Background Shoulder and neck pain is a highly prevalent musculoskeletal disorder. Different factors have been associated with it; among these factors some common are the use of a computer and smartphones without a break, sitting in an uncomfortable position. It has been reported that the prevalence of neck pain among smartphone users ranges from 20.0%-73%. This study will evaluate the prevalence of neck pain among smartphone users and the risk factors associated with it at the University of Balochistan Quetta Pakistan. Method This cross-sectional study was conducted from September to October 2022 at the University of Balochistan Quetta to find out the prevalence of neck pain and it risk factors. Data were collected randomly by distributing 500 questionnaires among the students irrespective of age, gender, department, and year of study. Data were analyzed using SPSS Version 23. Continuous variables were presented as mean ± SD, and categorical variables as frequencies and percentages. Univariate and multivariate binary logistic regression analysis were used to find out the risk factors associated with neck pain and a p-value <0.05 was considered significant. Results The results revealed that the prevalence of neck pain was 73%. In MVBLR analysis, male gender (OR=0.360, p-value=0.000), students in 4th year (OR=3.281, p-value=0.002), Left handed (OR=0.395, p-value=0.002), the habit of physical exercise (OR=0.594, p-value=0.032), number of social media used in a day (OR=2.414, p-value=0.039), use of other electronic devices (OR=1.858, p-value=0.010), style of holding (OR=3.289, p-value=0.008) and posture adopted during smartphones use (OR=0.614, p-value=0.050) had a significant association with the neck pain during smartphone use among university students. Conclusion In the current study high number of study, participants reported neck pain. Female gender, students in 4th year, left-handed, the habit of physical exercise, use of five or more social media applications, use of other electronic devices, and posture adopted on laying back were the risk factors associated with neck pain.

Reducing musculoskeletal disorders in iron ore mine operators: A fuzzy-based intervention approach.

This study focuses on evaluating the exposure to whole-body vibration (WBV) and association of musculoskeletal disorders (MSDs) with various risk factors among dumper operators in the mining industry. Despite the issue's significance, prior research has been limited. The study introduces a novel fuzzy-based approach for identifying, selecting, and prioritizing safety measures to mitigate MSD risks. Data collection comprised face-to-face interviews, anthropometric measurements, Rapid Upper Limb Assessment (RULA) scoring for posture assessment, and the Nordic Musculoskeletal questionnaire for assessment of MSD prevalence. Multiple linear and logistic regression models were used to analyse the contributing risk factors to MSDs and WBV exposure. These risk factors formed the basis for a practical approach to select appropriate safety measures based on fuzzy based aggregation method of expert's judgment aimed at mitigating the risk of MSDs. The results revealed that the risk factors such as poor work posture, WBV exposure and poor seat design were significantly associated with neck (adjusted odds ratio aOR = 4.81), upper limb and shoulder (aOR = 3.28), upper back (aOR = 5.09), and lower back pain (aOR = 3.67) at p < 0.05. Using these factors to formulate safety measures to reduce MSD risk, the minimization of sharp turns and abrupt changes in elevation in designing the haul roads, scheduled maintenance practices, and ergonomic seat design were found as important safety measures in this study. Our unique methodological approach in occupational health research could be highly beneficial for tailoring safety measures at the unit level with minimal effort.

Metalloproteins as risk factors for osteoarthritis: improving and understanding causal estimates using Mendelian randomization.

