RESUMO

Objective: To assess the antidiarrheal effects of Terfezia claveryi methanolic extract against Escherichia coli, Salmonella typhimurium, Shigella flexneri, and Giardia lamblia. Methods: Antibacterial effects of the Terfezia claveryi methanolic extract were carried out by determining the minimum inhibitory concentration (MIC) and minimum bactericidal concentration through micro broth dilution technique. Furthermore, reactive oxygen species production and protein leakage were evaluated. To evaluate the in vitro anti-giardial effects of Terfezia claveryi methanolic extract, Giardia lamblia WB (ATCC® 30957) trophozoites were treated with various concentrations of Terfezia claveryi methanolic extract for 10-360 min. In addition, the plasma membrane permeability of trophozoites treated with Terfezia claveryi methanolic extract was determined. The cytotoxicity effects of Terfezia claveryi methanolic extract against normal (HEK293T) and cancer (MCF-7) cells were also assessed using the MTT assay. Results: The MIC and minimum bactericidal concentration of Terfezia claveryi methanolic extract against bacterial strains were in the range of 0.52-1.04 and 1.04-2.08 mg/mL, respectively. The results revealed that reactive oxygen species production and protein leakage were significantly increased after the bacteria were treated with the Terfezia claveryi methanolic extract, especially at 1/3 and 1/2 MICs (P<0.001). Furthermore, Terfezia claveryi methanolic extract decreased the viability of Giardia lamblia trophozoites in a dose-dependent manner. Terfezia claveryi methanolic extract at 1, 2, and 4 mg/mL resulted in 100% mortality in Giardia lamblia trophozoites after 360, 240, and 120 min, respectively. Moreover, Terfezia claveryi methanolic extract altered the permeability of plasma membrane of Giardia lamblia trophozoites by increasing the concentration. MTT assay revealed that the 50% cytotoxic concentrations values for HEK293T and MCF-7 cells were 4.32 mg/mL and 6.40 mg/mL, respectively, indicating that Terfezia claveryi methanolic extract had greater cytotoxicity against cancer cells than normal cells. Conclusions: Terfezia claveryi methanolic extract had potent in vitro antibacterial and anti-parasitic effects on Escherichia coli, Salmonella typhimurium, Shigella flexneri, and Giardia lamblia by affecting cell membrane permeability and reactive oxygen species generation with no significant cytotoxicity on normal cells.

RESUMO

In order to meet the needs of prevention and control of intestinal infectious diseases, a comprehensive surveillance for diarrheal diseases has been innovated and explored in Shanghai since 2012. The surveillance has extensive distribution of sentinel hospitals, systematic sampling, multi-pathogen collection, and hospital information system (HIS) as the basis, which has achieved “One system for surveillance of multiple diseases and one sample for detection of multiple pathogens". Continual active surveillance for the whole population has been conducted, covering demography, clinical information, epidemiology, pathogen detection, and drug sensitivity test for diarrhea cases. The surveillance has obtained preliminary achievements as follows. First, diarrheal diseases and their periodic changes have been characterized, in which the most prevalent pathogen of diarrhea is determined to be norovirus in Shanghai. Second, some rare pathogens and serotypes have been identified that may provide clues to the sources of outbreaks. Third, it facilitates the information sharing between public health institutions and clinical institutions, and provides scientific evidence for clinical diagnosis and treatment. In the future, Shanghai diarrhea comprehensive surveillance will be improved for expanding range and depth of surveillance, artificial intelligence assisted diagnosis and treatment, early warning of outbreaks, prediction of epidemic trends, and application of new detection technologies.

RESUMO

Infectious diarrhea is an important public health problem, which has a significant impact on global disease burden. Under the background of climate change, rainstorms increase and floods occur frequently. Most studies show that the incidences of infectious diarrhea disease increase significantly after rainstorm and flood events. However, there is a lack of systematic summary on the path of rainstorm and flood events affecting the incidence of infectious diarrhea, including the key links and mechanisms underlying environmental-social interaction. This study comprehensively combed the literature from environmental factors, socio-economic and cultural factors, and population and individual susceptibility factors. The potential mechanisms of infectious diarrhea caused by rainstorm and flood events were discussed from the aspects of spreading of pathogens, affecting sanitation facilities and (or) drinking water treatment infrastructure, the regulatory role of individual and behavioral factors, and long-term effects. Based on the "pressure-state-response" model, a social driving process model of rainstorm and flood leading to incidence of infectious diarrhea was constructed. This model could provide reference for future quantitative modeling and other research directions. It is helpful to guide the public health departments to accurately identify factors affecting the incidence of infectious diarrhea after rainstorm and flood, so as to take targeted intervention measures.

