Effect of Butorphanol-Medetomidine and Butorphanol-Dexmedetomidine on Echocardiographic Parameters during Propofol Anaesthesia in Dogs.

This study compared the effects of butorphanol-medetomidine and butorphanol-dexmedetomidine combinations on echocardiographic parameters during propofol anaesthesia in dogs. The dogs were randomly divided into two groups. In the butorphanol-medetomidine (BM) group, butorphanol (0.2 mg/kg) and medetomidine (15 µg/kg) were intravenously administered; in the butorphanol-dexmedetomidine (BD) group, butorphanol (0.2 mg/kg) and dexmedetomidine (7.5 µg/kg) was used. Anaesthesia was induced with propofol and maintained with a constant-rate infusion of propofol (0.2 mg/kg/min). The echocardiographic parameters were assessed in conscious dogs (T0). Echocardiography was conducted again at 10 min post premedication (T1), followed by assessments at 30 (T2), 60 (T3), and 90 (T4) mins. The dogs were subjected to diagnostic procedures (radiography, computed tomography) under anaesthesia. A significant reduction in heart rate and cardiac output was noted in both groups at T1. There was no significant difference in the stroke volume between the BM and BD groups. The application of butorphanol-dexmedetomidine caused a significant increase in the left ventricular internal diameter in diastole and the diameter of the left atrium compared to that caused by butorphanol-medetomidine. This study documented that butorphanol-medetomidine and butorphanol-dexmedetomidine combinations caused similar reductions in heart rate and cardiac output in both groups. 'New´ valvular regurgitation occurred following their administration.

A Practical Overview of the Articular Manifestations of Systemic Lupus Erythematosus.

Although it is widely known that joint involvement is the most frequent and prevalent manifestation of systemic lupus erythematosus (SLE), not having a validated organ-specific index for this domain in order to guide its treatment has been a major limitation. In addition, its clinical importance had been underestimated since it was not a vital risk domain; it was never the center of treatment, under the premise that in most cases its progression was slow and did not lead to significant functional disability. However, this concept has been changing due to the greater description of erosions both in ultrasonography and in osteoarticular magnetic resonance, so their identification can establish a more appropriate treatment time and thus avoid joint deformities, which in some cases can become irreversible. Recently, anifrolumab and belimumab have been able to significantly reduce the Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K) and British Isles Lupus Assessment Group (BILAG) index scores, along with improvement in quality of life indices and a significant decrease in the required dose of glucocorticoids. Despite this, the ideal moment to consider biological therapy in this domain is not clear, since the clinical examination can sometimes be biased by the pain associated with fibromyalgia or the fatigue associated with SLE. For this reason, perhaps ultrasonography or magnetic resonance imaging, apart from differentiating the joint phenotype, can identify patients in time to define the onset of disease-modifying antirheumatic drugs and rationalize the use of glucocorticoids. The objective of this review is to characterize in detail the joint manifestations of SLE to offer the clinician a practical view of its diagnosis and treatment.

Bone involvement in non-congenital syphilis / Compromiso óseo por sífilis no congénita

We documented two stages of bone involvement due to syphilis in two adult patients infected with human immunodeficiency virus. Bony lesions of secondary versus tertiary syphilis cannot be differentiated on clinical or radiologic grounds alone. Given the rarity of this clinical presentation, there is no consensus on treatment duration and related outcomes.

Se describen dos etapas de compromiso óseo por sífilis en dos pacientes adultos infectados por el virus de la inmunodeficiencia humana. Las lesiones óseas de la sífilis secundaria y de la sífilis terciaria no se pueden diferenciar únicamente por características clínicas o radiológicas. Dada la rareza de esta presentación clínica, no hay consenso sobre la duración del tratamiento y los resultados relacionados.

HIV/AIDS infection in critical care: epidemiological profile and risk factors for mortality in a Colombian cohort.

