Suggested Work Modifications for Patients with Environmental and Occupational Risk Factors in Hidradenitis Suppurativa

Hidradenitis suppurativa (HS) is a chronic, inflammatory skin condition characterized by painful nodules, abscesses, and scarring, primarily affecting areas rich in apocrine glands. Environmental and occupational risk factors, including prolonged exposure to heat, friction, and certain chemicals, have been identified as exacerbating conditions for HS. Yet, there remains a lack of tailored recommendations for modifying work environments to alleviate these triggers. This review presents novel suggestions for work modifications to reduce HS flare-ups, such as implementing breathable, friction-reducing workwear, ergonomic adjustments to minimize pressure on affected areas, and introducing low-irritant hygiene protocols in workplaces with chemical exposure. These recommendations are grounded in emerging evidence linking specific occupational exposures to the exacerbation of HS symptoms. The novelty of this approach lies in its proactive stance, shifting from reactive management of HS symptoms to preventative environmental modifications. Future studies should explore the long-term efficacy of these modifications and investigate the potential for personalized work environment adjustments based on individual patient profiles. Targeted workplace interventions may significantly improve the quality of life for HS patients, highlighting the need for multidisciplinary collaboration between dermatologists, occupational health specialists, and employers.

Nursing managers should pay attention to the work environment of ICU nurses, rationally allocate manpower, and improve the status of psychological resilience of nurses, so as to improve their quality of work life.

What Is the Role of Work-Related Factors in Self-Reported Health Inequalities among Employed Individuals? A Longitudinal Study in Luxembourg

Objectives: We measured health inequalities among employed Luxembourg residents over time and the socio-economic and work-related determinants. Design and Setting: Longitudinal data were obtained from the Socio-economic Liewen zu Lëtzebuerg/European Union Survey on Income and Living Conditions, which has been conducted each year since 2003 in Luxembourg. Participants: Participants comprised 727 Luxembourg residents (58% men), aged between 21 and 55 years in 2003, who were employed between 2003 and 2012. Primary and Secondary Outcomes Measured: The variable of interest was self-reported health. We used transition indicators on work-related factors to consider changes that individuals may have experienced in their job over this period. Results: People who moved from a part-time to a full-time contract (odds ratio (OR): 5.52, confidence interval (CI): 1.55 - 19.73), and those who moved from the 3rd or 4th quartile of earnings to the 1st or 2nd quartile (OR: 2.48, CI: 1.02 - 6.05) between 2003 and 2012, had a higher risk of being in poor health in 2012. The risk of deterioration in self-reported health in 2012 among people who were healthy in 2003 was associated with the type of contract, economic activity, and occupation. Conclusion: Health inequalities occur among employed people in Luxembourg. Their importance varies according to work-related characteristics and economic activity. Our findings showed that declined health status was associated with contract type, profession, and economic activity. This suggests that measures should be taken to maintain good health for people working in these specific occupations or economic sectors (e.g. preventive action, reduction of risk exposure, change of occupation in the same company, and so on).

Prevalence of Occupational Stress and Related Risk Factors among Nurses Working in ASEER Region

Background: Over the last century, stress as an interdisciplinary concept has become an area of great interest and has been researched extensively. Although the earliest studies on stress were mostly physiological, psychological models of stress have been developed and established a link between stressors and illness in his model of general adaptation syndrome. Objective: To investigate prevalence and factors associated with occupational stress among nurses working Asser region Hospital. The study included nurses at different age groups working at different departments with assessment of any sources of stress. Methodology: A descriptive cross-sectional study was conducted targeting nurses in the main hospitals in the Asser region, Southern Saudi Arabia. A total of the study samples of 217 nurses were required to estimate the expected average stress rate among nurses. A self-administered pre-structured questionnaire used for data collection. Results: Nurses’ ages ranged 21 to 55 years old with mean age of 30.9 ± 11.7 years old. Majority of the nurses were females 175 (80.6%). The highest mean score (more stress) was reported by nurses in relation to the following stress factors;working very hard (4.3 ± 0.9), followed by being under pressure to work long hours (4.2 ± 0.9), the opportunity given to do something is not real and enough (4.2 ± 1.0). The findings showed a significant relationship between nurses’ stress level, their personal and work-related characteristics (P = 0.001). Recommendations: Interventional programs to detect and alleviate sources and effects of occupational stress should be developed including more training regarding coping strategies, nurses’ support, and better work condition.

