Changes in the gut microbiome and colic in horses: Are they causes or consequences?

The gut microbiome is a compound for millions of microorganisms that coexist in an organized way and contribute to the fermentation of different types of indigestible fibers by the small intestine. Some techniques, such as the massive sequencing of the 16S ribosomal RNA gene, have made it possible to obtain information about the abundance and functionality of the microorganisms that compose the equine gut microbiome and the interaction with their environment. Recent studies have identified the change in the composition of the intestinal microbiome during and after a colic episode, although is not clear if it is a cause or a consequence. The objective of this review was to elucidate whether there is a direct relationship between the changes that occur in the gut microbiome and colic in the equine. A systematized search in Embase, Web of Science, and PubMed was realized. Although there is good evidence that horses with colic have a change in their gut microbiome, it is not fully understood whether these changes are causes or effects. It is necessary to delve into this topic, considering studying larger population sizes. In addition, it would be of great value to previously know the normal intestinal microbiome of a group of healthy horses, which in the future could develop an episode of colic, to compare the before and after in the same individual.

Ocular Microbiome in a Group of Clinically Healthy Horses.

The ocular microbiome in horses is poorly described compared to other species, and most of the information available in the literature is based on traditional techniques, which has limited the depth of the knowledge on the subject. The objective of this study was to characterize and predict the metabolic pathways of the ocular microbiome of a group of healthy horses. Conjunctival swabs were obtained from both eyes of 14 horses, and DNA extraction was performed from the swabs, followed by next generation sequencing and bioinformatics analyses employing DADA2 and PICRUSt2. A total of 17 phyla were identified, of which Pseudomonadota (Proteobacteria) was the most abundant (59.88%), followed by Actinomycetota (Actinobacteria) (22.44%) and Bacteroidota (Bacteroidetes) (16.39%), totaling an average of 98.72% of the communities. Similarly, of the 278 genera identified, Massilia, Pedobacter, Pseudomonas, Sphingomonas, Suttonella and Verticia were present in more than 5% of the samples analyzed. Both Actinobacteria and Bacteroides showed great heterogeneity within the samples. The most abundant inferred metabolic functions were related to vital functions for bacteria such as aerobic respiration, amino acid, and lipid biosynthesis.

First Case Report of Aspergillary Rhinopharyngitis in a Foal From Chile.

We present the first case of rhinopharyngitis due to Aspergillus fumigatus in a purebred Chilean horse. Clinically, manifested mucopurulent discharge from both nostrils, inflammation of the nasal, ocular, and ear mucosa; associated with decay and hyporexia. Based on the clinical signs and analysis of the mycological and molecular transtracheal aspirate sample, the present case was diagnosed as Aspergillus fumigatus rhinopharyngitis. After the antifungal susceptibility test, oral itraconazole treatment was maintained for 45 days, showing no clinical sign.

Recommendations for local-regional anesthesia during the COVID-19 pandemic.

Since the beginning of the COVID-19 pandemic, many questions have come up regarding safe anesthesia management of patients with the disease. Regional anesthesia, whether peripheral nerve or neuraxial, is a safe alternative for managing patients with COVID-19, by choosing modalities that mitigate pulmonary function involvement. Adopting regional anesthesia mitigates adverse effects in the post-operative period and provides safety to patients and teams, as long as there is compliance with individual protection and interpersonal transmission care measures. Respecting contra-indications and judicial use of safety techniques and norms are essential. The present manuscript aims to review the evidence available on regional anesthesia for patients with COVID-19 and offer practical recommendations for safe and efficient performance.

Desde o início da pandemia de COVID-19, muitas questões surgiram referentes à segurança do manejo anestésico de pacientes acometidos pela doença. A anestesia regional, seja esta periférica ou neuroaxial, é alternativa segura no manejo do paciente COVID-19, desde que o emprego de modalidades que minimizam o comprometimento da função pulmonar seja escolhido. A adoção desta técnica anestésica minimiza os efeitos adversos no pós-operatório e oferece segurança para o paciente e equipe, desde que sejam respeitados os cuidados com proteção individual e de contágio interpessoal. Respeito às contraindicações e emprego criterioso das técnicas e normas de segurança são fundamentais. Este manuscrito tem por objetivo revisar as evidências disponíveis sobre anestesia regional em pacientes com COVID-19 e oferecer recomendações práticas para sua realização segura e eficiente.