INTRODUCTION: Outcomes of human immunodeficiency virus (HIV) infected patients admitted to intensive care units (ICU) have improved with antiretroviral therapy (ART). However, whether the outcomes have improved in low- and middle-income countries, paralleling those of high-income countries is unknown. The objective of this study was to describe a cohort of HIV-infected patients admitted to ICU in a middle-income country and identify the risk factors associated with mortality. METHODOLOGY: A cohort study of HIV-infected patients admitted to five ICUs in Medellín, Colombia, between 2009 and 2014 was done. The association of demographic, clinical and laboratory variables with mortality was analyzed using a Poisson regression model with random effects. RESULTS: During this time period, 472 admissions of 453 HIV-infected patients were included. Indications for ICU admission were: respiratory failure (57%), sepsis/septic shock (30%) and central nervous system (CNS) compromise (27%). Opportunistic infections (OI) explained 80% of ICU admissions. Mortality rate was 49%. Factors associated with mortality included hematological malignancies, CNS compromise, respiratory failure, and APACHE II score ≥ 20. CONCLUSIONS: Despite advances in HIV care in the ART era, half of HIV-infected patients admitted to the ICU died. This elevated mortality was associated to underlying disease severity (respiratory failure and APACHE II score ≥ 20), and host conditions (hematological malignancies, admission for CNS compromise). Despite the high prevalence of OIs in this cohort, mortality was not directly associated to OIs.

Cardiology in Rodents, Rabbits, and Small Exotic Mammals-Diagnostic Workup.

The incidence of cardiac diseases in pet rabbits and rodents increased over the past decade as these species live longer and diagnostics methods are more precise to diagnose heart diseases even in small-sized animals. The article summarizes diagnostics of cardiac diseases in selected exotic companion mammals, particularly in rabbits, guinea pigs, chinchillas, and rats. The emphasis of the paper is given on clinical examination, thoracic radiography, electrocardiography, and echocardiography.

Serum Proteomic Changes in Dogs with Different Stages of Chronic Heart Failure.

MMVD, the most common cause of CHF in dogs, is a chronic disease with variable clinical signs, with some patients remaining asymptomatic while others develop CHF. Here, we aimed to evaluate serum proteins by proteomic analysis in dogs at different stages of CHF due to MMVD, and proteome behaviors after conventional treatment. A total of 32 dogs were divided equally into four groups-stage A (healthy/controls), stage B2 (asymptomatic), stage C and stage D (symptomatic)-according to the ACVIM consensus. Serum proteomes were evaluated using LC/MS-based label-free differential proteome analysis. The study revealed 157 different proteins; 11 were up- and 21 down-regulated in dogs with CHF compared to controls. In stage B2 dogs, angiotensinogen (AGT) was up-regulated, but immunoglobulin iota chain-like, lipopolysaccharide-binding protein, and carboxypeptidase (CPN) were down-regulated. In stage C dogs, complement C3 (C3) and inter-alpha-trypsin inhibitor heavy chain were up-regulated, but hemopexin, and actin-cytoplasmic-1 (ACT-1) were down-regulated. In stage D dogs, AGT was up-regulated, whereas tetranectin, paraoxonase-1, adiponectin and ACT-1 were down-regulated. A decrease in CPN, C3 and AGT and an increase in ACT-1 were observed after treatment of dogs in stage C. This pilot study identified that dogs at different stages of CHF show different serum protein composition which has potential to be biomarker for diagnose and treatment monitorization.

Acute Q Fever With Dermatologic Manifestations, Molecular Diagnosis, and No Seroconversion.

The infection was confirmed by molecular detection through real-time polymerase chain reaction using genomic DNA collected from peripheral blood.

Genetic Diversity of Multidrug-Resistant Pseudomonas aeruginosa Isolates Carrying bla VIM-2 and bla KPC-2 Genes That Spread on Different Genetic Environment in Colombia.

