Adult native septic arthritis: a review of 10 years of experience and lessons for empirical antibiotic therapy.

Objectives To review the epidemiology of native septic arthritis to establish local guidelines for empirical antibiotic therapy as part of an antibiotic stewardship programme. Methods We conducted a 10 year retrospective study based on positive synovial fluid cultures and discharge diagnosis of septic arthritis in adult patients. Microbiology results and medical records were reviewed. Results Between 1999 and 2008, we identified 233 episodes of septic arthritis. The predominant causative pathogens were methicillin-susceptible Staphylococcus aureus (MSSA) and streptococci (respectively, 44.6% and 14.2% of cases). Only 11 cases (4.7%) of methicillin-resistant S. aureus (MRSA) arthritis were diagnosed, among which 5 (45.5%) occurred in known carriers. For large-joint infections, amoxicillin/clavulanate or cefuroxime would have been appropriate in 84.5% of cases. MRSA and Mycobacterium tuberculosis would have been the most frequent pathogens that would not have been covered. In contrast, amoxicillin/clavulanate would have been appropriate for only 75.3% of small-joint infections (82.6% if diabetics are excluded). MRSA and Pseudomonas aeruginosa would have been the main pathogens not covered. Piperacillin/tazobactam would have been appropriate in 93.8% of cases (P < 0.01 versus amoxicillin/clavulanate). This statistically significant advantage is lost after exclusion of diabetics (P = 0.19). Conclusions Amoxicillin/clavulanate or cefuroxime would be adequate for empirical coverage of large-joint septic arthritis in our area. A broad-spectrum antibiotic would be significantly superior for small-joint infections in diabetics. Systematic coverage of MRSA is not justified, but should be considered for known carriers. These recommendations are applicable to our local setting. They might also apply to hospitals sharing the same epidemiology.

Safety of a new algorithm for the management of childhood illness (Almanach) to improve quality of care and rational use of drugs

Introduction New evidence from randomized controlled and etiology of fever studies, the availability of reliable RDT for malaria, and novel technologies call for revision of the IMCI strategy. We developed a new algorithm based on (i) a systematic review of published studies assessing the safety and appropriateness of RDT and antibiotic prescription, (ii) results from a clinical and microbiological investigation of febrile children aged <5 years, (iii) international expert IMCI opinions. The aim of this study was to assess the safety of the new algorithm among patients in urban and rural areas of Tanzania.Materials and Methods The design was a controlled noninferiority study. Enrolled children aged 2-59 months with any illness were managed either by a study clinician using the new Almanach algorithm (two intervention health facilities), or clinicians using standard practice, including RDT (two control HF). At day 7 and day 14, all patients were reassessed. Patients who were ill in between or not cured at day 14 were followed until recovery or death. Primary outcome was rate of complications, secondary outcome rate of antibiotic prescriptions.Results 1062 children were recruited. Main diagnoses were URTI 26%, pneumonia 19% and gastroenteritis (9.4%). 98% (531/541) were cured at D14 in the Almanach arm and 99.6% (519/521) in controls. Rate of secondary hospitalization was 0.2% in each. One death occurred in controls. None of the complications was due to withdrawal of antibiotics or antimalarials at day 0. Rate of antibiotic use was 19% in the Almanach arm and 84% in controls.Conclusion Evidence suggests that the new algorithm, primarily aimed at the rational use of drugs, is as safe as standard practice and leads to a drastic reduction of antibiotic use. The Almanach is currently being tested for clinician adherence to proposed procedures when used on paper or a mobile phone

Binary proposal for assessing quality of Open Access Institutional Repositories : the case of Spanish repositories

The reason for this study is to propose a new quantitative approach on how to assess the quality of Open Access University Institutional Repositories. The results of this new approach are tested in the Spanish University Repositories. The assessment method is based in a binary codification of a proposal of features that objectively describes the repositories. The purposes of this method are assessing the quality and an almost automatically system for updating the data of the characteristics. First of all a database was created with the 38 Spanish institutional repositories. The variables of analysis are presented and explained either if they are coming from bibliography or are a set of new variables. Among the characteristics analyzed are the features of the software, the services of the repository, the features of the information system, the Internet visibility and the licenses of use. Results from Spanish universities ARE provided as a practical example of the assessment and for having a picture of the state of the development of the open access movement in Spain.

