Over the last 50 years, parenteral nutrition has been recognised as an invaluable and potentially lifesaving tool in the physician's arsenal in the management of patients with intestinal failure or inaccessibility; however, it may also be associated with a number of potentially life-threatening complications. A recent NCEPOD report (2010) identified a number of inadequacies in the overall provision and management of parenteral nutrition and recommendations were made with the aim of improving clinical practice in the future. This paper focuses on the practical aspects relating to parenteral nutrition for adults, including important concepts, such as patient selection, as well as general management. We also explore the various pitfalls and potential complications and how these may be minimised.

OBJECTIVE To describe the technique, clinical findings, and short-term outcome in dogs undergoing laparoscopic-assisted incisional gastropexy with a reusable single-incision surgery port. DESIGN Retrospective case series. ANIMALS 14 client-owned dogs. PROCEDURES Medical records of dogs referred for elective laparoscopic gastropexy between June 2012 and August 2013 were reviewed. History, signalment, results of physical examination and preoperative laboratory testing, surgical procedure, duration of surgery, postoperative complications, duration of hospital stay, and short-term outcome were recorded. All patients underwent general anesthesia and were positioned in dorsal recumbency. After an initial limited laparoscopic exploration, single-incision laparoscopic-assisted gastropexy was performed extracorporeally in all dogs via a conical port placed in a right paramedian location. Concurrent procedures included laparoscopic ovariectomy (n = 4), gastric biopsy (2), and castration (7). Short-term outcome was evaluated. RESULTS Median duration of surgery was 76 minutes (range, 40 to 90 minutes). Intraoperative complications were minor and consisted of loss of pneumoperitoneum in 2 of 14 dogs. A postoperative surgical site infection occurred in 1 dog and resolved with standard treatment. Median duration of follow-up was 371 days (range, 2 weeks to 1.5 years). No dogs developed gastric dilation-volvulus during the follow-up period, and all owners were satisfied with the outcome. CONCLUSIONS AND CLINICAL RELEVANCE Results suggested that single-incision laparoscopic-assisted gastropexy with a reusable conical port was feasible and effective in appropriately selected cases. Investigation of the potential benefits of this reusable port versus single-use devices for elective gastropexy in dogs is warranted.

Oral antiplatelet therapy may require interruption soon after percutaneous coronary intervention (PCI) or acute coronary syndrome. The optimal parenteral antiplatelet bridge strategy with glycoprotein IIb/IIIa inhibitors or cangrelor, a P2Y12 inhibitor, is unclear. We explore real-world use of cangrelor or eptifibatide for antiplatelet bridging at a large tertiary-care center. Thirty-one patients (9 eptifibatide, 20 cangrelor, and 2 both) received bridge therapy from October 2015 to June 2017. Primary bridge therapy indications included surgery (68%), limited enteral access/absorption (16%), and high-perceived bleed risk (16%). Median duration of bridge therapy was 61 (20-100) hours for cangrelor and 83 (19-98) hours for eptifibatide. Severe/life-threatening bleeding or stent thrombosis was not observed. GUSTO-defined bleeding occurred in 30% (cangrelor) and 27% (eptifibatide). Initial dosing errors occurred in 23% of patients. Death during hospitalization occurred in 16% of patients. Parenteral antiplatelet bridging was used for ~3 days in this single-center, tertiary care experience, commonly for unplanned surgery following PCI. Despite high-risk presentations with >15% in-hospital mortality, efficacy profiles were reassuring with no identified stent thrombosis, but bleeding and dosing errors were common. Antiplatelet bridging should only be used in well-selected patients at the appropriate dose for the minimal necessary duration.

The assimilation of carbohydrates, nitrogen compounds, fat and electrolytes during parenteral feeding (PF) of irradiated animals was studied. Rats were subjected to PF from 2nd to 5th day after total gamma irradiation at 750 R, dogs - from 8th to 11th day after irradiation at 300 R. The results are indicative of a satisfactory assimilation of carbohydrates, nitrogen compounds, fat and electrolytes by animals in the cource of PF. The negative nitrogen balance characteristic of irradiated animals was expressed to a lesser degree. A trend to a lower sodium excretion has been observed during PF period

Brachycephalic dogs are at risk for arterial hypertension and obstructive sleep apnea, which are both associated with chronic magnesium (Mg) depletion. To compare the period prevalence of hypomagnesemia between Boxers and Bulldogs presented to a referral teaching hospital. To screen a group of Bulldogs for evidence of hypomagnesemia, and to obtain pilot data regarding the utility of parenteral Mg tolerance testing (PMgTT) in the diagnosis of whole-body Mg deficiency. Chemistry laboratory submissions were retrospectively analyzed for serum total Mg (tMg) in Boxers and Bulldogs. Prospectively, 16 healthy client-owned Bulldogs were enrolled. Retrospective case study. tMg concentrations were compared between Boxers and Bulldogs. Dogs with low serum albumin or high serum creatinine concentrations were excluded. Prospectively, ionized Mg (iMg), tMg, and arterial blood pressure were measured and iMg-to-tMg ratio (iMg : tMg) was calculated. Parenteral Mg tolerance testing (PMgTT) was performed in 3/16 dogs. In the retrospective study, period prevalence of hypomagnesemia was 4.7% in Boxers and 15% in Bulldogs (P = .02). The risk ratio for hypomagnesemia in Bulldogs was 1.8 when compared to Boxers (CI: 1.3-2.7). In the prospective study, iMg was [median (interquartile)] 0.43 (0.42-0.46) mmol/L (reference range 0.4-0.52), tMg was 1.9 (1.8-1.9) mg/dL (reference range 1.9-2.5). iMg : tMg was [mean (±SD)] 0.59 ± 0.04. Percentage retention after PMgTT were 55%, 95%, and 67%, respectively. Mg deficiency is common in Bulldogs and could contribute to comorbidities often observed in this breed. iMg : tMg and PMgTT might prove helpful in detecting chronic subclinical Mg deficiency.

A juvenile Australian shepherd dog exhibited failure to grow, inappetence, weakness, nonregenerative anemia, neutropenia, and cobalamin deficiency. DNA testing confirmed homozygosity of an amnionless mutation (AMN c.3G > A). Clinical signs resolved with supportive care and parenteral cobalamin supplementation. Inherited selective intestinal cobalamin malabsorption requiring lifelong parenteral supplementation should be considered in Australian shepherds, giant schnauzers, border collies, and beagles that fail to thrive.

Gunst, Jan; Van den Berghe, Greet

Feeding guidelines have recommended early, full nutritional support in critically ill patients to prevent hypercatabolism and muscle weakness. Early enteral nutrition was suggested to be superior to early parenteral nutrition. When enteral nutrition fails to meet nutritional target, it was recommended to administer supplemental parenteral nutrition, albeit with a varying starting point. Sufficient amounts of amino acids were recommended, with addition of glutamine in subgroups. Recently, several large randomized controlled trials (RCTs) have yielded important new insights. This review summarizes recent evidence with regard to the indication, timing, and dosing of parenteral nutrition in critically ill patients. One large RCT revealed no difference between early enteral nutrition and early parenteral nutrition. Two large multicenter RCTs showed harm by early supplementation of insufficient enteral nutrition with parenteral nutrition, which could be explained by feeding-induced suppression of autophagy. Several RCTs found either no benefit or harm with a higher amino acid or caloric intake, as well as harm by administration of glutamine. Although unanswered questions remain, current evidence supports accepting low macronutrient intake during the acute phase of critical illness and does not support use of early parenteral nutrition. The timing when parenteral nutrition can be initiated safely and effectively is unclear.

To describe the clinical findings and short-term outcome in 7 dogs and 1 cat undergoing single-incision laparoscopic-assisted intestinal surgery (SILAIS) using an SILS™ or EndoCone™ port. Prospective case series. Dogs (n = 7) and cat (n = 1). An SILS™ port using three 5-mm instrument cannulas or EndoCone™ port was used to perform an initial limited laparoscopic abdominal exploration. The stomach and descending duodenum were explored intracorporeally and the jejunum through orad descending colon was explored extracorporeally. All intestinal procedures (enterotomy, biopsy, resection, and anastomosis) were performed extracorporeally. Omentalization of affected bowel was accomplished either intracorporeally or extracorporeally. Short-term outcome was determined. SILAIS was completed successfully in all but 1 dog and all animals had a good short-term outcome. Most (n = 5) animals were discharged the day after surgery. SILAIS was performed in a median of 120 minutes (interquartile range; 82-148 minutes) and was associated with a moderate level of difficulty. No major complications occurred but conversion to celiotomy (n = 1) and enlargement of the incision (n = 3) was required because of inability to exteriorize the affected bowel. SILAIS using an SILS™ or EndoCone™ port in dogs and cats is feasible and appears effective in selected cases. Single portal laparoscopic-assisted intestinal surgery might be an effective method of minimizing morbidity in dogs and cats with uncomplicated intestinal disease. © Copyright 2013 by The American College of Veterinary Surgeons.

To describe the clinical features, diagnostic findings, treatment, and outcome of a dog with acute abdominal pain and hemoperitoneum secondary to a presumptive intraperitoneal (IP) snakebite. A 10-month-old castrated male mixed-breed dog was evaluated for suspected snake envenomation. The dog presented recumbent and tachycardic with signs of severe abdominal pain. Two cutaneous puncture wounds and hemoperitoneum were discovered during evaluation. Ultrasonographic examination revealed communication of the wounds with the peritoneal cavity. The dog was treated with supportive care, parenteral analgesia, packed red blood cell and fresh frozen plasma transfusions, crotalid antivenom, and placement of an IP catheter to provide local analgesia. The dog recovered fully and was discharged 5 days after initial presentation. To our knowledge, this is the first report of IP envenomation accompanied by hemorrhage treated with continuous IP analgesia in the veterinary literature. © Veterinary Emergency and Critical Care Society 2015.

Recent trials have questioned the benefit of early parenteral nutrition in adults. The effect of early parenteral nutrition on clinical outcomes in critically ill children is unclear. We conducted a multicenter, randomized, controlled trial involving 1440 critically ill children to investigate whether withholding parenteral nutrition for 1 week (i.e., providing late parenteral nutrition) in the pediatric intensive care unit (ICU) is clinically superior to providing early parenteral nutrition. Fluid loading was similar in the two groups. The two primary end points were new infection acquired during the ICU stay and the adjusted duration of ICU dependency, as assessed by the number of days in the ICU and as time to discharge alive from ICU. For the 723 patients receiving early parenteral nutrition, parenteral nutrition was initiated within 24 hours after ICU admission, whereas for the 717 patients receiving late parenteral nutrition, parenteral nutrition was not provided until the morning of the 8th day in the ICU. In both groups, enteral nutrition was attempted early and intravenous micronutrients were provided. Although mortality was similar in the two groups, the percentage of patients with a new infection was 10.7% in the group receiving late parenteral nutrition, as compared with 18.5% in the group receiving early parenteral nutrition (adjusted odds ratio, 0.48; 95% confidence interval [CI], 0.35 to 0.66). The mean (±SE) duration of ICU stay was 6.5±0.4 days in the group receiving late parenteral nutrition, as compared with 9.2±0.8 days in the group receiving early parenteral nutrition; there was also a higher likelihood of an earlier live discharge from the ICU at any time in the late-parenteral-nutrition group (adjusted hazard ratio, 1.23; 95% CI, 1.11 to 1.37). Late parenteral nutrition was associated with a shorter duration of mechanical ventilatory support than was early parenteral nutrition (P=0.001), as well as a smaller proportion of patients

Home parenteral nutrition has become routine for management of intestinal failure in patients. In Poland the main obstacle to widespread use of home parenteral nutrition is the lack of interest of commercial companies in delivering feedings and ancillaries to patients. Twenty-five home parenteral nutrition patients aged from 4 months to more than 13 years were reviewed. The mother or both parents were trained in home parenteral nutrition techniques for 4 to 6 weeks and compounded the nutrients themselves at home. The mean duration of home parenteral nutrition was 10,117 patient days. Hospital stays of patients receiving parenteral feedings were significantly shorter than the duration of administration of home parenteral nutrition (p rate of catheter occlusion decreased within the observation period, and in 1997 not one case of occlusion was observed. In 1997 only three catheters were removed during 7.8 patient years, and the overall incidence of catheter-related complications was 0.38 per patient year. The overall occurrence of septicemia was one case in 516 days and of catheter infection was one in 459 days. In 1997 a catheter was infected on average of once every 1419 days. There was significant improvement in the z score for weight during therapy. The average monthly cost of nutrients and ancillary items was approximately $1200 (4200 Polish zlotys [PLN]). These costs are 1.6 to 3 times lower than those recorded in other studies. Home parenteral nutrition in children with nutrients mixed by caregivers in the home setting is a safe and appropriate method of treatment that can be used in countries where home parenteral nutrition solutions are not manufactured or where commercial home parenteral nutrition is not economically feasible.

To describe in dogs, a technique for single port access gastropexy and ovariectomy (SPAGO) using a commercially available multitrocar port and to evaluate short-term outcome. Retrospective case series. Dogs (n = 18). A commercially available multitrocar port was inserted into the abdomen lateral to the rectus abdominis muscle and 2-5 cm caudal to the right rib. Dogs were tilted 45° in both left and right recumbency and bilateral ovariectomy performed using articulating graspers, a bipolar vessel sealing device and a 30° telescope. The laparoscopic assisted incisional gastropexy was performed after ovariectomy at the multitrocar port insertion site by grasping the antral portion of the stomach with a 10 mm DuVall forceps and suturing the seromuscular layer of the antral region of the stomach to the transversus abdominis muscle. Eighteen dogs (median weight, 34.5 kg; range, 14.7-59.2 kg) met the inclusion criteria. Median surgical time for SPAGO was 65 minutes (range, 50-225 minutes). Intra-operative complications included, incorrect multitrocar port placement location (n = 3) and mild hemorrhage from a splenic laceration (1) All dogs recovered from surgery and were discharged from the hospital. Single port access gastropexy and ovariectomy is a feasible procedure to provide prophylaxis against gastric dilation-volvulus and a simultaneous means of sterilization in female dogs. Careful and accurate initial multitrocar port insertion is necessary to have optimal operative viewing as well as to reduce the chances of inadvertent splenic laceration. © Copyright 2013 by The American College of Veterinary Surgeons.

Parenteral nutrition (PN) provision is complex, as it is a high-alert medication and prone to a variety of potential errors. With changes in clinical practice models and recent federal rulings, the number of PN prescribers may be increasing. Safe prescribing of this therapy requires that competency for prescribers from all disciplines be demonstrated using a standardized process. A standardized model for PN prescribing competency is proposed based on a competency framework, the American Society for Parenteral and Enteral Nutrition (A.S.P.E.N.)-published interdisciplinary core competencies, safe practice recommendations, and clinical guidelines. This framework will guide institutions and agencies in developing and maintaining competency for safe PN prescription by their staff. © 2015 American Society for Parenteral and Enteral Nutrition.

Dogs recognize dog and human emotions.

2016-01-01

The perception of emotional expressions allows animals to evaluate the social intentions and motivations of each other. This usually takes place within species; however, in the case of domestic dogs, it might be advantageous to recognize the emotions of humans as well as other dogs. In this sense, the combination of visual and auditory cues to categorize others' emotions facilitates the information processing and indicates high-level cognitive representations. Using a cross-modal preferential looking paradigm, we presented dogs with either human or dog faces with different emotional valences (happy/playful versus angry/aggressive) paired with a single vocalization from the same individual with either a positive or negative valence or Brownian noise. Dogs looked significantly longer at the face whose expression was congruent to the valence of vocalization, for both conspecifics and heterospecifics, an ability previously known only in humans. These results demonstrate that dogs can extract and integrate bimodal sensory emotional information, and discriminate between positive and negative emotions from both humans and dogs. © 2016 The Author(s).

In response to concerns raised about the quality of parenteral vancomycin products, the U.S. Food and Drug Administration (FDA) is investigating the product quality of all FDA-approved parenteral vancomycin products available in the United States. Product quality was evaluated independently at two FDA Office of Testing and Research (FDA-OTR) sites. In the next phase of the investigation, being done in collaboration with the National Institute of Allergy and Infectious Diseases, the in vivo activity of these products will be evaluated in an appropriate animal model. This paper summarizes results of the FDA investigation completed thus far. One site used a validated ultrahigh-pressure liquid chromatography method (OTR-UPLC), and the second site used the high-performance liquid chromatography (HPLC) method for related substances provided in the British Pharmacopeia (BP) monograph for vancomycin intravenous infusion. Similar results were obtained by the two FDA-OTR laboratories using two different analytical methods. The products tested had 90 to 95% vancomycin B (active component of vancomycin) by the BP-HPLC method and 89 to 94% vancomycin by OTR-UPLC methods. Total impurities were 5 to 10% by BP-HPLC and 6 to 11% by OTR-UPLC methods. No single impurity was >2.0%, and the CDP-1 level was ≤ 2.0% across all products. Some variability in impurity profiles of the various products was observed. No adverse product quality issues were identified with the six U.S. vancomycin parenteral products. The quality parameters of all parenteral vancomycin products tested surpassed the United States Pharmacopeia acceptance criteria.

Parenteral nutrition became a routine therapeutic option in malnourished patients, if conventional nutritional enteral support is not effective. Cachexia and malnutrition prolong the wound healing, contribute to immunosuppression, increase morbidity and the cost of treatment. Using of a malnutrition protocol as a screening tool is necessary to sort out malnourished patients. Parenteral nutrition is therefore an important part of the multimodal therapy and from the medical and the ethical point of view is a great mistake not to feed a patient. (author)

Parenteral nutrition is crucial for supply of nutrients in children who cannot tolerate a full enteral diet. In the United States, it is not standard of care to give iodine to children dependent on parenteral nutrition, hence iodine is not routinely included in the micronutrient package. Herein, we present a case of a boy with hypothyroidism secondary to iodine deficiency after prolonged exclusive use of parenteral nutrition. Our case highlights the importance of screening for iodine deficiency and administering timely iodine supplementation in these at-risk children to prevent iatrogenic hypothyroidism. © 2015 American Society for Parenteral and Enteral Nutrition.

Parenteral nutrition (PN) is a high-alert medication with a complex drug use process. Key steps in the process include the review of each PN prescription followed by the preparation of the formulation. The preparation step includes compounding the PN or activating a standardized commercially available PN product. The verification and review, as well as preparation of this complex therapy, require competency that may be determined by using a standardized process for pharmacists and for pharmacy technicians involved with PN. An American Society for Parenteral and Enteral Nutrition (ASPEN) standardized model for PN order review and PN preparation competencies is proposed based on a competency framework, the ASPEN-published interdisciplinary core competencies, safe practice recommendations, and clinical guidelines, and is intended for institutions and agencies to use with their staff. © 2016 American Society for Parenteral and Enteral Nutrition.

Timing of the initiation of parenteral nutrition in critically ill children.

2017-05-01

To review the current literature evaluating clinical outcomes of early and delayed parenteral nutrition initiation among critically ill children. Nutritional management remains an important aspect of care among the critically ill, with enteral nutrition generally preferred. However, inability to advance enteral feeds to caloric goals and contraindications to enteral nutrition often leads to reliance on parenteral nutrition. The timing of parenteral nutrition initiation is varied among critically ill children, and derives from an assessment of nutritional status, energy requirements, and physiologic differences between adults and children, including higher nutrient needs and lower body reserves. A recent randomized control study among critically ill children suggests improved clinical outcomes with avoiding initiation of parenteral nutrition on day 1 of admission to the pediatric ICU. Although there is no consensus on the optimal timing of parenteral nutrition initiation among critically ill children, recent literature does not support the immediate initiation of parenteral nutrition on pediatric ICU admission. A common theme in the reviewed literature highlights the importance of accurate assessment of nutritional status and energy expenditure in deciding when to initiate parenteral nutrition. As with all medical interventions, the initiation of parenteral nutrition should be considered in light of the known benefits of judiciously provided nutritional support with the known risks of artificial, parenteral feeding.

Background: Clinical practice guidelines recommend enteral over parenteral nutrition in critical illness and do not recommend early initiation. Few data are available on parenteral nutrition use or timing of initiation in the ICU or how this use may have changed over time. Methods: We used the Project IMPACT database to evaluate temporal trends in parenteral nutrition use (total and partial parenteral nutrition and lipid supplementation) and timing of initiation in adult ICU admissions from 2001 to 2008. We used χ2 tests and analysis of variance to examine characteristics of patients receiving parenteral nutrition and multilevel multivariate logistic regression models to assess parenteral nutrition use over time, in all patients and in specific subgroups. Results: Of 337,442 patients, 20,913 (6.2%) received parenteral nutrition. Adjusting for patient characteristics, the use of parenteral nutrition decreased modestly over time (adjusted probability, 7.2% in 2001-2002 vs 5.5% in 2007-2008, P nutrition use increased simultaneously (adjusted probability, 11.5% in 2001-2002 vs 15.3% in 2007-2008, P parenteral nutrition declined most rapidly in emergent surgical patients, patients with moderate illness severity, patients in the surgical ICU, and patients admitted to an academic facility (P ≤ .01 for all interactions with year). When used, parenteral nutrition was initiated a median of 2 days (interquartile range, 1-3), after ICU admission and > 90% of patients had parenteral nutrition initiated within 7 days; timing of initiation of parenteral nutrition did not change from 2001 to 2008. Conclusions: Use of parenteral nutrition in US ICUs declined from 2001 through 2008 in all patients and in all examined subgroups, with the majority of parenteral nutrition initiated within the first 7 days in ICU; enteral nutrition use coincidently increased over the same time period.

Visser, Lance C; Scansen, Brian A; Schober, Karsten E

2013-06-01

A coronary artery anomaly characterized by the presence of a single left coronary ostium with absence of the right coronary ostium and an anomalous prepulmonic right coronary artery course was observed in two dogs with concurrent congenital pulmonary valve stenosis. This unique coronary artery anatomy is similar to the previously described single right coronary ostium with anomalous prepulmonic left coronary artery, the so-called type R2A anomaly, in that an anomalous coronary artery encircles the pulmonary valve annulus. Both dogs of this report, a boxer and an English bulldog, were of breeds known to be at risk for the type R2A anomaly. As such, veterinarians should be aware that the echocardiographic presence of a left coronary ostium in a dog with pulmonary valve stenosis does not exclude the possibility of a prepulmonic coronary artery anomaly that may enhance the risk of complications during balloon pulmonary valvuloplasty. A descriptive naming convention for coronary artery anomalies in dogs is also presented, which may be preferable to the older coding classification scheme. Copyright © 2013 Elsevier B.V.

Full Text Available PURPOSE: To compare the effect of parenteral versus enteral nutritional support in severe acute pancreatitis, with respect to efficacy, safety, morbidity, mortality and length of hospitalization. METHODS: The study was comprised of 31 patients, divided into a parenteral group (n=16 and an enteral group (n=15, who met severity criteria for abdominal tomography (Balthazar classes C, D, and E. The patients were compared by demographics, disease etiology, antibiotic prophylaxis, use or not of somatostatin, nutritional support, complications and disease progression. RESULTS: There was no statistical difference in the average duration of nutritional support, somatostatin, or antibiotics in the two groups. Imipenem was the drug of choice for prophylaxis of pancreatic infections in both groups. More complications occurred in the parenteral group, although the difference was not statistically significant (p=0.10. Infectious complications, such as catheter sepsis and infections of the pancreatic tissue, were significantly more frequent in the parenteral group (p=0.006. There was no difference in average length of hospitalization in the two groups. There were three deaths in the parenteral group and none in the enteral group. CONCLUSION: Enteral nutritional support is associated with fewer septic complications compared to parenteral nutritional support.OBJETIVO: Comparar o efeito do suporte nutricional parenteral versus enteral, em pancreatite aguda grave, com relação à eficácia, à segurança, à morbi-mortalidade e ao tempo de internação.

Carmichael, L E; Joubert, J C; Pollock, R V

1981-10-01

A canine parvovirus (CPV) strain (C-780916) was found attenuated for pups at 80, but not after 51 serial passages in dog kidney cell (DKC) cultures. A variant viral population ('large plaque') emerged after prolonged cultivation in DKC cultures that may be associated with reduced native virulence. Dogs vaccinated with modified CPV developed high hemagglutination-inhibiting (HI) antibody titers within 4 days of incoluation and antibody persisted. Vaccinated animals shed small amounts of virus in the feces that spread to contact dogs. After five back-passages in dogs the modified strain was not pathogenic for pups and the plaque characteristics of the virus isolated from the feces were typical of the attenuated strain. The modified live CPV did not cause infection of the fetus when inoculated parenterally into pregnant bitches at various stages of gestation. It was not pathogenic for neonatal pups. These results suggest that a safe and effective live homologous (CPV) vaccine has been developed which should aid substantially in controlling CPV infection.

Home parenteral nutrition (HPN) is a high-cost, complex nutrition support therapy that requires the use of central venous catheters. Central line-associated bloodstream infections (CLABSIs) are among the most serious risks of this therapy. Sustain: American Society for Parenteral and Enteral Nutrition's National Patient Registry for Nutrition Care (Sustain registry) provides the most current and comprehensive data for studying CLABSI among a national cohort of HPN patients in the United States. This is the first Sustain registry report detailing longitudinal data on CLABSI among HPN patients. To describe CLABSI rates for HPN patients followed in the Sustain registry from 2011-2014. Descriptive, χ 2 , and t tests were used to analyze data from the Sustain registry. Of the 1,046 HPN patients from 29 sites across the United States, 112 (10.7%) experienced 194 CLABSI events during 223,493 days of HPN exposure, for an overall CLABSI rate of 0.87 episodes/1,000 parenteral nutrition-days. Although the majority of patients were female (59%), adult (87%), white (75%), and with private insurance or Medicare (69%), CLABSI episodes per 1,000 parenteral nutrition-days were higher for men (0.69 vs 0.38), children (1.17 vs 0.35), blacks (0.91 vs 0.41), and Medicaid recipients (1.0 vs 0.38 or 0.39). Patients with implanted ports or double-lumen catheters also had more CLABSIs than those with peripherally inserted or central catheters or single-lumen catheters. Staphylococci were the most commonly reported pathogens. These data support findings of smaller studies about CLABSI risk for children and by catheter type and identify new potential risk factors, including gender, race, and insurance type. Additional studies are needed to determine effective interventions that will reduce HPN-associated CLABSI. Copyright © 2016 Association for Professionals in Infection Control and Epidemiology, Inc.

Regional cerebral blood flow (rCBF) in eight dogs with congenital portosystemic shunt (PSS) and hepatic encephalopathy (HE) was compared with rCBF in eight healthy control dogs using single photon emission computed tomography (SPECT) with a 99m technetium-hexamethylpropylene amine oxime ( 99m Tc-HMPAO) tracer. SPECT scans were abnormal in all PSS dogs. Compared to the control group, rCBF in PSS dogs was significantly decreased in the temporal lobes and increased in the subcortical (thalamic and striatal) area. Brain perfusion imaging alterations observed in the dogs with PSS and HE are similar to those in human patients with HE. These findings suggest that dogs with HE and PSS have altered perfusion of mainly the subcortical and the temporal regions of the brain. Copyright © 2016 Elsevier Ltd. All rights reserved.

Preliminary application of a single-port access technique for laparoscopic ovariohysterectomy in dogs

Sánchez-Margallo, F. M.; Tapia-Araya, A.; Díaz-Güemes, I.

2015-01-01

Laparoscopic ovariohysterectomy using single-portal access was performed in nine selected owned dogs admitted for elective ovariohysterectomy and the surgical technique and outcomes were detailed. A multiport device (SILS Port, Covidien, USA) was placed at the umbilical area through a single 3 cm incision. Three cannulae were introduced in the multiport device through the access channels and laparoscopic ovariohysterectomy was performed using a 5-mm sealing device, a 5-mm articulating grasper and a 5-mm 30° laparoscope. The mean total operative time was 52.66±15.20 minutes and the mean skin incision during surgery was 3.09±0.20 cm. Of the nine cases examined, in the one with an ovarian tumour, the technique was converted to multiport laparoscopy introducing an additional 5-mm trocar. No surgical complications were encountered and intraoperative blood loss was minimum in all animals. Clashing of the instruments and reduced triangulation were the main limitations of this technique. The combination of articulated and straight instruments facilitated triangulation towards the surgical field and dissection capability. One month after surgery a complete wound healing was observed in all animals. The present data showed that ovariohysterectomy performed with a single-port access is technically feasible in dogs. The unique abdominal incision minimises the abdominal trauma with good cosmetic results. PMID:26568831

Treatment of canine epilepsy is problematic. Few antiepileptic drugs have proven efficacy in dogs and undesirable adverse effects and pharmacoresistance are not uncommon. Consequently, the need for investigation of alternative treatment options is ongoing. The objective of this study was to investigate the efficacy and tolerability of levetiracetam as mono-therapy in dogs with idiopathic epilepsy. The study used a prospective single-blinded parallel group design. Twelve client-owned dogs were included and were randomised to treatment with levetiracetam (30 mg/kg/day or 60 mg/kg/day divided into three daily dosages) or phenobarbital (4 mg/kg/day divided twice daily). Control visits were at days 30, 60 and then every 3 months for up to 1 year. Two or more seizures within 3 months led to an increase in drug dosage (levetiracetam: 10 mg/kg/day, phenobarbital: 1 mg/kg/day). Five of six levetiracetam treated dogs and one of six phenobarbital treated dogs withdrew from the study within 2-5 months due to insufficient seizure control. In the levetiracetam treated dogs there was no significant difference in the monthly number of seizures before and after treatment, whereas in the phenobarbital treated dogs there were significantly (P = 0.013) fewer seizures after treatment. Five phenobarbital treated dogs were classified as true responders (≥50% reduction in seizures/month) whereas none of the levetiracetam treated dogs fulfilled this criterion. Adverse effects were reported in both groups but were more frequent in the phenobarbital group. In this study levetiracetam was well tolerated but was not effective at the given doses as mono-therapy in dogs with idiopathic epilepsy. Copyright © 2015 Elsevier Ltd. All rights reserved.

Phytosterols, Lipid Administration, and Liver Disease During Parenteral Nutrition.

Science.gov (United States)

Zaloga, Gary P

2015-09-01

Phytosterols are plant-derived sterols that are structurally and functionally analogous to cholesterol in vertebrate animals. Phytosterols are found in many foods and are part of the normal human diet. However, absorption of phytosterols from the diet is minimal. Most lipid emulsions used for parenteral nutrition are based on vegetable oils. As a result, phytosterol administration occurs during intravenous administration of lipid. Levels of phytosterols in the blood and tissues may reach high levels during parenteral lipid administration and may be toxic to cells. Phytosterols are not fully metabolized by the human body and must be excreted through the hepatobiliary system. Accumulating scientific evidence suggests that administration of high doses of intravenous lipids that are high in phytosterols contributes to the development of parenteral nutrition-associated liver disease. In this review, mechanisms by which lipids and phytosterols may cause cholestasis are discussed. Human studies of the association of phytosterols with liver disease are reviewed. In addition, clinical studies of lipid/phytosterol reduction for reversing and/or preventing parenteral nutrition associated liver disease are discussed. © 2015 American Society for Parenteral and Enteral Nutrition.

Pharmaceutical Point of View on Parenteral Nutrition

2013-01-01

Full Text Available Parenteral nutrition—a form of administering nutrients, electrolytes, trace elements, vitamins, and water—is a widely used mode of therapy applied in many diseases, in patients of different ages both at home and in hospital. The success of nutritional therapy depends chiefly on proper determination of the patient’s energetic and electrolytic needs as well as preparation and administration of a safe nutritional mixture. As a parenterally administered drug, it is expected to be microbiologically and physicochemically stable, with all of the components compatible with each other. It is very difficult to obtain a stable nutritional mixture due to the fact that it is a complex, two-phase drug. Also, the risk of incompatibility between mixture components and packaging should be taken into consideration and possibly eliminated. Since parenteral nutrition is a part of therapy, simultaneous use of drugs may cause pharmacokinetic and pharmacodynamic interactions as well as those with the pharmaceutical phase. The aim of this paper is to discuss such aspects of parenteral nutrition as mixture stability, methodology, and methods for determining the stability of nutritional mixtures and drugs added to them.

Aggressive parenteral nutrition is the standard of care among very-low-birth weight preterm infants. However, in recent studies, its impact on short-term outcomes, has been evaluated. The objective was to compare the prevalence of hypercalcemia and hypophosphatemia among preterm infants receiving aggressive or standard parenteral nutrition. Observational, retrospective study comparing a group of preterm infants weighing less than 1250 grams who received aggressive parenteral nutrition with a historical control group. The prevalence of hypercalcemia was estimated and its association with aggressive parenteral nutrition was searched adjusting by confounders. The mean phosphate level was estimated for the control group by linear regression and was compared to the value in the other group. Forty patients per group were included. The prevalence of hypercalcemia was higher in the group who received aggressive parenteral nutrition (87.5% versus 35%, p= 0.001). Aggressive parenteral nutrition was associated with hypercalcemia when adjusting by birth weight, intrauterine growth restriction, amino acid, and calorie intake (adjusted odds ratio: 21.8, 95% confidence interval [CI]: 3.7-128). The mean calcium level was different between both groups (p= 0.002). Infants who received aggressive parenteral nutrition had more sepsis without reaching statistical significance and the mean phosphate level was lower than that estimated for the control group (p= 0.04). The prevalence of hypophosphatemia in this group was 90% (95% CI: 76-97%). Our data show an association between hypercalcemia/hypophosphatemia and aggressive parenteral nutrition. It is recommended to frequently monitor calcium and phosphate levels since they might be associated with adverse clinical outcomes. Sociedad Argentina de Pediatría.

Parenteral nutrition is now a standard part of supportive treatment in pediatric departments. We describe four cases in which parenteral nutrition was extremely difficult due to coincidence with inborn errors of metabolism. The first two cases was fatty acid beta-oxidation disorders associated with necrotizing enterocolitis and congenital heart disease. Thus, limitations of intravenous lipid intake made it difficult to maintain a good nutritional status. The third case was phenylketonuria associated with a facial region tumour (rhabdomyosarcoma), in which parenteral nutrition was complicated because of a high phenylalanine content in the amino acid formulas for parenteral nutrition. The fourth patient was a child with late-diagnosed tyrosinemia type 1, complicated with encephalopathy - during intensive care treatment the patient needed nutritional support, including parenteral nutrition - we observed amino acid formula problems similar to those in the phenylketonuria patient. Parenteral nutrition in children with inborn errors of metabolism is a rare, but very important therapeutic problem. Total parenteral nutrition formulas are not prepared for this group of diseases.

To compare procedure times and major and minor complication rates associated with single-chamber versus dual-chamber pacemaker implantation and with 1-lead, 2-lead, and 3-lead pacemaker implantation in dogs with clinical signs of bradyarrhythmia. Retrospective case series. 54 dogs that underwent pacemaker implantation because of clinical signs of bradyarrhythmia. Medical records of dogs that received pacemakers between July 2004 and December 2009 were reviewed for information regarding signalment, diagnosis, pacemaker implantation, pacemaker type, complications, and survival time. Analyses were performed to determine significant differences in anesthesia time, procedure time, and outcome for dogs on the basis of pacing mode and number of pacing leads. 28 of 54 (51.9%) dogs received single-chamber pacemakers and 26 (48.1%) received dual-chamber pacemakers. Mean ± SD procedural time was significantly longer for patients with dual-chamber pacemakers (133.5 ± 51.3 minutes) than for patients with single-chamber pacemakers (94.9 ± 37.0 minutes), and procedure time increased significantly as the number of leads increased (1 lead, 102.3 ± 51.1 minutes; 2 leads, 114.9 ± 24.8 minutes; 3 leads, 158.2 ± 8.5 minutes). Rates of major and minor complications were not significantly different between dogs that received single-chamber pacemakers and those that received dual-chamber pacemakers or among dogs grouped on the basis of the number of pacing leads placed. Although dual-chamber pacemaker implantation did result in increased procedural and anesthesia times, compared with single-chamber pacemaker implantation, this did not result in a higher complication rate.

Full Text Available Objective(s: Production of effective tuberculosis (TB vaccine is necessity. However, the development of new subunit vaccines is faced with concerns about their weak immunogenicity. To overcome such problems, polymers-based vaccine delivery systems have been proposed to be used via various routes. The purpose of this study was to determine the potential of polymeric particles as future vaccine delivery systems/adjuvants for parenteral and non-parenteral immunization against TB. Materials and Methods: PubMed, Scopus, Science-Direct, and the ISI web of knowledge databases were searched for related keywords. A total of 420 articles, written up to June 25, 2016, were collected on the potential of polymeric particles as TB vaccine delivery systems after parenteral and non-parenteral immunization. Thirty-one relevant articles were selected by applying inclusion and exclusion criteria. Results: It was shown that the immunogenicity of TB vaccines had been improved by using biodegradable and non-biodegradable synthetic polymers as well as natural polymers and they are better able to enhance the humoral and cellular immune responses, compared to TB vaccines alone. The present study revealed that various polymeric particles, after M. tuberculosis challenge in animal models, provide long-lasting protection against TB. PLGA (poly (lactide-co-glycolide and chitosan polymers were widely used as TB vaccine delivery systems/adjuvants. Conclusion: It seems that PLGA and chitosan polymers are well-suited particles for the parenteral and non-parenteral administration of TB vaccines, respectively. Non-biodegradable synthetic polymers in comparison with biodegradable synthetic and natural polymers have been used less frequently. Therefore, further study on this category of polymers is required.

Full Text Available Objectives: The aim was to evaluate the effect of parenteral testosterone on penile length, preputial hood, vascularity of dartos pedicle in patients with hypospadias. Materials and Methods: A total of 42 patients with hypospadias were included in this study. Injection aquaviron (oily solution each ml containing testosterone propionate 25 mg was given deep intramuscularly in three doses with an interval of 3 weeks before reconstructive surgery at the dose of 2 mg/kg body weight. Preoperatively penile length, transverse preputial width and diameter at the base of the penis were measured. Basal testosterone levels were obtained before the institution of therapy and on the day of operation. Results: Following parenteral testosterone administration, the mean increase in penile length, transverse preputial width and diameter at the base of penis was 1.01 ± 0.25 cm (P < 0.001, 1.250 ± 0.52 cm and 0.61 ± 0.35 cm, respectively, (P < 0.001. Serum testosterone level after injection was well within normal range for that age. Conclusion: Parenteral testosterone increased phallus size, diameter and prepuce hypertrophy without any adverse effects. However, due to lack of a control group we cannot make any inferences. Controlled studies are required to establish the benefits of parenteral testosterone.

Full Text Available Arlet G Kurkchubasche,1 Thomas J Herron,2 Marion F Winkler31Department of Surgery and Pediatrics, 2Department of Surgery, Alpert Medical School of Brown University, 3Department of Surgery/Nutritional Support Service, Rhode Island Hospital, Providence, RI, USAAbstract: Intestinal failure is a consequence of extensive surgical resection resulting in anatomic loss and/or functional impairment in motility or absorptive capacity. The condition is clinically characterized by the inability to maintain fluid, energy, protein, electrolyte, or micronutrient balance when on a conventionally accepted, normal diet. Parenteral nutrition (PN is the cornerstone of management until intestinal adaptation returns the patient to a PN-independent state. Intestinal length, residual anatomic segments and motility determine the need for and duration of parenteral support. The goals of therapy are to provide sufficient nutrients to enable normal growth and development in children, and support a healthy functional status in adults. This review addresses indications for PN, the formulation of the PN solution, patient monitoring, and considerations for prevention of PN-associated complications. With the ultimate goal of achieving enteral autonomy, the important role of diet, pharmacologic interventions, and surgery is discussed.Keywords: intestinal failure, short-bowel syndrome, parenteral nutrition, home nutrition support, intestinal rehabilitation

Parenteral Nutrition with hypertonic glucose is frequently given to diabetic patients. Large amounts of insulin can be required. The purpose of this investigation was to develop a totally parenterally nourished diabetic rat model. 200 g Female Sprague Dawley rats were made diabetic by i.v. injection of streptozotocin (50 mg/kg). Rats were then allowed to recover for at least 1 week before undergoing surgical insertion of a central venous catheter for parenteral feeding. TPN was begun 3 days after surgery. Prior to this they were allowed unlimited access to food and water. Control (non-streptozotocin treated) rats were run at the same time. Protein turnover was investigated by using 15 N glycine. Preliminary results: diabetic rats given mostly fat as a calorie source survived well in the absence of exogenous insulin whereas those that were given glucose only as their non-protein calorie source showed poor survival even with exogenous insulin. N balance and protein turnover in the lipid treated diabetic rats were comparable to the non-diabetic control rats

Full Text Available Objectives : This study was performed to analyse single dose toxicity of Sweet Bee Venom(Sweet BV extracted from the bee venom in Beagle dogs. Methods : All experiments were conducted under the regulations of Good Laboratory Practice (GLP at Biotoxtech Company, a non-clinical study authorized institution. Male and female Beagle dogs of 5-6 months old were chosen for the pilot study of single dose toxicity of Sweet BV which was administered at the level of 9.0 ㎎/㎏ body weight which is 1300 times higher than the clinical application dosage as the high dosage, followed by 3.0 and 1.0 ㎎/㎏ as midium and low dosage, respectively. Equal amount of excipient(normal saline to the Sweet BV experiment groups was administered as the control group. Results : 1. No mortality was witnessed in all of the experiment groups. 2. Hyperemia and movement disorder were observed around the area of administration in all the experiment groups, and higher occurrence in the higher dosage treatment. 3. For weight measurement, Neither male nor female groups showed significant changes. 4. To verify abnormalities of organs and tissues, thigh muscle which treated with Sweet BV, brain, liver, lung, kidney, and spinal cords were removed and histologocal observation using H-E staining was conducted. In the histologocal observation of thigh muscle, cell infiltration, inflammation, degeneration, necrosis of muscle fiber, and fibrosis were found in both thigh tissue. And the changes depend on the dose of Sweet BV. But the other organs did not showed in any abnormality. 5. The maximum dose of Sweet BV in Beagle dogs were over 9 ㎎/㎏ in this study. Conclusions : The above findings of this study suggest that Sweet BV is a relatively safe treatment medium. Further studies on the toxicity of Sweet BV should be conducted to yield more concrete evidences.

