RESUMO

BACKGROUND: There is increasing recognition that health care providers need to focus attention, and be judged against, the impact they have on the health outcomes experienced by patients. The measurement of health outcomes as a routine part of clinical documentation is probably the only scalable way of collecting outcomes evidence, since secondary data collection is expensive and error-prone. However, there is uncertainty about whether routinely collected clinical data within electronic health record (EHR) systems includes the data most relevant to measuring and comparing outcomes and if those items are collected to a good enough data quality to be relied upon for outcomes assessment, since several studies have pointed out significant issues regarding EHR data availability and quality. OBJECTIVE: In this paper, we first describe a practical approach to data quality assessment of health outcomes, based on a literature review of existing frameworks for quality assessment of health data and multistakeholder consultation. Adopting this approach, we performed a pilot study on a subset of 21 International Consortium for Health Outcomes Measurement (ICHOM) outcomes data items from patients with congestive heart failure. METHODS: All available registries compatible with the diagnosis of heart failure within an EHR data repository of a general hospital (142,345 visits and 12,503 patients) were extracted and mapped to the ICHOM format. We focused our pilot assessment on 5 commonly used data quality dimensions: completeness, correctness, consistency, uniqueness, and temporal stability. RESULTS: We found high scores (>95%) for the consistency, completeness, and uniqueness dimensions. Temporal stability analyses showed some changes over time in the reported use of medication to treat heart failure, as well as in the recording of past medical conditions. Finally, the investigation of data correctness suggested several issues concerning the characterization of missing data values. Many of these issues appear to be introduced while mapping the IMASIS-2 relational database contents to the ICHOM format, as the latter requires a level of detail that is not explicitly available in the coded data of an EHR. CONCLUSIONS: Overall, results of this pilot study revealed good data quality for the subset of heart failure outcomes collected at the Hospital del Mar. Nevertheless, some important data errors were identified that were caused by fundamentally different data collection practices in routine clinical care versus research, for which the ICHOM standard set was originally developed. To truly examine to what extent hospitals today are able to routinely collect the evidence of their success in achieving good health outcomes, future research would benefit from performing more extensive data quality assessments, including all data items from the ICHOM standards set and across multiple hospitals.

RESUMO

Renewable energy can assist the management of the effects of population growth and rapid economic development on the sustainability of animal husbandry. The primary aim of renewable energy is to minimize the use of fossil fuels via the creation of environmentally friendly energy products from depleted fossil fuels. Digesters that treat swine manure are extensively used in treatment systems; and inclusion of swine carcasses can increase the organic loading rate (OLR) thereby improving biogas yield and productivity on farms. However, the characteristics of the components including animal residues, proteins, lipids, remains of undigested feed items, antimicrobial drug residues, pathogenic microorganisms and nutrient contents, are complex and diverse. It is therefore necessary to manage the anaerobic process stability and digestate purification for subsequent use as fertilizer. Efficient methane recovery from residues rich in lipids is difficult because such residues are only slowly biodegradable. Pretreatment can promote solubilization of lipids and accelerate anaerobic digestion, and pretreatments can process the swine carcass before its introduction onto biodigesters. This review presents an overview of the anaerobic digestion of swine manure and carcasses. We analyze the characteristics of these residues, and we identify strategies to enhance biogas yield and process stability. We consider energy potential, co-digestion of swine manure and carcasses, physical, chemical, and biological pretreatment of biomass, sanitary aspects of swine manure and co-digestates and their recycling as fertilizers.

RESUMO

OBJECTIVE: There is a close relationship between excess adiposity and cardiovascular disease. Although body mass index (BMI) is the most used approach to estimate excess weight, other anthropometric indices have been developed to measure total body and abdominal adiposity. Here, our objective was to assess the usefulness of these anthropometric indices to detect subclinical atheromatous disease. METHODS: A cross-sectional study with 6,809 middle-aged subjects (mean age, 57 [53-63] years) with low to moderate cardiovascular risk from the ILERVAS project. Measures of total body fat (BMI, Clínica Universidad de Navarra - Body Adiposity Estimator [CUN-BAE], and Deurenberg's formula) and central adiposity (waist and neck circumferences, conicity index, waist-to-height ratio, Bonora's equation, the A body adiposity index, and body roundness index) were performed in all participants. Bilateral carotid and femoral ultrasound vascular studies allowed the identification of subjects with plaque. -Results: All measured indices were significantly higher in males with subclinical carotid or femoral plaques (p ≤ 0.021 for all). Also, a positive and significant correlation between all indices and the number of affected territories was found (p ≤ 0.013 for all). From the ROC analysis, all measurements identified patients with asymptomatic atheromatosis but none of them helped make clinical decisions. Regarding females, the results were less conclusive. CONCLUSION: Obesity indices are related to subclinical atheromatosis, especially in men, in a large cohort of middle-aged subjects. However, the indices could not detect the presence of arterial plaque, so, when used in isolation, are unlikely to be decisive.