Characteristics and quality of care of diabetic patients residing int the canton of Vaud

Introduction: Within the framework of the «Programme cantonal Diabète», we aimed at collecting data to 1) describe the population of diabetic patients in the canton of Vaud, and 2) assess the quality of their care. Methods: A cross-sectional study was conducted in the fall of 2011. Out of 140 randomly selected community pharmacies registered in the canton of Vaud, 56 accepted to participate in patients' recruitment. Noninstitutionalized adult diabetic patients (disease duration >12 months) visiting a pharmacy with a prescription for oral anti-diabetic drugs, insulin, glycemic strips or glucose meter were eligible. Patients not residing in the canton of Vaud, not speaking and understanding French well enough, presenting obvious cognitive impairment, and women with gestational diabetes, were excluded. Using a self-administered questionnaire, data was collected on patients' characteristics and diabetes as well as various process (e.g. recommended annual screenings) and outcomes quality of care indicators. Descriptive analyses were performed. Results: A total of 406 patients with diabetes participated. Mean age was 64 years, 41% were women and 63% were married. Patients reported type 1, 2 and other types of diabetes in 13%, 69% and 19%, respectively. They were treated with oral anti-diabetic drugs, insulin or both in 50%, 23% and 27% of the cases. Half of the patients did not report any diabetes-related complication. Glucose self-monitoring was reported by 82% of the patients. Of those who were aware of HbA1C (n = 218), 98% reported at least one HbA1C control during the last 12 months. During that same time frame, 97% and 95% reported at least one blood pressure and weight measure, 94% reported having had a cholesterol check, 74%, 68% and 64% had eyes, feet and urine screening respectively. 62% of the patients had been immunized against influenza. At least 76% of the patients had a minimum of 5 of the 7 described process indicators performed during the last 12 months. Among patients who knew the value (n = 145), mean HbA1C was 7.4 (SD 1.2). Conclusion: This study targeting community-based diabetic patients shows that while routine clinical and laboratory tests were annually performed in the vast majority of patients, feet and urine screening, as well as influenza immunization, were less often reported by patients. The proportion of patients with diabetes having had at least 5 out of the 7 annual screenings performed was nevertheless very high.

Food allergy: Evaluation of the quality of life in Swiss children

Background: Food allergy in children, an increasingly prevalent disease, significantly affects the quality of life. Its impact can be analyzed by the recently validated French version of the Food Allergy Quality of Life Questionnaire (FAQLQ). Objectives: The aim of our study was to evaluate the quality of life in a small sample of Swiss children with IgE-mediated food allergy. Methods: Information were collected with the questionnaire among 0-12 years old children and their parents during a scheduled allergy visit, and analysed in term of emotional impact, food anxiety and social and food limitations. Patients were divided according to the questionnaire in three age groups: group 1 from 0 to 3 years, group 2 from 4 to 6 years and group 3 from 7 up to 12 years. Results: 30 food allergic patients were included, with a girl/boy ratio of 1:1.14. Median age was 6 years. 56% suffered from or had a history of eczema, 23% of rhino-conjunctivitis, 30% of asthma, and 13% reported a drug allergy. None had insect venom allergy. 57% were known to be allergic to one food, 20% to two foods, 20% to 3 foods and 3% had 3 or more food allergies. Tree nuts (51% of all allergies) as well as eggs (28 %) were the major allergies. Emotional impact had a total score of 1.54 but showed differences between age groups. In group 1 it was lower with 0.23, in group 2 the score was 2.03 and 1.77 in group 3. Food anxiety total score was 1.9; 0.76 in group 1, 2.31 in group 2 and 2.23 in group 3. Social and food limitations showed similar results with a total score of 1.73 and 1.23 in group 1, 2.05 in group 2 and 1.68 for group 3. Conclusion: Food allergy affects the quality of life of Swiss children. Our preliminary results on a small sample are comparable to previously published data. We show that the impact of food allergy on daily life increases when the child starts school and social activities.

