Anorexia in cats is often encountered in practice. In many cases, the underlying cause is not readily apparent. In this situation, the aetiology of the anorexia must be determined by a methodical step-wise investigation. In addition, measures must be taken to address the anorexia to prevent detrimental metabolic consequences. This article explains how to approach the diagnosis and management of anorexia in cats.

Objective To review the clinical use of a lipid-free, ready-made amino acid and glucose parenteral nutrition ( PN) solution in dogs. Design Retrospective study of dogs from 2006 to 2012 that received this form of PN. Setting University veterinary teaching hospital. Animals Seventy dogs presented to the hospital for treatment of various diseases in which PN was used as part of patient management. Dogs were administered PN at the discretion of the primary clinician. Intervention A lipid-free, ready-made solution containing amino acid (59 g/L) and dextrose (100 g/L) was administered intravenously as a constant rate infusion to provide nutritional support. Measurements and Main Results PN was provided for a median of 2.2 days (range 0.5-9.5 days) in the 70 dogs, totaling 168 days of PN. The PN provided a median of 5.5 g/100 kcal of protein (range 1-9.5 g/100 kcal) and a median of 2.2 mg/kg of bodyweight per minute (range 0.8-5.2 mg/kg/min) of glucose, which reflected a median of 57% of the resting energy requirement (range 9-100%). Metabolic complications developed in 43 of 67 dogs where these data were recorded, but the development of hyperkalemia was the only complication associated with a poor outcome (eg, death or euthanasia). Mechanical complications were seen in 28 dogs, and all but one of these occurred when PN was delivered through peripheral catheters. Septic complications were confirmed in 5 dogs. Conclusions This form of PN is suitable for clinical use and can provide both protein and calories to ill dogs. It was, however, associated with a high rate of complications and requires careful patient monitoring. [ABSTRACT FROM AUTHOR]

MALNUTRITION is thought to have a significant impact on morbidity and mortality in human patients who are critically ill. As a result, nutritional support has become a priority rather than an afterthought in the management of patients in many intensive care units. The importance of nutritional modulation of diseases is also increasingly being recognised in veterinary medicine, and this is especially true of critical illness. This article discusses the provision of parenteral and enteral nutrition for the critical care patient, and describes some situations in which these treatments are particularly useful.

Background: After a strong epidemiological link to diet was established in an outbreak of pancytopenia in cats in spring 2021 in the United Kingdom, 3 dry diets were recalled. Concentrations of the hemato‐ and myelotoxic mycotoxins T‐2, HT‐2 and diacetoxyscirpenol (DAS) greater than the European Commission guidance for dry cat foods were detected in the recalled diets. Objectives: To describe clinical and clinicopathological findings in cats diagnosed with suspected diet induced pancytopenia. Animals: Fifty cats presenting with pancytopenia after exposure to a recalled diet. Methods: Multicenter retrospective case series study. Cats with known exposure to 1 of the recalled diets were included if presented with bi‐ or pancytopenia and underwent bone marrow examination. Results: Case fatality rate was 78%. Bone marrow aspirates and biopsy examination results were available in 23 cats; 19 cats had a bone marrow aspirate, and 8 cats had a biopsy core, available for examination. Bone marrow hypo to aplasia—often affecting all cell lines—was the main feature in all 31 available core specimens. A disproportionately pronounced effect on myeloid and megakaryocytic cells was observed in 19 cats. Myelofibrosis or bone marrow necrosis was not a feature. Conclusion and Clinical Importance: Mycotoxin induced pancytopenia should be considered as differential diagnosis in otherwise healthy cats presenting with bi‐ or pancytopenia and bone marrow hypo‐ to aplasia.

A letter to the editor is presented which discusses a study being conducted on the sterile neutrophilic-macrophagic lymphadenitis in the English springer spaniel, aimed at describing the history, clinical signs, and clinicopathological abnormalities of the condition.