Role of hippocampal dentate gyrus neurons in the protective effects of heat shock factor 1 on working memory

Increasing evidence suggests that heat shock factor 1 exerts endogenous protective effects on working memory under conditions of chronic psychological stress. However, the precise underlying mechanisms remain poorly understood. This study examined the protective factors affecting working memory in heat shock transcription factor 1 gene knockout mice. The results indicated that the number of correct T maze alternations decreased following mild chronic psychological stress in knockout mice. This change was accompanied by a decrease in neurogenesis and an increase in neuronal apoptosis in the hippocampal dentate gyrus. The number of correct T maze alternations was positively correlated with neurogenesis in hippocampal dentate gyrus, and negatively correlated with neuronal apoptosis. In wild type mice, no significant difference was detected in the number of correct T maze alternations or neuronal apoptosis in hippocampal dentate gyrus. These results indicate that the heat shock factor 1 gene has an endogenous protective role in working memory during mild chronic psychological stress associated with dentate gyrus neuronal apoptosis Moreover, dentate gyrus neurogenesis appears to participate in the protective mechanism.

How Work Organization Affects the Prevalence of WMSDs: A Case-control Study

Objective In this study, we aimed at exploring the association between work-related musculoskeletal disorders（WMSDs） and work organization based on a case-control study. Methods A total of 1938 workers who claimed to suffer from WMSDs were selected from Beijing, Henan, Hubei, and the Guangdong province. The control group consisted of 2009 workers employed in similar industries without severe disease or musculoskeletal discomforts. We used a modified version of the questionnaire developed by the NMQ and the DMQ to investigate individual and work-related factors. Results A total of 13 variables（P〈0.1） were selected by the chi-square test and finally, 7 variables entered into the equation, with 6 variables reaching statistical significance（P〈0.05）. The odds ratios（OR） of ＇work changing with season＇ and ＇sufficient rest time＇ did not reach 1（0.749 and 0.441, respectively）. In addition, ＇sufficient rest time＇ seemed to be the stronger protective factor according to its higher standardized coefficient. And ＇repetitive work every minute＇, ＇constantly repetitive work＇（every day）, ＇shortage of site personnel＇, and ＇often switching shifts with others＇ seemed to be the risk factors. Conclusion Work organization may have comprehensive effects on the occurrence of WMSDs. This pattern of associations suggests that further investigation into the mechanism of how work organization affects the prevalence of WMSDs is required.

Energy efficiency evaluation based on DEA integrated factor analysis in ethylene production

Energy efficiency evaluation plays an important role in energy efficiency improvement of the ethylene production. It is observed from the actual production data that the ethylene production energy efficiency often varies with the complex production working conditions. In the favored methods for energy efficiency evaluation,DEA models may show poor resolution when directly used to evaluate the efficiency values. Therefore, a new energy efficiency evaluation method for ethylene production is proposed based on DEA integrated factor analysis with respect to operation classification. Three key factors, including raw material composition, cracking depth and load rate, are taken into account in determining the production working conditions by means of k-means algorithm. Based on the multi-working conditions mode the energy efficiency evaluation of the ethylene production is made by using DEA model, where the most related energy data are screened by factor analysis.Furthermore, the supporting decision of energy efficiency improvement is provided to the operators. The accuracy and effectiveness of the proposed method are illustrated by applying in a practical ethylene production,which gives more effective energy efficiency evaluation in the complicated working conditions of ethylene production with declined dimension of input indicators.

