Application prospects of urine-derived stem cells in neurological and musculoskeletal diseases

Urine-derived stem cells(USCs)are derived from urine and harbor the potential of proliferation and multidirectional differentiation.Moreover,USCs could be reprogrammed into pluripotent stem cells[namely urine-derived induced pluripotent stem cells(UiPSCs)]through transcription factors,such as octamer binding transcription factor 4,sex determining region Y-box 2,kruppel-like factor 4,myelocytomatosis oncogene,and Nanog homeobox and protein lin-28,in which the first four are known as Yamanaka factors.Mounting evidence supports that USCs and UiPSCs possess high potential of neurogenic,myogenic,and osteogenic differentiation,indicating that they may play a crucial role in the treatment of neurological and musculoskeletal diseases.Therefore,we summarized the origin and physiological characteristics of USCs and UiPSCs and their therapeutic application in neurological and musculoskeletal disorders in this review,which not only contributes to deepen our understanding of hallmarks of USCs and UiPSCs but also provides the theoretical basis for the treatment of neurological and musculoskeletal disorders with USCs and UiPSCs.

Epidemiological Patterns of Work-Related Musculoskeletal Disorders among Healthcare Workers in Five Reference Hospitals in the City of Douala, Cameroon

Introduction: Work-related musculoskeletal disorders (WRMSDs) are a public health problem and have forced many workers to quit their jobs prematurely. This study investigated the prevalence and risk factors of WRMSDs among Healthcare workers in five reference hospitals in the City of Douala-Cameroon. Methods: A cross-sectional study was conducted in 2022 among 561 healthcare workers working in five reference hospitals in the city of Douala, Cameroon. Participants were selected using a convenient sampling technique. Data were collected with structured questionnaires;data on the demographics and risk factors were collected using a well-designed questionnaire, while estimation of the prevalence of WRMSDs was done using the Modified Nordic questionnaire. Results: The overall prevalence rate of WRMSDs among healthcare workers in Douala hospitals was 83.4% (468/561). The prevalence per professional groups was as follows: 88.8% (71) for Medical Laboratory Scientists (MLS), 81.9% (289) for nurses, 21 (80.8%) for Physiotherapists (PTs) and 78.8% (41) for Medical Doctors (MDs). There was a significant difference (p = 0.001) in the prevalence of WRMSDs with respect to place of work where healthcare workers from HLD recorded the highest prevalence 89.9%, while Healthcare workers from NBDH were 2.91 times at risk (AOR = 2.91;95% CI: 1.32 - 6.41;p = 0.001) to develop WRMSDs than healthcare workers in the other hospitals. With respect to body region, the highest prevalence of WRMSDs was recorded on the lower back, 58.8% with the lowest at the elbows 11.2%. The age group 30 to 39 years was significantly associated with WRMSDs at level of the shoulder (p = 0.002), upper back (p = 0.019), elbows (p Conclusion: The overall prevalence rate of WRMSDs among healthcare workers in Douala hospitals was high. The prevalence of WRMSDs is highest among MLS and nurses and the most affected body parts are;lower back, neck and upper back. Working on the same posture, stressful job, and repetitive tasks were the major risk factors associated to WRMSDs among healthcare workers in Douala hospitals.

Frequency of Comorbid Musculoskeletal Problems in Patients with Parkinson’s Disease: What and When?

Background: Musculoskeletal problems, deteriorating posture and pain are common complaints/comorbidities in Parkinson’s disease (PD). The aim of this study was to investigate the frequency of comorbid musculoskeletal problems in PD, and their relationship with disease stage and severity. Methods: The study was approved by the local ethical committee of Duzce University numbered with 2018/52 on date 26.03.2018. Patients with PD (pwPD) underwent a detailed examination to investigate the possible comorbidity of musculoskeletal findings in the orthopedics and traumatology clinic. Socio-demographic features, disease characteristics, motor and non-motor scores were recorded. Results: Thirty-seven pwPD were enrolled in the study. Mean age was 68.75 ± 10.75 years. Comorbid musculoskeletal problems were rotator cuff syndrome (27%), knee osteoarthritis (24.3%), meniscus (13.5%), lumber disc herniation (10.8%), kyphosis (8.1%), myotendinous diseases (16.3%). Rotator-cuff disease and knee osteoarthritis were most common comorbidities, especially in the “mild” and “moderate” stages of pwPD. Conclusion: Since most of the pwPD, especially the ones that have musculoskeletal complaints prior to the diagnosis of PD, present to the orthopedics and traumatology clinics or physiotherapists, it is mandatory to enhance the awareness of the orthopedic surgeons, and physiotherapy specialist in order to keep PD in mind.

