Methods: Totally, 29 201 cases registered from 2010 to 2015 in Iranian Fars province were selected, and the endemic values of cutaneous leishmaniasis were determined by retrospective clusters derived from spatiotemporal permutation modeling on a time-series design. The accuracy of the values was assessed using receiver operating characteristic(ROC) curve. SPSS version 22, Arc GIS, and ITSM 2002 software tools were used for analysis. Results: Nine statistically significant retrospective clusters(P<0.05) resulted in finding seven significant and accurate endemic values(P<0.1). These valid endemic scores were generalized to the other 18 cities based on 6 different climates in the province. Conclusions: Retrospectively detected clusters with the help of ROC curve analysis could help determine cutaneous leishmaniasis endemic values which are essential for future prediction and prevention policies in the area.展开更多

HPV16 DNA was detected by polymerase chain reaction(PCR) using HPV16 type-specific primers in 296 pelvic lymphnodes which were from 17 cases of cervical cancer.RESULTS The viral load of HPV16 DNA showed statisticallysignificant differences between tumors with a diameter of < 4cm and ≥ 4 cm (P < 0.05). Seven of 17 cervical cancer cases hadHPV16 DNA positive lymph nodes, designated as the positivegroup, while the remaining 10 without positive lymph nodes wasdesignated the negative group. The average load of HPV16 DNAshowed no significant difference between the 2 groups (P > 0.05).The load of HPV16 in the primary lesion was not associated withthat in the lymph nodes. There were 38 HPV16 DNA positivenodes in the total 296 nodes. The rate of positivity of HPV16 DNAin lymph nodes showed statistically significant differences inconsideration of maximum tumor diameter, tumor differentiation,histologic type, depth of myometial infiltration and the metastaticstatus of the nodes, respectively (P < 0.05).CONCLUSION Viral load of HPV16 in the primary cancer focuscorrelated with the quantity of tumor cells in the primary focusbut not with the existence of HPV DNA positive lymph nodes.Detection of HPV DNA may help to find the early metastases thatcannot be evaluated histopathologically, but the prognostic valueof HPV positive lymph nodes needs further examination.展开更多

However, if compliance is negatively influenced by more frequent dosages, this might hamper the effect of the treatments. Therefore, we have studied whether the numbers of daily dosages influence the compliance with prescribed flucloxacillin regimens. Design: A prospective interview study of patients with different dosing regimens of flucloxacillin. Setting: In the study, 200 patients with different dosing regimens of flucloxacillin underwent structured telephone interviews in order to reveal their compliance with the medication. Of these, 13 were prescribed twice-daily doses, 163 three times daily and 24 patients four times daily regimens. Results: There were no statistically significant differences between missed doses and prescribed numbers of daily doses. There was, however, a significant difference in the number of daily doses and experiences associated with the medication. Conclusions: This study shows that patients comply well with regimens of up to four daily doses of flucloxacillin, despite experiencing increasing difficulties with regimens of more frequent dosages.展开更多

Methods A total of 452 patients with common HFMD were randomly assigned to receive Western medicine alone (n=220) or combined with TCM (Reduning or Xiyanping injections) (n=232). The primary outcome was the incidence rate of rash/herpes disappearance within 5 days, while secondary outcomes included the incidence rate for fever, cough, lethargy, agitation, and vomiting clearance within 5 days. Results The rash/herpes disappearance rate was 45.5% (100/220) in Western medicine therapy group, and 67.2% (156/232) in TCM and Western medicine combined therapy group, with significant difference (P<0.001). Moreover, TCM remarkably increased the incidence rate of secondary disappearance, which was 56.4%in Western medicine therapy group and 71.4%in TCM and Western medicine combined therapy group (P=0.001). No drug-related adverse events were observed. Conclusions It’s suggested that the integrative TCM and Western medicine therapy achieved a better therapeutic efficacy. TCM may become an important complementary therapy on relieving the symptoms of HFMD.展开更多

Methods: ...Objective: To determine whether permutation scan statistics was more efficient in finding prospective spatial-temporal outbreaks for cutaneous leishmaniasis(CL) or for malaria in Fars province, Iran in 2016. Methods: Using time-series data including 29 177 CL cases recorded during 2010-2015 and 357 malaria cases recorded during 2010-2015, CL and malaria cases were predicted in 2016. Predicted cases were used to verify if they followed uniform distribution over time and space using space-time analysis. To testify the uniformity of distributions, permutation scan statistics was applied prospectively to detect statistically significant and non-significant outbreaks. Finally, the findings were compared to determine whether permutation scan statistics worked better for CL or for malaria in the area. Prospective permutation scan modeling was performed using SatScan software. Results: A total of 5 359 CL and 23 malaria cases were predicted in 2016 using time-series models. Applied timeseries models were well-fitted regarding auto correlation function, partial auto correlation function sample/model, and residual analysis criteria(Pv was set to 0.1). The results indicated two significant prospective spatial-temporal outbreaks for CL(P<0.5) including Most Likely Clusters, and one non-significant outbreak for malaria(P>0.5) in the area. Conclusions: Both CL and malaria follow a space-time trend in the area, but prospective permutation scan modeling works better for detecting CL spatial-temporal outbreaks. It is not far away from expectation since clusters are defined as accumulation of cases in specified times and places. Although this method seems to work better with finding the outbreaks of a high-frequency disease; i.e., CL, it is able to find non-significant outbreaks. This is clinically important for both high-and low-frequency infections; i.e., CL and malaria.展开更多