RESUMO

There is a close relationship between lifestyle behaviors and excess adiposity. Although body mass index (BMI) is the most used approach to estimate excess weight, other anthropometric indices have been developed to measure total body and abdominal adiposity. However, little is known about the impact of physical activity and adherence to a Mediterranean diet on these indices. Here we report the results of a cross-sectional study with 6672 middle-aged subjects with low to moderate cardiovascular risk from the Ilerda Vascular (ILERVAS) project. The participants' adherence to physical activity (International Physical Activity Questionnaire short form) and MedDiet (Mediterranean Diet Adherence Screener) was evaluated. Measures of total adiposity (BMI, Clínica Universidad de Navarra-Body Adiposity Estimator (CUN-BAE), and Deurenberg's formula), central adiposity (waist and neck circumferences, conicity index, waist to height ratio, Bonora's equation, A body adiposity index, and body roundness index), and lean body mass (Hume formula) were assessed. Irrespective of sex, lower indices of physical activity were associated with higher values of total body fat and central adiposity. This result was constant regardless of the indices used to estimate adiposity. However, the association between MedDiet and obesity indices was much less marked and more dependent on sex than that observed for physical activity. Lean body mass was influenced by neither physical activity nor MedDiet adherence. No joint effect between physical activity and MedDiet to lower estimated total or central adiposity indices was shown. In conclusion, physical activity is related to lower obesity indices in a large cohort of middle-aged subjects. MedDiet showed a slight impact on estimated anthropometric indices, with no joint effect when considering both lifestyle variables. ClinTrials.gov Identifier: NCT03228459.

RESUMO

AIMS: To assess the relationship between storage-predominant LUTS and healthcare resource consumption and cost among males in Spain. METHODS: In this non-interventional, cross-sectional study, urologists enrolled males with storage-predominant LUTS and recorded the consumption of healthcare resources (medical visits, diagnostic tests/monitoring, treatment, and hospitalizations) within the previous 6 months. The cost of healthcare resources was calculated from unit costs extracted from a Spanish eHealth database. Severity of LUTS was assessed by the Bladder Self-Assessment Questionnaire (BSAQ) and patients were stratified by symptom score (<6 or ≥6) to assess the relationship between LUTS severity and healthcare resource consumption and cost. RESULTS: Among 610 enrolled patients (BSAQ symptom score <6, n = 191; BSAQ symptom score ≥6, n = 419), the majority (87.7%) consumed healthcare resources during the previous 6 months in the form of medical visits (86.2%), diagnostic tests/monitoring (83.4%), and treatment (85.9%). Patients with BSAQ symptom scores ≥6 used more healthcare resources compared with patients with BSAQ symptom scores <6. The most common treatments for LUTS were α-blockers used as monotherapy (n = 229 [37.5%]) or in combination with antimuscarinics (n = 227 [37.2%]). The estimated median annual cost was €1070 per patient, consisting of diagnostic tests/monitoring (54.6%), medical visits (20.5%), and treatment (29.6%), and was higher in patients with BSAQ symptom score ≥6 (€1127) than in patients with BSAQ symptom score <6 (€920; P < 0.001). CONCLUSIONS: More severe LUTS are associated with higher healthcare consumption and cost. These findings highlight the importance of symptom management in LUTS patients to help minimize healthcare consumption and cost.

