ANÁLISE DE CÁLCIO EM DIFERENTES TIPOS DE BEBIDAS
Foram analisadas infusos de duas amostras de chá preto, uma amostra de orange pekoe tipo
Assam, duas amostras de chá mate tostado, quatro amostras de erva-mate e uma amostra de
café liofilizado, dissoluções à quente de uma amostra de leite em pó desnatado, uma amostra de
leite em pó integral e uma amostra de alimento com proteína isolada de soja instantâneo. Estas
amostras foram adquiridas em supermercados da Região Metropolitana de Curitiba; com a
finalidade de verificar e comparar os teores de cálcio desses diferentes tipos de bebidas. Nas
determinações foi utilizada metodologia oficial e todas as análises em triplicata. Os teores de cálcio
obtidos foram analisados estatisticamente: as amostras de chá preto apresentaram o menor teor
de cálcio que variou de 16,94 mg/100 mL até 24,84 mg/100 mL. As amostras de chámate tostado
mostraram valores mais elevados, sendo que uma delas acusou 78,39 mg/100 mL, equivalendo

CALCIUM ANALYSIS IN DIFFERENT DRINKS
Abstract
Two samples of black tea, a sample of orange pekoe variety Assam, two samples of toasted tea, four
varieties of erva-mate, a freeze dried coffee sample were prepared by hot infusion, samples of
skimmed powder milk and powder wholemilk and one instant isolated soy protein sample were
prepared in hot water. These samples were purchased in markets in Curitiba to identify and analyze
calcium content in comparison with Official methodologies were used and for all determinations
three analyses were done. Black tea samples resulted minor calcium content (16.94 to 24.84 mg/
100 mL). Toasted tea resulted major calcium amount with 78.39 mg/100 mL, similar to calcium
amount of powder and soy milk. Erva-mate samples are comparable to calcium content in powder
milk. Freeze dried coffee presented high calcium amount (141.68 mg/100 mL)
Rationale and design of the hip fracture accelerated surgical treatment and care track (hip attack) trial : A protocol for an international randomised controlled trial evaluating early surgery for hip fracture patients
Introduction Annually, millions of adults suffer hip fractures. The mortality rate post a hip fracture is 7%-10% at 30 days and 10%-20% at 90 days. Observational data suggest that early surgery can improve these outcomes in hip fracture patients. We designed a clinical trial - HIP fracture Accelerated surgical TreaTment And Care tracK (HIP ATTACK) to determine the effect of accelerated surgery compared with standard care on the 90-day risk of all-cause mortality and major perioperative complications. Methods and analysis HIP ATTACK is a multicentre, international, parallel group randomised controlled trial (RCT) that will include patients ≥45 years of age and diagnosed with a hip fracture from a low-energy mechanism requiring surgery. Patients are randomised to accelerated medical assessment and surgical repair (goal within 6 h) or standard care. The co-primary outcomes are (1) all-cause mortality and (2) a composite of major perioperative complications (ie, mortality and non-fatal myocardial infarction, pulmonary embolism, pneumonia, sepsis, stroke, and life-threatening and major bleeding) at 90 days after randomisation. All patients will be followed up for a period of 1 year. We will enrol 3000 patients. Ethics and dissemination All centres had ethics approval before randomising patients. Written informed consent is required for all patients before randomisation. HIP ATTACK is the first large international trial designed to examine whether accelerated surgery can improve outcomes in patients with a hip fracture. The dissemination plan includes publishing the results in a policy-influencing journal, conference presentations, engagement of influential medical organisations, and providing public awareness through multimedia resources.

A fluorinated analogue of marine bisindole alkaloid 2,2-bis(6-bromo-1h-indol-3-yl)ethanamine as potential anti-biofilm agent and antibiotic adjuvant against staphylococcus aureus
Methicillin resistant Staphylococcus aureus (MRSA) infections represent a major global healthcare problem. Therapeutic options are often limited by the ability of MRSA strains to grow as biofilms on medical devices, where antibiotic persistence and resistance is positively selected, leading to recurrent and chronic implant-associated infections. One strategy to circumvent these problems is the co-administration of adjuvants, which may prolong the efficacy of antibiotic treatments, by broadening their spectrum and lowering the required dosage. The marine bisindole alkaloid 2,2-bis(6-bromo-1H-indol-3-yl)ethanamine (1) and its fluorinated analogue (2) were tested for their potential use as antibiotic adjuvants and antibiofilm agents against S. aureus CH 10850 (MRSA) and S. aureus ATCC 29213 (MSSA). Both compounds showed antimicrobial activity and bisindole 2 enabled 256-fold reduction (ΣFICs = 0.5) in the minimum inhibitory concentration (MIC) of oxacillin for the clinical MRSA strain. In addition, these molecules inhibited biofilm formation of S. aureus strains, and compound 2 showed greater eradicating activity on preformed biofilm compared to 1. None of the tested molecules exerted a viable but non-culturable cells (VBNC) inducing effect at their MIC values. Moreover, both compounds exhibited no hemolytic activity and a good stability in plasma, indicating a non-toxic profile, hence, in particular compound 2, a potential for in vivo applications to restore antibiotic treatment against MRSA infections
Screening of mutations in the CFTR gene in 1195 couples entering assisted reproduction technique programs.
Genetic testing of the cystic fibrosis transmembrane conductance (CFTR) gene is currently performed in couples undergoing assisted reproduction techniques (ART), because of the high prevalence of healthy carriers in the population and the pathogenic relationship with congenital bilateral absence of vas deferens (CBAVD). However, discordant data have been reported concerning the usefulness of this genetic test in couples with no family history of cystic fibrosis (CF). In this study, we report the results of CFTR molecular screening in 1195 couples entering ART. Genetic testing was initially carried out in a single partner of each couple. CFTR mutations were detected in 55 subjects (4.6%), a percentage that overlaps with the one reported in the general population. However, significantly higher frequencies of were found in CBAVD individuals (37.5%) and in males with nonobstructive azoospermia (6.6%). The 5T allele was found in 78 patients (6.5%). This figure was again significantly different in males with nonobstructive-azoospermia (9.9%) and in those with CBAVD (100%). All together, 139 subjects (11.6%) had either a CFTR mutation or the 5T allele. Subsequent molecular analysis of their partners disclosed a CFTR mutation or 5T allele in nine cases (6.5%). However, none of these couples had CFTR alterations in both members, a CFTR mutation being invariably present in one partner and the 5T allele in the other. In order to improve genetic counselling of these couples, the TG-M470V-5T association was analyzed, and a statistically significant relationship between 12TG-V470 and CBAVD was detected
