From January 2001 to October 2002 captures were made in domicile and peridomiciliary areas of 13 cities of region of Cariri, south of the State of Ceará. As results, the occurrence of P. lutzi in this area was noticed, for the first time, in three cities: the presence of one adult in chicken house in Altaneira, one adult flying, in Salitre and 18 nymphs in Varzea Alegre(13 in bricks pile and five in roofing tile pile). In Varzea Alegre city it was observed the colonization in the peridomicile.  相似文献

Analysis of 27 rotavirus strains from vaccinated and unvaccinated children revealed reassortment events in 3 strains: a gene derived from a vaccine; a gene acquired from a circulating strain; and reassortment between circulating strains. Data suggest that the widespread use of this monovalent rotavirus vaccine may introduce vaccine genes into circulating human rotaviruses or vice versa.  相似文献

OBJECTIVES: To establish the prevalence and distribution of witnesses, victims, and perpetrators of different types of violence in the general population and the proportion of victims consulting health services or reporting the incident to authorities. METHODS: Cross sectional survey of a random sample of 3007 inhabitants between the ages of 15 and 60 in the city of Bogotá, Colombia, in 1997, based on a face to face interview. RESULTS: Age adjusted past year prevalence of witnesses, victims, and perpetrators of physical aggression was 61%, 27%, and 27%, respectively, while lifetime prevalence of witnesses, victims, and perpetrators of assault with a weapon in this population reached 70%, 55%, and 5.8%. Between 11% and 67% of the victims consulted a health service and less than 32% reported the incident to an authority. Those involved in most types of physical violence tended to be young, male, from lower middle social classes, with some degree of secondary education, and single or divorced. CONCLUSIONS: Prevalence of witnesses and victims of violence in this sample appears to be high, while perpetrators constitute a small proportion. Violence is not equally distributed throughout the population suggesting the possibility of identifying a population at higher risk for the development of intervention programmes.  相似文献

AIDS is a major public health problem reaching all social strata. Knowing about the ways of transmission is a way of preventing the disease. For evaluating the level of knowledge of the population of the city of Vi?osa about AIDS transmission, a questionnaire about the ways of transmission of the disease based on studies made in Europe was applied to 376 individuals. The questionnaire consisted of eleven multiple-choice questions about the ways of AIDS transmission, sex, age and educational level of the interviewees. The results showed that the ways of transmission emphasized in health campaigns are well assimilated, while the questions about everyday situations that offer no risk received a high number of incorrect answers. The differences were not significant when data were stratified by sex. The same data stratified by age or educational level showed significant differences for some questions; people aged over 55 and with a lower educational level had a significantly higher number of incorrect answers. It can be concluded that the population of Vi?osa knows the main ways of AIDS transmission, but a part of the population does not know that some everyday situations do not pose risk of transmission. These data can be useful for the preparation of elucidative campaigns for reducing prejudice.  相似文献

Epidemiological and entomological surveys were carried out in the human and mosquito populations in Maceió, Alagoas, in order to assess the present status of bancroftian lymphatic filariasis. Examination of thick blood smears of 10,450 students from different areas of the city revealed 0.66% Wuchereria bancrofti microfilaria carriers. The distribution of filariasis is focal in the city, 80% of the individuals with patent infection living in two neighboring areas with 1.24% and 5.25% prevalence. Parallel studies performed with samples of all age groups in the human population showed similar microfilaria prevalence rates observed previously in the student survey. However, thick blood smears taken from members of families with at least one subject with patent infection gave a prevalence six times greater suggesting, increased transmission in households. The percentage of carriers was higher in the youngest age group (< 20 years). Culex quinquefasciatus mosquitos caught at the locations where the autochthonous cases were found presented natural infection rates ranging from 0.28% to 4.62%. The combination of all these findings indicates occurrence of active transmission of W. bancrofti in the urban area of Maceió, Alagoas State. Based on these data, measures for the potential control of filariasis were planned.  相似文献

