Translation, cultural adaptation to Brazil and validation of the venous leg ulcer quality of life questionnaire (VLU-QoL-Br)

Objetivo:traduzir o instrumento Venous legulcer quality of life questionnaire (VLU-QoL), adaptá-lo culturalmente para o português do Brasil e validá-lo com pacientes do Hospital das Clínicas da Faculdade de Medicina de Botucatu (FMB) da Universidade Estadual Paulista (Unesp). Métodos:o questionário foi traduzido por um tradutor profissional e por dois dermatologistas especialistas na área de úlceras venosas (UV), sendo reformulado em reunião com os três tradutores. O constructo (VLU-QoL-Br) foi submetido a pré-entrevista com 10 portadores de UV para a adaptação da linguagem. Posteriormente, foi aplicado em pacientes do HC-Unesp, e como teste-reteste para verificação de sua reprodutibilidade. Resultados:foram avaliados 82 pacientes, sendo 56 (68%) do sexo feminino. A idade média foi de 67,3 anos. O questionário foi traduzido, adaptado e aplicado aos pacientes. O constructo apresentou alta consistência interna (alfa= 0,94) e adequada correlação item-total. Quando avaliados os 32 retestes, observou-se correlação intraclasse para concordância de 0,78 (p < 0,01), indicando boa reprodutibilidade do constructo. A análise fatorial confirmatória corroborou as dimensões do questionário original: atividades, psicológico e sintomas. Escores do VLU-QoL-Br se associaram, independentemente, à área total das úlceras e a menor escolaridade dos sujeitos (p < 0,01). Conclusão:a tradução, a adaptação e a validação do questionário VLU-Qol-Br demonstrou boa performance psicométrica, permitindo seu uso clínico no Brasil. É importante avaliar seu desempenho em outras regiões e em diferentes amostras de indivíduos.

Quality of life profile and correlated factors in chronic leg ulcer patients in the mid-west of São Paulo State, Brazil

BACKGROUND: Chronic leg ulcer may have an impact on patients' quality of life.OBJECTIVES:This study aimed to identify the impact of leg ulcers on patient's quality of life using the Dermatology Life Quality Index and to define the main factors correlated with this perception.METHOD:Cross-sectional, non-probabilistic sampling study. We included patients with chronic leg ulcers being treated for at least 3 months. A sociodemographic and clinical survey was conducted to assess the profile of the ulcers. We administered a screening for depressive symptoms and the Dermatology Life Quality Index. We performed a descriptive statistical analysis, chi-square test and Mann-Whitney test for categorical data, Pearson for numeric variables, and multiple regression for categorical data.RESULTS:Forty-one patients were assessed. Their mean age was 61.78 years. Venous ulcers (48.8%) were the most prevalent. Seventy-three percent of the sample perceived no impact/low impact on quality of life in the past week, and 26.8% perceived moderate/high impact. A multiple regression analysis identified the causes of lesion, pain related to the ulcers, time of onset, and severity of the depressive symptoms as the variables that had an influence on quality of life.CONCLUSIONS:The majority of the sample perceived low or no impact of the condition on the quality of the life. The variables etiology of the lesion (p<0.001), pain related to the ulcers (p=0.001), time of onset (p=0.006), and severity of the depressive symptoms (p<0.001) had an influence on the quality of life, suggesting the need for further studies with more robust designs to confirm the causal relationship between these characteristics and quality of life.

Identification of blood meal sources of Lutzomyia longipalpis using polymerase chain reaction-restriction fragment length polymorphism analysis of the cytochrome B gene

An analysis of the dietary content of haematophagous insects can provide important information about the transmission networks of certain zoonoses. The present study evaluated the potential of polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analysis of the mitochondrial cytochrome B (cytb) gene to differentiate between vertebrate species that were identified as possible sources of sandfly meals. The complete cytb gene sequences of 11 vertebrate species available in the National Center for Biotechnology Information database were digested with Aci I, Alu I, Hae III and Rsa I restriction enzymes in silico using Restriction Mapper software. The cytb gene fragment (358 bp) was amplified from tissue samples of vertebrate species and the dietary contents of sandflies and digested with restriction enzymes. Vertebrate species presented a restriction fragment profile that differed from that of other species, with the exception of Canis familiaris and Cerdocyon thous. The 358 bp fragment was identified in 76 sandflies. Of these, 10 were evaluated using the restriction enzymes and the food sources were predicted for four: Homo sapiens (1), Bos taurus (1) and Equus caballus (2). Thus, the PCR-RFLP technique could be a potential method for identifying the food sources of arthropods. However, some points must be clarified regarding the applicability of the method, such as the extent of DNA degradation through intestinal digestion, the potential for multiple sources of blood meals and the need for greater knowledge regarding intraspecific variations in mtDNA.

