Hematological disorders detected in dogs infected by Hepatozoon Canis in a municipality in Mato Grosso do Sul state, Brazil

A retrospective review of hematological reports of nine dogs detected with Hepatozoon canis infection by microscopic examination of blood smears in a laboratory in the municipality of Dourados, Mato Grosso do Sul, Brazil was conducted. This study aimed to evaluate the hematological profile of these infected dogs, in addition to the occurrence of coinfections with other agents that infect blood cells, since studies concerning canine hepatozoonosis in Brazil are scarce and there are some divergences regarding H. canis infection that still require a resolution. The nine cases of H. canis infection were identified among all dogs examined at the studied laboratory in 2009 and 2010, with an occurrence of 7/1,192 ( 0.59%; 95% CI 0.15 - 1.02%) positive dogs in the first year and 2/1,313 ( 0.15%; 95% CI 0.02 - 0.55%) cases in 2010. The analysis of the hematological reports showed an occurrence of coinfection between H. canis and other agents in two ( 2/9; 22.22%; 95% CI 2.81 - 60.00%) dogs, one with E. canis and another with Babesia spp. ( 1/9; 11.11%; 95% CI 0.28 - 48.24%). Only the blood test of one dog had no alterations, based on reference values. Anemia was the most frequent hematological alteration ( 6/9; 66.67%; 95% CI 29.93 - 92.51%). Although the occurrence of H. canis infection was low, significative hematological alterations were observed in most infected dogs. Coinfection with Babesia spp. and E. canis was detected in two dogs and the hematological alterations cannot be attributed exclusively to H. canis in these animals. Longitudinal studies would be of fundamental importance to determine the causality of these alterations. These results highlight the importance of differential diagnosis in dogs when there is clinical suspicion of infection by hemoparasites, since the hematological changes in dogs infected by H. canis are quite variable6851187119

A partir de este diagnóstico se han puesto en marcha actividades encaminadas a corregir las deficiencias de gestión encontradas

A Controversy That Has Been Tough to Swallow: Is the Treatment of Achalasia Now Digested?

Esophageal achalasia is a rare neurodegenerative disease of the esophagus and the lower esophageal sphincter that presents within a spectrum of disease severity related to progressive pathological changes, most commonly resulting in dysphagia. The pathophysiology of achalasia is still incompletely understood, but recent evidence suggests that degeneration of the postganglionic inhibitory nerves of the myenteric plexus could be due to an infectious or autoimmune mechanism, and nitric oxide is the neurotransmitter affected. Current treatment of achalasia is directed at palliation of symptoms. Therapies include pharmacological therapy, endoscopic injection of botulinum toxin, endoscopic dilation, and surgery. Until the late 1980s, endoscopic dilation was the first line of therapy. The advent of safe and effective minimally invasive surgical techniques in the early 1990s paved the way for the introduction of laparoscopic myotomy. This review will discuss the most up-to-date information regarding the pathophysiology, diagnosis, and treatment of achalasia, including a historical perspective. The laparoscopic Heller myotomy with partial fundoplication performed at an experienced center is currently the first line of therapy because it offers a low complication rate, the most durable symptom relief, and the lowest incidence of postoperative gastroesophageal reflux

Global overview of the management of acute cholecystitis during the COVID-19 pandemic (CHOLECOVID study)

Background: This study provides a global overview of the management of patients with acute cholecystitis during the initial phase of the COVID-19 pandemic. Methods: CHOLECOVID is an international, multicentre, observational comparative study of patients admitted to hospital with acute cholecystitis during the COVID-19 pandemic. Data on management were collected for a 2-month study interval coincident with the WHO declaration of the SARS-CoV-2 pandemic and compared with an equivalent pre-pandemic time interval. Mediation analysis examined the influence of SARS-COV-2 infection on 30-day mortality. Results: This study collected data on 9783 patients with acute cholecystitis admitted to 247 hospitals across the world. The pandemic was associated with reduced availability of surgical workforce and operating facilities globally, a significant shift to worse severity of disease, and increased use of conservative management. There was a reduction (both absolute and proportionate) in the number of patients undergoing cholecystectomy from 3095 patients (56.2 per cent) pre-pandemic to 1998 patients (46.2 per cent) during the pandemic but there was no difference in 30-day all-cause mortality after cholecystectomy comparing the pre-pandemic interval with the pandemic (13 patients (0.4 per cent) pre-pandemic to 13 patients (0.6 per cent) pandemic; P = 0.355). In mediation analysis, an admission with acute cholecystitis during the pandemic was associated with a non-significant increased risk of death (OR 1.29, 95 per cent c.i. 0.93 to 1.79, P = 0.121). Conclusion: CHOLECOVID provides a unique overview of the treatment of patients with cholecystitis across the globe during the first months of the SARS-CoV-2 pandemic. The study highlights the need for system resilience in retention of elective surgical activity. Cholecystectomy was associated with a low risk of mortality and deferral of treatment results in an increase in avoidable morbidity that represents the non-COVID cost of this pandemic