Heavy metal concentrations were monitored in agricultural soils and irrigation groundwaters of Koropi–Markopoulo area, a representative agricultural suburb in Athens, Greece, aiming at the identification of the sources of contaminants. Multivariate analyses of geochemical data demonstrated that agricultural practices and industrial activities considerably affected the quality of both environmental compartments. The levels of Ni, Cr, Co, Mn and Fe in agricultural soils were associated with geological parent materials whereas Pb, Zn and Cu mainly originated from anthropic activities. Referring to groundwaters, individual major anions and cations (K+, Na+, Ca2+, Mg2+, NO3 ?, SO4 2?, Cl?) were influenced by various natural and anthropogenic factors whereas Ni, Cr, Cu and Zn were controlled by industrial and agronomic activities. The identification of the sources of contaminants in soil and groundwater environments is a valuable basis for encouraging mitigation strategies preventing further quality degradation.  相似文献

The aim of this study was to estimate the prevalence, awareness, treatment, and control of systemic arterial hypertension in the adult urban population of Tubar?o, Santa Catarina, Brazil. The cross-sectional approach used a stratified sample, based on an initial list of electric power connections, resulting in the selection of 707 individuals over 18 years of age. A questionnaire was applied and arterial blood pressure was measured twice by medical students during home visits, using a mercury sphygmomanometer. The prevalence of arterial hypertension based on the Seventh Report of the Joint National Committee on the Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (arterial pressure > 140 x 90 mmHg) was 36.4%, increasing to 40.5% when including individuals on anti-hypertensive medication. Of the patients with high blood pressure, 55.6% were aware of their hypertension, 46.8% were on medication, and 10.1% had their blood pressure under control. The high estimated prevalence of hypertension, low level of unawareness, and less than ideal treatment and control levels emphasize the need for preventive measures in Tubar?o.  相似文献

Cuprimine? and Syprine? are therapeutics approved by the USFDA to treat copper overload in Wilson Disease (a genetic defect in copper transport) by chelation and accelerated excretion of internally-deposited copper. These oral therapeutics are based on the respective active ingredients D-penicillamine (DPA) and N,N'-bis (2-aminoethyl) -1,2-ethanediamine dihydrochloride (Trien). Cuprimine is considered the primary treatment, although physicians are increasingly turning to Syprine as a first-line therapy. Both drugs exhibit oral systemic activity and low toxicity; their biological effects and safety are established. Previous in vivo studies using a rodent animal model established the decorporation potential of Cuprimine and Syprine for (60)Co and (210)Po. Currently these studies are being expanded to evaluate the in vivo decorporation efficacy of these drugs for several additional radionuclides. In this report, results of this investigation are discussed using the radionuclides (137)Cs, (60)Co, (192)Ir and (85)Sr. Short-term 48-h pilot studies were undertaken to evaluate DPA and Trien for their in vivo decorporation potential using male Wistar-Han rats. In these studies, a radionuclide solution was administered to the animals by intravenous (IV) injection, followed by a single IV dose of either DPA or Trien. Control animals received the radionuclide alone. Results show effective decorporation of (60)Co by DPA within the time frame evaluated. DPA and Trien were also modestly effective in decorporation of (137)Cs and (85)Sr, respectively. The study did not find DPA or Trien effective for decorporation of (192)Ir. Based on these encouraging findings, further studies to evaluate the dose-response profiles and timing of the chelator administration post exposure to radionuclides are warranted.  相似文献

OBJECTIVE: To evaluate the association between gingival health conditions and dental service utilization. METHODS: An epidemiological survey of the oral health of 1,799 adolescents was carried out in 35 cities of the state of S?o Paulo, in 2002. Gingival health was assessed through the prevalence of gingival bleeding on probing and dental calculus (community periodontal index), and dental occlusion was assessed through the dental aesthetic index. The utilization of dental services was measured by means of the dental care index (F/DMFT) for each city. Multilevel logistic regression analysis was used to adjust explanatory models to factors associated with the outcome variables of interest. RESULTS: The prevalence of gingival bleeding on probing was 21.5%, whereas dental calculus was prevalent in 19.4%. Male participants, who were either black or dark-skinned, lived in crowded homes, in rural areas, and showed schooling delay, were at a significantly higher risk than their respective counterparts. The following dental occlusion characteristics were also associated with unhealthy gum: incisor segment crowding, vertical anterior open bite, and antero-posterior molar relationship. Cities with a higher utilization of dental services showed a smaller proportion of adolescents with gingival bleeding and dental calculus. CONCLUSIONS: The utilization of dental services was significantly associated with better gingival health conditions (gingival bleeding and dental calculus). This association did not depend on contextual and individual sociodemographic characteristics or dental occlusion.  相似文献