Osteoarthritis (OA) is one of the most prevalent musculoskeletal disorders and a primary cause of pain and disability among the elderly population. Research on the relationship between metalloproteins (MPs) and OA is limited, and causality remains unclear. Our objective is to utilize Mendelian randomization (MR) to explore the possible causal relationship between MPs and OA. The data on MPs were derived from a Genome-Wide Association Study (GWAS) analysis involving 3301 samples. The GWAS data for OA were obtained from an analysis involving 462,933 European individuals. In this study, a variety of two-sample Mendelian randomization methods (two-sample MR) to evaluate the causal effect of MPs on OA, including inverse variance weighted method (IVW), MR-Egger method, weighted median method (WM), simple mode, weight mode, and Wald ratio. The primary MR analysis using the IVW method reveals a significant negative correlation between Metallothionein-1F (MT-1F), zinc finger protein 134 (ZNF134), calcium/calmodulin-dependent protein kinase type 1D (CAMK1D), and EF-hand calcium-binding domain-containing protein 14 (EFCAB14) with the occurrence of osteoarthritis (OA) (p value < 0.05). However, no causal relationship was observed in the opposite direction between these MPs and OA. Notably, even in combined models accounting for confounding factors, the negative association between these four MPs and OA remained significant. Sensitivity analysis demonstrated no evidence of horizontal pleiotropy or heterogeneity, and leave-one-out analysis confirmed the robustness of the results. In this study, we have established a conspicuous association between four distinct MPs and OA. This discovery augments our understanding of potential avenues for the diagnosis and treatment of this condition. Key Points • The MR method was employed to assess the relationship between MPs and OA. • A total of four types of MPs have demonstrated inhibitory effects on the occurrence of OA.

Physical and Environmental Work Exposures and Prevalence of Musculoskeletal Disorders in Beekeepers: A Descriptive Study

Purpose: Beekeepers are at risk of musculoskeletal disorders while working, though research is scarce in this field. This study assessed beekeepers' physical and environmental occupational exposure and the prevalence of musculoskeletal disorders. Material and Methods: The study was conducted with 123 male individuals who had been actively beekeeping for a minimum of one year. Beekeepers were administered a survey that included demographic and occupational questions. Beekeepers responded to the Nordic Musculoskeletal Questionnaire and questions related to beekeeping activity from the Quick Exposure Check. Results: The mean age of the beekeepers was 45.4±12.3 years. The present study revealed that migratory beekeepers encountered a greater number of demanding circumstances in comparison to stationary beekeepers (p

Palmitic acid induces lipid droplet accumulation and senescence in nucleus pulposus cells via ER-stress pathway

Intervertebral disc degeneration (IDD) is a highly prevalent musculoskeletal disorder affecting millions of adults worldwide, but a poor understanding of its pathogenesis has limited the effectiveness of therapy. In the current study, we integrated untargeted LC/MS metabolomics and magnetic resonance spectroscopy data to investigate metabolic profile alterations during IDD. Combined with validation via a large-cohort analysis, we found excessive lipid droplet accumulation in the nucleus pulposus cells of advanced-stage IDD samples. We also found abnormal palmitic acid (PA) accumulation in IDD nucleus pulposus cells, and PA exposure resulted in lipid droplet accumulation and cell senescence in an endoplasmic reticulum stress-dependent manner. Complementary transcriptome and proteome profiles enabled us to identify solute carrier transporter (SLC) 43A3 involvement in the regulation of the intracellular PA level. SLC43A3 was expressed at low levels and negatively correlated with intracellular lipid content in IDD nucleus pulposus cells. Overexpression of SLC43A3 significantly alleviated PA-induced endoplasmic reticulum stress, lipid droplet accumulation and cell senescence by inhibiting PA uptake. This work provides novel integration analysis-based insight into the metabolic profile alterations in IDD and further reveals new therapeutic targets for IDD treatment.

Evaluating the Effectiveness of a Training on Ergonomic Risks of Measuring Blood Pressure.

Background: Musculoskeletal disorders (MSDs) occur as a result of long-term exposure to inappropriate working postures and repetitive use of body postures, leading to harmful consequences for patients, employees, and employers. Evaluating distinct working postures can contribute to effective interventions. Purpose: The aim of this study was to determine ergonomic risks of MSDs during repeated blood pressure measurement processes and to evaluate the effectiveness of a training on this topic. Methods: A pretest/posttest quasi-experimental design studied 64 nurses in a training and research hospital in Turkey. Participants were evaluated for the prevalence and risk of MSDs using the Nordic Musculoskeletal Questionnaire Extended Version and the Rapid Entire Body Assessment (REBA) Checklist, and by photographing them performing the procedure. Nurses with high risk for MSDs received an ergonomics training program and were followed up twice in 3 months. Results: Reduction in prevalence of MSDs in neck, shoulder, and hip/thigh areas, and in mean REBA scores after the training were statistically significant. Conclusion: Nurses should be trained about correct posture for specific high-risk activities that may cause MSDs, and offered exercise programs that support the musculoskeletal system.

