BackgroundSoil-transmitted helminth (STH) infections are still prevalent among schoolchildren in the Philippines. We evaluated the risk factors associated with STH and the relationship between STH and nutritional indices among schoolchildren aged 9–10 years in Laguna province, the Philippines.MethodsWe used the baseline data from 40 schools enrolled in a randomised controlled trial of the Magic Glasses Philippines health education package. Data on demographic and socio-economic variables, and STH related knowledge, attitudes and practices, were obtained through a questionnaire. Stool samples were collected and assessed for STH egg presence using the Kato-Katz technique. Haemoglobin levels and height and weight of study participants were also determined. The generalized estimating equations approach was used to construct logistic regression models to assess STH-associated risk factors, and the association between any STH infection and anaemia, child stunting, wasting and being underweight. The trial is registered with the Australian New Zealand Clinical Trials Registry (ACTRN12616000508471).FindingsAmong 1,689 schoolchildren, the prevalence of any STH was 23%. The prevalence of anaemia, stunting, being underweight and wasting was 13%, 20.2%, 19% and 9.5%, respectively. Age, socio-economic status, rural/urban classification of schools and knowledge of STH were significant risk factors for acquiring a STH infection. Moreover, infections with any STH were significantly associated with stunting (P = <0.001) and being underweight (P = <0.003), but not wasting (P = 0.375) or anaemia (P = 0.462) after controlling for confounding covariates.ConclusionThe study findings emphasise the need for sustainable deworming in tandem with other measures such as the provision of health education, improvements in sanitation and hygiene, and nutritional programs in order to control STH infections and improve morbidity outcomes in schoolchildren.Trial registrationAustralian New Zealand Clinical Trials Registry (ACTRN12616000508471). 相似文献

SYNOPSIS. Antisera were developed in rabbits against homogenized antigens prepared from 3 axenic lines of Trichomonas gallinae: JB(VI), the 6th isolate of the very virulent Jones' Barn strain which was kept frozen in liquid nitrogen and was fully pathogenic for pigeons at the time at which it was employed for immunization; JB (VI)C, a substrain derived from JB(VI), but attenuated during continuous in vitro cultivation for 1 year; and JB(V)C, a substrain of the 5th isolate of the Jones' Barn strain attenuated during continuous in vitro cultivation for over 3 years. Globulin fractions of the antisera were conjugated with fluorescein isothiocyanate (FITC), and fractionated on DEAE-cellulose columns to yield highly specific fractions. Intact, formalin-fixed flagellates of each line were stained on slides with each labelled antiserum under standardized conditions. Fluorescence emitted by individual organisms was measured with the aid of a special microfluorimetric apparatus. Experiments involving direct staining, one-step inhibition, and cross-absorption methods indicated the presence of unique and cross-reacting antigenic systems in each of the 3 lines of trichomonads. The 2 substrains attenuated in the course of prolonged in vitro cultivation, altho antigenically similar, could be readily differentiated from each other. Further, both of them appeared to contain more antigenic systems than the still fully virulent JB(VI) parasites. 相似文献

We have leveraged a Drosophila model relevant to Alzheimer disease (AD) for functional screening of findings from a genome-wide scan for loci associated with a quantitative measure of AD pathology in humans. In six of the 15 genomic regions evaluated, we successfully identified a causal gene for the association, on the basis of in vivo interactions with the neurotoxicity of Tau, which forms neurofibrillary tangles in AD. Among the top results, rs10845990 within SLC2A14, encoding a glucose transporter, showed evidence of replication for association with AD pathology, and gain and loss of function in glut1, the Drosophila ortholog, was associated with suppression and enhancement of Tau toxicity, respectively. Our strategy of coupling genome-wide association in humans with functional screening in a model organism is likely to be a powerful approach for gene discovery in AD and other complex genetic disorders. 相似文献

Traditional asylum care of psychiatric patients leads to the isolation, confinement, and restraint of the patients, and to isolation of psychiatric practice from the rest of medicine. Modern psychiatric advances have demonstrated the disadvantages to both patients and their families of such isolation, confinement and restraint. It is in the best interests of patients and professional workers that inpatient psychiatric services be continuous with, and contiguous to, other medical services and to rehabilitation services of all kinds.Examination of currently available information reveals a shortage of psychiatric beds in California, particularly for diagnosis and brief treatment. Thus, not only is there a need to develop psychiatric inpatient facilities, but also an opportunity to develop them along several different lines. Since both the Hill-Burton Act (federal) and the Short-Doyle Act (state) give financial assistance to only those psychiatric services established in general hospitals or affiliated with general hospitals, this requirement calls for examination in the light of experience with services so operated.At first, the Short-Doyle Act was perceived as a panacea for the psychiatric ills of the state. Now it is beginning to be recognized as one method of providing additional mental health resources, rather than the exclusive method. As more short-term cases are treated in local, tax-supported, psychiatric units in general hospitals, an impact can be expected on the state hospital program.In its administration of the Short-Doyle Act, the Department of Mental Hygiene attempts to respond to community needs as locally determined. It tries to insure local option and encourage local responsibility while furthering high standards of staffing and of service. 相似文献

Recent studies suggest the potential involvement of CD8+ T cells in the pathogenesis of murine hypertension. We recently reported that immunization with apoB-100 related peptide, p210, modified CD8+ T cell function in angiotensin II (AngII)-infused apoE (-/-) mice. In this study, we hypothesized that p210 vaccine modulates blood pressure in AngII-infused apoE (-/-) mice. Male apoE (-/-) mice were immunized with p210 vaccine and compared to unimmunized controls. At 10 weeks of age, mice were subcutaneously implanted with an osmotic pump which released AngII for 4 weeks. At 13 weeks of age, p210 immunized mice showed significantly lower blood pressure response to AngII compared to controls. CD8+ T cells from p210 immunized mice displayed a different phenotype compared to CD8+ T cells from unimmunized controls. Serum creatinine and urine albumin to creatinine ratio were significantly decreased in p210 immunized mice suggesting that p210 vaccine had renal protective effect. At euthanasia, inflammatory genes IL-6, TNF-α, and MCP-1 in renal tissue were down-regulated by p210 vaccine. Renal fibrosis and pro-fibrotic gene expression were also significantly reduced in p210 immunized mice. To assess the role of CD8+ T cells in these beneficial effects of p210 vaccine, CD8+ T cells were depleted by CD8 depleting antibody in p210 immunized mice. p210 immunized mice with CD8+ T cell depletion developed higher blood pressure compared to mice receiving isotype control. Depletion of CD8+ T cells also increased renal fibrotic gene expression compared to controls. We conclude that immunization with p210 vaccine attenuated AngII-induced hypertension and renal fibrosis. CD8+ T cells modulated by p210 vaccine could play an important role in the anti-hypertensive, anti-fibrotic and renal-protective effect of p210 vaccine. 相似文献
