Radioiodine treatment in hyperthyroid cats : insights into the characteristics of owners and their cats, and owner motivation and perceptions

ObjectivesRadioiodine (I-131) therapy is the most appropriate treatment option for many hyperthyroid cats, as it is minimally invasive and often curative. Nevertheless, I-131 treatment is not always pursued by owners. Hence, it is important to obtain more insight into owner satisfaction during and after I-131 treatment, and their decision-making process. In this study, we describe the characteristics of owners and their hyperthyroid cats referred for I-131 therapy, and determine owners' motivation and how they experienced the I-131 treatment of their cat. MethodsA survey was sent to owners whose cats underwent I-131 therapy (n = 1071) between 2010 and 2017 at Ghent University. The survey contained 35 questions with tick-box or free-text answer options concerning family situation, pet insurance, previous therapy, comorbidities, motivation for I-131 therapy and owner perception of this treatment. ResultsIn total, 438 owners completed 94% or more of the questionnaire. Over half of the cats (55%) had received previous medical, dietary or surgical treatment. Motivations for changing the initial therapy to I-131 therapy included difficulties in administering medication (31%), insufficient improvement in clinical signs (23%), side effects (16%) and following the referring veterinarian's advice (16%). Almost a fifth of owners (18%) were not informed about the existence of I-131 therapy by their veterinarian and found information on I-131 treatment online or through friends. Hospitalising their cat was very distressing for 17% of owners. Most owners (92%) were satisfied with the treatment. Reasons for dissatisfaction were insufficient communication, iatrogenic hypothyroidism, persistent hyperthyroidism and comorbidities post-treatment. Conclusions and relevanceOur study stresses the importance of communication regarding the possible outcome of I-131 treatment, the importance of managing underlying comorbidities before treatment and anticipating the stress of owners during their cat's hospitalisation period. The results of this study could help in improving client communication when advising on I-131 treatment

Do Antibiotics Reduce the Incidence of Infections After Percutaneous Endoscopic Gastrostomy Placement in Children?

OBJECTIVE: Percutaneous endoscopic gastrostomy (PEG) provides a long-term solution for tube dependency. Pediatric guidelines recommend prophylactic antibiotic treatment (ABT) based on adult studies. AIM: To compare wound infection and other complications in children receiving a PEG with and without prophylactic ABT. METHODS: Retrospective study including children 0 to 18 years undergoing PEG placement. Patients with (2010-2013) and without (2000-2010) ABT were compared with respect to the occurrence of wound infection and other complications. RESULTS: In total, 297 patients were included (median age 2.9 years, 53% boys). Patients receiving ABT per PEG protocol (n = 78) had a similar wound infection rate (17.9% vs 21%, P = 0.625), significantly less fever (3.8% vs 14.6%, P = 0.013), leakage (0% vs 9.1%, P = 0.003) and shorter hospital admission (2 vs 4 days, P = 0.000), but more overgranulation (28.2% vs 8.7%, P = 0.000) compared with those without (n = 219). Patients receiving any ABT, per PEG protocol or clinical indication (n = 115), had similar occurrence of wound infection (19.1% vs 20.9%, P = 0.768), fever (7.8% vs 14.3%, P = 0.100) and leakage (3.5% vs 8.8%, P = 0.096), a significantly shorter hospital admission (3 vs 4 days, P = 0.000), but more overgranulation (21.7% vs 8.8%, P =0.003) compared with those without (n = 182). CONCLUSIONS: Prophylactic ABT does not seem to reduce the occurrence of wound infection but it might be beneficial with respect to fever, leakage and duration of hospital admission, but not overgranulation. A randomized controlled trial is needed to confirm our results

Developmental and Wound-, Cold-, Desiccation-, Ultraviolet-B-Stress-Induced Modulations in the Expression of the Petunia Zinc Finger Transcription Factor Gene ZPT2-2

The ZPT2-2 gene belongs to the EPF gene family in petunia (Petunia hybrida), which encodes proteins with TFIIIA-type zinc-finger DNA-binding motifs. To elucidate a possible function for ZPT2-2, we analyzed its pattern of expression in relation to different developmental and physiological stress signals. The activity of the ZPT2-2 promoter was analyzed using a firefly luciferase (LUC) reporter gene, allowing for continuous measurements of transgene activity in planta. We show that ZPT2-2::LUC is active in all plant tissues, but is strongly modulated in cotyledons upon germination, in leaves in response to desiccation, cold treatment, wounding, or ultraviolet-B light, and in petal tissue in response to pollination of the stigma. Analysis of mRNA levels indicated that the modulations in ZPT2-2::LUC expression reflect modulations in endogenous ZPT2-2 gene expression. The change in ZPT2-2::LUC activity by cold treatment, wounding, desiccation, and ultraviolet-B light suggest that the phytohormones ethylene and jasmonic acid are involved in regulating the expression of ZPT2-2. Although up-regulation of expression of ZPT2-2 can be blocked by inhibitors of ethylene perception, expression in plants is not induced by exogenously applied ethylene. The application of jasmonic acid does result in an up-regulation of gene activity and, thus, ZPT2-2 may play a role in the realization of the jasmonic acid hormonal responses in petunia