Canakinumab Relieves Symptoms of Acute Flares and Improves Health-Related Quality Of Life (HRQoL) in Difficult-To-Treat Gouty Arthritis Patients by Suppressing Inflammation: Results of a Randomized, Dose-Ranging Study

RATIONALE:We investigated the impact of canakinumab, a fully human anti-interleukin-1b monoclonal antibody on inflammation and HRQoL in gouty arthritis patients.METHODS: In this 8-week, single-blind, dose-ranging study, patients with acute gouty arthritis flares, unresponsive/intolerant or contraindicated to NSAIDs and/or colchicine were randomized to single subcutaneous canakinumab (10, 25, 50, 90, or 150mg, N5143) or single intramuscular triamcinolone acetonide (TA, 40mg, N557). Patients assessed pain (Likert scale), physicians assessed clinical signs of joint inflammation, and HRQoL was recorded using SF-36.RESULTS: At baseline, 98% patients had moderate-to-extreme pain, 85% had moderate/severe joint swelling, 64-79% had elevated inflammatory markers and HRQoL scores indicated impaired physical function. Percentage of patients with no/mild pain was numerically greater in most canakinumab groups vs. TA, 24-72h post-dose; difference significant for 150mg group at these time-points (P<0.05). Canakinumab 150mg was associated with significantly lower Likert scores for tenderness [OR, 3.2; 95% CI, 1.27-7.89; P50.014] and swelling (OR, 2.7; 95% CI, 1.09-6.50, P50.032) at 72h vs. TA; erythema was not different. Median CRP and SAA levels normalized by 7 days post-dose in most canakinumab groups, but remained elevated in TA. Physical function improved at 7 days postdose in all groups, highest improvement for canakinumab 150mg. SF-36 scores for physical functioning and bodily pain with canakinumab 150mg approached US general population scores by 7 days post-dose and exceeded normal values by 8 weeks post-dose.CONCLUSION: Canakinumab 150mg produced significantly greater and rapid pain-relief and improvements in HRQoL vs. TAin acute gouty arthritis patients.

An international validation study of the EORTC brain cancer module (EORTC QLQ-BN20) for assessing health-related quality of life and symptoms in brain cancer patients.

Aims: The psychometric properties of the EORTC QLQ-BN20, a brain cancer-specific HRQOL questionnaire, have been previously determined in an English-speaking sample of patients. This study examined the validity and reliability of the questionnaire in a multi-national, multi-lingual study. Methods: QLQ-BN20 data were selected from two completed phase III EORTC/NCIC clinical trials in brain cancer (N=891), including 12 languages. Experimental treatments were surgery followed by radiotherapy (RT) and adjuvant PCV chemotherapy or surgery followed by concomitant RT plus temozolomide (TMZ) chemotherapy and adjuvant TMZ chemotherapy. Standard treatment consisted of surgery and postoperative RT alone. The psychometrics of the QLQ-BN20 were examined by means of multi-trait scaling analyses, reliability estimation, known groups validity testing, and responsiveness analysis. Results: All QLQ-BN20 items correlated more strongly with their own scale (r>0.70) than with other QLQ-BN20 scales. Internal consistency reliability coefficients were high (all alpha0.70). Known-groups comparisons yielded positive results, with the QLQ-BN20 distinguishing between patients with differing levels of performance status and mental functioning. Responsiveness of the questionnaire to changes over time was acceptable. Conclusion: The QLQ-BN20 demonstrates adequate psychometric properties and can be recommended for use in conjunction with the QLQ-C30 in assessing the HRQOL of brain cancer patients in international studies.

Correlating trainees' translating performance with the quality of their metacognitive self-evaluation

This paper presents a study of correlations between the performance of trainee translators, according to their teacher’s assessment, and the quality of their self-evaluation, according to their answers to metacognitive questionnaires. Two case-studies of two consecutive editions of a course in general translation from German into Spanish are dealt with. The course involved the use of post-translation metacognitive questionnaires designed to help trainees to evaluate their translating. A selection of the questionnaires (from the strongest and the weakest performances by students for each course edition) is considered. The study focuses on one item in these questionnaires that has to do with identifying translation problems and justifying their solutions. An interpretive analysis of the trainees’ answers for this questionnaire item reveals that the best-performing students were more strategically and translationally aware in self-evaluating their own translating. Our conclusions are based on considering six parameters from the analysis of the trainees’ answers, which are tentatively regarded as indicative of the quality of their self-evaluation.