OBJECTIVE To investigate metabolite concentrations of the brains of dogs with intracranial neoplasia or noninfectious meningoencephalitis by use of short echo time, single voxel proton magnetic resonance spectroscopy ((1)H MRS) at 3.0 T. ANIMALS 29 dogs with intracranial lesions (14 with neoplasia [3 oligodendromas, 3 glioblastomas multiformes, 3 astrocytomas, 2 lymphomas, and 3 meningiomas] and 15 is with noninfectious meningoencephalitis) and 10 healthy control dogs. PROCEDURES Short echo time, single voxel (1)H-MRS at 3.0 T was performed on neoplastic and noninfectious inflammatory intracranial lesions identified with conventional MRI. Metabolites of interest included N-acetyl aspartate (NAA), total choline, creatine, myoinositol, the glutamine-glutamate complex (Glx), glutathione, taurine, lactate, and lipids. Data were analyzed with postprocessing fitting algorithm software. Metabolite concentrations relative to brain water content were calculated and compared with results for the healthy control dogs, which had been previously evaluated with the same (1)H MRS technique. RESULTS NAA, creatine, and Glx concentrations were reduced in the brains of dogs with neoplasia and noninfectious meningoencephalitis, whereas choline concentration was increased. Concentrations of these metabolites differed significantly between dogs with neoplasia and dogs with noninfectious meningoencephalitis. Concentrations of NAA, creatine, and Glx were significantly lower in dogs with neoplasia, whereas the concentration of choline was significantly higher in dogs with neoplasia. Lipids were predominantly found in dogs with high-grade intra-axial neoplasia, meningioma, and necrotizing meningoencephalitis. A high concentration of taurine was found in 10 of 15 dogs with noninfectious meningoencephalitis. CONCLUSIONS AND CLINICAL RELEVANCE (1)H MRS provided additional metabolic information about intracranial neoplasia and noninfectious meningoencephalitis in dogs.

Parenteral nutrition in the ICU setting: need for a shift in utilization.

The difficulties to feed the patients adequately with enteral nutrition alone have drawn the attention of the clinicians toward the use of parenteral nutrition, although recommendations by the recent guidelines are conflicting. This review focuses on the intrinsic role of parenteral nutrition, its new indication, and modalities of use for the critically ill patients. A recent trial demonstrated that selecting either parenteral nutrition or enteral nutrition for early nutrition has no impact on clinical outcomes. However, it must be acknowledged that the risk of relative overfeeding is greater when using parenteral nutrition and the risk of underfeeding is greater when using enteral nutrition because of gastrointestinal intolerance. Both overfeeding and underfeeding in the critically ill patients are associated with deleterious outcomes. Thus, early and adequate feeding according to the specific energy needs can be recommended as the optimal feeding strategy. Parenteral nutrition can be used to substitute or supplement enteral nutrition, if adequately prescribed. Testing for enteral nutrition tolerance during 2-3 days after ICU admission provides the perfect timing to start parenteral nutrition, if needed. In case of absolute contraindication for enteral nutrition, consider starting parenteral nutrition carefully to avoid overfeeding.

Parenteral nutrition may be considered when oral intake and/or enteral nutrition are not sufficient to maintain nutritional status and the patient is likely to die sooner from starvation than from the cancer. A detailed assessment should be made prior to the decision about whether parenteral nutrition should be started. A follow up plan should be documented with objective and patient centred treatment goals as well as specific time points for evaluation. Copyright © 2015 Elsevier Inc. All rights reserved.

for hypocalcaemia and discharged from hospital. Acute management included parenteral calcium gluconate (10 dogs) and intravenous anticonvulsants (five dogs). Chronic therapy included oral vitamin D analogues and calcium supplementation. Treatment complications occurred in two dogs and included acute renal failure (one dog) and iatrogenic tissue necrosis following subcutaneous calcium administration (one dog). The mean follow-up period was 14.5 months (median 13 months, range 0 to 39 months). Twelve dogs were alive at the last follow up and two dogs were euthanased for unrelated reasons. The type of vitamin D analogue used was not associated with outcome. Primary hypoparathyroidism was an uncommon diagnosis in dogs. Saint Bernards, cross bred dogs, German Shepherd dogs and Terrier breeds were most commonly affected. Neurological signs were the most common presenting clinical signs, although alimentary signs may have been more common than previously reported. Dogs with primary hypoparathyroidism appeared to have a good prognosis following initiation of calcium supplementation and vitamin D therapy. Complications of treatment were uncommon and could be minimised with regular monitoring.

Two single-site, laboratory, negatively controlled, masked, randomised dose confirmation studies were performed: one in dogs, the other in cats. After a period of acclimatisation, both the dogs and cats were orally infected with Echinococcus multilocularis protoscoleces. In the dog study, 10 dogs received a single dose of Milpro® tablets at a minimum dose of 0.5 mg/kg milbemycin oxime and 5 mg/kg praziquantel 18 days post-infection and 10 dogs received no treatment. In the cat study, 10 cats received a single dose of Milpro® tablets at a minimum dose of 2 mg/kg milbemycin oxime and 5 mg/kg praziquantel 7 days post-infection, 10 cats received a single dose of the treatment 18 days post-infection and 10 cats remained untreated. In both studies, intestinal worm counts were performed 23 days post-infection at necropsy. No worms were retrieved from any of the 30 treated animals. Nine of 10 control dogs had multiple worms (geometric mean 91, arithmetic mean 304) and all 10 control cats had multiple worms (geometric mean 216, arithmetic mean 481).

A vaccine based upon a recombinant plant virus (CPMV-PARVO1), displaying a peptide derived from the VP2 capsid protein of canine parvovirus (CPV), has previously been described. To date, studies with the vaccine have utilized viable plant chimaeric particles (CVPs). In this study, CPMV-PARVO1 was inactivated by UV treatment to remove the possibility of replication of the recombinant plant virus in a plant host after manufacture of the vaccine. We show that the inactivated CVP is able to protect dogs from a lethal challenge with CPV following parenteral immunization with the vaccine. Dogs immunized with the inactivated CPMV-PARVO1 in adjuvant displayed no clinical signs of disease and shedding of CPV in faeces was limited following CPV challenge. All immunized dogs elicited high titres of peptide-specific antibody, which neutralized CPV in vitro. Levels of protection, virus shedding and VP2-specific antibody were comparable to those seen in dogs immunized with the same VP2- peptide coupled to keyhole limpet hemocyanin (KLH). Since plant virus-derived vaccines have the potential for cost-effective manufacture and are not known to replicate in mammalian cells, they represent a viable alternative to current replicating vaccine vectors for development of both human and veterinary vaccines.

Tissue plasminogen activator (t-PA) and single chain urokinase-plasminogen activator (scu-PA) are relatively "fibrin-specific" thrombolytic drugs with short plasma half lives of 6-8 minutes. Most treatment regimens with these agents utilize a bolus injection followed by continuous drug infusion, usually combined with anticoagulant therapy. The purpose of this study was to establish the dose-response characteristics for scu-PA and t-PA, when given as a single intravenous bolus injection, in a dog model of arterial thrombosis. Eight groups of 6 dogs each were given one of the following doses of scu-PA (mg/kg): 0.20, 0.50, 1.00, 2.00; or t-PA: 0.05, 0.10, 0.20; or an equivalent amount of saline (control group). All doses were given as a single bolus injection 60 minutes after formation of a totally occlusive femoral artery thrombus. Thrombolysis was measured by monitoring the continuous decrement of 125I activity from a radiolabelled thrombus. Ninety minutes after drug injection, all scu-PA treated dogs showed greater thrombolysis (30%, 45%, 56%, and 67%, respectively) than the control group (15%, p less than 0.01). The 0.10 and 0.20 mg/kg t-PA treated dogs showed greater thrombolysis (35% and 49%, respectively) than the control group (15%, p less than 0.01). Both scu-PA and t-PA caused a partial and dose-dependent decrease in alpha 2-antiplasmin activity but scu-PA caused a greater depletion (72% vs. 18%, respectively, p less than 0.05) at 60 minutes after the highest dose of drug administration. Both drugs showed a longer than expected thrombolytic effect based upon the known half lives. Neither drug caused significant changes in the prothrombin time, activated partial thromboplastin time, thrombin time, hematocrit, platelet count, or fibrin degradation product concentration. Single bolus injections of scu-PA and t-PA produce safe and effective thrombolysis in this dog model of arterial thrombosis.

Objective: To study the clinical significance of changes of serum levels of TBA, CG, HA in neonate with parenteral nutrition. Methods: Serum total bile acid (TBA, with biochemistry) and CG, HA (with RIA) contents were measured in 52 neonates (full-term 32, preterm 20) with parenteral nutrition and 28 neonates (full-term 16, preterm 12) without parenteral nutrition (as controls). Results: Before parenteral nutrition,the serum TBA, CG and HA levels in full-term neonates were not significantly different from those in the controls (P>0.05). After parenteral nutrition,serum levels were significantly higher than those before parenteral nutrition (P<0.01). The levels in pre-term neonates were significantly higher after parenteral nutrition than those in full-term neonates (P<0.05). Conclusion: Long term parenteral nutrition might be harmful to hepatic and gall bladder function in neonates especially in premature ones. (authors)

Intestinal failure is associated frequently with liver injury, which persists after weaning off parenteral nutrition. We compared features of liver remodeling in intestinal failure during and after weaning off parenteral nutrition. Liver biopsies and serum samples were obtained from 25 intestinal failure patients at a median age of 9.7 years (interquartile range: 4.6-18) and from age-matched control patients. Seven patients had been receiving parenteral nutrition for 53 months (22-160), and 18 patients had been weaned off parenteral nutrition 6.3 years (2.4-17) earlier, after having received parenteral nutrition for 10 months (3.3-34). Expression of alpha-smooth muscle actin, collagen 1, proinflammatory cytokines, growth factors, and matrix metalloproteinases (MMPs) was measured. Significant increases in immunohistochemical expression of alpha-smooth muscle actin and collagen 1 were observed predominantly in portal areas and were similar to increases seen in patients currently receiving parenteral nutrition and in patients weaned off parenteral nutrition. Gene and protein expressions of alpha-smooth muscle actin and collagen were interrelated. Gene expression of ACTA2, encoding alpha-smooth muscle actin, was increased only in patients who were receiving parenteral nutrition currently. Comparable upregulation of interleukin-1 (α and ß), epidermal growth factor, integrin-ß6, and MMP9 gene expression was observed in both patient groups, irrespective of whether they were receiving parenteral nutrition currently. Liver expression and serum levels of TIMP1 and MMP7 were increased only in the patients on parenteral nutrition currently but were not increased after weaning off parenteral nutrition. Intestinal failure is characterized by abnormal activation of hepatic myofibroblast and accumulation of collagen both during and after weaning off parenteral nutrition. Persistent transcriptional upregulation of proinflammatory and fibrogenic cytokines after weaning off

Full Text Available Objectives: Parenteral nutrition-associated cholestasis (PNAC is one of the most challenging complications of prolonged parenteral nutrition (PN in neonates. There is a lack of research investigating its incidence in newborn infants in Oman and the Arab region. Therefore, this study aimed to assess the incidence of PNAC and its risk factors in Omani neonates. Methods: This retrospective study took place between January and April 2014. All neonates who received PN for ≥14 days during a four-year period (June 2009 to May 2013 at the neonatal intensive care unit (NICU in Sultan Qaboos University Hospital, Muscat, Oman, were enrolled. Results: A total of 1,857 neonates were admitted to the NICU over the study period and 135 neonates (7.3% received PN for ≥14 days. Determining the incidence of PNAC was only possible in 97 neonates; of these, 38 (39% had PNAC. The main risk factors associated with PNAC were duration of PN, duration of enteral starvation, gastrointestinal surgeries, blood transfusions and sepsis. Neonates with PNAC had a slightly higher incidence of necrotising enterocolitis in comparison to those without PNAC. Conclusion: This study found a PNAC incidence of 39% in Omani neonates. There were several significant risk factors for PNAC in Omani neonates; however, after logistic regression analysis, only total PN duration remained statistically significant. Preventive strategies should be implemented in NICUs so as to avoid future chronic liver disease in this population.

Limited or delayed availability of parenteral nutrition (PN) solutions, as well as difficulties in ordering are often identified as reasons for non-compliance with international guidelines in newborns. This study aims at assessing the modality of use and safety of premixed standardized PN solutions in a nationwide prospective cohort of newborns treated in clinical practice. Two premixed fixed formulations with respective osmolarity of 715 and 790 mOsm/L specifically designed for neonates were made available throughout the country for clinical use from birth onwards. Descriptive data and modality of use were prospectively collected in a case report form, whereas all related and unrelated adverse events were recorded on a separate adverse event form. A total of 14,167 infants were prospectively included and 16,640 parenteral nutrition periods were analyzed. Mean age was 33 weeks of gestation, and mean weight was 2086 g. The majority of infants (81%) started the parenteral nutrition the first day of life or the day after. The route of parenteral nutrition delivery was peripheral in 47% of the parenteral nutrition periods. During the whole study, a total of 72 adverse events occurring in 68 infants were reported. Of these adverse events, 59 (0.37% of the nutrition periods), among which 19 serious adverse events, were reported as related to the parenteral nutrition solutions. The events related to parenteral nutrition solutions were general disorders and administration site conditions (n = 42 including 9 cases of cutaneous necrosis), and nutrition and metabolism disorders (n = 17). There was no case of thrombophlebitis. Six of the 19 serious events related to the parenteral nutrition solutions (32%) were due to the misuse of the infusion bag. These data support the concept that ready-to-use parenteral nutrition formulations can safely provide parenteral nutrition from birth onwards. They further support that parenteral solutions with an osmolarity up to 800�

To compare the effectiveness of single dose activated charcoal, single dose activated charcoal with sorbitol, and multidose activated charcoal in reducing plasma carprofen concentrations following experimental overdose in dogs. Randomized, four period cross-over study. University research setting. Eight healthy Beagles. A 120 mg/kg of carprofen was administered orally to each dog followed by either (i) a single 2 g/kg activated charcoal administration 1 hour following carprofen ingestion (AC); (ii) 2 g/kg activated charcoal with 3.84 g/kg sorbitol 1 hour following carprofen ingestion (ACS); (iii) 2 g/kg activated charcoal 1 hour after carprofen ingestion and repeated every 6 hours for a total of 4 doses (MD); (iv) no treatment (control). Plasma carprofen concentrations were obtained over a 36-hour period following carprofen ingestion for each protocol. Pharmacokinetic modeling was performed and time versus concentration, area under the curve, maximum plasma concentration, time to maximum concentration, and elimination half-life were calculated and compared among the groups using ANOVA followed by Tukey's multiple comparisons test. Activated charcoal, activated charcoal with sorbitol (ACS), and multiple-dose activated charcoal (MD) significantly reduced the area under the curve compared to the control group. AC and MD significantly reduced the maximum concentration when compared to the control group. MD significantly reduced elimination half-life when compared to ACS and the control group. There were no other significant differences among the treatment groups. Activated charcoal and ACS are as effective as MD in reducing serum carprofen concentrations following experimental overdose in dogs. Prospective studies are warranted to evaluate the effectiveness of AC, ACS, and MD in the clinical setting. © Veterinary Emergency and Critical Care Society 2015.

The present study evaluated the microfilaricidal efficacy of a single application of the spot-on containing imidacloprid 10%/moxidectin 2.5% (Advocate(®), Bayer Animal Health) in dogs naturally infected either by Dirofilaria immitis or Dirofilaria repens. Dogs living in north-eastern and central-southern Italy, endemic for D. immitis and D. repens respectively, were randomly screened. Sixteen animals, eight infected with D. immitis and eight with D. repens, and fulfilling inclusion criteria were enrolled. Dogs infected with D. immitis received an adulticide treatment prior to the study and Advocate(®) 3 weeks after. The animals were divided in blocks of two (1:1, T1:T2) animals each, where Day 0 (D0) had an interval of 15days to compare T2 vs. T1 dogs during the first fortnight of examination (i.e. T2 dogs acted as control animals at each examination). At baseline (Days -15 and 0 for T2 and T1 dogs, respectively) the animals had a range of microfilaraemia of 180-99.700mff/ml (D. immitis) and 60-750 mff/ml (D. repens). All animals received a topical administration of Advocate(®) at D0 and were examined for microfilariae with microscopic and molecular tests at D15, D30, D60 and D90. All animals scored negative for mff at the first control post-treatment and throughout the study, with the exception of two D. immitis- infected animals that had a 2 mff/ml count at D15, and then become negative from Day 30 onwards. No adverse events were observed. The present study demonstrates the safety and the high microfilaricidal efficacy (99.97% and 100% for D. immitis and D. repens, respectively) of a single dose of moxidectin contained in Advocate(®) in naturally infected dogs.

Iodine is essential for thyroid hormone synthesis, and iodine deficiency may result in thyroid disorders including goiter and hypothyroidism. Patients on long-term enteral nutrition (EN) or parenteral nutrition (PN) may be at risk for micronutrient deficiencies. The recommended daily allowance for iodine intake is 150 μg for nonpregnant adults. However, there is no current consensus among scientific societies regarding the quantity of iodine to be added in adult EN and PN formulations. The objective of this study was to determine the iodine content of U.S. adult enteral and parenteral nutrition solutions. This study also aimed to determine whether adult patients in the United States who are receiving long-term artificial nutrition may be at risk for iodine deficiency. Ten enteral nutrition solutions and 4 parenteral nutrition solutions were evaluated. The iodine contents of these solutions were measured spectrophotometrically and compared to the labeled contents. Measured and labeled EN iodine contents were similar (range 131-176 μg/L and 106-160 μg/L, respectively). In contrast, PN formulas were found to contain small, unlabeled amounts of iodine, averaging 27 μg/L. Typical fluid requirements are 30 to 40 mL/kg/day for adults receiving either total EN (TEN) or total PN (TPN). Adults on long-term TEN likely consume enough servings to meet their daily iodine requirements. However, patients on long-term TPN would require on average 5.6 L PN/day to meet the recommended daily allowance of iodine. This volume of PN is far in excess of typical consumption. Thus, U.S. patients requiring long-term TPN may be at risk for iodine deficiency. EN = enteral nutrition; PN = parenteral nutrition; TEN = total enteral nutrition; TPN = total parenteral nutrition; UIC = urinary iodine concentration.

Reconciling divergent results of the latest parenteral nutrition studies in the ICU.

Recent studies on the optimal modalities to feed patients during the ICU stay show divergent results. The level and the timing of energy provision is a critical issue, associated with the clinical outcome. These results questioned the clinical relevance of the recent guidelines issued by American, Canadian and European academic societies. Four recent prospective randomized studies enrolled critically ill patients who received various nutritional regimens and tested the effect of nutritional support on outcome. The Tight Calorie balance Control Study (TICACOS) targeted on calorie administration according to measured energy expenditure and found increased ICU morbidity but improved hospital mortality. The large EpaNIC study compared 'early' with 'late' (parenteral nutrition) nutrition, mostly in patients after cardiac surgery, and found an increased morbidity associated with early parenteral nutrition. The supplemental parenteral nutrition (SPN) study randomized the patients after 3 days and targeted the calories administered by parenteral nutrition as a complement to unsuccessful enteral nutrition using indirect calorimetry. The SPN resulted in less nosocomial infections and shorter duration of mechanical ventilation. Finally, a recent Australian study enrolled patients unable to be early fed enterally to receive, or not, parenteral nutrition targeted at 1500 kcal. No complications were noted in the parenteral nutrition group. Lessons from all these studies are summarized and should help in designing better studies and guidelines. The critical analysis of recent prospective studies comparing various levels of calorie administration, enteral versus parenteral nutrition and enteral versus SPN confirms the recommendations to avoid underfeeding and overfeeding. Parenteral nutrition, required if enteral feeding is failing, and if adjusted up to a measured optimal level, may improve outcome.

To describe indications for, and outcomes after, pneumonectomy in dogs and cats, including assessment of immediate postoperative respiratory function in comparison to dogs undergoing single lung lobectomy. Retrospective case series. Dogs (n=16) and cats (n=7) with naturally occurring pulmonary disease. Medical records (1990-2014) of dogs and cats undergoing right or left pneumonectomy were reviewed. Data retrieved included signalment, history, preoperative diagnostics, operative descriptions, postoperative data including respiratory function, and postdischarge outcomes. For respiratory function comparisons, medical records of dogs having undergone a single lung lobectomy via median sternotomy (n=15) or intercostal thoracotomy (n=15) were reviewed. Twenty-three cases (16 dogs, 7 cats) were included. Pneumonectomy was performed for congenital (1 dog, 1 cat), neoplastic (8 dogs, 1 cat), and infectious (7 dogs, 5 cats) disease. Postoperative aspiration pneumonia occurred in 2 dogs; 15 of 16 dogs (94%) and 6/7 cats (86%) survived to hospital discharge. After pneumonectomy, dogs had a significantly higher postoperative PaO2 on 21% oxygen (P=.033) and lower postoperative A-a gradient (P=.004) compared to dogs undergoing single lung lobectomy. Survival times (right-censored at last follow-up) for dogs ranged from 2 days to 7 years (estimated median=1,868 days) and for cats from 1-585 days. Dogs and cats have acceptable respiratory function immediately postoperatively and most have protracted long-term survival after pneumonectomy for a variety of pulmonary diseases. © Copyright 2016 by The American College of Veterinary Surgeons.

Full Text Available Opioids are the most available medicines to get rid of any general severe pain and avoiding of any deleterious sequential that can worsen patient outcomes. Rational prescription of opioid analgesics with respect to the possibility of abuse is a big concern in the medical care costs. Zabol, where is located in eastern part of Iran and has common border with Afghanistanhas the most opioid traffic in the region. In this study the rational prescription of parenteral opioid in Amir-al-Momenin general hospital was investigated. A retrospective drug utilization review was performed on 509 in-patients who received parenteral opioids including Morphine, Pethidin, Pentazocin, Fentanyl, Alfentanil, Sufentanil and Methadone from March 21sttoSeptember 23rd, 2011. Multivariate conditional regression modeling was used to determine independent predictors for daily parenteral opioid consumption. Total daily parenteral opioid consumption was 38.63 DDDs/100bed-days for Morphine, Pethidine and Pentazocin and 84564.78 PFEQs/100bed-days for Fentanyl, Alfentanil and Sufentanil and 766 mg for Methadone. Pethidine was the most frequently prescribed parenteral opioid. Most patients who were prescribed by the intramuscular routes, ordered PRN. Daily parenteral opioid consumption was the highest in the emergency ward whereas it was considered as the lowest in the intensive care unit[ICU]. According to our findings, total daily parenteral opioid consumption was almost high in Amir-al-Momenin Hospital. Unlike to some relevant factors that can effect on the consumption of analgesic opioids like gender, age, drug-drug interaction and etc, we found no rational prescription and consumption in the mentioned hospital.

Pulmonary edema is the most common complication of left-sided heart failure in dogs and early detection is important for effective clinical management. In people, pulmonary edema is commonly diagnosed based on transthoracic ultrasonography and detection of B line artifacts (vertical, narrow-based, well-defined hyperechoic rays arising from the pleural surface). The purpose of this study was to determine whether B line artifacts could also be useful diagnostic predictors for cardiogenic pulmonary edema in dogs. Thirty-one normal dogs and nine dogs with cardiogenic pulmonary edema were prospectively recruited. For each dog, presence or absence of cardiogenic pulmonary edema was based on physical examination, heartworm testing, thoracic radiographs, and echocardiography. A single observer performed transthoracic ultrasonography in all dogs and recorded video clips and still images for each of four quadrants in each hemithorax. Distribution, sonographic characteristics, and number of B lines per thoracic quadrant were determined and compared between groups. B lines were detected in 31% of normal dogs (mean 0.9 ± 0.3 SD per dog) and 100% of dogs with cardiogenic pulmonary edema (mean 6.2 ± 3.8 SD per dog). Artifacts were more numerous and widely distributed in dogs with congestive heart failure (P dogs. © 2014 American College of Veterinary Radiology.

Houve diminuição do número e da duração das crises, superior a 75%, em três pacientes. Esses resultados são satisfatórios, considerando a gravidade dos quadros epilépticos e foram obtidos em pacientes com predomínio de alterações EEG lentas antes de iniciar o esquema terapêutico. Não se verificaram efeitos colaterais relevantes na época da administração parenteral. Em dois pacientes foi observado o aparecimento de crises tônicas coincidindo com o aumento de elementos EEG paroxísticos rápidos, localizados ou difusos.Changes of the clinical pictures and electroencephalographic patterns were studied in 9 patients suffering from epileptic seizures non responsive to common anticonvulsivants, when submitted to daily parenteral administration of diazepam (Valium and after its interruption. There was decrease of the number and duration of seizures, over to 75%, in 3 patients. These results can be considered as satisfatory, considering the intensity of the seizures. The best results were obtained in those patients which showed predominance of slow waves in the EEGs prior to the begin of the treatment. No side effects were observed during the treatment. Two patients developed tonic seizures coincident with the increasing of fast paroxistic EEG patterns, of localized or diffuse type.

Assessment of dentition in children under parenteral nutrition, risk factors for caries, and dental developmental abnormalities. The study involved 63 patients (aged 2.25-16.6 years), i.e. 32 subjects receiving parenteral nutrition for a mean period of 5.6±2.94 years, and 31 healthy control subjects. Oral hygiene (OHI-S, PL-I), gingival (GI), and dentition status (caries, DMFT/dmft, enamel defects, shape alterations), frequency of oral meals and frequency of cariogenic snacks consumption were evaluated. Medical records provided information on parenteral meals per week, age parenteral nutrition started, birth body mass, Apgar score, weight deficiency, and antibiotic therapy until aged 1 year. The Mann-Whitney test, chi-squared test, and Spearman rank correlation coefficient were used (p≤0.05). Dental developmental abnormalities occurred more often in PN subjects (71.87% vs. 25.80%). The prevalence of caries in PN (56.25% vs. 90.32%) and dmft (2.00±3.30 vs. 4.21±3.33) and DMFT (2.47±4.08 vs. 3.33±3.50) were lower. Positive caries Spearman's rank correlation coefficients: frequency of oral meals and frequency of cariogenic snacks consumption, and GI. Negative correlation coefficients: low birth body mass, antibiotic therapy, and low body mass in the first year of life. Positive dental developmental abnormality Spearman's coefficients: low birth body mass, Apgar score parenteral nutrition duration, low body mass and antibiotic therapy in the first year of life. Beta- lactam, aminoglycoside, glycopeptide and nitroimidazole treatments were related to enamel hypoplasia. Parenteral nutrition in childhood is related to the risk of dental developmental abnormalities, promoted by malnutrition and antibiotic therapy in infancy. Limiting the number of meals and cariogenic snacks, and most probably administration of antibiotics, decreases the risk of caries.

[Role of parenteral cephalosporins for outpatients treatment of infections].

OPAT (Outpatient Parenteral Antibiotic Therapy) arose in the early 1980s in the USA and later in many other countries from the primary consideration that outpatient treatment is more cost-effective than hospitalisation. Currently, several thousand patients undergo OPAT programmes all over the world and several different bacterial infections are included in the list of treatable diseases, especially those requiring long-term parenteral treatment such as osteomyelitis and soft tissue infections. All injectable antibiotics are suitable for OPAT according to their microbiological spectrum, although clearly some pharmacological properties make one antibiotic more preferable than another. Beta-lactams represent more than half of the antibiotic world market and two-thirds of them are cephalosporins. Such a widespread use of cephalosporins is certainly due to their wide antibacterial spectrum and good tolerability. Among third-generation cephalosporins, covering the majority of micro-organisms responsible for community-acquired infections, ceftriaxone is the only one with an 8-hour half-life, thereby permitting a single daily dose, which represents a great advantage when undertaking an OPAT programme. Analysis of antibiotic consumption used for OPAT therapies, based on data collected from the International OPAT Registry project, with the participation of many countries (USA, Canada, Britain, Argentina, etc.) including Italy, shows that ceftriaxone is the most widely used antibiotic for home therapy, clearly due to the above-mentioned properties.

The plasma concentrations of the trace metals zinc and copper were studied prospectively in 13 patients with gastrointestinal diseases treated with parenteral alimentation (TPA) for periods of from 8 days to 7 1/2 weeks. Plasma copper levels fell rapidly and consistently in all patients, with an overall rate of - 11 mug per 100 ml per week. Zinc concentrations declined in 10 of 13 patients at a more gradual rate. Analysis of the standard parenteral alimentation fluids revealed zinc content equivalent to 50% of the daily requirement and a negligible content of copper. From combined analysis of plasma zinc, hair zinc, and taste acuity, there is evidence that increased utilization or redistribution within the body may effect plasma concentrations in some patients. Neither an increase in urinary excretion nor a primary decrease in plasma binding proteins appeared to be a major factor in lowering plasma trace metal concentrations. These findings indicate that a marked decrease in plasma copper is regular and a decline in plasma zinc is common during TPA using fluids unsupplemented with trace metals. Supplementation of parenteral alimentation fluids with the trace metals zinc and copper is recommended.

the precise role of parenteral nutrition in the management of oncologic patients with intestinal occlusion is not well defined yet. We aimed to identify the effects of parenteral nutrition in these patients regarding prognosis. 55 patients with intestinal occlusion and peritoneal carcinomatosis were included. Parenteral nutrition aimed at 20-35 kcal/Kg/day, and 1.0 g/kg/day of amino-acids. Weight, body mass index, type of tumor, type of chemotherapy, and ECOG among others were recorded and analyzed. 69.1% of the patients had gastrointestinal tumors, 18.2% gynecologic and 12.7% others. Age was 60 ± 13y, baseline ECOG 1.5 ± 0.5 and body mass index 21.6 ± 4.3. Malnutrition was present in 85%. Survival from the start of parenteral nutrition was not significant when considering baseline ECOG (log rank = 0.593, p = 0.743), previous lines of chemotherapy (log rank = 2.117, p = 0.548), baseline BMI (log rank = 2.686, p = 0.261), or type of tumor (log rank = 2.066, p = 0.356). Survival in patients who received home parenteral nutrition after hospital discharge was higher than those who stayed in-hospital (log rank = 7.090, p = 0.008). Survival in patients who started chemotherapy during or after parenteral nutrition was higher than those who did not so (log rank = 17.316, p Parenteral nutrition in patients with advanced cancer and intestinal occlusion is safe, and in tho se who respond to chemotherapy, further administration of home parenteral nutrition together with chemotherapy may enhance prolonged survival.

Abunnaja, Salim; Cuviello, Andrea; Sanchez, Juan A.

2013-01-01

Nutritional support of surgical and critically ill patients has undergone significant advances since 1936 when Studley demonstrated a direct relationship between pre-operative weight loss and operative mortality. The advent of total parenteral nutrition followed by the extraordinary progress in parenteral and enteral feedings, in addition to the increased knowledge of cellular biology and biochemistry, have allowed clinicians to treat malnutrition and improve surgical patient’s outcomes. We reviewed the literature for the current status of perioperative nutrition comparing parenteral nutrition with enteral nutrition. In a surgical patient with established malnutrition, nutritional support should begin at least 7–10 days prior to surgery. Those patients in whom eating is not anticipated beyond the first five days following surgery should receive the benefits of early enteral or parenteral feeding depending on whether the gut can be used. Compared to parenteral nutrition, enteral nutrition is associated with fewer complications, a decrease in the length of hospital stay, and a favorable cost-benefit analysis. In addition, many patients may benefit from newer enteral formulations such as Immunonutrition as well as disease-specific formulations. PMID:23429491

To investigate effects of IV administration of dextrose on coagulation in healthy dogs. 7 dogs. Thromboelastography and coagulation panel analysis were used to assess coagulation. Samples (S1 through S9) were collected during the study phases: phase 0 (S1 [baseline]); phase 1 (S2 and S3), infusion of crystalloid fluid without dextrose; phase 2 (S4 and S5), high-rate dextrose infusion; phase 3 (S6, S7, and S8), moderate-rate dextrose infusion; and phase 4 (S9), discontinuation of fluids for 24 hours. In phase 3, dogs were allocated to 2 groups; 1 was administered dextrose at a rate comparable to total parental nutrition (40% of resting energy requirement; group A), and 1 was administered dextrose at rates equaling 70% to 90% of resting energy requirement (group B). Blood glucose concentration was measured every 2 hours. No dogs had clinically relevant sustained hyperglycemia. Maximum amplitude and elastic shear modulus were significantly lower at S6 than at S1 through S4. Concentration of D-dimer was significantly higher at S6 than at S1, S3, and S4 and significantly higher at S5 than at S3. Prothrombin time was significantly prolonged at S3, S5, S7, S8, and S9, compared with the value at S1. Activated partial thromboplastin time was significantly prolonged at S5 and S6, compared with values at S1, S2, S3, S4, and S9. IV administration of dextrose to healthy dogs at rates comparable to or higher than those for conventional parenteral nutrition resulted in mild but clinically unimportant interference with coagulation.

Short bowel syndrome is a severe malabsorption disorder, and prolonged parenteral nutrition is essential for survival in some cases. Among the undesirable effects of long-term parenteral nutrition is an increase in proinflammatory cytokines. The aim of the present study was to measure the serum levels of interleukin-6, interleukin-10, tumor necrosis factor alpha, and transforming growth factor beta, in patients with short bowel syndrome on cyclic parenteral nutrition and patients who had previously received but no longer require parenteral nutrition. The study was cross-sectional and observational. Three groups were studied as follows: Parenteral nutrition group, 9 patients with short bowel syndrome that receive cyclic parenteral nutrition; Oral nutrition group, 10 patients with the same syndrome who had been weaned off parenteral nutrition for at least 1 year prior to the study; Control group, 13 healthy adults, matched for age and sex to parenteral and oral groups. The following data were collected: age, tobacco use, drug therapies, dietary intake, body weight, height, blood collection. All interleukins were significantly higher in the parenteral group compared with the control group as follows: interleukin-6: 22 ± 19 vs 1.5 ± 1.4 pg/mL, P= .0002; transforming growth factor β: 854 ± 204 vs 607 ± 280 pg/mL, P= .04; interleukin-10: 8 ± 37 vs 0.6 ± 4, P= .03; tumor necrosis factor α: 20 ± 8 vs 8 ± 4 pg/mL, Pparenteral nutrition in short bowel syndrome patients, regardless of its duration, increases serum proinflammatory cytokines.

Parenteral nutrition (PN) may be provided through compounded or premixed solutions. To determine the proportion of stable custom-compounded PN prescriptions that would fit within a 20% deviance of an existing premixed PN solution. A retrospective study design was used. Inpatients who received PN in non-critical care units in the preceding year were screened for eligibility. Results are reported descriptively as means (95% confidence intervals) and proportions. We reviewed 97 PN prescriptions that met inclusion criteria. Stable hospital PN prescriptions compared with the reference premixed prescription provided 1838 (1777-1898) vs 1843 (1781-1905) kcal/d, P = .43; dextrose, 266 (254-277) vs 225 (216-234) g/d, P magnesium, 5.4 (4.8-5.4) vs 7.6 (7.4-7.9) mmol/L. Calories and protein were remarkably similar, but dextrose, lipid, and electrolytes differed between hospital PN and the reference premixed prescription. We believe that there may be a role for premixed solutions in quaternary centers in stable non-critically ill patients. © 2016 American Society for Parenteral and Enteral Nutrition.

In intensive care patients parenteral nutrition (PN) should not be carried out when adequate oral or enteral nutrition is possible. Critically ill patients without symptoms of malnutrition, who probably cannot be adequately nourished enterally for a period of <5 days, do not require full PN but should be given at least a basal supply of glucose. Critically ill patients should be nourished parenterally from the beginning of intensive care if they are unlikely to be adequately nourished orally or enterally even after 5-7 days. Critically ill and malnourished patients should, in addition to a possible partial enteral nutrition, be nourished parenterally. Energy supply should not be constant, but should be adapted to the stage, the disease has reached. Hyperalimentation should be avoided at an acute stage of disease in any case. Critically ill patients should be given, as PN, a mixture consisting of amino acids (between 0.8 and 1.5 g/kg/day), carbohydrates (around 60% of the non-protein energy) and fat (around 40% of the non-protein energy) as well as electrolytes and micronutrients.

Hospital information system data of cerebral infaction patients who received parenterally administered Shuxuetong was analyzed. This provided frequency data regarding patients' conditions and related information in order to provide a clinical reference guide. In this study, HIS data from 18 hospitals was analyzed. Patients receiving parenterally administered Shuxuetong for the treatment of cerebral infarction were included. Information on age, gender, costsand route of administration were collated. The average age of patients was 66 years old. Days of hospitalization ranged from 15 to 28 days. The majority of patients were classified as having phlegm and blood stasis syndrome, which is inaccordance with the indications for this drug. The most commonly used drugs used in combination with parenterally administered Shuxuetong were: aspirin, insulin and heparin. Patients with cerebral infarction crowd using parenterally administered Shuxuetong were a mostly elderly population, with an average age of 66. Although generally use was in accordance with indications, dosage, and route of administration, there were however some discrepancies. Therefore, doctors need to pay close attention to guidelines and closely observe patients when using parenterally administered Shuxuetong and to consider both the clinical benefits and risks.

This review highlights current methods and strategies for accelerated in-vitro drug release testing of extended-release parenteral dosage forms such as polymeric microparticulate systems, lipid microparticulate systems, in-situ depot-forming systems and implants. Extended-release parenteral dosage forms are typically designed to maintain the effective drug concentration over periods of weeks, months or even years. Consequently, 'real-time' in-vitro release tests for these dosage forms are often run over a long time period. Accelerated in-vitro release methods can provide rapid evaluation and therefore are desirable for quality control purposes. To this end, different accelerated in-vitro release methods using United States Pharmacopeia (USP) apparatus have been developed. Different mechanisms of accelerating drug release from extended-release parenteral dosage forms, along with the accelerated in-vitro release testing methods currently employed are discussed. Accelerated in-vitro release testing methods with good discriminatory ability are critical for quality control of extended-release parenteral products. Methods that can be used in the development of in-vitro-in-vivo correlation (IVIVC) are desirable; however, for complex parenteral products this may not always be achievable. © 2012 The Authors.

To review the benefits of enteral nutrition in contrast to the inflammatory consequences of administration of parenteral nutrition and enteral deprivation. To present the most recent evidence for the mechanisms of these immunologic changes and discuss potential areas for modification to decrease infectious complications of its administration. There is significant data supporting the early initiation of enteral nutrition in both medical and surgical patients unable to meet their caloric goals via oral intake alone. Despite the preference for enteral nutrition, some patients are unable to utilize their gut for nutritious gain and therefore require parenteral nutrition administration, along with its infectious complications. The mechanisms behind these complications are multifactorial and have yet to be fully elucidated. Recent study utilizing both animal and human models has provided further information regarding parenteral nutrition's deleterious effect on intestinal epithelial barrier function along with the complications associated with enterocyte deprivation. Changes associated with parenteral nutrition administration and enteral deprivation are complex with multiple potential areas for modification to allow for safer administration. Recent discovery of the mechanisms behind these changes present exciting areas for future study as to make parenteral nutrition administration in the enterally deprived patient safer.

Despite limitations of glass packaging for vaccines, the industry has been slow to implement alternative formats. Polymer containers may address many of these limitations, such as breakage and delamination. However, the ability of polymer containers to achieve cost of goods sold (COGS) and total cost of delivery (TCOD) competitive with that of glass containers is unclear, especially for cost-sensitive low- and lower-middle-income countries. COGS and TCOD models for oral and parenteral vaccine packaging formats were developed based on information from subject matter experts, published literature, and Kenya's comprehensive multiyear plan for immunization. Rotavirus and inactivated poliovirus vaccines (IPV) were used as representative examples of oral and parenteral vaccines, respectively. Packaging technologies evaluated included glass vials, blow-fill-seal (BFS) containers, preformed polymer containers, and compact prefilled auto-disable (CPAD) devices in both BFS and preformed formats. For oral vaccine packaging, BFS multi-monodose (MMD) ampoules were the least expensive format, with a COGS of $0.12 per dose. In comparison, oral single-dose glass vials had a COGS of $0.40. BFS MMD ampoules had the lowest TCOD of oral vaccine containers at $1.19 per dose delivered, and ten-dose glass vials had a TCOD of $1.61 per dose delivered. For parenteral vaccines, the lowest COGS was achieved with ten-dose glass vials at $0.22 per dose. In contrast, preformed CPAD devices had the highest COGS at $0.60 per dose. Ten-dose glass vials achieved the lowest TCOD of the parenteral vaccine formats at $1.56 per dose delivered. Of the polymer containers for parenteral vaccines, BFS MMD ampoules achieved the lowest TCOD at $1.89 per dose delivered, whereas preformed CPAD devices remained the most expensive format, at $2.25 per dose delivered. Given their potential to address the limitations of glass and reduce COGS and TCOD, polymer containers deserve further consideration as alternative

A review of gallbladder scintigraphy in patients with potentially compromised hepatobiliary function revealed two groups in whom cholecystitis might be mistakenly diagnosed. In 200 consecutive hospitalized patients studied with technetium-99m-PIPIDA for acute cholecystitis or cholestasis, there were 41 alcoholics and 17 patients on total parenteral nutrition. In 60% of the alcoholics and 92% of those on parenteral nutrition, absent or delayed visualization of the gallbladder occurred without physical or clinical evidence of cholecystitis. A cholecystagogue, sincalide, did not prevent the false-positive features which presumably are due to altered bile flow kinetics related to alcoholism and parenteral nutrition. Four patients on parenteral nutrition undergoing cholecystectomy for suspected cholecystitis had normal gallbladders filled with jellylike viscous thick bile. A positive (nonvisualized or delayed visualized) gallbladder PIPIDA scintigram in these two populations should not be interpreted as indicating a need for cholecystectomy

During hospitalization in a pediatric intensive care unit (PICU), critically ill children are fed artificially. Administered via the preferred enteral route, caloric targets are often not reached. Hence, parenteral nutrition is given to this patient population. In this review we analyzed the available evidence from randomized controlled trials (RCTs) that supports the use of parenteral nutrition in children during critical illness. A search strategy in Ovid MEDLINE and Ovid EMBASE was created and trial registries were screened to identify the relevant RCTs. Studies were included if they were randomized controlled trials, involved pediatric patients admitted to PICU, and compared different dosing/compositions of parenteral nutrition. Descriptive studies and reviews were excluded. Of the 584 articles identified by the search strategy, only 114 articles were retained after title screening. Further abstract and full text screening identified 6 small RCTs that compared two dosing/composition strategies of parenteral nutrition. These trials reported differences in surrogate endpoints without an effect on hard clinical endpoints. The RCTs observed improvements in these surrogate endpoints with the use of more calories or when parenteral glutamine or fish oil was added. The few RCTs suggest that surrogate endpoints can be affected by providing parenteral nutrition to critically ill children, but the studies were not statistically powered to draw meaningful clinical conclusions. Large RCTs with clinically relevant outcome measures are urgently needed to support the current nutritional guidelines that advise the use of parenteral nutrition in the PICU.