Patterns of Musculoskeletal Disorders among Staff Nurses in the Emergency Department in Saudi Arabia: A Cross-sectional Study

Background: The physically demanding and high-stress environment of Emergency Departments (EDs) significantly contributes to the heightened risk of musculoskeletal disorders (MSDs) among ED nurses. Despite this known association, there is a lack of comprehensive understanding of the prevalence rates and contributing factors within ED settings in Saudi Arabia, necessitating further investigation.Purpose: This study delves into the prevalence and potential predictors of MSDs among nurses in this critical healthcare setting.Methods: A cross-sectional survey was conducted in March 2023 using convenience sampling of 177 ED nurses across 16 public hospitals in Hail, Saudi Arabia. The Nordic Musculoskeletal Questionnaire was employed, with SPSS analyses covering frequency and percentage of pain prevalence via cross-tabulation, and logistic regression to identify risk factors.Results: Over the past year, 68.9% of participants reported lower back pain affecting normal activities in 55.4% of cases. Neck pain was more likely in individuals aged 20-29 and former smokers accounting for 47.6% of the variance (p=0.001). Shorter shifts under 8 hours reduced neck pain risk, whereas a schedule with 50% of night shifts heightened the risk, contributing to 28.4% of the variance (p=0.001). Nurses aged 40-49 and those with significant childcare duties faced higher shoulder pain risk (p=0.024), and adult caregiving duties was linked to upper back pain explaining 40.6% of the variance (p=0.017). No significant links were found for other musculoskeletal pains.Conclusion: The study reveals a significant prevalence of MSDs among the evaluated ED nurses, significantly influenced by specific demographic and work-related factors. Addressing these through ergonomic interventions, optimal scheduling, and wellness programs is crucial for nurse well-being and patient care. Future research should focus on creating holistic wellness programs that support nurses musculoskeletal health.

Occurrence of musculoskeletal disorders, burnout, and psychological suffering in Brazilian nursing workers: A cross-sectional study.

Musculoskeletal disorders (MSDs) pose a pervasive concern among nursing professionals due to the high physical workload. Simultaneously, the complex relationship between MSDs and mental health outcomes in this population remains an area of significant interest and importance. This study aimed to investigate the occurrence of MSDs and their relationships with burnout and psychological suffering within the nursing workforce. A cross-sectional study was conducted in 2020 involving 291 nursing professionals in Brazil. Standardized questionnaires were employed to gather information on MSDs, mental health outcomes, and pertinent work-related factors. Robust statistical analyses were conducted to ascertain the prevalence of MSDs, establish associations between MSDs and mental health outcomes, and delineate the influence of work-related factors on these associations. Statistical analysis was performed using the R software. The study revealed a significant prevalence of musculoskeletal injuries (MSIs) among nursing workers, focusing on regions that include the lower back, upper back, neck, and shoulders. Individuals with MSIs in the lower back showed a marked increase in emotional exhaustion (p = 0.02), as did those with MSIs in the upper back (p <0.01) and depersonalization (p = 0.07). On the other hand, nursing professionals who reported MSIs in the neck and shoulders had considerably higher scores in emotional exhaustion (p <0.01 and p = 0.01, respectively) and depersonalization (p = 0.05 and p = 0.05, respectively). However, no significant correlations emerged between MSIs and depression or work-related factors. This study highlights the urgency of implementing proactive measures to prevent and manage MSDs within the nursing profession. Moreover, it emphasizes the critical need to enhance working conditions and provide robust support mechanisms to safeguard the mental health of nursing professionals.Open AccessOpen Access.

