BACKGROUND

The COVID-19 pandemic brought insurmountable changes, leading to work demands and resource limitations that placed additional physical and occupational stress.

This study aimed to determine the change in the occurrence and intensity of musculoskeletal discomfort among selected university faculty members. It also determined the association of sociodemographic and anthropometric factors, workplace conditions, and involvement in physical activity with musculoskeletal pain.

This is an analytical cross-sectional study conducted from June 2022 to May 2023 that surveyed university faculty members from Metro Manila and Metro Cebu. Outcome measures include sociodemographic data, anthropometric measures of weight, height, body mass index, workplace conditions, exercise participation, and musculoskeletal discomfort using the Cornell Musculoskeletal Discomfort Questionnaire.

Data from 120 participants, mostly female, with an average BMI of 27.78 ± 12.09 kg/m2 and 11.82 ± 10.39 years of teaching experience revealed increased computer usage and reduced teaching hours during the Pandemic lockdown. There was also prevalent musculoskeletal discomfort (MSD), particularly in the neck, shoulder, and upper back. Factors associated with increased MSD were female gender, longer computer use, and pre pandemic MSD history.

This study underscores the significance of addressing ergonomic factors and work conditions to mitigate MSD risks among educators during challenging situations.

INTRODUCTION: Due to COVID-19 pandemic, many have shifted into working at home which led to physical inactivity. This may cause musculoskeletal discomfort, chronic disease, muscle atrophy and spinal imbalance due to improper and prolonged sitting posture. Since mobile devices are relatively available for most of the office workers, there were still a lack of evidence-based mobile applications that can counteract the inactivity through exercises, which led to the researchers to create an application called SitMate that consists of evidence-based exercises which aimed to prevent musculoskeletal discomfort among a business process outsourcing company Workforce Management Personnel (BPO-WMP). METHODS: Eleven participants (18-40 years old) full-time, work-from-home BPO-WMP were randomized into Treatment Group(TG)(n=6) and Control Group (CG)(n=5). The TG received one month intervention with the use of SitMate Application containing relaxation exercises, range of motion exercises and stretching exercises, and notifications for postural correction while the CG continued their usual working schedule. RESULTS: There were no significant differences between two groups on all body parts that were measured using the Cornell Musculoskeletal Discomfort Questionnaire, and no significant differences in the intragroup pre-test and post-test scores on all body parts between TG and CG. For the intra-group post-test of the TG, there were noted improvements on the hip/buttock, right shoulder, upper back (median = 0) and right wrist (median = 1.5). There was also a noted increase in discomfort on the neck (median = 1.5) and lower back (median = 3). For the post-test of the CG, there were noted improvements on the right shoulder, right wrist (median = 0) and lower back (median = 1.5). CONCLUSION This study has shown that the SitMate application does not effectively reduce the prolonged sitting-related discomfort among the personnel after 1 month of intervention.

Objective: To analyze the clinical characteristics of infection of COVID-19 Omicron variants in children with allergic diseases. Methods: This was a cross-sectional retrospective study. A total of 657 pediatric patients with allergic diseases aged between 0-17 years confirmed with COVID-19 infection were enrolled from the Children's Hospital affiliated to Capital Institute of Pediatrics from January to March 2023. The median age was 6.6(4.7,9.9) years, with 443 males (67.4%) and 214 females (32.6%). Demographic data, vaccination status, clinical manifestations, therapeutic drugs, and other data were collected. The patients were then divided into different groups according to the age, type of allergic diseases and vaccination status, and their clinical characteristics were compared. Results: A total of 657 children with allergic diseases were included in this study, among them 568 with asthma. Fever is the most common symptoms after COVID-19 infection (627/657, 95.4%), and 509 children (77.5%) with high fever. Cough was observed in 446 (67.9%) and fatigue in 167 (25.4%) cases.10 cases (1.5%) were diagnosed as pneumonia. The proportion of pharyngalgia(22%,84/382, χ²=19.847, P<0.01), fatigue (31.7%, 121/382,χ²=23.831, P<0.01), headache(34.6%, 132/382,χ²=57.598, P<0.01), muscle joint pain(16.0%, 61/382,χ²=22.289, P<0.01) and vomiting(11.0%, 42/382,χ²=12.756, P<0.01) were highest in the>6 years group. Children younger than 3 years had the lowest proportion of runny nose(8.8%, 5/57,χ²=8.411, P<0.01), cough(45.6%, 26/57,χ²=6.287, P<0.05) and expectoration(7.0%, 4/57,χ²=5.950, P<0.05). 62.8%(137/218) of the patients in 3-6 year group had the highest rate of cough(χ²=6.287, P<0.05), with a higher proportion of wheezing (10.1%, 22/218). Cough and/or wheezing symptoms were most quickly relieved in the 6 year old group, who had a highest proportion of 68.8%(260/382) in duration of respiratory symptoms within 1 week compared with 52.2% (114/218)of 3-6 years group and 41.2% (22/57)of<3 year group, respectively(χ²=23.166, P<0.01). The asthma group had a significant higher proportion of cough(59.7% vs 41.6%, χ²=10.310, P<0.01), wheezing (8.5% vs 0.0%, χ²=8.114, P<0.01) and expectoration (19.2% vs 7.9%, χ²=10.310, P<0.01) than that of non-asthma group. Besides, patients with cough and/or wheezing in the asthma group had more impact on exercise and sleep (16.1% vs 0, χ²=5.436, P<0.05) and a longer duration over 4 weeks (25.1% vs 3.7%, χ²=6.244, P<0.05). Conclusions: The most common symptoms in children with allergy infected with COVID-19 Omicron variant were fever and cough. Children under 3 years of age had relatively fewer respiratory symptoms while those with asthma or aged 3-6 years were more likely to have cough and wheezing and longer duration of symptoms. The data suggested that the prevention and management of COVID-19 should be strengthened in children with allergy.