A series of 9-N-substituted berberine derivatives were synthesized and biologically evaluated as antioxidant and inhibitors of acetylcholinesterase (AChE), butyrylcholinesterase and amyloid-β aggregation. Most of these compounds exhibited very good antioxidant activities, inhibitive activities of AChE and amyloid-β aggregation. Among them, compound 8d, (o-methylphenethyl)amino linked at the 9-position of berberine, was found to be a good antioxidant (with 4.05 μM of Trolox equivalents), potent inhibitor of AChE (an IC50 value of 0.027 μM), and high active inhibitor of amyloid-β aggregation (an IC50 value of 2.73 μM).  相似文献

The objective of this study was to analyze the characteristics and place of occurrence of injuries treated in emergency departments. A total of 35,107 emergency department visits for injuries were analyzed, excluding traffic injuries, in S?o Paulo State, Brazil, 2005. The majority of victims were male (59.1%), and from 0 to 29 years of age (62.1%). Leading causes were falls (39.3%) and accidental blows (16.5%). Most injuries occurred in the home (64.7%), followed by public places (19.9%). Assaults were more frequent in public. Women were more likely to suffer injuries at home, as compared to men (OR = 0.51; 95% CI: 0.48-0.53). Men were 1.34 times more likely to be injured in public places, 3.22 times in bars, and 2.82 times in the workplace. A higher proportion of events among children aged 0 to 9 and individuals 60 years or older occurred at home. The results highlighted the home as an important place for the occurrence of injuries, which should be considered when planning injury prevention programs.  相似文献

In 2007, a surveillance system for influenza-like illness (ILI) and virologic data was established in Beijing, China. The system tracked ILI and laboratory-confirmed influenza in 153 general hospitals from September 1, 2007, through April 30, 2008. To analyze the ILI surveillance data (weekly ILI rates and counts) and the effectiveness of the system, we used the US Centers for Disease Control and Prevention Early Aberration Reporting System. The data indicated that the highest rate of influenza isolation and the highest ILI count occurred in the first week of 2008. The system enabled us to detect the onset and peak of an epidemic.  相似文献

In 2004, routine use of culture and drug-susceptibility testing (DST) was implemented for persons in 5 Thailand provinces with a diagnosis of tuberculosis (TB). To determine if DST results were being used to guide treatment, we conducted a retrospective chart review for patients with rifampin-resistant or multidrug-resistant (MDR) TB during 2004–2008. A total of 208 patients were identified. Median time from clinical sample collection to physician review of DST results was 114 days. Only 5.8% of patients with MDR TB were empirically prescribed an appropriate regimen; an additional 31.3% received an appropriate regimen after DST results were reviewed. Most patients with rifampin -resistant or MDR TB had successful treatment outcomes. Patients with HIV co-infection and patients who were unmarried or had received category II treatment before DST results were reviewed had less successful outcomes. Overall, review of available DST results was delayed, and results were rarely used to improve treatment.  相似文献

The prevalence of obesity in Araraquara, a county of 150,000 inhabitants situated 250 km from S. Paulo, Brazil was studied. The study population, of 18-74 yrs. of age, resident in the urban area in 1987, was composed of 1,126 inhabitants, 502 males and 624 females, selected through a cluster equiprobabilistic sampling process. The prevalence of overweight (Quetelet 25-29.9 Kg/m2) was 26.9% for males and 27.7% for females. The prevalence of obesity (Quetelet equal or greater than 30.0 kg/m2) was 10.2% for males and 14.7% for females. These percentages are high when compared with those of affluent Anglo-saxon countries. The reasons for this phenomenon are discussed in the light of the fact that the economy of the city is affluent and is dependent on agroindustrial activities. When own cut-off criteria (P85 and P95 for Quetelet for 20-29 yrs of age, for each sex) are calculated, the "lean pattern" for Araraquara County is leaner than that for the a United States population. This raises doubts as to the possibility of applying cut-off criteria of particular regions to regions of different characteristics.  相似文献