Effects of different treatments on pain, functional disability, position sense and range of motion in elite bodybuilders with chronic low back pain

Back pain is one of the major global challenges and is one of the most prevalent musculoskeletal disorders occurring in 80% of people at least once in their lifetime. Therefore, the need to find appropriate treatment methods for this issue is very important. The objective is to examine the short-term and acute effects of a treatment session with dry needling, massage therapy, stretching exercises and Kinesio tape on pain, functional disability, position sense and range of motion in elite bodybuilders with non-specific chronic low back pain. The sample of this quasi-experimental study consisted of 48 bodybuilders with non-specific chronic low back pain (all male, mean age = 25.96 ± 2.18 years; mean weight = 74.45 ± 4.51 kg; mean height = 173.88 ± 3.74 cm; mean BMI = 24.60 ± 0.74 kg/m2) who randomly were placed in 4 dry needling, massage therapy, stretching exercises and Kinesio tape groups. The duration of each intervention was 30 min. The dependent variables in this study included the massage range of motion, position sense tests and visual pain scale that were taken separately from each subject in pretest, posttest (acute effect) and follow-up test (72 h after posttest; short-term effect). The results of a 4 (groups) × 3 (time) the mixed ANOVAs showed that pain in the short-term phase was significantly lower in the dry needling group than in the stretching and massage groups (P < 0.05). Also in the acute effect phase, the flexion range of motion was significantly lower in the dry needling group than in the massage group (P < 0.05). Furthermore, the two groups of stretching and massage exercises showed significantly greater range of motion (P < 0.05). Other comparisons were not significant (P > 0.05). The findings of the study showed that both massage and stretching treatment have higher acute effects, while dry needling treatment was more effective in follow up. On the other hand, these findings show that these treatment methods can have immediate and lasting positive effects in improving the performance in elite bodybuilders with non-specific chronic low back pain.

Downside of Helping Professions: A Comparative Study of Health Indicators and Health Behaviour among Nurses and Early Childhood Educators.

The activities of health care workers and early childhood educators have received increased attention both in lay public discourse and in scientific discourse. These professional groups play a significant role in shaping the health behaviours of those they interact with; thus, understanding the patterns they convey is of paramount importance. The aim of our study is a comparative analysis of health conditions and health behaviours of professionals working in Hungarian early childhood education and nurses working in the healthcare system (n = 1591). We carried out our quantitative, cross-sectional research using convenience sampling among healthcare professionals working in nursing job positions (n = 581) and as early childhood educators (n = 1010), in south-west Hungary. Diagnosed chronic illnesses affect early childhood educators at a significantly higher rate (p < 0.05): the prevalence of musculoskeletal disorders is particularly high among them, as a result of which they reported a significant degree of physical limitation in relation to work. In the context of mental health, comparing the professional groups, nurses' indicators were significantly (p < 0.001) more unfavourable in all examined dimensions. Moreover, the comparison in terms of educational attainment directed attention to the worse indicators of non-graduates. In this context, early childhood educators are less affected by all three dimensions of burnout (p < 0.001). As for health behaviour, the smoking habits of nurses are more unfavourable (p < 0.05). Regarding screening tests, participation in cytological testing was significantly higher among nurses, whereas early childhood educators showed increased participation in mammography (p < 0.001). Our findings draw attention to the fact that early childhood educators are primarily affected by chronic musculoskeletal disorders, while healthcare workers are more affected by problems related to mental health. Mental well-being can be further endangered by the fact that both professional groups perceive low social appreciation for the work they carry out.

