The effectiveness of a sequenced biological-physicochemical reactor system for treating sewage was studied. The biological degradation was conducted in a Sequential Batch Reactor, which had innovative features for simplifying the operation and maintenance of the reactor. The reactor was operated at 4, 6, 8, and 12 hr cycle. selleck Up to 82% removal of Chemical Oxygen Demand (COD), 50% removal of Dissolved Organic Carbon (DOC), 45% removal of Total Nitrogen (TN), and 45% removal of Total Phosphorus (TP) were achieved. The treated effluent was further polished in a continuous-flow bipolar-mode electrochemical reactor to remove additional recalcitrant organic matter from the wastewater. The process parameters were optimized using Response Surface Methodology. At the optimum condition (pH = 8.7; Current = 1.0; reaction time = 9.0), up to 90% removal of COD, 67% removal of DOC, 61% removal of TN, and 99.9% removal of TP were achieved in the coupled system. Micropollutants belonging to Pharmaceutically Active Compounds, pesticides, etc., were significantly removed. The coupled system completely removed Salmonella, Pseudomonas, and Staphylococcus. However, coliforms were detected at the outlet samples. A UV or ozone disinfection treatment is recommended for the safe reuse of the treated water for nonpotable purposes. PRACTIONER POINTS Sequential sequential batch reactor-electrochemical reactor process (SBR-ECR) technology is effective for micropollutant removal from sewage. The coupled SBR-ECR system requires less footprint compared to conventional biological systems for wastewater treatment. Carbon material balance study revealed that more than 60% of carbon escapes from wastewater in the form of CO2.

To retrospectively assess the rate of oesophagostomy tube-related complications in azotaemic dogs, the influence of the oesophagostomy tube (o-tube) duration and the therapeutic approach (medical versus haemodialysis) on the complication rate.

Medical records were retrospectively reviewed in order to identify azotaemic dogswhich underwent o-tube placement. o-Tube duration (short-term versus long-term), time of o-tube change, therapeutic approach (medical versus haemodialysis), prevalence of minor (malposition, suture related, inflammation, muco-purulent discharge, abscess) and major (haemorrhage, malposition, obstruction, dislodgement, vomiting of the tube, food coming from the stoma) o-tube-related complications were extracted. Univariate and multivariate logistic regression analysis were performed to identify the risk factors for o-tube-related complications.

Tube-related complications were reported in 74 of 139 dogs (53%). Minor complications were reported in 66 of 74 (89%) and major complications in eight of 74 (11%). In azotaemic dogs, o-tube indwelling time (odds ratio (OR) 1.03; 95% confidence interval (CI) 1.01 to 1.05), and the use of haemodialysis (OR 40.12; 95% CI 9.18 to 175.20) were risk factors for o-tube-related complications.

The majority of o-tube-related complications were minor, and easily manageable, with no need of hospitalisation, tube-removal or euthanasia. In azotaemic dogs, the use of haemodialysis was strongly associated with a higher risk of o-tube-related complications, possibly as a consequence of the presence of the neck bandage.

Wilson disease (WD) is an autosomal recessive disorder caused by mutations in the ATP7B gene. In 1984, Scheinberg and Sternlieb estimated the prevalence of WD to be 130,000. However, recent epidemiological studies have reported increasing prevalence rates in different populations. The carrier frequency of ATP7B variants and the prevalence of WD in the Japanese population have not been reported using multiple databases.

Multiple public databases were used. First, we included mutations in the ATP7B gene that were registered in the Human Gene Mutation Database (HGMD) Professional, where 885 ATP7B variants were identified as pathogenic. Next, we investigated the allele frequencies of these 885 variants in Japanese individuals using the Human Genetic Variation Database (HGVD) and the Japanese Multi Omics Reference Panel (jMorp).

Of the 885 variants of ATP7B, 7 and 12 missense and nonsense variants, 0 and 3 splicing variants, and 0 and 2 small deletions were found in the HGVD and in jMorp, respectively. The total allele frequencies of the ATP7B mutations were 0.011 in the HGVD and 0.014 in the jMorp. According to these data, the carrier frequencies were 0.022 (2.2%) and 0.028 (2.8%), respectively, and patient frequencies were 0.000121 (1.21/10,000 individuals) and 0.000196 (1.96/10,000 individuals), respectively.

This is the first study to report the carrier frequency of ATP7B variants and the prevalence of WD in Japan using multiple databases. The calculated prevalence of WD was comparatively higher than that of previous reports, indicating previous underdiagnosis or the existence of less severe phenotypes.

Evaluation of a computerised electrocardiogram algorithm compared to the interpretation of a team of board-certified veterinary cardiologists.

This was a cross-sectional retrospective cohort study. A total of 399 electronic canine electrocardiogram recordings screened from 1391 electrocardiograms were enrolled in the study. A panel of seven cardiologists, masked to patient information, evaluated electrocardiograms for the following P-wave amplitude and duration; PR-interval; R-wave amplitude; QRS duration; heart rate; mean electrical axis; and final overall diagnosis for the detection of arrhythmia and any abnormal electrocardiogram anomaly.

The sensitivity of the electrocardiogram algorithm for detecting arrhythmias was 99.7% (95% confidence intervals, CI 98.5 to 99.9) and the specificity was 99.5% (95% CI 98.0 to 99.9) compared to the consensus result created by panel of cardiologists. The sensitivity of the algorithm for the detection of any electrocardiogram anomaly, including abnormal measurements, was 71.
