Point-of-care ultrasonography to predict fluid responsiveness in children: A systematic review and meta-analysis.

BACKGROUND: Point-of-care ultrasonography (POCUS) is proposed as a valuable method for hemodynamic monitoring and several ultrasound-based predictors of fluid responsiveness have been studied. The main objective of this study was to assess the accuracy of these predictors in children. METHODS: PubMed, Embase, Scopus, ClinicalTrials.gov, and Cochrane Library databases were searched for relevant publications through July 2022. Pediatric studies reporting accuracy estimates of ultrasonographic predictors of fluid responsiveness were included since they had used a standard definition of fluid responsiveness and had performed an adequate fluid challenge. RESULTS: Twenty-three studies involving 1028 fluid boluses were included, and 12 predictors were identified. A positive response to fluid infusion was observed in 59.7% of cases. The vast majority of participants were mechanically ventilated (93.4%). The respiratory variation in aortic blood flow peak velocity (∆Vpeak) was the most studied predictor, followed by the respiratory variation in inferior vena cava diameter (∆IVC). The pooled sensitivity and specificity of ∆Vpeak were 0.84 (95% CI, 0.76-0.90) and 0.82 (95% CI, 0.75-0.87), respectively, and the area under the summary receiver operating characteristic curve (AUSROC) was 0.89 (95% CI, 0.86-0.92). The ∆IVC presented a pooled sensitivity and specificity of 0.79 (95% CI, 0.62-0.90) and 0.70 (95% CI, 0.51-0.84), respectively, and an AUSROC of 0.81 (95% CI, 0.78-0.85). Significant heterogeneity in accuracy estimates across studies was observed. CONCLUSIONS: POCUS has the potential to accurately predict fluid responsiveness in children. However, only ∆Vpeak was found to be a reliable predictor. There is a lack of evidence supporting the use of POCUS to guide fluid therapy in spontaneously breathing children.

Isolation and Chemical Characterization of Antifungal, Antioxidant, and Anti-Inflammatory Compounds from Centrosema coriaceum using GC/MS, UFLC-QTOF-MS, and FACE.

In recent years, natural products with biological activities have been increasingly researched. The elucidation of phytoconstituents is necessary for the development of drugs as a natural alternative for the treatment of various diseases. The work aimed to evaluate in vitro and in silico bioactivities of hexane (CCHE) and methanol (CCME) fractions of ethanolic extract from Centrosema coriaceum Benth (Fabaceae) leaves and elucidate their phytoconstituents. CCHE and CCME showed antifungal activity for Candida glabrata (MIC of 1000 µg/mL) with fungistatic effect and action in cell envelope by sorbitol and ergosterol assays. CCHE and CCME presented promising antioxidant activity against the DPPH radical with IC50 of 13.61±0.50 and 6.31±0.40 µg/mL, respectively, and relative antioxidant activity (RAA%) of 45.77±3.61/ 28.53±2.25 % for CCHE and 82.18±2.25/51.99±3.23 % for CCME when compared to rutin and quercetin, respectively. Moreover, these fractions demonstrated promising results for the inhibition of lipid peroxidation by ß-carotene/linoleic acid assay. For anti-inflammatory and cytotoxicity activities, CCHE and CCME significantly inhibited the production of nitric oxide and TNF-α, without toxicity on murine intraperitoneal macrophages, respectively. Esters, alkanes, steroids, tocopherols, and terpenes were identified in CCHE by GC/MS. Flavonoids, phenolic acids, and disaccharides were detected in CCME by UFLC-QTOF-MS and FACE. Furthermore, rutin was purified from CCME. In silico predictions evidenced that compounds present in both fractions have high affinity to the fungal membrane besides antioxidant and anti-inflammatory activities. Based on these observations, CCHE and CCME have a noteworthy potential for the design of novel antifungal and anti-inflammatory agents that should be explored in future studies.

Carotid doppler ultrasonography as a method to predict fluid responsiveness in mechanically ventilated children.

