ObjectiveTo systematically review the prevalence and risk factors of the chronic post-cesarean section pain (CPCSP). MethodsPubMed, EMbase, The Cochrane Library, CINAHL, PsycInfo, CBM, WanFang Data, VIP, and CNKI databases were electronically searched to collect studies on the prevalence and risk factors of CPCSP from inception to August 2021. Two reviewers independently screened literature, extracted data, and assessed the risk of bias of included studies. Meta-analysis was then performed using Stata 15.1 software. ResultsA total of 43 studies involving 12 435 participants were included. The results of meta-analysis showed that the prevalence of CPCSP for 2 to 5 months, 6 to 11 months, and at least 12 months were 19% (95%CI 15% to 23%), 13% (95%CI 9% to 17%), and 8% (95%CI 6% to 10%), respectively. The risk factors included preoperative pain present elsewhere, postoperative severe acute pain, low abdominal transverse incision, non-intrathecal administration of morphine, preoperative anxiety, postpartum depression, etc. ConclusionsThe current evidence shows that the overall prevalence of CPCSP is high. Preoperative pain presents elsewhere, postoperative severe acute pain, low abdominal transverse incision, non-intrathecal administration of morphine, preoperative anxiety and postpartum depression may increase the risk of CPCSP.
Objective To understand the prevalence of overweight and obesity and its influence factors in Zhuhai inhabitants. Methods Applying multi-stage cluster random sampling in the three administrative areas of Zhuhai including Xiangzhou, Doumen and Jinwan, A questionnaire-based survey was performed in conjunction of the measurement of height and weight among 961 inhabitants aged 15-69 years. In addition, a multivariate unconditional logistic regression model was employed to analyze the influence factors of overweight and obesity. Results The prevalence and standardized rates of overweight and obesity in the study population were 18.1%, 17.6%, 6.6%, 6.5%, respectively. The standardized rates of overweight and obesity in male and female were 18.4%, 5.8%, 16.5%, 7.2%, respectively. Age, drinking, smoking and regional difference were identified as the 4 risk factors of overweight and obesity, their OR values being 1.028, 1.683, 0.677, 1.404, Plt;0.05, respectively. Conclusion The prevalence of overweight and obesity in Zhuhai’s inhabitants was over the average level of Chinese residents, and overweight and obesity has become a major risk factor influencing the health of Zhuhai’s inhabitants. In view of the influence factors of overweight and obesity, timely and effective prevention and control measures should be taken.
Objective To study the prevalence of snoring in adults aged over 35 yrs in Kelamayi city of Xinjiang province, and screen the snoring associated factors.Methods 2600 subjects( age≥35 yrs) were enrolled from a random sample of the population living in 5 streets, two districts in Kelamayi city. All subjects were required to answer questions about their snoring by himself or bed partner at home. The questionnaire included items concerning snoring, daytime sleepness ( Epworth sleep scale, ESS) , smoking and drinking habits, while height, weight, neck circumference, abdominal circumference, waistline, and hip circumference were meatured. The subjects were assigned to a high risk group and a low risk group according to the questionaire of scoring. Results 2590 subjects had completed the questionnaire and 2513 ( 97. 0% )were eligble for evaluation. The cases of ever snoring was 1312 ( 52. 2% ) , among which moderate to severe snoring accounted for 38. 9% . Before the age of 60 yrs, the risk of snoring increased with age, and higher in males than females( 61. 7% vs. 45. 1% ) . The prevalence of snoring increased with neck circumference( P lt;0. 05) . The body mass index ( BMI) [ ( 28. 2 ±3. 6) kg/m2 vs. ( 25. 1 ±3. 9) kg/m2 ] , neck circumference [ ( 37. 7 ±3. 6) cmvs. ( 35. 6 ±3. 6) cm] , abdominal circumference [ ( 96. 9 ±13. 6) cm vs. ( 88. 7 ±11. 1) cm] , waistline [ ( 92. 2 ±9. 8) cm vs. ( 84. 7 ±10. 2) cm] , hip circumference [ ( 102. 9 ±9. 6) cm vs.( 96. 4 ±9. 3) cm] , proportionlity of waistline to hip circumference ( 0. 90 ±0. 07 vs. 0. 88 ±0. 08) , systolic blood pressure [ ( 132. 0 ±17. 5) mm Hg vs. ( 125. 6 ±16. 8) mm Hg] , and diastolic blood pressure [ ( 83. 3 ±12. 8) mm Hg vs. ( 78. 3 ±12. 6) mm Hg] were significantly different bettween the high and the low risk groups ( P lt; 0. 01) . Logistic regression analysis revealed that age ( OR = 1. 519) , BMI ( OR =2. 549) , neck circumference (OR = 2. 473) , smoking (OR = 2. 765) , ESS(OR = 2. 575) , and postmenopause( OR=1. 806) were main risk factors for snoring( P lt; 0. 05) . Conclusions The prevalence of snoring in adults over 35 yrs is high in Kelamayi city. The high risk factors for snoring are age, BMI, neck circumference, smoking, ESS, and post-menopause.
