Good foot health throughout childhood is important but remains poorly understood with few studies exploring this topic. The aim of this study was to define parents' knowledge, practices and health-related perceptions of children's feet. A qualitative design was adopted. Semi-structured, one-to-one interviews were carried out with parents of children aged five years and under, recruited from South East and North West of England. Interviews explored parents' views, beliefs and understanding of foot health in infancy and early childhood. Transcripts of the interviews were analysed using thematic analysis. Eighteen interviews were conducted. Seven themes were identified relating to (1) parents belief and knowledge about children's foot health; (2) how parents use and share foot health information; (3) activities for supporting foot health and development; (4) footwear choices, beliefs and influences; (5) the way they access health professionals; (6) the way they search for foot health information and (7) developing practice(s) to support parents. The study provides the first insight into how parents view foot health in early infancy and childhood. The findings highlight the key foot health beliefs important to parents, how they learn about and what influences their decision-making about caring for children's feet, the way parents receive and seek information, and how they access support for foot health concerns. The findings highlight the need for accurate, clear and consistent foot health messages, and the important role health professionals have in signposting parents towards reliable and informative sources on foot health.

The article focuses on a narrative literature review that identify the specific factors associated with systemic lupus erythematosus (SLE) that may have implications for lower limb and foot morbidity. The review indicates that SLE affects lower limb and foot morbidity but the scale of these problems and effective management of them is unclear.

Purpose Foot health interventions such as foot orthoses for people with rheumatoid arthritis (RA) reduce pain, improve function and improve overall quality of life. Additionally, patient education (PE) is considered essential in achieving good outcomes with interventions such as foot orthoses, footwear and self-care. The aim of this literature review was to identify evidence in relation to the content, use and delivery of PE in the management of RA foot problems. Methods An electronic search of the following databases was performed: PubMed, CINAHL, AMED, Medline and the Cochrane Library, between March 2000 and March 2010. In order to be included, studies had to be published in English, involve adults (>18 years) with RA, and assist in answering the research question. No publications regarding PE for the management of foot health-related problems in RA were found. However, other key terms emerged that embraced PE for people with RA and informed a further search. Thirty-two papers met the inclusion criteria and were reviewed with regard to the subject area, content of the paper, methodological issues and their key findings. Results The present review provides evidence for the effectiveness of PE for people with RA delivered via a staged approach, with the content and timing of education provision being driven by the needs of the patient. Conclusions The effect of PE delivered from a podiatric context needs to be explored, and the nature and requirements of PE for individuals with RA-related foot problems from a patient and practitioner perspective requires investigation. Alternative and innovative ways of providing PE and, potentially, self-management need to be investigated and defined. Copyright © 2011 John Wiley & Sons, Ltd. [ABSTRACT FROM AUTHOR]

Background: Autologous bone graft is the so-called gold standard for reconstruction of bone defects and nonunions. The most frequent complication is donor site pain. The iliac crest is a common source for autologous bone graft. The purpose of this study was to determine whether a continuous infusion of 0.5% bupivacaine into the iliac crest harvest site provides pain relief that is superior to the relief provided by systemic narcotic pain medication alone in patients undergoing reconstructive orthopaedic trauma procedures.Methods: A prospective, double-blind randomized study of patients over eighteen years of age who were undergoing harvesting of iliac crest bone graft was conducted. The patients were randomized to the treatment arm (bupivacaine infusion pump) or the placebo arm. Postoperatively, all study patients received morphine sulfate with use of a patient-controlled analgesia pump. The patients recorded the pain at the donor and recipient sites with use of a scale ranging from 0 to 10. The use of systemic narcotic medication was recorded. Independent-samples t tests were used to assess differences in perceived pain relief between the treatment and control groups at zero, eight, sixteen, twenty-four, thirty-two, forty, and forty-eight hours after surgery. Pain was also assessed at two and six weeks postoperatively.Results: Sixty patients were enrolled. Across all data points, except pain at the recipient site at twenty-four hours, no significant differences in the perception of pain were found between the bupivacaine group and the placebo group. On the average, patients in the treatment group reported more pain than those in the control group. No significant difference was found between the two groups with regard to the amount of narcotic medication used.Conclusions: No difference in perceived pain was found between the groups. The results of this small, unstratified study indicate that continuous infusion of bupivacaine at iliac crest bone-graft sites during the postoperative period is not an effective pain-control measure in hospitalized patients receiving systemic narcotic medication.