Limestone particle sizes and lighting regimens on egg and bone quality of laying hens

Abstract:The objective of this work was to evaluate the effect of limestone particle sizes in the diet and of lighting regimes on the egg and bone quality and on the performance of commercial laying hens. Three hundred Hissex White layers, at 18 weeks of age, were distributed in a completely randomized design, in a 5×2 factorial arrangement (coarse limestone in the diet at 0, 25, 50, 75, and 100%; with or without artificial light), with five replicates of six birds. No significant interaction was observed between particle sizes and lighting regime for the evaluated parameters. There was no significant effect of coarse limestone level in the diet on the performance and egg quality of hens; however, bone deformity (3.23 to 4.01 mm), strength (5.19 to 6.70 kgf cm-2), and mineral matter (51.09 to 59.61%) improved as the proportion of coarse limestone increased. For lighting regime, the treatment with artificial light yielded higher Haugh unit values (87.17 vs. 85.54) than that with natural light only. Greater limestone particles improve bone quality of laying hens, and the use of artificial light can benefit the albumen quality of the eggs.

Prohexadione calcium on the growth and quality of eggplant seedlings

Abstract:The objective of this work was to evaluate the effects of prohexadione calcium concentrations on the growth and quality of eggplant (Solanum melongena) seedlings. The effects of prohexadione calcium concentrations of 0, 50, 100, or 150 mg L-1 on seedling growth parameters were evaluated in a greenhouse experiment. After the greenhouse experiment, the seedlings were transplanted to the field. During the field experiment, the number of days to flowering, plant height, number of fruits per plant, average fruit weight and yield were evaluated. Both experiments were carried out in a completely randomized design with four replicates. All prohexadione calcium concentrations significantly reduced shoot height and internode length, when compared to the control. The concentrations of 50, 100, and 150 mg L-1 prohexadione calcium reduced shoot height by 27, 32, and 38%, respectively. Prohexadione calcium treatments (except the one with 50 mg L-1) enhanced relative chlorophyll content of leaves in comparison to the control. There were no delays in flowering and no significant differences in number of fruits per plant among treatments with prohexadione calcium. The concentrations of 100 and 150 mg L-1 prohexadione calcium significantly reduced yield per plant and total fruit yield, whereas the concentration of 50 mg L-1 did not cause any change in yield compared to the control. The lowest prohexadione calcium concentration can be used to control excessive elongation of eggplant seedlings without yield loss.

Forage potential and silage quality of four varieties of saccharine sorghum

Abstract: The objective of this work was to evaluate four cultivars of saccharine sorghum (Sorghum bicolor) regarding productivity, chemical composition of plant parts, and quality of the ensiling process. The tested varieties of saccharine sorghum were BRS 506, BRS 508, BRS 509, and BRS 511. The experiment was divided into two trials, which assessed: production, morphological composition, and nutritional quality of the saccharine varieties; and fermentation quality and nutritional value of the silage produced from the saccharine varieties. Of the tested varieties, BRS 509 and BRS 511 showed the highest total dry matter (DM) production. The BRS 508 variety presented the highest in vitro digestibility of the whole plant (70.65% DM). During ensiling, the BRS 509 variety showed the lowest DM loss (8.87%). The highest effluent production was observed for BRS 506 and BRS 508, with yields of 521.87 and 393.16 kg Mg-1 ensiled DM, respectively. The BRS 511 variety is the most recommended because of the best results for plant production and nutritional quality. Regarding the ensiling process, BRS 509 presents the lowest fermentation losses and the highest nutritional value of silage.

Quality of web-based information on bipolar disorder

OBJECTIVE: To evaluate web-based information on bipolar disorder and to assess particular content quality indicators. METHODS: Two keywords, "bipolar disorder" and "manic depressive illness" were entered into popular World Wide Web search engines. Websites were assessed with a standardized proforma designed to rate sites on the basis of accountability, presentation, interactivity, readability and content quality. "Health on the Net" (HON) quality label, and DISCERN scale scores were used to verify their efficiency as quality indicators. RESULTS: Of the 80 websites identified, 34 were included. Based on outcome measures, the content quality of the sites turned-out to be good. Content quality of web sites dealing with bipolar disorder is significantly explained by readability, accountability and interactivity as well as a global score. CONCLUSIONS: The overall content quality of the studied bipolar disorder websites is good.
