index (SCI) was the United States (58 papers), which also presented the richest international collaborations. The document with the highest domestic citation frequency was published in the Chinese Journal of Mental Health in 1994, and the document with the highest SCI citation frequency was published in the American Journal of Epidemiology in 1994. The keyword co-occurrence analysis showed that the included Chinese literature mainly focused on health checkups, health management, hypertension, mental health, and chronic diseases and their prevalence; the included English literature focused on mortality, lung cancer, epidemiology, and diesel engine exhaust and its exposure. The analysis of emergent words showed that health management, frontline workers, and occupational stress were the topics of interest in Chinese literature in the last five years, while occupational stress, diesel exhaust emissions, and noise exposure were the topics of interest in English literature in the last ten years. The results of the timeline graph analysis suggested that the recent research directions in Chinese literature were health intervention, humanistic care, staff canteens, etc. There were few English-language articles related to this area after 2010. Conclusion The research hotspots of railroad practitioners' health will keep changing with the development of high-speed railways in countries around the world. The outstanding rise of Chinese literature issued in the last decade has been in striking contrast to the slow progress and decreasing of English literature. The Chinese literature has gradually expanded the hotspots from chronic diseases to health management, occupational stress, and sleep disorders.

ABSTRACT

@#Introduction: This study aimed to evaluate town service personnel’s knowledge, attitudes, and practices (KAP) regarding leptospirosis prevention and the influencing factors to its practice. Methods: A cross-sectional study was conducted in Kuching, Malaysia, involving town service workers using a self-administered validated questionnaire comprising sociodemographic and KAP information. The eligibility criteria included 18 years old and above and having worked for more than six months. The KAP was determined using descriptive analysis, and associations were identified using logistic regression analysis. Results: About 189 town service workers responded, giving a response rate of 87.5%, and a majority of them were Bumiputera Sarawak, with a mean age of 38.6 (±11.00) years old. The mean duration of employment was 9.3 (±6.99) years. About 88.9% had good knowledge of leptospirosis. Meanwhile, 85.2% and 79.9% had satisfactory attitudes and good practices. The knowledge on the aetiology of leptospirosis ranged from 25% to 94%. No significant association was found between the knowledge score and income with the practice score. The attitude score (AOR 1.161; 95% CI = 1.090, 1.238; p = 0.000) and working experience (AOR 1.174; 95% CI = 1.023, 1.346; p = 0.022) were found to be significantly associated with their practice score. Conclusion: Most town service workers have good knowledge and practice regarding leptospirosis prevention. Workers with good attitudes demonstrate good practising habits toward leptospirosis prevention. Awareness and activities related to disease prevention should be encouraged to ensure the continuity of a positive attitude.

ABSTRACT

Objective To investigate the effects of prolonged low-dose neutron-γ radiation on peripheral blood lymphocytes of logging workers. Methods The health information of workers in a logging company was collected by on-site blood sample collection and questionnaire survey. Individual doses of γ and neutron radiation were recorded using LiF elements and CR-39, respectively. Lymphocyte count in peripheral blood was measured by blood cytometer. Cell cycle and cyclins were detected by flow cytometry. Results The annual dose of some logging workers exceeded 5 mSv. Lymphocyte counts showed a difference of 15% between the group exposed to the lowest annual dose of 0–1 mSv (mean: 2.45 × 109/L) and the group exposed to the highest annual dose of 5–25 mSv (mean: 2.08 × 109/L). In comparison to pre-shift workers, logging workers exhibited a G1-phase arrest in the lymphocyte cycle, along with increased expression of cyclins p21 and CDK2. Conclusion Prolonged exposure to low-dose neutron-γ radiation leads to reduced lymphocyte counts as well as changes in lymphocyte cycle and cyclin expression.

ABSTRACT

ObjectiveTo describe the epidemic characteristics of COVID-19 after policy adjustment from “Category B notifiable disease with category A management” to “Category B notifiable disease with category B management”, and to explore the protective effect of previous infection with SARS-CoV-2 on common symptoms of reinfection. MethodsHealthcare workers infected with SARS-CoV-2 in a grade A tertiary hospital in Shanghai were included in the study from December 4, 2022 to January 11, 2023. Data on demographic characteristics, clinical symptoms, medical history, and COVID-19 vaccination history were collected. We determined the epidemiological curve and characteristics, and then compared the difference in the severity of clinical symptoms between primary and reinfection subjects. ResultsA total of 2 704 cases were included in the study, of which 45 had reinfection, 605 (22.4%)were males, 608 (22.5%)were doctors, 1 275 (47.2%) were nurses, and 2 351 (86.9%) received ≥3 doses of COVID-19 vaccination. The average age of these healthcare workers was (34.9±9.1) years old. The number of cases with mild/moderate illness, asymptomatic infection, fever, headache, dry cough, expectoration, and chest tightness were 2 704 (100.0%), 92 (3.4%), 2 385 (88.2%), 2 066 (76.4%), 1 642 (60.7%), 1 807 (66.8%), and 439 (16.2%), respectively. Reinfection was a protective factor for fever (OR=0.161, P<0.001), headache (OR=0.320, P<0.001), and peak body temperature (β=-0.446, P<0.001). ConclusionFollowing the COVID-19 policy adjustment as a category B notifiable disease, healthcare workers at a grade A tertiary hospital in Shanghai predominantly experiences mild to moderate COVID-19 symptoms. Reinfection results in milder clinical manifestations, with a lower proportion of being asymptomatic.