OBJECTIVE: To investigate the significance of anti-histidyl tRNA synthetase (Jo-1) antibody in idiopathic inflammatory myopathies (IIM) and its diseases spectrum. METHODS: We enrolled all the patients who were tested positive for anti-Jo-1 antibody by immunoblotting in Peking University People's Hospital between 2016 and 2022. And the patients diagnosed with anti-synthetase antibody syndrome (ASS) with negative serum anti-Jo-1 antibody were enrolled as controls. We analyzed the basic information, clinical characteristics, and various inflammatory and immunological indicators of the patients at the onset of illness. RESULTS: A total of 165 patients with positive anti-Jo-1 antibody were enrolled in this study. Among them, 80.5% were diagnosed with connective tissue disease. And 57.6% (95/165) were diagnosed with IIM, including ASS (84/165, 50.9%), immune-mediated necrotizing myopathy (7/165, 4.2%) and dermatomyositis (4/165, 2.4%). There were 23.0% (38/165) diagnosed with other connective tissue disease, mainly including rheumatoid arthritis (11/165, 6.7%), undifferentiated connective tissue disease (5/165, 3.0%), interstitial pneumonia with autoimmune features (5/165, 3.0%), undifferentiated arthritis (4/165, 2.4%), Sjögren's syndrome (3/165, 1.8%), systemic lupus erythematosus (3/165, 1.8%), systemic vasculitis (3/165, 1.8%), and so on. Other cases included 3 (1.8%) malignant tumor patients, 4 (2.4%) infectious cases and so on. The diagnoses were not clear in 9.1% (15 /165) of the cohort. In the analysis of ASS subgroups, the group with positive serum anti-Jo-1 antibody had a younger age of onset than those with negative serum anti-Jo-1 antibody (49.9 years vs. 55.0 years, P=0.026). Clinical manifestations of arthritis (60.7% vs. 33.3%, P=0.002) and myalgia (47.1% vs. 22.2%, P=0.004) were more common in the ASS patients with positive anti-Jo-1 antibody. With the increase of anti-Jo-1 antibody titer, the incidence of the manifestations of arthritis, mechanic hands, Gottron sign and Raynaud phenomenon increased, and the proportion of abnormal creatine kinase and α-hydroxybutyric dehydrogenase index increased in the ASS patients. The incidence of myalgia and myasthenia were significantly more common in this cohort when anti-Jo-1 antibody-positive ASS patients were positive for one and more myositis specific antibodies/myositis associated autoantibodies (P < 0.05). CONCLUSION The disease spectrum in patients with positive serum anti-Jo-1 antibody includes a variety of diseases, mainly ASS. And anti-Jo-1 antibody can also be found in many connective tissue diseases, malignant tumor, infection and so on.