38 p.Paiz, A; Alemán, H. 2010. Análisis técnico – económico para mejorar la productividad de una explotación ganadera en la Ceiba, Honduras. Proyecto especial de graduación del programa de Ingeniero Agrónomo, Escuela Agrícola Panamericana, El Zamorano, Honduras. 38p. El monitoreo del desempeño de un hato es importante para definir planes o estrategias de acción que permitan obtener la máxima productividad. El peso, la condición corporal y la eficiencia reproductiva son aspectos que se deben tomar en cuenta al momento de evaluar un hato. Se realizó un estudio técnico-económico en la explotación lechera Rancho Adilia ubicado en el kilómetro 60 de la carretera Tela - La Ceiba durante Febrero y Julio del 2010. El análisis técnico incluyó: la evolución biológica del hato, una evaluación de todas las vacas para establecer los grupos de ordeño y la condición corporal; se observó la situación actual de la explotación para plantear mejoras en la infraestructura de las galeras de alimentación; finalmente se tomó en cuenta el uso y área de la tierra para realizar una mejora de las pasturas de corte y pastoreo y las instalaciones. El análisis financiero cuenta con dos escenarios para el crecimiento del hato siendo el primero un crecimiento basado en el crecimiento biológico y el segundo escenario considera la compra de ganado; se hará un préstamo al Banco Hondureño para la Producción y la Vivienda (BANHPROVI), con una tasa de interés del 10% a diez años con un año de gracia; a los dos escenarios se les sacó Valor Actual Neto (VAN) y Tasa Interna de Retorno (TIR). El Valor Actual Neto (VAN) del primer escenario es de $58,534.00 con una Tasa Interna de Retorno (TIR) del 73$ 61,104.00 con una TIR de 46%, en este escenario se hizo una calendarización de la compra entre octubre y noviembre porque en estos meses de invierno el precio del ganado es más bajo. Se eligió el segundo escenario con la de compra de ganado, debido que tiene un mayor VAN.1. Índice de cuadros, figuras y anexos 2. Introducción 3. Materiales y métodos 4. Metodología 5.

New members of Cygnus OB2 from Gaia DR2

Due to the high quality of Gaia DR2 stellar parallaxes and proper motions, we can study the Cygnus OB2 region up to G = 17.5 mag in circular region centred at (l, b) = (79.8°, +0.8°) of radius 1°. We detect four overdensities in the Vector Point Diagram. We apply a parametric model of the proper motion distribution and determine their mean proper motions, identify their members, and estimate their distances by analysing the parallaxes of the most probable members. We confirm that one of these regions is Cygnus OB2, whose mean proper motion is (μαcosδ, μδ) = (-2.71 ± 0.02, -4.24 ± 0.02) $mathrm{mas, yr}^{-1}$. We identify 2767 astrometric members at an estimated distance of 1683 ± 5 pc. A detailed comparison of these members with 333 photometric and spectroscopic Cygnus OB2 members shows that 33 stars of the last group are not members, 16 of them are O-B stars. 300 members in common lead to estimate a distance to the association of 1669 ± 6 pc. One of the remaining overdensities is the open cluster UCB585 for which we find eight more members, located at ∼1460 pc. The other two groups count 179 and 188 proper motion members which are distributed throughout the region and situated at a distance of ∼1280 pc. The estimated distances of these four groups suggest the existence of different substructures in the Cygnus OB2 region along the line of sight.Fil: Orellana, Rosa Beatriz.
