Role of frailty in predicting prognosis of older patients with lung cancer: An updated systematic review and meta-analysis.

INTRODUCTION: Frailty is a syndrome affecting primarily older adults that can impact disease course, treatment, and outcomes in patients with lung cancer (LC). We systematically reviewed current data on the correlation between frailty and overall survival (OS), recurrence-free survival (RFS), and the risk of complications in older patients with LC. MATERIALS AND METHODS: PubMed, EMBASE, and Scopus databases were searched for observational cohort, cross-sectional, and case-control studies involving participants aged 18 years or older diagnosed with LC. Eligible studies were required to perform frailty assessments and have non-frail participants as a comparator group. Random-effects models were used for analysis, and the reported effect sizes were represented as hazards ratio (HR) or odds ratios (OR) with associated 95% confidence intervals (CI). RESULTS: Seventeen studies were included, most with a retrospective cohort design (n = 16) and patients with non-small cell lung carcinoma (NSCLC). Older patients with LC and frailty had lower OS (HR 1.70, 95% CI: 1.39, 2.07) and RFS (HR 2.50, 95% CI: 1.02, 6.12), compared to non-frail subjects. Frail subjects also had increased risk of complications (OR 1.89, 95% CI: 1.42, 2.53). DISCUSSION: The observed association between frailty and OS, RFS, and an increased susceptibility to complications emphasizes the potential significance of frailty status as a substantial prognostic indicator. Our results underscore the vital role of including frailty assessment as an integral element within the management plan for patients dealing with lung cancer.

The impact of sarcopenia on prognosis of patients with pancreatic cancer: A systematic review and meta-analysis.

OBJECTIVE: To summarize recent findings on the association of low skeletal muscle mass and muscle quality with overall survival and recurrence-free survival in patients with pancreatic cancer. METHODS: A systematic search was conducted using Medline (via PubMed), Embase and Scopus databases for observational studies reporting on the overall survival and recurrence-free survival. Pooled effect sizes were reported as hazards ratio along with 95% confidence intervals. RESULTS: A total of 34 studies were included. Low skeletal muscle index (indicating muscle mass) was associated with poor overall survival (hazards ratio: 1.50; 95% confidence interval: 1.34, 1.67) and lower recurrence-free survival (hazards ratio: 1.28, 95% confidence interval: 1.15, 1.43). Low skeletal muscle attenuation (indicating muscle quality) was associated with poor overall survival (hazards ratio: 1.32; 95% confidence interval: 1.05, 1.66). Recurrence-free survival was similar in patients with low and normal/high skeletal muscle attenuation (hazards ratio: 1.12, 95% confidence interval: 0.89, 1.40). CONCLUSION: Both low skeletal muscle mass and poor muscle quality are associated with poor long-term survival. Low skeletal muscle index, but not low skeletal muscle attenuation, are associated with poor recurrence-free survival.

Association of Body Mass Index and Acute Kidney Injury Incidence and Outcome: A Systematic Review and Meta-Analysis.

This study aims to provide pooled estimates for the incidence of acute kidney injury (AKI) in overweight, obese, and normal body mass index (BMI) patients, and to assess impact of BMI on mortality and chronic kidney disease (CKD) rates. We conducted literature search using online databases to analyze outcomes of BMI. This meta-analysis included 22 studies. Compared to normal BMI, underweight, overweight, or obese patients had higher risk of having AKI. Underweight individuals had 17% lower CKD risk (relative risk [RR]: 0.83, 95% confidence interval [CI]: 0.75, 0.90) while patients that were overweight (RR: 1.15, 95% CI: 1.08, 1.22) and obese (RR: 1.21, 95% CI: 1.10, 1.33) had higher risk of having CKD. Lower than normal BMI was associated with higher mortality risk (RR: 1.58, 95% CI: 1.35, 1.85), while being overweight or obese correlated with the decreased risk of mortality. An increased risk of AKI combined with an increased risk of mortality calls for renal protective strategies in subjects who are underweight at the time of hospital admission.

Effects of sunshine duration on daily outpatient visits for depression in Suzhou, Anhui Province, China.