RESUMO

Although all chromite ore processing residue (COPR) sites near residential neighborhoods in Jersey City, New Jersey have undergone remediation, recent studies found widespread, but low levels of hexavalent chromium (Cr(+6)) in house dust both in Jersey City and in communities with no known sources of Cr(+6). This study was designed as a follow-up to determine whether there is an association between current Cr(+6) levels in house dust and urinary chromium concentrations in young children. Dust samples (N=369) were collected from 123 homes. The median Cr(+6) concentration was 3.3 µg/g (mean±SD 5.2±7.5) and the median Cr(+6) loading was 1.1 µg/m(2) (1.9±3.1). These levels were not elevated compared with previously reported levels in background communities (median concentration=3.5 µg/g; median loading=2.8 µg/m(2)). Urinary chromium concentrations were measured in spot urine samples collected from 150 children, ages 3 months to 6 years. The median uncorrected urinary chromium concentration was 0.19 µg/l (0.22±0.16). Current urinary chromium concentrations were significantly lower than those previously reported before and during remediation (t-test; P<0.001). Urinary chromium concentrations were not significantly higher in homes with high (75th or 90th percentile) Cr(+6) dust levels (concentration or loading) compared with other homes. Multiple linear regression was used to examine the relationship between Cr(+6) levels (concentration and loading) in house dust and urinary chromium concentrations (uncorrected and specific gravity corrected). Contrary to pre-remediation studies, we did not find a positive association between Cr(+6) levels in house dust and urinary chromium concentrations. The findings indicate that current Cr(+6) levels in house dust are not positively associated with children's chromium exposure as measured by urinary chromium, and the children's exposure to Cr(+6) in house dust is below the level that could be identified by urine sampling.

RESUMO

When analysing food samples for enteric viruses, a sample process control virus (SPCV) must be added at the commencement of the analytical procedure, to verify that the analysis has been performed correctly. Samples can on occasion arrive at the laboratory late in the working day or week. The analyst may consequently have insufficient time to commence and complete the complex procedure, and the samples must consequently be stored. To maintain the validity of the analytical result, it will be necessary to consider storage as part of the process, and the analytical procedure as commencing on sample receipt. The aim of this study was to verify that an SPCV can be recovered after sample storage, and thus indicate the effective recovery of enteric viruses. Two types of samples (fresh and frozen raspberries) and two types of storage (refrigerated and frozen) were studied using Mengovirus vMC0 as SPCV. SPCV recovery was not significantly different (P > 0.5) regardless of sample type or duration of storage (up to 14 days at -20 °C). Accordingly, samples can be stored without a significant effect on the performance of the analysis. The results of this study should assist the analyst by demonstrating that they can verify that viruses can be extracted from food samples even if samples have been stored.

RESUMO

The microbiological standard for detection of Listeria monocytogenes relies on several cultural steps and requires 7 days for final confirmation, and due to food distribution and market demands, there is a prevailing need for an alternative methodology for its detection. The aim of this study was to compare different detection strategies based on real-time PCR (RTi-PCR) for a rapid and sensitive detection in an ample range of food products: raw pork and poultry meat, raw sheep milk cured cheese, and ready to eat lettuce salad. Four parameters were evaluated to reduce the time and cost for final results: the initial sample size (25 and 50 g), the dilution of the sample (1:3; 1:5 and 1:10 dilutions in Half Fraser broth), the incubation times (6, 10 and 24h) and the bacterial DNA extraction (simple boiling of the culture after washing the bacterial pellet, the use of the Chelex resin, and a commercial silica column. The results obtained demonstrate that a combination of an incubation in Half-Fraser for 24h of a 1:10 diluted-25 g-sample coupled to a DNA extraction using a commercial silica column and a real-time PCR assay detected down to 2-4 L. monocytogenes CFU per sample in less than 27 h in different types of food products. This RTi-PCR-based method is fully compatible with the ISO standard, providing results more rapidly and cost-effectively. The results were confirmed in a large number of naturally contaminated food samples with at least the same analytical performance as the reference method.

En la evaluación al finalizar el prelenguaje el 94% de los niños tuvo un desarrollo del lenguaje acorde a su edad, el 4% un desarrollo normal retardado y un 2% se retrasó. Estos presentaron como causa secundaria Curso atípico del desarrollo, Hipoacusia neurosensorial bilateral profunda y Epilepsia. Predominó la buena eficacia al tratamiento. Conclusiones: de este estudio se concluye que con la puesta en práctica del programa de estimulación se logró que los niños alcanzaran un desarrollo del lenguaje en correspondencia a su edad, mejorando su calidad de vida.