Methods: A total of 451 pediatric patients with severe HFMD were randomly assigned to receive WM therapy alone(224 cases, WM therapy group) or CM [Reduning Injection(热毒宁注射液) or Xiyanping Injection(喜炎平注射液)] plus WM therapy(227 cases, CM plus WM therapy group) for 7–10 days, according to a web-based randomization system. The primary outcome was fever clearance time, which was presented as temperature decreased half-life time. The secondary outcomes included the rate of rash/herpes disappearance within 120 h, as well as the rate for cough, runny nose, lethargy and weakness, agitation or irritability, and vomiting clearance within 120 h. The drug-related adverse events were also recorded. Results: The temperature decreased half-life time was 40.4 h in the WM therapy group, significantly longer than 27.2 h in the CM plus WM therapy group(P<0.01). Moreover, the rate for rash/herpes disappearance within 120 h was 43.6%(99/227) in the CM plus WM therapy group, significantly higher than 29.5%(66/224) in the WM therapy group(P<0.01). In addition, the rate for cough, lethargy and weakness, agitation or irritability disappearance within 120 h was 32.6%(74/227) in the CM plus WM therapy group, significantly higher than 19.2%(43/224) in the WM therapy group(P<0.01). No drug-related adverse events were observed during the course of the study. Conclusions: The combined CM and WM therapy achieved a better therapeutic efficacy in treating severe HFMD than the WM therapy alone. Reduning or Xiyanping Injections may become an important complementary therapy to WM for relieving the symptoms of severe HFMD.展开更多

文摘Objective:To assess prevalence and intensity of soil-transmitted helminths(STH) in school age children of two southern districts as baseline information prior to implement a deworming program against intestinal parasites as part of an integrated country development plan.Methods:Children randomly selected from urban and rural schools in Southern Belize provided one stool sample each,analysed by the Kato-Katz method to assess prevalence and intensity of STH infections.Epi Info software was used for data analysis;Chi-square test and Fischer exact test were applied to compare group proportions;P<0.05 was considered of statistical significance;descriptive statistics were expressed as percentages.Results:A total of 500 children from 10 schools participated in the study from May to December2005.Prevalence of STH ranged between 40%and 82%among schools,with a median of 59.2%;the majority of light intensity,and with 2.2%high intensity infection.Trichuris and Axaris infections presented similar frequency in children aged from 6 to 9 years old;hookworm infections tended to be more frequent in the older group 10 to 12 years old.Statistical significances(P≤0.01)were found in children in rural schools infected with any species of STH,in moderate Trichuris infections,in hookworm infections in rural areas with strong Mayan presence and in Ascaris infections in children of Mayan origin.Conclusions:High prevalence of STH in Southern Belize provided sound ground for implementing an integrated deworming control program.
文摘Objective: To determine the endemic values of cutaneous leishmaniasis in different cities of Fars province, Iran. Methods: Totally, 29 201 cases registered from 2010 to 2015 in Iranian Fars province were selected, and the endemic values of cutaneous leishmaniasis were determined by retrospective clusters derived from spatiotemporal permutation modeling on a time-series design. The accuracy of the values was assessed using receiver operating characteristic(ROC) curve. SPSS version 22, Arc GIS, and ITSM 2002 software tools were used for analysis. Results: Nine statistically significant retrospective clusters(P<0.05) resulted in finding seven significant and accurate endemic values(P<0.1). These valid endemic scores were generalized to the other 18 cities based on 6 different climates in the province. Conclusions: Retrospectively detected clusters with the help of ROC curve analysis could help determine cutaneous leishmaniasis endemic values which are essential for future prediction and prevention policies in the area.