Background: We conducted a 2-year nutritional intervention among premenopausal women. The goal was to incorporate two daily servings of soya into the regular diet. This report describes the dietary modifications and assesses their nutritional adequacy with regard to major nutrients.Methods: In this analysis of 100 intervention and 106 control subjects, women completed a validated food-frequency questionnaire at baseline; throughout the study, they participated in at least three unannounced 24-h recalls.Results: At randomization, both groups were similar in age and body weight, reported low soya intake, and did not differ by intake of major nutrients and foods. According to the 24-h recalls, women in the intervention group consumed nearly two servings of soya per day, while the control women remained at 0.2 servings. In comparison with the control group, the intervention group consumed fewer dairy products, primarily milk, but also less meat, nuts and seeds. As a result of the dietary modification, the intervention women consumed less-saturated fat and cholesterol and more protein, dietary fibre, calcium and vitamins than the control group.Conclusion: These results suggest that women in the intervention group improved the overall quality of their diet by adding two servings of soya per day.

Background: The potential effectiveness of various donation incentive programs may vary by demographics, first-time or repeat status, and collection site.Study Design and Methods: Attitudes toward future incentives were obtained from a 1998 anonymous survey sent to 92,581 US blood donors. Responses (encouraged, discouraged, no difference) to incentives were compared within demographic groups, donations sites, and between first-time and repeat community whole-blood (WB) donors using chi-square tests and logistic regressions adjusted for sample design.Results: Incentives most likely to encourage donation return among all 45,588 WB respondents were blood credits (61%), cholesterol screening (61%), and prostate-specific antigen (PSA) screening (73% of men). Younger donors (< or = 25 years old) were 4 to 5 times more likely to be encouraged to donate if offered compensatory incentives (tickets to events, discounts or lottery and/or raffle tickets), gifts, or a token of appreciation than were those donors older than 55. This age effect influenced positive attitudes toward incentives in first-time donors and in donors giving at schools, universities, or military sites. Among all donors, up to 7 to 9 percent reported they would be discouraged to return if offered compensatory incentives.Conclusions: Blood credits and cholesterol and PSA screening would be well received at all donation sites. Gifts, compensatory incentives, and tokens of appreciation appeal more to younger donors. These data may allow blood centers to optimize recruitment by tailoring limited incentive resources more effectively. [ABSTRACT FROM AUTHOR]

Background: Understanding blood donor motivations is crucial to improving effectiveness of donor recruitment and retention programs.Study Design and Methods: Data from a 1998 survey of 92,581 U.S. blood donors were used to evaluate factors influencing the decision to donate in various demographic groups. Data were weighted to adjust for response and sample design.Results: Of 52,650 respondents, 45,588 gave whole-blood (WB) donations. Among all demographic groups, the major reasons to donate were altruism (75-87%) and awareness of the need for blood (34-43%). Except for first-time donors and those Conclusion: WB donations appear to be made primarily for altruistic reasons and in response to appeals for blood. Ways to build on this humanitarianism and take advantage of new communication routes, such as e-mail, need to be developed. [ABSTRACT FROM AUTHOR]

Background: Although there have been no well-documented cases of transfusion-transmitted syphilis in more than 30 years, serologic tests for syphilis (STS) continues to be required for donated blood. Previously, the methods for detecting viable spirochetes were dependent on the use of the rabbit infectivity test. DNA PCR and RNA RT-PCR were applied to assess the presence of Treponema pallidum DNA or RNA in blood donors with confirmed-positive results in STS.Study Design and Methods: This case series describes T. pallidum DNA and RNA testing of platelet concentrates prepared from blood donors with reactive results in an automated treponemal screening test and positive test results in the fluorescent treponomal antibody absorption test. The first DNA test was specific for the T. palladium polA gene. The second DNA test was a multiplex PCR using a T. pallidum 47-kDa gene target. The RT-PCR for RNA used T. pallidum 16S rRNA as a template for production of a cDNA target.Results: One hundred sixty-nine samples (including rapid plasma reagin [RPR]+ and RPR-) tested for T. pallidum DNA and/or RNA were negative.Conclusions: A lack of demonstrable T. pallidum DNA or RNA suggests that blood donors with confirmed-positive results in STS are unlikely to have circulating T. pallidum in their blood and that that their blood is unlikely to be infectious for syphilis.