This study aims to explore the efficacy and safety of Lianhua Qingwen preparations combined with Oseltamivir in the treatment of influenza patients. PubMed, Cochrane Library, EMbase, SinoMed, CNKI, Wanfang, and VIP were searched for the randomized controlled trials(RCTs) involving the comparison between the influenza patients treated with Lianhua Qingwen preparations combined with Oseltamivir and those treated with Oseltamivir alone. Fever clearance time was taken as the primary outcome indicator. Clinical effective rate(markedly effective and effective), time to muscle pain relief, time to sore throat relief, time to cough relief, time to nasal congestion and runny nose relief, time to negative result of viral nucleic acid test, and adverse reactions were taken as the secondary outcome indicators. The data were extracted based on the outcome indicators and then combined. The Cochrane collaboration's tool for assessing risk of bias was used to evaluate the quality of a single RCT, and the grading of recommendations assessment, development and evaluations(GRADE) system to assess the quality of a single outcome indicator. RevMan 5.3 was employed to analyze data and test heterogeneity. Finally, 16 RCTs involving 1 629 patients were included for analysis. The Meta-analysis showed that Lianhua Qingwen preparations combined with Oseltamivir was superior to Oseltamivir alone in the treatment of influenza in terms of clinical effective rate(RR=1.16, 95%CI [1.12, 1.20], P<0.000 01), fever clearance time(SMD=-2.02, 95%CI [-2.62,-1.41], P<0.000 01), time to muscle pain relief(SMD=-2.50, 95%CI [-3.84,-1.16], P=0.000 2), time to sore throat relief(SMD=-1.40, 95%CI [-1.93,-0.85], P<0.000 01), time to cough relief(SMD=-1.81, 95%CI [-2.44,-1.19], P<0.000 01), time to nasal congestion and runny nose(SMD=-2.31, 95%CI [-3.61,-1.01], P=0.000 5), and time to negative result of viral nucleic acid test(SMD=-0.68, 95%CI [-1.19,-0.16], P=0.01). However, due to the low quality of the trials, the above conclusions need to be proved by more high-quality clinical studies. In addition, we still need to attach importance to the adverse reactions of the integrated application of Chinese and western medicines.

Objective: To investigate the influence of individual factors and labor organization on the prevalence of neck pain (hereinafter referred to as neck pain) in automotive assemblers, and to provide a basis for enterprises to optimize neck pain interventions. Methods: A cluster random sampling method was taken in January 2021, at an automobile manufacturing plant in Shiyan, 656 assemblers with ≥1.0 years of service were selected, the "Musculoskeletal Disorder Questionnaire" was used to investigate the incidence and influencing factors of neck pain. Pearson χ(2) test or trend χ(2) test was used to compare the data rates. The influencing factors of neck pain were analyzed by multivariate logistic regression. Results: The prevalence rate of neck pain (hereinafter referred to as the prevalence rate of neck pain) of automobile assemblers within one year was 53.94% (342/634) . The prevalence of neck pain in women was higher than that in men (69.1% vs 48.6%, P<0.01) . The prevalence of neck pain was related to length of service, self-assessment of fatigue, working hours per week, working in the same workshop, rest days per shift, and accumulated rest time per shift (P<0.05) . Multivariate logistic regression analysis showed that the risk of neck pain in women was 2.434 times higher than that in men; The risk of neck pain increased by 18.9% for each hour of work per week; Rest during work was a protective factor for neck pain. The number of rest per shift increased and the risk of neck pain decreased (r=0.405, 0.311, 0.302, 95%CI=0.205~0.803, 0.169~0.572, 0.142~0.642, P<0.05) . Conclusion: The annual prevalence of neck pain was higher in automobile assemblers. Enterprises should fully consider the influencing factors such as gender, working hours per week and the number of breaks when arranging production.

