A portion of horses vaccinated against WNV may respond poorly. Vaccination every 6 months may be indicated in certain horses and in areas of high vector activity. Other preventative methods such as mosquito control are warranted to prevent WNV infection in horses.
Abstract. Previously published studies have neither used nor reported the results of an indirect enzymelinked immunosorbent assay (iELISA) to measure serologic responses in natural outbreaks of strangles. The concept of using serologic responses to identify persistent carriers of Streptococcus equi has been proposed but not scientifically evaluated. The specific aims of the current study were to determine the duration and level of truncated fibrinogen-binding protein-specific (SeM allele 1) antibody production in ponies involved in a natural outbreak of strangles and to determine if test results from this serologic iELISA could predict persistent carrier status. Serologic samples were obtained before and after an outbreak of naturally occurring strangles infection. Persistent carriers of S. equi were identified via culture and polymerase chain reaction (PCR) testing of lavage fluid collected from the guttural pouches and nasopharynx or swabs of the nasopharynx after recovery from acute disease and at postmortem examination. Logistic regression analysis was used to determine if an association existed between serologic response and persistent carrier state. The ELISA reported in the current study definitively confirmed a recent exposure to S. equi. However, the measured serologic response did not predict carrier status in this strangles outbreak. Therefore, a gutturalpouch endoscopy with subsequent culture or PCR testing to detect S. equi remains the most accurate method available for the identification of persistent carriers.
ObjectivesTo identify the frequency of postoperative complications, including problems identified by patients and complications occurring after discharge from hospital. To identify how these impact on quality of life (QoL) and the patient’s perception of the success of their treatment.DesignData from three prospective sources: surgical audit, a telephone interview (2 weeks after discharge) and a patient-focused questionnaire (2 months after surgery) were retrospectively analysed.SettingDunedin Hospital, Dunedin, New Zealand.ParticipantsOf the 500 patients, 100 undergoing each of the following types of surgeries: anorectal, biliary, colorectal, hernia and skin.Primary and secondary outcome measuresThe primary outcomes were complications and the 36-item Short Form Health Survey (SF-36). Secondary outcomes included the patient’s ratings of their treatment and a questionnaire-derived patient satisfaction score.Results226 patients reported a complication; there were 344 separate complications and 411 reports of complications (16% of complications were reported on more than one occasion). The audit, telephone interview and questionnaire captured 12.6%, 36.3% and 51% of the 411 reports, respectively. Patients with complications had a lower SF-36 Physical Composite Summary (PCS) score (48.5 vs 43.9, p=0.021) and a lower Patient Satisfaction Score (85.6 vs 74.6, p<0.001). Rating of information received, care received, symptoms experienced, QoL and satisfaction with surgery were all significantly worse for patients with complications. On linear regression analysis, surgical complications, American Society of Anaesthesiologists score and age all made a similar contribution to the SF-36 PCS score, with standardised beta coefficients between 0.19 and 0.21.ConclusionsFollowing surgery, over 40% of patients experienced complications. The QoL and satisfaction score were significantly less than for those without complications. The majority of complications were diagnosed after discharge from hospital. Taking more notice of the patient perspective helps us to identify problems, to understand what is important to them and may suggest ways to improve perioperative care.
Background: A local health authority in Canada implemented its own Antimicrobial Stewardship Program (ASP) which provide guidelines to clinicians to utilize when treating infectious diseases such as community-acquired pneumonia (CAP). Objectives: The primary objective is to describe antibiotic usage patterns at the community hospital’s emergency department (ED) and to analyze the patterns in relation to ASP goals of reducing risk of infections, adverse drug events and antibiotic resistance, and to identify potential areas of improvement. Methods: This retrospective chart review included 156 adult patients with a diagnosis of CAP admitted to a community hospital ED from December 1, 2015 to November 30, 2016. Results: 50.6% patients were prescribed moxifloxacin across all severity of CAP patients. Low and moderate severity CAP patients were most often prescribed antibiotic duration > 7 days. In low, moderate and high severity CAP patients who were treated using ceftriaxone, 100%, 88.9% and 66.6% patients were treated with ceftriaxone 2000 mg daily respectively. Conclusions: Antibiotic prescribing patterns suggest fluoroquinolones were frequently being over-prescribed, ceftriaxone dosages were often too high, and duration of antibiotics for low and moderate severity CAP were too long. More efforts are needed to promote appropriate antibiotic usage and optimize patient care.
A postpartum mare and foal were presented for evaluation of fever and lethargy in the mare. The mare was diagnosed with endometritis and initially responded well to treatment. On the second day of hospitalization, the mare developed renal insufficiency characterized by oliguria, azotemia, hemolysis, and thrombocytopenia. Concurrently, the foal developed rapidly progressive central nervous system signs culminating in refractory seizures. Both animals failed to respond to treatment and were euthanized. Thrombotic microangiopathy involving glomeruli was evident on microscopic examination of the mare's kidneys. Microscopic evidence of brain edema was the principal postmortem finding in the foal. No specific etiology was confirmed in either case. Notably, Escherichia coli 0103:H2 was isolated from the mare's uterus and the gastrointestinal tracts of both animals. To the authors' knowledge, this is the first report in which an organism implicated as a cause of hemolytic-uremic syndrome was isolated from an animal with clinical signs and postmortem findings consistent with the disease.
SummaryOver the last decade there has been a major reassessment of the classification of inherited corneal disease. In this presentation I discuss our program to genotype all patients attending our tertiary referral center who have suspected monogenic corneal disease. This has enabled us to distinguish the phenotypes of several closely related dystrophies as well as identify a small number of patients who have previously been misclassified. Some patients with important systemic associations have been identified and referred for further investigation and management. Finally, patients without changes in the genes commonly associated with corneal dystrophy have been selected for further evaluation. The impact of this for clinical care will be discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
