ABSTRACT
Objective To investigate the prevalence of comorbid depression and anxiety and to evaluate the effect of psychological interventions among schistosomiasis patients in China, so as to provide insights into improvements of psychological health among schistosomiasis patients. Methods Publications pertaining to comorbid depression and anxiety and psychological interventions among Chinese schistosomiasis patients were retrieved in electronic databases, including CNKI, Wanfang Data, PubMed, Web of Science, and Embase. The prevalence of comorbidity, psychological interventions, and scores for the Self-Rating Depression Scale (SDS) and Self-Rating Anxiety Scale (SAS) before and after psychological interventions among Chinese schistosomiasis patients were extracted. The prevalence of comorbid depression and anxiety was investigated among Chinese schistosomiasis patients using a meta-analysis, and the effect of psychological interventions for depression and anxiety was evaluated. Results A total of 231 publications were retrieved, and 14 publications that met the inclusion and exclusion criteria were included in the final analysis, including 2 English publications and 12 Chinese publications. Meta-analysis showed that the prevalence rates of comorbid depression and anxiety were 61% [95% confidential interval (CI): (48%, 72%)] and 64% [95% CI: (42%, 81%)] among Chinese schistosomiasis patients. Both the SDS [1.45 points, 95% CI: (1.30, 1.60) points] and SAS scores [2.21 points, 95% CI: (2.05, 2.38) points] reduced among Chinese schistosomiasis patients after psychological interventions than before psychological interventions, and the SDS [−0.47 points, 95% CI: (−6.90, −0.25) points] and SAS scores [−1.30 points, 95% CI: (−1.52, −1.09) points] reduced among Chinese schistosomiasis patients in the case group than in the control group. Conclusions The comorbid anxiety and depression are common among Chinese schistosomiasis patients, and conventional psychological interventions facilitate the improvements of anxiety and depression among schistosomiasis patients.
ABSTRACT
Objective:To discover the epidemiological characteristics and clinical manifestations of Nontyphoidal Salmonella(NTS) infection in children suffering from diarrhea in Guangzhou, and to provide references for the prevention and treatment of salmonella infection. Methods:A total of 570 diarrhea children and 296 non-diarrhea controls were collected with stratified sampling from three districts of Guangzhou Women and Children′s Medical Center from January 2019 to December 2019. Through bacterial culture, corresponding colonies were selected and Salmonella diagnostic serum was applied for preliminary serum diagnosis, and then systemic biochemical method was adopted for diagnosis. A structured questionnaire was conducted to record the demographic information and clinical symptoms from each subject. Results:The detection rate of NTS was 6.67% (38/570 cases, 95% CI: 4.90%-9.02%) in children with diarrhea, and 1.01% (3/296 cases, 95% CI: 0.34%-2.93%) in children without diarrhea. There were statistically differences in NTS detection rate between children with diarrhea and the control ( χ2=13.805, P<0.05, OR=6.976, 95% CI: 2.135-22.796). There were no significant differences in NTS detection rate between male and female children with diarrhea ( χ2=0.395, P>0.05, OR=1.254, 95% CI: 0.619-2.541). The detection rate of NTS was 5.30% (22/416 cases, 95% CI: 3.52%-7.88%) in children younger than 2 years old, and was 10.40% (16/154 cases, 95% CI: 6.50%-15.21%) in children over 2 years old. There were statistically differences ( χ2=4.700, P<0.05, OR=2.076, 95% CI: 1.060-4.068) between the younger and the older groups.The detection rate of NTS was 5.40% (25/460 cases, 95% CI: 3.70%-7.89%) for children with diarrhea in outpatient department and 11.80% (13/110 cases, 95% CI: 7.04 %-19.18%) for children with diarrhea in inpatient department, with statistically significant differences ( χ2=5.813, P<0.05, OR=2.332, 95% CI: 1.152-4.721). The detection rate of NTS diarrhea in children was 4.60% (10/217 cases, 95% CI: 2.52%-8.28%) in spring, 8.50% (12/141 cases, 95% CI: 4.93%-14.29%) in summer, 9.60% (15/144 cases, 95% CI: 6.41%-16.48%) in autumn and 1.50% (1/168 cases, 95% CI: 0.11%-3.30%) in winter, respectively, with statistically differences among the four seasons( χ2=9.404, P<0.05). There were significant differences in most common clinical symptoms of fever, vomiting, abdominal pain, bloody stool and pasty stool between NTS positive and negative children(all P<0.05). Salmonella enteritis is the main type, and Salmonella typhimurium is the second type. Conclusions:NTS is one of the most important bacterial pathogens and leads to diarrhea in children in Guangzhou city, without differences in gender.Children over 2 years old are more likely to suffer from NTS infection.High incidence is in autumn.The most common clinical symptoms include fever, vomiting, abdominal pain, bloody stool and pasty stool. Salmonella enteritis is the main type, and Salmonella typhimurium is the second type.Laboratory tests can provide references for the diagnosis and treatment of NTS-related diarrhea.