Parenteral nutrition lipid emulsions made from various plant oils contain steroidal compounds, called phytosterols. During parenteral administration of lipid emulsions, phytosterols can reach levels in the blood that are many fold higher than during enteral administration. The elevated phytosterol levels have been associated with the development of liver dysfunction and the rare development of liver failure. There is limited information available in the literature related to phytosterol concentrations in lipid emulsions. The objective of the current study was to validate an assay for steroidal compounds found in lipid emulsions and to compare their concentrations in the most commonly used parenteral nutrition lipid emulsions: Liposyn® II, Liposyn® III, Lipofundin® MCT, Lipofundin® N, Structolipid®, Intralipid®, Ivelip® and ClinOleic®. Our data demonstrates that concentrations of the various steroidal compounds varied greatly between the eight lipid emulsions, with the olive oil-based lipid emulsion containing the lowest levels of phytosterols and cholesterol, and the highest concentration of squalene. The clinical impression of greater incidences of liver dysfunction with soybean versus MCT/LCT and olive/soy lipid emulsions may be reflective of the levels of phytosterols in these emulsions. This information may help guide future studies and clinical care of patients with lipid emulsion-associated liver dysfunction. PMID:23016123

Maternal and perinatal morbidity and mortality remain major challenges in the delivery of safe maternity care worldwide. Anaemia in pregnancy is an important contributor to this dismal picture, especially where blood transfusion services are poorly developed. An early diagnosis and treatment of iron deficiency anaemia in pregnancy using the new generation dextran-free parenteral iron preparations can save lives and reduce morbidity in selected pregnancies. It is time to cast aside the fears associated with the use of the old parenteral iron preparations which were associated a high incidence of anaphylaxis, and embrace the use of new parenteral iron products which have better side effect profiles and can deliver total dose infusions without the need for test dosing. In selected women, the benefits of this treatment far outweigh any disadvantages.

Background and Aims Serum zinc, copper and selenium are measured in patients prior to commencing on parenteral nutrition; however, their interpretation can be difficult due to acute phase reactions. We assessed (i) the relationship of raised C-reactive protein with trace elements and albumin (ii) benefits of measuring trace elements when C-reactive protein is raised in patients requiring short-term parenteral nutrition. Methods Samples were collected for zinc, copper, selenium and albumin at baseline and then every two weeks and correlated with C-reactive protein results in patients on parenteral nutrition. Results were categorized into four groups based on the C-reactive protein concentrations: (i)  0.05), whereas selenium and albumin were lower in the group with C-reactive protein > 40 mg/L ( P parenteral nutrition, measurement of C-reactive protein is essential when interpreting zinc and selenium but not copper results. Routine measurement of trace elements prior to commencing parenteral nutrition has to be considered on an individual basis in patients with inflammation.

Management of Hyperglycemia During Enteral and Parenteral Nutrition Therapy

Science.gov (United States)

Umpierrez, Guillermo E.

2013-01-01

Hyperglycemia is a frequent complication of enteral and parenteral nutrition in hospitalized patients. Extensive evidence from observational studies indicates that the development of hyperglycemia during parenteral and enteral nutrition is associated with an increased risk of death and infectious complications. There are no specific guidelines recommending glycemic targets and effective strategies for the management of hyperglycemia during specialized nutritional support. Managing hyperglycemia in these patients should include optimization of carbohydrate content and administration of intravenous or subcutaneous insulin therapy. The administration of continuous insulin infusion and insulin addition to nutrition bag are efficient approaches to control hyperglycemia during parenteral nutrition. Subcutaneous administration of long-acting insulin with scheduled or corrective doses of short-acting insulin is superior to the sliding scale insulin strategy in patients receiving enteral feedings. Randomized controlled studies are needed to evaluate safe and effective therapeutic strategies for the management of hyperglycemia in patients receiving nutritional support. PMID:23065369

Familial subvalvular aortic stenosis (SAS) is one of the most common congenital heart defects in dogs and is an inherited defect of Newfoundlands, golden retrievers and human children. Although SAS is known to be inherited, specific genes involved in Newfoundlands with SAS have not been defined. We hypothesized that SAS in Newfoundlands is inherited in an autosomal dominant pattern and caused by a single genetic variant. We studied 93 prospectively recruited Newfoundland dogs, and 180 control dogs of 30 breeds. By providing cardiac screening evaluations for Newfoundlands we conducted a pedigree evaluation, genome-wide association study and RNA sequence analysis to identify a proposed pattern of inheritance and genetic loci associated with the development of SAS. We identified a three-nucleotide exonic insertion in phosphatidylinositol-binding clathrin assembly protein (PICALM) that is associated with the development of SAS in Newfoundlands. Pedigree evaluation best supported an autosomal dominant pattern of inheritance and provided evidence that equivocally affected individuals may pass on SAS in their progeny. Immunohistochemistry demonstrated the presence of PICALM in the canine myocardium and area of the subvalvular ridge. Additionally, small molecule inhibition of clathrin-mediated endocytosis resulted in developmental abnormalities within the outflow tract (OFT) of Xenopus laevis embryos. The ability to test for presence of this PICALM insertion may impact dog-breeding decisions and facilitate reduction of SAS disease prevalence in Newfoundland dogs. Understanding the role of PICALM in OFT development may aid in future molecular and genetic investigations into other congenital heart defects of various species.

Reversal of growth arrest in adolescents with Crohn's disease after parenteral alimentation.

Growth arrest and delayed onset of puberty often complicate childhood onset Crohn's disease of the small bowel (granulomatous enteritis). Nutritional deficits arising from inadequate dietary intake, malabsorption, and increased caloric needs may contribute to growth retardation. To assess whether a sustained high caloric and nitrogen intake could reestablish growth, 4 children with extensive Crohn's disease of the small bowel were studied before and after parenteral alimentation which was instituted for symtomatic disease control. Weight gain, positive nitrogen balance, and improved nutritional status were achieved during parenteral alimentation in each patient. In 2 patients weight gain was sustained using oral nutritional supplements, and a substantial increase in linear skeletal growth continued in the ensuing months. One patient entered puberty within 4 months of parenteral alimentation and another had the onset of menarche and the development of secondary sex characteristics 4 months after parenteral alimentation and resection of diseased bowel. Growth may be reestablished in some growth-arrested children if intake is sufficient to establish a sustained positive caloric and nitrogen balance. Nutritional requirements imposed by the demands of growth and active disease and often compounded by the catabolic effects of corticosteroids may be excessive; growth may occur only if these needs are met orally and/or parenterally.

A 1.5-year-old mixed-breed dog was examined because of a 1-month history of anorexia, vomiting, diarrhea, and weight loss. The dog was very thin on physical examination (body condition score, 3/9). Results of all diagnostic tests were within reference limits except intestinal thickening and lymphadenopathy were identified on abdominal ultrasound examination. During exploratory laparotomy, thickening at the ileocecal-colic junction and within the transverse colon and mesenteric lymphadenopathy were identified, and the ileocecal-colic junction was resected. Histopathologic evaluation of the ileocecal-colic junction and full-thickness biopsy specimens from other sites as well as results of a serum ELISA were diagnostic for gastrointestinal Pythium insidiosum infection. Pythiosis was initially treated medically with administration of itraconazole and terbinafine by mouth, but the colonic lesion was progressive with this regimen. Two months after diagnosis, a subtotal colectomy was performed; marginal excision (0.6 cm) was obtained at the aboral margin. The dog was treated with 3 doses of a pythiosis vaccine beginning approximately 2 weeks after surgery and was continued on itraconazole and terbinafine for 5 months. Parenteral and enteral nutrition as well as considerable general supportive care were required postoperatively. Six months after treatment, the dog had a normal serum ELISA titer. Two years after treatment, the dog had returned to preoperative weight and was clinically normal. This patient had an unusually positive therapeutic response to chronic, extensive, marginally excised gastrointestinal pythiosis.

Retrospective study to describe clinical experience with a portable single-use negative pressure wound therapy device after application of full-thickness meshed skin grafts to wounds on the distal extremities of seven dogs. Seven dogs were treated with portable NPWT after receiving skin grafts; six as the result of tumour resection and one for traumatic injury. Medical records were reviewed and data recorded on patient signalment, cause and location of wound, surgical technique, application and maintenance of portable NPWT, graft survival and outcome, and complications encountered with the system. NPWT was provided for between 4 and 7 days. Five patients were discharged from hospital during the treatment period. Application and maintenance of the portable device was technically easy and no major complications were encountered. Minor complications consisted of fluid accumulation in the evacuation tubing. All dogs achieved 100% graft survival. Application and maintenance of the portable device was technically straightforward. All dogs receiving portable NPWT after transfer of a free skin graft to the distal extremity had a successful outcome. © 2016 Australian Veterinary Association.

Sterilization of solutions for parenterals products. Problem analysis

Full Text Available The solutions for the formulation of parenteral products must be sterile before the aseptic formulation process. For this reason, different methods of sterilization referred in the literature are analyzed. Thermodynamic criteria that rule the sterilization are presented. Furthermore, previous experiences in the sterilization of solutions for the formulation of parental products in an autoclave are analyzed, that take large time of processing and only low volumes of solution can be handled. Using jacketed stirred tanks for the sterilization may solve the problem and, therefore, criteria for the design of the later that allow to process high volumes of solution for the formulation of parenteral products are shown.

Ten patients with radiation enteritis unresponsive to conventional medical and surgical therapy were put on long-term parenteral nutrition at home. Six of the patients are alive at home; four patients died, two from recurrent cancer. Some of the patients have been able to resume oral intake, but none have been able to discontinue parenteral nutrition. Fistulas healed or had a marked decrease in output. Two patients in our series were given prednisone and sulfasalazine without significant benefit, in contrast to previously reported clinical improvement of radiation enteritis with this therapy

Parenterally administered Mycobacterium bovis BCG vaccine confers only limited immune protection from pulmonary tuberculosis in humans. There is a need for developing effective boosting vaccination strategies. We examined a heterologous prime-boost regimen utilizing BCG as a prime vaccine and our recently described adenoviral vector expressing Ag85A (AdAg85A) as a boost vaccine. Since we recently demonstrated that a single intranasal but not intramuscular immunization with AdAg85A was able to induce potent protection from pulmonary Mycobacterium tuberculosis challenge in a mouse model, we compared the protective effects of parenteral and mucosal booster immunizations following subcutaneous BCG priming. Protection by BCG prime immunization was not effectively boosted by subcutaneous BCG or intramuscular AdAg85A. In contrast, protection by BCG priming was remarkably boosted by intranasal AdAg85A. Such enhanced protection by intranasal AdAg85A was correlated to the numbers of gamma interferon-positive CD4 and CD8 T cells residing in the airway lumen of the lung. Our study demonstrates that intranasal administration of AdAg85A represents an effective way to boost immune protection by parenteral BCG vaccination.

Single dose toxicity studies of landiolol hydrochloride (ONO-1101), a novel ultra short acting beta-blocker, were conducted in Sprague-Dawley (SD) rats and beagle dogs. ONO-1101 was administered intravenously at a dose level of 37.5, 75, 150 or 300 mg/kg to rats of both sexes and 25, 50 or 100 mg/kg to male dogs. In the rat study, 5/6 males in the 150 mg/kg group and all animals in the 300 mg/kg group died during or right after administration. Survivors in the 150 mg/kg group showed temporal hypoactivity, bradypnea, dyspnea, tremor, loss of righting reflex and reddish lacrimation up to 5 min after injection. One male in the 150 mg/kg group had a tendency of suppression on body weight gain. No effects on clinical signs and body weight gain were seen in the 75 mg/kg group or lower. Necropsy findings showed only red tear in the majority of the decedents. In the dog study, all animals died within 6 min after administration in the 100 mg/kg group, showed ataxic gait, rolling and tachypnea followed by bradypnea and gasping/apnea. Incontinence of urine, defecation and vocalization were also seen in each one of two animals before death. Temporal hypoactivity was seen 1 min after administration in the 50 mg/kg group. No clinical signs were seen in the 25 mg/kg group. ONO-1101 did not affect bodyweight or food consumption. Necropsy findings of the decedents showed no abnormalities. It is indicated that the minimum lethal doses are 150 mg/kg in rats and 100 mg/kg in dogs.

The physicochemical stability and availability of 0.1% 5-fluorouracil solutions in D5W and a typical total parenteral nutrition solution (hypertonic dextrose and crystalline amino acids) were studied in both glass and Viaflex delivery systems. Serial samples collected over a 48-hour period were assayed for 5-fluorouracil concentration using a high performance liquid chromatographic technique. Changes in the pH as well as precipitate formation were also investigated. There was no reduction in the amount of 5-fluorouracil at 48 hours in either the glass or plastic system, regardless of whether the drug was added to D5W or to the total parenteral nutrition solution. No pH changes or precipitates were observed. These findings indicate that 5-fluorouracil is compatible with and available from total parenteral solutions of hypertonic dextrose and amino acid in both plastic and glass containers. Use of such a system would allow for (1) a reduction in vascular access in patients receiving both treatments and (2) continued administration of nutritional support without the requirement for additional fluid volume.

Full Text Available In intensive care patients parenteral nutrition (PN should not be carried out when adequate oral or enteral nutrition is possible. Critically ill patients without symptoms of malnutrition, who probably cannot be adequately nourished enterally for a period of <5 days, do not require full PN but should be given at least a basal supply of glucose. Critically ill patients should be nourished parenterally from the beginning of intensive care if they are unlikely to be adequately nourished orally or enterally even after 5–7 days. Critically ill and malnourished patients should, in addition to a possible partial enteral nutrition, be nourished parenterally. Energy supply should not be constant, but should be adapted to the stage, the disease has reached. Hyperalimentation should be avoided at an acute stage of disease in any case. Critically ill patients should be given, as PN, a mixture consisting of amino acids (between 0.8 and 1.5 g/kg/day, carbohydrates (around 60% of the non-protein energy and fat (around 40% of the non-protein energy as well as electrolytes and micronutrients.

In 8 dogs a colonic pouch with fistula was surgically created. Mucin secretion was measured by washing mucus out of the pouch and then, after a number of chemical steps, by determining the turbidity with spectrophotometry. The movement of tantalum particles insufflated into the canine rectum during periods of absence of contractions was correlated with mucus secretion in the pouch. Correlations were made after parenteral injection of secretin which increased movement of tantalum particles and production of mucin, and after injection of glucagon, which stopped movement of the particles and decreased mucin secretion in the pouch. Movement of tantalum was also observed when the particles were insufflated into the canine rectum on top of an applied layer of water-soluble jelly. (Auth.)

Minimizing systemic infection during complete parenteral alimentation of small infants

Science.gov (United States)

Nelson, R.

1974-01-01

A regimen of parenteral alimentation for infants was designed to eliminate as many factors responsible for infection as possible. The most important features of the feeding regimen were as follows. (1) Infants were fed via indwelling silastic catheters inserted into the superior vena cava or the right atrium by a cutdown operation. (2) The parenteral feeding was fat free to simplify the administration system. Y connectors and 2- or 3-way taps were avoided. (3) Extreme care was taken of junctions within the infusion system. Only certain members of the hospital staff were allowed to break such junctions, e.g. during the changing of packs of solution or of the giving sets. These junctions were sprayed with antibacterial aerosols. (4) The hypertonic solutions of nutrients were prepared in plastic packs, which do not require ventilation. The infusion system was therefore not contaminated by the entry of unsterile outside air. (5) The infused solutions were passed through 0·22 μm millipore filters before entering the patient's blood stream. There was an infection rate of 9% which was less than the 25 to 45% infection rate previously reported during parenteral feeding through indwelling venous catheters, and is also less than that associated with ventriculoatrial shunts for hydrocephalus. There was no case of systemic candidiasis, which is the most frequent and most serious infection associated with parenteral feeding. PMID:4206445

Parenteral nutrition became a routine therapeutic option in malnourished patients, if conventional nutritional enteral support is not effective. Cachexia and malnutrition prolong the wound healing, contribute to immunosuppression, increase morbidity and the cost of treatment. Using of a malnutrition protocol as a screening tool is necessary to sort out malnourished patients. Parenteral nutrition is therefore an important part of the multimodal therapy and from the medical and the ethical point of view is a great mistake not to feed a patient. (author)

Iodine-123 phenylpentadecanoic acid: detection of acute myocardial infarction and injury in dogs using an iodinated fatty acid and single-photon emission tomography

International Nuclear Information System (INIS)

Rellas, J.S.; Corbett, J.R.; Kulkarni, P.

1983-01-01

The ability of an iodinated fatty acid, iodine-123 phenylpentadecanoic acid (1-123 PPA), and single-photon emission computed tomography (SPECT) to detect myocardium injured by temporary or permanent coronary arterial occlusion was evaluated. In 5 control dogs, 11 dogs that underwent 90 to 120 minutes of fixed left anterior descending coronary artery (LAD) occlusion, and 8 dogs that underwent 90 minutes of temporary LAD occlusion and up to 90 minutes of reflow, 2 to 6 mCi of I-123 PPA were injected and the dogs were imaged with SPECT. Control dogs showed relatively uniform uptake and clearance of I-123 PPA in similar left ventricular (LV) regions. Dogs with permanent LAD occlusion were identified by computer algorithm as having regions of decreased I-123 PPA uptake in the infarct-related area and a reduced rate of I-123 PPA clearance (-9.4% in infarct sectors [washin], +3.7% in sectors adjacent to the area of infarction, and +15.4% in control LV sectors [p less than 0.01]). Dogs with temporary LAD occlusion and reperfusion had decreased clearance of I-123 PPA from the regions with infarction; I-123 PPA clearance was -5.2 +/- 16.4% in infarct sectors, 12.7 +/- 7.4% in periinfarct zones, and 30.4 +/- 12% in control LV regions. These data demonstrate that tomographic analysis of I-123 PPA uptake and clearance permits the relatively noninvasive detection of LV myocardium injured by permanent or temporary LAD occlusion and reperfusion

Home parenteral nutrition (HPN) was introduced as a treatment modality in the early 1970s primarily for the treatment of chronic intestinal failure in patients with benign disease. The relatively low morbidity and mortality associated with HPN has encouraged its widespread use in western countries....... Thus there is huge clinical experience, but there are still few controlled clinical studies of treatment effects and management of complications. The purpose of these guidelines is to highlight areas of good practice and promote the use of standardized treatment protocols between centers...

Effects of whole-body, ionizing radiation on the semen in beagle dogs

International Nuclear Information System (INIS)

Day, P.A.

1988-01-01

Six beagle dogs were exposed to a total dose of 183 R of gamma radiation at a dose rate of 1 R/day, while three other dogs were exposed to a single dose of 100 R. Weekly semen analysis was performed on all irradiated dogs plus four nonirradiated dogs. Semen volume, sperm concentration, total sperm count, sperm motility and sperm head morphometry were examined. Dogs exposed to chronic radiation showed a severe decline in sperm numbers, detected after seven weeks of exposure. Sperm concentration and total sperm count were the first parameters affected and were the only parameters consistently affected. The dogs exposed to 100 R as a single dose, did not show a significant decline in sperm numbers. During a 36 week recovery period, the chronically irradiated dogs did show a slight increase in sperm numbers, but they never approached pre-exposure levels

New perspective for nutritional support of cancer patients: Enteral/parenteral nutrition.

Cancer and its treatment result in severe biochemical and physiological alterations associated with a deterioration of quality of life (QoL). Cancer-related malnutrition may evolve into cancer cachexia due to complex interactions between pro-inflammatory cytokines and the host metabolism. Depending on the type of cancer treatment (either curative or palliative), the clinical condition of the patient and nutritional status, adequate and patient-tailored nutritional intervention should be prescribed (diet counseling, oral supplementation, enteral or total parenteral nutrition). Nutritional support has been widely advocated as adjunctive therapy for a variety of underlying illnesses, including surgery and medical oncotherapy (radiation or chemotherapy for cancer). Glutamine, n-3 fatty acids and probiotics/prebiotics are therapeutic factors that potentially modulate gastrointestinal toxicity related to cancer treatments. Enteral and parenteral nutrition may help improve patient survival, functional status and QoL, yet the benefits appear to be primarily limited to patients with good functional status and with gastrointestinal disease affecting nutritional intake. Parenteral nutrition offers the possibility of increased or maintenance of the nutrient intake in patients for whom normal food intake is inadequate and for whom enteral nutrition is not feasible, is contraindicated or is not accepted by the patient. This article reviews evidence on issues relevant to enteral and parenteral nutrition in patients with cancer.

Reported are results obtained from studies into oral and parenteral immunisation of calf. The approaches had included the use of live (Smd) or dead antigen from Salmonella (S.) dublin and a combination of the two immunisation methods. Live antigen (Smd) was superior to thermally activated dead antigen, when the oral route was used to prevent S.-dublin injection of calves. The above findings were supported by results from analogous studies in which S. typhimurium and S. dublin or live antigen (Smd) or dead antigen, made of the two, had been applied to mice. (One single subcutaneous) parenteral administration did hardly reveal any difference in favour of live vaccine (Smd). Parenteral administration of live or dead antigen proved to be less effective than repeated oral immunisation, particularly when live vaccine (Smd) was used. Immunity not less than up to six months of age against S. dublin wild strain infection can be provided for young calves by oral immunisation, with Smd vaccine (5. 1010 to 1. 1011 live germs/d) being given on ten consecutive days. Calves orally immunised with live antigen (ten repetitive applications of Smd mutants) are likely to develop an antibody titre (H-agglutinins) against S. dublin. Parenteral boostering,using live antigen, has been accompanied by sensitisation due to oral live antigen administration as well as by dose dependence, as was seen from the bactericidal values. Sensitisation was established from orally immunised calves up to three months old (typical booster reaction). Some of it was attributabale to confrontation with wild strains of Salmonella. The H-agglutinin titres of animals aged threemonths in a calf herd with salmonelloses in which all animals had been orally Smd-immunised were close to those recorded from calves in stocks with no salmonellosis occurrence. Under the conditions of oral immunisation, there had obviously been no action of the wild strain which might have triggered intensive antibody formation.

Moreover, many studies demonstrated the in vitro and in vivo parenteral nutrition -drugs interactions, especially with antiepileptics. There was no evidence supporting the existence of parenteral nutrition-antiepileptic drugs interaction. The issue has not been studied in formal researches, but several case reports and anecdotes demonstrate this drug-nutrition interaction. However, alteration in the drug-free fraction result from parenteral nutrition-drug (i.e. antiepileptics) interactions may necessitate scrupulous reassessment of drug dosages in patients receiving these therapies. This reassessment may be particularly imperative in certain clinical situations

Thirty-seven dogs with histologically or cytologically confirmed malignant tumors treated with single-agent mitoxantrone at 5 mg/m 2 were evaluated in a retrospective study assessing the correlation between body weight and neutropenia associated with a single dose of mitoxantrone in dogs. Overall, eight dogs (21%) experienced grade 3 neutropenia and five dogs (14%) experienced grade 4 neutropenia on day 7 following mitoxantrone chemotherapy. Dogs ≤10 kg body weight were significantly more likely to develop grade 3 or 4 neutropenia (5.8 relative risk; 95% confidence interval, 2.6-12.9; P 10 kg. Dogs ≤15 kg body weight were significantly more likely to develop grade 3 or 4 neutropenia (8.1 relative risk; 95% confidence interval, 2.1-31.3; P 15 kg. Of the 13 patients who developed grade 3 or 4 neutropenia, 6 (46%) were hospitalized for clinical signs related to neutropenia. Based on the severity of neutropenia and the resulting hospitalization seen in dogs ≤10 kg, a dose reduction could be considered for the initial dose of mitoxantrone, and clinicians should be aware of the increased risk of neutropenia in patients 10.1 to ≤15 kg.

Iron is not routinely added to parenteral nutrition (PN) formulations in the United States because of the risk of anaphylaxis and concerns about incompatibilities. Studies have shown that iron dextran in non-lipid-containing PN solutions is safe. Data are limited on iron status, prevalence of iron deficiency anemia (IDA), and efficacy of intravenous iron infusion in long-term home PN (HPN). We aimed to determine the incidence of IDA and to examine the effectiveness of parenteral iron replacement in patients receiving HPN. Medical records of patients receiving HPN at the Mayo Clinic from 1977 to 2010 were reviewed. Diagnoses, time to IDA development, and hemoglobin, ferritin, and mean corpuscular volume (MCV) values were extracted. Response of iron indices to intravenous iron replacement was investigated. Of 185 patients (122 women), 60 (32.4%) were iron deficient. Five patients were iron deficient, and 18 had unknown iron status before HPN. Of 93 patients who had sufficient iron storage, 37 had IDA development after a mean of 27.2 months (range, 2-149 months) of therapy. Iron was replaced by adding maintenance iron dextran to PN or by therapeutic iron infusion. Patients with both replacement methods had significant improvement in iron status. With intravenous iron replacement, mean ferritin increased from 10.9 to 107.6 mcg/L (P Parenteral and Enteral Nutrition.

Five patients who would have been unable to survive because of intestinal complications of radiation therapy were able to lead an otherwise normal life with the use of parenteral nutrition administered at home. One patient died of recurrent carcinoma of the cervix after 14 months. Another patient died as the result of a totally avoidable pharmaceutical error after 2 1/2 years. The remaining three are still disease free without morbidity relating to the parenteral nutrition

Introduction Whether parenteral nutrition benefits growth of very low birth weight (VLBW) preterm infants in the setting of rapid enteral feeding advancement is unclear. Our aim was to examine this issue using data from Japan, where enteral feeding typically advances at a rapid rate. Methods We studied 4005 hospitalized VLBW, very preterm (23–32 weeks' gestation) infants who reached full enteral feeding (100 ml/kg/day) by day 14, from 75 institutions in the Neonatal Research Network Japan (2003–2007). Main outcomes were weight gain, head growth, and extra-uterine growth restriction (EUGR, measurement parenteral nutrition. Adjusting for maternal, infant, and institutional characteristics, infants who received parenteral nutrition had greater weight gain [0.09 standard deviation (SD), 95% CI: 0.02, 0.16] and head growth (0.16 SD, 95% CI: 0.05, 0.28); lower odds of EUGR by head circumference (OR 0.66, 95% CI: 0.49, 0.88). No statistically significant difference was seen in the proportion of infants with EUGR at discharge. SGA infants and infants who took more than a week until full feeding had larger estimates. Discussion Even in infants who are able to establish enteral nutrition within 2 weeks, deprivation of parenteral nutrition in the first weeks of life could lead to under nutrition, but infants who reached full feeding within one week benefit least. It is important to predict which infants are likely or not likely to advance on enteral feedings within a week and balance enteral and parenteral nutrition for these infants. PMID:24586323

Full Text Available Introduction: The incidence of malnutrition in hospitalized patients is reported to be high. In particular, patients with esophageal cancer are prone to malnutrition, due to preoperative digestive system dysfunctions and short-term non-oral feeding postoperatively. Selection of an appropriate method for feeding in the postoperative period is important in these patients.   Materials and Methods: In this randomized clinical trial, 40 patients with esophageal cancer who had undergone esophagectomy between September 2008 and October 2009 were randomly assigned into either enteral feeding or parenteral feeding groups, with the same calorie intake in each group. The level of serum total protein, albumin, prealbumin, transferrin, C3, C4 and hs-C-reactive protein          (hs-CRP, as well as the rate of surgical complications, restoration of bowel movements and cost was assessed in each group.   Results: Our results showed that there was no significant difference between the groups in terms of serum albumin, prealbumin or transferrin. However, C3 and C4 levels were significantly higher in the enteral feeding group compared with the parenteral group, while hs-CRP level was significantly lower in the enteral feeding group. Bowel movements were restored sooner and costs of treatment were lower in the enteral group. Postoperative complications did not differ significantly between the groups. There was one death in the parenteral group 10 days after surgery due to myocardial infarction.   Conclusion:  The results of our study showed that enteral feeding can be used effectively in the first days after surgery, with few early complications and similar nutritional outcomes compared with the parenteral method. Enteral feeding was associated with reduced inflammation and was associated with an improvement in immunological responses, quicker return of bowel movements, and reduced costs in comparison with parenteral feeding.

Long-term follow-up studies after interventional therapy of patent ductus arteriosus (PDA) in dogs are rare. Transvenous PDA embolization with a single detachable coil is a highly effective method in patients with an angiographically determined PDA≤4.0 mm. Twenty-eight dogs with an angiographic PDA≤4.0 mm were included. Prospective follow-up study after PDA coil embolization. The median follow-up time was 792 days (range, 2-3, 248 days). The rate of complete closure demonstrated by Doppler color flow was 54% at day 3 after intervention and the final cumulative rate was 71%. The rate of complete closure was significantly different between small and moderately sized PDA over the study period (Pclosure, no recanalization was found. Disappearance of the continuous heart murmur was found in 89% after 3 days, and this increased to a final cumulative rate of 96%. Indexed left ventricular internal diameter in diastole (LVDd-I) decreased significantly (Pclosure in all small PDA but a residual shunt with mild hemodynamic consequences was present in half of the moderately sized PDA.

We have previously shown that substantial losses of fat-soluble (FS) vitamin A from parenteral alimentation solution occur due to adsorption in the intravenous tubing and photodegradation in the bottle. This study assessed the delivery of other vitamins, viz, FS vitamin E and water-soluble (WS) vitamin C, from parenteral alimentation solution. The solution containing 2.0 ml/L of an aqueous multivitamin infusion was infused at a constant rate of 10 ml/h using a standard intravenous administration set. Multiple aliquots of the solution from the bottle and the effluent obtained sequentially in a 24-h period were analyzed for concentrations of vitamins E and C. Both vitamins remained relatively stable in the bottle. A significant amount (12%) of vitamin E was lost in the intravenous tubing. No losses of vitamin C were incurred in the intravenous tubing. The data suggest that delivery of FS vitamin E from parenteral alimentation solutions is less than optimum because of adsorptive losses. Similar losses are not encountered with WS vitamin C.

Rabies in dogs can be controlled through mass vaccination. Oral vaccination of domestic dogs would be useful in the developing world, where greater vaccination coverage is needed especially in inaccessible areas or places with large numbers of free-roaming dogs. From this perspective, recent research has focused on development of new recombinant vaccines that can be administered orally in a bait to be used as adjunct for parenteral vaccination. One such candidate, a recombinant canine adenovirus type 2 vaccine expressing the rabies virus glycoprotein (CAV2-RG), is considered a promising option for dogs, given host specificity and safety. To assess the potential use of this vaccine in domestic dog populations, we investigated the prevalence of antibodies against canine adenovirus type 2 in South African dogs. Blood was collected from 241 dogs from the Gauteng and KwaZulu-Natal provinces. Sampled dogs had not previously been vaccinated against canine adenovirus type 1 (CAV1) or canine adenovirus type 2 (CAV2). Animals from both provinces had a high percentage of seropositivity (45% and 62%), suggesting that CAV2 circulates extensively among domestic dog populations in South Africa. Given this finding, we evaluated the effect of pre-existing CAV-specific antibodies on the efficacy of the CAV2-RG vaccine delivered via the oral route in dogs. Purpose-bred Beagle dogs, which received prior vaccination against canine parvovirus, canine distemper virus and CAV, were immunized by oral administration of CAV2-RG. After rabies virus (RABV) infection all animals, except one vaccinated dog, developed rabies. This study demonstrated that pre-existing antibodies against CAV, such as naturally occurs in South African dogs, inhibits the development of neutralizing antibodies against RABV when immunized with a CAV-based rabies recombinant vaccine.

In 50 patients aged between 3 and 84 years treated in a multidisciplinary Intensive Care Unit and receiving parenteral alimentation, deficiency in certain trace elements or electrolytes (Cu++, Zn++, Mn++, Co++, PO-4, Mg++) was prevented or treated by the administration of a glucose solution (MB 147 G) enriched in trace elements. The aim of the present study was to demonstrate, on the basis of assay of serum levels of the trace elements involved, with the exception of Mn and Co, the effectiveness of treatment. Reference values were determined on the one hand in healthy individuals for normal figures and secondly on subjects included in the study, already on parenteral alimentation for several days, before treatment with MB 147 G, in order to demonstrate the existence of a deficiency (patient control values). In the case of PO--4, however, the patient control values concerned at one and the same time subjects in the study before treatment with MB 147 G and other patients receiving parenteral alimentation who were not part of the trial. MB 147 G solution was presented in units of 500 ml associated with glucose of varying concentrations (15 p. 100, 30 p. 100, 50 p. 100). The average daily amount administered, over a period of 236 days, was 3 unites per 24 hours, corresponding to an intake of copper of 3.78 mg, 3.90 mg of zinc, 0.20 mg of manganese, 0.24 mg of cobalt, 363 mg of magnesium, 240 mg of calcium and 15 mEz of phosphates. The results show that levels of copper, zinc, magnesium and phosphates were low during parenteral alimentation. The administration of MB 147 G resulted in a significant increase in these values, without there being any evidence of accumulation.

1,1'-Methylenebis[4-[(hydroxyimino)methyl]-pyridinium] (MMB4) dimethanesulfonate (DMS) is a bisquaternary pyridinium aldoxime that reactivates acetylcholinesterase inhibited by organophosphorus nerve agent. Time courses of MMB4 concentrations in plasma were characterized following 7-day repeated intramuscular (IM) administrations of MMB4 DMS to male and female Sprague-Dawley rats, New Zealand White rabbits, beagle dogs (single dose only), and rhesus monkeys at drug dose levels used in earlier toxicology studies. In general, there were no significant differences in MMB4 toxicokinetic (TK) parameters between males and females for all the species tested in these studies. After a single IM administration to rats, rabbits, dogs, and monkeys, MMB4 DMS was rapidly absorbed, resulting in average T max values ranging from 5 to 30 minutes. Although C max values did not increase dose proportionally, the overall exposure to MMB4 in these preclinical species, as indicated by area under the curve (AUC) extrapolated to the infinity (AUC∞) values, increased in an approximately dose-proportional manner. The MMB4 DMS was extensively absorbed into the systemic circulation after IM administration as demonstrated by greater than 80% absolute bioavailability values for rats, rabbits, and dogs. Repeated administrations of MMB4 DMS for 7 days did not overtly alter TK parameters for MMB4 in rats, rabbits, and monkeys (150 and 300 mg/kg/d dose groups only). However, C max and AUC values decreased in monkeys given 450 and 600 mg/kg IM doses of MMB4 DMS following repeated administrations for 7 days. Based on the TK results obtained from the current study and published investigations, it was found that the apparent volume of distribution and clearance values were similar among various preclinical species, except for the rat.

Cranial MRI was obtained in 13 of a group of 57 children receiving long-term parenteral nutrition, who were being investigated for hypermanganasaemia. Increased signal intensity on T1-weighted images has been reported in adult patients on long-term parenteral nutrition and with encephalopathy following chronic manganese exposure in arc welding. It has been postulated that these changes are due to deposition of the paramagnetic trace element manganese. In excess manganese is hepato- and neurotoxic and we present the correlation of whole blood manganese levels with imaging findings. The age range of our patients was 6 months to 10 years, and the duration of therapy 3 months to 10 years. In 7 children we found characteristic increased signal intensity on T1-weighted images, with no abnormality on T2-weighted images. All patients had elevated whole blood manganese levels, suggesting that the basis for this abnormality is indeed deposition of manganese within the tissues. (orig.). With 3 figs

Full Text Available Disease can cause declines in wildlife populations and significantly threaten their survival. Recent expansion of human and domestic animal populations has made wildlife more susceptible to transmission of pathogens from domestic animal hosts. We conducted a pathogen surveillance and mortality survey for the population of African wild dogs (Lycaon pictus in KwaZulu-Natal (KZN, South Africa, from January 2006–February 2007. Samples were obtained from 24 wild dogs for canine distemper virus (CDV and canine parvovirus (CPV serological testing. Data were collected on the presence of CDV, CPV, and rabies virus in the KZN domestic dog (Canis familiaris population from 2004–06. The presence of these pathogens was confirmed in domestic dogs throughout KZN. Wild dogs exhibited 0% and 4.2% prevalence for CDV and CPV antibodies, respectively. In 2006 the largest wild dog pack in KZN was reduced from 26 individuals to a single animal; disease due to rabies virus was considered the most probable cause. This study provides evidence that CDV, CPV and rabies are potential threats to African wild dog conservation in KZN. The most economical and practical way to protect wild dogs from canine pathogens may be via vaccination of sympatric domestic dogs; however, such programmes are currently limited.

Parenteral treatment of episodic tension-type headache: a systematic review.

Tension-type headache is highly prevalent in the general population and is a consistent if not frequent cause of visits to acute care settings. Analgesics such as nonsteroidal anti-inflammatory drugs, acetaminophen, and salicylates are considered first-line therapy for treatment of tension-type headache. For patients who present to an acute care setting with persistent tension-type headache despite analgesic therapy, it is not clear which parenteral agent should be administered. We performed a systematic review of the medical literature to determine whether parenteral therapies other than salicylates or nonsteroidals are efficacious for acute tension-type headache. We performed a systematic review of Medline, EMBASE, CINAHL, Google scholar, and the Cochrane Central Registry of Controlled Trials from inception through August, 2012 using the search terms "tension-type headache" and "parenteral or subcutaneous or intramuscular or intravenous." Our goal was to identify randomized trials in which one parenteral treatment was compared to another active comparator or to placebo for the acute relief of tension-type headache. Parenteral was defined as intravenous, intramuscular, or subcutaneous administration. We only included studies that distinguished tension-type headache from other primary headache disorders, such as migraine. The primary outcome for this review was measures of efficacy one hour after medication administration. Data abstraction was performed by two authors. Disagreements were resolved by a third author. We assessed the internal validity of trials using the Cochrane Collaboration risk of bias tool. Because of the small number of trials identified, and the substantial heterogeneity among study design and medications, we decided that combining data and reporting summary statistics would serve no useful function. The results of individual studies are presented using Number Needed to Treat (NNT) with 95%CI when dichotomous outcomes were available and

OBJECTIVE To determine whether consumption of a single dental treat with specific mechanical properties and active ingredients would provide a 24-hour effect on dental plaque bacteria and halitosis in dogs. ANIMALS 10 dogs of various breeds from a privately owned colony that had received routine dental scaling and polishing 4 weeks before the study began. PROCEDURES Dogs were randomly assigned to receive 1 placebo or dental treat first. A 4-week washout period was provided, and then dogs received the opposite treatment. Oral plaque and breath samples were collected before and 0.5, 3, 12, and 24 hours after treat consumption. Volatile sulfur compounds (VSCs) concentration was measured in breath samples. Total aerobic, total anaerobic, Porphyromonas gulae, Prevotella intermedia-like, Tannerella forsythia, and Fusobacterium nucleatum bacterial counts (measured via bacterial culture) and total live bacterial counts, total live and dead bacterial counts, and bacterial vitality (measured via quantitative real-time PCR assay) were assessed in plaque samples. RESULTS Compared with placebo treat consumption, dental treat consumption resulted in a significant decrease in breath VSCs concentration and all plaque bacterial counts, without an effect on bacterial vitality. Effects of the dental treat versus the placebo treat persisted for 12 hours for several bacterial counts and for 24 hours for breath VSCs concentration. CONCLUSIONS AND CLINICAL RELEVANCE Although clinical benefits should be investigated in larger scale, longer-term studies, results of this study suggested that feeding the evaluated dental treat may help to decrease oral bacterial growth in dogs for 12 hours and oral malodor for 24 hours. A feeding interval of 12 hours is therefore recommended.

Preventing dog bites is an intractable problem given the complex dog bite injury environment. Desexing of dogs has the opportunity of creating a safer injury environment, given the potential links between desexing and behaviour change in dogs. A systematic review of the literature was conducted to examine the evidence for desexing of dogs to reduce dog bite risk within a population health paradigm. Medline and CAB Abstracts were searched for studies that reported data on the association of dog neuter status with the risk of dog bite. All definitions of dog bite were included and all empirical studies were included in the review, limited to those published in English. Quality appraisal and data extraction were based on the 2013 evidence-based practice and critical appraisal tool from the University of Auckland. Five out of six observational studies, from four study populations found evidence that intact dogs were associated with an increased risk of dog bite compared with desexed dogs. The effect sizes ranged across the studies and given the heterogeneity of the studies no single effect size on the association between desexing and dog bite risk could be estimated. There is consistent evidence that desexing dogs is associated with a reduced risk of dog bite, although the studies reflect association and may not be causal. Although recent publications have suggested desexing is associated with health and behavioural costs in some breeds, population level evidence supports desexed dogs having a longer lifespan, and being less likely to wander with the added benefit of reducing unwanted litters. Thus, mandatory desexing presents a possible opportunity for prevention of dog bites expanding dog bite prevention beyond an education-only approach. Published by the BMJ Publishing Group Limited.

Personality consistency in dogs: a meta-analysis.

Fratkin, Jamie L; Sinn, David L; Patall, Erika A; Gosling, Samuel D

Personality, or consistent individual differences in behavior, is well established in studies of dogs. Such consistency implies predictability of behavior, but some recent research suggests that predictability cannot be assumed. In addition, anecdotally, many dog experts believe that 'puppy tests' measuring behavior during the first year of a dog's life are not accurate indicators of subsequent adult behavior. Personality consistency in dogs is an important aspect of human-dog relationships (e.g., when selecting dogs suitable for substance-detection work or placement in a family). Here we perform the first comprehensive meta-analysis of studies reporting estimates of temporal consistency of dog personality. A thorough literature search identified 31 studies suitable for inclusion in our meta-analysis. Overall, we found evidence to suggest substantial consistency (r = 0.43). Furthermore, personality consistency was higher in older dogs, when behavioral assessment intervals were shorter, and when the measurement tool was exactly the same in both assessments. In puppies, aggression and submissiveness were the most consistent dimensions, while responsiveness to training, fearfulness, and sociability were the least consistent dimensions. In adult dogs, there were no dimension-based differences in consistency. There was no difference in personality consistency in dogs tested first as puppies and later as adults (e.g., 'puppy tests') versus dogs tested first as puppies and later again as puppies. Finally, there were no differences in consistency between working versus non-working dogs, between behavioral codings versus behavioral ratings, and between aggregate versus single measures. Implications for theory, practice, and future research are discussed.