Musculoskeletal Disorders and Ergonomics Risk Assessment among Sewing Machine Operators and Tailors

Background: Sewing machine operators and tailors in Faisalabad, Pakistan, frequently endure prolonged periods of sitting or standing, performing repetitive tasks that contribute to Musculoskeletal Disorders (MSDs). This study aims to fill the research gap in work-related musculoskeletal disorders (WRMSDs) and workstation evaluations within this group. Objective: The purpose of this study was to assess the prevalence of MSDs and evaluate the ergonomic conditions of workstations among tailors and sewing machine operators in the local and textile sectors of Faisalabad. Methods: A cross-sectional study design utilized non-probability sampling to include 810 participants from both local tailor shops and textile factories. Data collection involved a self-structured questionnaire focusing on demographic and job-related factors, the Cornell Musculoskeletal Discomfort Questionnaire (CMDQ), and the Rapid Upper Limb Assessment (RULA) to evaluate ergonomic risks. Results: High levels of discomfort were reported in the upper limbs, particularly the right and left forearms (3.40±0.97), and in the lower limbs, particularly the right knee (3.90±0.47). The mean RULA scores were 4.8±0.51 for textile workers and 4.9±0.53 for local tailors, indicating poor workstation setups. Additionally, CMDQ results showed significant associations between musculoskeletal discomfort and variables such as age, residence, marital status, lifestyle, and smoking habits. Conclusion: The study found a high prevalence of musculoskeletal disorders among textile workers and tailors, particularly affecting the left foot and left knee of local tailors. The RULA scores highlight a high risk of musculoskeletal disorders, necessitating further investigations and modifications in the working environment.

Exploring multisite musculoskeletal symptoms among sewing machine operators in a tunisian leather and footwear industry using decision tree models

Background/objectivesSewing machine operators (SMO) are the most likely workers to experience a high prevalence of musculoskeletal disorders in the textile, clothing, and footwear industries. We conducted a cross-sectional and exhaustive study among SMO working in the leather and footwear industry to describe the prevalence of multi-site musculoskeletal symptoms (MMS) and evaluate factors associated with their occurrence. MethodsMusculoskeletal symptoms declared by these operators were assessed through the modified Nordic questionnaire. The psychosocial work environment was assessed using the Karasek model. The variables associated with MMS were issued from binary logistic regression and decision tree using R software. ResultsOf 145 operators, 65.5 % of men and 72.4 % of women had MMS. Based on binary logistic regression, a history of musculoskeletal disorders (MSDs) increased the risk of developing MMS by 8 folds. The binary decision tree identified five main nodes: history of MSDs, professional seniority, often finding the pace of work restrictive and male gender. ConclusionIdentifying homogeneous profiles of MMS's occurrence will help the implementation of an effective and targeted preventive strategy.

Work-related musculoskeletal disorders in dockworkers. Systematic review and meta-analysis.

Dockworkers are exposed to physical overloads that can contribute to the development of musculoskeletal disorders, leading to functional disability and absenteeism. to map, critically appraise, and synthesize the available evidence on the prevalence of musculoskeletal diseases associated with port occupational activities. A comprehensive search was conducted in structured and unstructured databases in August 2023, with no date or language restriction, to identify observational studies evaluating the prevalence of musculoskeletal disorders in dockworkers' occupational activity. The risk of bias was assessed using validated tools based on the included study designs. Data from studies were pooled in meta-analyses. The certainty of the evidence was assessed using the GRADE approach. We identified 12 analytical cross-sectional studies involving 7821 participants in ports of five countries. Most studies (75%) had a moderate methodological quality according to the Joanna Briggs Institute tool. Considering the overall worker categories and any musculoskeletal disorders, the meta-analysis showed a prevalence of 58% (95% Confidence Interval [95% CI] 37% to 78%), with degenerative spinal diseases 42% (95% CI -0.6% to 91%) and low back pain 36% (95% CI 21% to 50%) being the most prevalent conditions. Symptoms were predominantly in foremen and stevedores. The certainty of the evidence was very low. Musculoskeletal disorders seem prevalent among dockworkers, mainly degenerative spinal diseases and low back pain. Studies with greater methodological consistency are still needed to validate these hypotheses and assist in decision-making for implementing preventive and informational policies in maritime port management organizations.

The association between diabetes mellitus and musculoskeletal disorders: a systematic review and meta-analysis.

