  • Rapid Assessment of Health Needs after Disasters: A Systematic Review

    Objective To provide references for fast assessment after disasters in China by assessing articles on fast assessment of health needs after disasters. Methods We systematically searched CNKI, VIP, CBM, and PubMed from their establishments to Jan. 2011. The main results of the eligible articles were described. Results A total of 65 articles were included, of which introductions for methodology and cross-sectional studies accounted for 52.31% and 44.62%, respectively. Articles which focused on natural disasters made up 86.15% of the total. Post-disaster rapid assessment should include seismic death estimate and on-site public health assessment which contained the public health status in affected areas, health coping capacity, health condition of victims and health needs. Rapid assessment of seismic death mainly used methods based on GIS and ANN model. On-site public health assessment mainly used epidemiological field investigation. Questionnaires, interviews and surveillance of diseases were adopted. Conclusion Rapid post-disaster health needs assessment is one of the most important tasks after disasters, and the current rapid assessment methods need to be refined and improved.

  • Establishment of normal reference value range of specific thyroid function in pregnant women with Beckman reagent in Chengdu area

    ObjectiveTo establish a normal reference value range of specific thyroid function in pregnant women corresponding to Beckman reagent in Chengdu.MethodsWe randomly selected 120 non-pregnant women and 445 pregnant women who underwent routine examinations at the First Affiliated Hospital of Chengdu Medical College from November 2016 to June 2017; tested for free triiodothyronine (FT3), free thyroxine (FT4), and thyroid stimulating hormone (TSH) in serum; used SPSS 24.0 to calculate the bilateral limit of each index (Section 2.5, 97. 5 Quot); established the normal range of Beckman reagent.ResultsThe reference ranges of FT3, FT4, and TSH in the first, second, and third trimester of pregnancy were 4.41–6.33, 4.17–6.12, and 3.86–6.39 pmol/L; 7.64–14.63, 6.62–13.69, and 6.62–12.51 pmol/L; 0.21–3.62, 0.16–4.35, and 0.89–4.88 mU/L; respectively. There was no significant difference in serum TSH between the first and second trimester (P>0.05), and neither between the first and second trimesters and the controls in serum FT3 (P>0.05). The differences in serum FT3, FT4, and TSH among the rest of trimesters, and between each trimester and the normal control group were statistically significant (P<0.05). There was a significant correlation between TSH and FT4 in the early and middle stages of pregnancy (r=–0.277, –0.392, P<0.01).ConclusionThe reference value of FT3, FT4, and TSH in pregnant women with Beckman reagent was significantly different from that in non-pregnant women.

  • Population Attributed Risk Proportion Associated with Poor Self-Rated Health in the Elderly: A Systematic Review

    Objective To systematically review the evidence of the factors associated with self-rated health (SRH) and estimating the population attributable risk proportion (PARP) of interests in the elderly. Methods MEDLINE, EMbase, CBM, CNKI, VIP and WanFang Data were searched (from January 1960 to April 2011) for relevant literature. The combined effect on each factor associated with poor SRH was expressed as RR or OR (95%CI). The contribution of each factor to poor SRH in the elderly population was estimated with PARP. Meta-analysis was performed using RevMan 5.1 software. Results Twelve studies involving a total of 35 349 participants aged 60 or above were eligible in this systematic review. Ten studies were conducted in China and the rest two studies were from the USA and Brazil. Of them, only one was prospective cohort study and 11 studies were cross-sectional. The results of meta-analysis showed that the main factors associated with poor SRH in the elderly were dependency, diabetes and coronary heart disease with the corresponding OR and 95%CI as 12.10 (6.31, 23.20), 6.49 (3.21, 13.09) and 5.60 (1.07, 29.42), respectively. However, the top three factors contributing to poor SRH in the elderly population were coronary heart disease, having illness half one year ago and chronic disorders with the corresponding PARP as 53.91%, 52.56%, and 50.09%, respectively. It was not possible to perform sub-group analysis because of the limited quantity of studies on each factor associated with poor SRH. Conclusion Based on the current available evidence, it appears that chronic disorders are closely related to poor SRH and contribute most in the elderly population. However, due to the limitation of the included predominantly cross sectional studies which are not enough for causal argument, it is insufficient to determine the association of many factors with poor SRH. Further high-quality prospective cohort studies are needed.