A double-isotope single-injection method without urine collection for the estimation of glomerular filtration rate (GFR) and effective renal plasma flow (ERPF) in dogs and cats was evaluated. The GFR was determined, using 14 C-inulin and ERPF was determined, using [ 3 H]tetraethylammonium bromide. Using a modified single exponential, 1-compartment mathematical model, the renal clearance of these solutes was estimated with a plasma radioactivity disappearance curve constructed from samples collected over a 150-minute time period. In 25 dogs, GFR, ERPF, and filtration fraction were 3.55 +/- 0.14 ml/kg/min, 10.51 +/- 0.72 ml/kg/min, and 0.34 +/- 0.02, respectively. In 25 cats, GFR, ERPF, and filtration fraction were 3.24 +/- 0.14 ml/kg/min, 8.14 +/- 0.53 ml/kg/min, and 0.39 +/- 0.02, respectively. This time-efficient and reliable method, using beta-emitting isotopes, yielded renal functional values well within the normal ranges reported by a variety of other isotopic and nonisotopic procedures. The advantages of the present procedure over previous double-isotope single-injection methods include the use of less costly, lower energy-using, and less penetrating beta emittors, as well as a shortened blood sampling schedule

Ecosystem engineering varies spatially: a test of the vegetation modification paradigm for prairie dogs

Colonial, burrowing herbivores can be engineers of grassland and shrubland ecosystems worldwide. Spatial variation in landscapes suggests caution when extrapolating single-place studies of single species, but lack of data and the need to generalize often leads to ‘model system’ thinking and application of results beyond appropriate statistical inference. Generalizations about the engineering effects of prairie dogs (Cynomys sp.) developed largely from intensive study at a single complex of black-tailed prairie dogs C. ludovicianus in northern mixed prairie, but have been extrapolated to other ecoregions and prairie dog species in North America, and other colonial, burrowing herbivores. We tested the paradigm that prairie dogs decrease vegetation volume and the cover of grasses and tall shrubs, and increase bare ground and forb cover. We sampled vegetation on and off 279 colonies at 13 complexes of 3 prairie dog species widely distributed across 5 ecoregions in North America. The paradigm was generally supported at 7 black-tailed prairie dog complexes in northern mixed prairie, where vegetation volume, grass cover, and tall shrub cover were lower, and bare ground and forb cover were higher, on colonies than at paired off-colony sites. Outside the northern mixed prairie, all 3 prairie dog species consistently reduced vegetation volume, but their effects on cover of plant functional groups varied with prairie dog species and the grazing tolerance of dominant perennial grasses. White-tailed prairie dogs C. leucurus in sagebrush steppe did not reduce shrub cover, whereas black-tailed prairie dogs suppressed shrub cover at all complexes with tall shrubs in the surrounding habitat matrix. Black-tailed prairie dogs in shortgrass steppe and Gunnison's prairie dogs C. gunnisoni in Colorado Plateau grassland both had relatively minor effects on grass cover, which may reflect the dominance of grazing-tolerant shortgrasses at both complexes.

Full Text Available Abstract Background This study examines changes in socio-demographic, environmental and intrapersonal factors associated with dog acquisition in non-dog owners at baseline to 12-months follow-up and the effect of dog acquisition on minutes per week of recreational walking. Methods RESIDE study participants completed self-administered questionnaires (baseline and 12-months follow-up measuring physical activity, dog ownership, dog walking behavior as well as environmental, intrapersonal and socio-demographic factors. Analysis was restricted to 'Continuing non-owners' (i.e., non-owners at both baseline and follow-up; n = 681 and 'New dog owners' (i.e., non-owners who acquired a dog by follow-up; n = 92. Results Overall, 12% of baseline non-owners had acquired a dog at follow-up. Dog acquisition was associated with working and having children at home. Those who changed from single to couple marital status were also more likely to acquire a dog. The increase in minutes of walking for recreation within the neighborhood from baseline to follow-up was 48 minutes/week for new dog owners compared with 12 minutes/week for continuing non-owners (p p p > 0.05 after further adjustment for change in baseline to follow-up variables. Increase in intention to walk was the main factor contributing to attenuation of the effect of dog acquisition on recreational walking. Conclusion This study used a large representative sample of non-owners to examine the relationship between dog acquisition and recreational walking and provides evidence to suggest that dog acquisition leads to an increase in walking. The most likely mechanism through which dog acquisition facilitates increased physical activity is through behavioral intention via the dog's positive effect on owner's cognitive beliefs about walking, and through the provision of motivation and social support for walking. The results suggest that behavioral intention mediates the relationship between dog acquisition

Zinc: physiology, deficiency, and parenteral nutrition.

Science.gov (United States)

Livingstone, Callum

2015-06-01

The essential trace element zinc (Zn) has a large number of physiologic roles, in particular being required for growth and functioning of the immune system. Adaptive mechanisms enable the body to maintain normal total body Zn status over a wide range of intakes, but deficiency can occur because of reduced absorption or increased gastrointestinal losses. Deficiency impairs physiologic processes, leading to clinical consequences that include failure to thrive, skin rash, and impaired wound healing. Mild deficiency that is not clinically overt may still cause nonspecific consequences, such as susceptibility to infection and poor growth. The plasma Zn concentration has poor sensitivity and specificity as a test of deficiency. Consequently, diagnosis of deficiency requires a combination of clinical assessment and biochemical tests. Patients receiving parenteral nutrition (PN) are susceptible to Zn deficiency and its consequences. Nutrition support teams should have a strategy for assessing Zn status and optimizing this by appropriate supplementation. Nutrition guidelines recommend generous Zn provision from the start of PN. This review covers the physiology of Zn, the consequences of its deficiency, and the assessment of its status, before discussing its role in PN. © 2015 American Society for Parenteral and Enteral Nutrition.

A novel spot-on formulation combining fipronil, amitraz and (S)-methoprene (CERTIFECT™, Merial Limited, GA, USA) was evaluated in adult Beagle dogs in a study to determine its adulticidal efficacy against the dog flea (Ctenocephalides canis, Curtis, 1826). Sixteen dogs were randomly allocated to treatment groups: 8 dogs served as untreated controls, and 8 dogs were treated once. Treatment consisted of applying a new combination formulation to deliver at least 6.7mg fipronil/kg body weight (bw), 8.0mg amitraz/kg bw, and 6.0mg (S)-methoprene/kg bw. The combination was designed to enhance the efficacy against ticks of the original fipronil/(S)-methoprene combination. Each dog was infested with 100 adult unfed dog fleas within 24h prior to treatment and then at weekly intervals for 8 weeks after treatment. At 24h after treatment or after each subsequent infestation, each dog was combed thoroughly to remove live fleas to be counted. A single treatment with CERTIFECT provided excellent knock-down of fleas within 24h after treatment and controlled re-infestations for up to 7 weeks (efficacy ≥96.5%, p<0.05).

Beagle dogs given a single inhalation exposure to 239 Pu(NO 3 ) 4 , and observed for life-span dose-effect relationship, died from radiation pneumonitis (four of five at the highest dosage level, in 14 to 25 mo postexposure; 1 of 20 at the medium-high dosage level, at 34 mo postexposure). There were also indications in these dogs of radiation osteosis, characterized by peritrabecular fibrosis. One dog, at 39 mo postexposure, has radiographic evidence of an osteosarcoma. Leukopenia, lymphopenia, neutropenia and decreased numbers of circulating monocytes and eosinophils occurred at the two highest dosage levels, as previously reported (Annual Report, 1978). Twelve dogs given a single inhalation exposure to 238 Pu(NO 3 ) 4 showed a more rapid translocation of 238 Pu(NO 3 ) 4 to bone and liver than was observed for 239 Pu(NO 3 ) 4 , but at 1 yr postexposure the percentage of the final body burden in bone and liver were similar for the two isotopes

Miniature Schnauzer dogs are predisposed to idiopathic hypertriglyerceridemia, which increases risk for diseases such as pancreatitis and gallbladder mucocele. Recently, elevated triglyceride concentrations have been associated with proteinuria in this breed, although it is difficult to determine which abnormality is primary. Retrospective review of renal tissue from 27 proteinuric Miniature Schnauzers revealed that 20 dogs had ultrastructural evidence of osmophilic globules consistent with lipid in glomerular tufts. Seven of these dogs had lipid thromboemboli in glomerular capillary loops that distorted their shape and compressed circulating erythrocytes. Triglyceride concentrations were reported in 6 of these 7 dogs, and all were hypertriglyceridemic. In addition, glomerular lipidosis (defined as accumulation of foam cells within peripheral capillary loops) was identified in a single dog. The remaining 12 dogs had smaller amounts of lipid that could only be identified ultrastructurally. Neither signalment data nor clinicopathologic parameters (serum albumin, serum creatinine, urine protein-to-creatinine ratio, and blood pressure) differed among the various types of lipid lesions. During the time course of this study, all dogs diagnosed with glomerular lipid thromboemboli were Miniature Schnauzers, underscoring the importance of recognizing these clear spaces within capillary loops as lipid.

Patients dependent on parenteral nutrition (PN) are among a group at risk of developing iodine deficiency. Supplementation with iodine in this population has been debated in a number of studies, resulting in variable clinical practices. The Committee on Clinical Practice Issues of the American Society for Clinical Nutrition recommends a dose of 1 mcg/kg/d of parenteral iodine for patients receiving PN. At our institution, PN trace elements do not include iodine, although this is not the case internationally. Our study sought to assess iodine levels and thyroid function in a cohort of PN-dependent pediatric patients. A retrospective analysis studied 32 pediatric patients with a variety of medical diagnoses who received PN as a primary means of nutrition for 6 months or longer. Patients received variable proportions of their total caloric intake as PN, which ranged from 14%-100%. Iodine and thyroid function levels were obtained by serum sampling. No patient in our cohort of 32 demonstrated thyroid dysfunction or developed iodine deficiency. The length of time on PN and the percentage of total nutrition intake as PN were not associated with iodine levels (P Parenteral and Enteral Nutrition.

Parenteral and oral antibiotic duration for treatment of pediatric osteomyelitis: a systematic review protocol

Science.gov (United States)

2013-01-01

Background Pediatric osteomyelitis is a bacterial infection of bones requiring prolonged antibiotic treatment using parenteral followed by enteral agents. Major complications of pediatric osteomyelitis include transition to chronic osteomyelitis, formation of subperiosteal abscesses, extension of infection into the joint, and permanent bony deformity or limb shortening. Historically, osteomyelitis has been treated with long durations of antibiotics to avoid these complications. However, with improvements in management and antibiotic treatment, standard of care is moving towards short durations of intravenous antibiotics prior to enteral antibiotics. Methods/Design The authors will perform a systematic review based on PRISMA guidelines in order to evaluate the literature, looking for evidence to support the optimal duration of parenteral and enteral therapy. The main goals are to see if literature supports shorter durations of either parenteral antibiotics and/or enteral antibiotics. Multiple databases will be investigated using a thorough search strategy. Databases include Medline, Cochrane, EMBASE, SCOPUS, Dissertation Abstracts, CINAHL, Web of Science, African Index Medicus and LILACS. Search stream will include medical subject heading for pediatric patients with osteomyelitis and antibiotic therapy. We will search for published or unpublished randomized and quasi-randomized controlled trials. Two authors will independently select articles, extract data and assess risk of bias by standard Cochrane methodologies. We will analyze comparisons between dichotomous outcomes using risk ratios and continuous outcomes using mean differences. 95% confidence intervals will be computed. Discussion One of the major dilemmas of management of this disease is the duration of parenteral therapy. Long parenteral therapy has increased risk of serious complications and the necessity for long therapy has been called into question. Our study aims to review the currently available

This work aims to provide staff accreditation methodology to harmonize and secure practices for parenteral nutrition bags preparation. The methodology used in the present study is inspired from project management and quality approach. Existing training supports were used to produce accreditation procedure and evaluation supports. We first defined abilities levels, from level 1, corresponding to accredited learning agent to level 3, corresponding to expert accredited agent. Elements assessed for accreditation are: clothing assessment either by practices audit or by microbiologic test, test bags preparation and handling assessment, bag production to assess aseptic filling for both manual or automatized method, practices audit, number of days of production, and non-conformity following. At Angers Hospital, in 2014, production staff is composed of 12 agents. Staff accreditation reveals that 2 agents achieve level 3, 8 agents achieve level 2 and 2 agents are level 1. We noted that non-conformity decreased as accreditation took place from 81 in 2009 to 0 in 2014. To date, there is no incident due to parenteral bag produced by Angers hospital for neonatal resuscitation children. Such a consistent study is essential to insure a secured nutrition parenteral production. This also provides a satisfying quality care for patients. Copyright © 2016 Académie Nationale de Pharmacie.

2015-01-01

Parenteral nutrition-associated liver disease (PNALD) is a particularly important problem in patients who need this type of nutritional support for a long time. Prevalence of the condition is highly variable depending on the series, and its clinical presentation is different in adults and children. The etiology of PNALD is not well defined, and participation of several factors at the same time has been suggested. When a bilirubin level >2 mg/dl is detected for a long time, other causes of liver disease should be ruled out and risk factors should be minimized. The composition of lipid emulsions used in parenteral nutrition is one of the factors related to PNALD. This article reviews the different types of lipid emulsions and the potential benefits of emulsions enriched with omega-3 fatty acids. Copyright © 2014 SEEN. Published by Elsevier España, S.L.U.

The effect of total parenteral nutrition on nutrients absorption and glycoprotein changes of brush border membrane was examined in rat small intestine. In total parenteral nutrition rats, a marked decrease in activity of brush border enzymes was observed mainly in the proximal and middle segments of the intestine. Galactose perfusion of jejunal segment showed that hexose absorption was significantly inhibited, while intestinal absorption of glycine or dipeptide, glycylglycine was not significantly affected by total parenteral nutrition treatment. When brush border membrane glycoprotein profile was examined by [3H]-glucosamine or [3H]-fucose incorporation into jejunal loops, significant changes were observed in the glycoprotein pattern of brush border membrane especially in the high molecular weight range over 120 kDa after total parenteral nutrition treatment, suggesting strong dependency of glycoprotein synthesis on luminal substances. Molecular weight of sucrase isomaltase in brush border membrane detected by specific antibody showed no significant difference, however, in total parenteral nutrition and control rats. Also, molecular weight of specific sodium glucose cotransporter of intestinal brush border membrane detected by selective photoaffinity labelling was not altered in total parenteral nutrition rats. It may be that prolonged absence of oral food intake may produce significant biochemical changes in brush border membrane glycoprotein and absorptive capacity of small intestine, but these changes were not observed in all brush border membrane glycoproteins.

Patients with end-stage cancer and advanced chronic bowel disease are often malnourished, which has a negative effect on patients' outcome, well-being, and activity. It is inconclusive whether these patients benefit from home parenteral nutrition. This prospective exploratory study investigates its influence on nutrition state, muscle strength, mobility, and quality of life. Patients ≥18 years old with an indication for home parenteral nutrition were included and followed for 2-24 months. Nutrition parameters, activity, and quality of life were assessed. Forty-eight patients participated (mean age 11.5 years), and 85% were severely malnourished (subjective global assessment score, class C). Four weeks after parenteral nutrition, patients with tumors demonstrated a deterioration in phase angle (from 3.9 to 3.4) and extracellular mass:body cell mass ratio (from 1.6 to 2.1), while patients with bowel disease improved (from 3.4 to 4.0 and 2.1 to 1.6, respectively); grip strength remained constant in both groups (difference: 1.11 and -2.11, respectively). Activity improved in patients with bowel disease but stayed the same in the tumor group (P = .02 and P = .33, respectively). When the groups were pooled, emotional and social functioning domain scores (P parenteral nutrition. Both groups seem to benefit from home parenteral nutrition without harmful side effects.

Vitamin E in new-generation lipid emulsions protects against parenteral nutrition-associated liver disease in parenteral nutrition-fed preterm pigs

Science.gov (United States)

Parenteral nutrition (PN) in preterm infants leads to PN-associated liver disease (PNALD). PNALD has been linked to serum accumulation of phytosterols that are abundant in plant oil but absent in fish oil emulsions. Whether modifying the phytosterol and vitamin E composition of soy and fish oil lipi...

Standardised neonatal parenteral nutrition formulations – an Australasian group consensus 2012

Science.gov (United States)

2014-01-01

Standardised parenteral nutrition formulations are routinely used in the neonatal intensive care units in Australia and New Zealand. In 2010, a multidisciplinary group was formed to achieve a consensus on the formulations acceptable to majority of the neonatal intensive care units. Literature review was undertaken for each nutrient and recommendations were developed in a series of meetings held between November 2010 and April 2011. Three standard and 2 optional amino acid/dextrose formulations and one lipid emulsion were agreed by majority participants in the consensus. This has a potential to standardise neonatal parenteral nutrition guidelines, reduce costs and prescription errors. PMID:24548745

[When enteral nutrition is not possible in intensive care patients: whether to wait or use parenteral nutrition?

- Overfeeding of critically ill patients is associated with a higher incidence of infections and an increased length of ventilation. However, trophic nutrition or permissive underfeeding appears to have no negative effect on the patient and may even provide a survival benefit.- Initiation of enteral nutrition within 24-48 hours after Intensive Care Unit (ICU) admission may reduce the number of complications and increase the chance of survival.- Total parenteral nutrition is associated with a higher risk of infections than enteral nutrition. This seems to be related to the higher calorie intake with parenteral nutrition rather than the route of administration.- In previously well-nourished patients, in whom enteral nutrition is only partially successful, it is safe to wait for up to 8 days before initiating supplemental parenteral nutrition.- In critically ill children, it is also safe to start supplemental parenteral nutrition at a late (on the 8th day after admission) rather than an early stage (within 24 hours of admission). Late supplemental parenteral nutrition may even result in fewer infectious complications and shorter hospitalisation.

Parenteral nutrition (PN), a lifesaving therapy in patients with intestinal failure, has been associated with hepatobiliary complications including steatosis, cholestasis and fibrosis, collectively known as parenteral nutrition-associated liver disease (PNALD). To date, the pathogenesis of PNALD is poorly understood and therapeutic options are limited. Impaired bile salt homeostasis has been proposed to contribute PNALD. The objective of this study was to establish a PNALD model in rats and to evaluate the effects of continuous parenteral nutrition (PN) on bile salt homeostasis. Rats received either PN via the jugular vein or received normal diet for 3, 7 or 14 days. Serum biochemistry, hepatic triglycerides, circulating bile salts and C4, IL-6 and TNF-alpha, and lipogenic and bile salt homeostatic gene expression in liver and ileum were assessed. PN increased hepatic triglycerides already after 3 days of administration, and resulted in conjugated bilirubin elevation after 7 or more days. This indicates PN-induced steatosis and impaired canalicular secretion of bilirubin, the latter which is in line with reduced hepatic expression of Mrp2 mRNA. There was no histological evidence for liver inflammation after PN administration, and circulating levels of pro-inflammatory cytokines IL-6 and TNF-α, were comparable in all groups. Hepatic expression of Fxr mRNA was decreased after 7 days of PN, without apparent effect on expression of Fxr targets Bsep and Shp. Nonetheless, Cyp7a1 expression was reduced after 7 days of PN, indicative for lowered bile salt synthesis. Circulating levels of C4 (marker of bile salt synthesis) were also decreased after 3, 7 and 14 days of PN. Levels of circulating bile salts were not affected by PN. This study showed that PN in rats caused early mild steatosis and cholestasis, while hepatic and systemic inflammation were not present. The onset of these abnormalities was associated with alterations in bile salt synthesis and transport. This

Single-Nucleotide-Polymorphism-Based Association Mapping of Dog Stereotypes

Phenotypic stereotypes are traits, often polygenic, that have been stringently selected to conform to specific criteria. In dogs, Canis familiaris, stereotypes result from breed standards set for conformation, performance (behaviors), etc. As a consequence, phenotypic values measured on a few individuals are representative of the breed stereotype. We used DNA samples isolated from 148 dog breeds to associate SNP markers with breed stereotypes. Using size as a trait to test the method, we identified six significant quantitative trait loci (QTL) on five chromosomes that include candidate genes appropriate to regulation of size (e.g., IGF1, IGF2BP2 SMAD2, etc.). Analysis of other morphological stereotypes, also under extreme selection, identified many additional significant loci. Less well-documented data for behavioral stereotypes tentatively identified loci for herding, pointing, boldness, and trainability. Four significant loci were identified for longevity, a breed characteristic not under direct selection, but inversely correlated with breed size. The strengths and limitations of the approach are discussed as well as its potential to identify loci regulating the within-breed incidence of specific polygenic diseases. PMID:18505865

As service dogs, emotional support dogs, and therapy dogs have become more prevalent in the USA, so too has the controversy surrounding their legitimacy. Yet, there is a lack of objective data regarding the public's understanding of the role played by each of these types of animals, as well as their perceptions regarding the legitimacy of their integration. An anonymous, online survey was distributed to examine the perceptions of US adults who do not own any type of assistance animal. A total of 505 individuals responded to the online survey, yielding 284 usable responses. Results suggest widespread misconceptions about definitions, rules, regulations, and rights associated with each type of assistance dog. In general, service dogs are more likely to be perceived as helping with a legitimate need, and their access to public spaces is viewed favorably. While there are some concerns about the legitimacy and necessary access rights for emotional support dogs, members of the public correctly identified the roles and rights of therapy dogs. Despite the media's focus on abuses and false representation of these dogs, most participants reported feeling the majority of people are not taking advantage of the system.

Why do adult dogs 'play'?

Science.gov (United States)

Bradshaw, John W S; Pullen, Anne J; Rooney, Nicola J

2015-01-01

Among the Carnivora, play behaviour is usually made up of motor patterns characteristic of predatory, agonistic and courtship behaviour. Domestic dogs are unusual in that play is routinely performed by adults, both socially, with conspecifics and with humans, and also asocially, with objects. This enhanced playfulness is commonly thought to be a side effect of paedomorphosis, the perpetuation of juvenile traits into adulthood, but here we suggest that the functions of the different types of play are sufficiently distinct that they are unlikely to have arisen through a single evolutionary mechanism. Solitary play with objects appears to be derived from predatory behaviour: preferred toys are those that can be dismembered, and a complex habituation-like feedback system inhibits play with objects that are resistant to alteration. Intraspecific social play is structurally different from interspecific play and may therefore be motivationally distinct and serve different goals; for example, dogs often compete over objects when playing with other dogs, but are usually more cooperative when the play partner is human. The majority of dogs do not seem to regard competitive games played with a human partner as "dominance" contests: rather, winning possession of objects during games appears to be simply rewarding. Play may be an important factor in sociality, since dogs are capable of extracting social information not only from games in which they participate, but also from games that they observe between third parties. We suggest that the domestic dog's characteristic playfulness in social contexts is an adaptive trait, selected during domestication to facilitate both training for specific purposes, and the formation of emotionally-based bonds between dog and owner. Play frequency and form may therefore be an indicator of the quality of dog-owner relationships. Copyright © 2014 Elsevier B.V. All rights reserved.

A Review of the Parenteral Nutrition Supply Service in an Irish Neonatal Unit

LENUS (Irish Health Repository)

Smith, A

2018-06-01

Neonatal Intensive Care (NICU) patients have individual nutritional requirements often requiring Patient Specific Parenteral Nutrition (PSPN). From October 2015, the national PSPN compounding service availability changed from 7 days per week service to 5 days per week (i.e. no weekend and limited bank holiday ordering available). The aim of this study was to examine the introduction of a 5 day only PSPN supply on neonatal patient parenteral nutrition availability in a tertiary NICU.

This project is concerned with long-term experiments to determine the lifespan dose-effect relationships of inhaled 239 PuO 2 and 238 PuO 2 in beagles. Beagle dogs given a single exposure to 239 PuO 2 or 238 PuO 2 aerosols are being observed for lifespan dose-effect relationships. The 239 Pu body burden of the nine dogs that died of pulmonary-fibrosis-induced respiratory insufficiency during the first 3 yr after exposure was 1 to 12μCi. Nineteen of the dogs exposed to 238 Pu haved died during the first 7-1/2 yr after exposure due to bone and/or lung tumors; their body burdens at death ranged from 0.7 to 10μCi. Chronic lymphopenia was the earliest observed effect after inhalation of 239 PuO 2 or 238 PuO 2

This study analyzed intestinal anastomoses by manual suture and by compression with biofragmentable ring under delay of cicatrization administering parenteral corticoids. Twenty dogs were divided into two groups: control and test, the latter submitted to intramuscular administration of hydrocortisone hemisuccinate, 25 to 33 mg/kg/day, on the 30th preoperative and 7th postoperative days. During surgery, each animal underwent two colon sections with anastomosis by manual suture in a single extramucous plane and compression with biofragmentable ring. The animals were sacrificed 7 days after the procedure to evaluate the anastomoses. In the postoperative period, one death occurred in the test group and two in the control group, caused by nonblocked fistula in the anastomoses by ring compression. Statistically, there was a similar incidence of adherences, fistulas, afferent dilatation and obstruction using comparison methods. On microscopy, deficiency in mucous regeneration of the anastomoses by compression was observed. Computerized histological analysis evidenced in the anastomoses by compression, a greater inflammatory reaction, greater edema of the submucous membrane and enlarged scars. It was concluded that, with the biofragmentable ring, in colonic anastomosis under delay of cicatrization induced by corticoids, similar results to manual suture regarding to postoperative complications incidence were obtained; ring, however, determined worse mucous regeneration and greater cicatricial inflammatory reaction.

Diarrhea is one of the most common clinical symptoms reported in companion animal clinics. Dog circovirus (DogCV) is a new mammalian circovirus that is considered to be a cause of alimentary syndromes such as diarrhea, vomiting and hemorrhagic enteritis. DogCV has previously only been identified in the United States, Italy, Germany (GeneBank accession number: KF887949) and China (GeneBank accession number: KT946839). Therefore, the aims of this study were to determine the prevalence of DogCV in Taiwan and to explore the correlation between diarrhea and DogCV infection. Clinical specimens were collected between 2012 and 2014 from 207 dogs suffering from diarrhea and 160 healthy dogs. In this study, we developed a sensitive and specific SYBR Green-based real-time PCR assays to detected DogCV in naturally infected animals. Of the analyzed fecal samples from diarrheal dogs and health dogs, 58 (28.0 %) and 19 (11.9 %), respectively, were DogCV positive. The difference in DogCV prevalence was highly significant (P = 0.0002755) in diarrheal dogs. This is the first study to reveal that DogCV is currently circulating in domestic dogs in Taiwan and to demonstrate its high detection rate in dogs with diarrhea.

To report use of thoracoscopic lung lobectomy (TLL) for treatment of lung tumors (LT) in dogs. Retrospective study. Nine dogs. Dogs that had TLL for tumor removal were included. Using general anesthesia and 1-lung ventilation, TLL was performed using a 30-60 mm endoscopic gastrointestinal anastomosis stapler. If the visual field was obscured, lobe resection was completed via thoracotomy. Metastatic and primary LT were resected by thoracoscopic lobectomy in 9 dogs (6 male, 3 female; mean (+/-SD) weight, 29+/-7 kg; mean age, 10.7+/-1.9 years). Six dogs had a solitary mass and 3 dogs had 2 masses within a single lobe. The left caudal lobe was removed in 3 dogs. In 5 dogs, TLL was used alone whereas conversion to thoracotomy was required in 4 dogs because of poor visibility. There were 7 metastatic LT and 2 primary LT. Mean duration of thoracoscopic surgery was 108.8+/-30.3 minutes compared with 150.75+/-55.4 minutes in dogs requiring conversion to thoracotomy. Mean hospitalization was 3.1+/-1.3 days. Provided the visual field is not obscured, TLL can be performed effectively in dogs. Dogs with metastatic or primary LTs should be considered for TLL, particularly for small masses positioned away from the hilus in the left caudal lung lobe.

Sick newborn and preterm infants frequently are not able to be fed enterally, necessitating parenteral fluid and nutrition. Potential benefits of higher parenteral amino acid (AA) intake for improved nitrogen balance, growth, and infant health may be outweighed by the infant's ability to utilise high intake of parenteral AA, especially in the days after birth. The primary objective is to determine whether higher versus lower intake of parenteral AA is associated with improved growth and disability-free survival in newborn infants receiving parenteral nutrition.Secondary objectives include determining whether:• higher versus lower starting or initial intake of amino acids is associated with improved growth and disability-free survival without side effects;• higher versus lower intake of amino acids at maximal intake is associated with improved growth and disability-free survival without side effects; and• increased amino acid intake should replace non-protein energy intake (glucose and lipid), should be added to non-protein energy intake, or should be provided simultaneously with non-protein energy intake.We conducted subgroup analyses to look for any differences in the effects of higher versus lower intake of amino acids according to gestational age, birth weight, age at commencement, and condition of the infant, or concomitant increases in fluid intake. We used the standard search strategy of the Cochrane Neonatal Review Group to search the Cochrane Central Register of Controlled Trials (2 June 2017), MEDLINE (1966 to 2 June 2017), Embase (1980 to 2 June 2017), and the Cumulative Index to Nursing and Allied Health Literature (CINAHL) (1982 to 2 June 2017). We also searched clinical trials databases, conference proceedings, and citations of articles. Randomised controlled trials of higher versus lower intake of AAs as parenteral nutrition in newborn infants.

A life-span study was conducted in 128 beagle dogs to determine the biological effects of intravenously injected 224 Ra chloride. The 224 Ra chloride was prepared by the same method used for intravenous injections in humans who were treated for ankylosing spondylitis and tuberculosis. Thus the results obtained from dogs can be compared directly to the population of treated humans, both for the elucidation of the effect of exposure rate and for comparison with other radionuclides for which data for humans are unavailable. Using equal numbers of males and females, the dogs were injected with one of four levels of 224 Ra resulting in initial body burdens of approximately 13, 40, 120 or 350 kBq of 224 Ra kg -1 body mass. A control group of dogs was injected with diluent only. All dogs were divided further into three groups for which the amount of injected 224 Ra (half-life of 3.62 days) or diluent was given in a single injection or divided equally into 10 or 50 weekly injections. As a result of these three injection schedules, the accumulation of dose from the injected 224 Ra was distributed over approximately 1, 3 or 12 months. Each injection schedule included four different injection levels resulting in average absorbed α-particle doses to bone of 0.1, 0.3, 1 and 3 Gy, respectively. The primary early effect observed was a hematological dyscrasia in the dogs receiving either of the two highest injection levels. The effect was most severe in the dogs receiving a single injection of 224 Ra and resulted in the death of three dogs injected at the highest level. The late-occurring biological effects were tumors. Bone tumors were the most common followed by tumors in the nasal mucosa. 52 refs., 8 figs., 8 tabs

Patients receiving long-term parenteral nutrition (PN) are at increased risk of aluminium (Al) toxicity because of bypass of the gastrointestinal tract during PN infusion. Complications of Al toxicity include metabolic bone disease (MBD), Al-associated encephalopathy in adults, and impaired neurological development in preterm infants. Unlike the United States, there are no regulations regarding Al content of large- and small-volume parenterals in Canada. We, therefore, aimed to present our data on plasma Al concentration and Al intake from our cohort of pediatric patients receiving long-term PN. Plasma Al concentration was retrospectively gathered from the patient charts of all 27 patients with intestinal failure (IF) receiving long-term PN at The Hospital for Sick Children, Toronto, Canada, and compared with age- and sex-matched controls recruited for comparison. In addition, Al concentration was measured in PN samples collected from 10 randomly selected patients with IF and used to determine their Al intake. The plasma Al concentration of patients with IF receiving long-term PN was significantly higher than that of control participants (1195 ± 710 vs 142 ± 63 nmol/L; P Parenteral and Enteral Nutrition.

Parenteral Nutrition-Associated Liver Disease: The Role of the Gut Microbiota.

Parenteral nutrition (PN) provides life-saving nutritional support in situations where caloric supply via the enteral route cannot cover the necessary needs of the organism. However, it does have serious adverse effects, including parenteral nutrition-associated liver disease (PNALD). The development of liver injury associated with PN is multifactorial, including non-specific intestine inflammation, compromised intestinal permeability, and barrier function associated with increased bacterial translocation, primary and secondary cholangitis, cholelithiasis, short bowel syndrome, disturbance of hepatobiliary circulation, lack of enteral nutrition, shortage of some nutrients (proteins, essential fatty acids, choline, glycine, taurine, carnitine, etc.), and toxicity of components within the nutrition mixture itself (glucose, phytosterols, manganese, aluminium, etc.). Recently, an increasing number of studies have provided evidence that some of these factors are directly or indirectly associated with microbial dysbiosis in the intestine. In this review, we focus on PN-induced changes in the taxonomic and functional composition of the microbiome. We also discuss immune cell and microbial crosstalk during parenteral nutrition, and the implications for the onset and progression of PNALD. Finally, we provide an overview of recent advances in the therapeutic utilisation of pro- and prebiotics for the mitigation of PN-associated liver complications.

Pet dogs and cats in the USA are commonly exposed to potentially hazardous substances found in domestic environments. Requests for assistance and advice received by the Kansas State Veterinary Diagnostic Laboratory regarding exposures in dogs and cats to substances perceived by their caretakers to be potentially harmful included 1,616 phone calls, over a 3-year period covering 2009-2012. Enquiries occurred more often during summer. Dogs were involved in 84.7 % of calls and cats in 15.3 %. Oral exposures were reported in 95.5 % of calls, dermal exposures in 3.7 % of calls, inhalation exposures in 0.6 % of calls, and parenteral exposures in 0.2 % of calls. Therapeutic drugs were the most frequently reported substances, accounting for 35.4 % of calls, followed by household chemicals (15.5 %); foods (14.8 %); pesticides (13.9 %); plants (12 %), industrial chemicals and fertilizers (3.6 %); cosmetics and personal care products (2.8 %); and animal, insect, and microorganism toxins (2.1 %). Although requests for information or assistance are not a measure of poisoning incidence, it can provide insight regarding relative exposure rates, help to identify changing exposure trends and emerging exposures, and reflect the public concern regarding actual or apparent harmful exposures in pets.

Abstract In the late 1980s an HIV-1 epidemic emerged in Romania that was dominated by subtype F1. The main route of infection is believed to be parenteral transmission in children. We sequenced partial pol coding regions of 70 subtype F1 samples from children and adolescents from the PENTA-EPPICC network of which 67 were from Romania. Phylogenetic reconstruction using the sequences and other publically available global subtype F sequences showed that 79% of Romanian F1 sequences formed a statistically robust monophyletic cluster. The monophyletic cluster was epidemiologically linked to parenteral transmission in children. Coalescent-based analysis dated the origins of the parenteral epidemic to 1983 [1981–1987; 95% HPD]. The analysis also shows that the epidemic's effective population size has remained fairly constant since the early 1990s suggesting limited onward spread of the virus within the population. Furthermore, phylogeographic analysis suggests that the root location of the parenteral epidemic was Bucharest. PMID:22251065

A 6-year-old speyed female Bull Arab-cross dog was found to have a small tonsillar nodule. Histological examination revealed a well-differentiated mast cell tumour (MCT). At initial staging, no evidence of concurrent cutaneous or visceral MCTs was found on a complete blood count, a single lateral thoracic radiograph, abdominal ultrasound or cytology of the spleen and regional lymph nodes. A diagnosis of primary tonsillar MCT was made. At 40 months postoperatively, the dog is alive with no evidence of gross tumour progression, in contrast to some previous reports of rapid disease progression and metastasis in dogs with primary oral MCTs. To the authors' knowledge, no previous reports of a primary MCT of the tonsil in dogs exist in the veterinary literature. © 2018 Australian Veterinary Association.

Three groups of healthy dogs with low antibody titers to Bordetella bronchiseptica (Bb), canine parainfluenza virus (CPI), and canine adenovirus type 2 (CAV-2) were used in this study. One group was vaccinated with a single dose of monovalent attenuated Bb vaccine and one group with a trivalent vaccine containing attenuated Bb, CPI, and CAV-2; dogs were vaccinated intranasally with a single dose of the respective vaccines. The third group served as unvaccinated controls. All vaccinated dogs subsequently developed serum antibody titers to Bb that persisted for at least 1 year. Following Bb challenge 1 year after vaccination, all vaccinated dogs, regardless of group, showed significantly fewer clinical signs and shed significantly fewer challenge organisms than unvaccinated controls. These results demonstrate that intranasal administration of a single dose of monovalent attenuated Bb vaccine or trivalent vaccine containing attenuated Bb, CPI, and CAV-2 provides 1 year of protection against Bb.

1985-01-01

To study the lifetime effects of irradiation during development, 1680 beagle dogs were given single, whole body exposures to 60Co gamma radiation at one of 6 pre- or postnatal ages. Four groups of 120 dogs each (480 or 29%) received 0.16 or 0.83 Gy at early prenatal times, 8 or 28 days postcoitus (dpc). Four groups of 120 dogs each (29%) received 0.16 or 0.83 Gy in the perinatal period at 55 dpc or 2 days postpartum (dpp). Groups of 120 and 240 dogs (21%) received 0.83 Gy at later postnatal times, 70 or 365 dpp, respectively. A group of 360 dogs (21%) were sham-irradiated. The youngest dogs are now 12 years old. Through 4 years of age, 20 dogs had neoplasms diagnosed. Five malignancies and one benign tumor were seen in the first two years, including the only fatal malignancies which occurred in 4 perinatally irradiated dogs. Up to two years of age, the other non-fatal malignancy and benign tumor were found in dogs irradiated at 365 dpp and 55 dpc. The remaining 14 neoplasms, 12 benign and 2 non-fatal malignant, were diagnosed between two and four years of age. Respective numbers of these benign and non-fatal malignant tumors found in control, perinatally irradiated, and all other irradiated dogs were 2 and 0; 5 and 1; and 5 and 1. Eight of the benign lesions were minute papillomas of the eyelids which were more frequent in the perinatally irradiated dogs. Overall, 71% (5 of 7) of the malignancies seen in the first four years of life occurred in the 29% of the dogs irradiated in the perinatal period. Sixty-seven percent (8 of 12) of all neoplasms, excluding eyelid papillomas, also occurred in perinatally irradiated dogs. These data suggest an increased risk for neoplasia after perinatal irradiation

Young adult Beagle dogs were exposed once to aerosols containing 90 SrCl 2 to obtain initial body burdens ranging from 2.5 to 250 uCi 90 Sr/kg body weight and subsequently observed throughout their life span. All of the dogs are now dead. The primary cause of death over the entire length of the study was radiation-induced osteosarcomas. However, six dogs died at less than 30 days after exposure as a result of a radiation-induced bone marrow aplasia. Review of hematological parameters of all dogs showed a similar, consistent, and often dramatic pancytopenia in those animals having a long-term retained burden of greater than 10 uCi 90 Sr/kg. The hematologic changes were similar to those seen in people exposed to high doses of whole body external radiation. 4 references, 1 figure, 1 table

African wild dogs (Lycaon pictus) are described as highly collaborative endurance pursuit hunters based on observations derived primarily from the grass plains of East Africa. However, the remaining population of this endangered species mainly occupies mixed woodland savannah where hunting strategies appear to differ from those previously described. We used high-resolution GPS and inertial technology to record fine-scale movement of all members of a single pack of six adult African wild dogs in northern Botswana. The dogs used multiple short-distance hunting attempts with a low individual kill rate (15.5%), but high group feeding rate due to the sharing of prey. Use of high-level cooperative chase strategies (coordination and collaboration) was not recorded. In the mixed woodland habitats typical of their current range, simultaneous, opportunistic, short-distance chasing by dogs pursuing multiple prey (rather than long collaborative pursuits of single prey by multiple individuals) could be the key to their relative success in these habitats.

Parenteral nutrition constitutes a life-saving therapeutic tool in patients unable to ingest/absorb oral or enteral delivered nutrients. Liver function tests abnormalities are a common therapy-related complication, thus configuring the so-called Parenteral Nutrition Associated Liver Disease (PNALD) or cholestasis (PNAC). Although the damage is frequently mild, and resolves after discontinuation of parenteral nutrition, in some cases it progresses into cirrhotic changes, especially in neonates and infants. We present a literature review focusing on the pathogenetic mechanisms-driven prevention and therapies for the cases where parenteral nutrition cannot be discontinued. Ursodeoxycholic acid has been proposed in patients with cholestatic hepatopathy, but its efficacy needs to be better established. Little evidence is available on efficacy of anti-oxidants, antibiotics, probiotics and anti TNFα. Lipid emulsions based on fish oil with a high content of long-chain polyunsaturated fatty acids ω-3 appear effective both in decreasing intrahepatic inflammation and in improving biliary flow. Most recent promising variations such as soybean/MCT/olive/fish oil emulsion [third generation lipid emulsion (SMOFlipid)] are under investigation. In conclusion, we remark the emergence of a number of novel pathomechanisms underlying the severe liver impairment damage (PNALD and PNAC) in patients treated with parenteral nutrition. Only few traditional and innovative therapeutic strategies have hitherto been shown promising. Copyright © 2015 Editrice Gastroenterologica Italiana S.r.l. Published by Elsevier Ltd.

Background: Essential fatty acid (EFA) requirements of patients receiving home parenteral nutrition (HPN) are uncertain. Objective: The objective was to evaluate the influence of the route of administration (enteral compared with parenteral) on plasma phospholipid EFA concentrations. Design......: Intestinal absorption, parenteral supplement of EFAs, and plasma phospholipid EFA concentrations were investigated in balance studies in 4 groups (A, B, C, and D) of 10 patients with short-bowel syndrome and a fecal loss of >2000 kJ/d. Groups A (fat malabsorption 50%) did...... absorption was negligible in groups C and D. Thus, intestinal absorption of EFAs in group A. corresponded to parenteral EFA supplements in group C, whereas group D was almost totally deprived of EFAs. The median plasma phospholipid concentration of linoleic acid decreased by 21.9%, > 16.3%, >13.8%, 11...