A Fast Multi-tasking Solution: NMF-Theoretic Co-clustering for Gear Fault Diagnosis under Variable Working Conditions

Most gear fault diagnosis(GFD)approaches su er from ine ciency when facing with multiple varying working conditions at the same time.In this paper,a non-negative matrix factorization(NMF)-theoretic co-clustering strategy is proposed specially to classify more than one task at the same time using the high dimension matrix,aiming to o er a fast multi-tasking solution.The short-time Fourier transform(STFT)is first used to obtain the time-frequency features from the gear vibration signal.Then,the optimal clustering numbers are estimated using the Bayesian information criterion(BIC)theory,which possesses the simultaneous assessment capability,compared with traditional validity indexes.Subsequently,the classical/modified NMF-based co-clustering methods are carried out to obtain the classification results in both row and column tasks.Finally,the parameters involved in BIC and NMF algorithms are determined using the gradient ascent(GA)strategy in order to achieve reliable diagnostic results.The Spectra Quest’s Drivetrain Dynamics Simulator gear data sets were analyzed to verify the e ectiveness of the proposed approach.

Cancer in Women and Its Relation to Work Systematic Review

Nowadays, cancer is one of the main worldwide causes of death and an increasing issue in public health. In the European Union, it is the first work-related cause of death. Studies about occupational risk exposure are a useful field of investigation to determine cancerous elements;special attention is paid to the relationship between cancer and work in women, who must constantly adapt to the working market and the new working fields, with their diverse degrees of exposure to risks. This revision has reviewed the bibliography gathered in Medline related to breast cancer, cervix cancer, uterus cancer, and ovarian cancer, along with their relationship with different work-related risks and types of working roles. The results have shown enough scientific evidence to suspect that work related exposition could be a plausible cause of these gynaecological cancers. Therefore, we want to stress the need of enhancing the coordinated investigation between all the medical specialties involved, and to encourage the spread of the necessary knowledge to manage and prevent them.

Promoting Clinician Well-Being and Patient Safety Using Human Factors Science: Reducing Unnecessary Occupational Stress

Our healthcare delivery system has accumulated complexity of payment, regulation systems, expectations and requirements. Often these are not designed to align with clinical thinking process flow of patient care. As a result, clinicians are utilizing enormous mental (cognitive) resource to comply with these complexities, over and above the baseline mental effort required to give good care to the patient. Recent studies suggest a significant number of physicians, advanced practice providers and nurses no longer want to stay in healthcare due to difficult work expectations and conditions that have become unreasonable. Technology has benefitted healthcare delivery, but also is a conduit of many expectations that have been grafted upon clinician workloads, exceeding the resources provided to accomplish them. Cognitive load is a measure of mental effort and is divided into Intrinsic, Germane and Extraneous Cognitive Load. Extraneous Cognitive Load (ECL) is what is not necessary and can be removed by better design. High cognitive load is associated with increased risk of both medical error and clinician burnout. Chronic high level occupational stress occurs from dealing with this job/resource imbalance and is showing serious personal health impact upon clinicians and the quality of the work they can provide for patients. Since organizational systems have become more complex, leadership methods, clinician wellbeing and patient safety efforts need to adjust to adapt and succeed. Safety efforts have tended to predominantly follow methods of a few decades ago with predominant focus upon how things go wrong (Safety I) but are now being encouraged to include more of the study of how things go right (Safety II). Human Factors/Ergonomics (HFE) science has been used in many industries to preserve worker wellbeing and improve system performance. Patient safety is a product of good system performance. HFE science helps inform mechanisms behind Safety I and II approach. HFE concepts augment existing burnout and safety interventions by providing a conceptual roadmap to follow that can inform how to improve the multiple human/technology, human/system, and human/work environment interfaces that comprise healthcare delivery. Healthcare leaders, by their influence over culture, resource allocation, and implementation of requirements and workflows are uniquely poised to be effective mitigators of the conditions leading to clinician burnout and latent medical error. Basic knowledge of HFE science is a strategic advantage to leaders and individuals tasked with achieving quality of care, controlling costs, and improving the experiences of receiving and providing care.