Pseudomonas aeruginosa is an opportunistic Gram-negative pathogen with an increase in the frequency of infections caused by multidrug resistant (MDR) and extensively drug resistant (XDR) strains, limiting the available therapeutic options. The most troublesome resistance is the acquisition and production of carbapenemases such as Verona integron-encoded metallo-ß-lactamases (VIM), the most frequent and widespread, and the Klebsiella pneumoniae carbapenemases (KPC), which has continuously spread in the last decade. Its dissemination is linked to their location on mobile genetic elements (MGEs). In Colombia, VIM and KPC have been increasing in its frequency showing major successful dissemination. In this article, we molecularly characterized and analyzed the genetic context of bla VIM and bla KPC in carbapenem-resistant P. aeruginosa (CRPA) isolates from infected and colonized patients in two tertiary-care hospitals, one in Medellín and the other in a municipality close to Medellín, both areas with high carbapenemase endemicity in Colombia (2013-2015). Using whole-genome sequencing (WGS), we identified a remarkable variety of genetic backgrounds in these MDR P. aeruginosa isolates carrying bla KPC- 2 and bla VIM- 2. There were a diversity of class 1 integron and variations in the gene cassettes associated to bla VIM- 2, as well as a possible event of spread of bla KPC- 2 mediated by a plasmid that contained part of Tn4401b in one infection case. The dissemination of bla VIM- 2 and bla KPC- 2 in P. aeruginosa in this area in Colombia has been strongly influenced by successful international clones, carrying these genes and additional determinants of resistance on MGEs, accompanied by gene rearrangement under an antimicrobial selection pressure. These findings emphasize the need to implement control strategies based on rational antibiotic use.

Rhinosporidiosis in the Americas: A Systematic Review of Native Cases.

Rhinosporidiosis is a chronic mucosal infection caused by Rhinosporidium seeberi, an aquatic protistan parasite. It presents as nasal or ocular polypoidal or vascularized masses. It is endemic in tropical and subtropical areas, especially in South Asia; R. seeberi´s endemicity in the Americas is often overlooked. The objective of this study was to describe the demographic and clinical characteristics of patients with rhinosporidiosis in the Americas, its management, and patient outcomes. This study is a systematic review of cases of human rhinosporidiosis in the Americas reported in the literature from 1896 to February 28, 2019. This review screened 1,994 reports, of which 115 were eligible for further analysis. The selected reports described 286 cases of human rhinosporidiosis between 1896 and 2019. Cases were diagnosed in Brazil (32.2%), Colombia (24.4%), Paraguay (12.6%), and the United States (11.9%). The majority of the cases (91%) occurred in geographic areas with altitudes < 1,000 m above sea level and in areas with median temperatures ≥ 25°C (67.3%). Most of the patients presented nasal (65%) and ocular involvement (35%). Surgical treatment was provided for 99.6% of patients, but 19.8% of them recurred. This review describes the under-recognized geographic distribution and clinical presentation of rhinosporidiosis in the Americas and highlights clinical differences to cases in Asia, specifically in reference to a higher prevalence of ocular disease and higher relapse rates.

A case of a complete atrioventricular canal defect in a ferret.

BACKGROUND: Atrioventricular canal defect is a rare congenital disorder of the heart and describes the presence of an atrial septal defect, a variable presentation of ventricular septal alterations including ventricular septal defect malformations in the mitral and tricuspid valves. The defect has been described in human beings, dogs, cats, pigs, and horses. CASE PRESENTATION: This paper describes the case of a complete atrioventricular canal defect in a four-year-old intact male pet ferret (Mustela putorius furo), which was presented due to posterior weakness, ataxia, and decreased appetite. A loud systolic murmur, dyspnea, and hind limb paraparesis were detected during the clinical examination. Thoracic radiographs showed generalized cardiomegaly and lung edema. ECG showed sinus rhythm with prolonged P waves and QRS complexes. Echocardiography showed a large atrial septal defect, atrioventricular dysplasia, and a ventricular septal defect. Palliative treatment with oxygen, furosemide, spironolactone, enalapril, diltiazem, and supportive care was chosen as the therapy of choice. The ferret recovered gradually during hospitalization. A follow-up examination at three and six months showed stabilization of cardiac function. CONCLUSIONS: To the authors knowledge, this is the first time an atrioventricular canal defect has been described in a pet ferret.