Despite the fact that DM patients are living longer, research on the prevalence of MSDs and other related illnesses is still lacking compared to that of other comorbidities. This study systematically reviewed and meta-analyzed cohort studies to determine the association between diabetes mellitus (DM) and musculoskeletal disorders (MSDs). A comprehensive search of international databases, including Medline (PubMed), Web of Science, Scopus, and Embase, was conducted up to June 2023 to identify relevant studies investigating the association between MSDs and DM. The meta-analysis included ten cohort studies with a total of 308,445 participants. The pooled risk ratio (RR) estimate for the association between MSDs and DM was 1.03 (95% CI 1.00-1.06). Based on subgroup analysis, the association between longer duration (more than 7), European, below the age of 70, and female patients was higher than the others. In conclusion, the results of this meta-analysis suggest that there may be an association between MSDs and diabetes in people with diabetes. These findings add to the existing knowledge on this topic and highlight the importance of recognition and management of MSDs in people with DM. There is a need for further research to investigate the underlying mechanisms and to develop targeted interventions for the prevention and management of MSDs in this population. https://www.crd.york.ac.uk/prospero/display_record.php?RecordID=381787, identifier CRD42022381787.

Čimbenici rizika i učestalost mišićno-koštanih tegoba radnika pri radu u tehnici batika uzrokovanih položajem tijela i rada mišića ruku

The batik industry as one of Malaysian cultural heritage is mainly located on the East Coast of Malaysia, particularly in the states of Kelantan and Terengganu. Most of the industry is home-based. Hence, the traditional batik work environment and tasks impose threats to the well-being of the artisans. This study investigates ergonomic issues and the prevalence of musculoskeletal disorders in two of Kelantan’s batik industries. The artisans’ natural working postures and the environments of the two places were observed and video recorded. Muscle activations on the wrist of the artisan doing the paint (canting) were imitated. Surface electromyography (sEMG) investigations were performed in the laboratory. A questionnaire survey was also distributed among craftsmen and artisans involved in the batik industry in Kelantan. Results illustrate evidence of the need to educate batik industries on ergonomic risk factors. According to the survey of 33 respondents, the most affected body parts are the waist (60%), back and feet (57%). The walkthroughs and site visits showed that batik making process demands awkward postures which include standing, precision handling of hand tools, trunk bending &amp; rotating and overreaching repetitively between 4 to 8 hours. The Rapid Upper Limb Assessment (RULA) index obtained from the assessments ranges from 7-8. It was also shown from the sEMG data that trunk bending affects muscle contraction of the wrist during painting movement. Therefore, immediate interventions are required to improve batik artisans’ postural working conditions, especially on the neck, trunk, legs, wrists and arms.

Musculoskeletal disorder prevalence and its correlation with stress in medical students: A cross sectional survey

ABSTRACT Background: The study aimed to evaluate musculoskeletal disorder (MSD) prevalence and its correlation with stress in medical students at Umm Al-Qura University (UQU) in Saudi Arabia. Methods: A total of 416 participants participated in this study by answering an online questionnaire. We included medical students from UQU of both genders, ranging from the first year to the sixth year. A questionnaire was used to capture sociodemographic data. The data were collected using the Kessler Psychological Distress Scale (K-10) and Standardized Nordic questionnaire. Results: Among 416 medical students surveyed, 219 (52.60%) were males. A significant proportion of participants, 294 (70.70%), reported experiencing pain during the last 12 months. Female students exhibited significantly higher scores of MSDs compared to their male counterparts. Students who reported working between 51–90 hours per week had a significantly higher MSD score than those who worked 0–50 hours or 91 or more hours. The findings of this study indicated that the most prevalent MSDs were low back pain (50.20%), followed by neck pain (31.70%), and female medical students exhibited significantly higher stress levels than male medical students. Conclusions: Musculoskeletal disorders represent a prevalent health issue among medical students, there is a significant association between factors such as being a female and body mass index. Additionally, psychological stress is a widespread concern among medical students, given the demanding nature of their lifestyle. Interestingly, our findings revealed that there exists a moderately positive relationship between musculoskeletal disorders and stress in this particular population.