Full Text Available Background: Pemphigus vulgaris is associated with high morbidity as well as significant mortality rate. Today the risk of death in pemphigus from the side effect of oral prednisolone is greater than risk of death from the disease itself. Objec­tive: To observe the adverse effects of parenteral dexamethasone compared with oral prednisolone in the treatment of pemphigus vulgaris. Methods: An interventional study was carried out in the department of Dermatology and Venereol­ogy, Bangabandu Sheikh Mujib Medical University, Dhaka, Bangladesh. Total number of patients was thirty and among them fifteen patients were treated with parenteral dexamethasone (Group-A and other fifteen were treated with oral prednisolone (Group-B. Results: The study showed statistically significant differences of skin lesion as well as mucosal lesion of pemphigus after 6 weeks of therapy between of two groups (P<0.05. The most common adverse effects were increased body weight(40%, increased appetite(40%, and puffy face(40% in dexamethasone group. In prednisolone group, these side effects were 60% of the subjects. Other side effects in dexamethasone group were hyperglycemia (33.33%, hypertension (26.66%, and sleep disturbance (13.33%. In prednisolone group, other side effects were hyperglycemia(33.33%, hypertension(40%, gastritis (33.33%, nausea, vomiting (13.33% in each , reactivation of tuberculosis, herpes zoster infection, sleep disturbance, and mood change were 6.66% in each group. Conclusion: In the light of the findings of the study, we conclude that each of the treatment of dexamethasone group and prednisolone group is individually effective and safe in the treatment of pemphigus vulgaris but adverse effects are less in parenteral dexamethasone group than oral prednisolone group. So parenteral dexamethasone can be used as an alternative drug in the treatment of pemphigus vulgaris.

Introduction and methodology – Guidelines on Parenteral Nutrition, Chapter 1

Jauch, K. W.

2009-11-01

Full Text Available Guidelines for Parenteral Nutrition were prepared by the German Society for Nutritional Medicine (http://www.dgem.de/, in collaboration with other medical associations to provide guidance for quality assurance for parenteral nutrition (PN practice, and to promoting health and quality of life of patients concerned. A coordination team proposed topics, working group leaders who along with working group members performed systematic literatur searches and drafted recommendations in a nominal group process. Recommendations were discussed and agreed upon in a structured consensus conference process, followed by a Delphi consensus. The current English version of the guidelines was written and updated during the period between the last quarter of 2007 and the first quarter of 2009. The recommendations of the guidelines should be reviewed, and if necessary updated five years after publication.

To describe the clinical characteristics of recurrent septic peritonitis in dogs. Multicenter retrospective observational study. Client-owned dogs with recurrent septic peritonitis. Three university emergency and referral hospitals. None. Medical records from 3 veterinary university teaching hospitals were reviewed and data were collected using a standardized data collection sheet for all cases of septic peritonitis during the study period (2000-2011). Forty one dogs met the inclusion criteria for recurrent peritonitis. All dogs underwent relaparotomy. The original cause of septic peritonitis in these cases included previous surgery for gastrointestinal foreign body removal (n = 26), gastrointestinal neoplasia (n = 3), gastric or duodenal ulceration (n = 3), biliary tract leakage (n = 2), and single instance for each of the following: penetrating foreign body, hernia strangulation, intussusception, mesenteric volvulus, infection of the laparotomy incision, prostatic abscess, and trauma. Eighteen animals survived to discharge. There was no difference detected between survivors and nonsurvivors with recurrent peritonitis in terms of inciting cause, serum albumin concentration, surgical management, or provision of appropriate initial antimicrobials. The survival rate for dogs having recurrent peritonitis was 43.9% (18/41 dogs). This retrospective study did not identify any significant prognostic indicators for dogs with recurrent peritonitis and that the mortality rate for dogs having more than one surgery for septic peritonitis is similar to that reported for a single surgery for septic peritonitis. ©Veterinary Emergency and Critical Care Society 2015.

Radiophosphorus (32P) treatment of bone marrow disorders in dogs: 11 cases (1970-1987)

International Nuclear Information System (INIS)

Smith, M.; Turrel, J.M.

1989-01-01

Between March 1970 and February 1987, radiophosphorus ( 32 P) was used to treat bone marrow disorders in 6 dogs; 4 had polycythemia vera and 2 had essential thrombocythemia. Activities of 32 P given initially ranged from 2.4 to 3.3 mCi/m2. Four dogs responded well to 32 P treatment, with gradual resolution of high RBC or platelet counts. Two of these dogs died of intercurrent disease unrelated to their bone marrow disorder, before blood counts could be stabilized. Two dogs did not respond to the initial 32 P treatment nor to additional treatments with 32 P, and had clinical signs and blood counts stabilized by use of phlebotomy or chemotherapeutic agents. We reviewed and analyzed 5 other cases of bone marrow disorders in dogs treated with 32 P and included the findings from their records with the records of our 6 dogs in this retrospective analysis. Of the 8 dogs with polycythemia vera treated with 32 P, 5 were given a single treatment that controlled clinical signs and blood counts for the remainder of the follow-up period. Of the 3 dogs treated for thrombocytosis with 32 P, 2 had blood counts that responded to a single treatment

This paper reports on endoparasite infections diagnosed in 2012 by standard coproscopical techniques and coproantigen Giardia ELISA in 165 dogs used for sheep herding in 36 farms in central Germany. The overall prevalence of dogs with evidence of endoparasite infections was 27.3% (95% CI 20.6-34.7). The most frequently identified faecal forms were those of ascarids (Toxocara, 6.7%; Toxascaris 3.6%), hookworms (5.5%) and taeniid cestodes (4.2%), followed by those of Trichuris whipworms (3.0%), Capillaria aerophila (1.8%), Angiostrongylus and Crenosoma lungworms (1.2% each) and Cystoisospora canis coccidians (0.6%). Molecular identification demonstrated the seven dogs shedding taeniid eggs positive for Taenia (T.) species tapeworms (five, T. hydatigena; one, T. ovis; one Taenia sp.). Screening of the faeces with the coproantigen ELISA revealed Giardia specific antigen in 5.5% of the samples. The majority of the dogs had evidence of single endoparasite infections (22.4%) while evidence for infection with two or three parasites concurrently was found in six (3.6%) and two (1.2%) of the dogs, respectively. Dogs ≤ 1 year (n = 19) were parasitized more frequently (p < 0.05) with overall gastrointestinal parasites (63.2% vs. 20.5%), ascarids (36.8% vs. 6.8%) and Giardia spp. (21.1% vs. 3.4%) than older dogs (n = 146). Dogs which had been wormed within six months of examination tested less frequently positive for gastrointestinal helminths compared to dogs not wormed (11.1% vs. 25.0%; p = 0.0567). In addition, ear swabs taken from 43 sheep dogs in 2012 were examined, and Otodectes cynotis mites were extracted from one dog. Identification of ectoparasites collected by full body search and combing from 113 sheep dogs in the years 2011 to 2013 revealed infestation of fleas and ticks (each up to five specimens per dog) on 13 and 108 dogs, respectively, with nine dogs carrying both fleas and ticks.

Dog parks are very popular in urban areas, but there are no current studies attempting to correlate visits to dog parks and risk of colonization by enteric parasites. The purpose of this study was to determine whether dog park visitation is associated with an increased prevalence of enteric parasites or an increase in prevalence of gastrointestinal signs in dogs in northern Colorado. Feces from dogs owned by veterinary students or Veterinary Teaching Hospital staff members were submitted with a completed survey form detailing dog park attendance rates, fecal character scores, and other clinical information. Feces were examined microscopically for parasites after sugar centrifugation, for Giardia spp. cysts and Cryptosporidium spp. oocysts by a commercially available immunofluorescence assay (FA) and the FA positive samples were genotyped after PCR amplification. The Giardia assemblages were determined using the glutamate dehydrogenase (GDH) β-giardin and triose phosphate isomerase (TPI) genes and the Cryptosporidium species were determined using the heat shock protein-70 gene. A total of 129 fecal samples were assayed; 66 were from dog park attending dogs and 63 were from non-dog park-attending dogs. The overall parasite prevalence rate was 7.0% (9 of 129 samples). Dog park attending dogs were more likely to be positive for Giardia or Cryptosporidium than non-dog park-attending dogs (p=0.0279), but there was no association of gastrointestinal signs with dog park attendance or with fecal flotation or FA results. The five Giardia isolates were assemblage C and/or D and the one Cryptosporidium isolate was Ctenocephalides canis. Copyright © 2011 Elsevier B.V. All rights reserved.

Full Text Available We investigated the impact of parenteral antibiotic treatment in the early neonatal period on the evolution of bifidobacteria in the newborn. Nine babies treated with intravenous ampicillin/gentamicin in the first week of life and nine controls (no antibiotic treatment were studied. Denaturing gradient gel electrophoresis was used to investigate the composition of Bifidobacterium in stool samples taken at four and eight weeks. Bifidobacteria were detected in all control infants at both four and eight weeks, while only six of nine antibiotic-treated infants had detectable bifidobacteria at four weeks and eight of nine at eight weeks. Moreover, stool samples of controls showed greater diversity of Bifidobacterium spp. compared with antibiotic-treated infants. In conclusion, short-term parenteral antibiotic treatment of neonates causes a disturbance in the expected colonization pattern of bifidobacteria in the first months of life. Further studies are required to probiotic determine if supplementation is necessary in this patient group.

One hundred eighty-one dogs and 26 short-hair cats from suburban areas around Tirana, Albania were examined for ectoparasite infestation. The dogs were examined on several occasions from 2005 through 2009 representing three seasons: winter (December-February), spring (March-May), and summer (June-August); the cats were examined in late autumn (November). In addition, deep ear swab specimens of 30 dogs were examined for ear mites. The arthropod ectoparasite fauna of the dogs included two tick species (Rhipicephalus sanguineus and Ixodes ricinus), three mite species (Sarcoptes scabiei var. canis, Otodectes cynotis, and Demodex canis), three flea species (Ctenocephalides canis, Ctenocephalides felis, and Pulex irritans), and one louse species (Trichodectes canis). In the dogs, rates of infestation were 23.8% for R. sanguineus, 0.6% for I. ricinus, 4.4% for S. scabiei var. canis, 6.7% for O. cynotis, 0.6% for D. canis, 75.7% for C. canis, 5.0% for C. felis, 8.3% for P. irritans, and 6.6% for T. canis. Mixed infestation with two or three species of ectoparasites was recorded on 38.1% of the dogs. Fleas infested 75.7% dogs (geometric mean, 3.96; range, 1-80) and were observed in winter, spring, and summer with increasing prevalences of 64.3%, 75.9%, and 100%. Ticks parasitized 24.3% of the dogs (geometric mean, 0.41; range, 1-331). R. sanguineus ticks were recorded on 34.2% and 50% of the dogs examined in spring and summer, respectively, but were absent on the dogs during winter except for a single I. ricinus specimen observed. Prevalence of infestation with R. sanguineus, S. scabiei var. canis, C. felis, P. irritans, and T. canis did not differ between dogs 6 months of age; however, prevalence of infestation with C. canis was significantly (p 6 months old. There was no difference between the sexes for the prevalences of infestation with those parasites. The examination of the cats revealed infestation with only one species of ectoparasite, C. felis (prevalence, 100

Organization of managed clinical networking for home parenteral nutrition.

Home parenteral nutrition (HPN) is an established treatment for intestinal failure, and organization of HPN is variable throughout the UK and Europe. Managed clinical networking is the single most important feature of the UK National Health Service strategy for acute services in Scotland and has the potential to improve the management of HPN patients. This review addresses the role of managed clinical networking in HPN and compares outcome data between centres. The Scottish HPN Managed Clinical Network has published the main body of the current literature supporting the concept of managed clinical networking in this context. The Network is responsible for the organization and quality assurance of HPN provision in Scotland, and has been established for 5 years. It has captured significant patient data for the purpose of clinical audit and illustrates that this is an effective model for the management of this patient population. This review provides advice for other areas wishing to improve equity of access, and to smooth the patient journey between primary, secondary and tertiary health care in the context of artificial nutrition support.

Dog and owner demographic characteristics and dog personality trait associations.

Kubinyi, Eniko; Turcsán, Borbála; Miklósi, Adám

2009-07-01

The aim of this study was to analyze the relationships between four personality traits (calmness, trainability, dog sociability and boldness) of dogs (Canis familiaris) and dog and owner demographics on a large sample size with 14,004 individuals. German speaking dog owners could characterize their dog by filling out a form on the Internet. There were five demographic variables for dogs and nine for owners. Two statistical methods were used for investigating the associations between personality and demographic traits: the more traditional general linear methods and regression trees that are ideal for analyzing non-linear relationships in the structure of the data. The results showed that calmness is influenced primarily by the dog's age, the neutered status, the number of different types of professional training courses (e.g. obedience, agility) the dog had experienced and the age of acquisition. The least calm dogs were less than 2.5 years old, neutered and acquired after the first 12 weeks of age, while the calmest dogs were older than 6.9 years. Trainability was affected primarily by the training experiences, the dog's age, and the purpose of keeping the dog. The least trainable dogs had not received professional training at all and were older than 3 years. The most trainable dogs were those who participated in three or more types of professional training. Sociability toward conspecifics was mainly determined by the age, sex, training experience and time spent together. The least sociable dogs were older than 4.8 years and the owners spent less than 3h with the dog daily. The most sociable dogs were less than 1.5 years old. Males were less sociable toward their conspecifics than females. Boldness was affected by the sex and age of the dog and the age of acquisition. The least bold were females acquired after the age of 1 year or bred by the owner. The boldest dogs were males, acquired before the age of 12 weeks, and were younger than 2 years old.

The communication of dogs is based on complex, subtle body postures and facial expressions. Some social interaction between dogs includes physical contact. Humans generally use both verbal and tactile signals to communicate with dogs. Hence, interaction between humans and dogs might lead to conflicts because the behavioural responses of dogs to human-dog interaction may be misinterpreted and wrongly assessed. The behavioural responses of dogs to tactile human-dog interactions and human gestures are the focus of this study. The participating dogs (n = 47) were privately owned pets.They were of varying breed and gender.The test consisted of nine randomised test sequences (e. g. petting the dog's head or chest). A test sequence was performed for a period of 30 seconds. The inter-trial interval was set at 60 seconds and the test-retest interval was set at 10 minutes. The frequency and duration of the dogs'behavioural responses were recorded using INTERACT. To examine the behavioural responses of the dogs, a two-way analysis of variance within the linear mixed models procedure of IBM SPSS Statistics 19 was conducted. A significant influence of the test-sequenc order on the dogs' behaviour could be analysed for appeasement gestures (F8,137 = 2.42; p = 0.018), redirected behaviour (F8,161 = 6.31; p = 0.012) and socio-positive behaviour (F8,148 = 6.28; p = 0.012). The behavioural responses of the dogs, which were considered as displacement activities (F8,109 = 2.5; p = 0.014) differed significantly among the test sequences. The response of the dogs, measured as gestures of appeasement, redirected behaviours, and displacement activities, was most obvious during petting around the head and near the paws.The results of this study conspicuously indicate that dogs respond to tactile human-dog interactions with gestures of appeasement and displacement activities. Redirected behaviours, socio-positive behaviours as well displacement activities are behavioural responses which dogs

A series of randomized, controlled and masked field studies was conducted in veterinary patients to evaluate the efficacy of selamectin, a novel avermectin, in the treatment of naturally occurring Sarcoptes scabiei infestations on dogs and Otodectes cynotis infestations on dogs and cats. A total of 342 dogs and 237 cats participated in these studies, which were conducted at 40 veterinary practices in the USA and Europe. Animals were randomly assigned to treatment with selamectin or a positive-control product (existing approved products). Selamectin was administered as a unit dose providing a minimum of 6mgkg(-1) (range: 6-12mgkg(-1)) in a topical preparation applied to the skin in a single spot on day 0 (O. cynotis in cats, n=144), or on days 0 and 30 (O. cynotis and S. scabiei in dogs, n=83 and n=122, respectively). The presence of parasites was assessed before treatment and at 30 days (for all studies) and 60 days (for O. cynotis and S. scabiei dog studies) after first treatment. The animals were also evaluated clinically at each assessment period. Based on skin scrapings, the efficacy of selamectin against S. scabiei infestations on dogs was >95% by day 30, and 100% by day 60. Against O. cynotis, selamectin eliminated mites in 94-100% of cats by day 30, and in 90% of dogs by day 60. The positive-control products achieved similar results. Thus, selamectin was safe and effective against ear mites in dogs and cats and sarcoptic mange in dogs when used in field (veterinary patient) studies in dogs and cats of a wide variety of ages and breeds.

Job-Related Stress in Forensic Interviewers of Children with Use of Therapy Dogs Compared with Facility Dogs or No Dogs.

2018-01-01

Sexually abused children providing essential testimony regarding crimes in forensic interviews now sometimes are provided facility dogs or therapy dogs for comfort. Facility dogs are extensively trained to work with forensic interviewers; when using therapy dogs in interviews, volunteers are the dog handlers. Interviews can impact child welfare workers' mental health causing secondary traumatic stress (STS). To investigate this stress, first data were gathered on stress retrospectively for when interviewers initially started the job prior to working with a dog, and then currently, from forensic interviewers using a facility dog, a therapy or pet dog, or no dog. These retrospective and secondary traumatic stress scale (STSS) data compared job stress among interviewers of children using: a certified, workplace facility dog ( n  = 16), a volunteer's trained therapy dog or the interviewer's pet dog ( n  = 13/3), or no dog ( n  = 198). Retrospective scores of therapy dog and no dog interviewers' stress were highest for the first interviewing year 1 and then declined. Extremely or very stressful retrospective scores differed among the three groups in year 1 ( p  therapy dog group as compared with the facility dog group ( p  therapy dog users than no dog users ( p  dog users more consistently used dogs during interviews and conducted more interviews than therapy/pet dog users; both groups favored using dogs. Interviewers currently working with therapy dogs accompanied by their volunteers reported they had experienced heightened stress when they began their jobs; their high stress levels still persisted, indicating lower inherent coping skills and perhaps greater empathy among interviewers who later self-selected to work with therapy dogs. Results reveal extreme avoidant stress for interviewers witnessing children who are suffering and their differing coping approaches.

Phenobarbital is well tolerated and effective for controlling agitation or preventing convulsion at the end of life. No information is available concerning parenteral bioavailability of phenobarbital when induration develops at the injection or infusion site. We investigated whether induration at injection or infusion site is related to phenobarbital bioavailability via parenteral routes of continuous subcutaneous infusion and intermittent subcutaneous or intramuscular injection. A retrospective analysis was conducted on the medical data obtained from 18 patients who received chronic subcutaneous or intramuscular injections of phenobarbital for the prevention of convulsions and underwent plasma concentration monitoring of the drug. Patients whose concomitant medications were altered during the observation periods were excluded from the analysis. Comparisons were performed for concentration/dose (C/D) ratios obtained from patients with induration at injection or infusion sites (induration group, n = 6) and those without induration (noninduration group, n = 12). P phenobarbital may be reduced when induration develops at the injection or infusion site in patients treated parenterally by continuous subcutaneous infusion or intramuscular injection.

Full Text Available Albeit a very large number of experiments have assessed the impact of various substrates on liver regeneration after partial hepatectomy, a limited number of clinical studies have evaluated artificial nutrition in liver resection patients. This is a peculiar topic because many patients do not need artificial nutrition, while several patients need it because of malnutrition and/or prolonged inability to feeding caused by complications. The optimal nutritional regimen to support liver regeneration, within other postoperative problems or complications, is not yet exactly defined. This short review addresses relevant aspects and potential developments in the issue of postoperative parenteral nutrition after liver resection.

To reduce the incidence of catheter-related bloodstream infections in home parenteral nutrition patients, the use of taurolidine was introduced in the Sophia Children's Hospital in 2011. This introduction led to a reduction in catheter-related bloodstream infections: 12.7/1000 catheter days before the use of taurolidine, compared with 4.3/1000 catheter days afterwards (n = 7) [relative risk = 0.36, 95% confidence interval: 0.20-0.65 (P = 0.018)].

Fluralaner is a potent insecticide and acaricide with rapid and persistent efficacy. This study measured the efficacy of fluralaner flavored chews (Bravecto®, Merck Animal Health) administered to dogs against adult Ctenocephalides felis felis and egg production. Twelve purpose-bred dogs were randomly allocated to two groups of six dogs each. Dogs in treatment group 1 were administered a single fluralaner flavored chew to achieve a minimum dose of at least 25 mg/kg while treatment group 2 served as untreated controls. On Days -2, 28, 56, 84, 91, 98, 105, 112, and 120 post-treatment, each dog was infested with approximately 200 unfed cat fleas, C. felis felis (KS1 strain). Forty-eight hours after treatment and 48 h after each infestation, eggs were collected over a 3-h period, counted and viability determined. Dogs were combed to remove any remaining fleas. Treatment of dogs with oral fluralaner provided a 100% reduction in flea counts 48 h after treatment and within 48 h of every post-treatment infestation through Day122. Egg production from fluralaner treated dogs was reduced by 99.9% (two eggs from one dog) within 48 h after treatment and not a single egg (100% efficacy) was thereafter collected from treated dogs. Adult flea counts and egg production from the fluralaner-treated dogs were significantly lower than for non-treated controls at all post-treatment evaluations (P dog 48 h after treatment did not produce any adult fleas. As no additional eggs were collected from treated dogs, no viability assessment was performed. A single oral dose of fluralaner flavored chews provided 100% efficacy against repeated flea infestations on dogs for 4 months. Fluralaner reduced egg production of activity reproducing female fleas by 99.9% and then killed every single female flea before any eggs could be produced following each subsequent re-infestation for the entire 122-day evaluation period.

Seed Dormancy in Arabidopsis Requires Self-Binding Ability of DOG1 Protein and the Presence of Multiple Isoforms Generated by Alternative Splicing.

Directory of Open Access Journals (Sweden)

Kazumi Nakabayashi

2015-12-01

Full Text Available The Arabidopsis protein DELAY OF GERMINATION 1 (DOG1 is a key regulator of seed dormancy, which is a life history trait that determines the timing of seedling emergence. The amount of DOG1 protein in freshly harvested seeds determines their dormancy level. DOG1 has been identified as a major dormancy QTL and variation in DOG1 transcript levels between accessions contributes to natural variation for seed dormancy. The DOG1 gene is alternatively spliced. Alternative splicing increases the transcriptome and proteome diversity in higher eukaryotes by producing transcripts that encode for proteins with altered or lost function. It can also generate tissue specific transcripts or affect mRNA stability. Here we suggest a different role for alternative splicing of the DOG1 gene. DOG1 produces five transcript variants encoding three protein isoforms. Transgenic dog1 mutant seeds expressing single DOG1 transcript variants from the endogenous DOG1 promoter did not complement because they were non-dormant and lacked DOG1 protein. However, transgenic plants overexpressing single DOG1 variants from the 35S promoter could accumulate protein and showed complementation. Simultaneous expression of two or more DOG1 transcript variants from the endogenous DOG1 promoter also led to increased dormancy levels and accumulation of DOG1 protein. This suggests that single isoforms are functional, but require the presence of additional isoforms to prevent protein degradation. Subsequently, we found that the DOG1 protein can bind to itself and that this binding is required for DOG1 function but not for protein accumulation. Natural variation for DOG1 binding efficiency was observed among Arabidopsis accessions and contributes to variation in seed dormancy.

Parenteral nutrition (PN) covering the need for carbohydrates, amino acids, and lipids can either be compounded from single nutrients or purchased as an industrially manufactured ready-to-use regimen. This study compares a commercially available 3-chamber bag (study group) with a conventionally compounded monobag regarding nutrition efficacy, safety, and regimen preparation time. This prospective, randomized, single-blind study was conducted at 5 Chinese hospitals from October 2010-October 2011. Postsurgical patients requiring PN for at least 6 days were randomly assigned to receive the study or control regimen. Plasma concentrations of prealbumin and C-reactive protein (CRP), regimen preparation time, length of hospital stay (LOS), 30-day mortality, safety laboratory parameters, and adverse events (AEs) were recorded. In total, 240 patients (121 vs 119 in study and control groups) participated in this study. Changes in prealbumin concentrations during nutrition support (Δ Prealb(StudyGroup) = 2.65 mg/dL, P < .001 vs Δ Prealb(ControlGroup) = 0.27 mg/dL, P = .606) and CRP values were comparable. Regimen preparation time was significantly reduced in the study group by the use of 3-chamber bags (t (StudyGroup) = 4.90 ± 4.41 minutes vs t (ControlGroup) = 12.13 ± 5.62 minutes, P < .001). No differences were detected for LOS, 30-day mortality, safety laboratory parameters, and postoperative AEs (37 vs 38 in study and control groups). The PN regimen provided by the 3-chamber bag was comparable to the compounded regimen and safe in use. Time savings during regimen preparation indicates that use of 3-chamber bags simplifies the process of regimen preparation.

Beagle dogs treated by total-body irradiation (TBI) were given autologous marrow grafts in order to avoid death from marrow toxicity. Acute and delayed non-marrow toxicities of high single-dose (27 dogs) and fractionated TBI (20 dogs) delivered at 0.05 or 0.1 Gy/min were compared. Fractionated TBI was given in increments of 2 Gy every 6 hr for three increments per day. Acute toxicity and early mortality (<1 month) at identical total irradiation doses were comparable for dogs given fractionated or single-dose TBI. With single-dose TBI, 14, 16, and 18 Gy, respectively, given at 0.05 Gy/min, 0/5, 5/5, and 2/2 dogs died from acute toxicity; with 10, 12, and 14 Gy, respectively, given at 0.1 Gy/min, 1/5, 4/5, and 5/5 dogs died acutely. With fractionated TBI, 14 and 16 Gy, respectively, given at 0.1 Gy/min, 1/5, 4/5, and 2/2 dogs died auctely. Early deaths were due to radiation enteritis with or without associated septicemia (29 dogs; less than or equal to Day 10). Three dogs given 10 Gy of TBI at 0.1 Gy/min died from bacterial pneumonia; one (Day 18) had been given fractionated and two (Days 14, 22) single-dose TBI. Fifteen dogs survived beyond 1 month; eight of these had single-dose TBI (10-14 Gy) and all died within 7 months of irradiation from a syndrome consisting of hepatic damage, pancreatic fibrosis, malnutrition, wasting, and anemia. Seven of the 15 had fractionated TBI, and only one (14 Gy) died on Day 33 from hepatic failure, whereas 6 (10-14 Gy) are alive and well 250 to 500 days after irradiation. In conclusion, fractionated TBI did not offer advantages over single-dose TBI with regard to acute toxicity and early mortality; rather, these were dependent upon the total dose of TBI. The total acutely tolerated dose was dependent upon the exposure rate; however, only dogs given fractionated TBI became healthy long-term survivors

Dogs may be beneficial in reducing cardiovascular risk in their owners by providing social support and motivation for physical activity. We aimed to investigate the association of dog ownership with incident cardiovascular disease (CVD) and death in a register-based prospective nation-wide cohort (n = 3,432,153) with up to 12 years of follow-up. Self-reported health and lifestyle habits were available for 34,202 participants in the Swedish Twin Register. Time-to-event analyses with time-updated covariates were used to calculate hazard ratios (HR) with 95% confidence intervals (CI). In single- and multiple-person households, dog ownership (13.1%) was associated with lower risk of death, HR 0.67 (95% CI, 0.65-0.69) and 0.89 (0.87-0.91), respectively; and CVD death, HR 0.64 (0.59-0.70), and 0.85 (0.81-0.90), respectively. In single-person households, dog ownership was inversely associated with cardiovascular outcomes (HR composite CVD 0.92, 95% CI, 0.89-0.94). Ownership of hunting breed dogs was associated with lowest risk of CVD. Further analysis in the Twin Register could not replicate the reduced risk of CVD or death but also gave no indication of confounding by disability, comorbidities or lifestyle factors. In conclusion, dog ownership appears to be associated with lower risk of CVD in single-person households and lower mortality in the general population.

Dogs' seemingly empathic behaviour attracts general and scientific attention alike. Behaviour tests are usually not sufficiently realistic to evoke empathic-like behaviour; therefore we decided to ask owners about their experiences with their dogs in emotionally loaded situations. Owners from Hungary (N = 591) and from Germany (N = 2283) were asked to rate their level of agreement on a 1-5 Likert scale with statements about the reactivity of their dogs to their emotions and to other dogs' behaviour. We created two scales with satisfactory internal reliability: reactivity to the owner's emotion and reactivity to other dogs' behaviour. Based on an owner-dog personality matching theory, we hypothesised that the owner's empathy, as measured by the subscale on the cooperativeness character factor of the human personality, will correlate with their dog's emotional reactivity in emotionally loaded situations. In addition we also examined how anthropomorphism, contagious yawning, attitude toward the dog are related to emotional reactivity in dogs as perceived by the owner. In addition we examined how owners rate dog pictures. We found that the scale scores were largely independent from demographic and environmental variables like breed, sex, age, age at acquiring, keeping practices, training experiences and owner's age. However, anthropomorphic and emotional attitude of the owners probably biased the responses. In the German sample more empathic owners reported to have more emotionally reactive dog, as expected by the personality matching theory. More empathic owners reported to have fewer problems with their dogs and they rated a puppy picture as more cute in both countries. 62% of owners from Hungary and 36% of owner from Germany agreed with the statement "My dog is more important for me than any human being". In Germany, more empathic owners agreed less with this statement and indicated that their dogs have a tendency for contagious yawning. Owners whose attitudes

Objective: To establish the model of acute spinal infarction, to evaluate the relative factors affecting results in spinal embolization, and to provide the theoretical basis with the preoperative embolization of spinal tumors. Methods: Through the SAE of the lumbar arteries, the neuro-function of the posterior legs of dogs, MRI findings, and pathologic changes of the spinal specimen were observed in 12 dogs. The embolizing agents was gelfoam (GF). Results: The significant ischemia changes of spinal column and the corresponding muscles at the occluding spinal after embolizing more than one segmental arteries occurred in 9 dogs, but there were no paraplegia or obvious changes in 3 dogs having been embolized single lumbar arteries no matter they sent out the radiculomedullary artery (RA) or not. Paraplegia occurred in one dog after embolizing the multisegmental arteries. Conclusion: (1) The method of SAE in dog can be used to set up the experimental model of the acute ischemia of spine. (2) The occlusion in single-segmental arteries can not result in the infarction of the whole spine. (3) The serious complication may result from embolizing multisegmental spinal arteries (especially sending out RA). (4) The protecting embolization should be carried out in order to decrease the reaction during SAE in spine

Premixed parenteral nutrition (PN) can be used for PN therapy in place of traditional compounded or customized PN. Premixed PN may have a number of advantages over compounded PN such as decreased costs, decreased compounding time, reduced chance for error, and reduced incidence of bloodstream infections. However, premixed PN may not be appropriate for all patients and may have other additional costs associated with its use. This article discusses the data available with regard to the use of premixed PN, focusing on the potential advantages and disadvantages of using premixed PN, and also discusses the implementation of premixed PN in a large tertiary cancer center. © 2015 American Society for Parenteral and Enteral Nutrition.

Full Text Available In surgery, indications for artificial nutrition comprise prevention and treatment of catabolism and malnutrition. Thus in general, food intake should not be interrupted postoperatively and the re-establishing of oral (e.g. after anastomosis of the colon and rectum, kidney transplantation or enteral food intake (e.g. after an anastomosis in the upper gastrointestinal tract, liver transplantation is recommended within 24 h post surgery. To avoid increased mortality an indication for an immediate postoperatively artificial nutrition (enteral or parenteral nutrition (PN also exists in patients with no signs of malnutrition, but who will not receive oral food intake for more than 7 days perioperatively or whose oral food intake does not meet their needs (e.g. less than 60–80% for more than 14 days. In cases of absolute contraindication for enteral nutrition, there is an indication for total PN (TPN such as in chronic intestinal obstruction with a relevant passage obstruction e.g. a peritoneal carcinoma. If energy and nutrient requirements cannot be met by oral and enteral intake alone, a combination of enteral and parenteral nutrition is indicated. Delaying surgery for a systematic nutrition therapy (enteral and parenteral is only indicated if severe malnutrition is present. Preoperative nutrition therapy should preferably be conducted prior to hospital admission to lower the risk of nosocomial infections. The recommendations of early postoperative re-establishing oral feeding, generally apply also to paediatric patients. Standardised operative procedures should be established in order to guarantee an effective nutrition therapy.

The kinetics of N-isopropyl-p-[ 123 I]iodoamphetamine in rat brains were determined by serial measurements of brain uptake index (BUI) after intracarotid injection; also studied were its effects on amine uptake and release in rat's brain cortical synaptosomes; and its in vivo distribution in the dog and monkey. No specific localization in brain nuclei of the dog was seen, but there was progressive accumulation in the eyes. Rapid initial brain uptake in the ketamine-sedated monkey was noted, and further slow brain uptake occurred during the next 20 min but without retinal localization. High levels of brain activity were maintained for several hours. The quantitative initial single-pass clearance of the agent in the brain suggests its use in evaluation of regional brain perfusion. Its interaction with brain amine-binding sites suggests its possible application in studies of cerebral amine metabolism

Parenteral antibiotic treatment has been classically developed in hospitals and is considered as a hospital procedure. The development of Hospital at Home Units (HHU) has led to an increase in outpatient parenteral antibiotic therapy (OPAT) in paediatrics patients. The objective of this study is to describe our experience, as an HHU integrated within a Paediatric Department, in home antimicrobial therapy over a period of 12 years. This prospective and descriptive study included every patient with a disease requiring parenteral antimicrobial therapy who was admitted to our HHU from January 2000 to December 2012. During the study there were 163 cases on OPAT. The mean age of the patients was 11.1 years, and the sample group was comprised of 33 males and 22 feamales. The main sources of the treated infections were respiratory tract (76%), catheter-related bloodstream (9.2%), and urinary tract infections (5.5%). Amikacin was the most widely used antibiotic. Almost all treatments (96.6%) were via an intravenous route. Catheter-associated complications were more common than drug-associated complications. Successful at-home treatment was observed in 90.2% of cases. OPAT is a good and safe alternative in many paediatric diseases. Copyright © 2013 Asociación Española de Pediatría.

Industrially premixed multichamber bags or hospital-manufactured compounded products can be used for parenteral nutrition. The aim of this study was to compare the cost of these 2 approaches. Costs of compounded parenteral nutrition bags in an university hospital were calculated. A total of 600 bags that were administered during 34 days between December 10, 2009 and February 17, 2010 were included in the analysis. For quality control, specific gravity evaluation of the filled bags was performed. It was calculated that the variable cost of a hospital compounded bag was $26.15. If we take the annual fixed costs into consideration, the production cost reaches $36.09 for each unit. It was estimated that the cost for the corresponding multichamber bag was $37.79. Taking the fixed and the variable costs into account, the breakeven point of the hospital compounded and the premixed multichamber bags was seen at 5,404 units per year. In specific gravity evaluation, it was observed that the mean and interval values were inside the upper and lower control margins. In this analysis, usage of hospital-compounded parenteral nutrition bags showed a cost advantage in hospitals that treat more than 15 patients per day. In small volume hospitals, premixed multichamber bags may be more beneficial.

Since there is no information regarding quality of life of caregivers assisting patients with advanced malignancy on home parenteral nutrition, herewith we report a preliminary series of 19 patients who received total parenteral nutrition at home under the strict supervision of their relatives. The relatives of 19 incurable patients with cancer-related cachexia, discharged from the hospital with a home parenteral nutrition program, were prospectively studied. They filled out a validated questionnaire, the Family Strain Questionnaire Short Form, prior to patient discharge and after 2 weeks of home care. The questionnaire included 30 items, which explored different domains regarding the superimposed burden on caregivers in relation to the assistance given to their relatives. Our findings show that the basal level of strain was relatively high (about three quarters of positive answers) but did not increase after 2 weeks of home care. Similarly, there was no difference in the nutritional status and quality of life of the patients. Eight patients and their relatives could be also analyzed after 2 months and the results maintained unchanged. This preliminary investigation shows that home parenteral nutrition does not exacerbate the level of strain on caregivers involved in surveillance of such a supportive intervention. It is possible that the perception of an active contribution to the benefit of patients, who maintained unchanged their nutritional status and quality of life, could gratify caregivers despite the objective burden in the constant supervision of administering Parenteral Nutrition.

The nature of the relationship between companion dogs and their owners has important impact on the effect of life for both dog and owner. Identifying factors that affect the dogeowner relationship will assist the understanding of how the successful relationship is achieved and how the less...... successful relationship is mended, with potential benefits for the welfare of both species. In the present study, we investigated the effect of several dog and owner characteristics, including the personality of the dog, on the dogeowner relationship as measured by the Monash Dog Owner Relationship Scale...... (MDORS). Data were collected by inviting owners of dogs that had been tested on the Danish Dog Mentality Assessment (DMA) to answer an online questionnaire. We were able to match 421 owner answers with their dogs’ DMA test results. The questionnaire consisted of the 28 items of the MDORS, as well...

Sivasubramanian, K N; Henkin, R I

1978-11-01

Two premature infants were observed to develop behavioral and dermatologic changes and low serum zinc and copper concentrations following cessation of prolonged parenteral alimentation, while being fed exclusively with human milk. Following treatment with exogenous oral zinc supplementation, prompt relief of symptoms and increases of serum zinc and copper concentrations were observed in both infants. These patients comprise about 5% of our premature infants who are treated with parenteral alimentation for more than two weeks. We recommend that premature infants on prolonged parenteral alimentation should be monitored for changes in serum zinc and copper concentrations and, if a marked fall is observed, supplementation should be considered.

Functional MRI of the olfactory system in conscious dogs.

Directory of Open Access Journals (Sweden)

Full Text Available We depend upon the olfactory abilities of dogs for critical tasks such as detecting bombs, landmines, other hazardous chemicals and illicit substances. Hence, a mechanistic understanding of the olfactory system in dogs is of great scientific interest. Previous studies explored this aspect at the cellular and behavior levels; however, the cognitive-level neural substrates linking them have never been explored. This is critical given the fact that behavior is driven by filtered sensory representations in higher order cognitive areas rather than the raw odor maps of the olfactory bulb. Since sedated dogs cannot sniff, we investigated this using functional magnetic resonance imaging of conscious dogs. We addressed the technical challenges of head motion using a two pronged strategy of behavioral training to keep dogs' head as still as possible and a single camera optical head motion tracking system to account for residual jerky movements. We built a custom computer-controlled odorant delivery system which was synchronized with image acquisition, allowing the investigation of brain regions activated by odors. The olfactory bulb and piriform lobes were commonly activated in both awake and anesthetized dogs, while the frontal cortex was activated mainly in conscious dogs. Comparison of responses to low and high odor intensity showed differences in either the strength or spatial extent of activation in the olfactory bulb, piriform lobes, cerebellum, and frontal cortex. Our results demonstrate the viability of the proposed method for functional imaging of the olfactory system in conscious dogs. This could potentially open up a new field of research in detector dog technology.

The authors explored in dogs the marrow toxicity of single dose total body irradiation delivered from two opposing 60 Co sources at a rate of 10 cGy/min and compared results to those seen with total body irradiation administered in 100 cGy fractions with minimum interfraction intervals of 6 hr. Dogs were not given marrow transplants. They found that 200 cGy single dose total body irradiation was sublethal, with 12 of 13 dogs showing hematopoietic recovery and survival. Seven of 21 dogs given 300 cGy single dose total body irradiation survived compared to 6 of 10 dogs given 300 cGy fractionated total body irradiation. One of 28 dogs given 400 cGy single dose total body irradiation survived compared to none of six given fractionated radiation. With granulocyte colony stimulating factor (GCSF) administered from day 0-21 after 400 cGy total body irradiation, most dogs survived with hematological recovery. Because of the almost uniform success with GCSF after 400 cGy single dose total body irradiation, a study of GCSF after 400 cGy fractionated total body irradiation was deemed not to be informative and, thus, not carried out. Additional comparisons between single dose and fractionated total body irradiation were carried out with GCSF administered after 500 and 600 cGy of total body irradiation. As with lower doses of total body irradiation, no significant survival differences were seen between the two modes of total body irradiation, and only 3 of 26 dogs studied survived with complete hematological recovery. Overall, therefore, survival among dogs given single dose total body irradiation was not different from that of dogs given fractionated total body irradiation (p = .67). Similarly, the slopes of the postirradiation declines of granulocyte and platelet counts and the rates of their recovery in surviving dogs given equal total doses of single versus fractionated total body irradiation were indistinguishable. 24 refs., 3 figs., 2 tabs

2017-10-31

In the world, the inflammatory bowel disease affects an increasing number of younger and younger patients, and in some of them parenteral nutrition is an alternative to high-risk surgical intervention due to advancement of the disease and malnutrition. The aim of the study was to assess the results of home parenteral nutrition in patients with severe bowel inflammatory disease, in whom surgical treatment is associated with high risk of complications. A retrospective analysis was conducted on 46 patients, who received home parenteral nutrition instead of another surgical intervention. The inclusion criteria included home parenteral nutrition and diagnosis of Crohn's disease or ulcerative colitis. Mean number of complications requiring hospital admission per patient was 1.76, the BMI increased by 4.3 on average [kg/m2]. During parenteral nutrition, the percentage of patients, in whom anti-inflammatory or immunosuppressant drugs were completely discontinued, was 17.4%. In the whole group, at least one immunosuppressive drug was discontinued in onefifth of patients. Mean albumin level increased by 2.4 g/L, lymphocyte count dropped by 474 lymphocytes/mm3, and leukocyte count increased by 747.6/mm3. The patients described their condition as good in 87%, and 7.4% of patients were able to work. Home parenteral nutrition positively affects patient's general condition by increasing BMI and normalizing biochemical test results. The results indicate the need to consider this method as an alternative to surgical intervention in severe bowel inflammatory disease with high perioperative risk, which could reduce the complication rate.

