OBJECTIVE: To quantify the dietary calcium and vitamin D intake in adult renal-transplant recipients attending at a large teaching hospital in Ireland for follow-up. SETTING: Outpatient renal-transplant follow-up clinic. SUBJECTS: Fifty-nine adult renal transplant recipients (58% male) with a mean age of 46 years, a median transplant duration of 6 years, and a mean estimated glomerular filtration rate (eGFR) of 50 mL/min per 1.73 m2. Fifty-three percent were at National Kidney Foundation stage 3 chronic kidney disease, and 14% had stage 4 chronic kidney disease. INTERVENTION: This cross-sectional, observational study used a tailored food frequency questionnaire specific for calcium and vitamin D intake in Irish adults, which was completed during a face-to-face interview with each subject. MAIN OUTCOME MEASURE: The main outcome measure was the average daily dietary and supplemented calcium and vitamin D intake. RESULTS: The median interquartile range (IQR) dietary calcium intake was 820 mg/day (range, 576-1,177 mg/day), and was similar in men and women (recommended intake > or = 1,000 mg/day in adult men and nonmenopausal adult women, > or = 1,500 mg/day in menopausal women). Five participants received calcium supplementation. Overall, 59% of men and 64% of women had total calcium intakes below the recommended amounts. The median IQR estimated dietary vitamin D intake was 5.2 microg/day (range, 2.4-6.4 microg/day) in women, and 4.6 microg/day (range, 2.2-6.6 microg/day) in men (recommended intake, > or = 10 microg/day). Six subjects received vitamin D supplementation. Total vitamin D intakes were suboptimal in 91% of men and 87% of women. Dietary calcium and vitamin D intakes significantly correlated with each other, but neither was significantly related to eGFR category, and was similarly low in both presumed menopausal women and in the initial year posttransplantation. CONCLUSION: These findings suggest that dietary and total calcium and vitamin D intakes in adult renal-transplant patients are in many cases inadequate. 相似文献

Objective Detection of HPV DNA in oral and genital lesions of a heterosexual male. 4 months after oral and vaginal intercourse with a woman with vulvar warts. Passible modes of acquisition of oral HPV infection in the male sexual partner are discussed. Setting Genitourinary Medicine clinic. Methods Polymerase chain reaction amplification of genomic DNA from oral and genital lesions. HPV DNA typing by dot blot hybridization. Results HPV DNA types 6 and 11 were identified in a polypoid tongue lesion and in a penile wart from the male sexual partner. Conclusions The acquisition of oral HPV infection in the male sexual partner may have resulted from genital-oral HPV transfer, either by direct contact with vulvar warts or by digital self-inoculation. 相似文献

Current HIV/AIDS statistics show that women account for almost 60% of HIV infections in Sub-Saharan Africa. HIV prevention
tools such as male and female condoms, abstinence and monogamy are not always feasible options for women due to various socio-economic
and cultural factors. Microbicides are products designed to be inserted in the vagina or rectum prior to sex to prevent HIV
acquisition. 相似文献

Small-cell lung cancer presenting with a combination of cranial diabetes insipidus and Cushing's syndrome secondary to ectopic
adrenocorticotropin (ACTH) secretion is very rare and has only been described previously in one case report Our patient was
a 49 year old man, in whom the initial presenting features of small-cell lung cancer were cranial diabetes insipidus secondary
to pituitary metastases and severe hypokalaemia resulting from ectopic ACTH hormone secretion. This case is a remarkable example
of the complex metabolic endocrine manifestations of small-cell lung cancer. 相似文献

The European Study Group on diastolic heart failure requires objective evidence of abnormal left ventricular diastolic function to establish the diagnosis of diastolic heart failure, which is common in older people. Reference values for Doppler indices of transmitral flow, used to assess left ventricular diastolic function, have not been reported for people 70 years and over in Europe. The aim of this study was to establish reference values for these Doppler indices of transmitral flow in older people. A random sample of 355 subjects aged 70 and over, living in the community underwent clinical assessment and echocardiography. Asymptomatic subjects with no cardiovascular disease and cardiovascular risk factors were identified. Measurements of five commonly used Doppler indices of transmitral flow from these subjects were obtained and reference range expressed as mean+/-2 standard deviations and as percentiles. We have therefore generated reference Doppler values of transmitral flow for people aged over 70 in a British population. 相似文献

While knowledge about the World Health Organisation’s (WHO) healthy schools model has been developed in recent years, process implementation and outcomes for school children have not improved in line with these advances. This deficit has become known as the ‘implementation gap’ and refers to the difference between the evidence of what works in theory and what is delivered in practice. The aim of this research was to evaluate the first implementation and impact of the WHO model among urban disadvantaged school children in Ireland from 2008 to 2012. A concurrent mixed methods study design was used. A process evaluation-mapped implementation and a three-year cohort study measured the impact. Data comprised of semi-structured interviews, focus groups and documentary analysis. Instruments included the Kidscreen-27 and the Child Depression Inventory (CDI). Over 600 children in five intervention and two comparison schools were recruited. The process evaluation revealed that top-down decision making based on the communities rather than each individual school’s needs and a lack of understanding of the concept of the whole school approach inhibited implementation. No significant differences were found between intervention and comparison of schools over three years post implementation. The successful implementation within an urban disadvantaged region requires not an analysis of the regional needs but a development of the individual school needs and sufficient lead-in time to ensure that each school is ready in terms of its understanding. Furthermore, healthy schools coordinators roles need to be clarified as facilitators of development and change rather than as unsustainable providers of health activities. 相似文献