Hepatomusculoskeletal disorders:Coining a new term might improve the management of the musculoskeletal manifestations of chronic liver disease

Chronic liver disease can affect many body systems including the musculoskeletal system.The pathogenetic crosstalk between the liver and organs such as the brain and the kidneys has already been described with compound terms merging the organs affected by the pathology,such as the hepatorenal syndrome.Nevertheless,the musculoskeletal manifestations of chronic liver disease have not been coined with such a term to date.Because of this shortage,documenting the musculoskeletal implications of chronic liver disease in both research and clinical practice is challenging.To fill this gap,the authors propose the term hepatomusculoskeletal disorders,a compound term of Greek origin that encompasses all the body structures involved in the aforementioned pathologic crosstalk.

Is burnout a mediating factor between sharps injury and workrelated factors or musculoskeletal pain?

BACKGROUND Burnout,musculoskeletal pain,and sharps injuries(SIs)affect medical workers.AIM To establish a model between SIs,burnout,and the risk factors to assess the extent to which burnout affects SIs.METHODS This questionnaire was used for an observational and cross-sectional study,which was based on members at a hospital affiliated with a medical university in Taichung,Taiwan,in 2020.The valid responses constituted 68.5%(1734 of 2531).The items were drawn from the Nordic Musculoskeletal Questionnaire and Copenhagen burnout inventory and concerned work experience,occupational category,presence of chronic diseases,sleep duration,overtime work,and work schedule.Factor analysis,chi-square test,Fisher exact test,Multiple linear,logistic regression and Sobel test were conducted.The present analyses were performed using SAS Enterprise Guide 6.1 software(SAS Institute Inc.,Cary,NC,United States),and significance was set at P<0.05.RESULTS Personal and work-related burnout ranks, sex, work experience ranks, occupationalgroups, drinking in the past month, sleep duration per day, presence ofchronic diseases, overtime work ranks, and work schedule were associated withSIs. Frequent upper limb and lower limb pain (pain occurring every day or once aweek) determined to be related to SIs. High personal burnout (> Q3) and highwork-related burnout (> Q3) mediated the relationship between SIs and frequentlower limb pain. Similarly, frequent lower limb pain mediated the relationship ofSIs with high personal and high work-related burnout. High personal and highwork-related burnout mediated the relationships of SIs with overtime work andirregular shift work. The mediating model provides strong evidence of anassociation between mental health and SIs.CONCLUSIONBurnout was determined to contribute to SIs occurrence;specifically, it mediatedthe relationships of SIs with frequent musculoskeletal pain, overtime work, andirregular shift work.

Immunosuppressive therapy selectively modulates B-cell responses in patients with rheumatic and musculoskeletal diseases receiving the inactivated COVID-19 vaccine

Background:Immunosuppressive medication reduces the immunogenicity of the coronavirus disease 2019(COVID-19)vaccines in patients with rheumatic and musculoskeletal diseases(RMDs).However,the underlying mechanism remains unclear.The primary aim of our study was to dissect the impact of immunosuppressive medication on cellular and humoral immune responses in RMD patients receiving the inactivated COVID-19 vaccine.Methods:A total of 28 RMD patients and five healthy controls(HCs)receiving two doses of the inactivated COVID-19 vaccine(Sinovac-CoronaVac)were prospectively enrolled.Blood samples were collected before the primary vaccination(Week 0)and one week after the second vaccination(Week 5).Neutralizing antibody(nAb)titers and autoantibody titers were measured by a pseudovirus-based neutralization assay and enzyme-linked immunosorbent assay,respectively.CD4^(+)T-cell and CD19^(+)B-cell subsets and serum cytokines were analyzed by flow cytometry.Results:The inactivated COVID-19 vaccine was immunogenic in RMD patients and HCs after the second vaccination,but the nAb titers were lower in RMD patients than those in HCs.Only patients with systemic lupus erythematosus(SLE)had notably increased nAb titers.Remarkably,IgG^(+)CD27^(+),IgG^(+)IgG1^(+),and IgG^(+)IgG1^(−)B cells were reduced,whereas IgG−IgG1^(+)B cells,and total IgA and IgG titers were markedly increased.However,Tfh cell and Tfr cell subsets and cytokines produced by Tfh cells were not increased.The flare rate was low in RMD patients with comparable autoantibody titers,unchanged CD4^(+)T cell subsets and serum proinflammatory cytokines(interleukin[IL]-6,IL-17,interferon-γ,and tumor necrosis factor-α)after the second vaccination.Conclusions:Immunosuppressive therapy decreased the immunogenicity of the vaccine and maintained a low flare rate by selectively modulating B cell but not CD4^(+)T cell responses in RMD patients receiving the inactivated COVID-19 vaccine.Optimization of the treatment regimen might ensure a durable and robust COVID-19 vaccination response.