Anestesia em paciente com insensibilidade congênita a dor e anidrose / Anestesia en paciente con insensibilidad congénita al dolor y anhidrosis / Anesthesia in a patient with congenital insensitivity to pain and anhidrosis

JUSTIFICATIVA E OBJETIVOS: A insensibilidade congênita a dor e anidrose (ICDA) ou neuropatia hereditária sensorial e autonômica tipo IV (NHSA tipo IV) é neuropatia autossômica recessiva rara do grupo das neuropatias hereditárias sensoriais e autonômicas (NHSA), caracterizada por insensibilidade ao estímulo doloroso, anidrose e retardo mental. Existem poucos relatos sobre a conduta anestésica em pacientes com ICDA devido sua extrema raridade. O objetivo deste relato foi apresentar a conduta anestésica em paciente com ICDA submetida à artrodese de tornozelo esquerdo com colocação de haste e discutir as características de interesse para a anestesia nestes pacientes. RELATO DO CASO: Paciente com história de ICDA foi admitida para artrodese de tornozelo esquerdo devido à artropatia de Charcot. Na sala de operação foi monitorizada com eletrocardiógrafo, índice bispectral, SEF 95 por cento, pressão arterial não invasiva e saturação periférica da hemoglobina, medicada com midazolam como pré-anestésico e submetida à anestesia venosa com propofol e cisatracúrio. Não houve a necessidade de administração de analgésicos. Após intubação traqueal, foi acrescentada monitorização da pressão expiratória final do gás carbônico e da temperatura esofágica. Não apresentou complicações no período perioperatório. Teve alta hospitalar no segundo dia de pós-operatório. CONCLUSÕES: Embora apresentem insensibilidade à dor, alguns pacientes apresentam hiperestesia tátil, o que poderia causar sensações desagradáveis durante a manipulação cirúrgica. Apesar de relatos na literatura de pacientes submetidos a bloqueios no neuroeixo e até mesmo a procedimentos sem anestesia, neste caso utilizou-se a anestesia venosa que proporcionou condições adequadas para o procedimento anestésico-cirúrgico.

ACKGROUND AND OBJECTIVES: Congenital insensitivity to pain and Anhidrosis (CIPA) or hereditary sensory and autonomic neuropathy type IV (HSAN IV) is a rare autosomal recessive neuropathy of the group of hereditary sensory and autonomic neuropathies (HSAN) characterized by insensitivity to pain, anhidrosis, and mental retardation. Since it is a rare condition, reports on the anesthetic conduct in patients with CIPA are not easily found in the literature. The objective of this report was to present the anesthetic conduct in a patient with CIPA undergoing left ankle arthrodesis with placement of an implant, and to discuss the characteristics of this disorder that concern anesthesiologists the most. CASE REPORT: A female patient with a history of CIPA was admitted for left ankle arthrodesis due to Charcot arthropathy. In the operating room, the patient was monitored with an electrocardiograph, bispectral index, 95 percent SEF, non-invasive blood pressure, and peripheral hemoglobin saturation; she was pre-medicated with midazolam and underwent intravenous anesthesia with propofol and cisatracurium. The administration of analgesics was not necessary. After tracheal intubation, monitoring of end-expiratory pressure of carbon dioxide and esophageal temperature were added. The patient did not develop postoperative complications. She was discharged from the hospital on the second postoperative day. CONCLUSIONS: Although there is insensitivity to pain, some patients present tactile hyperesthesia that can cause unpleasant feelings during surgical manipulation. Despite reports in the literature of patients undergoing neuroaxis blocks, and even procedures without anesthesia, intravenous anesthesia, which provided adequate conditions for the anesthetic-surgical procedure was used in this case.