AIMS: The aim of this study was to investigate whether respiratory variations in carotid and aortic blood flows measured by Doppler ultrasonography could accurately predict fluid responsiveness in critically ill children. METHODS: This was a prospective single-center study including mechanically ventilated children who underwent fluid replacement at the discretion of the attending physician. Response to fluid load was defined by a stroke volume increase of more than 15%. Maximum and minimum values of velocity peaks were determined over one controlled respiratory cycle before and after volume expansion. Respiratory changes in velocity peak of the carotid (∆Vpeak_Ca) and aortic (∆Vpeak_Ao) blood flows were calculated as the difference between the maximum and minimum values divided by the mean of the two values and were expressed as a percentage. RESULTS: A total of 30 patients were included, of which twelve (40%) were fluid responders and 18 (60%) non-responders. Before volume expansion, both ∆Vpeak_Ca and ∆Vpeak_Ao were higher in responders than in non-responders (17.1% vs 4.4%; p < .001 and 22.8% vs 6.4%; p < .001, respectively). ∆Vpeak_Ca could effectively predict fluid responsiveness (AUC 1.00, 95% CI 0.88-1.00), as well as ∆Vpeak_Ao (AUC 0.94, 95% CI 0.80-0.99). The best cutoff values were 10.6% for ∆Vpeak_Ca (sensitivity, specificity, positive predictive value and negative predictive value of 100%) and 18.2% for ∆Vpeak_Ao (sensitivity, 91.7%; specificity, 88.9%; positive predictive value, 84.6%; negative predictive value, 94.1%). Volume expansion-induced changes in stroke volume correlated with the ∆Vpeak_Ca and ∆Vpeak_Ao before volume expansion (ρ of 0.70 and 0.61, respectively; p < .001 for both). CONCLUSIONS: Analysis of respiratory changes in carotid and aortic blood flows are accurate methods for predicting fluid responsiveness in children under invasive mechanical ventilation.

Combining UFLC-QTOF-MS analysis with biological evaluation of Centrosema coriaceum (Fabaceae) leaves.

Centrosema coriaceum Benth belongs to Fabaceae family and have few studies of biological activity and chemical composition. Thus, the aims of this work were to determine chemical profile of the ethanolic extract of C. coriaceum leaves (CCE) by UFLC-QTOF-MS and to evaluate its in vitro biological potential. CCE showed MIC value of 1000 µg/mL against Candida glabrata (fungistatic effect) and high affinity in cell envelope by increasing cell permeability in nucleotide leakage, sorbitol and ergosterol assays. CCE showed antioxidant activity in all assays performed. For the anti-inflammatory and cytotoxicity activities, CCE, at all tested concentrations, significantly inhibited the production of nitric oxide and did not decrease J774A.1 cell viability below 70%. Finally, rutin, kaempferol-3O-rutinoside, caffeic acid, and sucrose were identified in CCE by UFLC-QTOF-MS. These results suggest, for the first time, that C. coriaceum has interesting antifungal, antioxidant, and anti-inflammatory activities.

Antifungal efficacy of atorvastatin-containing emulgel in the treatment of oral and vulvovaginal candidiasis.

Drug repositioning has been an important ally in the search for new antifungal drugs. Statins are drugs that act to prevent sterol synthesis in both humans and fungi and for this reason they are promissory candidates to be repositioned to treat mycoses. In this study we evaluated the antifungal activity of atorvastatin by in vitro tests to determine the minimum inhibitory concentration against azole resistant Candida albicans and its mechanisms of action. Moreover, the efficacy of both atorvastatin-loaded oral and vaginal emulgels (0.75%, 1.5% and 3% w/w) was evaluated by means of in vivo experimental models of oral and vulvovaginal candidiasis, respectively. The results showed that atorvastatin minimal inhibitory concentration against C. albicans was 31.25 µg/ml. In oral candidiasis experiments, the group treated with oral emulgel containing 3.0% atorvastatin showcased total reduction in fungal load after nine days of treatment. Intravaginal delivery atorvastatin emulgel showed considerable effectiveness at the concentration of 3% (65% of fungal burden reduction) after nine days of treatment. From these findings, it is possible to assert that atorvastatin may be promising for drug repositioning towards the treatment of these opportunistic mycoses.

