Musculoskeletal disorders (MSDs) can be characterized from their occupational etiology and their occurrence; their chronicity generates negative repercussions for the health of workers, especially of artisanal fishing. To investigate the prevalence of generalized musculoskeletal disorders by body region and self-reported pain in a fishing population of northeastern Brazil, an epidemiological cross-sectional study was carried out in Santiago do Iguape, Bahia-Brazil, in 2017. The Brazilian version of the Nordic Musculoskeletal Questionnaire (NMQ), in addition to a questionnaire containing the socio-demographic and labor conditions were applied to a random stratified sample of 248 artisanal fisheries. There were 170 female shellfish gatherers and 78 fishermen, with a mean age of 36.7 years (SD = 10.5 years) and 43.3 years (SD = 11.8 years), respectively. The beginning of the labor activity was initiated at approximately 11 years of age. The average weekly income varied from 17.64 USD to 29.10 USD. The prevalence of MSD independent of occupation occurred in at least one body region in 93.5% and the presence of musculoskeletal pain/discomfort over the last seven days in 95.2% of the fishing workers. The highest prevalence of MSD was found in shellfish gatherers in: lower back (86.4%), wrist and hand (73.5%), and upper back (66.8%). In relation to the presence of pain in the last year, the frequency of pain was greater in the fishermen compared to the shellfish gatherers. The generalized severity of the MSD in 93.5% of this community of fishermen is evident, with emphasis in the following regions: lower back, wrist and hand and upper back in both groups, with occurrence of pain in more than one body region at the same time.

Abstract: Intervertebral disc (IVD) degeneration is a leading cause of lower back pain. Although the etiology of IVD degeneration (IVDD) is unclear, excessive oxidative stress, inflammation and apoptosis and disruption of autophagy play important role in the pathogenesis of IVDD. Therefore, finding a solution to mitigate these processes could stop or reduce the development of IVDD. Melatonin, a powerful antioxidant, plays an important role in regulating cartilage tissue hemostasis. Melatonin inhibits destruction of extracellular matrix (ECM) of disc. Melatonin preserves ECM contents including sox-9, aggrecan, and collagen II through inhibiting matrix degeneration enzymes such as MMP-13. These protective effects may be mediated by the inhibition of oxidative stress, inflammation and apoptosis, and regulation of autophagy in IVD cells.

Introduction. Chronic back pain syndrome, which significantly restricts a person’s daily activity, can cause the formation of depressive states and is a significantly more difficult task for treatment compared to acute pain.Aim. To evaluate the efficacy and safety of caudal epidural catheterization (CEC) and local therapy with anesthetics and glucocorticoids for chronic nonspecific discogenic and chronic radicular low back pain (LBP) in young and middle-aged patients.Materials and methods. 42 patients aged from 29 to 59 years, who in the neurosurgical department of the Vologda City Hospital No. 1 in 2017–2019 underwent an operation to install a caudal epidural catheter and prolonged injection therapy of local anesthetics and glucocorticosteroids for chronic nonspecific discogenic and chronic radicular LBP.Results. There were no purulent-septic complications, hematomas of the spinal canal. In the group of patients with radicular syndrome the average values of LBP according to VAS were as follows: before CEC – 78.5 mm; 5 days after CEC – 24.1 mm; 6 months after CEC – 19.6 mm; after 12 months – 17.9 mm. In the group of patients with nonspecific discogenic LBP the average pain estimates for VAS were as follows: before CEC – 78.1 mm; 5 days after CEC – 21.7 mm; 6 months after CEC – 20.9 mm; after 12 months – 23.4 mm.Сonclusion. Our experience indicates a high long-term efficacy and safety of treatment with caudal epidural catheterization and local prolonged therapy with anesthetics and glucocorticoids for chronic radicular and chronic nonspecific discogenic pain in the lower back in young and middle-aged patients selected on the basis of a special system of criteria.

Background: This study has been carried out to analyze the prevalence of self-reported work-related musculoskeletal symptoms among software professionals and to utilize the findings to design an effective preventive interventional program for WRMSDs. Subjects & Methods: This cross-sectional descriptive data analysis was done among 665 software employees both male and female from various companies in Q city Tech Park, Hyderabad. Data collected with “Cornell Musculoskeletal Discomfort Questionnaire” (CMDQ). Results: A total of 640 subjects were eligible for this study. Prevalence of WRMSDs to be 67%. The most common sites of reported symptoms are neck (65.0%), upper back (56.4%), lower back (62.6%), right shoulder (41.4%), left shoulder (35.4%) and right thigh (41.4%). Women were more likely to report symptoms in neck, lower back and both shoulder region than men (p<0.05). Discomforts in neck, lower back and right shoulder are greatly shown impact on work performance. Conclusion: WRMSDs are highly prevalent is software professionals and women at more risk than men. These findings indicate the need for more attention to WRMSDs and design of effective preventive strategies. Keywords: musculoskeletal pain, Prevalence, software professionals, work related musculoskeletal disorders.