文摘Objective:To identify Leishman{u using PCR.Methods:This studs was conducted from April2009 to March 2011 in order to identify Leishmania species in a new endemic area of CL in Lorestan.Iran.Samples were taken from 62 patients that referred to the health centers in different cities of Lorestan province,the presence of Leishmcania was confirmed using direct smear and then grown in NNN media and mass cultured in RPM!1640 medium supplemented with 10%heat-inactivated fetal bovine serum.DNA was extracted from cultured promastigotes and used in P15-PCR.Results:45(72.6%)samples out of 62 showed a hand in the range of 485 hp and 17(27.4%)with a hand in the range of 626 hp which were similar to standard strains of Leichmania tropica(L.tropical and Leishnrania major(L.major),respectively.50(65.80%)of samples were collected from people with no history of travel in at least a year prior to the onset which shows that indigenous source of infection.Conclusions:Since the vector and reservoir of the two species are different.so precise and extensive control and prevention methods should be designed and earned out.
文摘OBJECTIVE To determine the association between viral loadof human papillomavirus 16 (HPV16) DNA in the primary focusof cervical carcinoma and HPV16 DNA in pelvic lymph nodes.METHODS The HPV16 DNA load was measured by fluorescentquantitation polymerase chain reaction (FQ-PCR) in 17 primaryfoci. HPV16 DNA was detected by polymerase chain reaction(PCR) using HPV16 type-specific primers in 296 pelvic lymphnodes which were from 17 cases of cervical cancer.RESULTS The viral load of HPV16 DNA showed statisticallysignificant differences between tumors with a diameter of < 4cm and ≥ 4 cm (P < 0.05). Seven of 17 cervical cancer cases hadHPV16 DNA positive lymph nodes, designated as the positivegroup, while the remaining 10 without positive lymph nodes wasdesignated the negative group. The average load of HPV16 DNAshowed no significant difference between the 2 groups (P > 0.05).The load of HPV16 in the primary lesion was not associated withthat in the lymph nodes. There were 38 HPV16 DNA positivenodes in the total 296 nodes. The rate of positivity of HPV16 DNAin lymph nodes showed statistically significant differences inconsideration of maximum tumor diameter, tumor differentiation,histologic type, depth of myometial infiltration and the metastaticstatus of the nodes, respectively (P < 0.05).CONCLUSION Viral load of HPV16 in the primary cancer focuscorrelated with the quantity of tumor cells in the primary focusbut not with the existence of HPV DNA positive lymph nodes.Detection of HPV DNA may help to find the early metastases thatcannot be evaluated histopathologically, but the prognostic valueof HPV positive lymph nodes needs further examination.
文摘Objective: To achieve optimal effect with beta-lactam antibiotics, regimens with frequent dosages have been found necessary. However, if compliance is negatively influenced by more frequent dosages, this might hamper the effect of the treatments. Therefore, we have studied whether the numbers of daily dosages influence the compliance with prescribed flucloxacillin regimens. Design: A prospective interview study of patients with different dosing regimens of flucloxacillin. Setting: In the study, 200 patients with different dosing regimens of flucloxacillin underwent structured telephone interviews in order to reveal their compliance with the medication. Of these, 13 were prescribed twice-daily doses, 163 three times daily and 24 patients four times daily regimens. Results: There were no statistically significant differences between missed doses and prescribed numbers of daily doses. There was, however, a significant difference in the number of daily doses and experiences associated with the medication. Conclusions: This study shows that patients comply well with regimens of up to four daily doses of flucloxacillin, despite experiencing increasing difficulties with regimens of more frequent dosages.