Atorvastatin is a statin drug that presents antifungal activity. This study showed that atorvastatin-containing oral and vaginal emulgels were able to treat vulvovaginal and oral candidiasis of infected animal model. Therefore, we showcased that atorvastatin may be a possible therapeutic agent in order to be a used to control opportunistic mucosal fungal infections caused by Candida albicans.

Paranoid delusional disorder follows social anxiety disorder in a long-term case series: evolutionary perspective.

Social anxiety disorder (SAD) patients may have self-referential ideas and share other cognitive processes with paranoid delusional disorder (PDD) patients. From an evolutionary perspective, SAD may derive from biologically instinctive social hierarchy ranking, thus causing an assumption of inferior social rank, and thus prompting concerns about mistreatment from those of perceived higher rank. This naturalistic longitudinal study followed four patients with initial SAD and later onset of PDD. These four patients show the same sequence of diagnosed SAD followed by diagnosed PDD, as is often retrospectively described by other PDD patients. Although antipsychotic medication improved psychotic symptoms in all patients, those who also had adjunctive serotonin-specific reuptake inhibitors for SAD had much more improvement in both psychosis and social functioning. From an evolutionary perspective, it can be conjectured that when conscious modulation of the SAD social rank instinct is diminished due to hypofrontality (common to many psychotic disorders), then unmodulated SAD can lead to paranoid delusional disorder, with prominent ideas of reference. Non-psychotic SAD may be prodromal or causal for PDD.

Evaluation of Seroprevalence and Risk Factors of Heartworm Infection for Dogs in Rio de Janeiro with Access to Veterinary Care.

Heartworm infection is a chronic disease with clinical signs and effects ranging from an asymptomatic condition to severe disease and death. The prevalence of heartworm disease in the state of Rio de Janeiro has been reported to be high (21.3%). The present study was conducted to evaluate the seroprevalence and risk factors of heartworm infection for the canine population with access to veterinary services in different areas of the state of Rio de Janeiro, Brazil. A total of 1787 canine blood samples were obtained from 135 practices across 8 different areas of Rio de Janeiro state (Rio de Janeiro municipality, São Gonçalo municipality, Niterói municipality, Baixada Fluminense, and the northern, southern, eastern, and mountainous areas) and tested for the presence of Dirofilaria immitis antigens and antibodies against several tick-borne disease pathogens using a commercial immunochromatography technique (Vetscan® Flex 4 Rapid Test; Zoetis; NJ USA). Pet owners reported living conditions, physical characteristics, demographics, and clinical signs for evaluation of risk factors for heartworm infection. Only two evaluated risk factors were shown to enhance the risk for D. immitis infection, including having a short hair coat vs. having a medium or long hair coat (OR 2.62) or positive for antibodies to tick-borne disease parasites (OR 3.83). Clinical signs reported for dogs with heartworm disease were typical for that condition. The overall prevalence of heartworm disease in the state was 8.2%, ranging from 2.4% in the mountainous region to 29.4% in the eastern area. It could not be determined if veterinarians were not diligent about dispensing heartworm preventatives or if poor levels of compliance by dog owners were responsible for higher infection rates in some areas of the state.

Aerobic exercise 3 times per week in adult rats did not influence the progression of periodontal disease.