Previous epidemiological studies have reported seasonal variation patterns of depression symptoms, which may be influenced by bad weather conditions, such as a lack of sunlight. However, evidence on the acute effects of sunshine duration on outpatient visits for depression is limited, especially in developing countries, and the results are inconsistent. We collected daily outpatient visits for depression from the local mental health centre in Suzhou, Anhui Province, China, during 2017-2019. We defined the 5th and 95th sunshine percentiles as short and long sunshine durations, respectively. A quasi-Poisson generalized linear regression model combined with a distributed lag nonlinear model was used to quantitatively assess the effects of short and long sunshine durations on outpatient visits for depression. Stratified analyses were further performed by gender, age and number of visits to identify vulnerable populations. A total of 26,343 depression cases were collected during the study period. An approximate U-shaped exposure-response association was observed between sunshine duration and depression outpatient visits. The cumulative estimated relative risks (RRs) for short and long sunshine durations at lag 0-21 days were 1.53 [95% confidence intervals (CI): 1.14, 2.06] and 1.13 (95% CI: 0.88, 1.44), respectively. Moreover, a short sunshine duration was associated with a greater disease burden than a long sunshine duration, with attributable fractions (AFs) of 16.64% (95% CI: 7.8%, 23.89%) and 2.24% (95% CI: -2.65%, 5.74%), respectively. Subgroup analysis showed that males, people aged less than 45 years and first-visit cases may be more susceptible to a lack of sunlight. For a long sunshine duration, no statistically significant associations were found in any population groups. Our study found that a short sunshine duration was associated with an increased risk of depression. The government, medical institutions, family members and patients themselves should fully recognize the important role of sunlight and take active measures to prevent depression.

An Empirical Study on the Evaluation of Emotional Complexity in Daily Life.

Emotional complexity means diversity, universality, and differentiation of individual emotions. This research consisted of two studies to demonstrate the constitution of the emotional complexity. In Study 1, the participants were asked to use 10 emotional words to record the variation of emotions over 30 days in daily life. In Study 2, the experimental materials were enriched. The participants were required to note the emotions with the Positive and Negative Affect Schedule in a 3-day holiday-all the individuals in the two studies needed to record the most important emotional event. As a result, the youth experienced complex emotions every day. Emotional complexity indicators included covariation index (r), component index (C pc and C unshared), granularity index (G e, G p, and G n), and variability index (V p and V n). A four-factor model reflected a good model fit, with 𝜒2/df = 0.33, CFI = 1.00, TLI = 1.03, RMSEA = 0.000 (0.00, 0.20), SRMR = 0.003, including positive differentiation, covariation of positive affect and negative affect, negative differentiation, and emotional variation. These indicators may reflect the complex experiences in everyday life. The results shed light on the emotional experience that can change greatly within 1 day and on episodes of emotional disruption resulting from an important event coupled with excessive excitement or extreme tension.

Factors associated with mental health outcomes among health care workers in the Fangcang shelter hospital in China.

BACKGROUND: Faced with surging infections and considering that 80% of cases were mild and moderate, the city government transformed stadiums and exhibition centers into the Fangcang shelter hospitals (temporary treatment centers) in Wuhan. AIM: The aims of this study were to evaluate psychological impact on health care workers in the Fangcang shelter hospitals and analyze potential risk factors associated with these symptoms, including PTSS, symptoms of anxiety, depression, insomnia, and perceived stress. METHODS: This cross-sectional study used an online survey to assess mental health problems of 522 health care workers in a Jianghan Fangcang shelter from February 21 to February 28, 2020. RESULTS: Overall, 25.3%, 25.3%, 51.0%, 58.0%, 14.8%, and 39.1% of all participants reported symptoms of posttraumatic stress, anxiety, depression, insomnia, and perceived stress, respectively. Multivariable logistic regression analysis showed that, occupation and technical title were associated with all investigated outcomes. Nurses were more likely to endorse posttraumatic stress symptoms (OR, 4.63; 95% CI, 2.43-8.82; p < .001), anxiety symptom (OR, 4.58; 95% CI, 2.76-7.62; p < .001), depression symptom (OR, 3.45; 95% CI, 2.17-5.64; p < .001). Participants with senior technical title were associated with higher perceived stress and insomnia than other technical title. CONCLUSION: In this survey, participants reported high rates of symptoms of posttraumatic stress, anxiety, depression, insomnia, and perceived stress. Combining with the special environment of the shelter hospitals and the psychological needs, the health care workers should be given more effective interventions to relieve their stress and improve mental symptoms.

