Two girls (a 5 year old and a 21 month old) experiencing mononucleosis syndrome with coincidental human herpesvirus (HHV)-7 and Epstein-Barr virus (EBV) infections are described. One patient had primary HHV-7 infection and reactivated EBV infection. The other had primary HHV-7 and EBV infections. These cases indicated that HHV-7 is capable of inducing infectious mononucleosis-like illness. Multiple herpesvirus infection in one of the patients also suggests that interaction among herpesviruses can occur in vivo. The consequence of this interaction may have clinical implications. 相似文献

OBJECTIVE: To determine the coverage and focus of cervical cancer screening (Pap smears) in a population-based sample in Brazil. METHODS: Cross-sectional cluster survey covering 1730 women aged 20 years or older with a history of sexual activity. Information was collected on social, demographic and behavioral variables, knowledge of and use of the Pap test. RESULTS: Of women aged 25-59 years, who are the target population of the national cervical cancer screening program, 78.7% had had at least one Pap test in their lifetime, and 68.8% had had a Pap test in the last 3 years. Statistics for focus of the program showed that of the 637 women who reported having a Pap test in the last year, only 20.6% actually required one. The remainder were either outside the age range or had had another test less than 30 months previously. Prevalence of not having been tested in the previous 3 years was highest among black (41.7%) and low-income women (64.3%), and among those at greatest risk for cervical cancer (62.3% for women with three or more risk factors). Focus was inversely related to socioeconomic status. CONCLUSION: Coverage rates were similar to those reported in other national studies, but this is the first report to examine the focus of the national program. We show that 8 of every 10 Pap tests were not necessary. Coverage levels remain unacceptably low among women of low socioeconomic status and those at greatest risk for cervical cancer. 相似文献

Improved contractility of obstructed bladders after Tadenan treatment is associated with reversal of altered myosin isoform expression 总被引:3,自引:0,他引:3
PURPOSE: Tadenan is a plant extract from Pygeum africanum used in the treatment of benign prostatic hyperplasia, to protect the bladder from contractile dysfunction induced by partial bladder outlet obstruction (BOO). The aim of the present study was to determine whether the Tadenan-induced return of detrusor contractility affects the expression of myosin isoforms, which differ at the C-terminal (SM1 and SM2) and the N-terminal regions (SM-A and SM-B). MATERIALS AND METHODS: Four groups of New Zealand White rabbits (3 to 5 kg., 4 to 6 rabbits per group) were either partially obstructed by ligation of the urethra (groups 1 and 2) or not obstructed (groups 3 and 4). After 2 weeks, rabbits from groups 2 and 4 received Tadenan in peanut oil (vehicle) orally at 100 mg. /kg./day for 3 weeks and rabbits in groups 1 and 3 received vehicle only. Rabbits were sacrificed and bladders were removed and weighed. Contractility studies were performed on isolated strips of detrusor and the remaining muscular layer from the bladder body was used to study the expression of myosin heavy chain (MHC) isoforms at mRNA (SM1, SM2, SM-A, and SM-B) and the protein (SM1 and SM2) levels by RT-PCR and SDS-PAGE analyses, respectively. RESULTS: Tadenan significantly reduced the effect of BOO on bladder mass. The diminished contractile response to field stimulation and carbachol secondary to urethral obstruction was significantly reversed by Tadenan treatment. The relative ratios for MHC isoforms were altered at the mRNA (SM2:SM1 and SM-A:SM-B) and protein (SM2:SM1) levels in obstruction. Upon treatment with Tadenan, the ratio of these isoforms returned to normal, as shown at the mRNA levels. In addition, the altered relative ratio of SM2:SM1 at the protein level also returned to nearly normal values after treatment. CONCLUSIONS: Improvement of obstruction-induced contractile dysfunction of the detrusor following treatment with Tadenan is associated with changes in the expression of myosin isoforms. The alteration in the expression of myosin isoforms associated with obstruction-induced hypertrophy is reversed close to normal in the detrusor smooth muscle from Tadenan-treated obstructed rabbits. 相似文献