Introduction: Physical exercise has proven efficacy in the prevention and treatment of chronic diseases, and its anti-inflammatory effect has been evaluated as a potential preventive factor in the progression of periodontal disease, in addition to improving physiological parameters. Methods: To test this hypothesis regarding its preventive factor, we evaluated the effects of aerobic training on the progression of periodontal disease in 8-month-old Wistar rats (n = 44). The animals underwent a swimming protocol lasting six weeks, with periodontal disease induced by ligature in the fifth week, totaling fourteen days of ligature placement. Anthropometric parameters were measured for subsequent calculations of BMI and Lee's Index. Interleukin-1ß testing was performed to measure serum inflammatory parameters, and alveolar bone loss was measured using images to calculate the area of loss. Results: The trained animals showed no significant differences compared to the non-trained animals in terms of anthropometric measures. Regarding the area of bone loss, although there were significant differences between the groups with and without periodontal disease, exercise did not demonstrate an impact on rats with the disease. IL-1ß analysis did not detect any measurable values in the samples in either group. Discussion: These findings indicate that the applied exercise protocol was not sufficient to attenuate the progression of periodontal disease. This study did not find an effective impact of physical exercise on the analyzed parameters; however, the results are important in highlighting that the experimental animal model for inducing periodontal disease is efficient, which may encourage further investigations to determine factors that can attenuate its progression. Similarly, the application or development of new exercise protocols that can benefit and enrich the discussion on its positive effects in this disease is important, as there is already evidence suggesting an effective relationship between exercise and disease progression.

Pharmacological investigation of antioxidant and anti-inflammatory activities of aqueous extract from Mitracarpus frigidus (Rubiaceae).

OBJECTIVES: This study aimed to evaluate the potential of aqueous extract from Mitracarpus frigidus aerial parts (MFAq) in the treatment of inflammation and oxidative stress, as well as to characterize its chemical constituents. METHODS: Total phenolic and flavonoid contents were determined, and phytoconstituents were detected by ultra-fast liquid chromatography/quadrupole-time-of-flight tandem mass spectrometry (UFLC-QTOF-MS). The antioxidant activity was evaluated by DPPH, TAC and ß-carotene/linoleic acid assays. In-vitro anti-inflammatory activity, cell viability and cell cycle were performed in J774A.1 cell line. In-vivo anti-inflammatory activity was investigated by two ear oedema assays (croton oil and phenol). KEY FINDINGS: Chlorogenic acid, clarinoside, quercetin-hexosylpentoside, rutin, kaempferol-3-O-rutinoside, kaempferol-rhamnosylhexoside, quercetin-pentosylrhamnosylhexoside, harounoside, 2-azaanthraquinone and sucrose were identified by UFLC-QTOF-MS. MFAq showed antioxidant activity, which was positively correlated to the content of phenolic compounds. MFAq significantly inhibited the production of nitric oxide, did not decrease viability in MTT assay (all concentrations) and showed no changes in membrane permeability and cell cycle of J774A.1 cell line. Furthermore, MFAq showed a reduction in ear oedema in all tested doses. CONCLUSION: MFAq was effective in some antioxidant and inflammatory parameters, in the experimental conditions that were used in the study. This is the first report of chemical composition and bioactivities from this extract.

Pharmacological investigation of antioxidant and anti-inflammatory activities of leaves and branches extracts from Plinia cauliflora (Jaboticaba).