Social skill training for children with autistic spectrum disorder on the uncertainty of the disease from mothers / 中国学校卫生

Objective@#To improve the social skills of children with ASD by using Program for the Education and Enrichment of Relational Skills(PEERS ), and to reduce the uncertainty towards ASD and negative emotions for mothers of ASD children.@*Methods@#From September to October 2017, 30 dyads of autistic mother and child were recruited and divided into intervention group and control group (15 mother child dyads each). Based on the content of PEERS social skill, cognitive behavior therapy was delivered in group format, through demonstration, role play and group exercise. At the same time, mother child dyads were trained using parallel social technology. Mothers and children with ASD were investigated using Parents Perception of Uncertainty Scale (PPUS), Patient Health Questionnaire 9 (PHQ-9), Chinese Version of the Beck Depression Inventory II(BDI-Ⅱ-C), Beck Anxiety Inventory (BAI), State Trait Anxiety Inventory(STAI-Form Y), and Autism Behavior Checklist (ABC), Cildhood Autism Rating Scale (CARS), and Social Communication Questionnaire (SCQ).@*Results@#Changes in ASD symptom score in children and emotional score of mothers in the intervention group were less than 0. The total score of mother disease uncertainty(74.93±13.58, 90.40± 9.21 ), ambiguity(31.13±7.07, 38.93±4.73), lack of clarity information(11.93±2.09, 13.80±2.54), unpredictability(9.60±1.99, 12.07±2.89), significantly changed after intervention( t =-3.65, -3.55, -2.20, -2.72, P <0.05).@*Conclusion@#Social PEERS group intervention can enhance the social skills of children with ASD, reduce uncertainty of illness among mother of ASD children. Timely disease related information, guidance for mothers to actively participate in child care and training, might help to reduce cognitive bias, depressive and anxiety symptoms among mothers.

The relationship between stress, resilience, and quality of life in Chinese high school students.

BACKGROUND: Stress is an important factor affecting the dynamic process of resilience. This study aimed to explore the role of stress levels in the relationship between resilience and health consequences by investigating high school students undergoing the National College Entrance Examination (CEE), which often involves intense stressful conditions for students in China, at different stages. METHODS: The CD-RISC [Conner-Davidson Resiliency Scale] and SF-36 [the short form 36 health survey questionnaire, one measurement of the quality of life (QoL)] were used to investigate 435 high school students, including 208 students in grade two (low stress group) and 227 students in grade three (high stress group). RESULTS: This study found that the SF-36 scores under high-stress conditions were significantly lower than those under low-stress conditions, however there were no significant differences in the mental resilience scores. Additionally, under low-stress conditions, mental resilience was found to be significantly correlated with various factors of SF-36, but no significant correlation was observed under high-stress conditions. It was also discovered that stress levels can mediate the relationship between psychological resilience and QoL (the quality of life). CONCLUSIONS: Stress level is an important factor affecting the expression of resilience. This study also discussed the integration of the concept of resilience.

Factors associated with mental health outcomes among patients with COVID-19 treated in the Fangcang shelter hospital in China.