BACKGROUND: Corona virus disease 2019 (COVID-19) has spread around the world since its outbreak, and there is no ascertained effective drug up to now. Lianhua Qingwen (LHQW) has been widely used in China and overseas Chinese, which had some advantages in the treatment of COVID-19. OBJECTIVE: To evaluate the efficacy and safety of LHQW for COVID-19 by conducting a systematic review with meta-analysis. METHODS: A comprehensive literature search was conducted in 12 electronic databases from their establishment to October 30, 2021. Note Express 3.2.0 was used for screening of trials, and the data was independently extracted in duplicate by 2 researchers. The risk of bias of randomized controlled trials (RCTs) and retrospective studies were assessed by using the Cochrane collaboration tool and Newcastle Ottawa Scale, respectively, followed by data analysis using RevMan 5.3. The RCTs or retrospective studies to treat COVID-19 using LHQW were included. The intervention measures in the experimental group were LHQW alone or combined with chemical drugs (LCWC), and that in the control group were chemical drugs (CDs). Outcome measures included computed tomography (CT) recovery rate, disappearance rates of primary (fever, cough, fatigue), respiratory, gastrointestinal and other symptoms, exacerbation rate and adverse reaction. Subgroup analysis was conducted according to whether LHQW was combined with CDs and the different treatment methods in the control group. RESULTS: Nine trials with 1,152 participants with COVID-19 were included. The CT recovery rates of LHQW and LCWC were 1.36 and 1.32 times of CDs, respectively (P<0.05). Compared with CDs, LCWC remarkably increased the disappearance rates of fever, cough, fatigue, expectoration, shortness of breath, and muscle soreness (P<0.05). LHQW also obviously decreased the exacerbation rate, which was 0.45 times of CDs alone (P<0.05). There was no obvious difference between LCWC and CDs in adverse reaction (P>0.05). CONCLUSIONS LHQW was more suitable for treating COVID-19 patients with obvious expectoration, shortness of breath and muscle soreness. LHQW had advantages in treating COVID-19 with no obvious exacerbation. (PROSPERO No. CRD42021235937).

OBJECTIVE: To explore the genetic basis of a Chinese pedigree affected with Becker muscular dystrophy (BMD) with myalgia as the main feature. METHODS: Clinical data of the patients and results of auxiliary examinations were retrospectively analyzed. Multiplex ligation-dependent probe amplification and high-throughput sequencing were used to detect potential variants. Sanger sequencing was used to verify the results. RESULTS: The clinical manifestations of the proband included myalgia and elevated serum creatine kinase, which is similar to another patient from the pedigree. Genetic testing revealed that the two patients both harbored hemizygous deletions of exons 10 to 29 of the DMD gene, for which the mother was a carrier. The same deletion was not found in his father. Based on the guidelines from American College of Medical Genetics and Genomics, the deletion was predicted to be pathogenic (PVS1+PM2+PP1). CONCLUSION Myalgia with elevated serum CK may be atypical clinical manifestations of BMD and may be associated with variants in the rod domain of the DMD gene. The deletion of exons 10 to 29 of the DMD gene probably underlay the BMD in this pedigree.

Introduction: Musculoskeletal complaints have been observed in the recovery phase of patients with moderate-to-severe coronavirus disease 2019 (COVID-19). We noted several referrals for physical rehabilitation at the University of the Philippines-Philippine General Hospital (UP-PGH), a designated COVID-19 referral center. These observations resembled the musculoskeletal manifestations associated with poorer outcomes reported in other coronavirus studies. Objectives: The study determined the musculoskeletal signs and symptoms of adults in the recovery phase of moderate to severe COVID-19 using the COVID Musculoskeletal Assessment Tool (CMAT). Methods: This was a three-phased, prospective, descriptive study of adults admitted for COVID-19 at the UP-PGH. Phase 1 was the development of the CMAT based on a review of related literature and patient charts, and patient interviews. The tool was pretested and validated in Phase 2 before it was used in the evaluation of study participants in Phase 3 of the research. Data was encoded using Microsoft® Excel 2007 and analyzed using STATA, Version 12.0 (Texas, USA). Descriptive statistics were used to summarize the variables collected for the study. Results: A cohort of 40 patients admitted at the UP-PGH for moderate-to-severe COVID-19 infection was evaluated using the CMAT. Most of the patients had an average age of 55 years and were males. Majority resided in an urban area, reached high school education, and were ambulatory before their illness. The most common comorbidities were hypertension and diabetes. All patients required oxygen support. Based on the CMAT, majority of the participants complained of muscle pain, generalized weakness, and easy fatigability. Other common findings were neck-shoulder and lower limb pain, dyspnea on exertion, limited mobility in the trunk, hips, and knees, joint pains, and decreased muscle strength. Half of the participants needed a wheelchair or walker to ambulate. These findings may be due to the COVID-19 disease and to prolonged confinement in bed. Only one patient underwent physical therapy through bedside instructions. Conclusion Musculoskeletal signs and symptoms were common in the patients recovering from COVID-19 disease. The COVID-19 Musculoskeletal Assessment Tool facilitated the evaluation of patients and the recording of results. Early referral for medical rehabilitation and timely intervention are strongly recommended.