ETHNOPHARMACOLOGICAL RELEVANCE: Among all native Brazilian plant species, Plinia cauliflora (DC.) Kausel (Jaboticaba), is well known for producing "superfruits", due to their high phenolic content and antioxidant property. The fruit has astringent characteristics, and it is popularly known for the treatment of diarrhea, rash, and intestinal inflammation. However, there are only a few studies on the use of leaves and branches of this species in the literature, mainly to treat oxidative stress and inflammation. AIM OF THE STUDY: The present study aimed to investigate the antioxidant and anti-inflammatory potential of leaves and branches extracts from P. cauliflora. MATERIAL AND METHODS: The phytochemical analysis of P. cauliflora extracts was performed by the total phenolic, flavonoid, and tannin dosage method. Moreover, the compounds were identified by HPLC-MS-Q-TOF. Antioxidant capacity was determined by DPPH, ß-carotene/linoleic acid system, MDA formation, and phosphomolybdenum assays. In vitro and in vivo anti-inflammatory activities of P. cauliflora were evaluated by the reduction of nitric oxide in the J774A.1 cell line and inhibition of ear edema in mice, respectively. RESULTS: The ethanolic extract of the leaves exhibited greater flavonoid content whereas the ethanolic extract of the branches showed higher tannins content. Twenty-two and seventeen compounds were identified by HPLC-MS-Q-TOF in the leaves and branches, respectively, being tellimagrandin I, castalagin, and valoneic acid dilactone reported for the first time in P. cauliflora. The antioxidant potential of extracts was confirmed through different oxidation pathways from oxidizing radicals, which might be related to the presence of phenolic compounds. For the anti-inflammatory assay, the leaves and branches extracts showed promising results, with a reduction of nitric oxide ear edema inhibition around 95% and 80%, respectively. CONCLUSIONS: Herein, the great biological potential of leaves and branches extracts from P. cauliflora was highlighted. These parts of the plant are underused and poorly reported in the literature, especially for the antioxidant and anti-inflammatory activities.

Tetracarboxy-phthalocyanines: From excited state dynamics to photodynamic inactivation against Bovine herpesvirus type 1.

Herein we present the excited state dynamic of zinc and aluminum tetracarboxy-phthalocyanines (ZnPc and AlPc) and its application in the photodynamic inactivation (PDI) of Bovine herpesvirus type 1 (BoHV-1) in vitro. The excited state dynamic provides valuable data to describe the excited state properties of potential optical limiters and/or photosensitizers (PSs), such as: the excited state cross-sections, fluorescence lifetime and triplet state quantum yield. The excited state characterization was performed using three different Z-scan techniques: Single Pulse, White Light Continuum and Pulse Train. Considering the photodynamic inactivation of BoHV-1, an initial viral suspension containing 105.75TCID50/mL was incubated with the PSs for 1h at 37°C under agitation and protected from light. The samples were placed in microtiter plates and irradiated (180mW/cm2). During irradiation, a sample was taken every 15min and the viability of the virus was evaluated. The results show that both phthalocyanines were efficient against viruses. However, a higher photodynamic efficiency was observed by ZnPc, which can be attributed to its higher triplet and singlet quantum yields. The results presented here are important for animal health (treatment of BoHV-1) and also open up a field of studies to use AlPc and ZnPc as potential agents against a wide range of microorganisms of veterinary interest.

Photodynamic evaluation of tetracarboxy-phthalocyanines in model systems.

The present work reports the synthesis, photophysical and photochemical characterization and photodynamic evaluation of zinc, aluminum and metal free-base tetracarboxy-phthalocyanines (ZnPc, AlPc and FbPc, respectively). To evaluate the possible application of phthalocyanines as a potential photosensitizer the photophysical and photochemical characterization were performed using aqueous (phosphate-buffered solution, PBS) and organic (dimethyl sulfoxide, DMSO) solvents. The relative lipophilicity of the compounds was estimated by the octanol-water partition coefficient and the photodynamic activity evaluated through the photooxidation of a protein and photohemolysis. The photooxidation rate constants (k) were obtained and the hemolytic potential was evaluated by the maximum percentage of hemolysis achieved (Hmax) and the time (t50) to reach 50% of the Hmax. Although these phthalocyanines are all hydrophilic and possess very low affinity for membranes (log PO/W=-2.0), they led to significant photooxidation of bovine serum albumin (BSA) and photohemolysis. Our results show that ZnPc was the most efficient photosensitizer, followed by AlPc and FbPc; this order is the same as the order of the triplet and singlet oxygen quantum yields (ZnPc>AlPc>FbPc). Furthermore, together, the triplet, fluorescence and singlet oxygen quantum yields of zinc tetracarboxy-phthalocyanines suggest their potential for use in theranostic applications, which simultaneously combines photodiagnosis and phototherapy.

Synthesis and biological evaluation against Mycobacterium tuberculosis and Leishmania amazonensis of a series of diaminated terpenoids.