Mass vaccination of dogs is considered fundamental for national rabies control programmes in Sri Lanka, as dog is the main reservoir and transmitter of the disease. Dogs were followed to determine the sero-prevalence of antibodies to the rabies virus. Altogether 510 previously vaccinated and unvaccinated dogs with owners (domestic dogs) and dogs without owners (stray dogs) of the local guard dog breed in different age groups recruited from Kalutara District, Sri Lanka. The dogs were vaccinated with a monovalent inactivated vaccine intramuscularly and serum antibody titres on days 0, 30, 180 and 360 were determined by the Rapid Fluorescent Focus Inhibition Test (RFFIT). The results indicated, a single dose of anti-rabies vaccination fails to generate a protective level of immunity (0.5 IU/ml) which lasts until 1 year in 40.42% of dogs without owners and 57.14% of previously unvaccinated juvenile (age: 3 months to 1 year) dogs with owners. More than one vaccination would help to maintain antibody titres above the protective level in the majority of dogs. The pattern of antibody titre development in annually vaccinated and irregularly vaccinated (not annual) adult dogs with owners is closely similar irrespective of regularity in vaccination. Previously vaccinated animals have higher (2 IU/ml) antibody titres to begin with and have a higher antibody titre on day 360 too. They show a very good antibody titre by day 180. Unvaccinated animals start with low antibody titre and return to low titres by day 360, but have a satisfactory antibody titre by day 180. A single dose of anti-rabies vaccination is not sufficient for the maintenance of antibody titres for a period of 1 year in puppies, juvenile dogs with owners and in dogs without owners. Maternal antibodies do not provide adequate protection to puppies of previously vaccinated dams and puppies of previously unvaccinated dams. Immunity development after vaccination seems to be closely similar in both the groups

Raghavan, Malathi; Glickman, Nita W; Glickman, Lawrence T

2006-01-01

Using dry dog food label information, the hypothesis was tested that the risk of gastric dilatation-volvulus (GDV) increases with an increasing number of soy and cereal ingredients and a decreasing number of animal-protein ingredients among the first four ingredients. A nested case-control study was conducted with 85 GDV cases and 194 controls consuming a single brand and variety of dry food. Neither an increasing number of animal-protein ingredients (P=0.79) nor an increasing number of soy and cereal ingredients (P=0.83) among the first four ingredients significantly influenced GDV risk. An unexpected finding was that dry foods containing an oil or fat ingredient (e.g., sunflower oil, animal fat) among the first four ingredients were associated with a significant (P=0.01), 2.4-fold increased risk of GDV. These findings suggest that the feeding of dry dog foods that list oils or fats among the first four label ingredients predispose a high-risk dog to GDV.

There are few licensed options for the treatment of canine sarcoptic mange. To evaluate the efficacy of fluralaner in dogs with sarcoptic mange infestation. Seventeen dogs with a diagnosis of Sarcoptes scabiei based on positive skin scrapings. A single dose of oral fluralaner was administered according to the manufacturer's instructions. Assessments of pruritus and lesions were performed every 7 days for 1 month. By Day 14 post-treatment, skin scrapings from all dogs were negative for mites. At the beginning of the study there was a negative correlation between body weight of the subject and pruritus [Pearson correlation coefficient (PCC) = -0.396, P = 0.007] and a positive correlation between pruritus and lesion severity (PCC 0.755, P = 0.0001). Significant decreases in lesion size and pruritus were observed within the first 14-21 days, respectively, and improvement in these parameters continued until the end of the study at Day 28. Fluralaner was effective in eliminating scabies mites within 14 days and significantly resolved the clinical signs associated with sarcoptic mange within 21 days after a single dose. © 2016 ESVD and ACVD.

Canine rabies represents a major - but preventable - public health threat in Chad. In preparation for a nation-wide canine parenteral mass vaccination campaign we conducted a community-based, cross-sectional multi-stage cluster survey in 40 villages in two southern and two northern regions of Chad. Our objective was to investigate rabies awareness and dog-ownership among the rural population. Almost half of the households (45%) owned dogs, with an overall dog:human ratio of 1:7.8. Southern households owned almost two thirds (701/918) of all dogs and the number of dogs per household was twice as high compared to the north (2.7 vs. 1.3, respectively). This translates into a dog:human ratio of 1:5.2 in the south and 1:16.4 in the north. Only 76% of the respondents had heard of rabies. Respondents who (1) were male, (2)>19 years, (3) had primary education or higher and (4) were of Muslim faith were more likely to have heard of rabies (prabies knowledge was positively associated with (1) southern residence, (2) any kind of education and (3) Christian or "other" religions. In contrast to rabies awareness, high level of knowledge was negatively associated with increasing age. 11% of respondents reported that at least one family member had been bitten by a dog in the past year and half of these bite victims were children. 31% of respondents knew someone who had died of rabies and twice as many (58%) reported having encountered a rabid animal. Most of the respondents could identify classical rabies symptoms (58-94%), however they lacked knowledge about rabies prevention and appropriate wound management. Only 2 out of 963 (0.5%) reported to have vaccinated their dog. A major proportion of our study population is at great risk of rabies (likely higher than 7 rabies death per million per year) due to lack of awareness of the disease, inappropriate post-bite treatment and insufficient knowledge about preventive measures. This reflects the urgent need for advocacy programs to

Mena, Karen Daniela Romero; Espitia, Olga Lucia Pinzón; Vergara, José Alejandro Daza

Parenteral support has increased the possibility of neonatal recovery. However, complications associated with its use have been documented. One commercial method developed to decrease the complications of this type of support is the ready-to-use parenteral nutrition (PN), a 3-chamber bag that provides a complete nutrient mix. This systematic review seeks, through the Preferred Reporting Items for Systematic Reviews and Meta-Analyses methodology, to establish the benefits in newborns. Seven databases and gray literature were used. The search was limited to publications from 2007-2017 and to articles written in English, Spanish, and Portuguese. Articles that did not meet the inclusion criteria and studies with low quality evaluated with the Scottish Intercollegiate Guidelines Network guidelines, which were without information about the study or analytical methods, were excluded. A total of 24,193 articles were obtained, which were initially evaluated by title and abstract according to the inclusion criteria. A total of 24,167 articles were discarded, obtaining 27 eligible for follow-up evaluation. After a detailed evaluation of the full text, 13 articles were selected. It was found that ready-to-use PN has the potential benefit to reduce the risks for infections, provide an adequate supply of nutrients, generate growth within the expected range, provide ease of use, decrease prescription errors, and potentially reduce costs. It is necessary to evaluate the short- and long-term impact of its use. © 2018 American Society for Parenteral and Enteral Nutrition.

Comparison of the effects of enteral feeding with continuous and intermittent parenteral nutrition on hepatic triglyceride secretion in human beings

Plasma triglyceride turnover was measured during steady-state conditions in 22 postoperative patients. Nine had received nutritional support with an enteral regimen, seven had received an equivalent regimen as continuous parenteral nutrition, and six received the same parenteral regimen as a cyclical infusion. After 5 days of nutritional support, each patient received an intravenous bolus of tritiated glycerol. Plasma radiolabeled triglyceride content was measured during the subsequent 24 hours. The data were analyzed by means of a simple deterministic model of plasma triglyceride kinetics and compared with the results obtained by stochastic analysis. The rates of hepatic triglyceride secretion obtained by deterministic analysis were higher than those obtained by the stochastic approach. However, the mode of delivery of the nutritional regimen did not affect the rate of hepatic triglyceride secretion regardless of the method of analysis. The results suggest that neither complete nutritional bypass of the gastrointestinal tract nor interruption of parenteral nutrition in an attempt to mimic normal eating has any effect on hepatic triglyceride secretion. Any beneficial effect that enteral feeding or cyclical parenteral nutrition may have on liver dysfunction associated with standard parenteral nutrition appears to be unrelated to changes in hepatic triglyceride secretion

Full Text Available Objective: To determine the effect of Ancylostoma caninum (A. caninum and trypanosome parasites on the immune response to vaccination in dogs in endemic environments. Methods: Sixteen dogs for the experiment were grouped into 4 of 4 members each. Group I was the uninfected control one, and GPII was infected with A. caninum; GPIII was infected with A. caninum/Trypanosoma congolense (T. congolense, and GPIV was infected with Trypanosoma brucei (T. brucei/A. caninum. The dogs were first vaccinated with antirabies vaccine before infecting GPII, GPIII and GPIV with A. caninum which were done 4 weeks after vaccination. By 2-week post-vaccination, trypanosome parasites were superimposed on both GPIII and GPIV. A secondary vaccination was given to GPI, GPII, GPIII, and GPIV by Week 12 of the experiment (4 weeks post treatment. Results: The prepatent period was (3.00 ± 1.40 days, in the conjunct infection of T. brucei/ A. caninum. It was (9.00 ± 1.10 days, in conjunct T. congolense/A. caninum. The prepatent period of A. caninum was (14.0 ± 2.0 days in the single A. caninum group and (13.0 ± 1.0 days in the conjunct trypanosome/A. caninum. At the 1st week after vaccination, the antibody titer in all the vaccinated groups (GPI, GPII, GPIII, and GPIV significantly increased (P < 0.05 and peaked at the 3rd week after vaccination. Following infections, there were marked significant decreases (P < 0.05 in the antibody production against rabies in GPII, GPIII and GPIV. The significant decrease (P < 0.05 in antibody titer was highest in the conjunct groups (GPIII and GPIV compared to the single infection (GPII. Treatment with diminazene aceturate and mebendazole did not significantly improve antibody response in the dogs. A secondary vaccination administered at the 12th week after the primary vaccination significantly increased (P < 0.05 the antibody titer with a peak at the 3rd week after the secondary vaccination. Conclusions: It was therefore concluded

1987-01-01

The effects were studied of intravenous and intramuscular administration of radioprotectives cystamine and gammaphos in dogs on the biochemical parameters of the blood serum. The activities were studied of enzymes aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, creatinine kinase, gamma-glutamyl transpeptidase, lactate dehydrogenase, malate dehydrogenase, sorbitol dehydrogenase and alpha-amylase. The contents were determined of total protein, albumin, bilirubin, urea nitrogen, creatinine, glucose, triglycerides, cholesterol, lipids, calcium, sodium and potassium. Cystamine was shown to be hepatotoxic. The intramuscular administration of gammaphos was found to be more advantageous than of cystamine. Only slight increase was observed in the activities of lactate dehydrogenase, malate dehydrogenase, and alpha-amylase. With cystamine, the changes in all biochemical parameters were most marked.

"She's a dog at the end of the day": Guide dog owners' perspectives on the behaviour of their guide dog.

Directory of Open Access Journals (Sweden)

Peter J Craigon

Full Text Available A guide dog is a domestic dog (Canis familiaris that is specifically educated to provide mobility support to a blind or visually impaired owner. Current dog suitability assessments focus on behavioural traits, including: trainability, reactivity or attention to environmental stimuli, low aggressiveness, fearfulness and stress behaviour, energy levels, and attachment behaviour. The aim of this study was to find out which aspects of guide dog behaviour are of key importance to guide dog owners themselves. Sixty-three semi-structured interview surveys were carried out with guide dog owners. Topics included the behaviour of their guide dog both within and outside their working role, and also focused on examples of behaviour which might be considered outside a guide dog owner's typical expectations. Both positive and negative examples and situations were covered. This allowed for the discovery of new perspectives and emerging themes on living and working with a guide dog. Thematic analysis of the results reveals that a dog's safe behaviour in the face of traffic was the most important positive aspect of a guide dog's behaviour and pulling or high tension on the lead and /or harness was the most discussed negative aspect. Other aspects of guide dog behaviour were highlighted as particularly pleasing or disappointing by owners including attentiveness to the task, work, environment and owner; confidence in work and decision making (with confident dogs resulting in confident owners obedience and control; calmness and locating objectives. The results reveal important areas of behaviour that are not currently considered priorities in guide dog assessments; these key areas were consistency of behaviour, the dog's maturity and the dog's behaviour in relation to children. The survey revealed a large range in what owners considered problematic or pleasing behaviours and this highlights the heterogeneity in guide dog owners and the potential multifarious roles

To estimate prevalence of clinically-relevant intestinal nematodes in UK cats and dogs using the sensitive faecal analysis technique FLOTAC. Faecal samples were collected from 171 domestic dogs and 131 domestic cats living in urban areas of Lancashire and examined for the ova of intestinal parasites using the FLOTAC technique. All tested individuals were at least 6 months old, had not been treated with anthelmintics since 6 months of age nor in the 3 weeks prior to testing. In total, 5·3% of dogs (9/171) were positive for Toxocara canis; of these, 5/9 had dogs were positive for Uncinaria stenocephala, and 3 were positive for Strongyloides species. Single animals had Ancylostoma species and Spirocerca lupi infection. All egg counts were cats (34/131) were infected with Toxocara cati; of these, 6/34 had cats were positive for Strongyloides species, four for Ancylostoma species and single case for U. stenocephala, Toxascaris leonina and S. lupi. The high prevalence and zoonotic potential of Toxocara species in cats and dogs suggests the need for greater awareness of the need for repeated treatment. The discovery of S. lupi warrants further investigation and awareness of the clinical signs that this parasite may cause in cats and dogs. © 2016 British Small Animal Veterinary Association.

The prevalence of cancer cachexia in veterinary medicine has not been studied widely, and as of yet, no definitive diagnostic criteria effectively assess this syndrome in veterinary patients. (1) To determine the patterns of weight change in dogs with appendicular osteosarcoma treated with amputation and single-agent carboplatin during the course of adjuvant chemotherapy; and (2) to determine whether postoperative weight change is a negative prognostic indicator for survival time in dogs with osteosarcoma. Eighty-eight dogs diagnosed with appendicular osteosarcoma. Animals were accrued from 3 veterinary teaching hospitals. Retrospective, multi-institutional study. Dogs diagnosed with appendicular osteosarcoma and treated with limb amputation followed by a minimum of 4 doses of single-agent carboplatin were included. Data analyzed in each patient included signalment, tumor site, preoperative serum alkaline phosphatase activity (ALP), and body weight (kg) at each carboplatin treatment. A slight increase in weight occurred over the course of chemotherapy, but this change was not statistically significant. Weight change did not have a significant effect on survival. Institution, patient sex, and serum ALP activity did not have a significant effect on survival. Weight change was not a prognostic factor in these dogs, and weight loss alone may not be a suitable method of determining cancer cachexia in dogs with appendicular osteosarcoma.

This retrospective study evaluated cases of lens luxation in dogs that were documented at the University of Zurich Veterinary Teaching Hospital between 2000 and 2011. A total 134 dogs were included in the study. This population of dogs with lens luxation represents 0.41 % of all dogs presented to the Zurich Veterinary Teaching Hospital (32'523) and 3.02 % of all dogs presented to the ophthalmology service during the same time period. The 134 dogs represented over 40 different breeds, including mixed breeds. 63 of the dogs were male, 71 were female. The 134 dogs were divided in primary lens luxation (86 of the 134 dogs, 64 %) and secondary lens luxation (48 dogs, 36 %). The most frequent causes for secondary lens luxation were glaucoma (58 %), cataract (19 %) and trauma (17 %). This study shows the predisposition for primary lens luxations in terrier breeds, Chinese Crested dogs, Pinscher and Spitz. In contrast, Siberian Huskies, Basset Hounds, Bearded Collies, Cairn Terriers, mixed breed dogs, Bolonka Zwetna, Boston Terriers, Borzoi, Doberman, Eurasian, Leonberg, Luzerner Niederlaufhund and Weimaraner suffered significantly more often from secondary lens luxation. There was no sex predilection for primary or secondary lens luxation. Dogs with primary lens luxation were on average 7.39 ± 3.02 years old, which is significantly younger than the dogs with secondary lens luxation (9.12 ± 3.38 years). Dogs with primary lens luxation showed a significantly higher rate of a bilateral development than those with secondary lens luxation (85.5 % of the dogs with primary lens luxation and only 14.5 % of the dogs with secondary lens luxation showed it in both their eyes).

Differential diagnoses for canine liver disease are commonly based on radiographic estimates of liver size, however little has been published on breed variations. Aims of this study were to describe normal radiographic liver size in Pekingese dogs and to compare normal measurements for this breed with other dog breeds and Pekingese dogs with liver disease. Liver measurements were compared for clinically normal Pekingese (n = 61), normal non-Pekingese brachycephalic (n = 45), normal nonbrachycephalic (n = 71), and Pekingese breed dogs with liver disease (n = 22). For each dog, body weight, liver length, T11 vertebral length, thoracic depth, and thoracic width were measured on right lateral and ventrodorsal abdominal radiographs. Liver volume was calculated using a formula and ratios of liver length/T11 vertebral length and liver volume/body weight ratio were determined. Normal Pekingese dogs had a significantly smaller liver volume/body weight ratio (16.73 ± 5.67, P dogs (19.54 ± 5.03) and normal nonbrachycephalic breed dogs (18.72 ± 6.52). The liver length/T11 vertebral length ratio in normal Pekingese (4.64 ± 0.65) was significantly smaller than normal non-Pekingese brachycephalic breed dogs (5.16 ± 0.74) and normal nonbrachycephalic breed dogs (5.40 ± 0.74). Ratios of liver volume/body weight and liver length/T11 vertebral length in normal Pekingese were significantly different from Pekingese with liver diseases (P dogs have a smaller normal radiographic liver size than other breeds. We recommend using 4.64× the length of the T11 vertebra as a radiographic criterion for normal liver length in Pekingese dogs. © 2012 Veterinary Radiology & Ultrasound.

Canine lymphoma (CL) is one of the most common forms of spontaneous canine neoplasia. Improved understanding of the genetic and environmental factors associated with CL may provide benefits for the study of non-Hodgkin's and Hodgkin's lymphoma in humans. Uveodermatologic lymphoma is reported in a single household of Portuguese water dog, and the etiology is discussed. A 1-year-old female intact Portuguese water dog was referred to the Ophthalmology Service of the Veterinary Teaching Hospital of the Autonomous University of Barcelona because of acute blepharospasm of the right eye in association with a multinodular dermatosis. Physical and ophthalmological examination and a complete diagnostic work-up, including skin and ocular histopathology and immunohistochemistry, were performed. Three months prior, in Galicia (Spain), 1200 km away from Barcelona, a male dog of the same litter showed very similar oculodermatological clinical signs and skin histopathology, and immunohistochemistry were obtained. The clinical diagnoses were anterior exudative uveitis, iridal masses, and secondary glaucoma. Histopathology and immunohistochemistry revealed a nonepitheliotropic lymphoma rich in B cell in dog 1 and rich in T cell in dog 2. It is proposed that an underlying genetic predisposition could have played a role in the development of lymphoma in these two young related dogs. © 2012 American College of Veterinary Ophthalmologists.

Hepatology – Guidelines on Parenteral Nutrition, Chapter 16

Directory of Open Access Journals (Sweden)

Plauth, M.

2009-11-01

Full Text Available Parenteral nutrition (PN is indicated in alcoholic steatohepatitis (ASH and in cirrhotic patients with moderate or severe malnutrition. PN should be started immediately when sufficientl oral or enteral feeding is not possible. ASH and cirrhosis patients who can be sufficiently fed either orally or enterally, but who have to abstain from food over a period of more than 12 hours (including nocturnal fasting should receive basal glucose infusion (2–3 g/kg/d. Total PN is required if such fasting periods last longer than 72 h. PN in patients with higher-grade hepatic encephalopathy (HE; particularly in HE IV° with malfunction of swallowing and cough reflexes, and unprotected airways. Cirrhotic patients or patients after liver transplantation should receive early postoperative PN after surgery if they cannot be sufficiently rally or enterally nourished. No recommendation can be made on donor or organ conditioning by parenteral administration of glutamine and arginine, aiming at minimising ischemia/reperfusion damage. In acute liver failure artificial nutrition should be considered irrespective of the nutritional state and should be commenced when oral nutrition cannot be restarted within 5 to 7 days. Whenever feasible, enteral nutrition should be administered via a nasoduodenal feeding tube.

The toxicity of hydroxyurea, a treatment for specific neoplasms, sickle-cell disease, polycythemia, and thrombocytosis that kills cells in mitosis, was assessed in repeat-dose, oral gavage studies in rats and dogs and a cardiovascular study in telemetered dogs. Hydroxyurea produced hematopoietic, lymphoid, cardiovascular, and gastrointestinal toxicity with steep dose response curves. In rats dosed for 10 days, 50 mg/kg/day was tolerated; 500 mg/kg/day produced decreased body weight gain; decreased circulating leukocytes, erythrocytes, and platelets; decreased cellularity of thymus, lymph nodes, and bone marrow; and epithelial degeneration and/or dysplasia of the stomach and small intestine; 1,500 mg/kg/day resulted in deaths on day 5. In dogs, a single dose at ≥ 250 mg/kg caused prostration leading to unscheduled euthanasia. Dogs administered 50 mg/kg/day for 1 month had decreased circulating leukocytes, erythrocytes, and platelets; increased bone marrow cellularity with decreased maturing granulocytes; increased creatinine kinase activity; and increased iron pigment in bone marrow and hepatic sinusoidal cells. In telemetered dogs, doses ≥ 15 mg/kg decreased systolic blood pressure (BP); 50 mg/kg increased diastolic BP, heart rate, and change in blood pressure over time (+dP/dt), and decreased QT and PR intervals and maximum left ventricular systolic and end diastolic pressures with measures returning to control levels within 24 hr. © 2014 by The Author(s).

The objective of this study was to describe the pharmacokinetics (PK) of cytarabine (CA) after subcutaneous (SC) administration to dogs with meningoencephalomyelitis of unknown etiology (MUE). Twelve dogs received a single SC dose of CA at 50 mg/m 2 as part of treatment of MUE. A sparse sampling technique was used to collect four blood samples from each dog from 0 to 360 min after administration. All dogs were concurrently receiving prednisone (0.5-2 mg kg -1 day -1 ). Plasma CA concentrations were measured by HPLC, and pharmacokinetic parameters were estimated using nonlinear mixed-effects modeling (NLME). Plasma drug concentrations ranged from 0.05 to 2.8 μg/ml. The population estimate (CV%) for elimination half-life and Tmax of cytarabine in dogs was 1.09 (21.93) hr and 0.55 (51.03) hr, respectively. The volume of distribution per fraction absorbed was 976.31 (10.85%) ml/kg. Mean plasma concentration of CA for all dogs was above 1.0 μg/ml at the 30-, 60-, 90-, and 120-min time points. In this study, the pharmacokinetics of CA in dogs with MUE after a single 50 mg/m 2 SC injection in dogs was similar to what has been previously reported in healthy beagles; there was moderate variability in the population estimates in this clinical population of dogs. © 2018 John Wiley & Sons Ltd.

Organophosphorus (OP) nerve agents pose tremendous threats to both military and civilian populations. The substance 1,1'-methylenebis[4-[(hydroxyimino)methyl]-pyridinium] (MMB4) is being developed as a replacement for the currently fielded 2-pyridine aldoxime, or pralidoxime (2-PAM) as a treatment for OP nerve agent-induced toxicity. The present study characterized pharmacokinetic (PK) profiles of MMB4 in male and female Sprague-Dawley rats, New Zealand White rabbits, and beagle dogs given a single intravenous (IV) administration of MMB4 dimethanesulfonate (DMS) at 55, 25, and 15 mg/kg dose, respectively. The plasma MMB4 concentration versus time profiles were biphasic for all species tested and fit a 2-compartment model with first-order elimination. There were no overt sex-related differences in the calculated PK parameters. For the rat, rabbit, and dog, the average systemic exposure parameters predicted Cmax (µg/mL) and AUC∞ (µg·h/mL) were 273 and 71.0, 115 and 48.1, and 87.4 and 39.6; the average volume of distribution (mL/kg) values to the central and peripheral compartments were 207 and 143, 242 and 172, and 198 and 213; and the average elimination half-life (hour) and clearance (mL/h/kg) values were 0.18 and 778, 0.29 and 577, and 0.32 and 430, respectively, when the PK parameters for males and females were combined. The current study revealed a similarity in the volume of distribution to the central compartment for MMB4 among the 3 species tested while demonstrating species-related differences in the elimination half-life and clearance of MMB4.

Malnutrition is very common among chronically hospitalized patients, especially those in the intensive care unit (ICU). Identifying the patients at risk and providing suitable nutritional support can prevent and/or overcome malnutrition in them. Total parenteral nutrition (TPN) and partial parenteral nutrition (PPN) are two common routes to deliver nutrition to hospitalized patients. We conducted a multicenter, prospective double blind randomized controlled trial to evaluate the benefits and compare their adverse effects of each method. 97 patients were enrolled and divided into two groups based on the inclusion criteria. Serum protein, serum albumin, serum transferrin, and total lymphocyte count were measured on days 7 and 14. We did not find any statistically significant differences in clinical status or laboratory values between the two groups but there were significant improvements in measured lab values between days 7 and 14 (pnutritional status in each groups. This study shows that both TPN and PPN can be used safely in chronic ICU patients to provide nutritional support and prevent catabolic state among chronic critically ill patients. We need to develop precise selection criteria in order to choose the patients who would benefit the most from TPN and PPN. In addition, appropriate laboratory markers are needed to monitor the metabolic requirements of the patients and assess their progress.

In urban parks, dogs, wildlife and humans can be sympatric, introducing the potential for inter- and intra-specific transmission of pathogens among hosts. This study was conducted to determine the prevalence of zoonotic and non-zoonotic gastrointestinal parasites in dogs in Calgary city parks, and assess if dog-walking behaviour, park management, history of veterinary care, and dog demographics were associated with parasitism in dogs From June to September 2010, 645 questionnaires were administered to dog owners in nine city parks to determine behavioural and demographic factors, and corresponding feces from 355 dogs were collected. Dog feces were analyzed for helminth and some protozoan species using a modified sugar flotation technique and microscopic examination, a subsample was analyzed for Giardia spp. and Cryptosporidium spp. using a direct immunofluorescence assay. Descriptive and multivariate statistics were conducted to determine associations among behaviours, demographics, and parasite prevalence and infection intensities Parasite prevalence was 50.2%. Giardia spp. (24.7%), Cryptosporidium spp. (14.7%), and Cystoisospora spp. (16.8%) were the most prevalent parasites. Helminth prevalence was low (4.1%). Presence of Giardia spp. was more likely in intact and young dogs; and infection with any parasite and Giardia spp. intensity were both positively associated with dogs visiting multiple parks coupled with a high frequency of park use and off-leash activity, and with being intact and young. Cryptosporidium spp. intensity was associated with being intact and young, and having visited the veterinarian within the previous year Our results indicate a higher overall prevalence of protozoa in dogs than previously found in Calgary. The zoonotic potential of some parasites found in park-attending dogs may be of interest for public health. These results are relevant for informing park managers, the public health sector, and veterinarians.

Beagle dogs were exposed once or semi-annually for 10 yr by inhalation to aerosols of 239 PuO 2 to study the relative doses and effects of these two types of exposures. All exposures have been completed. Dogs exposed at high levels died predominantly of radiation pneumonitis and pulmonary fibrosis. Dogs exposed at lower levels, either once or repeatedly, are dying of a variety of causes including lung cancer. Dogs have survived up to 11 yr after their first exposure. Preliminary results suggest that single and repeated exposures cause similar health effects for equal accumulated radiation doses. (author)

The renal clearances of /sup 111/In-DTPA were measured and compared with those of /sup 125/I-iothalamate in dogs using three methods: (a) constant infusion method, (b) single injection UV/P method, and (c) single injection slope method. The renal clearances of /sup 111/In-DTPA were on the average 9% higher than those of /sup 125/I-iothalamate. Its urinary excretion was approximately 50% at 1 hr and about 80% at 4 hr, and biliary excretion was negligible. Sequential scintiphotography of the renal system in dogs revealed the flow of the tracer through the kidneys, and excretion into the ureter and bladder.

The ability of 82 irradiated and sham-treated female beagles to whelp and wean pups was tested over a major portion of their reproductive life span. The dogs were exposed to 290 or 300 R of x rays (250 kVp) either as young pups, prior to puberty, or at puberty. Although all of the irradiated dogs were fertile and produced approximately the same number of litters as controls, litters of the pup irradiated and prepubertal irradiated dams surviving throughout the study were smaller than those of controls by 17 and 9 percent, respectively. Pup survival was also reduced relative to controls; the number of pups weaned was 38 percent lower in the pup irradiated group and 18 percent lower in the prepubertal irradiated group, as compared with controls. The overall reproductive ability of dogs irradiated at puberty was similar to that of sham-treated controls

Full Text Available The focus of this review is to provide an overview of the chitosan based nanoparticles for various non-parenteral applications and also to put a spotlight on current research including sustained release and mucoadhesive chitosan dosage forms. Chitosan is a biodegradable, biocompatible polymer regarded as safe for human dietary use and approved for wound dressing applications. Chitosan has been used as a carrier in polymeric nanoparticles for drug delivery through various routes of administration. Chitosan has chemical functional groups that can be modified to achieve specific goals, making it a polymer with a tremendous range of potential applications. Nanoparticles (NP prepared with chitosan and chitosan derivatives typically possess a positive surface charge and mucoadhesive properties such that can adhere to mucus membranes and release the drug payload in a sustained release manner. Chitosan-based NP have various applications in non-parenteral drug delivery for the treatment of cancer, gastrointestinal diseases, pulmonary diseases, drug delivery to the brain and ocular infections which will be exemplified in this review. Chitosan shows low toxicity both in vitro and some in vivo models. This review explores recent research on chitosan based NP for non-parenteral drug delivery, chitosan properties, modification, toxicity, pharmacokinetics and preclinical studies.

We are managing 8 home care patients who have a gastrostomy made using an endoscopic percutaneous technique as a route of parenteral alimentation. Based on our experience, the preconditions for an endoscopic percutaneous gastrostomy as a route of parenteral alimentation are 1. normal gastrointestinal function, 2. difficulty in swallowing, 3. possibility that the caregiver can manage the gastrostomy. When we performed an endoscopic percutaneous gastrostomy as a route of parenteral alimentation for 8 home care patients, we obtained the several advantages mentioned below. 1. Swallowing pneumonia was prevented. 2. Adequate amount of alimental liquid could be infused. 3. Patient could take a bath or shower with the gastrostomy, and good QOL was realized. 4. The home care patient with the gastrostomy could have a satisfactorily long life.

A simple genetic architecture underlies morphological variation in dogs.

Full Text Available Domestic dogs exhibit tremendous phenotypic diversity, including a greater variation in body size than any other terrestrial mammal. Here, we generate a high density map of canine genetic variation by genotyping 915 dogs from 80 domestic dog breeds, 83 wild canids, and 10 outbred African shelter dogs across 60,968 single-nucleotide polymorphisms (SNPs. Coupling this genomic resource with external measurements from breed standards and individuals as well as skeletal measurements from museum specimens, we identify 51 regions of the dog genome associated with phenotypic variation among breeds in 57 traits. The complex traits include average breed body size and external body dimensions and cranial, dental, and long bone shape and size with and without allometric scaling. In contrast to the results from association mapping of quantitative traits in humans and domesticated plants, we find that across dog breeds, a small number of quantitative trait loci (< or = 3 explain the majority of phenotypic variation for most of the traits we studied. In addition, many genomic regions show signatures of recent selection, with most of the highly differentiated regions being associated with breed-defining traits such as body size, coat characteristics, and ear floppiness. Our results demonstrate the efficacy of mapping multiple traits in the domestic dog using a database of genotyped individuals and highlight the important role human-directed selection has played in altering the genetic architecture of key traits in this important species.

Recent developments in protein and peptide parenteral delivery approaches

2014-01-01

Discovery of insulin in the early 1900s initiated the research and development to improve the means of therapeutic protein delivery in patients. In the past decade, great emphasis has been placed on bringing protein and peptide therapeutics to market. Despite tremendous efforts, parenteral delivery still remains the major mode of administration for protein and peptide therapeutics. Other routes such as oral, nasal, pulmonary and buccal are considered more opportunistic rather than routine application. Improving biological half-life, stability and therapeutic efficacy is central to protein and peptide delivery. Several approaches have been tried in the past to improve protein and peptide in vitro/in vivo stability and performance. Approaches may be broadly categorized as chemical modification and colloidal delivery systems. In this review we have discussed various chemical approaches such as PEGylation, hyperglycosylation, mannosylation, and colloidal carriers including microparticles, nanoparticles, liposomes, carbon nanotubes and micelles for improving protein and peptide delivery. Recent developments on in situ thermosensitive gel-based protein and peptide delivery have also been described. This review summarizes recent developments on some currently existing approaches to improve stability, bioavailability and bioactivity of peptide and protein therapeutics following parenteral administration.

Recent in vitro observations suggest that the intestine, in addition to the liver, may be an important organ of first-pass drug metabolism. While a variety of changes in intestinal morphology and function in response to continuous parenteral and enteral nutrition have been documented, the effect of different routes of alimentation on intestinal drug metabolism has not been previously investigated. Objectives of this study were to assess the contribution of intestinal pentobarbital metabolism to overall in vivo pentobarbital pharmacokinetics in the rat and to determine if differences in pentobarbital pharmacokinetics were seen between parenterally and enterally nourished animals. After 7 days of continuous infusion of amino acid-glucose mixture via a gastric or jugular vein catheter, pharmacokinetic parameters were determined after 40 mg/kg of pentobarbital was given orally or into the portal or femoral vein. Reduced systemic availability of pentobarbital after oral administration as compared to portal vein injection was seen in both alimentation groups indicating that significant intestinal metabolism of pentobarbital occurred in vivo. Total area under the pentobarbital plasma concentration-time curve was significantly greater in parenterally nourished animals as compared with enterally alimented animals after oral, portal vein and systemic vein drug administration. Differences in pentobarbital, pharmacokinetics between the two alimentation groups appeared to be primarly due to effects on hepatic pentobarbital metabolism. While the mechanism producing these changes has not been defined, differences in gut hormones release and/or pancreatic secretion in response to the two routes of alimentation may be contributory. The widespread use of enteral and parenteral alimentation in clinical medicine suggests that studies to determine if nutrition route of administration similarly influences drug metabolism in humans may be indicated.

Full Text Available As part of the continuous improvement process, a new parenterals production plant (PPP3 was constructed at the National Center for Bioproducts. The validation of the aseptic filling process is a key element to carry out before manufacturing products. Therefore, the aim of this work was to obtain documented evidence that all the operations were carried out according the regulations of Good Manufacturing Practices for liquid and lyophilized sterile products during the aseptic filling at the Parenterals Product Plant 3. The study was designed for lyophilized products connected to the manifold of the peristaltic pump and to the four rotary piston pumps. Besides, during the filling operation four interventions were planned. The validation was carried out with three consecutive batches of media fill. In the first processed lot no vial was contaminated, but in the second and third lots there was one contaminated vial. For that reason, an investigation was performed in order to know the cause of the contamination. Finally, with this wok the validated condition was obtained, following the regulations of Good Manufacturing Practices for sterile liquids and lyophilizes products during the aseptic filling process at the Parenterals Products Plant 3.

2006-05-02

Addison's disease, also known as hypoadrenocorticism, has been reported in many individual dogs, although some breeds exhibit a greater incidence than the population as a whole. Addison's is presumed to be an autoimmune mediated hereditary defect but the mode of inheritance remains unclear. In particular, the heritability and mode of inheritance have not been defined for the Portuguese Water Dog although Addison's is known to be prevalent in the breed. The analyses present clear evidence that establishes Addison's disease as an inherited disorder in the Portuguese Water Dog with an estimate of heritability of 0.49 (+/- 0.16); there were no differences in risk for disease across sexes (p > 0.49). Further, the complex segregation analysis provides suggestive evidence that Addison's disease in the Portuguese Water Dog is inherited under the control of a single, autosomal recessive locus. The high heritability and mode of inheritance of Addison's disease in the Portuguese Water Dog should enable the detection of segregating markers in a genome-wide scan and the identification of a locus linked to Addison's. Though the confirmation of Addison's disease as an autosomal recessive disorder must wait until the gene is identified, breeders of these dogs may wish to keep the present findings in mind as they plan their breeding programs to select against producing affected dogs.

2013-01-01

A 4 yr old spayed female mixed-breed dog presented with a 2 yr history of recurring increases in liver enzymes. Two congenital portosystemic shunts (PSSs) were identified using computed tomography (CT) angiography, which included a portoazygous and portorenal extrahepatic shunt. Double right renal veins were also identified. The shunts were successfully identified and attenuated with cellophane banding. Multiple congenital PSS is a rare phenomenon, but should be considered during exploratory laparotomy for PSS and in dogs with poor response to surgical attenuation of a single PSS. CT proved to be a crucial part of accurate diagnosis and surgical planning for this dog with multiple congenital PSS.

Sixty-one years after the end of the Hitler dictatorship, the history of the German Ophthalmological Society (DOG) has still hardly been investigated. According to different sources, especially the reports of the DOG congresses 1934, 1936, 1938, and 1940, the following picture can be drawn: 1. The seizure of power ("Machtergreifung") of Adolf Hitler was appreciated by most of the DOG members. 2. After a change of the constitution the DOG came under the control of the "Reichsinnenministerium". However, it escaped the egalitarianism ("Gleichschaltung") and remained relatively independent. 3. Approximately 40 % of the heads of the German university eye clinics who were the most influential DOG representatives were members of the national socialistic German working party (NSDAP). Almost all of these joined the party in 1933 or later. 4. Up to the last congress in Dresden, 1940, the DOG activities were quite extensive. After that time the activities strongly declined. 5. The "Law for the prevention of genetically disabled offspring" ("Gesetz zur Verhütung erbkranken Nachwuchses") from January 1st 1934 was intensely discussed by the DOG. Some prominent ophthalmologists and DOG members were at least in part responsible for the sterilisations because of "congenital blindness". However, as far as it is known, the DOG itself did not intervene directly concerning the practice of sterilisation. 6. Between 1932 and 1940, the DOG lost approximately 12 % of its members. Many of these stemmed from foreign countries, and many were German Jews. The latter left the DOG, as Walther Löhlein stated after the end of the war, "voluntarily". However, a main reason for leaving the DOG was very likely the feeling of being unwanted. The national socialism had several disastrous effects on ophthalmology. Although single DOG members participated in the excesses, the DOG as an organization was not directly involved. However, taking into consideration that more than 10 % of the members of the

Full Text Available The aim of this study was to assess the analgesic effectiveness of three analgesic protocols in dogs undergoing a periodontal treatment. The study was performed as a prospective, randomized, “double blind” clinical study. A total of 45 client-owned dogs scheduled for periodontal treatment were included. Dogs of Group C received carprofen (4 mg·kg-1, dogs of Group B received bupivacaine (1 mg·kg-1 and dogs of Group CB received a combination of carprofen (4 mg·kg-1 and bupivacaine (1 mg·kg-1. Carprofen was administered subcutaneously 30 min before anaesthesia, bupivacaine was administered by nerve blocks in anaesthetized dogs. Painful periodontal treatment was performed in all patients, lasting up to one hour. Modified University of Melbourne Pain Score (UMPS, Visual Analogue Scale for pain assessment (VAS, plasma glucose and serum cortisol levels were assessed 30 min before administration of analgesics (C-0, B-0, CB‑0 and 2 h after recovery from anaesthesia (C-2, B-2, CB-2. For statistical analysis Friedman test, Mann-Whitney U-test, ANOVA and Fischer exact tests were used (P < 0.05. In CB‑2 compared to CB‑0 significantly decreased modified UMPS values. In CB‑2 UMPS values were significantly lower compared to C‑2 or B‑2. In C‑2 VAS values were significantly increased compared to C‑0, and in B‑2 VAS values were significantly increased compared to B‑0. Visual Analogue Scale values were significantly lower in CB‑2 compared to C‑2 or B‑2. Significantly increased plasma glucose concentrations were found in C‑2 compared to C‑0 and in B‑2 compared to B‑0. No other significant differences were detected. Administration of carprofen, bupivacaine or their combination is sufficient for early postoperative analgesia following periodontal treatment. Carprofen-bupivacaine combination is superior to carprofen or bupivacaine administered separately.

A prospective observational study was performed in canine clinical medicine to evaluate the emetic action and adverse effects of tranexamic acid. Veterinarians treated 137 dogs with a single dose of tranexamic acid (50 mg/kg, IV) after accidental ingestion of foreign substances. If needed, a second (median, 50 mg/kg; range, 20-50 mg/kg, IV) or third dose (median, 50 mg/kg; range, 25-50 mg/kg, IV) was administered. Tranexamic acid induced emesis in 116 of 137 (84.7%) dogs. Median time to onset of emesis was 116.5 sec (range, 26-370 sec), median duration of emesis was 151.5 sec (range, 30-780 sec), and median number of emesis episodes was 2 (range, 1-8). Second and third administrations of tranexamic acid induced emesis in 64.7 and 66.7% of dogs, respectively. In total, IV administration of tranexamic acid successfully induced emesis in 129 of 137 (94.2%) dogs. Adverse effects included a tonic-clonic convulsion and hemostatic disorder in two different dogs, both of which recovered after receiving medical care. Tranexamic acid induced emesis in most dogs following a single-dose. When a single dose was not sufficient, an additional dosage effectively induced emesis. Overall, adverse effects were considered low and self-limiting.

To objectively assess whether a dog in the bedroom or bed disturbs sleep. From August 1, 2015, through December 31, 2015, we evaluated the sleep of humans and dogs occupying the same bedroom to determine whether this arrangement was conducive to sleep. The study included 40 healthy adults without sleep disorders and their dogs (no dogs dog a validated dog accelerometer for 7 nights. The mean ± SD age of the participants (88% women) was 44±14 years and body mass index was 25±6. The mean ± SD age of the dogs was 5±3 years and weight was 15±13 kg. Mean ± SD actigraphy data showed 475±101 minutes in bed, 404±99 minutes total sleep time, 81%±7% sleep efficiency, and 71±35 minutes wake time after sleep onset. The dogs' accelerometer activity during the corresponding human sleep period was characterized as mean ± SD minutes at rest, active, and at play of 413±102, 62±43, and 2±4. The dogs had mean ± SD 85%±15% sleep efficiency. Human sleep efficiency was lower if the dog was on the bed as opposed to simply in the room (P=.003). Humans with a single dog in their bedroom maintained good sleep efficiency; however, the dog's position on/off the bed made a difference. A dog's presence in the bedroom may not be disruptive to human sleep, as was previously suspected. Copyright © 2017 Mayo Foundation for Medical Education and Research. Published by Elsevier Inc.

