Efficacy of a Nutritional Cream Intervention to Treat Depression in Rescuers:A Randomized Controlled Trial

Objective To explore the effectiveness of a nutritional intervention in rescuers who screened positive for depression.Methods A randomized controlled trial design was employed.From June to August,2022,4,460 rescuers were screened using the Self-Rating Depression Scale(SDS),and 1,615 positive cases were identified.Thirty-one volunteers were recruited and randomly divided into a nutritional intervention group and a control group.The intervention group received health education and nutritional intervention(a compound paste therapy primarily composed of red roses and Seville orange flowers),while the control group received psychological education.SDS scores were assessed before and after the intervention.Results There was a statistically significant decline in SDS scores in the nutritional intervention group after the intervention(P<0.05).Furthermore,the SDS scores of the intervention group were significantly lower than those of the control group,both before and after the intervention(P<0.05).No severe adverse reactions were observed during safety evaluation.Conclusion The nutritional intervention effectively reduced the depression scores in rescuers.Early nutritional intervention is recommended for rescuers who initially screen positive for depression.

Analysis of Factors Influencing Insomnia and Construction of a Prediction Model:A Cross-sectional Survey on Rescuers

Objective To determine the factors influencing insomnia and construct early insomnia warning tools for rescuers to informbest practices for early screening and intervention.Methods Cluster sampling was used to conduct a cross-sectional survey of 1,133 rescuers from one unit in Beijing,China.Logistic regression modeling and R software were used to analyze insomniarelated factors and construct a PRISM model,respectively.Results The positive rate of insomnia among rescuers was 2.74%.Accounting for participants’age,education,systolic pressure,smoking,per capita family monthly income,psychological resilience,and cognitive emotion regulation,logistic regression analysis revealed that,compared with families with an average monthly income less than 3,000 yuan,the odds ratio(OR)values and the[95%confidence interval(CI)]for participants of the following categories were as follows:average monthly family income greater than 5,000 yuan:2.998(1.307–6.879),smoking:4.124(1.954–8.706),and psychological resilience:0.960(0.933–0.988).The ROC curve area of the PRISM model(AUC)=0.7650,specificity=0.7169,and sensitivity=0.7419.Conclusion Insomnia was related to the participants’per capita family monthly income,smoking habits,and psychological resilience on rescue workers.The PRISM model’s good diagnostic value advises its use to screen rescuer early sleep quality.Further,advisable interventions to optimize sleep quality and battle effectiveness include psychological resilience training and smoking cessation.

Establishment of the Psychometric Properties of a Disaster Resilience Measuring Tool for Healthcare Rescuers in China:A Cross-Sectional Study

The aim of this study was to test the validity and reliability of a tool for measuring the disaster resilience of healthcare disaster rescuers.A cross-sectional study involving 936 healthcare disaster rescuers of the Sichuan Disaster Response Team was conducted to establish the psychometric properties of the disaster resilience measuring tool(DRMT).Item analysis,exploratory factor analysis,confirmatory factor analysis,and correlation analysis were adopted to analyze the data.Item analysis showed that all but three items had the critical ratio over 3,which indicates adequate discriminability for inclusion in the measuring tool.The exploratory factor analysis showed that 65.93%of the total variance was explained by four factors—self-efficacy,social support,positive growth,and altruism.The confirmatory factor analysis showed goodness of fit for the four-factor model:CMIN/DF(2.846),GFI(0.916≥0.90),CFI(0.949≥0.90),AGFI(0.891≥0.80),and RMSEA(0.063≤0.08).Criterion validity demonstrated significant associations of the DRMT and the Connor-Davidson Resilience Scale(P<0.01,r=0.566).Convergent validity was established by correlation with stress(P<0.05,r=-0.095),depression(P<0.01,r=-0.127),posttraumatic stress disorder-PCL-C(P<0.05,r=-0.100),compassion satisfaction(P<0.01,r=0.536),and burnout(P<0.01,r=-0.330).The DRMT demonstrated adequate internal consistency(Cronbach’s alpha>0.84)and stability over the two-week study period(intraclass correlation coefficient>0.85),and a cut-off point of 61 was suggested.The disaster resilience measuring tool has satisfactory psychometric properties and is a valid,reliable,and valuable instrument for assessing disaster resilience in healthcare rescue workers.The scale needs to be tested further among other populations and those from other cultures.

Subclinical high altitude pulmonary edema: A clinical observation of 12 cases in Yushu

During the Yushu Earthquake on April 14,2010,a high incidence of acute high altitude illness was observed in the mountain rescuers,and 0.73 % of these patients suffered from high altitude pulmonary edema,of which 12 patients developed subclinical pulmonary edema and concomitantly contracted acute mountain sickness. Symptoms and signs were atypically high heart rate with high respiratory rate,striking cyanosis,and significantly low oxygen saturation,whereas no moist rates were heard on auscultation,and Chest X-ray showed peripheral with a patchy distribution of mottled infiltrations in one or both lung fields. We believe that subclinical high altitude pulmonary edema is an earliest stage of pulmonary edema at high altitude. The possible pathogenesis and the diagnosis were discussed.

A Rescuer in the Nucleus:Sno-lncRNA SLERT Found Crucial for Nucleolus Function in Humans

In our conversation with Prof.CHEN Lingling on the"dark mat ter"in the genome,namely the non-coding RNAs,we got to know two classes of long non-coding RNAs(lncRNAs)in close association with Prader-Willi syndrome(PWS).Each with a snoRNA cap on its either end,they fall in the sno-lncRNA family,a group of lncRNAs identified by CHEN’s group in their earlier research.Here we are meeting another member of the family,SLERT,a rescuer