ABSTRACT

ObjectiveTo investigate the levels of serum antibodies against novel coronavirus (SARS-CoV-2) in healthcare workers after one month of natural infection, to explore the influencing factors and their correlations with the levels of antibodies, and to provide reference for strengthening the protection of healthcare workers and preventive intervention in Pudong New Area in Shanghai. MethodsVenous blood samples were collected from 1 102 medical staff in Pudong hospitals one month after infection. The serum levels of new coronavirus specific antibodies IgM, IgG and neutralizing antibodies were detected by chemiluminescent immunoassay. The information of gender, age, position, infection severity, vaccination, basic diseases and use of immunosuppressants were obtained by questionnaire to explore the influencing factors and their correlation with the antibody level. ResultsOne month after natural infection, 99.00% (1 091/1 102) of the subjects were found to be positive for IgG antibody against the new coronavirus, 17.79% (196/1 102) of the subjects were IgM antibody positive, and 99.00% (1 091/1 102) of the samples were positive for the neutralizing antibody. The level of antibody might be influenced by the severity of infection, the time of the last dose of vaccination, and the long-term use of immunosuppressants. The more severe the disease, the stronger the neutralizing antibody response. The antibody level in the people who received the final dose of vaccine within 6 months was higher than that of the people who received the vaccine 6 months ago, and the difference was statistically significant. The antibody levels were low in the subjects who received long-term immunosuppressants. ConclusionThe specific IgM, IgG and neutralizing antibody were found, one month after infection, in the medical workers in Pudong New Area, Shanghai, and the antibody titers were high, which had a good protective effect. The antibody level of the people who were vaccinated within 6 months was higher, it is recommended that people who receive the last vacination more than 6 months should be re-vaccinated with the booster vaccine, to improve the autoimmunity against the novel coronavirus.

ABSTRACT

Background Multi-slice spiral computerized tomography (MSCT) can be used as an auxiliary diagnosis of chest radiography in diagnosis of pneumoconiosis, but there are few studies on the correlations between interstitial images and stage classification of coal workers' pneumoconiosis in the existing literature. Objective To present MSCT imaging manifestations and distribution characteristics of coal workers' pneumoconiosis and complications, evaluate correlations between coal workers' pneumoconiosis stages and pulmonary interstitial lesions, and provide a reliable imaging diagnosis basis for pneumoconiosis interstitial lesions. Methods From June 2022 to June 2023, a total of 1002 patients with coal workers' pneumoconiosis confirmed by the pneumoconiosis diagnostic and identification group in the Department of Occupational Diseases of the Emergency General Hospital were enrolled. MSCT was used to observe the abnormal imaging manifestations of the lungs of coal workers' pneumoconiosis patients and the diseases of pulmonary fibrosis related to their own diseases (thickening of the interlobular septum, bronchial perivascular interstitial mass thickening, parenchymal banding, subpleural line, intralobular interstitial thickening, honeycomb, and subpleural interstitial thickening), the occurrence of coal workers' pneumoconiosis and complications (old tuberculosis, active tuberculosis, pneumonia, atelectasis, lung cancer, bronchiectasis), and the density, size, and location of pneumoconiosis nodules. Imaging data were analyzed and statistically processed. Results All 1002 patients were male, with an average age of (60.71±6.87) years and an average dust exposure time of (23.01±7.80) years. Among them, there were 470 patients with stage I, 422 patients with stage II, and 110 patients with stage III. There were significant differences in the distribution of thickening of the interlobular septum, bronchial perivascular interstitial mass thickening, parenchymal banding, intralobular interstitial thickening, subpleural interstitial thickening, and honeycomb across different stages (P<0.05). Statistically significant differences in p, q, and r subsets of round nodules were found in patients with pneumoconiosis at different stages (P<0.05). Observed nodule types included solid nodules, pure ground-glass shadow nodules, and partial solid nodules. There were statistically significant differences in pulmonary tuberculosis and bronchiectasis among different stages of coal workers' pneumoconiosis (P<0.05). There were statistically significant differences in interstitial shadows and patches combined with interstitial shadows among different stages of pneumoconiosis complicated with pneumonia (P<0.05). Conclusion MSCT provides images of the progression of coal workers' pneumoconiosis and have a certain relationship with the stages of coal workers' pneumoconiosis, which is conducive to the formulation of reasonable treatment plans in the early clinical stage. Therefore, in the diagnosis and treatment of pneumoconiosis, a great attention should be paid to the imaging technology of chest computerized tomography, especially the use of MSCT examination.