ObjectiveTo analyze the trend of hospital infection, so as to provide a scientific basis for hospital infection prevention and control. MethodsFrom 2011 to 2013, according to the criteria of diagnosis of nosocomial infections set up by the Ministry of Health, the prevalence rates of nosocomial infections in patients who were hospitalized on the survey day were investigated by the combination of bedside investigation and medical records checking. ResultsThe incidence rates of nosocomial infections from 2011 to 2013 were 2.99%, 2.31% and 1.95%, respectively, presenting a downward trend. The rate of hospital infection was the highest in comprehensive Intensive Care Unit, and the main infection site was the lower respiratory tract. Gram-negative bacteria were the main pathogens causing hospital infections, including Klebliella pnermoniae, Pseudomonas aeruginosa, Staphylococcus aureus, Acinetobacter baumannii and Escherichia coli. The utilization rates of antibacterial agents in these three years were respectively 39.84%, 34.58% and 34.22%. ConclusionTargeted surveillance and management of key departments and sites should be strengthened. It is necessary to strengthen the surveillance and management of antibiotics, raise the submission rate of pathogens, and use antibiotics appropriately.
Objective To investigate the clinical effectiveness and adverse event of preventive medicine for severe acute respiratory syndrome (SARS), and provide clinical data for designing prospective clinical trial. Method Retrospective study on medical staffs, that were exposed to SARS patients, was conducted in two main SARS designated hospitals to obtain information such as SARS exposure risk and preventive measures (medical and others). According to the type of preventive medicine, they were assigned to earthworm’s nucleases and protease (ENP) group, interferon group and blank control group respectively. Exposure risk, suspected sub-clinical infection rate and adverse event rate were compared between the three groups. Results Non-medical preventive measures used in each group were consistent, but the exposure intensity to risk factors between groups was statistically different, which biased the evaluation of clinical effectiveness of preventive medicine. The rate of suspected sub-clinical infection in earthworm’s nucleases and protease (ENP) group, interferon group and control group were 4.5%, 4.5%, and 9.9% (Pgt;0.05), respectively; and adverse event rate were 19.6%, 13.6% (Pgt;0.05), and 0%, respectively. Conclusions Suspected sub2clinical infection rate in ENP group, interferon (INF) group were lower than that in control group, which indicated that these two medicines might be effective in preventing SARS. Adverse event rate in ENP group was similar to that of interferon group, and the symptoms were mild in both groups, which was in accordance with the result of in vitro experiments. ENP spray is a kind of biological preparation; further purification may reduce its adverse event rate. However, because there had excessive confounding factors, especially because of the unequal of exposure risk between three groups, the results of this study can only provide insights to design prospective clinical trial in the future.
ObjectiveTo systematically review the prevalence of cognitive impairment in patients with sarcopenia. MethodsThe PubMed, EMbase, Web of Science, Cochrane Library, CBM, CNKI, VIP and WanFang Data databases were electronically searched to collect studies related to the objectives from inception to December 10, 2022. Two reviewers independently screened literature, extracted data and assessed the risk of bias of the included studies. Meta-analysis was then performed by using Stata 14.0 software. ResultsA total of 27 studies were included. The overall prevalence rate of cognitive impairment in sarcopenia was 36.1% (95%CI 29.4% to 42.8%). Subgroup analysis showed that the prevalence in Europe was higher than that in other areas. The prevalence of nursing home residents was highest. ConclusionCurrent evidence shows that the prevalence of cognitive impairment in patients with sarcopenia is high. Due to the limited quality and quantity of the included studies, more high quality studies are needed to verify the above conclusion.
ObjectiveTo investigate the prevalence of subclinical hypothyroidism (SCH) in health check-up population of West China Hospital of Sichuan University from 2011 to 2012 and to discuss the relationship between SCH and metabolic syndrome (MS). MethodsThose who received thyroid function tests and health examination in the West China Hospital of Sichuan University from 2011 to 2012 were enrolled in the study. The data of medical history, blood pressure, height, weight, thyroid function, TG, HDL-C, FPG were collected. All data were analyzed by SPSS 18.0 software. ResultsA total of 11 976 persons (7 488 male and 4 488 female) received thyroid function tests. There were 1 820 persons (884 males and 936 females, 15.20%) who suffered from SCH. The SCH prevalence was significantly higher in females (20.86%) than that in males (11.81%) (P < 0.01). The people over 60 years old had the highest SCH prevalence. There were 1 145 persons (1 005 males and 140 females) suffered from MS among all 11 976 persons. The MS prevalence was significantly higher in males (13.42%) than that in females (3.12%) (P < 0.01). The SCH prevalence of the MS group was higher, which in the health group was lower (P < 0.01). The TSH level in the MS group was higher, while it was lower in the health group. ConclusionThe prevalence of SCH is higher in health check-up population; and SCH apparently increases the risk of morbidity of MS.