We report the synthesis of a series of diaminated terpenoids containing, as side-chain of the diamine core, the "head-to-tail" prenyl derivatives, with amino amino spacers of variable length. In vitro biological activity of these compounds was evaluated against Mycobacterium tuberculosis and Leishmania amazonensis, and the structure-activity relationships are discussed. Different biological results were observed depending on the terpenic side-chain length. The best results were obtained for trans,trans-farnesol derivatives. Moreover, these results demonstrated that the stereochemistry of the double bond could play an important role in determining antitubercular and antileishmanial activities of these compounds.

Retalho de Bernard-Burow unilateral com "cutback" de mucosa jugal para tratamento de tumor de lábio inferior: relato de caso / Bernard-Burow flap unilateral with cheek mucosa "cutback" for treatment of lower lip tumor: a case report

O câncer de lábio corresponde a 25-30% de todos os cânceres de boca, sendo mais frequente o de lábio inferior. O carcinoma de células escamosas (CCE) é o subtipo mais incidente, estando o tabagismo como um dos principais fatores de risco. O relato demonstra técnica simples e efetiva para tratamento cirúrgico de CCE no lábio inferior de paciente tabagista. A realização de retalho unilateral de Bernard-Burow, mesmo em defeito maior que 50% do diâmetro inicial do lábio, mostrou-se factível. A adição de "cutback" na mucosa e dissecção parcimoniosa por planos pode ter propiciado uma boa evolução estética e funcional, já que determinou alívio na tensão sobre as suturas. A menor complexidade de execução desta reconstrução, se comparada a outras técnicas, pode garantir uma boa alternativa na tentativa de diminuir a morbidade pós-operatória neste tipo de cirurgia.

Lip cancer corresponds to 25-30% of all oral cancers, with the lower lip being more frequent. Squamous cell carcinoma (SCC) is the most common subtype, with smoking as one of the main risk factors. The report demonstrates a simple and effective technique for SCC's surgical treatment on a smoking patient's lower lip. Even in a defect larger than 50% of the initial lip diameter, the unilateral Bernard-Burow flap proved feasible. The addition of "cutback" in the mucosa and parsimonious dissection by planes may have provided a good aesthetic and functional evolution since it determined tension relief on the sutures. The less complex execution of this reconstruction, compared to other techniques, can guarantee a good alternative to decrease postoperative morbidity in this type of surgery.

Condicionamento Cardiorrespiratório de idosos: há diferença em praticante de exercício físico e não praticantes? / Cardiorespiratory fitness in the elderly: is there a difference in physical activity practitioners and nonpractitioners?

As mudanças no sistema cardiorrespiratório são evidentes durante o processo de envelhecimento. A aptidão cardiorrespiratória (ACR) tem sido considerada um dos principais fatores responsáveis pela perda de independência em idosos. OBJETIVO: verificar a capacidade cardiorrespiratória em idosos praticantes e não praticantes de atividade física sistematizada. MÉTODOS: Trata-se de um estudo com delineamento transversal. A amostra foi composta por 30 idosas, do sexo feminino com idade entre 65 a 75 anos independentes, divididas em praticantes e não praticantes de exercício físico. Definiu-se como critério de exclusão da pesquisa ausência das participantes durante o período de coleta dos dados. Como instrumento de coleta utilizou-se o teste de marcha estacionária para a avaliação cardiorrespiratória. O avaliador conta uma passada de cada vez, sendo que só foram computadas as passadas em que o joelho atinja a altura correta ao nível ponto médio entre a patela e a espinha ilíaca ântero-superior. RESULTADOS: obteve como resultado média de 43,40 ± 10,08 para indivíduos não praticantes de exercício físico, com peso corporal de 59,26 ± 10, 09kg. No entanto, para indivíduos praticantes de exercício físico com peso corporal de 69,73 ± 11,48kg obteve-se média de 43,73 ± 9,29 ciclos completos. CONCLUSÃO: Nessa amostra não houve uma diferença da aptidão cardiorrespiratória em idosos praticantes e não praticantes de exercício físico.