INTRODUCTION: Faced with surging infections and considering that 80% of cases were mild and moderate, the city government transformed stadiums and exhibition centers into the Fangcang shelter hospitals in Wuhan. The aims of this study were to evaluate mental health outcomes among patients with COVID-19 treated in the Fangcang shelter hospitals and analyze potential risk factors associated with these symptoms, including PTSS, symptoms of anxiety, depression, insomnia, and perceived stress. METHOD: This cross-sectional study used an online survey to assess mental health problems of 461 confirmed COVID-19 patients in a Jianghan Fangcang shelter from February 15 to 22, 2020. A multivariable logistic regression analysis was performed to explore potential risk factors. RESULTS: Overall, 25.2%, 50.1%, 54.4%, 10.2%, and 39.7% of all patients reported symptoms of posttraumatic stress, anxiety, depression, insomnia, and perceived stress, respectively. Multivariable logistic regression analysis showed that female sex was associated with all investigated outcomes except insomnia. Patients with lower education level were more likely to endorse anxiety, depression, and higher perceived stress, while patients' family members with other diseases were more likely to endorse severe insomnia. Patients with illness onset to admission less than 7 days were associated with higher perceived stress. DISCUSSION: In this survey study, patients reported high rates of symptoms of posttraumatic stress, anxiety, depression, insomnia, and perceived stress. Combining with the special environment of the shelter hospitals and patient's psychological needs, the health care workers should give more effective interventions to relieve the patients' stress and improve their mental symptoms.

The epidemic characteristics and spatial autocorrelation analysis of hand, foot and mouth disease from 2010 to 2015 in Shantou, Guangdong, China.

BACKGROUND: Hand, foot and mouth disease (HFMD) is the highest incidence of infectious diseases in China. Shantou is one of the most infected cities. Therefore, it is necessary for us to understand the epidemic characteristics and distribution trend of HFMD in Shantou. The purpose of this study is to investigate the spatial epidemiological characteristics of HFMD and analyse its spatial autocorrelation. METHOD: We collated and summarised the data of HFMD in Shantou from 2010 to 2015. SaTScan software and Moran's I were used to analyse the spatial correlation of HFMD, and the results were presented in ArcMap. RESULTS: The distribution of HFMD in Shantou was of a seasonal trend, mainly concentrating during May and June. Children under 5-years-old were the main group of cases of HFMD, accounting for 92.46%. The proportion of infected children, especially those aged zero to 1, was the largest in each year, accounting for 45.62%, meaning that smaller children were more susceptible to HFMD. The number of male patients with HFMD was greater than that of females (1.78:1, male: female). With regard to the potential impact of patients' living style on the incidence rate of HFMD, this study revealed that scattered children were the dominant infected population, accounting for as much 84.49% of cases. The incidence of HFMD was unevenly distributed among streets. The incidence interval of streets was in a range of 13.76/100,000 to 1135.19/100,000. Spatial autocorrelation analysis showed that there was no global spatial correlation in Shantou, except in 2013. The results of local spatial autocorrelation analysis showed that H-H correlation existed in the high incidence local area of Shantou. CONCLUSIONS: The incidence of HFMD across the various streets in Shantou not only varied widely but also represented local autocorrelation. Attention, as well as prevention and control measures, should be focused on those high-incidence areas, such as the Queshi street, Zhuchi street and Xinjin street.

The application of meteorological data and search index data in improving the prediction of HFMD: A study of two cities in Guangdong Province, China.

Hand, foot and mouth disease (HFMD) is a public health issue in China, and its incidence in Guangdong Province is higher than the national average. Previous studies have found climatic factors have an influential role in the transmission of HFMD. Internet search technology has been shown to predict some infectious disease epidemics and is a potential resource in tracking epidemics in countries where the use of Internet search index data is prevalent. This study aims to improve the prediction of HFMD in two Chinese cities, Shantou and Shenzhen in Guangdong Province, applying both meteorological data and Baidu search indices to create a HFMD forecasting model. To this end, the relationship between meteorological factors and HFMD was found to be linear in both cities, while the relationship between search engine data and HFMD was not consistent. The results of our study suggest that using both Internet search and meteorological data can improve the prediction of HFMD incidence. Using comparative analysis of both cities, we posit that improved quality search indices enhance prediction of HFMD.

Cu-Catalyzed carbamoylation versus amination of quinoline N-oxide with formamides.

An efficient, direct carbamoylation and amination of quinoline N-oxides with formamides to access 2-carbamoyl and 2-amino quinolines has been developed through copper-catalyzed C-C and C-N bond formations via cross-dehydrogenative coupling reactions. The reaction proceeds smoothly over a broad range of substrates with excellent functional group tolerance under mild conditions. Mechanistic studies suggest that the reaction is initiated by formamide radical or decarbonylative aminyl radical formation in the presence of TBHP, according to the different substituent on the N atom of formamide.

