BACKYARD RABBIT PRODUCTION AS A SUSTAINABILITY SYSTEM IN THE URBAN AND PERI-URBAN AREA OF XOCHIMILCO REGION

ABSTRACT Mexico City has a long history of agriculture and, in spite of constant industrial growth, agricultural activities persist within its boundaries. Complex agricultural systems have their roots in the pre-Hispanic period, since then they have been modified and adapted with the introduction of metal tools, domestic animals and plants during the Spanish colony. The rabbit breeding activity at the urban y peri-urban area at southeast of Mexico City is an important part of the folder opportunities that local people have over their folder life opportunities. During the last decades the backyard rabbit production has been a neglected agricultural activity for the governmental plans, in spite of their meat production potential, sub-products utilisation and family integration. The rabbit occupation is characterised by low technological development, lack of technical advice and low breed and genetic quality. The results showed that the main concern of most of the rabbit breeders are: technical advice (including meat and processed sub products), broadcast and financial help to improve their production. The lack of a deep understanding of the whole system put its continuity at risk

PREVALENCE OF BOVINE LEPTOSPIROSIS AT TWO LOCALITIES IN PUNO DURING THE DRY SEASON AND DETERMINATION OF RISK FACTORS

La leptospirosis es una enfermedad zoonótica causada por una espiroqueta del género Leptospira, de distribución mundial que tiene gran impacto económico por las importantes pérdidas que ocasiona en la ganadería, sobre todo en la reproducción y la producción láctea, ya que tiene potencial abortivo y es causante de mortalidad neonatal, además de disminuir o anular la producción de leche. El objetivo del presente trabajo fue determinar la prevalencia de leptospirosis en bovinos en dos predios del departamento de Puno, Perú (Estación Experimental de ILLPA- INIA y Ganadería Cárdenas en la localidad de Mañazo), y su asociación con la época del año y las edad. Se recolectaron 116 muestras de sangre del total de animales de ambos predios, en la época seca. Los sueros se evaluaron mediante la Prueba de Aglutinación Microscópica (MAT) para la detección de anticuerpos, empleándose una batería de cuatro serovares (canicola, icterohaemorrhagiae, pomona y hardjo). Se obtuvo una prevalencia total de 2.6%, del cual 1.3% correspondió a animales de ILLPA-INIA y 5.3% a los animales de Mañazo. El serovar icterohaemorrhagiae fue el único prevalente con un nivel de anticuerpos de 1:200. Estos resultados sugieren una prevalencia baja de Leptospira sp en la época de seca en la zona estudiada.Leptospirosis is a disease caused by a spirochet of the genus Leptospira. It is aworld-wide zoonotic disease with a great economic impact because of the importantlosses that causes to livestock farmers, especially in terms of reproduction performanceand milk yield loses. The objective of the study was to estimate the prevalence ofleptospirosis in bovines in two farms in the department of Puno, Peru: the ILLPA-INIAExperimental Station and Cardenas farm at Mañazo and its association with season andage. One hundred and sixteen serum samples collected during the dry season wereevaluated. Blood samples were collected to all animals in both farms. The MicroscopicAgglutination Test (MAT) was used for the detection of antibodies through a set of fourserovars (canicola, icterohaemorrhagiae, pomona, and hardjo). The total prevalencewas 2.6% while 1.3% corresponded to animals at ILLPA-INIA and 5.3% to animals atMañazo. The icterohaemorrhagiae was the only prevalent serovar and the level ofantibodies was 1:200. The results suggested a low prevalence of Leptospira sp. in thedry season in the area of study

Toxoplasma gondii seropositivity associated to peri-urban living places in pregnant women in a rural area of Buenos Aires province, Argentina

Infection with Toxoplasma gondii is very common in humans throughout the world, the intake of raw or undercooked meat with tissue cysts and fruits, vegetables and water contaminated with parasite oocysts being the main routes of infection. Here, we analyzed the seroprevalence of anti-T. gondii antibodies in pregnant females (age 13–44 years; n = 920) between April 2014 and December 2017 from Chascomús (Argentina), a city immersed in a rural area. Altogether 320 tested positive for immunoglobulin G antibodies, yielding an overall seroprevalence of 34.8% (CI 95%: 31.7–37.9). No association was observed between seropositivity and age. In addition, by using the QGIS 3.2.1 software we analyzed the geographical distribution of 769 (83.6%) pregnant females in two main areas of the city: Urban (n = 157) and Peri-urban (n = 612) with a seroprevalence of 26.8% (CI 95%: 19.8–33.7) and 36.4% (CI 95%: 32.6–40.3) respectively, and this difference was statistically significant (p = 0.023). Furthermore, we assessed through a questionnaire survey, between April 2016 to December 2017, possible risk factors such as activity (urban and rural), home water supply, animal husbandry, presence of cats as pets, gardening and consumption of meat and its derivatives (pork, sheep meat and sausages) and their frequencies (consumption per week), not finding significant association with seropositivity. Significant differences was found when the seroprevalence was analyzed between the urban and peri-urban neighborhoods of the city of Chascomús. The higher seroprevalence in peri-urban neighborhoods could be due to an unfavorable socioeconomic situation and/or to undeveloped peri-urban environments, which is a risk factor that should be taken into account when planning the health care of pregnant females.Fil: Rivera, Elias Maximiliano.