Outcomes and complications of hospitalised patients with HIV-TB co-infection.

BACKGROUND: Tuberculosis is one of the most common causes of hospitalisation in patients with HIV. Despite this, hospital outcomes of patients with this co-infection have rarely been described since antiretroviral therapy became widely available. METHODS: Prospective cohort study of HIV-infected adult patients hospitalised with TB in six referral hospitals in Medellin, Colombia, from August 2014 to July 2015. RESULTS: Among 128 HIV-infected patients hospitalised with tuberculosis, the mean age was 38.4 years; 79.7% were men. HIV was diagnosed on admission in 28.9% of patients. The median CD4 + T-cell count was 125 (±158 SD) cells/µL. Only 47.3% of patients with a known diagnosis of HIV upon admission were on antiretroviral therapy, and only 11.1% had a tuberculin skin test in the previous year. Drug toxicity due to tuberculosis medications occurred in 11.7% of patients. Mean length of stay was 23.2 days, and 10.7% of patients were readmitted. Mortality was 5.5%. CONCLUSIONS: Hospital mortality attributable to tuberculosis in patients with HIV is low in reference hospitals in Colombia. Cases of tuberculosis in HIV-infected patients occur mainly in patients with advanced HIV, or not on antiretroviral therapy, despite a known diagnosis of HIV. Only one of every 10 patients in this cohort had active screening for latent tuberculosis, possibly reflecting missed treatment opportunities.

CONTEXTE: La tuberculose (TB) est l'une des causes les plus courantes d'hospitalisation chez les patients VIH positifs. Malgré cela, les résultats hospitaliers des patients atteints de cette coinfection ont rarement été décrits depuis que le traitement antirétroviral est devenu largement disponible. MÉTHODES: Etude de cohorte prospective de patients adultes infectés par le VIH hospitalisés pour TB dans six hôpitaux de référence à Medellin, en Colombie, d'août 2014 à juillet 2015. RÉSULTATS: Sur 128 patients infectés par le VIH hospitalisés pour TB, l'âge moyen était de 38,4 ans; 79,7% étaient des hommes. Le VIH a été diagnostiqué à l'admission chez 28,9% des patients. Le nombre médian de lymphocytes T CD4+ était de 125 (±158 SD) cellules/µL. Seuls 47,3% des patients dont le diagnostic de VIH était connu lors de leur admission étaient sous traitement antirétroviral et 11,1% seulement avaient subi un test cutané à la tuberculine l'année précédente. Une toxicité médicamenteuse due aux médicaments antituberculeux est survenue chez 11,7% des patients. La durée moyenne de séjour était de 23,2 jours et 10,7% des patients ont été réadmis. La mortalité était de 5,5%. CONCLUSIONS: La mortalité hospitalière attribuable à la TB chez les patients VIH positifs est faible dans les hôpitaux de référence en Colombie. Les cas de TB chez les patients infectés par le VIH surviennent principalement chez les patients à un stade avancé du VIH, ou qui ne sont pas sous traitement antirétroviral, malgré un diagnostic connu de VIH. Seul un patient sur 10 de cette cohorte a subi un dépistage actif de la TB latente, ce qui reflète peut-être des opportunités de traitement manquées.

Fermented Non-Digestible Fraction of Andean Berry (Vaccinium meridionale Swartz) Juice Induces Apoptosis in Colon Adenocarcinoma Cells.

Vaccinium meridionale Swartz, known as Andean berry, has a high content of anthocyanins, phenolic acids, and other flavonoids due to their putative anticancer activity. However, after consumption, the structures and function of these molecules may be altered. The purpose of this study was to evaluate the pro-apoptotic effect of fermented non-digestible fraction (FNDF) of Andean berry juice (ABJ) on colon adenocarcinoma HT29 cells. HT29 cells were treated by FNDF-ABJ obtained by in vitro gastrointestinal fermentation. We determined the proapoptotic capacity by terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assays, oxidative stress by analyzing superoxide dismutase and catalase activity, lipid peroxidation by measuring 8-iso-prostaglandin F2α, and measured lactate dehydrogenase. Our results show that FNDF-ABJ inhibited cell growth [lethal dose 50(%)=26% v/v]. In addition, FNDF-ABJ increased the number of TUNEL positive cells 2-fold compared with untreated cells without altering the release of lactate dehydrogenase. However, superoxide dismutase activity was reduced in HT29 cells treated with FNDF-ABJ, catalase activity was not affected and 8-iso-prostaglandin F2α levels were increased. These results support that the anti-proliferative effects of FNDF-ABJ on HT29 cells can be explained by apoptotic mechanisms.

