[Purpose] The aim of this study was to compare age-related differences in balance and
anthropometric posture measurements of the foot and to determine any relationship between
them. [Subjects and Methods] Sixty-eight older and 42 younger adults participated in this
study. Foot posture was tested for four domains: 1) hallux flexion and extension range of
motion using a goniometer, 2) navicular height and 3) length of the foot using a
pachymeter, and 4) footprint (width of forefoot, arch index and hallux valgus). Balance
was tested under two conditions on a force platform: bipodal in 60-s trials and unipodal
in 30-s trials. The sway area of the center of pressure and velocity in the
anteroposterior and mediolateral directions were computed. [Results] Older individuals
showed significantly poorer balance compared with younger adults under in the unipodal
condition (center of pressure area 9.97 vs. 7.72 cm2). Older people presented a
significantly lower hallux mobility and higher values for width of the forefoot and
transverse arch index than younger adults. The correlations between all foot posture and
center of pressure parameters varied across groups, from weak to moderate
(r −0.01 to −0.46). Low hallux mobility was significantly related to
higher center of pressure values in older people. [Conclusion] These results have clinical
implications for balance and foot posture assessments.Key words: Posture, Aging, Foot 相似文献

The present study further evaluated contextual factors (i.e., neighborhood violence and peer rejection) that contribute to academic performance by examining school attachment as a moderator of these associations in a sample of Latino high school students (N = 144, 54% male). Findings suggested that both neighborhood violence and peer rejection were negatively associated with academic performance. However, the influence of neighborhood violence depended on levels of school attachment, with neighborhood violence unrelated to poor academic performance when levels of school attachment were high. In contrast, peer rejection was robustly associated with poor academic performance, regardless of the level of school attachment. Implications of findings are discussed. 相似文献

Little is known about factors that account for the link between community violence exposure (CVE) and delinquency among adolescents. Sleep is one factor that warrants attention, given the poor sleep habits found among many adolescents and its relation to CVE and delinquent behaviors. Further, given the growing rate of Latino youth in the United States, and their risk for CVE, examining factors that account for this relation among Latino youth is essential for developing culturally sensitive interventions. This study evaluated whether sleep problems accounted for the link between CVE and delinquency among a sample of 144 Latino adolescents (54% male; ages 14–19 years). CVE and sleep problems were uniquely related to delinquency. Further, Meeker's test of indirect effects indicated that sleep problems partially accounted for the relation between CVE and delinquency. Interventions targeting sleep problems in Latino adolescents may aid in reducing delinquency among Latino adolescents, particularly for those with CVE. 相似文献

Visceral leishmaniasis (VL) is a neglected disease and is fatal if untreated. Dogs serve as reservoirs for Leishmania infantum (syn. L. chagasi) due to their susceptibility to infection and high skin parasitism. Therefore, VL control in Brazil involves the elimination of seropositive dogs, among other actions. However, the most frequently used serological tests have limitations regarding sensitivity and specificity. In this study, we have selected three Leishmania antigens (C1, C8 and C9) and have produced them as recombinant proteins using pET-28a-TEV vector and Escherichia coli BL-21 as expression system. When tested in ELISA with human samples, the C9 antigen was the one showing the most promising results, with 68% sensitivity and 78% specificity. When testing canine samples, the C1, C8 and C9 antigens showed a sensitivity range from 70% to 80% and specificity range from 60% to 90%. The C1 antigen presented higher sensitivity (80%) and the C8 antigen presented higher specificity (90%). Due to it, we decided to mix and test C1 and C8 antigens together, resulting in the C18 antigen. The mix also yielded high percentages of detected symptomatic and asymptomatic dogs however it did not improve the performance of the diagnostic. Comparison of our tests with the tests recommended by the Brazilian Ministry of Health revealed that our antigens’ sensitivities and the percentage of detected asymptomatic dogs were much higher. Our results suggest that the C1, C8, C18 and C9 recombinant proteins are good antigens to diagnose canine visceral leishmaniasis and could potentially be used in screening tests. To diagnose human visceral leishmaniasis, the C9 antigen presented reasonable results, but more optimization must be performed for this antigen to provide better performance. 相似文献