Changes in the cardiorespiratory system are evident during the aging process. Cardiorespiratory fitness (ACR) has been considered one of the main factors responsible for the loss of independence in the elderly. AIM: The goal of this study was to verify the cardiorespiratory capacity in elders practitioners and non-practitioners of systematic physical activity. METHODS: This is a cross-sectional study. The sample consisted of 30 elderly women, female aged between 65 and 75 years independent, divided into practitioners and non-practitioners of physical exercise and the absence of participants during the period of data collection was defined as a criterion for exclusion from the research. As a collection instrument, a stationary gait test was used for cardiorespiratory assessment. The evaluator counts one step at a time, and only the steps in which the knee reaches the correct height at the midpoint between the patella and the anterior superior iliac spine will be computed. RESULTS: obtained an average result of 43.40 ± 10.08 for individuals who did not exercise, with a body weight of 59.26 ± 10, 09kg. However, for individuals practicing physical exercise with a body weight of 69.73 ± 11.48kg, an average of 43.73 ± 9.29 complete cycles were obtained. CONCLUSION: In this sample, there was no difference in cardiorespiratory fitness in elderly practitioners and non-practitioners of physical exercise.

[Analysis of similar drug labeling: potential medication errors]. / Análise da rotulagem de medicamentos semelhantes: potenciais erros de medicação.

OBJECTIVE: This study aimed to examine drug packaging and labeling, identifying similarities among them that may lead to medication errors, which may occur by unintentional substitution, in different sectors of the pharmacy of a university hospital in northeastern Brazil. METHODS: Cross-sectional observational study, which included 300 pharmaceutical presentations (150 pairs) that were photographed from May to December 2010. Concordance analysis of data related to the pictures of possibly similar packaging and labels was validated using the Kappa index. RESULTS: Of all drugs evaluated (n = 150), about 43% of "possibly similar drugs" were in the central pharmacy (n = 65) and were related to small-volume parenteral solutions. The strength of interobserver agreement in the category "very similar to each other" was considered "satisfactory" (Kappa = 0584) in 90.66% of the drugs evaluated (n = 136). The overall Kappa analysis of the study was 0.488. Variables with statistical significance were: "same color label or packaging", with the respective percentages for both primary and secondary packaging (52%-44%), p = 0.028; the variable "same color of drug presentation" obtained similar values and statistical significance to the previous variable; for the variable "same arrangement of words", the values found for both packages were close to 50%, p = 0.001; and for the variable "same color of the words", the percentages were: (50.7% - 44%) (p = 0.008). CONCLUSION: Our results indicate similarities related to the labeling of drugs with potential for errors, especially in dispensing, storage, and administration if preventive measures are not adopted.

Re-conhecimento dos pacientes com Acidente Vascular Cerebral por meio de um Programa de Educação Tutorial / Re- cognition of patients with Stroke through a Tutorial Education Program

O acidente vascular encefálico (AVE) é uma importante causa de mortalidade no Brasil e há necessidade de melhor acompanhamento dessa população. O PRÓ/PET-Saúde III, programa do governo federal desenvolvido na Universidade Federal de Minas Gerais (UFMG) pela equipe da ?Urgência e Emergência?, buscou identificar o perfil dos usuários vítima de AVE, em um grande hospital geral de Belo Horizonte. Foram realizadasentrevistas semiestruturadas com usuários diagnosticados abordando aspectos de relevância pessoal e de saúde. Os resultados encontrados revelaram a idade, local de moradia, analfabetismo, etilismo, os tipos de AVE, déficits anteriores, medicamentos utilizados no momento do episódio, medicamentos de uso crônico, comorbidades relacionadas e acompanhamento nas unidades básicas de saúde (UBS). Foi possívelestabelecer uma relação entre os dados demográficos, a ocorrência de AVE e melhor entendimento sobre a organização do sistema de saúde, principalmente no que se refere à prevenção de agravos de doenças crônicas.