Dynamics of blaKPC-2 Dissemination from Non-CG258 Klebsiella pneumoniae to Other Enterobacterales via IncN Plasmids in an Area of High Endemicity.

Carbapenem-resistant Enterobacterales (CRE) pose a significant threat to global public health. The most important mechanism for carbapenem resistance is the production of carbapenemases. Klebsiella pneumoniae carbapenemase (KPC) represents one of the main carbapenemases worldwide. Complex mechanisms of blaKPC dissemination have been reported in Colombia, a country with a high endemicity of carbapenem resistance. Here, we characterized the dynamics of dissemination of blaKPC gene among CRE infecting and colonizing patients in three hospitals localized in a highly endemic area of Colombia (2013 and 2015). We identified the genomic characteristics of KPC-producing Enterobacterales recovered from patients infected/colonized and reconstructed the dynamics of dissemination of blaKPC-2 using both short and long read sequencing. We found that spread of blaKPC-2 among Enterobacterales in the participating hospitals was due to intra- and interspecies horizontal gene transfer (HGT) mediated by promiscuous plasmids associated with transposable elements that was originated from a multispecies outbreak of KPC-producing Enterobacterales in a neonatal intensive care unit. The plasmids were detected in isolates recovered in other units within the same hospital and nearby hospitals. The gene "epidemic" was driven by IncN-pST15-type plasmids carrying a novel Tn4401b structure and non-Tn4401 elements (NTEKPC) in Klebsiella spp., Escherichia coli, Enterobacter spp., and Citrobacter spp. Of note, mcr-9 was found to coexist with blaKPC-2 in species of the Enterobacter cloacae complex. Our findings suggest that the main mechanism for dissemination of blaKPC-2 is HGT mediated by highly transferable plasmids among species of Enterobacterales in infected/colonized patients, presenting a major challenge for public health interventions in developing countries such as Colombia.

La violencia intrafamiliar en el desempeño laboral de las mujeres en el sector textil-confección / Domestic violence in the labor performance of women in the textile-confection industry

Resumen El objetivo principal de la investigación fue conocer los factores que se derivan de la violencia intrafamiliar y la incidencia en la productividad laboral en empresas del sector textil confección. Inicialmente, se realizó una revisión de la literatura, para luego desarrollar el proyecto investigativo bajo el paradigma interpretativo, haciendo énfasis, en identificar cómo el fenómeno de la violencia intrafamiliar impacta el desempeño laboral de las trabajadoras de este tipo de empresas. La metodología fue cualitativa, con un diseño transversal, y se utilizó la técnica de recolección de información por medio de un grupo focal y una entrevista semiestructurada con preguntas orientadoras. En los resultados se pudo constatar que la violencia intrafamiliar es un factor que incide en el bajo nivel de desempeño y productividad de las trabajadoras; donde el desempeño laboral se ve afectado por esta situación impactando la baja calidad en el trabajo. Así mismo, se estableció que las organizaciones no cuentan con una ruta de atención que ofrezca apoyo a las mujeres víctimas de la violencia intrafamiliar.

Abstract The main objective of the research was to know the factors that are derived from intrafamily violence and the incidence of labor productivity in companies in the textile clothing industry. Initially, a review of the literature was made, to then develop the research project under the interpretive paradigm, emphasizing, in identifying how the phenomenon of intrafamily violence impacts the work performance of workers of this type of companies. The methodology was a qualitative approach, a cross-sectional design, and the technique of gathering information was used through a focus group and a semi-structured interview with guiding questions. In the results obtained, it was found that intrafamily violence is a factor that affects the low level of performance and productivity in workers; where the work performance is affected by this situation having impact on the low quality at work. Likewise, it was established that organizations do not have a care route that offers support to women victims of domestic violence.

