RESUMO
Adequate protein levels are necessary to maintain strong honey bee [Apis mellifera (L.)] colonies. The aim of this study was to quantify how pollens with different crude protein contents influence protein stores within individual honey bees. Caged bees were fed one of three diets, consisting of high-protein-content pollen, low-protein-content pollen, or protein-free diet as control; measurements were made based on protein content in hemolymph and fat body, fat body weight, and body weight. Vitellogenin in hemolymph was also measured. Bees fed with high crude protein diet had significantly higher levels of protein in hemolymph and fat bodies. Caged bees did not increase pollen consumption to compensate for the lower protein in the diet, and ingesting approximately 4 mg of protein per bee could achieve levels of 20 microg/microl protein in hemolymph. Worker bees fed with low crude protein diet took more time in reaching similar protein content of the bees that were fed with high crude protein diet. The data showed that fat bodies and body weight were not efficient methods of measuring the protein status of bees. The determination of total protein or vitellogenin concentration in the hemolymph from 13-d-old bees and protein concentration of fat bodies from 9-d-old bees could be good indicators of nutritional status of honey bees.

We have previously developed and validated a self-administered questionnaire, modelled after the Systemic Lupus International Collaborating Clinics Damage Index (SDI), the Lupus Damage Index Questionnaire (LDIQ), which may allow the ascertainment of this construct in systemic lupus erythematosus (SLE) patients followed in the community and thus expand observations made about damage. We have now translated, back-translated and adapted the LDIQ to Spanish, Portuguese and French and applied it to patients followed at academic and non-academic centres in North and South America, Portugal and Spain while their physicians scored the SDI. A total of 887 patients (659 Spanish-speaking, 140 Portuguese-speaking and 80 French-speaking patients) and 40 physicians participated. Overall, patients scored all LDIQ versions higher than their physicians (total score and all domains). Infrequent manifestations had less optimal clinimetric properties but overall agreement was more than 95% for the majority of items. Higher correlations were observed among the Spanish-speaking patients than the Portuguese-speaking and French-speaking patients; further adjustments may be needed before the Portuguese and French versions of the LDIQ are applied in community-based studies. The relationship between the LDIQ and other outcome parameters is currently being investigated in a different patient sample.

To assess bladder function in systemic lupus erythematosus (SLE) patients with recurrent urinary tract infections (UTIs). A convenience sample of consecutive patients with SLE (American College of Rheumatology criteria), with recurrent UTIs (>/=3 events in the preceding 12 months), without history of central nervous system involvement, urolithiasis or preceding tuberculosis were studied. Disease activity (SLEDAI-2K), damage (SDI), lower urinary tract symptoms [Pelvic pain and Urgency/Frequency (PUF) and the Interstitial Cystitis Symptom and Problem Index (ICSPI) scales] and Autonomic Symptom Profile (ASP) were assessed. All patients underwent urological examination and urodynamic assessment with cystometry, uroflow, micturition and urethral pressure profile. Ten patients (nine women) were included. The majority of the patients reported urinary symptoms: urgency (n = 8), frequency (n = 8), nocturia (n = 9) and pain (n = 10). The patients had a mean (SD) ICSPI score of 18.4 (9.8), PUF score of 17.4 (5.3) and ASP weighted score of 31.7 (16.1). Abnormal urodynamics findings were identified in seven of the 10 patients, including small bladder capacity (two patients), reduced bladder sensation (four patients), subnormal urinary flow rate (one patient) and a significant amount of residual urine (two patients). The urodynamics findings suggest that bladder dysfunction could be one of the mechanisms involved on the occurrence of recurrent UTIs in patients with SLE. These findings have potential implications for the proper assessment and management of SLE patients with recurrent UTIs. Further studies are needed to corroborate our results.

This study compared the antipyretic effectiveness of acetaminophen, ibuprofen, and dipyrone in young children with fever. The results were based on a modified double-blind, randomized, multinational trial that evaluated 628 febrile children, aged 6 months to 6 years. All three drugs lowered temperature in the 555 patients completing the study. Temperature normalization rates in the ibuprofen and dipyrone groups (78% and 82%, respectively) were significantly higher than the acetaminophen group (68%, P = 0.004). After 4 to 6 hours, mean temperature in the dipyrone group was significantly lower than the other groups, demonstrating longer temperature normalization with dipyrone. All three drugs showed comparable tolerability profiles.