Objective To study the prevalence of combined pulmonary fibrosis and emphysema (CPFE) in a community-based lung cancer screening program in Shanghai. Methods From June 2018 to July 2019, eligible participants who were assessed through a high-risk lung cancer questionnaire in Xuhui, Shanghai underwent low-dose computed tomography of the lungs. The suspected CPFE patients were invited to provide medical history and blood for analysis, and received high-resolution CT (HRCT) scanning for confirmation. Results Of the 15 cases of suspected CPFE from a total of 4478 participants in which 1704 males and 2774 females, 4 declined further examination and 11 received further examine. Eight subjects were confirmed as CPFE, and all were male, of whom two were ex-smokers and six were active smokers. These CPFE patients had cough, chest tightness and dyspnea. There were 3 cases of centrilobular emphysema, 2 cases of paraseptal emphysema, 1 case of panlobular emphysema and 2 cases of mixed emphysema. There were 2 cases of usual interstitial pneumonia, 3 cases of non-specific interstitial pneumonia, 2 cases of airspace enlargement with fibrosis and 1 case of unclassifiable smoking-related interstitial fibrosis. The KBILD scores were 61.7±7.5 and mMRC scores were 1.5±0.8. Serum Krebs von den Lungen-6 concentration was (380.75±212.05)U/mL. Lung function test showed normal or mild restrictive ventilatory function, and mild-moderate impairment in diffusion capacity. Conclusions The prevalence of CPFE is 1.79‰ in a community-based lung cancer screening population, and is 4.69‰ in male lung cancer screening population.
ObjectiveTo investigate the prevalence and risk factors of chronic obstructive pulmonary disease (COPD) in urban and rural male residents of Chengdu city. MethodsA cross-sectional survey about the incidence of COPD using cluster random sampling methods was carried out from February to December 2010 among male residents aged 40 to 70 years in four communities in Chengdu city, which was conducted by applying questionnaire survey, physical examination, portable spirometry, etc. Data was analyzed by using SPSS 18.0 software, and the risk factors were also analyzed by using the multivariate logistic methods. ResultsA total of 631 male residents were included, 301 urban and 330 rural. The results showed that: after population standardization, among male residents aged 40 to 70 years in four communities in Chengdu city, the overall prevalence of COPD was 7.95%, and the prevalence was 12.07% in rural area and 7.05% in urban area (P < 0.001). The results of multivariate logistic regression analysis showed that area, age, BMI and smoking volume were the main risk factors of COPD among male. ConclusionThe prevalence of COPD in Chengdu city is relatively higher, which is much higher in rural area than that in urban area. The risk factors are various, and thus comprehensive prevention and treatment of COPD should be emphasized.
Objective To understand the current rate of nosocomial infection and its changing trend in a grade A comprehensive hospital in 10 years, and to provide scientific basis for the monitoring, control and management of nosocomial infection. Methods Using the method of cross-sectional survey, the inpatients in Mianyang Central Hospital from 2011 to 2020 were selected for bedside survey, and the questionnaire was filled in after review of medical records. The data of cross-sectional survey of nosocomial infection were collected, and the infection-related data of nosocomial and community-acquired infection of patients in each department were statistically analyzed. Results A total of 19 595 cases were investigated. The prevalence rate of nosocomial infection was 3.79%, and the the case prevalence rate of nosocomial infection was 4.04%. The prevalence of community-acquired infection was 33.44%, and the case prevalence rate of community-acquired infection was 35.30%. The departments with higher prevalence rate in nosocomial infection were intensive care unit, neurosurgery, cardiothoracic surgery and hematology. The departments with high prevalence rate in the community-acquired infection were burn department, pediatrics department, neonatology department, respiratory medicine department and pediatric intensive care unit. The most common site of nosocomial infection was lower respiratory tract infection, followed by upper respiratory tract sensation, urinary tract, abdominal tissue and blood. The main pathogens of nosocomial infections were Escherichia coli, Klebsiella pneumoniae, Acinetobacter baumannii, Staphylococcus aureus, and Pseudomonas aeruginosa. The utilization rate of antibacterial drugs was 42.93%. There was a downward trend in prophylactic drug use, mainly one drug combination, and the proportion of combination drug decreased.Conclusion Through the investigation, it can be seen that the key points of nosocomial infection management and prevention and control should be lower respiratory tract infection, postoperative surgical infection, multi-drug resistant bacteria management and rational use of antibiotics.