This experiment is being conducted to study the behavior and long-term biological effects in Beagle dogs of 144 Ce inhaled in fused aluminosilicate particles in repeated inhalation exposures for comparison with similar data from dogs that were exposed only once to a similar aerosol. Four groups of nine dogs each were exposed once every eight weeks for two years (13 exposures) to achieve specified exposure goals. The 144 Ce-exposed dogs received increasing or relatively constant beta radiation dose rates in contrast to the steadily decreasing dose rate seen after a single inhalation exposure. Exposures in the first and second groups were planned to yield a cumulative absorbed dose to lung of approximately equal to 35,000 rads and those in the third group approximately equal to 17,000 rads within two years after the first exposure. Singly exposed dogs that had died with pulmonary tumors when this experiment was initiated had cumulative doses to death of 29,000 to 61,000 rads. All 13 exposures have been completed. One dog in the 4.5-μCi 144 Ce/kg body weight group died at 771 days after first exposure with emaciation, adrenal cortical degeneration and bone marrow aplasia. One control dog died accidentally during anesthesia. During the past year, two additional dogs have died. One dog in the repeated 2.5-μCi 144 Ce/kg body weight group died at 1256 days after the first exposure with radiation pneumonitis and pulmonary fibrosis and a control dog died at 1052 days with autoimmune hemolytic anemia. The remaining 32 dogs appear to be in good physical condition except for a persistent lymphopenia at approximately equal to 4 years after the first exposure. They are being maintained for life span observations

Do Dog Behavioral Characteristics Predict the Quality of the Relationship between Dogs and Their Owners?

Science.gov (United States)

Hoffman, Christy L; Chen, Pan; Serpell, James A; Jacobson, Kristen C

This paper explores whether dog behavioral characteristics predict the quality of the relationship between dogs and their owners (i.e., owner attachment to dog), and whether relations between dog behavior and owner attachment are moderated by demographic characteristics. In this study, N = 92 children and N = 60 adults from 60 dog-owning families completed questionnaires about their attachment to their pet dog, their level of responsibility for that dog, and their general attitudes toward pets. They also rated their dogs on observable behavioral characteristics. Individuals who held positive attitudes about pets and who provided much of their dog's care reported stronger attachments to their dogs. The strength of owners' attachments to their dogs was associated with dog trainability and separation problems. Relationships between owner attachment and both dog excitability and attention-seeking behavior were further moderated by demographic characteristics: for Caucasians but not for non-Caucasians, dog excitability was negatively associated with owner attachment to dog; and for adults, dog attention-seeking behavior was positively associated with owner attachment, but children tended to be highly attached to their dogs, regardless of their dogs' attention-seeking behaviors. This study demonstrates that certain dog behavioral traits are indeed associated with the strength of owners' attachments to their dogs.

Full Text Available Abstract The overall goal of this study was to estimate the prevalence of gastrointestinal (GI parasites in dogs in the city of Villahermosa in Tabasco, Mexico. The study population consisted of 302 owned dogs that had limited access to public areas. A fecal sample was collected from each animal and examined for GI parasites by conventional macroscopic analysis and centrifugal flotation. Fecal samples from 80 (26.5% dogs contained GI parasites. Of these, 58 (19.2% were positive for helminths and 22 (7.3% were positive for protozoan parasites. At least seven parasitic species were identified. The most common parasite was Ancylostoma caninum which was detected in 48 (15.9% dogs. Other parasites detected on multiple occasions were Cystoisospora spp. (n = 19, Toxocara canis (n = 7 and Giardia spp. (n = 3. Three additional parasites, Dipylidium caninum, Trichuris vulpis and Uncinaria spp., were each detected in a single dog. No mixed parasitic infections were identified. In summary, we report a moderately high prevalence of GI parasites in owned dogs in Villahermosa, Tabasco. Several parasitic species identified in this study are recognized zoonotic pathogens which illustrates the important need to routinely monitor and treat dogs that live in close proximity to humans for parasitic infections.

Benign prostatic hyperplasia and urethral stricture are common causes of urethral obstruction over 50 years of age. To evaluate the usefulness of the Gianturo expandable stent for dilatation of the urethra, 14 single stents were placed in the posterior urethra (2 in prostatic urethra, 12 in membranous urethra), 20 in the anterior urethra. And 4 six - eight connected stents were positioned in the posterior urethra to straddle at the internal sphincter or external sphincter and followed up for 2 weeks (one dog), 1 month (two dog), 2 months (one dog), 3 months (one dog), 5 months (one dog), 9 months (three dog), and 14 months (two dogs). Seven of 18 stents in the posterior urethra and 5 of 20 in the anterior urethra wee migrated during the follow-up. By 2 weeks after placements, 100% expansion was achieved in the posterior urethra, but by 1 month in the anterior urethra. Partial or complete epithelial covering of the stents was observed 1 month after stent placement in the anterior urethra, but mucosal folds were observed in the anterior and posterior urethra. Urinary incontinence was not observed in all cases. Our experience suggest that Gianturco expandable stent can be used in dilating and maintaining the lumen of the prostatic urethra and urethral stricture.

Nutrition quality control in parenteral nutrition therapy (PNT) allows the identification of inadequate processes in parenteral nutrition (PN). The objective of this study was to assess the quality of PNT at a hospital with an established nutrition support team (NST). This observational, longitudinal, analytical, and prospective study examined 100 hospitalized PNT adult patients under the care of an NST for 21 days or until death/hospital discharge. The American Society for Parenteral and Enteral Nutrition (A.S.P.E.N.) 2007 guidelines for PNT prescription were followed. PNT indications were not in accordance with the A.S.P.E.N. 2007 guidelines in 15 patients. Among the remaining 85 patients, 48 (56.5%) did not receive adequate PNT (≥80% of the total volume prescribed). Non-NST medical orders, progression to and from enteral nutrition, changes in the central venous catheter, unknown causes, and operational errors (eg, medical prescription loss, PN nondelivery, pharmacy delays, inadequate PN bag temperature) were associated with PNT inadequacy (P nutrition therapy related to estimated energy expenditure and protein requirements and glycemia levels reached the expected targets; however, the central venous catheter infection rate was higher than 6 per 1000 catheters/d and did not meet the expected targets. Despite an established NST, there was a moderate level of PNT inadequacy in indications, administration, and monitoring. It is important to establish periodic meetings among different health professionals who prescribe and deliver PNT to define responsibilities and protocols. © 2015 American Society for Parenteral and Enteral Nutrition.

Relationship Between Scarring and Dog Aggression in Pit Bull-Type Dogs Involved in Organized Dogfighting

Simple Summary Organizations responsible for placing dogs seized from dogfighting investigations often must determine if a particular dog should be euthanized because it is too dangerous or if it is safe to place the dog in an adoptive home. In this study, we examine whether the extent of scarring from dog fighting is a reliable predictor of aggression towards other dogs and therefore could be used to help make that decision. We found that dogs with 10 or more scars in the three body zones where dogfighting injuries tend to be concentrated were more likely, on average, to show aggression to other dogs. The relationship is imperfect, however. Many unscarred dogs were dog aggressive while some highly scarred dogs were not. Therefore, we recommend also assessing a dog’s behavior before making decisions about its disposition. Abstract When pit bull-type dogs are seized in an investigation of organized dogfighting, heavily scarred dogs are often assumed to be highly dog aggressive due to a history of fighting. These dogs may be deemed dangerous and euthanized based on scarring alone. We analyzed our existing data on dogs seized from four dogfighting investigations, examining the relationship between the dogs’ scars with aggression towards other dogs. Scar and wound data were tallied in three body zones where dogfighting injuries tend to be concentrated. Dog aggression was assessed using a model dog and a friendly stimulus dog in a standardized behavior evaluation. Scarring and dog aggression were significantly related, more strongly among male (Fisher’s Exact p < 0.001) than female dogs (Fisher’s Exact p = 0.05). Ten or more scars in the three body zones was a reasonable threshold with which to classify a dog as high risk for dog aggression: 82% of males and 60% of females with such scarring displayed dog aggression. However, because many unscarred dogs were dog aggressive while some highly scarred dogs were not, we recommend collecting behavioral information to

Results obtained while studying 165 patients with esophageal cancer are presented. It is shown that radiation therapy and combined treatment result in the body mass loss, in the increase of katabolic processes in organism, in the negative nitrogen balance. Weaken patients, being under starvation conditions, are subjected more often to reaction changes and complications developing during the treatment. A comparison characteristics of two methods providing the organism with nutrition is given, i.e. gastrostomy and parenteral nutrition. Shown is the advantage of the adequate parenteral nutrition preventing the appearence of reaction changes and complications, improving the subjective state of patients, homeostasis indices, promoting the elimination of esophagitis phenomena, general radiation response and reaction to chemical preparations; resulting in the increase of quantity of leucocytes at leukopenia

Polymeric microspheres have been established as a valuable parenteral drug delivery system for sustained release of therapeutic agents via subcutaneous or intramuscular injection. Biodegradable polymers which are either synthetic or from natural sources are reviewed with respect to recent advances in exploring their applications for microsphere fabrications. New information on the impact of formulation variables on the properties of microspheres formed by an emulsion method was also presented. The characterization of microspheres using advanced physical analytical techniques was also reviewed and the utilization of the information in assessing in vivo performance of the product was also highlighted. The broad clinical use of microspheres for delivery of therapeutic agents in particular biologics such as proteins has not been realized commercially. The limited availability of biodegradable polymers with a long history of regulatory approval and the challenges in gaining regulatory approval of a new polymer have hindered the development of microspheres for parenteral drug delivery.

Human occupational or environmental inhalation exposures may involve repeated or chronic exposures, but most laboratory studies of inhaled radionuclides have involved single exposures. This study was designed to compare the biological effects of repeated inhalation exposures of dogs to a relatively insoluble form of 144 Ce with existing data for singly-exposed dogs that had the same cumulative dose to the lungs two years after exposure. To date, the biological effects observed in these repeatedly-exposed dogs have been substantially different from those seen in singly-exposed dogs, particularly during the first 5 years after the initial exposure. Although pulmonary hemangiosarcoma was the prominent biological effect seen in singly-exposed dogs between 2 and 4 years after exposure, no lung tumors were seen during the 5 years after the first of the repeated exposures. This response plus other clinical observations are discussed in relation to the patterns of dose rate and cumulative dose for the different exposure conditions. (H.K.)

The efficacy of a single oral dose of a novel isoxazoline, sarolaner (Simparica™, Zoetis), for the treatment and control of flea infestations on dogs was confirmed in five laboratory studies. The studies were conducted using adult purpose-bred Beagles and/or mixed breed dogs. All animals were individually identified and housed, and were allocated randomly to treatment with either placebo or sarolaner (eight to 10 per group) based on pretreatment parasite counts. Three studies used cat flea (Ctenocephalides felis felis) strains recently isolated from the field from the US, EU, or Australia; in the fourth study a laboratory strain (KS1) with documented tolerance to a number of insecticides such as fipronil, imidacloprid, and permethrin was used. In the fifth study, dogs were infested with dog fleas, Ctenocephalides canis. Dogs were treated orally on Day 0 with a placebo or a sarolaner tablet providing a minimum dose of 2mg/kg. Dogs were infested with approximately 100 unfed, adult fleas prior to treatment and at weekly intervals post-treatment. Comb counts were conducted to determine the numbers of viable fleas at 24h after treatment and after each subsequent infestation. Efficacy against C. felis and C. canis was 99.8-100% from treatment through Day 35. In all five studies, elimination of existing infestations was achieved within 24h after dosing, with only a single live C. felis found on one dog on Day 1. Similarly, control of flea challenges was achieved within 24h after infestation throughout the 35day study periods, with only single live C. felis found on two dogs on Day 28 in one study, and on a single dog on Day 35 in another study. There were no adverse reactions to treatment with sarolaner. These studies confirmed that a single oral dose of sarolaner at 2mg/kg provided highly effective treatment of existing C. felis infestations and persistent control of C. felis on dogs for 35days after treatment. Efficacy equivalent to that seen with C. felis was

Nutrition is one of the fundamentals of care provided to critically ill adults. The volume of enteral nutrition received, however, is often much less than prescribed due to multiple functional and process issues. To deliver the prescribed volume and correct the energy deficit associated with enteral nutrition alone, parenteral nutrition can be used in combination (termed "supplemental parenteral nutrition"), but benefits of this method have not been firmly established. A multi-centre, randomised, clinical trial is currently underway to determine if prescribed energy requirements can be provided to critically ill patients by using a supplemental parenteral nutrition strategy in the critically ill. This prospective, multi-centre, randomised, stratified, parallel-group, controlled, phase II trial aims to determine whether a supplemental parenteral nutrition strategy will reliably and safely increase energy intake when compared to usual care. The study will be conducted for 100 critically ill adults with at least one organ system failure and evidence of insufficient enteral intake from six intensive care units in Australia and New Zealand. Enrolled patients will be allocated to either a supplemental parenteral nutrition strategy for 7 days post randomisation or to usual care with enteral nutrition. The primary outcome will be the average energy amount delivered from nutrition therapy over the first 7 days of the study period. Secondary outcomes include protein delivery for 7 days post randomisation; total energy and protein delivery, antibiotic use and organ failure rates (up to 28 days); duration of ventilation, length of intensive care unit and hospital stay. At both intensive care unit and hospital discharge strength and health-related quality of life assessments will be undertaken. Study participants will be followed up for health-related quality of life, resource utilisation and survival at 90 and 180 days post randomisation (unless death occurs first). This trial

Incidence and impact of dog attacks on guide dogs in the UK: an update.

Data on dog attacks on Guide Dogs' stock were reviewed to investigate the characteristics of the attacks. An average of 11.2 attacks occurred each month. Nearly all of the attacks occurred in public areas, 68.4 per cent of victim dogs were qualified guide dogs and 55.5 per cent of victim dogs were working in harness when they were attacked. Guide Dogs' stock were injured in 43.2 per cent of attacks and veterinary costs for attacks were estimated at £34,514.30. Over 40 per cent of qualified guide dogs' working ability was affected and >20 per cent of qualified guide dogs required some time off from working after a dog attack. Twenty dogs were permanently withdrawn from the Guide Dogs' programme as a result of dog attacks, 13 of which were qualified and working with guide dog owners at the time of the withdrawal; this resulted in a financial cost of >£600,000 to the charity. More importantly perhaps, temporary and permanent withdrawals have a significant impact upon the mobility and independence of guide dog owners and in many cases significantly impacted their emotional well-being.

Full Text Available Abstract Background P-wave dispersion (Pd is a new ECG index used in human cardiology and veterinary medicine. It is defined as the difference between the maximum and the minimum P-wave duration recorded from multiple different ECG leads. So far no studies were performed assessing the importance of P-wave dispersion in dogs. Methods The current study was aimed at determining proper value of Pd in healthy dogs (group I, dogs with chronic valvular disease (group II and dogs with disturbances of supraventricular conduction (group III. The tests were carried out in 53 healthy dogs, 23 dogs with chronic valvular disease and 12 dogs with disturbances of supraventricular conduction of various breeds, sexes and body weight from 1,5 to 80 kg, aged between 0,5 and 17 years, submitted to the ECG examination. ECG was acquired in dogs in a standing position with BTL SD-8 electrocardiographic device and analyzed once the recording was enlarged. P-wave duration was calculated in 9 ECG leads (I, II, III, aVR, aVL, aVF, V1, V2, V4 from 5 cardiac cycles. Results The proper P-wave dispersion in healthy dogs was determined at up to 24 ms. P-wave dispersion was statistically significant increased (p Conclusions The P-wave dispersion is a constant index in healthy dogs, that is why it can be used for evaluating P wave change in dogs with chronic valvular disease and in dogs with disturbances of supraventricular conduction.

This paper explores whether dog behavioral characteristics predict the quality of the relationship between dogs and their owners (i.e., owner attachment to dog), and whether relations between dog behavior and owner attachment are moderated by demographic characteristics. In this study, N = 92 children and N = 60 adults from 60 dog-owning families completed questionnaires about their attachment to their pet dog, their level of responsibility for that dog, and their general attitudes toward pets. They also rated their dogs on observable behavioral characteristics. Individuals who held positive attitudes about pets and who provided much of their dog’s care reported stronger attachments to their dogs. The strength of owners’ attachments to their dogs was associated with dog trainability and separation problems. Relationships between owner attachment and both dog excitability and attention-seeking behavior were further moderated by demographic characteristics: for Caucasians but not for non-Caucasians, dog excitability was negatively associated with owner attachment to dog; and for adults, dog attention-seeking behavior was positively associated with owner attachment, but children tended to be highly attached to their dogs, regardless of their dogs’ attention-seeking behaviors. This study demonstrates that certain dog behavioral traits are indeed associated with the strength of owners’ attachments to their dogs. PMID:25685855

Full Text Available When pit bull-type dogs are seized in an investigation of organized dogfighting, heavily scarred dogs are often assumed to be highly dog aggressive due to a history of fighting. These dogs may be deemed dangerous and euthanized based on scarring alone. We analyzed our existing data on dogs seized from four dogfighting investigations, examining the relationship between the dogs’ scars with aggression towards other dogs. Scar and wound data were tallied in three body zones where dogfighting injuries tend to be concentrated. Dog aggression was assessed using a model dog and a friendly stimulus dog in a standardized behavior evaluation. Scarring and dog aggression were significantly related, more strongly among male (Fisher’s Exact p < 0.001 than female dogs (Fisher’s Exact p = 0.05. Ten or more scars in the three body zones was a reasonable threshold with which to classify a dog as high risk for dog aggression: 82% of males and 60% of females with such scarring displayed dog aggression. However, because many unscarred dogs were dog aggressive while some highly scarred dogs were not, we recommend collecting behavioral information to supplement scar counts when making disposition decisions about dogs seized in dogfighting investigations.

The objective of this study was to describe the changes in plasma glucose concentration in 20 severely injured dogs suffering from dog bite wounds over a period of 72 hours from the initiation of trauma. Historical, signalment, clinical and haematological factors were investigated for their possible effect on plasma glucose concentration. Haematology was repeated every 24 hours and plasma glucose concentrations were measured at 8-hourly intervals post-trauma. On admission, 1 dog was hypoglycaemic, 8 were normoglycaemic and 11 were hyperglycaemic. No dogs showed hypoglycaemia at any other stage during the study period. The median blood glucose concentrations at each of the 10 collection points, excluding the 56-hour and 64-hour collection points, were in the hyperglycaemic range (5.8- 6.2 mmol/l). Puppies and thin dogs had significantly higher median plasma glucose concentrations than adult and fat dogs respectively (P dogs survived the 72-hour study period. Overall 13 dogs (81.3 %) made a full recovery after treatment. Three of 4 dogs that presented in a collapsed state died, whereas all dogs admitted as merely depressed or alert survived (P = 0.004). The high incidence of hyperglycaemia can possibly be explained by the "diabetes of injury" phenomenon. However, hyperglycaemia in this group of dogs was marginal and potential benefits of insulin therapy are unlikely to outweigh the risk of adverse effects such as hypoglycaemia.

2010-06-19

In a retrospective survey, researchers identified 100 incidents of attacks on guide dogs by other dogs. These were reviewed in order to determine the number, severity and impact on the handler and dog, and the characteristics of the aggressors and victims. During the study period there were more than three attacks reported each month, with 61 per cent of the attacks being upon dogs that were in harness and working with an owner or trainer. The majority of the dogs that were attacked were male (62 per cent), and the breeds that were over-represented (relative to their prevalence in the general guide dog population) were the labrador and the golden retriever x flat-coated retriever crossbreed. Most of the attacks occurred in public places between 09.00 and 15.00 and the majority (61 per cent) of the attacking dogs were off the lead at the time of the attack. Thirty-eight per cent of the attacking dogs were of bull breeds, which were over-represented among attackers compared with the proportion of this breed type in the general dog population. Veterinary attention was sought after 41 per cent of the attacks, and in 19 per cent of instances there was injury to the handler or to a member of the public. The attacks were reported to have affected the working performance and behaviour of the victim dog in 45 per cent of the instances, and two dogs had to be subsequently withdrawn from working as guide dogs.

Life-span studies of inhaled plutonium in beagle dogs

In 1970 a life-span study with over 300 beagle dogs was begun to gain an understanding of long-term health effects resulting from respiratory tract intakes of plutonium and to derive risk estimates that might be applied to plutonium and other transuranic elements. Groups of beagle dogs were given single exposures to 239 PuO 2 , 238 PuO 2 , or 239 Pu(NO 3 ) 4 to obtain graded levels of initial lung burdens ranging from 1 to 1800 Bq lung. The objective of this paper is to give you a progress report on the current life-span studies of inhaled plutonium in beagle dogs at the Pacific Northwest Laboratory. I will describe the biokinetics of inhaled plutonium in dogs and the resulting health effects. I will also mention some studies directed towards understanding the mechanism leading to these effects. Finally, I will discuss the current risk estimates derived from these studies and how they might relate to plutonium exposures in humans. 5 refs., 13 figs., 4 tabs

High genetic diversity of East Asian village dogs has recently been used to argue for an East Asian origin of the domestic dog. However, global village dog genetic diversity and the extent to which semiferal village dogs represent distinct, indigenous populations instead of admixtures of various dog breeds has not been quantified. Understanding these issues is critical to properly reconstructing the timing, number, and locations of dog domestication. To address these questions, we sampled 318 village dogs from 7 regions in Egypt, Uganda, and Namibia, measuring genetic diversity >680 bp of the mitochondrial D-loop, 300 SNPs, and 89 microsatellite markers. We also analyzed breed dogs, including putatively African breeds (Afghan hounds, Basenjis, Pharaoh hounds, Rhodesian ridgebacks, and Salukis), Puerto Rican street dogs, and mixed breed dogs from the United States. Village dogs from most African regions appear genetically distinct from non-native breed and mixed-breed dogs, although some individuals cluster genetically with Puerto Rican dogs or United States breed mixes instead of with neighboring village dogs. Thus, African village dogs are a mosaic of indigenous dogs descended from early migrants to Africa, and non-native, breed-admixed individuals. Among putatively African breeds, Pharaoh hounds, and Rhodesian ridgebacks clustered with non-native rather than indigenous African dogs, suggesting they have predominantly non-African origins. Surprisingly, we find similar mtDNA haplotype diversity in African and East Asian village dogs, potentially calling into question the hypothesis of an East Asian origin for dog domestication.

Management strategies for dog populations and their diseases include reproductive control, euthanasia and vaccination, among others. However, the effectiveness of these strategies can be severely affected by human-mediated dog movement. If immigration is important, then the location of origin of dogs imported by humans will be fundamental to define the spatial scales over which population management and research should apply. In this context, the main objective of our study was to determine the spatial extent of dog demographic processes in rural areas and the proportion of dogs that could be labeled as immigrants at multiple spatial scales. To address our objective we conducted surveys in households located in a rural landscape in southern Chile. Interviews allowed us to obtain information on the demographic characteristics of dogs in these rural settings, human influence on dog mortality and births, the localities of origin of dogs living in rural areas, and the spatial extent of human-mediated dog movement. We found that most rural dogs (64.1%) were either urban dogs that had been brought to rural areas (40.0%), or adopted dogs that had been previously abandoned in rural roads (24.1%). Some dogs were brought from areas located as far as ∼700km away from the study area. Human-mediated movement of dogs, especially from urban areas, seems to play a fundamental role in the population dynamics of dogs in rural areas. Consequently, local scale efforts to manage dog populations or their diseases are unlikely to succeed if implemented in isolation, simply because dogs can be brought from surrounding urban areas or even distant locations. We suggest that efforts to manage or study dog populations and related diseases should be implemented using a multi-scale approach. Copyright © 2016 Elsevier B.V. All rights reserved.

Full Text Available Objective: to study the efficacy of third- versus secondary-generation fatty emulsions as part of parenteral nutrition in patients operated on for gastric cancer. Subjects and methods. Envelope randomization was used to make up two groups, each comprising 10 patients, operated on for gastric cancer in the scope of gastrectomy. A control group received parenteral nutrition having the following components: Lipofundin MST/LST 20%, (500 ml daily + Nutriflex 48/150 (B. Braun (1000 ml daily, 1744 kcal/day. The study group patients were given Lipoplus 20% (500 ml daily + Nutriflex 48/150 (1000 ml daily, 1745 kcal/day. Parenteral nutrition was used on postoperative days 1 to 5. Results. Nutritional status evaluation revealed a significant increase in the concentration of total protein and albumin in the control and study group patients on postoperative day 6. The use of both second- and third-generation fatty emulsions caused a significant increase in the concentration of triglycerides on day 6 after surgery; no differences were found between the groups. On day 6 following surgery, there was a significant decrease in IL-4 in both groups (p<0.05. At the same time the Lipofundin MST/LST group showed a significantly lower concentration of IL-4 than did the study group (p<0.05. After termination of a parenteral nutrition course, the study and control groups showed a significant decrease in one of the major pro-inflammatory cytokines — IL-6. Conclusion. In the study group, the serum anti-inflammatory activity of IL-4 was more evident than that in the control group and the proinflammatory activity (IL-6 concentration decreased, which can support that as compared with the second-generation fatty emulsions, third-generation ones with a balanced omega 3 to omega-6 fatty acid ratio (1:2.7 had a normalizing effect on systemic inflammatory processes and cytokine balance with increased anti-inflammatory and reduced proinflammatory activities.

SM-295291 and SM-369926 are new parenteral 2-aryl carbapenems with strong activity against major causative pathogens of community-acquired infections such as methicillin-susceptible Staphylococcus aureus, Streptococcus pneumoniae (including penicillin-resistant strains), Streptococcus pyogenes, Enterococcus faecalis, Klebsiella pneumoniae, Moraxella catarrhalis, Haemophilus influenzae (including β-lactamase-negative ampicillin-resistant strains), and Neisseria gonorrhoeae (including ciprofloxacin-resistant strains), with MIC(90)s of ≤ 1 μg/ml. Unlike tebipenem (MIC(50), 8 μg/ml), SM-295291 and SM-369926 had no activity against hospital pathogens such as Pseudomonas aeruginosa (MIC(50), ≥ 128 μg/ml). The bactericidal activities of SM-295291 and SM-369926 against penicillin-resistant S. pneumoniae and β-lactamase-negative ampicillin-resistant H. influenzae were equal or superior to that of tebipenem and greater than that of cefditoren. The therapeutic efficacies of intravenous administrations of SM-295291 and SM-369926 against experimentally induced infections in mice caused by penicillin-resistant S. pneumoniae and β-lactamase-negative ampicillin-resistant H. influenzae were equal or superior to that of tebipenem and greater than that of cefditoren, respectively, reflecting their in vitro activities. SM-295291 and SM-369926 showed intravenous pharmacokinetics similar to those of meropenem in terms of half-life in monkeys (0.4 h) and were stable against human dehydropeptidase I. SM-368589 and SM-375769, which are medoxomil esters of SM-295291 and SM-369926, respectively, showed good oral bioavailability in rats, dogs, and monkeys (4.2 to 62.3%). Thus, 2-aryl carbapenems are promising candidates that show an ideal broad spectrum for the treatment of community-acquired infections, including infections caused by penicillin-resistant S. pneumoniae and β-lactamase-negative ampicillin-resistant H. influenzae, have low selective pressure on antipseudomonal

Comparative population genetics of the German shepherd dog in South Africa

Directory of Open Access Journals (Sweden)

N. J. Coutts

2010-01-01

Full Text Available Modern breeding practices strive to achieve distinctive phenotypic uniformity in breeds of dogs, but these strategies are associated with the inevitable loss of genetic diversity. Thus, in parallel with the morphological variation displayed by breeds, purebred dogs commonly express genetic defects as a result of the inbreeding associated with artificial selection and the reduction of selection against disease phenotypes. Microsatellite marker analyses of 15 polymorphic canine loci were used to investigate measures of genetic diversity and population differentiation within and between German-bred and South African-bred German shepherd dogs. These data were quantified by comparison with typically outbred mongrel or crossbred dogs. Both the imported and locally-bred German shepherd dogs exhibited similar levels of genetic diversity. The breed is characterised by only a moderate loss of genetic diversity relative to outbred dogs, despite originating from a single founding sire and experiencing extensive levels of inbreeding throughout the history of the breed. Non-significant population differentiation between the ancestral German and derived South African populations indicates sufficient contemporary gene flow between these populations, suggesting that migration resulting from the importation of breeding stock has mitigated the effects of random genetic drift and a population bottleneck caused by the original founder event in South Africa. Significant differentiation between the combined German shepherd dog population and the outbred dogs illustrates the effects of selection and genetic drift on the breed since its establishment just over 100 years ago.

Nitrogen sparing by 2-ketoisocaproate in parenterally fed rats

Yagi, M.; Matthews, D.E.; Walser, M.

1990-01-01

In rats receiving total parenteral nutrition with or without sodium 2-ketoisocaproate (KIC; 2.48 g.kg-1.day-1), L-[1- 13 C]leucine and [1- 14 C]KIC were constantly infused for 6 h. CO 2 production, 14 CO 2 production, 13 CO 2 enrichment, urinary urea nitrogen (N) plus ammonia N and total urinary N were measured. Whole body protein synthesis (S) was calculated in non-KIC-infused rats and also in unfed rats infused with [1- 14 C]leucine from fractional oxidation of labeled leucine (1-F), where F is fractional utilization for protein synthesis, and urea N plus ammonia N excretion (C) as S = C x F/(1-F). Addition of KIC caused a significant reduction in N excretion and a significant improvement in N balance. Fractional oxidation of labeled KIC increased, whereas fractional utilization of labeled KIC for protein synthesis decreased, but the extent of incorporation of infused KIC into newly synthesized protein (as leucine) amounted to at least 40% of the total rate of leucine incorporation into newly synthesized whole body protein. We conclude that addition of KIC spares N in parenterally fed rats and becomes a major source of leucine for protein synthesis

Are dogs (Canis familiaris) misled more by their owners than by strangers in a food choice task?

2011-01-01

Dogs are highly skilled in understanding a large variety of human social cues and use them appropriately to solve a number of different cognitive tasks. They rely on human signals even when these are contradictory or misleading and ultimately prevent them from correctly solving a task. In the following two experiments, we investigated whether the owner and a stranger differently influenced dogs' choices in food discrimination tasks. In Experiment 1, 48 dogs were tested in 3 different conditions: (1) choice between a large and a small amount of dog pellets with no demonstration; (2) choice between a large and a small amount of dog pellets after having witnessed the owner/stranger favouring the small quantity; (3) choice between two single food pellets after observing the owner/stranger choosing one of them. In Experiment 2, 48 dogs could choose between two foods of different palatability: in Condition 1, dogs chose between a slice of sausage and a dry pellet with no demonstration. In Condition 2, the same choice was available but with a person (owner/stranger) showing a preference for the dry pellet. In Condition 3, dogs chose between a single dry pellet and 8 slices of sausage, with the person (owner/stranger) showing a preference for the pellet. In both experiments, dogs conformed to the human's indications even though these led to the selection of the less advantageous option (i.e. the smaller amount of food in Experiment 1 or the low quality food in Experiment 2). However, the owner and the stranger did not differently influence the dogs' behaviour. Results show that dogs are willing to follow a person's indication even when this is visibly (if perhaps only mildly) counterproductive to them and that they are socially prepared to rely equally on cues given by the owner and an unfamiliar friendly person.

The metabolism of tiamulin hydrogen fumarate, labeled with 3H, 14C, or both, was studied in dogs, rats, and weanling pigs. After a dose of radiolabeled tiamulin, all three species excreted more radioactivity in feces (via bile) than in urine. Dogs absorbed 86% of a single oral dose of tiamulin-3H, and the disposition of the compound was similar after a single or multiple dosage regimen. The ratio of antimicrobial activity to total radioactivity in dog plasma was only about 0.25, and was still less in dog urine. After dosing with tiamulin-14C, rats and pigs excreted at least 1% of the dose as 14CO2 in expired air. In dual-labeled studies, pigs excreted less total 14C than 3H and had greater residues of 14C than 3H in edible tissues, blood, and plasma. After the administration of tiamulin-14C to pigs, radioactivity was incorporated into liver glycogen, indicating metabolic cleavage of the side chain of tiamulin. Tiamulin-3H is the isotopically-labeled compound of choice for studying metabolism and tissue residues in animals.

One of the keys to developing and sustaining a high quality OPAT program is to understand the common challenges or barriers to OPAT delivery. We review the most common challenges to starting and managing an OPAT program and give practical advice on addressing these issues.

Functional imaging provides important insights into canine brain pathologies such as behavioral problems. Two (99m) Tc-labeled single photon emission computed tomography (SPECT) cerebral blood flow tracers-ethylcysteinate dimer (ECD) and hexamethylpropylene amine oxime (HMPAO)-are commonly used in human medicine and have been used previously in dogs but intrasubject comparison of both tracers in dogs is lacking. Therefore, this study investigated whether regional distribution differences between both tracers occur in dogs as is reported in humans. Eight beagles underwent two SPECT examinations first with (99m) Tc-ECD and followed by (99m) Tc-HMPAO. SPECT scanning was performed with a triple head gamma camera equipped with ultrahigh resolution parallel hole collimators. Images were reconstructed using filtered backprojection with a Butterworth filter. Emission data were fitted to a template permitting semiquantification using predefined regions or volumes of interest (VOIs). For each VOI, perfusion indices were calculated by normalizing the regional counts per voxel to total brain counts per voxel. The obtained perfusion indices for each region for both tracers were compared with a paired Student's T-test. Significant (P < 0.05) regional differences were seen in the subcortical region and the cerebellum. Both tracers can be used to visualize regional cerebral blood flow in dogs, however, due to the observed regional differences, they are not entirely interchangeable. © 2013 Veterinary Radiology & Ultrasound.

Total body irradiation (TBI) with 800-900 rads and allogeneic bone marrow transplantation according to the regimen designated by the Seattle group has induced remissions in patients with otherwise refractory acute leukemias. Relapse of leukemia after bone marrow transplantation remains the major problem, when the Seattle set up of two opposing 60 Co-sources and a low dose rate is used in TBI. Studies in dogs with TBI at various dose rates confirmed observations in mice that gastrointestinal toxicity is unlike toxicity against hemopoietic stem cells and possibly also leukemic stem cells depending on the dose rate. However, following very high single doses (2400 R) and marrow infusion acute gastrointestinal toxicity was not prevented by the lowest dose rate studied (0.5 R/min). Fractionated TBI with fractions of 600 R in addition to 1200 R (1000 rads) permitted the application of total doses up to 300 R followed by marrow infusion without irreversible toxicity. 26 dogs given 2400-3000 R have been observed for presently up to 2 years with regard to delayed radiation toxicity. This toxicity was mild in dogs given single doses at a low dose rate or fractionated TBI. Fractionated TBI is presently evaluated with allogeneic transplants in the dog before being applied to leukemic patients

This study examined the prevalence of dog ownership and dog walking and its association with leisure-time walking among metropolitan and nonmetropolitan older adults. A telephone-based cross-sectional survey targeting Taiwanese older adults was conducted in November 2016. Data related to dog ownership, time spent dog walking (categorized as non-dog owner, non-dog walkers, and dog walkers), and sociodemographic variables were obtained from 1074 older adults. Adjusted binary logistic regression was then performed. In this sample, 12% of Taiwanese older adults owned a dog and 31% of them walked their dogs for an average of 232.13 min over 5.9 days/week (standard deviation = 2.03). Older adults living in nonmetropolitan areas were more likely to own a dog (14.7% vs. 9.1%) but less likely to walk their dog (25.9% vs. 39.6%) than were those living in metropolitan areas. Compared with non-dog owners, only older adults living in nonmetropolitan areas who were dog walkers achieved 150 min of leisure-time walking (odds ratio: 3.03, 95% confidence interval: 1.05-8.77), after adjustment for potential confounders. Older Taiwanese adults living in nonmetropolitan areas who owned and walked their dogs were more likely to achieve health-enhancing levels of leisure-time walking. Tailored physical activity interventions for promoting dog walking should be developed for older adults who are dog owners living in nonmetropolitan areas and who do not engage in dog walking.

Full Text Available The achievement of complete cure in dogs with visceral leishmaniasis is currently a great challenge, since dogs are the main reservoir for the transmission of visceral leishmaniasis to humans and they respond poorly to conventional treatment with pentavalent antimonials. In order to improve the efficacy of treatment, we developed a novel formulation for meglumine antimoniate based on the encapsulation of this drug in freeze-dried liposomes (LMA. The aim of the present study was to evaluate the biodistribution of antimony (Sb in dogs following a single intravenous bolus injection of LMA. Four healthy male mongrel dogs received LMA at 3.8 mg Sb/kg body weight and were sacrificed 3, 48 and 96 h and 7 days later. Antimony was determined in the blood, liver, spleen and bone marrow. In the bone marrow, the highest Sb concentration was observed at 3 h (2.8 µg/g wet weight whereas in the liver and spleen it was demonstrated at 48 h (43.6 and 102.4 µg/g, respectively. In these organs, Sb concentrations decreased gradually and reached levels of 19.1 µg/g (liver, 28.1 µg/g (spleen and 0.2 µg/g (bone marrow after 7 days. Our data suggest that the critical organ for the treatment with LMA could be the bone marrow, since it has low Sb levels and, presumably, high rates of Sb elimination. A multiple dose treatment with LMA seems to be necessary for complete elimination of parasites from bone marrow in dogs with visceral leishmaniasis.

'Who's a good boy?!' Dogs prefer naturalistic dog-directed speech.

Infant-directed speech (IDS) is a special speech register thought to aid language acquisition and improve affiliation in human infants. Although IDS shares some of its properties with dog-directed speech (DDS), it is unclear whether the production of DDS is functional, or simply an overgeneralisation of IDS within Western cultures. One recent study found that, while puppies attended more to a script read with DDS compared with adult-directed speech (ADS), adult dogs displayed no preference. In contrast, using naturalistic speech and a more ecologically valid set-up, we found that adult dogs attended to and showed more affiliative behaviour towards a speaker of DDS than of ADS. To explore whether this preference for DDS was modulated by the dog-specific words typically used in DDS, the acoustic features (prosody) of DDS or a combination of the two, we conducted a second experiment. Here the stimuli from experiment 1 were produced with reversed prosody, meaning the prosody and content of ADS and DDS were mismatched. The results revealed no significant effect of speech type, or content, suggesting that it is maybe the combination of the acoustic properties and the dog-related content of DDS that modulates the preference shown for naturalistic DDS. Overall, the results of this study suggest that naturalistic DDS, comprising of both dog-directed prosody and dog-relevant content words, improves dogs' attention and may strengthen the affiliative bond between humans and their pets.

[Replacement of dogs as research animals for the approval testing of plant protection products].

Box, Rainer J

2006-01-01

The replacement of animal testing using dogs for the registration of plant protection products requires a long-term step-by-step procedure. The first goal should be to achieve international agreement on using only one single study in dogs. This would result in a significant short-term reduction of the use of dogs for this purpose. The competent working groups both in the EU and the United States EPA have declared this to be their intended aim. In this context, the 90-day study is to be the preferred study from the scientific as well as the animal welfare points of view. It is proposed to set up an international expert task force within the next 12 months, which should seek to initiate a process of international harmonization of the testing requirements following the example of the International Conference of Harmonization of Technical Requirements for Medical Products, ICH. The goal should be to achieve international agreement on only one single study with dogs within the next 2 to 3 years. In addition, other valid scientific procedures, with which the use of dogs for testing can be reduced, should be critically assessed. A complete replacement of the use of dogs for plant protection product testing is suggested to take place at a later stage. This may be achieved by either deriving safety threshold values by applying a safety factor to chronic NOAEL values obtained in studies using rats for those groups of substances, for which there is evidence that the dog is the more sensitive species, or by combining the chronic rat study with other animal tests stipulated for the registration of pesticides.

Femoral vein catheterization is an alternative method of obtaining central venous access. Placement of femoral venous catheters (FVCs) is possible in the majority of patients, suitable for most indications, and associated with a low complication rate during insertion. We wished to determine the incidence of infections or other complications resulting when parenteral nutrition was delivered through FVCs. Fifty-two patients were followed from a hospital-wide population including patients in the critical care units. Triple-lumen catheters were placed by using the sterile Seldinger technique, and sites were examined daily for inflammation. Bacteriologic surveillance was accomplished by submitting the catheter tip for semiquantitative cultures. If catheter line sepsis was suspected, blood samples for cultures were drawn through the catheter and peripherally. The rate of occurrence of colonized catheters was 9.6% (five of 52), and catheter sepsis was found in one case (1.9%). Other than inflammation at six (11.5%) of 52 catheter sites, noninfectious complications of FVCs were not found. On the basis of these findings, we consider FVC-delivered parenteral alimentation a safe and effective alternative to other forms of central venous access.

2017-01-16

The efficacy of fluralaner for the treatment of Otodectes cynotis infestations in dogs and cats was evaluated after oral (dogs) or topical administration (dogs and cats). Twenty-four dogs and sixteen cats were experimentally infested with O. cynotis and randomly allocated to equal sized groups (n = 8/group). Dog groups were treated once, either orally with fluralaner at a minimum dose of 25 mg/kg body weight, topically with fluralaner at a dose of 25 mg/kg body weight or topically with saline solution (control). Cat groups were treated once, either topically with fluralaner at a dose of 40 mg/kg body weight or topically with saline solution. Ears of all animals were examined otoscopically for live visible mites and the amount of debris and cerumen before, and 14 and 28 days after treatment. Twenty-eight days after treatment, animals were sedated and both ears were flushed to obtain the total number of live mites per animal. The efficacy was calculated, based on the results of the ear flushing, by comparing mean live mite counts in the fluralaner treated groups versus the saline solution treated group. A single topical treatment of cats with fluralaner reduced the mean mite counts by 100% (P dogs with fluralaner reduced the mean mite counts by 99.8% (P Cats treated topically with fluralaner had no mites visible during otoscopic examination at either 14 or 28 days after treatment. All dogs treated orally or topically with fluralaner had no mites visible during otoscopic examination at 28 days after treatment. At 14 days after treatment, only 1-2 mites were visible in three dogs (oral treatment: 2 dogs, topical treatment: 1 dog). All fluralaner-treated animals showed improvement in the amount of cerumen exudation compared with observations performed before treatment. No treatment related adverse events were observed in any dogs or cats enrolled in these studies. In this study, fluralaner administered topically to cats and orally or topically to dogs was

There are various hypotheses on dog domestication based on archeological and genetic studies. Although many studies have been conducted on the origin of dogs, the existing literature about the ancestry, diversity, and population structure of Korean dogs is sparse. Therefore, this study is focused on the origin, diversity and population structure of Korean dogs. The study sample comprised four major categories, including non-dogs (coyotes and wolves), ancient, modern and Korean dogs. Selected samples were genotyped using an Illumina CanineHD array containing 173,662 single nucleotide polymorphisms. The genome-wide data were filtered using quality control parameters in PLINK 1.9. Only autosomal chromosomes were used for further analysis. The negative off-diagonal variance of the genetic relationship matrix analysis depicted, the variability of samples in each population. FIS (inbreeding rate within a population) values indicated, a low level of inbreeding within populations, and the patterns were in concordance with the results of Nei's genetic distance analysis. The lowest FST (inbreeding rate between populations) values among Korean and Chinese breeds, using a phylogenetic tree, multi-dimensional scaling, and a TreeMix likelihood tree showed Korean breeds are highly related to Chinese breeds. The Korean breeds possessed a unique and large diversity of admixtures compared with other breeds. The highest and lowest effective population sizes were observed in Korean Jindo Black (485) and Korean Donggyeong White (109), respectively. The historical effective population size of all Korean dogs showed declining trend from the past to present. It is important to take immediate action to protect the Korean dog population while conserving their diversity. Furthermore, this study suggests that Korean dogs have unique diversity and are one of the basal lineages of East Asian dogs, originating from China.