Introduction: in presppech formation the sensory stimulation received by the child is essential. Objective: to implement a stimulating program for prevention and timely treatment of speech disorders in children with perinatal risk factors, so that it allows a proper development of basic elements of oral communication, starting from the evaluation of each prespeech sub-stage. Material and methods: an observational, descriptive, longitudinal, prospective study was carried out, at the Neurodevelopment Service of Abel Santamaría Teaching Hospital of Pinar del Río, in the period 2010-11, taking data from logophoniatric medical records processed into the statistical system InfStat 1.0. The universe consisted of 183 children, and the sample of 142 children conforming to the inclusion criteria. Results: the sample showed 68 prenatal risk factors, 234 perinatals, and 150 neonatal. In the evaluation at the end of prespeech, 94% of the children had speech development in correspondence with their ages, and 2% got retarded. These presented as secondary cause atypical course of development, deep bilateral neurosensory hypoacusis, and epilepsy. The treatment was very efficient. Conclusions: with this study we concluded that the implantation of the stimulating program allowed the children to reach speech development in accordance with their ages, improving their quality of life.

RESUMO

This work reports the development of a simple, reliable and automated method based on LC-MS/MS for the quantitative determination of benzimidazole residues and some of their metabolites in milk. The method involves the use of an extraction cartridge coupled on-line to the chromatographic system for the clean-up of the milk samples, efficiently eliminating matrix macromolecules and providing appropriate selectivity for the determination of such compounds. In the online method developed here, only a reduced manual sample manipulation was required (protein precipitation and filtration) prior to injection into the chromatographic system. The limits of detection of the target anthelmintics ranged from 0.1 to 0.8 ng mL(-1) in milk samples, these values being below the maximum residue limit established for these compounds. The whole method developed was validated in real samples according to the requirements set by the Commission Decision 2002/657/EC. The optimized method was successfully applied to commercial and raw milk samples of different origin demonstrating that the proposed method may find application in routine laboratory analyses of food control safety.

RESUMO

We evaluated the capacity of the Mycoplasma agalactiae p40 gene as a diagnostic marker for contagious agalactia in sheep by quantitative real-time PCR. The p40 gene encodes an immunodominant adhesin that plays a key role in cytoadhesion of M. agalactiae. The assay was 100% specific, with an analytical sensitivity of 1 genome equivalent (GE), a quantification that is highly linear (R(2) > 0.992) and efficient (PCR efficiency, >0.992) over a 6-log dynamic range, down to 10 GE. We evaluated the capacity of the assay to detect Mycoplasma agalactiae in 797 milk samples (373 raw sheep milk samples from refrigerated tanks of different farms and 424 milk samples from individual sheep of a flock positive for M. agalactiae). In parallel, we also tested the samples by using microbiological isolation coupled with microscopy identification and by a PCR method recommended by the World Organization for Animal Health. While our assay was able to detect 57 (15.28%) positive samples of the 373 milk samples from different farms, identification by microbiological isolation coupled with microscopy detected only 36 (9.65%) samples, and the conventional PCR detected 31 (8.31%) samples. These findings showed that our assay based on the p40 gene is more specific and sensitive for the detection of M. agalactiae in actual natural samples and, thus, can be a promising alternative tool for diagnosis and epidemiological studies of M. agalactiae infection.

RESUMO

We developed and assessed real-time PCR (RTi-PCR) assays for the detection and quantification of the food-borne pathogen Listeria monocytogenes and the closely related nonpathogenic species L. innocua. The target genes were hly and iap for L. monocytogenes and lin02483 for L. innocua. The assays were 100% specific, as determined with 100 Listeria strains and 45 non-Listeria strains, and highly sensitive, with detection limits of one target molecule in 11 to 56% of the reactions with purified DNA and 3 CFU in 56 to 89% of the reactions with bacterial suspensions. Quantification was possible over a 5-log dynamic range, with a limit of 15 target molecules and R(2) values of >0.996. There was an excellent correspondence between the predicted and the actual numbers of CFU in the samples (deviations of <23%). The hly-based assay accurately quantified L. monocytogenes in all of the samples tested. The iap-based assay, in contrast, was unsuitable for quantification purposes, underestimating the bacterial counts by 3 to 4 log units in a significant proportion of the samples due to serovar-related target sequence variability. The combination of the two assays enabled us to classify L. monocytogenes isolates into one of the two major phylogenetic divisions of the species, I and II. We also assessed the new AmpliFluor technology for the quantitative detection of L. monocytogenes by RTi-PCR. The performance of this system was similar to that of the TaqMan system, although the former system was slightly less sensitive (detection limit of 15 molecules in 45% of the reactions) and had a higher quantification limit (60 molecules).