A Randomized Controlled Trial of Mindfulness-Based Cognitive Therapy for College Students With ADHD.

OBJECTIVE: Between 2% and 8% of college students meet criteria for ADHD, with increased incidence in recent decades. There are very few clinical trials conducted on the meaningful intervention of ADHD in college. Mindfulness-based cognitive therapy (MBCT) effectively treats college students with ADHD and could be more feasibly applied in college mental health clinics. METHOD: Fifty-four undergraduates with ADHD between ages 19 and 24 were randomized to receive either MBCT or wait-list (WL) during a 6-week intervention phase. ADHD symptoms, neuropsychological performance, and related outcomes were assessed at pre-treatment, post-treatment, and 3-month follow-up. RESULTS: Participants receiving MBCT group showed greater treatment response rates (57%-71% vs. 23%-31%) and experience less anxiety and depression, and greater levels of mindfulness; MBCT participants show greater improvement on neuropsychological performance. CONCLUSION: MBCT may be a useful intervention for college students with ADHD, improving participants' ADHD symptoms, mindfulness, and sustained attention.

Sleep Patterns and Academic Performance During Preparation for College Entrance Exam in Chinese Adolescents.

BACKGROUND: Deficient sleep is linked to detrimental outcomes in health and school performance for adolescents. This study characterized sleep patterns in Chinese adolescents preparing for the College Entrance Exam (CEE) and evaluated the association between sleep patterns, self-rated academic performance, and the CEE scores. METHODS: A sample of 481 Chinese adolescents in 12th grade (ages 16-19 years) completed questionnaires about sleep patterns, academic performance, academic stress, and sociodemographic factors 4-6 weeks before the CEE in June 2013. The CEE scores for each student also were obtained. RESULTS: A total of 21% of the students had bedtimes after 12:00 am, 78.3% had sleep latency longer than 30 minutes, 14.6% had wake time earlier than 6:00 am, and the vast majority (94.4%) had sleep duration less than 8 hours. After adjusting for selected confounders such as academic stress, prolonged sleep latency was associated with poorer self-reported academic performance, and late bedtime was associated with higher CEE score. CONCLUSIONS: Our findings highlight the complex association between sleep and academic performance. Assessing and monitoring sleep patterns in adolescents during periods of high academic demand and stress may yield important recommendations for their health and safety as well as establishing optimal sleep and study habits.

Sleep Disturbances and Associated Factors in Chinese Children with Autism Spectrum Disorder: A Retrospective and Cross-Sectional Study.

Sleep disturbances in children with autism spectrum disorder (ASD) exist worldwide, but little is known about this issue in non-Western cultures. This study aimed to characterize sleep disturbances in Chinese children with ASD and to examine associated sociodemographic factors and emotional/behavioral problems. Parents of 60 Chinese children with ASD (aged 6-17 years) from Shenzhen, China completed the Children's Sleep Habits Questionnaire (CSHQ), and the Strengths and Difficulties Questionnaire (SDQ). Sleep disturbances were severe and common, with rates of 70.0% for overall disturbances and 15.0% (daytime sleepiness) to 40.0% (sleep duration) for specific domains. The severity and rate of sleep disturbances were higher compared to previous studies in typically developing children from the same region of China and American children with ASD, respectively. Further, there were significant correlations between most CSHQ and SDQ domains. Female gender, older parental age, higher hyperactivity, and poorer prosocial behavior were associated with increased overall sleep disturbances.

[Anisakis simplex larvae: infection status in marine fishes for sale in Shantou].