ABSTRACT
Objective To evaluate potential protective effects of inhaled budesonide on bronchopulmonary dysplasia (BPD) in premature infants and its impact on the intelligence development at 1 year of age. Methods A total of 82 preterm infants admitted to the neonatal intensive care center from January 2017 to January 2018 were selected as research subjects. The enrolled subjects were divided into a study group (Budesonide) and a control group (saline) by random number table method, with 41 cases in each group. The incidence of BPD, mortality, hospitalization time, time of withdrawal and oxygenation, and complications were compared between the two groups. The patients were regularly followed up to 1 year old after discharge. The physical growth and Gesell intelligence development of the two groups were compared. Results The incidence of BPD in the study group was significantly lower than that in the control group, and the difference was statistically significant (P<0.05). There was no significant difference in mortality between the two groups. The hospitalization time, weaning and oxygenation time, and 1-week re-intubation rate in the study group were significantly lower than those in the control group (P<0.05). There was no significant difference between the two groups in the incidence of adverse reactions and physical growth at 1 year old and Gesell intelligence evaluation. Conclusion Budesonide aerosol inhalation reduced the incidence of BPD in premature infants, shortened hospitalization and weaning time, and there were no near-term and long-term adverse reactions.
ABSTRACT
Objective:To systematically analyze the clinical features of severe fever with thrombocytopenia syndrome (SFTS) and to provide evidence for the prevention and treatment of SFTS.Methods:Relevant studies of SFTS from six databases, including China National Knowledge Infrastructure, Wanfang Database, Chongqing VIP, PubMed, Cochrane Library and Embase from January 2009 to May 2019 were systematically searched and identified. The literatures were screened and the data of patients′ epidemiology, clinical manifestations, laboratory examinations and prognosis were obtained. Revman 5.2 software was used for meta analysis.Results:Sixty-eight Chinese literatures and fourteen English literatures encompassing 6 780 patients with SFTS were included in the final analysis. Of these patients, 845 cases (12.46%) died. SFTS mostly occurred in mountainous and hilly areas, and farmers (3 637 cases) were the usual victims. The onset season was mostly in summer and the peak was from May to August each year. There were 1 434 patients had a clear history of tick bites, and 21 cases were human-to-human transmitted.There were 6 071 cases (89.54%) presented with fever, 5 407 cases (79.75%) presented with fatigue, 3 140 cases (46.31%) presented with muscle soreness, and 2 300 cases (33.92%) presented with chills.Using random effects model for meta analysis, the levels of creatine kinase (CK) (mean difference ( MD)=500.40, 95% confidence interval ( CI) 380.51-620.28, P<0.01) and lactic acid dehydrogenase (LDH)( MD=442.81, 95% CI 152.85-732.78, P=0.003) in severe patients were both higher than those in mild patients, and the difference were both statistically significant. The risk of death increased in patients aged>60 years( MD=8.19, 95% CI 4.03-12.36, P<0.01). The levels of CK( MD=530.92, 95% CI 29.27-1 032.56, P=0.040), LDH( MD=609.28, 95% CI 80.25-1 138.31, P=0.020), urea nitrogen ( MD=4.67, 95% CI 3.05-6.30, P<0.01) and creatinine ( MD=43.05, 95% CI 23.49-62.62, P<0.01) of patients in the death group were all higher than those in the survival group. The differences were all statistically significant. Conclusions:During the course of SFTS, the patients may show impaired blood system, heart, liver and kidney functions with high mortality. Clinicians should timely monitor the changes of blood routine, myocardial enzyme spectrum, liver and kidney functions and other indicators, so as to find cardiovascular and other system complications as early as possible. Timely treatment could not only reduce liver, heart and other organ injuries, but also reduce mortality.