OBJECTIVE: To describe strategies employed during handoffs in four settings with high consequences for failure. DESIGN: ANALYSIS: of observational data for evidence of use of 21 handoff strategies. SETTING: NASA Johnson Space Center in Texas, nuclear power generation plants in Canada, a railroad dispatch center in the United States, and an ambulance dispatch center in Toronto. MAIN MEASURE: Evidence of 21 handoff strategies from observations and interviews. RESULTS: Nineteen of 21 strategies were used in at least one domain, on at least an 'as needed' basis. CONCLUSIONS: An understanding of how handoffs are conducted in settings with high consequences for failure can jumpstart endeavors to modify handoffs to improve patient safety. 相似文献

Glycosmis arborea is a plant possessing various medicinal properties. The aim of the present study was to investigate the hepatoprotective efficacy of the butanol extract obtained from the aerial parts of the plant. The test sample was prepared by extracting the material through different steps. The extract thus obtained was dissolved in normal saline. Albino rats were prophylactically treated with the extract (i.p.) for 3 weeks. At the end of 3rd week all the groups were injected with hepatotoxic agents. After 48 h of injection, blood was collected and livers were taken out. Different enzymes in the serum were assayed and histopathological study was performed with liver. Glycosmis arborea extract was able to overcome the toxic effects of hepatotoxic agents in terms of lowering the levels of serum GPT, alkaline phosphatase and increased level of SOD in serum. TBARS generation in liver was also altered. Moreover, necrosis of liver produced by carbon tetrachloride was reversed by the extract. 相似文献

BackgroundUnderlying conditions are risk factors for severe COVID-19 outcomes but evidence is limited about how risks differ with age.AimWe sought to estimate age-specific associations between underlying conditions and hospitalisation, death and in-hospital death among COVID-19 cases.MethodsWe analysed case-based COVID-19 data submitted to The European Surveillance System between 2 June and 13 December 2020 by nine European countries. Eleven underlying conditions among cases with only one condition and the number of underlying conditions among multimorbid cases were used as exposures. Adjusted odds ratios (aOR) were estimated using 39 different age-adjusted and age-interaction multivariable logistic regression models, with marginal means from the latter used to estimate probabilities of severe outcome for each condition–age group combination.ResultsCancer, cardiac disorder, diabetes, immunodeficiency, kidney, liver and lung disease, neurological disorders and obesity were associated with elevated risk (aOR: 1.5–5.6) of hospitalisation and death, after controlling for age, sex, reporting period and country. As age increased, age-specific aOR were lower and predicted probabilities higher. However, for some conditions, predicted probabilities were at least as high in younger individuals with the condition as in older cases without it. In multimorbid patients, the aOR for severe disease increased with number of conditions for all outcomes and in all age groups.ConclusionWhile supporting age-based vaccine roll-out, our findings could inform a more nuanced, age- and condition-specific approach to vaccine prioritisation. This is relevant as countries consider vaccination of younger people, boosters and dosing intervals in response to vaccine escape variants. 相似文献

BackgroundFrailty negatively affects the outcomes of patients with cancer, and its assessment might vary widely in the real world. The objective of this study was to explore awareness and use of frailty screening tools among the ONCOassist healthcare professionals (HCPs) users.Materials and MethodsWe sent 2 emails with a cross-sectional 15-item survey in a 3-week interval between April and May 2021. Differences in the awareness and use of tools according to respondents’ continents, country income, and job types were investigated.ResultsSeven hundred thirty-seven HCPs from 91 countries (81% physicians, 13% nurses, and 5% other HCPs) completed the survey. Three hundred and eighty-five (52%) reported assessing all or the majority of their patients; 518 (70%) at baseline and before starting a new treatment. Three hundred and four (43%) HCPs were aware of performance status (PS) scores only, 309 (42%) age/frailty/comorbidity (AFC) screening, and 102 (14%) chemotoxicity predictive tools. Five hundred and thirty-seven (73%) reported using tools; 423 (57%) just PS, 237 (32%) AFC, and 60 (8%) chemotoxicity ones. Reasons for tools non-use (485 responders) were awareness (70%), time constraints (28%), and uselessness (2%). There were significant differences in awareness and use of screening tools among different continents, country income, job types, and medical specialties (P < .001 for all comparisons).ConclusionAmong selected oncology HCPs, there is still a worldwide lack of knowledge and usage of frailty screening tools, which may differ according to their geography, country income, and education. Targeted initiatives to raise awareness and education are needed to implement frailty assessment in managing patients with cancer. 相似文献