OBJECTIVE: To investigate the infection status of Anisakis simplex larvae in marine fishes for sale in Shantou. METHODS: Marine fishes were randomly collected from markets in Shantou City from February to December 2013, and then classified. The viscera and muscle of each fish were carefully dissected and thoroughly examined for anisakids. The larvae were examined under a light microscope. The infection rate and intensity of Anisakis simplex larvae were calculated. RESULTS: A total of 382 fish specimens belonging to 52 species were examined. 42 out of 52 species (80.8%) were found infected by A. simplex larvae. The overall infection rate reached 47.4% (181/382), and average 5.5 larvae parasitized per infected fish (995/181). The survival rate of larvae was 100%. The highest infection rate observed was 100% in Scomber australasicus (4/4), Trachurus japonicus (9/9), Decapterus maruadsi (8/8), Lutjanus lutjanus (9/9), Argyrosomus argentatus (4/4), Nibea albiflora (4/4), Nemipterus bathybius (12/12), Trachinocephalus myops (7/7) and Mene maculata (9/9), followed by 16/18 in Pneumatophorus japonicus, 6/7 in Lutjanus ophuysenii and 5/6 in Lutjanus fulvus. A. simplex larvae were not detected in 10 fish species, namely, Megalaspis cordyla, Lutjanus argentimaculatus, Lutjanus fulviflamma, Acanthopagrus australis, Acanthopagrus latus, Plectorhinchus nigrus, Dentex tumifrons, Psenopsis anomala, Scatophagus argus, and Seriola lalandi. The infection intensity was the highest in Lutjanus fulvus (21.0 per fish), followed by Trachinocephalus myops (16.7 per fish), Saurida filamentosa (14.0 per fish) and Mene maculate (10.1 per fish). The lowest infection intensity was found in Rastrelliger kanagurta, Kaiwarinus equula, Atule mate, Lutjanus russellii, Plectorhinchus cinctus, Priacanthus tayenus, Branchiostegus argentatus, Branchiostegus albus, Sphyraena pinguis, Formio niger, Trachinotus blochii, Siganus fuscescens and Choerodon azurio (less than 2 per fish). The highest infection rate (34.3%, 131/382) was found in the mesentery. The infection intensity was highest in pyloric appendage (3.5 per fish). A. simplex larvae were not found in muscle. The highest infection rate (60.2%, 74/123) was found in fishes with body weight of 100-200 g. The infection intensity was highest in fish with body weight of 301-400 g (7.8 per fish). CONCLUSION: The infection rate of A. simplex larvae is high in marine fishes from Shantou markets.

Sleep patterns and sleep disturbances among Chinese school-aged children: prevalence and associated factors.

OBJECTIVE: The study aimed to (1) characterize sleep patterns and sleep disturbances among Chinese school-aged children, (2) determine the prevalence of their short sleep duration and sleep disturbances based on clinical cutoffs, and (3) examine possible factors (socio-demographic factors and emotional/behavioral problems) that are associated with sleep disturbances. METHODS: A large representative sample of 912 children aged 6-14years was recruited from Shenzhen, China. Their parents completed the Children's Sleep Habits Questionnaire (CSHQ) and the Strengths and Difficulties Questionnaire (SDQ). RESULTS: The mean bedtime was 9:45pm (SD=1h 11min), mean wake-up time was 7:03am (SD=31min), mean sleep duration was 9h 14min (SD=46min), and 23.8% of the children had sleep duration <9h. Overall, 69.3% of the children suffered from global sleep disturbances (CSHQ total score >41). Bedtime resistance (22.9%), sleep anxiety (22.1%), sleep duration (21%) and daytime sleepiness (20%) were the most prevalent sleep disturbances; followed by sleep disordered breathing (12.1%), parasomnias (9.4%), sleep onset delay (6.9%), and night waking (5.2%). The prevalence of specific sleep disturbances ranged from 3.2% (falling asleep while watching television) to 81.9% (awakening by others in the morning). Correlations between most domains of sleep disturbances and emotional/behavioral problems were statistically significant (p<0.05 or p<0.01). Hierarchical multiple regression analysis revealed that gender (ß=0.10, p<0.01), school grade (ß=-0.09, p<0.05), co-sleeping (ß=0.25, p<0.01), emotional symptoms (ß=0.24, p<0.01), conduct problems (ß=0.09, p<0.05), and hyperactivity (ß=0.17, p<0.01) accounted for significant variance in CSHQ total score. CONCLUSIONS: Short sleep duration and sleep disturbances are prevalent among Chinese school-aged children. Sleep disturbances are associated with gender, school grade, co-sleeping, emotional symptoms, conduct problems, and hyperactivity.