RESUMO

Objective:To explore the lag effect and correlation between daily average temperature and the incidence of other infectious diarrhea in Hebei Province.Methods:The data of meteorological factors (including temperature and average daily temperature) and the daily incidence of other infectious diarrhea in Zhangjiakou City, Chengde City, Tangshan City, Qinhuangdao City, Baoding City, Langfang City, Cangzhou City, Shijiazhuang City, Hengshui City, Xingtai City, and Handan City in Hebei Province from 2017 to 2020 were collected. Eleven prefecture-level cities were divided into four regions, including east, north, middle and south regions. Distributed lag non-linear model was applied to examine the non-linear associations and the lag effect of daily mean temperature on daily incidence of other infectious diarrhea. Meanwhile, the cold and hot effects were used to estinuate the lag-response relationship on the incidence of other infectious diarrhea.Results:A total of 231 008 cases of other infectious diarrhea were reported in Hebei Province. The seasonal distribution was obvious, showing a bimodal distribution of large peaks in summer and small peaks in winter. An inverse S-shaped association between average daily temperature and cumulative risk ratio ( RR) of other infectious diarrhea was observed in Hebei Province. Both high temperature (higher than 27.50 ℃) and low temperature (less than 13.67 ℃) could increase the risk of other infectious diarrhea. When the temperature was lower than 13.00 ℃, the lag time and RR had a U-shaped association (lag four to seven days, 23 to 30 days). Meanwhile, when it was higher than 13.00 ℃, it had an inverted U-shaped association (lag 5 to 21 days). A comparison of four regions of Hebei Province showed that the lag time from south to north was extended from six days to 30 days at low temperature effects with temperature P5=-7.24 ℃. When the temperature getting hot ( P95=28.25 ℃), the risk occurred at lag 0 days, and the lag time gradually got short from north to south. Thus, the high temperature effect reached maximum quickly with a relative short duration. Conclusions:The inverse S-shaped non-linear association between daily average temperature and the incidence of other infectious diarrhea in Hebei Province is observed. Both low temperature and high temperature are associated with increased risk of other infectious diarrhea. But the impact of low temperature is more notable, which has a relative long duration.

RESUMO

Objective@#To analyze the pathogenic spectrum of infectious diarrhea among children in Zhengzhou City in 2020, so as to provide insights into the management of childhood infectious diarrhea.@*Methods@#A total of 230 stool samples were collected from children with diarrhea in the Diarrhea Clinic of Zhengzhou Municipal Children's Hospital in 2020. Diarrheagenic Escherichia coli, Salmonella, Shigella, Vibrio parahaemolyticus, Campylobacter and Aeromonas were isolated. Salmonella was typed using pulsed-field gel electrophoresis ( PFGE ) and antimicrobial resistance was tested in Salmonella. The main types and drug resistance of pathogens were descriptively analyzed.@*Results@#The 230 children with diarrhea included 152 males and 78 females, with a male to female ratio of 1.95∶1. There were 173 cases at ages of 3 years and below ( 75.22% ), and 82 cases seen between June and August ( 35.65% ). A total of 71 pathogenic bacteria strains were isolated, with a detection rate of 30.87%. Salmonella was the most frequently isolated pathogen ( 35 strains, 15.22% prevalence ), following by diarrheagenic E. coli ( 20 strains, 8.70% ). Eleven serotypes of Salmonella were identified, which mainly included S. enteritidis and S. typhimurium. PFGE typing revealed 25 band patterns of Salmonella, with a similarity ranging from 11.85% to 100%. Salmonella were sensitive to imipenem, meropenem, polymyxin B and amikacin and highly resistant to streptomycin ( 85.71% ), ampicillin ( 80.00% ) and sulfaisoxazole ( 80.00% ). A 82.86% proportion of multi-drug resistance was detected in the 29 Salmonella strains. @*Conclusions@# A wide range of pathogenic bacteria were detected from the childhood infectious diarrhea in Zhengzhou City in 2020, which mainly included Salmonella and diarrheagenic E. coli. A high polymorphism level was seen in PFGE fingerprints of Salmonella, which presented high-level resistance to antimicrobial agents.