  • Efficacy and safety of non-pharmacological interventions for sleep disturbance in dementia: a systematic review

    ObjectiveTo systematically review the efficacy and safety of non-pharmacological interventions for sleep disturbance in dementia, and to provide evidence for clinical practice.MethodsDatabases including CNKI, WanFang Data, VIP, PubMed, EMbase and The Cochrane Library were searched to collect randomized controlled trials (RCTs) on non-pharmacological interventions for sleep disturbance in dementia from inception to May 2020. Two reviewers independently screened literature, extracted data, and assessed risk of bias of included studies. Meta-analysis was then performed using RevMan 5.3 software.ResultsA total of 9 RCTs were included, involving 720 patients. Light therapy was the most commonly used treatment, followed by special activity and sleep education program. The results of meta-analysis showed that compared with the control intervention, light therapy could improve sleep efficiency (MD=2.21, 95%CI 1.09 to 3.33, P=0.0001) and the night-time sleep (MD=14.27, 95%CI 5.01 to 23.53, P=0.003) of patients with dementia in the community and nursing institutions, special activity could increase the night-time sleep (MD=29.74, 95%CI 20.44 to 39.04, P<0.00001), and sleep education program could also improve sleep efficiency (MD=6.19, 95%CI 5.22 to 7.16, P<0.00001) and night-time sleep (MD=33.95, 95%CI 25.40 to 42.50, P<0.00001). In addition, it was superior to obtain 120 or 60 minutes of light exposure than 30 minutes to improve the quality of sleep (RR=−2.62, 95%CI −3.56 to −1.68, P<0.001) and reduce daytime sleep (RR=−4.75, 95%CI −5.71 to −3.42, P<0.001). However, there was significant difference in incidence of adverse reactions between groups of 120 minutes and 30 minutes of light exposure (RR=2.57, 95%CI 1.44 to 4.58, P=0.001).ConclusionsThe current evidence shows that non-pharmacological intervention can improve sleep efficiency and night-time sleep in patients with dementia. Due to limited quantity and quality of the included studies, more high quality studies are required to verify above conclusions.

  • Meta-analysis of the difference of peripheral inflammatory factors in Alzheimer’s disease and vascular dementia

    ObjectiveTo systematically review the data of peripheral inflammatory markers in patients with Alzheimer’s disease (AD) and vascular dementia (VaD) to further indicate pathogenesis and antidiastole.MethodsPubMed, EMbase, The Cochrane Library, CNKI, WanFang Data and VIP databases were electronically searched to collect studies on peripheral inflammatory markers in patients with AD and VaD from inception to July 2020. Two reviewers independently screened literature, extracted data, and assessed risk of bias of included studies, and meta-analysis was performed by using Stata 15.1SE software.ResultsA total of 30 studies involving 2 377 patients were included. The results of meta-analysis showed that the IL-6 level was higher in VaD group than that in AD group (SMD=−0.477, 95%CI −0.944 to −0.009, P=0.046). However, there were no statistical difference in peripheral IL-1β (SMD=−0.034, 95%CI −0.325 to 0.257, P=0.818), TNF-α (SMD=0.409, 95%CI −0.152 to 0.970, P=0.153) or CRP (SMD=0.277, 95%CI −0.228 to 0.782, P=0.282) levels.ConclusionsThese findings suggest that IL-6 may be sensitive markers to distinguish AD from VaD. Due to limited quality and quantity of the included studies, more high-quality studies are required to verify the conclusions.

  • Research on the Relationship between Mental Health Status and Perceived Social Support among Middle School Students from Wenchuan Earthquake Hit Area

    Objective To investigate the mental health status, perceived social support, as well as the relationship between them among middle school students in Wenchuan Earthquake region, so as to provide references for the relevant department to formulate appropriate strategies and intervention measures. Methods A cluster sampling method was adopted to select all 1698 students (excluded the students in Grade 3) as the research subjects from three middle schools in the disaster regions. All students were investigated with self-designed basic information questionnaire, Symptom CheckList 90 (SCL-90) and Perceived Social Support Scale (PSSS) through self-administered questionnaire. Results The overall positive rate on the SCL-90 was 46.3% among 1690 students, of whom 66.6% had mild psychological problems and 26.5% had moderate to severe psychological problems. The positive rate on the SCL-90 and the score for each factor of SCL-90 were statistically higher in the female students than male students (Plt;0.05). Compared with the senior middle school students, the score on the phobic anxiety subscale of the SCL-90 was statistically higher in the junior middle school students (Plt;0.05), while the score on the obsessive-compulsive subscale was otherwise statistically lower (Plt;0.05). With the exception of the hostility subscale, the score on each subscale of the SCL-90 in the urban students was statistically lower than the rural students (Plt;0.05). The median score on the perceived social support subscale was 60.00, with significant differences between the students of different sexes and grades (Plt;0.05). The overall score on the perceived social support subscale was negatively correlated with the SCL-90 score (r= –0.261, Plt;0.05). The score was negatively correlated with the SCL-90 score in the students regarding different sexes, grades and living areas prior to the earthquake (Plt;0.05). Conclusion The middle school students in the disaster regions have prominent psychological problems; perceived social support is helpful to promote the development of their mental health. In conducting psychological intervention, the difference of individuals’ mental health among different student groups should be concerned, so as to carry out targeted counseling and education.