Acute Respiratory Failure after Administration of Hydrogen Peroxide as an Emetic in a Cat.

OBJECTIVE AND CASE SUMMARY: This case report describes a 5-year-old domestic short-haired cat that was orally administered with 4 mL of 3% hydrogen peroxide by the owner after suspecting ingestion of a foreign body by the cat. Shortly after the administration, the cat developed severe respiratory distress. Thoracic radiography showed an interstitial-to-alveolar pulmonary pattern, while echocardiography and heart injury markers ruled out a cardiac origin. Intensive management with oxygen, diuretics, bronchodilators, and sedation resulted in survival of the cat without further respiratory complications. NEW AND UNIQUE INFORMATION PROVIDED: To the best of our knowledge, this is the first report of a lung injury and acute respiratory failure after administration of hydrogen peroxide in a cat with successful management.

Abstract Introduction: History of recent or active upper respiratory tract infection is common in many children undergoing general anesthesia procedures. Objective: To conduct a narrative review of anesthetic management guidelines for children with recent or active upper respiratory tract infection. Materials and methods: A structured literature search was conducted in ProQuest, EBSCO, ScienceDirect, PubMed, LILACS, Embase, Trip Database, SciELO and Cochrane Library databases with the terms Anesthesia AND Respiratory Tract Infections AND Complications; Anesthesia AND Upper respiratory tract infection AND Complications; Anesthesia, General AND Respiratory Tract Infections AND Complications; Anesthesia, General AND Upper respiratory tract infection AND Complications; Anesthesia AND Laryngospasm OR Bronchospasm. The search was done in English with its equivalents in Spanish. Results: 56 articles had information relevant to meet the objective of this review. Conclusions: Minimizing manipulation of the airway tends to decrease the frequency and severity of perioperative adverse respiratory events. There is not sufficient evidence to recommend drug optimization in patients with upper respiratory tract infection.

Rhinosporidiosis in Colombia: case series and literature review.

Rhinosporidiosis is a chronic granulomatous disease that affects mucosal surfaces. Its epidemiology and clinical presentation in Colombia are not well-known. We therefore reviewed all 58 reported cases between 1964 and 2015 to raise awareness among clinicians in a non-endemic area. Of the patients, 64% were male (median age = 15 years) and 57% had ocular and 43% nasal manifestations; there were no disseminated cases of the disease. All lesions were surgically removed.

Bioaccessibility during In Vitro Digestion and Antiproliferative Effect of Bioactive Compounds from Andean Berry ( Vaccinium meridionale Swartz) Juice.

Berry consumption is associated with colorectal-cancer chemoprevention, but digestive conditions can affect this property. The bioaccessibility and apparent permeability coefficients of bioactive compounds from Andean Berry Juice (ABJ) after in vitro gastrointestinal digestion and colonic fermentation were analyzed. The antiproliferative effect of the fermented nondigestible fraction was evaluated against SW480 colon-adenocarcinoma cells. Gallic acid displayed the highest bioaccessibility in the mouth, stomach, small intestine, and colon. However, chlorogenic acid exhibited the highest apparent permeability coefficients (up to 1.98 × 10-4 cm/s). The colonic-fermentation fraction showed an increase of ≥50% antiproliferative activity against SW480 cells (19.32%, v/v), equivalent to those of gallic acid (13.04 µg/g), chlorogenic acid (7.07 µg/g), caffeic acid (0.40 µg/g), ellagic acid (7.32 µg/g), rutin (6.50 µg/g), raffinose (0.14 mg/g), stachyose (0.70 mg/g), and xylose (9.41 mg/g). Bioactive compounds from ABJ are bioaccessible through the gastrointestinal tract and colon fermentation, resulting in antiproliferative activity.