RESUMO

Objective To investigate the etiology and epidemic characteristics of infectious diarrhea in children in Suzhou, and to provide a basis for accurate prevention and control. Methods Active surveillance of infectious diarrhea pathogens was carried out in a national sentinel surveillance hospital in Suzhou from 2018 to 2020. Epidemiological investigation was completed and stool samples were collected. All samples were detected and classified for 5 viruses and 6 types of bacteria. Results A total of 999 cases of infectious diarrhea were included, the detection rate of pathogen was 36.34%, virus was 31.41%, bacteria was 6.31%, and multi-pathogen mixed infection was 4.8%. The top three pathogens were rotavirus (17.92%), norovirus (12.51%) and Salmonella (3.4%). Both rotavirus diarrhea and norovirus diarrhea occurred most frequently in children aged 7-24 months, with peak incidence in winter and early spring. There was no obvious seasonal and age distribution of bacterial diarrhea. The multi-pathogen mixed infection was mainly virus-virus. G9[P]8 was the dominant genotype of rotavirus, while type 2 was the dominant type of norovirus in the cases of infectious diarrhea. Conclusion Infectious diarrhea in children under 5 years old in Suzhou area from 2018 to 2020 is mainly caused by viruses, among which rotavirus and norovirus are the dominant pathogens. Viral diarrhea has obvious population distribution and seasonal characteristics. The dominant pathogens of bacterial diarrhea are Salmonella and diarrheagenic Escherichia coli.

RESUMO

ObjectiveTo investigate the prevalence and epidemiological characteristics of norovirus in adult cases with infectious diarrhea in Putuo District of Shanghai, and provide scientific evidence for the prevention and control of infectious diarrhea caused by norovirus. MethodsFecal samples, clinical information and epidemiological data were collected from January 2013 through December 2019 in surveillance hospitals in Putuo District of Shanghai. Norovirus was examined by real-time fluorescent quantitative reverse transcription polymerase chain reaction (rRT-PCR). ResultsIn 1 389 adult cases with infectious diarrhea, norovirus positive rate was 25.41%, which was significantly higher in male (27.16%) than female (23.89%). Furthermore, in 353 cases positive for norovirus, GⅡ group was the most common (77.98%).The positive rate was highest in the cases aged 30-44 years. Spring, autumn and winter were the seasons with higher incidence of norovirus (September to May). The norovirus-infected cases had more nausea, vomiting, hyperactivity of bowel sounds, and watery stool, compared to the negative cases (P<0.05). ConclusionThe detection rate of norovirus remains high in adult cases with infectious diarrhea in Putuo District of Shanghai, of which GII is predominant. Seasonality may be spring, autumn and winter. Therefore, it warrants the countermeasures, such as surveillance and health education, for prevention and control of norovirus in susceptible population during epidemic seasons.

RESUMO

Objective To understand the epidemiological characteristics of norovirus infectious diarrhea in Pudong New Area of Shanghai, and to provide reference for prevention and control of diarrhea caused by norovirus. Methods Epidemiological data and stool samples from diarrhea cases of 15 hospitals in 2015-2019 years were collected. The two subtypes of norovirus G I and G II were detected by RT-PCR and analyzed. Results A total of 9 397 diarrhea samples were collected in 2015-2019 years, and 1 938 positive norovirus samples were detected, with a positive rate of 20.62%. The majority of serotypes were GII (88.60%). Diarrhea caused by norovirus occurs all year round, with high incidence season in 2-3and 10-12 months every year. There was no significant difference in the positive rate of norovirus between different sexes(χ2=2.611,P=0.106). The positive rate of the 15-64 year old group was higher than that of the 0-14 year old group and the 65 year old and above group(χ2=153.634,P<0.001). The highest positive rate was for cadres /worker/ business services / teachers / medical staff / drivers. The positive rate of norovirus in diarrhea cases with vomiting was significantly higher than that in patients without vomiting. Conclusions Diarrhea caused by norovirus is related to season, age and occupation. Because there is no effective antiviral drugs and vaccine prevention, continuous monitoring should be carried out and targeted preventive measures should be carried out according to epidemiological characteristics.