Background: Increased knowledge of HIV transmission and behavioral and test screening may encourage high-risk blood donors to self-defer.Study Design and Methods: Knowledge of HIV transmission and screening and the association with demographics, screening test reactivity, and unreported deferrable risks (UDRs) was assessed by a 1998 anonymous mail survey sent to 92,581 blood donors, of whom 57 percent responded. Groups were compared by using weighted chi-square tests and logistic regression analysis.Results: Four percent of the donors thought that it was very likely or somewhat likely for a person to contract HIV from donating blood, and 20 percent perceived a similar risk from blood transfusion. Only 60 percent of the donors knew that the available screening tests may not detect a recent infection. Thirty-seven percent either did not know or felt it was acceptable to donate blood to obtain HIV testing. Those most likely to answer knowledge questions incorrectly were more likely to have a higher prevalence of test reactivity or UDRs and to be Conclusion: Innovative ways to increase donor understanding of the implications of risk behaviors and the limitations of current screening procedures should be developed. They might prevent high-risk individuals from donating blood. [ABSTRACT FROM AUTHOR]

Background: Screening and confirmatory serologic tests for syphilis are known to generate false-positive results in low-risk populations, which include blood donors. This study assessed whether conditions previously reported to cause biological false-positive (BFP) test results for syphilis are relevant to contemporary syphilis testing of blood donors and the extent to which seropositive donors report a history of syphilis.Study Design and Methods: A history of conditions reported to be associated with BFP syphilis tests or a history of syphilis infection was assessed by a case-control study of donors with reactive and nonreactive automated treponemal test results, using an anonymous mail survey. Analysis of cases was stratified by fluorescent treponemal antibody absorption (FTA-ABS) result.Results: Adjusted ORs (95% CIs) for reported BFP-associated conditions were 1.3 (0.8-2.1) for FTA-ABS-positive cases and 0.8 (0.3-1.9) for FTA-ABS-negative cases. Among responding blood donors, syphilis history was reported in 78 (51%) of 153 FTA-ABS-positive cases, 0 of 142 FTA-ABS-negative cases, and 3 (0.4%) of 716 automated treponemal test (PK-TP)-negative controls.Conclusion: Approximately half of donors with FTA-ABS-positive test results reported a syphilis history. There was no difference between reported BFP conditions for FTA-ABS-positive or FTA-ABS-negative cases and controls. This information may be useful when providing donors with better predonation or post-test counseling information about syphilis testing. [ABSTRACT FROM AUTHOR]

Background: Evaluating plateletpheresis (PPH) and repeat community whole-blood (RWB) donors' responses to donation incentive programs is essential for developing effective donor retention programs.Study Design and Methods: Using data from a 1998 anonymous questionnaire sent to 92,581 US blood donors, the prevalence of unreported deferrable risks, screening test reactivity, and response to incentives were compared in RWB and PPH donors by the use of weighted chi-square tests and logistic regression analyses.Results: From 52,650 respondents, 38,884 RWB and 2,028 PPH donors were identified. Levels of screening test reactivity (1%) and unreported deferrable risks (UDRs, 2-3%) were similar in RWB and PPH donors. RWB and PPH donors were strongly encouraged or discouraged by similar incentives. Of the incentives that would encourage a higher proportion of UDR-free RWB donors to return, cholesterol screening and earning a blood credit appealed to >50 percent. Similar results were obtained for cholesterol screening in PPH donors. Community service or education credits, premarital screening, and cash had limited appeal for PPH and RWB donors, respectively, and would be more likely to differentially encourage donors with a UDR to return.Conclusion: Incentives that were associated with the greatest donor appeal and that minimized the potential recruitment of more risky donors were identified.

Background: It is important to assess the potential efficacy and safety of offering donation incentives as part of recruitment and retention programs.Study Design and Methods: In 1995, 7489 allogeneic donors responded to an anonymous mail survey that inquired about demographics, donation history, infectious disease risks, and the potential appeal of incentives.Results: The projected net effect of offering blood credits and medical testing would be to motivate, respectively, 58 percent and 46 percent of donors to return, whereas offering an item of limited value would motivate 20 percent to do so. First-time and younger donors reported more frequently than repeat or older donors that incentives would appeal to them. Donors attracted by cash were 60 percent more likely to have a risk for transfusion-transmissible infections (p = 0.03). Although not statistically significant, the odds of being an at-risk donor were higher among individuals attracted by tickets to events (OR 1.5) and extra time off work (OR 1.2).Conclusion: These findings suggest that offering blood credits and (though to a lesser extent) items of limited value could be safe and effective strategies for retaining donors. Although medical tests were found to have broad appeal, studies are needed to identify tests in which donors would be most interested. [ABSTRACT FROM AUTHOR]