The cerebrovascular accident (CVA) is an important cause of mortality in Brazil and, therefore, improved monitoring in this population is needed. The PRÓ/PET-Health III, which is a federal government program developed at the Federal University of Minas Gerais (UFMG) by the ?urgent and emergency? team sought to identify the profile of the program?s users who were victims of CVA in a large general hospital in Belo Horizonte. Semi-structured interviews were conducted with diagnosed users addressing aspects ofpersonal and health relevance. The results included age, place of residence, illiteracy, alcoholism, types of CVA, previous deficits, medicines used at the time of the episode, chronically used medicines, related comorbidities, and follow up at the Basic Health Units (UBS). It was possible to establish a relationship between the demographic data,occurrence of CVA, and better understanding about the health system organization, especially in regards to prevention of aggravations in chronic diseases.

Pharmaceutical care in transplant patients in a university hospital: pharmaceutical interventions

A descriptive and prospective study was conducted on the pharmaceutical care in the post-transplant outpatient clinic of Hospital Universitario Walter Cantidio of Universidade Federal do Ceará (HUWC/UFC), in Fortaleza- Ceará in the period of April to October of 2011. The aim of the present study was to describe the pharmaceutical interventions performed in a Pharmaceutical Care service structured in the liver and kidney transplant outpatient clinic of an academic hospital. The Pharmaceutical interventions (PI) were classified according to Sabater et al.(2005), with significance based on Riba et al.(2000) and the Negative Outcomes associated with Medication (NOM) established at the Third Consensus of Granada. Statistical analyses were performed using the Epi Info v.3.5.1 program and hypothesis tests were done with the SigmaPlot v.10.0 program. A chi-squared (X²) test was utilized for statistical analysis of the sample. A total of 97 patients were followed, where 54 problems related to medications were identified and 139 PI performed. The main PI were in education of the patient about treatment (n=111; 80%) (p<0.05), while the significance of all interventions were appropriate, where 83.4% (n=116) of PI performed in the study period were shown to be "significant" (p<0.05). Through pharmaceutical care, the pharmacist is capable of monitoring the pharmacotherapeutic treatment and intervening when necessary, while being part of the multiprofessional team caring for the transplant patient.

Trata-se de um estudo de descritivo e prospectivo, realizado durante o atendimento farmacêutico nos ambulatórios de pós-transplante do Hospital Universitário Walter Cantídio da Universidade Federal do Ceará (HUWC/UFC), em Fortaleza-Ceará no período de abril a outubro de 2011. O presente trabalho objetiva apresentar as intervenções farmacêuticas realizadas em um serviço de Atenção Farmacêutica (ATENFAR) estruturado nos ambulatórios do transplante hepático e renal de um Hospital Universitário. As intervenções farmacêuticas (IF) foram classificadas de acordo com Sabater et al.(2005), a significância baseadas em Riba et al.(2000) e os Resultados Negativos associados a Medicamentos (RNM) fundamentados no Terceiro Consenso de Granada. As análises estatísticas foram realizadas no programa Epi Info v.3.5.1 e os testes de hipótese foram feitos no programa SigmaPlot v.10.0. O teste estatístico utilizado para análise da amostra foi o qui-quadrado (X²). Foram acompanhados 97 pacientes, identificados 54 problemas relacionados aos medicamentos e realizadas 139 intervenções farmacêuticas. As principais IF realizadas foram na educação do paciente sobre o tratamento (n=111; 80%) (p<0,05), já enquanto a significância todas as intervenções foram apropriadas, sendo que 83,4% (n=116) das IF realizadas no período do estudo mostram ser "significantes" (p<0,05). O farmacêutico, através do exercício da ATENFAR, é capaz de monitorar o tratamento farmacoterapêutico e intervir, quando necessário, integrando-se a equipe multiprofissional no cuidado ao paciente transplantado.