A guide dog is a domestic dog (Canis familiaris) that is specifically educated to provide mobility support to a blind or visually impaired owner. Current dog suitability assessments focus on behavioural traits, including: trainability, reactivity or attention to environmental stimuli, low aggressiveness, fearfulness and stress behaviour, energy levels, and attachment behaviour. The aim of this study was to find out which aspects of guide dog behaviour are of key importance to guide dog owners themselves. Sixty-three semi-structured interview surveys were carried out with guide dog owners. Topics included the behaviour of their guide dog both within and outside their working role, and also focused on examples of behaviour which might be considered outside a guide dog owner’s typical expectations. Both positive and negative examples and situations were covered. This allowed for the discovery of new perspectives and emerging themes on living and working with a guide dog. Thematic analysis of the results reveals that a dog’s safe behaviour in the face of traffic was the most important positive aspect of a guide dog’s behaviour and pulling or high tension on the lead and /or harness was the most discussed negative aspect. Other aspects of guide dog behaviour were highlighted as particularly pleasing or disappointing by owners including attentiveness to the task, work, environment and owner; confidence in work and decision making (with confident dogs resulting in confident owners) obedience and control; calmness and locating objectives. The results reveal important areas of behaviour that are not currently considered priorities in guide dog assessments; these key areas were consistency of behaviour, the dog’s maturity and the dog’s behaviour in relation to children. The survey revealed a large range in what owners considered problematic or pleasing behaviours and this highlights the heterogeneity in guide dog owners and the potential multifarious roles of the

Forty-nine dogs inhaled graded levels of 144 Ce that resulted in initial lung burdens ranging from 0.004-140 μCi/kg 0.15-5200 kBq/kg) body weight. Five control dogs inhaled nonradioactive fused aluminosilicate particles. Forty-one of the 144 Ce-exposed dogs have died: 11 with lung tumors 4 with tumors of the tracheobronchial lymph nodes, with a nasal cavity tumor, and 9 with non neoplastic diseases of the respiratory tract. Observations are continuing on the 8 144 Ce-exposed dogs that are surviving at this time. (author)

Dog-directed speech: why do we use it and do dogs pay attention to it?

Pet-directed speech is strikingly similar to infant-directed speech, a peculiar speaking pattern with higher pitch and slower tempo known to engage infants' attention and promote language learning. Here, we report the first investigation of potential factors modulating the use of dog-directed speech, as well as its immediate impact on dogs' behaviour. We recorded adult participants speaking in front of pictures of puppies, adult and old dogs, and analysed the quality of their speech. We then performed playback experiments to assess dogs' reaction to dog-directed speech compared with normal speech. We found that human speakers used dog-directed speech with dogs of all ages and that the acoustic structure of dog-directed speech was mostly independent of dog age, except for sound pitch which was relatively higher when communicating with puppies. Playback demonstrated that, in the absence of other non-auditory cues, puppies were highly reactive to dog-directed speech, and that the pitch was a key factor modulating their behaviour, suggesting that this specific speech register has a functional value in young dogs. Conversely, older dogs did not react differentially to dog-directed speech compared with normal speech. The fact that speakers continue to use dog-directed with older dogs therefore suggests that this speech pattern may mainly be a spontaneous attempt to facilitate interactions with non-verbal listeners. © 2017 The Author(s).

We read conspecifics' social cues effortlessly, but little is known about our abilities to understand social gestures of other species. To investigate the neural underpinnings of such skills, we used functional magnetic resonance imaging to study the brain activity of experts and non-experts of dog behavior while they observed humans or dogs either interacting with, or facing away from a conspecific. The posterior superior temporal sulcus (pSTS) of both subject groups dissociated humans facing toward each other from humans facing away, and in dog experts, a distinction also occurred for dogs facing toward vs. away in a bilateral area extending from the pSTS to the inferior temporo-occipital cortex: the dissociation of dog behavior was significantly stronger in expert than control group. Furthermore, the control group had stronger pSTS responses to humans than dogs facing toward a conspecific, whereas in dog experts, the responses were of similar magnitude. These findings suggest that dog experts' brains distinguish socially relevant body postures similarly in dogs and humans.

Virus-like particles (VLPs) are being evaluated as a candidate rotavirus vaccine. The immunogenicity and protective efficacy of different formulations of VLPs administered parenterally to rabbits were tested. Two doses of VLPs (2/6-, G3 2/6/7-, or P[2], G3 2/4/6/7-VLPs) or SA11 simian rotavirus in Freund’s adjuvants, QS-21 (saponin adjuvant), or aluminum phosphate (AlP) were administered. Serological and mucosal immune responses were evaluated in all vaccinated and control rabbits before and after oral challenge with 103 50% infective doses of live P[14], G3 ALA lapine rotavirus. All VLP- and SA11-vaccinated rabbits developed high levels of rotavirus-specific serum and intestinal immunoglobulin G (IgG) antibodies but not intestinal IgA antibodies. SA11 and 2/4/6/7-VLPs afforded similar but much higher mean levels of protection than 2/6/7- or 2/6-VLPs in QS-21. The presence of neutralizing antibodies to VP4 correlated (P < 0.001, r = 0.55; Pearson’s correlation coefficient) with enhanced protection rates, suggesting that these antibodies are important for protection. Although the inclusion of VP4 resulted in higher mean protection levels, high levels of protection (87 to 100%) from infection were observed in individual rabbits immunized with 2/6/7- or 2/6-VLPs in Freund’s adjuvants. Therefore, neither VP7 nor VP4 was absolutely required to achieve protection from infection in the rabbit model when Freund’s adjuvant was used. Our results show that VLPs are immunogenic when administered parenterally to rabbits and that Freund’s adjuvant is a better adjuvant than QS-21. The use of the rabbit model may help further our understanding of the critical rotavirus proteins needed to induce active protection. VLPs are a promising candidate for a parenterally administered subunit rotavirus vaccine. PMID:9765471

Psychological effects of dog ownership: role strain, role enhancement, and depression.

The purpose of this study is to examine the link between multiple roles and depression and to attempt to provide a clearer answer to the question of what effect, if any, the role of dog ownership plays. Role strain and role enhancement theories are drawn upon to study this relationship. Ordinary least squares regression is used to examine a national sample of 201 adults in the United States. Findings revealed sex and marital status differences in the relationship between dog ownership and well-being, with women and single adults more likely to benefit from dog ownership. The findings presented here suggest that inattention to variations in marital status and sex may have been one factor in the inconsistency in the literature on pets and well-being.

1979-01-01

Rats and dogs inhaled aerosols of 239 PuO 2 at comparable ages relative to their lifespan. Both received a single exposure. The estimated lung doses at death in dogs were between 1100 and 11,000 rad. From two inhalation experiments, rats receiving doses in this range were chosen from the high-level exposed animals for comparison. Based on this data base, several comparisons were investigated. Metabolism of the material was compared for all animals and for animals which developed lung tumors. The differences in histopathology and tumor incidence in the lung were also reviewed. Although there were several differences between species, there were also many similarities. On-going research in dogs should produce data which will allow clarification of these relationships

The IGF1 small dog haplotype is derived from Middle Eastern grey wolves

Full Text Available Abstract Background A selective sweep containing the insulin-like growth factor 1 (IGF1 gene is associated with size variation in domestic dogs. Intron 2 of IGF1 contains a SINE element and single nucleotide polymorphism (SNP found in all small dog breeds that is almost entirely absent from large breeds. In this study, we surveyed a large sample of grey wolf populations to better understand the ancestral pattern of variation at IGF1 with a particular focus on the distribution of the small dog haplotype and its relationship to the origin of the dog. Results We present DNA sequence data that confirms the absence of the derived small SNP allele in the intron 2 region of IGF1 in a large sample of grey wolves and further establishes the absence of a small dog associated SINE element in all wild canids and most large dog breeds. Grey wolf haplotypes from the Middle East have higher nucleotide diversity suggesting an origin there. Additionally, PCA and phylogenetic analyses suggests a closer kinship of the small domestic dog IGF1 haplotype with those from Middle Eastern grey wolves. Conclusions The absence of both the SINE element and SNP allele in grey wolves suggests that the mutation for small body size post-dates the domestication of dogs. However, because all small dogs possess these diagnostic mutations, the mutations likely arose early in the history of domestic dogs. Our results show that the small dog haplotype is closely related to those in Middle Eastern wolves and is consistent with an ancient origin of the small dog haplotype there. Thus, in concordance with past archeological studies, our molecular analysis is consistent with the early evolution of small size in dogs from the Middle East.

Principles of feeding cancer patients via enteral or parenteral nutrition during radiotherapy

International Nuclear Information System (INIS)

Fietkau, R.

1998-01-01

Background: The nutritional status of cancer patients is frequently impaired already before any therapy starts and may deteriorate even more by radio(chemo)therapy. Methods: This review describes the possibilities and risks of enteral and parenteral nutrition during radiotherapy. The indications of enteral nutrition will be derived from own results. Results: Enteral nutrition is the most preferable way of artificial long-term nutrition. In a prospective non-randomized trial we demonstrated that enteral nutrition via percutaneous endoscopic gastrostomy (PEG) not only improves the anthropometric and biochemical parameters during radio(chemo)therapy but also the quality of life of patients with advanced cancers of the head and neck. Moreover supportive use of megestrolacetate can improve the nutritional status. Parenteral nutrition is only recommended if enteral nutrition is not possible e.g. during radio(chemo)therapy of tumors of the upper gastrointestinal tract. Conclusions: Today adequate nutritional support is feasible during intensive radio(chemo)therapy. (orig.) [de

Factors associated with the success of rabies vaccination of dogs in Sweden

Directory of Open Access Journals (Sweden)

Rivera Esteban

2011-03-01

Full Text Available Abstract Background United Kingdom, Ireland, Malta and Sweden maintain their national provisions for a transitional period regarding rules concerning rabies vaccination and individual serological test for rabies neutralizing antibodies. The purpose of vaccinating dogs against rabies is to establish pre-exposure immunity and protect individual animals from contracting rabies. The aim of the study was to investigate factors associated with reaching the internationally accepted threshold antibody titre of 0.5 IU/mL after rabies vaccination of dogs. Methods The study was a prospective single cohort study including 6,789 samples from Swedish dogs vaccinated with commercially available vaccines in Sweden, and the dog's antibody responses were determined by the OIE approved FAVN test. Information on potential risk factors; breed, age, gender, date of vaccination, vaccine label and the number of vaccinations, was collected for each dog. Associations between the dependent variable, serological response ≥ 0.5 IU/mL or Results Of 6,789 vaccinated dogs, 6,241 (91.9% had an approved test result of ≥ 0.5 IU/mL. The results of the multivariable logistic regression analysis showed that vaccinating with vaccine B reduced the risk of having antibody titres of 5 years of age to have antibody titres of Conclusions The probability of success of rabies vaccinations of dogs depends on type of vaccine used, number of rabies vaccinations, the breed size of the dog, age at vaccination, and number of days after vaccination when the antibody titres are tested. The need for a booster vaccination regimen is recommended for larger breeds of dog.

Dietary nitrate and nitrite are sources of gastric NO, which modulates blood flow, mucus production, and microbial flora. However, the intake and importance of these anions in infants is largely unknown. Nitrate and nitrite levels were measured in breast milk of mothers of preterm and term infants, infant formulas, and parenteral nutrition. Nitrite metabolism in breast milk was measured after freeze-thawing, at different temperatures, varying oxygen tensions, and after inhibition of potential nitrite-metabolizing enzymes. Nitrite concentrations averaged 0.07 ± 0.01 μM in milk of mothers of preterm infants, less than that of term infants (0.13 ± 0.02 μM) (P milk. Concentrations in parenteral nutrition were equivalent to or lower than those of breast milk. Freeze-thawing decreased nitrite concentration ~64%, falling with a half-life of 32 minutes at 37°C. The disappearance of nitrite was oxygen-dependent and prevented by ferricyanide and 3 inhibitors of lactoperoxidase. Nitrite concentrations in breast milk decrease with storage and freeze-thawing, a decline likely mediated by lactoperoxidase. Compared to adults, infants ingest relatively little nitrite and nitrate, which may be of importance in the modulation of blood flow and the bacterial flora of the infant GI tract, especially given the protective effects of swallowed nitrite. © 2013 American Society for Parenteral and Enteral Nutrition.

Dogs catch human yawns

OpenAIRE

Joly-Mascheroni, Ramiro M; Senju, Atsushi; Shepherd, Alex J

2008-01-01

This study is the first to demonstrate that human yawns are possibly contagious to domestic dogs (Canis familiaris). Twenty-nine dogs observed a human yawning or making control mouth movements. Twenty-one dogs yawned when they observed a human yawning, but control mouth movements did not elicit yawning from any of them. The presence of contagious yawning in dogs suggests that this phenomenon is not specific to primate species and may indicate that dogs possess the capacity for a rudimentary f...

Do Dogs Provide Information Helpfully?

Full Text Available Dogs are particularly skilful during communicative interactions with humans. Dogs' abilities to use human communicative cues in cooperative contexts outcompete those of other species, and might be the result of selection pressures during domestication. Dogs also produce signals to direct the attention of humans towards outside entities, a behaviour often referred to as showing behaviour. This showing behaviour in dogs is thought to be something dogs use intentionally and referentially. However, there is currently no evidence that dogs communicate helpfully, i.e. to inform an ignorant human about a target that is of interest to the human but not to the dog. Communicating with a helpful motive is particularly interesting because it might suggest that dogs understand the human's goals and need for information. In study 1, we assessed whether dogs would abandon an object that they find interesting in favour of an object useful for their human partner, a random novel distractor, or an empty container. Results showed that it was mainly self-interest that was driving the dogs' behaviour. The dogs mainly directed their behaviour towards the object they had an interest in, but dogs were more persistent when showing the object relevant to the human, suggesting that to some extent they took the humans interest into account. Another possibility is that dogs' behaviour was driven by an egocentric motivation to interact with novel targets and that the dogs' neophila might have masked their helpful tendencies. Therefore, in study 2 the dogs had initial access to both objects, and were expected to indicate only one (relevant or distractor. The human partner interacted with the dog using vocal communication in half of the trials, and remaining silent in the other half. Dogs from both experimental groups, i.e. indicating the relevant object or indicating the distractor, established joint attention with the human. However, the human's vocal communication and the

In veterinary medicine, Staphylococcus schleiferi was previously assumed to be an inhabitant of carnivore skin, however, more recently, it has been repeatedly documented in the literature as both an inhabitant and as a pathogen. In order to determine the frequency of nasal carriage, and the methicillin susceptibility pattern of S. schleiferi from healthy dogs as well as dogs with otitis and/or pyoderma, a prospective study including 24 dogs with healthy ears and skin, 27 dogs with healthy ears and pyoderma, 15 dogs with otitis without pyoderma and 20 dogs with both otitis and pyoderma was performed. Specimens were obtained and cultured and isolates were identified as S. schleiferi based on growth and biochemical characteristics. S. schleiferi was isolated from the nares of 1 healthy dog, 3 dogs with recurrent pyoderma, 2 dogs with recurrent otitis, and 1 dog with both recurrent otitis and pyoderma. One of the S. schleiferi isolates was methicillin resistant. Nasal carriage of S. schleiferi does occur in healthy dogs as well as dogs with otitis and pyoderma. Methicillin resistant and sensitive S. schleiferi can be found in the nares of dogs with diseased ears and skin. Copyright © 2012 Elsevier B.V. All rights reserved.

Demography and dog-human relationships of the dog population in Zimbabwean communal lands.

Dogs are Zimbabwe's primary vector for rabies, and the majority live in communal lands (traditional agropastoralist rural areas). In 1994, a household questionnaire survey was conducted to provide baseline data on the demography and dog-human relationships of the dogs in the communal lands. The survey showed that all the dogs were owned, and there was no evidence of a feral population. They were unrestricted and semi-dependent on people. The numbers of dogs per capita varied little in each communal land, resulting in higher dog densities in communal lands with higher human densities, and indicating that people were not intolerant of dogs at higher densities. The population turnover was rapid: the life expectancy of the dogs was 1.1 years, the mean age 2.0 years, and 71.8 per cent died in their first year. The population was heavily skewed towards juveniles, with 40.8 per cent aged less than 12 months. Despite the high juvenile mortality, the population was growing by 6.52 per cent per annum. It was estimated that in 1994 there were 1.36 million dogs in communal lands.

Bronchiectasis is an irreversible dilatation of the bronchi resulting from chronic airway inflammation. In people, computed tomography (CT) has been described as the noninvasive gold standard for diagnosing bronchiectasis. In dogs, normal CT bronchoarterial ratios have been described as qualitative CT characteristics of bronchiectasis in a cohort of dogs with confirmed disease. Inclusion criteria for the study were thoracic radiography, thoracic CT, and a diagnosis of bronchiectasis based on bronchoscopy and/or histopathology. For each included dog, a single observer measured CT bronchoarterial ratios at 6 lobar locations. Qualitative thoracic radiography and CT characteristics were recorded by consensus opinion of two board-certified veterinary radiologists. Twelve dogs met inclusion criteria. The mean bronchoarterial ratio from 28 bronchiectatic lung lobes was 2.71 ± 0.80 (range 1.4 to 4.33), and 23/28 measurements were >2.0. Averaged bronchoarterial ratios from bronchiectatic lung lobes were significantly larger (P Qualitative CT characteristics of bronchiectasis included lack of peripheral airway tapering (12/12), lobar consolidation (11/12), bronchial wall thickening (7/12), and bronchial lumen occlusion (4/12). Radiographs detected lack of airway tapering in 7/12 dogs. In conclusion, the most common CT characteristics of bronchiectasis were dilatation, a lack of peripheral airway tapering, and lobar consolidation. Lack of peripheral airway tapering was not visible in thoracic radiographs for some dogs. For some affected dogs, bronchoarterial ratios were less than published normal values. © 2013 Veterinary Radiology & Ultrasound.

To describe the operative technique and perioperative outcome for laparoscopic-assisted splenectomy (LAS) in dogs. Retrospective case series. 18 client-owned dogs. Medical records of dogs with naturally occurring disease of the spleen treated by means of LAS between 2012 and 2014 were reviewed. History, signalment, results of physical examination, results of preoperative diagnostic testing, details of surgical technique, intraoperative findings including results of abdominal exploration and staging, concurrent surgical procedures, complications, histopathologic diagnoses, duration of postoperative hospitalization, and perioperative outcome were recorded. The perioperative period was defined as the time from hospital admission for LAS until discharge or death (within the same visit). All dogs underwent initial abdominal exploration and staging via multiple 5-mm laparoscopic ports (n = 2) or a single commercially available multichannel port (16), followed by minilaparotomy with insertion of a wound retraction device, progressive exteriorization of the spleen, sealing of hilar vessels, and splenectomy. Splenectomy was performed for treatment of a splenic mass (n = 15), suspected neoplasia (2), or refractory immune-mediated disease (1). Median size (width × length) of splenic masses was 5 × 5 cm (range, 1.6 to 11.0 cm × 1.5 to 14.5 cm). Complications were limited to minor intraoperative hemorrhage in 1 dog; no patient required conversion to open laparotomy. Results indicated that LAS was technically feasible in dogs and not associated with major complications. Further evaluation is required; however, in appropriately selected patients, LAS may offer the benefits of a minimally invasive technique, including a smaller incision and improved illumination and magnification during exploration and staging.

Mortality because of neoplasia was examined in Segment III dogs exposed to 0,20, or 100 R of 60 Co gamma radiation in prenatal and early postnatal life. During the inital 10 years of the experiment (through January 31, 1978) 20 dogs died or were killed because of neoplasia, 19 having been irradiated. Tumors in these 19 irradiated dogs included 5 malignant lymphomas, 8 carcinomas (2 of mammary origin, 2 of prostatic origin, and 1 each or oral mucosa, ovary, urinary bladder, and thyroid origin), 4 sarcomas (2 hemangiosarcomas, 1 fibrosarcoma and 1 mast cell sarcoma), 1 astrocytoma, and 1 hepatocellular adenoma. Neoplasms occurred in all irradiated groups except 8 dpc (20 and 100R) and 70 dpp (100R). Eleven neoplasms developed in dogs irradiated perinatally (55 dpc or 2 dpp) with 20 or 100R. Four of the tumors in the perinatally irradiated dogs were detected before 2 years of age. The earliest death was at 3 months, because of an astrocytoma. A single sham-irradiated dog died or a malignant tumor, a mammary carcinoma. Preliminary analyses point to three findings of particular interest: the preponderance of neoplasms causing death or euthanasia occurred in irradiated dogs, the unusual finding of four deaths because of neoplasia prior to 2 years of age in perinatally irradiated dogs, and the occurrence of five malignant lymphomas in this relatively small irradiated population

1987-01-01

Radiation-induced bone tumors in beagle dogs exposed to 90 Sr have been evaluated in terms of their incidence, time of appearance, occurrence as multiple tumors, anatomic distribution, and the influence of sex on their development. Among dogs fed 90 Sr during skeletal development, the incidence of bone tumors was dose independent. Tumors thus appeared in 10 of 19 dogs receiving average skeletal doses of 130 Gy, 15 of 60 receiving 97 Gy, 5 of 61 receiving 61 Gy, 2 of 65 receiving 26 Gy, and 1 of 40 receiving 1.3 Gy. No tumors appeared among 66 dogs who received 8 Gy, 78 who received 0.3 Gy, and 80 non-irradiated controls, all of which have been observed for life. Among dogs given a single inravenous injection of 90 Sr in early adulthood, tumor production was somewhat higher than among 90 Sr-fed dogs at the same radiation dose: bone tumors were present in 6 of 25 dogs who received 62 Gy and 1 of 20 dogs who received 7.5 Gy. Bone tumors appeared sooner and were more often multiple in animals receiving the higher doses. Long bones were the sites of most of the tumors appearing after the highest dose level. Bones of the head, particularly the mandible, were the predominant site of tumors in the next highest dose level group. (orig.)

2012-01-01

This article reports the first known study on dogs in Port-au-Prince. Interviews with 1,290 residents provided information on 1,804 dogs. More than 57.7% of homes kept dogs. Not all the dogs received vaccinations for rabies (41.6%), even though 28.2% of households had had a household member bitten by a dog. Although the "owned" dog population had decreased as a result of the earthquake in January 2010, the number of roaming dogs appeared to have been uninfluenced by the disaster. Given that 64.8% of dogs probably had access to the street and only 6.0% of the females were spayed, to humanely contain the dog population will require both confinement and neutering. Although roaming dogs were considered a nuisance by 63.3% of respondents, 42.6% of households fed dogs they did not own.

Evaluation of dogs with elevated plasma thyroxine concentration fed raw food before and after changing the diet. Between 2006 and 2011 all dogs presented with an elevated plasma thyroxine concentration and a dietary history of feeding raw food were included. Thyroxine (reference interval: 19·3 to 51·5 nmol/L) and in many cases also thyroid-stimulating hormone concentrations (reference interval: weight loss, aggressiveness, tachycardia, panting and restlessness while six dogs had no clinical signs. After changing the diet eight dogs were examined: thyroxine concentration normalised in all dogs and clinical signs resolved. Dietary hyperthyroidism can be seen in dogs on a raw meat diet or fed fresh or dried gullets. Increased plasma thyroxine concentration in a dog, either with or without signs of hyperthyroidism, should prompt the veterinarian to obtain a thorough dietary history. © 2012 British Small Animal Veterinary Association.

Splenitis is uncommonly reported in dogs. Herein, the authors describe its prevalence, clinical findings and outcomes, histologic patterns, and causes. Splenic samples of dogs diagnosed with splenitis between 2005 and 2013 were collected and stained with hematoxylin and eosin, Gram, green-Gram, Giemsa, periodic acid-Schiff, and Ziehl-Neelsen. Samples were processed for polymerase chain reaction (PCR) to detect bacteria, fungi, and protozoa ( Leishmania infantum, Hepatozoon canis). Thirty-three of 660 splenic samples (5%) had splenitis. Clinical findings and outcomes were available in 19 dogs (58%); 49% had weakness, 33% had fever, and 84% survived. The most frequent inflammatory patterns included purulent splenitis (27%), pyogranulomatous splenitis (24%), and neutrophilic perisplenitis (15%). One dog had a putative diagnosis of primary splenitis; in 8 dogs, microorganisms were identified histologically or by PCR in the spleen without obvious comorbidities. Twenty-four dogs (73%) had concurrent diseases; a permissive role in the development of splenitis was suspected in 21 of these cases. Histologic examination identified the cause of splenitis in 10 dogs. Bacteria were identified by PCR in 23 cases, but the bacteria were confirmed histologically in only 6 of these. Leishmania was detected with PCR in 6 dogs. Leishmania was identified in 1 dog and H. canis in another histologically, but both were PCR negative. Fungi were identified in 8 spleens by PCR and in 1 by histology. This study suggests that splenitis is uncommon in dogs and is frequently associated with systemic diseases. Prognosis is favorable in most cases. Identification of bacteria, fungi, and protozoa in the spleens of affected dogs with PCR should be interpreted cautiously, because the findings are not confirmed histologically in many cases.

Although Indonesia has been rabies-infected since at least the 1880s, some islands remain rabies-free, such as Lombok. However, due to its adjacency to rabies-infected islands such as Bali and Flores, there is considerable risk of a rabies incursion. As part of a rabies risk assessment project, surveys were conducted to estimate the size of the dog population and to describe dog management practices of households belonging to different ethnic groups. A photographic-recapture method was employed and the number of unowned dogs was estimated. A total of 400 dog owning households were interviewed, 300 at an urban site and 100 at a rural site. The majority of the interviewed households belonged to the Balinese ethnic group. Owned dogs were more likely male, and non-pedigree or local breed. These households kept their dogs either fully restricted, semi-free roaming or free-roaming but full restriction was reported only at the urban site. Dog bite cases were reported to be higher at the urban site, and commonly affected children/young adults to 20 years old and males. A higher number of unowned dogs was observed at the urban site than at the rural site. Data generated within these surveys can inform rabies risk assessment models to quantify the probability of rabies being released into Lombok and resulting in the infection of the local dog population. The information gained is critical for efforts to educate dog owners about rabies, as a component of preparedness to prevent the establishment of rabies should an incursion occur. PMID:25932916

Previously the authors reported on a Hybrid Artificial Pancreas device that maintained patent vascular anastomoses in normal dogs and, when seeded with allogeneic canine islets, maintained normal fasting blood sugars (FBS) in diabetic pancreatectomized dogs. Eventual failure of these devices was believed to be related to loss of islet viability and/or insufficient islet mass. The current study evaluates the effect of increased islet mass produced by implantation of two islet-seeded devices in pancreatectomized dogs and compares the results with those from dogs that received a single device. Twelve of fifteen dogs receiving single devices showed initial function as determined by elimination or reduction of exogenous insulin requirement; four showed initial function and seven showed extended function (100 to 284 days). Excessive weight loss (more than 20%), despite normal FBS and insulin dependence, required that four animals in this latter group be killed. Devices seeded with xenogeneic islets have met with limited success. One dog that received two bovine islet-seeded devices achieved function for more than 100 days; the remaining bovine-seeded devices (n = 8) functioned for only 3 to 16 days. Porcine islet-seeded devices were assessed by intravenous glucose tolerance tests (IVGTT). Recipients of two devices seeded with allogeneic islets demonstrated improved IVGTT results when compared to those from pancreatectomized dogs and recipients of single devices but were abnormal when compared to intact animals. Histologic examination of device and autopsy material from all failed experiments was performed and showed no mononuclear cell infiltration of the islet chamber or vascular graft material, only a few incidence of device thrombosis, and varying degrees of islet viability as judged by morphologic and immunohistochemical evaluation. The authors believe they have demonstrated progress toward the development and clinical applicability of the Hybrid Artificial Pancreas

The Academy of Nutrition and Dietetics (the Academy) and the American Society for Parenteral and Enteral Nutrition (A.S.P.E.N.), utilizing an evidence-informed, consensus-derived process, recommend that a standardized set of diagnostic indicators be used to identify and document pediatric malnutrition (undernutrition) in routine clinical practice. The recommended indicators include z scores for weight-for-height/length, body mass index-for-age, or length/height-for-age or mid-upper arm circumference when a single data point is available. When 2 or more data points are available, indicators may also include weight gain velocity (nutritional risk is not the purpose of this paper. Clinicians should use as many data points as available to identify and document the presence of malnutrition. The universal use of a single set of diagnostic parameters will expedite the recognition of pediatric undernutrition, lead to the development of more accurate estimates of its prevalence and incidence, direct interventions, and promote improved outcomes. A standardized diagnostic approach will also inform the prediction of the human and financial responsibilities and costs associated with the prevention and treatment of undernutrition in this vulnerable population and help to further ensure the provision of high-quality, cost-effective nutritional care. © 2014 American Society for Parenteral and Enteral Nutrition and Academy of Nutrition and Dietetics.

Objective: To evaluate the biological effects of Beagle dogs irradiated by γ-rays at different doses. Methods: All Beagle dogs were divided into six groups and were subjected respectively to total-body irradiation (TBI) with a single dose of 6.5, 5.5, 5.0, 4.5, 3, 5 and 2.5 Gy γ-rays delivered by 60 Co sources at 7.224 x 10 -2 C/kg per minute. The general condition, blood cell counts and bone marrow cell CFC assays were observed. Results: Vomiting occurred at 0.5 to 2 hours after TBI in all groups. In 6.5 Gy group 3/5 dogs had blood-watery stool and 1/5 in 5.5 Gy group had watery stool. Diarrhea occurred in all other animals. Only one dog in 2.5 Gy group survived, all of others died. in order of decreasing irradiation dosage, the average survival time was 5.0, 8.0, 9.3, 9.5, 10.5 and 14.1 days, respectively. Conclusions: According to the clinical symptoms, leukocyte count and survival time of the dogs, the irradiation dose which will induce very severe hematopoietic radiation syndrome in Beagle dogs is 4.5 to 5.0 Gy

Parenteral nutrition (PN) has become essential in the management of sick and growing newborn populations in the NICU. In the past few decades, PN has become fundamental in the nutritional management of the very low birth weight infant (macronutrients in PN, including carbohydrates, protein, and fat. A subsequent article will review the micronutrients in PN, including electrolytes, minerals, and vitamins.

Full Text Available Necrotizing meningoencephalitis (NME affects toy and small breed dogs causing progressive, often fatal, inflammation and necrosis in the brain. Genetic risk loci for NME previously were identified in pug dogs, particularly associated with the dog leukocyte antigen (DLA class II complex on chromosome 12, but have not been investigated in other susceptible breeds. We sought to evaluate Maltese and Chihuahua dogs, in addition to pug dogs, to identify novel or shared genetic risk factors for NME development. Genome-wide association testing of single nucleotide polymorphisms (SNPs in Maltese dogs with NME identified 2 regions of genome-wide significance on chromosomes 4 (chr4:74522353T>A, p = 8.1×10-7 and 15 (chr15:53338796A>G, p = 1.5×10-7. Haplotype analysis and fine-mapping suggests that ILR7 and FBXW7, respectively, both important for regulation of immune system function, could be the underlying associated genes. Further evaluation of these regions and the previously identified DLA II locus across all three breeds, revealed an enrichment of nominal significant SNPs associated with chromosome 15 in pug dogs and DLA II in Maltese and Chihuahua dogs. Meta-analysis confirmed effect sizes the same direction in all three breeds for both the chromosome 15 and DLA II loci (p = 8.6×10-11 and p = 2.5×10-7, respectively. This suggests a shared genetic background exists between all breeds and confers susceptibility to NME, but effect sizes might be different among breeds. In conclusion, we identified the first genetic risk factors for NME development in the Maltese, chromosome 4 and chromosome 15, and provide evidence for a shared genetic risk between breeds associated with chromosome 15 and DLA II. Last, DLA II and IL7R both have been implicated in human inflammatory diseases of the central nervous system such as multiple sclerosis, suggesting that similar pharmacotherapeutic targets across species should be investigated.

Between May and July 1987, we studied 36 children with second or third degree dehydration secondary to acute diarrheal disease of less than one week duration; they had no serious associated problems. Parenteral rehydration was carried out with a solution similar in composition to the one recommended by the World Health Organization for Oral Rehydration Therapy (ORT. Rehydration was achieved in 30 patients within 6 hours and In 3 more within 12 hours; there were no cases of hypernatremia or hyperkalemia. It is concluded that parenteral rehydration with a solution similar to the one employed for ORT is an adequate alternative when oral rehydration is not indicated in children with diarrheal disease.

Entre mayo y julio de 1987 se estudiaron 36 niños que ingresaron al Hospital Infantil de Medellín con deshidratación de segundo o tercer grado, secundaria a enfermedad diarreica de evolución menor de una semana y sin enfermedad grave asociada. La hidratación se llevó a cabo parenteralmente empleando una mezcla de composición similar a la que recomienda la Organización Mundial de la Salud para la Terapia de Rehidratación Oral (TRO. Se logró la hidratación en un lapso de 6 horas en 30 de los 36 pacientes y en 3 más en las siguientes 6 horas; no se produjeron casos de hipernatremia ni de hiperkalemia. Se concluye que la hidratación parenteral, con una solución de composición similar a la de la TRO, es una alternativa adecuada cuando no está indicada la hidratación oral del niño con enfermedad diarreica.

Full Text Available Abstract Background Research on the uptake and transport of astaxanthin is lacking in most species. We studied the uptake of astaxanthin by plasma, lipoproteins and leukocytes in domestic dogs and cats. Methods Mature female Beagle dogs (18 to 19 mo old; 11 to 14 kg BW were dosed orally with 0, 0.1, 0.5, 2.5, 10 or 40 mg astaxanthin and blood taken at 0, 3, 6, 9, 12, 18 and 24 h post-administration (n = 8/treatment. Similarly, mature domestic short hair cats (12 mo old; 3 to 3.5 kg body weight were fed a single dose of 0, 0.02, 0.08, 0.4, 2, 5, or 10 mg astaxanthin and blood taken (n = 8/treatment at the same interval. Results Both dogs and cats showed similar biokinetic profiles. Maximal astaxanthin concentration in plasma was approximately 0.14 μmol/L in both species, and was observed at 6 h post-dosing. The plasma astaxanthin elimination half-life was 9 to 18 h. Astaxanthin was still detectable by 24 h in both species. In a subsequent study, dogs and cats were fed similar doses of astaxanthin daily for 15 to 16 d and astaxanthin uptake by plasma, lipoproteins, and leukocytes studied. In both species, plasma astaxanthin concentrations generally continued to increase through d 15 or 16 of supplementation. The astaxanthin was mainly associated with high density lipoprotein (HDL. In blood leukocytes, approximately half of the total astaxanthin was found in the mitochondria, with significant amounts also associated with the microsomes and nuclei. Conclusion Dogs and cats absorb astaxanthin from the diet. In the blood, the astaxanthin is mainly associated with HDL, and is taken up by blood leukocytes, where it is distributed to all subcellular organelles. Certain aspects of the biokinetic uptake of astaxanthin in dogs and cats are similar to that in humans.

Full Text Available Organophosphate (OP poisoning is common in India. Only few case reports of parenteral OP poisoning have been described. We report a case of self-injected methyl parathion poisoning, presenting after four days with seizure, altered sensorium, and respiratory distress which posed a diagnostic and therapeutic dilemma. Despite nonavailability of history of OP poisoning, he was treated based on suspicion and showed a good clinical response to treatment trial with atropine and pralidoxime, and had a successful recovery. Atypical presentations may be encountered following parenteral administration of OP poison, and even a slight suspicion of this warrants proper investigations and treatment for a favorable outcome. Persistently low plasma cholinesterase level is a useful marker for making the diagnosis.

INTRODUCTION: Parenteral nutrition-associated cholestasis (PNAC) is a complication of long-term parenteral nutrition (PN). Removal of lipids may reverse PNAC but compromises the energy to ensure infant growth. The purpose of this study was to test whether a low-fat, high-carbohydrate PN regimen......, which prevents and reverses PNAC in adults, could do the same in infants. This regimen could potentially avoid the problem of diminished energy input after removing nutritional lipids. METHODS: Infants developing PNAC over a 2-year period were started on a low-fat PN regimen with calories primarily from...

Canine inflammatory mammary carcinoma (IMC) is a rare, locally aggressive, highly metastatic tumor that is poorly responsive to treatment. The purposes of this study were to retrospectively evaluate the history, signalment, and clinical signs of dogs with IMC; compare the outcome of affected dogs treated with traditional chemotherapy with those treated with piroxicam; evaluate Cox-2 expression of IMC cells; and correlate Cox-2 expression with outcome based on treatment. Strong cyclooxygenase-2 expression was present in all tumors. Improvement in clinical condition and disease stability was achieved in all dogs treated with piroxicam, with mean and median progression-free survival of 171 and 183 days, respectively. Median survival time of 3 dogs treated with doxorubicin-based protocols was 7 days, which was significantly less than that of dogs treated with piroxicam (median, 185 days). In conclusion, piroxicam should be considered as a single agent for the treatment of dogs with inflammatory mammary carcinoma. PMID:19436636

In this study the safety and protective immunity of an oral rabies vaccine, based on the live, modified rabies virus strain VRC-RZ2, was examined in stray dogs (Canis Sp.), corsacs (Vulpes corsac) and steppe wolves (Canis lupus campestris). In the safety group (dogs, n=6; corsacs, n=3; wolves, n=3) which was vaccinated with a 10-times field dose/animal, no animals showed any signs of disease or changes in behavior or appetite during the period of clinical observation, similar to the animals in the negative control group. Saliva samples taken from animals prior and post (5 th and 10 th days) vaccination failed to demonstrate rabies virus antigen. Observations of immunogenicity in vaccinated carnivores (dogs, corsacs and wolves) during a 180 day period showed the titers of virus neutralizing antibodies (VNA) in the blood sera of vaccinated dogs to be within 0.59-1.37 IU/mL. On 14 days post vaccination (dpv), all the wild carnivores had detectable levels of neutralizing antibodies, with mean titers ranging from 0.50 ± 0.07 IU/mL (for wolves) to 0.59 ± 0.10 IU/mL (for corsacs). Weeks after vaccination, all the vaccinated wolves and corsacs had higher levels of neutralizing antibodies: 0.70 ± 0.10 - 0.71 ± 0.08 IU/mL at 30 dpv, 1.06 ± 0.08 - 1.28 ± 0.21 IU/mL at 60 dpv and 0.41 ± 0.09 - 047 ± 0.06 at 180 dpv. The highest level of VNA (˃1.0 IU/ml) was detected at 60 dpv, in all vaccinated animals. After challenge all vaccinated dogs remained healthy for 180 days. Control animals (unvaccinated dogs) developed symptoms of rabies on day 6 post administration of a virulent virus and died of rabies on days 11-13. Of note, the VNA titers in all the wild carnivores (corsacs and wolves) immunized with VRC-RZ2 were higher than 0.5 IU/ml (0.59 ± 0.11 IU/ml), even as early as 14 days post vaccination. These, presumably protective, titers of antibodies to rabies virus were present in the dogs and wild carnivores examined in this study for at

The incidence and causes of metabolic alkalosis in dogs and cats have not been fully investigated. To describe the incidence, nature, and etiology of metabolic alkalosis in dogs and cats undergoing blood gas analysis at a veterinary teaching hospital. Dogs and cats at a veterinary medical teaching hospital. Acid-base and electrolyte results for dogs and cats measured during a 13-month period were retrospectively collected from a computer database. Only the first measured (venous or arterial) blood gas analyzed in a single hospitalization period was included. Animals with a base excess above the reference range for the species were included. A total of 1,805 dogs and cats were included. Of these, 349 (19%) were identified as having an increased standardized base excess, 319 dogs and 30 cats. The mixed acid-base disorder of metabolic alkalosis with respiratory acidosis was the most common abnormality identified in both dogs and cats. Hypokalemia and hypochloremia were more common in animals with metabolic alkalosis compared to animals without metabolic alkalosis. The 4 most commonly identified underlying diseases were respiratory disease, gastrointestinal tract obstruction, furosemide administration, and renal disease. Metabolic alkalosis was less common than metabolic acidosis in the same population of animals. Evidence of contraction alkalosis was present in many patients in this study. Hypokalemia and hypochloremia were more frequent in patients with metabolic alkalosis and suggest the importance of evaluation of acid-base status in conjunction with serum electrolyte concentrations.

Onchocerca lupi (Spirurida, Onchocercidae) is an emerging vector-borne helminth that causes nodular lesions associated with acute or chronic ocular disease in dogs and cats. Since its first description in dogs in 1991, this zoonotic filarioid has been increasingly reported in Europe and the United States. An 8-year-old outdoor mixed-breed female dog from the Algarve (southern Portugal) was presented with a history of severe dyspnoea. Cervical and thoracic radiographs revealed a slight reduction in the diameter of the cervical trachea and a moderate increase in radiopacity of the laryngeal soft tissue. An exploratory laryngoscopy was performed, revealing filiform worms associated with stenosis of the thyroid cartilage and a purulent necrotic tissue in the larynx lumen. A single sessile nodule, protruding from the dorsal wall of the laryngeal lumen caused a severe reduction of the glottis and tracheal diameter. Fragments of the worms were morphologically and molecularly identified as O. lupi. Histological examination of the nodule showed a granulomatous reaction with sections of coiled gravid female nematodes. Following laryngoscopy, a tracheostomy tube was inserted to relieve dyspnoea and ivermectin (300 μg/kg, once a week, for 8 weeks) combined with prednisolone was prescribed. The dog showed a complete recovery. Although O. lupi has been isolated in human patients from the spinal cord, this is the first report of an aberrant migration of O. lupi in a dog. The veterinary medical community should pay attention to aberrant location of O. lupi and consider onchocercosis as a differential diagnosis for airway obstruction in dogs.