The objective of this study is to report on the colonization of palm trees
by Rhodnius neglectus, its invasion in an urban area, in Araçatuba -
São Paulo, and the control and surveillance measures that have been put in place.
Domiciliary triatomine searches occurred in apartments upon the inhabitants''
notification. The collected insects were identified and examined for natural
infection and food sources with a precipitin test. To search the palm trees, tarps
were used to cover the floor, and a “Munck” truck equipped with a tree-pruning device
was utilized. Chemical control was performed with the utilization of a manual
compression. In 2009, 81 specimens of Rhodnius neglectus were
collected from the domiciles by the population. The precipitin test revealed a
presence of human blood in 2.7% of the samples. Entomological studies were carried
out in these domiciles and in those located within a radius of 200 meters. The search
performed in the palm trees resulted in the capture of 882 specimens of triatomines,
negative for tripanosomatids. Mechanical and chemical controls were carried out. New
searches conducted in the palm trees in the same year resulted in the capture of six
specimens. The mechanical and chemical controls of the palm trees, together with the
population''s work, proved to be effective, therefore preventing these insects''
colonization of the city''s domiciles. 相似文献

Background
Metabolic syndrome (MS) is an aggregation of risk factors that increase the incidence of cardiovascular events and diabetes mellitus (DM). Population aging is accompanied by higher prevalence of MS, which varies depending on the population studied and the diagnostic criteria used.Objective
To determine prevalence of MS in the elderly using four diagnostic criteria and agreement between them.Methods
Cross-sectional study on 243 patients older than 60 years (180 women) in Niterói, RJ. They were evaluated by clinical examination, fasting glucose, fasting insulin, lipid profile and anthropometric measurements - weight, height, waist circumference and waist/hip ratio. Prevalence of MS was estimated by World Health Organization (WHO) modified, National Cholesterol Education Program - Adult Treatment Panel III (NCEP-ATP III), International Diabetes Federation (IDF) and Joint Interim Statement (JIS) criteria.Results
Prevalence was high with the four criteria WHO (51.9%), NCEP-ATPIII (45.2%), IDF (64.1%) and JIS (69.1%), and agreement between criteria by kappa was moderate in almost all comparisons WHO vs. IDF (k = 0.47;95% confidence interval (CI), 0.35 to 0.58); WHO vs. NCEP-ATPIII (k = 0.51; 95% CI, 0.40 to 0.61); WHO vs. JIS (k = 0.45; 95% CI, 0.33 to 0.56); IDF vs. NCEP-ATPIII (k = 0.55; 95% CI, 0.45 to 0.65) and NCEP-ATPIII vs. JIS (k = 0.53; 95% CI, 0.43-0.64), except between IDF vs. JIS (K = 0.89;95% CI, 0.83 to 0.95), which was considered good.Conclusion
Prevalence of MS was high with the four diagnostic criteria, mainly by JIS. There was good agreement between JIS and IDF criteria and moderate among the others. 相似文献38.
Background
The utility of screening for venous thromboembolism (VTE) in cancer patients is unknown. We evaluated this in a prospective cohort study of cancer patients initiating a new chemotherapy regimen and deemed high-risk (score ≥ 3) based on a validated Risk Score.Methods
Patients were evaluated with baseline and Q4 (± 1) week serial ultrasonography for up to 16 weeks; additionally, computed tomography scans for restaging were also evaluated for VTE.Results
The study population comprised 35 patients. Pancreatic and gastro-esophageal cancers were the most common diagnoses. Of these, 8 (23%) developed a VTE. This included 5 patients with DVT alone (14%), 1 patient with PE alone (3%) and 2 (6%) with both. Ultrasound examinations identified asymptomatic DVT in 9.3% of patients at baseline; 0% at weeks 4 and 8 and 5.6% at week 12. Restaging CT scans identified asymptomatic PE in one patient at week 6 and in one patient at week 9 with subsequent DVT at week 10.Conclusions
Screening for asymptomatic VTE has not been previously used as a clinical strategy in ambulatory cancer patients. We report that one-tenth of patients at baseline had occult DVT and in this high-risk population, screening at baseline may be of value. 相似文献39.