Efficacy of Yiqiyangxin Chinese medicine compound combined with cognitive therapy in the treatment of generalized anxiety disorders.

OBJECTIVE: To observe the clinical efficacy of Yiqiyangxin Chinese medicine compound combined with cognitive therapy on generalized anxiety disorders. METHODS: A total of 202 generalized anxiety disorders patients were randomly allocated to a control condition (Paroxetine combined with cognitive therapy) or a treatment condition (Yiqiyangxin Chinese medicine compound combined with cognitive therapy). Subsequently, scores of Hamilton Anxiety Scale (HAMA), Zung Self-rating Anxiety Scale (SAS) and blood routine, urine routine, liver function, renal function, electrocardiogram were detected before treatment, 3 months, 6 months after treatment and 6 months after medicine withdrawal, respectively. RESULTS: HAMA and SAS scores were significantly reduced in two groups (P<0.001) after treatment, but the differences in HAMA and SAS scores, apparent effect and effectiveness were not significant (P>0.05). HAMA and SAS scores were significantly increased in two groups (P<0.05) after medicine withdrawal, and there were significant differences in HAMA and SAS scores, recurrent disease and adverse reaction (P<0.001). The incidence of recurrent disease and adverse reaction in treatment group was low. Both two groups showed no apparent abnormality in blood routine, urine routine, liver and renal function, and electrocardiogram. CONCLUSIONS: Yiqiyangxin Chinese medicine compound combined with cognitive therapy can significantly reduce the recurrence after medicine withdrawal and is effective on generalized anxiety disorders. Furthermore, the incidence of adverse reactions is low. The treatment program is worthy clinic application in the further.

[Relationships between psychosocial factors and work-related musculoskeletal disorders in coal miners].

OBJECTIVE: To estimate the associations of psychosocial factors with work-related musculoskeletal disorders (WMSDs), providing scientific evidence for targeted strategies for the prevention of WMSDs in Chinese coal miners. METHODS: A total of 500 coal miners were consecutively enrolled to this cross-sectional study. The prevalence of WMSDs was assessed using the Standardized Nordic Questionnaire. Logistic regression analyses were conducted to estimate the associations between psychosocial factors and WMSDs. RESULTS: Among coal miners, of 277 coal miners, 61% self-reported WMSDs in a 12-month period. Especially, back pain was the most frequent musculoskeletal symptom. WMSDs were statistically correlated with high job demands (OR = 1.3, 95%CI: 1.3 ∼ 3.5), low job control (OR = 1.6, 95%CI: 1.0 ∼ 2.4), low level of interpersonal relations (OR = 1.9, 95%CI: 1.2 ∼ 3.0) and low job satisfaction (OR = 1.6, 95%CI: 1.0 ∼ 2.4). CONCLUSION: The results of this study demonstrate psychosocial factors were associated with WMSDs among coal miners, and psychosocial factors be considered for the prevention of WMSDs.

Prevalence of low back pain and associated occupational factors among Chinese coal miners.

BACKGROUND: Very few studies have evaluated the association between occupational factors and low back pain (LBP) among miners. The epidemiological data on LBP in Chinese miners are limited. The aim of this study was to measure the prevalence of low back pain in Chinese coal miners and to investigate the role of occupational factors. METHODS: A cross-sectional survey was conducted to examine 1573 coal miners in northern China. The prevalence of LBP over a 12-month period was assessed using the Nordic Musculoskeletal Questionnaire. Odds ratios were calculated to examine the association between the prevalence of LBP over a 12-month period and occupational factors using logistic regression. RESULTS: Among the coal miners, 64.9% self-reported LBP in a 12-month period. Occupational factors associated with LBP were identified, including tasks with a high degree of repetitiveness (OR 1.3, 95%CI 1.0-1.6), tasks characterized by a high level of physical demand (OR 1.4, 95% CI 1.1-1.8), posture requiring extreme bending (OR 1.6, 95% CI 1.2-1.7) and insufficient recovery time (OR 1.4, 95% CI 1.0-1.8). CONCLUSION: Low back pain is common among Chinese miners. There were strong associations with occupational factors.