ABSTRACT
Objective@#To investigate the molecular epidemiological characteristics of Human Calicivirus (HuCV) infection among children less than 5 years in Kunming city, Yunnan province, it might be provide effective evident for prevention and control the diarrhea related with HuCV infection.@*Methods@#Four sentinel hospitals were recruited in the study from Kunming city, Yunnan province, 850 diarrhea cases and 170 non-diarrhea subject were recruited in this study from 2014 to 2015. RT-PCR was performed to screen HuCV infection, and gene sequencing was used to ensure positive infection subtypes and genotypes.@*Results@#The positive rate of HuCV was higher in children with diarrhea than in non-diarrhea children (11.5%, 98/85; 4.7%, 8/170, χ2=7.083, P=0.008), and the positive rate of Norovirus (NoV) GII was higher in non-diarrhea children were (11.1%, 94/85; 4.7%, 8/170, χ2=6.353, P=0.012). There was no significant difference in the positive rate of NoV GI (0.1%, 1/850; 0.0%, 0/170, P=0.833) and Sappovirus (0.4%, 3/850; 0.0%, 0/170, P=0.578) in diarrhea children and non-diarrhea children. GII.P4 (10%, n=102) was the most important genotype of NoV GII detected in diarrhea and non-diarrhea individuals. Despite no significant difference in Norovirus GII infection between different age groups (χ2=0.038, P=0.846) and sex(χ2=0.620, P=0.733), infection rate of NoV GII varied with season (χ2=9.867, P=0.020), having close relationship with diarrhea in autumn (15.6%), primarily caused by GII.4 and GII.12 genotype (χ2=8.881, P=0.031; χ2=7.917, P=0.039).@*Conclusions@#NoV GII diarrhea had higher epidemic rate, which was caused by multiple genotypes, GII.P4 was a dominant genotype, and was a major pathogenic agent of diarrhea in infants f in Kunming city.
ABSTRACT
Objective@#To analyze the infectious status and etiological characteristics of rotavirus A (RVA) from children less than five years old in the Kunming city of Yunnan province from July 2014 to June 2015, to provide basic data and methodological references for the disease surveillance, and controling outbreak cases investigations as well as vaccine research and development.@*Methods@#Stool samples were collected from 1 121 diarrhea cases and 319 healthy controls in four sentinel hospitals and transported to laboratory. Two-step reverse transcriptional polymerase chain reaction (RT-PCR) was used to detect the presence of RVA in each stool specimen. Suspicious positive specimens of gel electrophoresis was further sequenced to make definite diagnosis of RVA infection. Each RVA positive stool specimen was confirmed with sequencing which was conducted the semi-nested multiplex RT-PCR to detect six G genotypes and six P genotypes.@*Results@#Total 244 samples from the 1 212 diarrhea patients were detected positive for RVA and the total positive rate was 21.8%. G typing of group A rotavirus mainly showed G9(66.4%, n=156), G3(18.7%, n=44), G1(8.9%, n=21)and G8(1.7%, n=4). P typing mainly showed P[8](92.8%, n=218)and P[4](4.7%, n=11); G/P combination genotypes were composed mainly of G9P[8](57.0%, n=134), G3P[8](18.3%, n=43) and G1P[8](8.9%, n=21). The detection rate of RVA in diarrhea patients had obvious seasonal distribution (χ2=46.3, P<0.001), with the prevalent peak in winter (31.2%), and the seasonal distribution of G9P[8](χ2=27.3, P<0.001), G1P[8](χ2=8.2, P<0.039)and G3P[8](χ2=10.2, P<0.042) had strong seasonal pattern with a peak in winter equally. In the subjects under five years, the detection rate of G9P[8](14.9%, 2.9%, χ2=18.1, P<0.001) and G3P[8](4.4%, 0.5%, χ2=5.6, P<0.018) from diarrhea cases were higher than that of in healthy controls, respectively.@*Conclusion@#There existed rather high infection rate of RVA in acute diarrhea cases in Yunnan province, which can be divided into a variety of genotypes, G9P[8]was the dominant genotype.
ABSTRACT
Objective To study the application of autoregressive integrated moving average(ARIMA)model to predict the monthly reported malaria cases in China,so as to provide a reference for prevention and control of malaria. Methods SPSS 24.0 software was used to construct the ARIMA models based on the monthly reported malaria cases of the time series of 2006-2015 and 2011-2015,respectively. The data of malaria cases from January to December,2016 were used as validation data to compare the accuracy of the two ARIMA models. Results The models of the monthly reported cases of malaria in China were ARIMA(2,1,1)(1,1,0)12 and ARIMA(1,0,0)(1,1,0)12 respectively. The comparison between the predictions of the two models and actual situation of malaria cases showed that the ARIMA model based on the data of 2011-2015 had a higher ac-curacy of forecasting than the model based on the data of 2006-2015 had. Conclusion The establishment and prediction of ARIMA model is a dynamic process,which needs to be adjusted unceasingly according to the accumulated data,and in addi-tion,the major changes of epidemic characteristics of infectious diseases must be considered.