文摘Objective To evaluate the efifcacy and safety of traditional Chinese medicine (TCM) combined with Western medicine in the treatment of patients with common hand, foot and mouth disease (HFMD) by conducting a prospective, controlled, and randomized trial. Methods A total of 452 patients with common HFMD were randomly assigned to receive Western medicine alone (n=220) or combined with TCM (Reduning or Xiyanping injections) (n=232). The primary outcome was the incidence rate of rash/herpes disappearance within 5 days, while secondary outcomes included the incidence rate for fever, cough, lethargy, agitation, and vomiting clearance within 5 days. Results The rash/herpes disappearance rate was 45.5% (100/220) in Western medicine therapy group, and 67.2% (156/232) in TCM and Western medicine combined therapy group, with significant difference (P<0.001). Moreover, TCM remarkably increased the incidence rate of secondary disappearance, which was 56.4%in Western medicine therapy group and 71.4%in TCM and Western medicine combined therapy group (P=0.001). No drug-related adverse events were observed. Conclusions It’s suggested that the integrative TCM and Western medicine therapy achieved a better therapeutic efficacy. TCM may become an important complementary therapy on relieving the symptoms of HFMD.
文摘Objective: To determine whether permutation scan statistics was more efficient in finding prospective spatial-temporal outbreaks for cutaneous leishmaniasis(CL) or for malaria in Fars province, Iran in 2016. Methods: Using time-series data including 29 177 CL cases recorded during 2010-2015 and 357 malaria cases recorded during 2010-2015, CL and malaria cases were predicted in 2016. Predicted cases were used to verify if they followed uniform distribution over time and space using space-time analysis. To testify the uniformity of distributions, permutation scan statistics was applied prospectively to detect statistically significant and non-significant outbreaks. Finally, the findings were compared to determine whether permutation scan statistics worked better for CL or for malaria in the area. Prospective permutation scan modeling was performed using SatScan software. Results: A total of 5 359 CL and 23 malaria cases were predicted in 2016 using time-series models. Applied timeseries models were well-fitted regarding auto correlation function, partial auto correlation function sample/model, and residual analysis criteria(Pv was set to 0.1). The results indicated two significant prospective spatial-temporal outbreaks for CL(P<0.5) including Most Likely Clusters, and one non-significant outbreak for malaria(P>0.5) in the area. Conclusions: Both CL and malaria follow a space-time trend in the area, but prospective permutation scan modeling works better for detecting CL spatial-temporal outbreaks. It is not far away from expectation since clusters are defined as accumulation of cases in specified times and places. Although this method seems to work better with finding the outbreaks of a high-frequency disease; i.e., CL, it is able to find non-significant outbreaks. This is clinically important for both high-and low-frequency infections; i.e., CL and malaria.
文摘BACKGROUND Despite the Middle East and North Africa(MENA)Region reported to have the highest prevalence of hepatitis C virus(HCV)globally,HCV infection levels in the majority of MENA countries remain inadequately characterized.Blood donor data have been previously used as a proxy to assess levels and trends of HCV in the general population,however,it is unclear how comparable these populations are in MENA and whether blood donors provide an appropriate proxy.AIM To delineate HCV epidemiology among blood donors and the general population in the MENA.METHODS The data source was the systematically gathered MENA HCV Epidemiology Synthesis Project Database.Random-effects meta-analyses and meta-regressions were conducted.For comparison,analyses were conducted for Europe,utilizing the Hepatitis C Prevalence Database of the European Centre for Disease Prevention and Control.RESULTS One thousand two hundred and thirteen HCV antibody prevalence measures and 84 viremic rate measures were analyzed for MENA.Three hundred and seventyseven antibody prevalence measures were analyzed for Europe.In MENA,pooled mean prevalence was 1.58%[95%confidence interval(CI):1.48%–1.69%]among blood donors and 4.49%(95%CI:4.10%–4.90%)in the general population.In Europe,pooled prevalence was 0.11%(95%CI:0.10%–0.13%)among blood donors and 1.59%(95%CI:1.25%–1.97%)in the general population.Prevalence in the general population was 1.72-fold(95%CI:1.50–1.97)higher than that in blood donors in MENA,but it was 15.10-fold(95%CI:11.48–19.86)higher in Europe.Prevalence was declining at a rate of 4%per year in both MENA and Europe[adjusted risk ratio:0.96(95%CI:0.95–0.97)in MENA and 0.96(95%CI:0.92–0.99)in Europe].Pooled mean viremic rate in MENA was 76.29%(95%CI:67.64%–84.02%)among blood donors and 65.73%(95%CI:61.03%–70.29%)in the general population.CONCLUSION Blood donor data provide a useful proxy for HCV infection in the wider population in MENA,but not Europe,and could improve HCV burden estimations and assess progress toward HCV elimination by 2030.

文摘Objective: To evaluate the efficacy and safety of Chinese medicine(CM) plus Western medicine(WM) in the treatment of pediatric patients with severe hand, foot and mouth disease(HFMD) by conducting a prospective, controlled, and randomized trial. Methods: A total of 451 pediatric patients with severe HFMD were randomly assigned to receive WM therapy alone(224 cases, WM therapy group) or CM [Reduning Injection(热毒宁注射液) or Xiyanping Injection(喜炎平注射液)] plus WM therapy(227 cases, CM plus WM therapy group) for 7–10 days, according to a web-based randomization system. The primary outcome was fever clearance time, which was presented as temperature decreased half-life time. The secondary outcomes included the rate of rash/herpes disappearance within 120 h, as well as the rate for cough, runny nose, lethargy and weakness, agitation or irritability, and vomiting clearance within 120 h. The drug-related adverse events were also recorded. Results: The temperature decreased half-life time was 40.4 h in the WM therapy group, significantly longer than 27.2 h in the CM plus WM therapy group(P<0.01). Moreover, the rate for rash/herpes disappearance within 120 h was 43.6%(99/227) in the CM plus WM therapy group, significantly higher than 29.5%(66/224) in the WM therapy group(P<0.01). In addition, the rate for cough, lethargy and weakness, agitation or irritability disappearance within 120 h was 32.6%(74/227) in the CM plus WM therapy group, significantly higher than 19.2%(43/224) in the WM therapy group(P<0.01). No drug-related adverse events were observed during the course of the study. Conclusions: The combined CM and WM therapy achieved a better therapeutic efficacy in treating severe HFMD than the WM therapy alone. Reduning or Xiyanping Injections may become an important complementary therapy to WM for relieving the symptoms of severe HFMD.