IntroductionChronic lower back pain (CLBP) is a frequent cause of medical consultations worldwide, and it results in decreased quality of life and disability. Current treatments for CLBP are often not effective, and alternatives are urgently needed. Three promising possibilities have emerged: (1) open-label placebo treatment reduces chronic pain, (2) placebo treatment is as efficacious as opioid treatment with a high correlation between patient expectation and treatment outcome, and (3) observing positive effects in another patient can improve functional capacity. We hypothesise that treatment expectations can be positively influenced through social observation and improve treatment outcome.Methods and analysisIn our clinical trial, we will randomise patients with CLBP into five groups. Two groups receive either a 3 week course of treatment with an analgesic (ANA) (metamizole/dipyrone) or with open-label placebos (OLP). For one of each group, we will build treatment expectations through observational learning and assess its impact on the treatment. For this purpose, one group each will watch either a positive or a neutral video. The intervention groups will be compared with a control group that will not be given any medication or observational learning. Participants will be recruited via all institutions in the Hamburg metropolitan area that treat patients with CLBP. Patients are eligible for inclusion if they are at least 18 years or older, have CLBP (of at least 3 months duration), and agree to potentially receive an active ANA or an OLP. Patients with pain-related “red flags” will be excluded. The study requires 150 participants (30 participants per group) to assess the differences in the primary outcome, pain intensity. Secondary outcomes include changes in treatment expectations, anxiety, comorbid depression, stress-related neuroendocrine measures, functional and structural connectivity, functional capacity, and ANA consumption. All outcomes and treatment expectations will be measured before and after the intervention and 3 months post-intervention.Ethics and disseminationEthical approval was obtained in January 2020 from the Hamburg Medical Ethics Council (ref number PV7067). Outcomes will be disseminated through publications in peer-reviewed journals and presentations at national and international conference meetings.Trial registration numberThe approved trial protocol was registered at the German Clinical Trials Register (DRKS) and can be found at drks.de (Identifier: DRKS00024418).

Musculoskeletal disorders are disorders that occur in one of the skeletal organs or muscles of the body such as congenital abnormalities in the upper and lower extremities, nerve and muscle disorders, inflammatory infections of bones and joints, musculoskeletal metabolic disorders, degenerative musculoskeletal disorders (spine, upper extremities) and below). The study aimed To analyze the static condition of the workers' complaints of musculoskeletal disorders (MSDs). Using literature review with scoping review method. The data was collected through internet searches using Google Scholar and PubMed with the keywords static conditions, complaints of MSDs, ergonomic position, musculoskeletal disorders, the influence of static conditions, with a range of research years is 2015-2020. Results found 83 articles matching the keyword. A review of 9 research articles that met the inclusion criteria found 4 aspects, namely the factor of length of work more than 1 year, age, working hours and using the same extremity for a long period of time will increase the risk of MSDs, Doing work in awkward positions for 5- 8 hours/day increases the risk of MSDs in workers, especially nurses, The emergence of MSDs symptoms is higher in women, namely in the lower back and neck area, The pain felt due to MSDs disorders can be severe, namely in the lower back, shoulders, neck, wrists , knees and ankles. There is a relationship with static positions/non-ergonomic conditions at work, these non-ergonomic conditions do not directly cause complaints but in the long term complaints will arise. The female gender is at high risk of experiencing MSDs, the length of work and length of time working will affect the emergence of MSDs, there are 12 static conditions found in someone when doing work, the main complaint that appears in MSDs is pain.

Hernia Nucleus Pulposus (HNP) is one of the causes of lower back pain due to heavy mechanical loads for a long time. HNP if not treated immediately it can cause fluid buildup and swelling that can cause permanent nerve damage. This study is a quantitative study with a quasi-experimental pre-test-post-test design with a control group divided into 3 groups. The sampling technique was using probability sampling method as many as 30 respondents who visited Grandmed Lubuk Pakam Hospital. The results of the statistical test showed that there was an effect of McKenzie and Core Stability Exercise on reducing pain in patients with HNP with a p value of 0.020 <0.05.