Context: Persons at risk of human immunodeficiency virus 1 (HIV-1) infection, have been classified incorrectly as HIV infected because of Western blot results, but the frequency of false-positive Western blot results is unknown.Objectives: To determine the frequency of false-positive HIV-1 Western blot results in US blood donors and to make projections to other screened populations. Secondarily, to validate an algorithm for evaluating possible false-positive cases.Design: A retrospective cohort study of HIV-1 enzyme immunoassay (EIA) and Western blot results from large blood donor screening programs in which donors with suspected false-positive Western blot results underwent HIV-1 RNA polymerase chain reaction (PCR) testing and follow-up HIV-1 serology.Setting: Five US blood centers participating in the Retrovirus Epidemiology Donor Study.Participants: More than 5 million allogeneic and autologous blood donors who successfully donated blood at 1 of the 5 participating centers from 1991 through 1995.Main Outcome Measures: Rate of false positivity by Western blot and true HIV-1 infection status as determined by HIV-1 RNA PCR and by serologic follow-up of blood donors more than 5 weeks after donation.Results: Of 421 donors who were positive for HIV-1 by Western blot, 39 (9.3%) met the criteria of possible false positivity because they lacked reactivity to p31. Of these, 20 (51.3%) were proven by PCR not to be infected with HIV-1. The false-positive prevalence was 4.8% of Western blot-positive donors and 0.0004% (1 in 251000) of all donors (95% confidence interval, 1 in 173000 to 1 in 379000 donors).Conclusions: A false diagnosis of HIV-1 infection can result from the combination of EIA and Western blot testing in blood donor and other HIV-1 screening programs. Individuals with a positive Western blot result lacking the p31 band should be counseled that, although they may be HIV infected, there is uncertainty about this conclusion. These individuals should be further evaluated by RNA PCR testing (if feasible) and HIV serologic analysis on a follow-up sample. [ABSTRACT FROM AUTHOR]

Background: Despite the widespread induction of miR-146a during the innate immune response little is known regarding its biogenesis, function and mechanism. We have therefore examined the role of miR-146a during the interleukin (IL)-1beta-stimulated IL-6 and IL-8 release and proliferation in primary human airway smooth muscle (HASM) cells.Methods: HASM cells were isolated from human lung re-section, cultured to a maximum of 3 - 6 passages and then exposed to IL-1beta. miR-146a expression were determined by qRT-PCR, IL-6 and IL-8 release by ELISA and proliferation using bromodeoxyuridine incorporation. The role of NF-kappaB and the MAP kinase pathways was assessed using pharmacological inhibitors of IKK2 (TPCA-1), JNK (SP600125), p38 MAP kinase (SB203580) and MEK-1/2 (PD98059). miR-146a function was determined following transfection of HASM with inhibitors and mimics using Amaxa electroporation.Results: IL-1beta induced a time-dependent and prolonged 100-fold induction in miR-146a expression, which correlated with release of IL-6 and IL-8. Exposure to IL-1beta had no effect upon HASM proliferation. Pharmacological studies showed that expression of primary miR-146a was regulated at the transcriptional levels by NF-kappaB whilst post-transcriptional processing to mature miR-146a was regulated by MEK-1/2 and JNK-1/2. Functional studies indicated that IL-1beta-induced miR-146a expression does not negatively regulate IL-6 and IL-8 release or basal proliferation. However, inhibition of IL-1beta-induced IL-6 and IL-8 release was observed at the super-maximal intracellular miR-146a levels obtained by transfection with miR-146a mimics and indicates that studies using miRNA mimics can produce false positive results. Mechanistic studies showed that in the presence of super-maximal levels, the action of miR-146a mimics was mediated at a step following IL-6 and IL-8 mRNA transcription and not through down-regulation of IL-1 receptor associated kinase 1 (IRAK-1) and TNF receptor-associated factor 6 (TRAF6) protein expression, two predicted miR-146a targets involved in IL-1beta signalling.Conclusions: We have shown that IL-1beta-induced miR-146a expression in HASM and that this was regulated at the transcriptional level by NF-kappaB and at the post-transcriptional level by the MEK-1/2 and JNK-1/2. Unlike previous reports, studies using miRNA inhibitors showed that miR-146a expression did not regulate IL-6 and IL-8 release or proliferation and suggest miR-146a function and mechanism is cell-type dependent.