Factors that influence healing of chronic venous leg ulcers: a retrospective cohort

BACKGROUND: Venous ulcers have a significant impact on patient quality of life, and constitute a worldwide public health problem. Treatment is complex, with high failure rates.OBJECTIVES: To identify clinical and therapeutic factors that influence healing of venous ulcers.METHODS: Retrospective cohort study of patients with venous ulcers. Ulcer area was measured at the first visit (T0) and after 6 months (T6) and 1 year (T12). A reduction in ulcer area of 50% or more at T6 and T12 was the outcome of interest, weighted by clinical, demographic and treatment aspects.RESULTS: Ninety-four patients were included (137 ulcers). A reduction in ulcer area of 50% or more was seen in 40.1% of patients (95% CI 31.9 to 48.4%) at T6 and 49.6% (95% CI 41.2 to 58.1%) at T12. Complete healing occurred in 16.8% (95% CI 10.5 to 23.1%) at T6 and 27% (95% CI 19.5 to 39.5%) at T12. The lowest ulcer area reductions at T6 were associated with longstanding ulcer (RR=0.95; 95% CI 0.91 to 0.98), poor adherence to compression therapy (RR=4.04; 95% CI 1.31 to 12.41), and infection episodes (RR=0.42; 95% CI 0.23 to 0.76). At T12, lower reductions were associated with longstanding ulcer (RR=0.95; 95% CI 0.92 to 0.98), longer topical antibiotic use (RR=0.93; 95% CI 0.87 to 0.99), and systemic antibiotic use (RR=0.63; 95% CI 0.40 to 0.99).CONCLUSIONS: Longstanding ulcer, infection, poor adherence to compression therapy, and longer topical and systemic antibiotic use were independently correlated with worse healing rates.

Genetic Parameters for Milk Yield and Lactation Length of Crossbred Buffaloes from Brazil by Bayesian Inference

The objective of the study was to estimate heritability and repeatability for milk yield (MY) and lactation length (LL) in buffaloes using Bayesian inference. The Brazilian genetic improvement program of buffalo provided the data that included 628 females, from four herds, born between 1980 and 2003. In order to obtain the estimates of variance, univariate analyses were performed with the Gibbs sampler, using the MTGSAM software. The model for MY and LL included direct genetic additive and permanent environment as random effects, and contemporary groups, milking frequency and calving number as fixed effects. The convergence diagnosis was performed with the Geweke method using an algorithm implemented in R software through the package Bayesian Output Analysis. Average for milk yield and lactation length was 1,546.1 +/- 483.8 kg and 252.3 +/- 42.5 days, respectively. The heritability coefficients were 0.31 (mode), 0.35 (mean) and 0.34 (median) for MY and 0.11 (mode), 0.10 (mean) and 0.10 (median) for LL. The repeatability coefficient (mode) were 0.50 and 0.15 for MY and LL, respectively. Milk yield is the only trait with clear potential for genetic improvement by direct genetic selection. The repeatability for MY indicates that selection based on the first lactation could contribute for an improvement in this trait.

Genetic Parameter Estimates for Milk Yield and Lactation Length in Buffalo

The objective of this study was to estimate genetic parameters for milk yield at 244 days and lactation length in graded buffalo cows at the El Cangre Cattle Genetic Enterprise. Data were gathered from 2575 lactations, 1377 buffalo cows, 37 milking units and between 2002-2009 calving years. It was employed the Restricted Maximum Likelihood method (REML) for estimating (co) variance components with multi trait model. Average of milk yield at 244 days and lactation length were 864 kg and 240 days, respectively. Heritability was 0.15 for milk yield and 0.13 for lactation length. Genetic correlation between these traits was 0.63. It was concluded that it is necessary to intensify selection and to increase control of the information of the genetic herds to obtain high precision in the estimates and therefore, obtain bigger genetic progress in of this species in our country.

Clinical and Microbiologic Evaluation of Chronic Leg Ulcers: A Cross-sectional Study

OBJECTIVE: This study aimed at evaluating the flora and bacterial load of chronic leg ulcers (CLUs) according to the clinical judgment of colonization or infection.DESIGN: This was an analytical and cross-sectional study.SETTING: This study was conducted in an outpatient wound care unit in the Dermatology Department of the Botucatu School of Medicine-UNESP, Brazil.PARTICIPANTS: The participants were patients with CLUs who did not use systemic antibiotics.METHODS: The ulcers were clinically divided into 3 groups: ulcers with good granulation tissue (GGT), critical colonization (CC), and infection. Secretion was collected from a 1-cm(2) area using a swab and seeded by the semiquantitative method.OUTCOME MEASURES: The main outcome measures were genus and species of the bacteria found in the cultures and result of the semiquantitative culture correlating with the clinical diagnosis of GGT, CC, and infection.MAIN RESULTS: Seventy-seven ulcers were evaluated: 27 with GGT, 29 with CC, and 21 with infection. Gram-negative bacteria were most often found in all groups (81%): Pseudomonas aeruginosa, in granulation and colonized ulcers, and Proteus mirabilis, in infected ulcers. Ulcers from the infected group showed higher bacterial load.CONCLUSIONS: The flora of CLUs was predominantly constituted by gram-negative bacteria, and P aeruginosa was the most prevalent. The bacterial load of infected ulcers was higher as compared with the others, although some ulcers with GGT also presented a high load. The interpretation of microbiologic tests based on the swab techniques and even on semiquantitative analysis requires close clinical correlation.
