“…One of the main strategies used by microorganisms to escape this macrophage activity involves altering the response profile of macrophages. 185,[235][236][237][238][239][240][241][242][243][244][245][246][247][248][249][250][251][252] The activation of a response profile mediated by M1 macrophages is commonly associated with a protective tissue environment and has been described for infections by pathogens such as Helicobacter pylori, M. tuberculosis, Mycobacterium leprae, Salmonella typhi, and Chlamydia. [253][254][255][256][257][258] M1 macrophages elicit an effective immune response against S. typhi and H. pylori, and in the response against H. pylori, the induction of iNOS associated with the M1 profile is closely related to the occurrence of gastric cancer.…”

Macrophages are a functionally heterogeneous group of cells with specialized functions depending not only on their subgroup but also on the function of the organ or tissue in which the cells are located. The concept of macrophage phenotypic heterogeneity has been investigated since the 1980s, and more recent studies have identified a diverse spectrum of phenotypic subpopulations. Several types of macrophages play a central role in the response to infectious agents and, along with other components of the immune system, determine the clinical outcome of major infectious diseases. Here, we review the functions of various macrophage phenotypic subpopulations, the concept of macrophage polarization, and the influence of these cells on the evolution of infections. In addition, we emphasize their role in the immune response in vivo and in situ, as well as the molecular effectors and signaling mechanisms used by these cells. Furthermore, we highlight the mechanisms of immune evasion triggered by infectious agents to counter the actions of macrophages and their consequences. Our aim here is to provide an overview of the role of macrophages in the pathogenesis of critical transmissible diseases and discuss how elucidation of this relationship could enhance our understanding of the host–pathogen association in organ-specific immune responses.

“…Fluid therapy is a major advance in the treatment of colic , although the delivery volumes and rates selected in veterinary medicine tend to be arbitrary and most published guidelines lack scientific support . There is some evidence that overhydration with sodium‐rich crystalloids could be potentially harmful in human patients and could reduce colloid osmotic pressure to levels associated with decreased survival in horses .…”

Fifty years of colic surgery

Colic surgery is one of few treatments in which a veterinarian can use a skill to save an animal's life from a deadly disease within a short timeframe. Unfortunately, such success is not achieved without considerable risk for surgical failure, which is responsible for most complications in the immediate post-operative period. The last 50 years have witnessed considerable improvements in colic surgery, although a ranking of the most important ones might not meet with universal agreement. Teamwork plays a critical role in the final outcome, starting and finishing with the referring veterinarian and owner. These individuals are responsible for promptly transferring the horse to a surgical facility and then dealing with aftercare and delayed complications. The surgeon is responsible for the intervening steps, including the decision on the need for surgery, and works with the anaesthesiologist to help a metabolically challenged patient to tolerate surgery and anaesthesia. Although early referral and improved diagnostic procedures can have a positive influence on survival, perceived improvements in surgery and anaesthesia need to be reviewed with some circumspection. Although more rigorous definitions and statistical analyses used in recent studies can invalidate comparisons with older studies, complication rates appear to be on the rise, despite putative improvements in dealing with them. This trend tends to diminish the value of colic surgery through increasing costs, overreliance on post-operative pharmacological management, growing pessimism, high rates of intraoperative euthanasia, and possibly reduced long-term survival. Future efforts should address these concerns, mostly through emphasis on prompt referral, good surgical technique and reducing the cost of colic surgery to an affordable level that saves more lives.

“…Administering appropriate intravenous fluid is a cornerstone of patient care during surgical perioperative periods and when managing various medical conditions. Despite years of medical research to determine the best dosing strategy for fluid therapy, published veterinary literature investigating intravenous fluid administration is mainly descriptive with little scientific evidence; thus, drawing solid, usable clinical values is difficult [31]. Fluid therapy protocols in small animal medicine are based predominantly on patient body weight and physical assessment [13], but clinical examination and vital signs, including arterial blood pressure, have little power to predict fluid responsiveness in humans [25] and are poorly correlated with intravascular volume status and cardiac output in dogs [35].…”

Fluid responsiveness, defined as the response of stroke volume to fluid loading, is a tool to individualize fluid administration in order to avoid the deleterious effects of hypovolemia or hypervolemia in hospitalized patients. To evaluate the accuracy of two ultrasound indices, the caudal vena cava to abdominal aorta ratio (CVC/Ao) and the respiratory collapsibility of the caudal vena cava (cCVC), as independent predictors of fluid responsiveness in a heterogeneous population of spontaneously breathing, conscious, hospitalized dogs. A prospective, multicenter, observational, cross-sectional study was designed in twenty-five dogs. The accuracy of CVC/ Ao and cCVC in predicting fluid responsiveness was evaluated by the area under the receiver operating characteristic curve (AUROC) in a group of hospitalized dogs after receiving a mini-fluid bolus of 4 ml/kg of Hartmann's solution. Dogs with an increased aortic velocity time integral >15% were classified as fluid responders. Twenty-two dogs were finally included. Ten were classified as responders and 12 as non-responders. The AUROC curves were 0.88 for the CVC/Ao ratio (95% confidence interval, CI, 0.67-0.98; P=0.0001) and 0.54 for cCVC (95% CI 0.32-0.75; P=0.75). The CVC/Ao threshold optimized for best sensitivity (SE) and specificity (SP) values was 0.83 (SE 100%; SP 75%). In spontaneously breathing hospitalized dogs, the CVC/Ao measurement predicted stroke volume increase after a fluid bolus, while the respiratory variations in the cCVC did not discriminate between fluid responders and non-responders.