RESUMO

Objective@#To identify the etiology and source of infection in a diarrhea outbreak in Yunnan in May 2017 and to provide the evidence for formulating prevention and control measures.@*Methods@#Epidemiological investigation was carried out on the epidemic situation of diarrhea in the village of Lvchun County in Yunnan Province, the field sampling, laboratory testing and data analysis were also performed.@*Results@#Among the 44 patients, 11 of the 13 samples were positive for rotavirus nucleic acid in group A, and the positive rate was 84.62%. The survey showed that the water supply pipe was damaged and polluted by human and livestock manure and domestic sewage. The trend of the damaged water pipe was basically the same as the case distribution, and the rainfall was significantly related to the number of the disease.@*Conclusions@#This event was an outbreak of diarrhea caused by group A rotavirus. The direct pollution of drinking water caused by rainfall may be the risk factor of this outbreak. The health management of rural drinking water should be strengthened and the health knowledge and education of preventing intestinal infectious diseases should be promoted.

RESUMO

Objective@#To find out the source and the epidemic pattern of norovirus outbreak in July, 2016 to June, 2017 in Guangzhou.@*Methods@#The stool samples and clinical information of diarrhea cases were collected by the sentinel hospitals and CDCs; a real-time RT-PCR method was used to detect the norovirus nucleic acids from the samples, the positive ones were amplified and sequenced; the partial sequences of norovirus were aligned by an online BLAST alignment, and a phylogenetic tree was constructed by a neighbor-joining method .@*Results@#A total of 854 cases with infectious diarrhea were reported by Guangzhou diarrhea surveillance network from July, 2016 to June, 2017; the gender ratio (male versus female) was 1∶0.67; 78.33% of the cases were preschool children under the age of 7 years. Totally 220 samples were detected norovirus G II+ (25.76%, including 5 double-positive samples with G I+ ). GII.Pe-GII.4.Sydney_2012 was the prevalent genotype in the second half of 2016 (94.64%), which was replaced by GII.P16-GII.2 in the first half of 2017 (67.65%). Since September 2016, the reported number of norovirus-caused diarrhea epidemic was increased gradually; the peak of epidemic curve emerged in February to March of 2017, and the number started to decrease since April. In May to June there were only 2-3 epidemics reported monthly. All the endemics from September to November 2016 were caused by genotype GII.Pe-GII.4.Sydney_2012; the endemics from December 2016 to April 2017 were mainly caused by genotype GII.P16-GII.2. Some samples from kitchen workers and babysitters were detected GII+ , which was consistent with the result of the cases′ samples.@*Conclusions@#It was the first time that the novel GII.P16-GII.2 recombinant strain outbroke occurred in Guangzhou City and homology analysis also suggested that GII.P16-GII.2 was the main source of those epidemics in 2016 -2017 winter and spring season. Furthermore, The kitchen workers and babysitters may have played an important role in the spread of norovirus.

RESUMO

To systematically review the efficacy and safety of Huoxiang Zhengqi Pills combined with Western medicine in the treatment of acute gastroenteritis. Four Chinese databases( CNKI,VIP,Wan Fang,Sino Med) and three English databases( Cochrane Library,Medline,EMbase) were systematically and comprehensively searched from the database establishment to April 2019 to collect the randomized controlled trials( RCTs) about the treatment of acute gastroenteritis with Huoxiang Zhengqi Pills combined with Western medicine. Two investigators independently performed literature screening,data extraction and bias risk assessment. Rev Man 5. 3 software was used for data analysis. A total of 316 articles were retrieved and finally 44 studies were included in this study,involving 4153 patients. The overall quality of the included studies was generally low. Meta-analysis results showed that in the total clinical effective rate,Huoxiang Zhengqi Pills combined with conventional treatment or norfloxacin tablets was superior to conventional treatment or norfloxacin tablets alone. In terms of the time for improving clinical symptoms,Huoxiang Zhengqi Pills combined with conventional treatment or norfloxacin tablets could better relieve fever than conventional treatment or norfloxacin tablets alone. In terms of incidence of adverse reactions,there was no statistical difference between Huoxiang Zhengqi Pills combined with conventional treatment and conventional treatment alone. Other outcome measures were affected by various factors( such as inclusion of only 1 study or excessive heterogeneity among studies) and could not be concluded. Due to the limitations of the quality and quantity of included studies,this conclusion still needs to be verified by more high quality researches.