Clinical Characteristics and Long-term outcomes of patients undergoing combined heart-kidney transplantation: a single-center experience

[Abstract] Background. The purpose of the study was to describe clinical characteristics and long-term survival of patients undergoing combined heart-kidney transplant in a single center. Methods. We conducted a retrospective analysis of 22 consecutive patients who underwent combined heart-kidney transplant at our institution between 1995 and 2013. Long-term outcomes were analyzed by means of the Kaplan-Meier method. Results. Four patients underwent re-do transplant (2 cardiac re-transplants, 1 kidney re-transplant, and 1 combined heart-kidney re-transplant). Most frequent underlying cardiac conditions were coronary artery disease (54%), dilated cardiomyopathy (23%), and chronic rejection of a previous heart graft (18%). Known causes of chronic renal dysfunction were nephroangioesclerosis (23%), drug-related toxicity (14%), and Wegener granulomatosis (5%). Non-specified chronic renal dysfunction was present in 50% patients. In-hospital postoperative mortality rate was 5 of 22 (23%). Causes of early death were directly related to kidney transplant surgery in 4 of 5 (80%) patients. Among the remaining 17 patients who surmounted the postoperative period, long-term survival rates 1 year, 5 years, and 10 years after HKT were 88%, 82%, and 65%, respectively. Over a mean follow-up of 6.7 ± 6.4 years, cumulative incidences of cytomegalovirus infection, coronary allograft vasculopathy, malignancy, and acute cardiac graft rejection were 41%, 6%, 24%, and 41%, respectively. There was no episode of acute renal graft rejection. At the end of follow-up, all survivors (n = 11) were in functional New York Heart Association class I. Mean creatinine serum level was 1.68 mg/dL. Conclusions. In our experience, combined heart-kidney transplant is a feasible therapeutic option that yielded favorable long-term outcomes, with a low cumulative incidence of cardiac graft dysfunction. These results were obtained at the expense of a significant risk of early postoperative mortality, which was mainly related to complications of kidney transplant surgery

Procesos urbanos en acción: ¿Desarrollo de ciudades para todos?

La presente colección Ciudades de la Gente representa a hombres y mujeres cuya cultura popular, producto de las mezclas de todos aquellos que vivían y otros que han llegado a nuestros territorios, han hecho de lugares declarados como no aptos, lugares donde vivir, y han creado dentro de nuestras ciudades, la extensión de lo distinto. Son hombres y mujeres cuyo trabajo, el que tienen para aportar, junto al de otros y otras de su misma condición, les ha permitido autoproducir interesantes y sin duda bellos espacios donde convivir. Los profesores e investigadores miembros del Grupo de Trabajo Hábitat Popular e Inclusión Social de CLACSO, nos unimos a todos aquellos hacedores que, superando los miedos y con deseos de avanzar, se atreven a caminar por lo desconocido y a no conformarse con lo conocido de otras realidades, buscando en conjunto afirmar, como derechos universales, las posibilidades de vidas dignas y de construcciones colectivas dentro de nuestras ciudades. Emprendemos la tarea de describir e interpretar el hábitat popular y la inclusión social, abriendo posibilidades para que, experimentados y debutantes líderes populares e investigadores, hablen sobre "las ciudades de la gente" de muy diversos modos

Prevention of ventilator-associated pneumonia: the multimodal approach of the spanish ICU pneumonia zero program.

Objectives: The “Pneumonia Zero” project is a nationwide multimodal intervention based on the simultaneous implementation of a comprehensive evidence-based bundle measures to prevent ventilator-associated pneumonia in critically ill patients admitted to the ICU. Design: Prospective, interventional, and multicenter study. Setting: A total of 181 ICUs throughout Spain. Patients: All patients admitted for more than 24 hours to the participating ICUs between April 1, 2011, and December 31, 2012. Intervention: Ten ventilator-associated pneumonia prevention measures were implemented (seven were mandatory and three highly recommended). The database of the National ICU-Acquired Infections Surveillance Study (Estudio Nacional de Vigilancia de Infecciones Nosocomiales [ENVIN]) was used for data collection. Ventilator-associated pneumonia rate was expressed as incidence density per 1,000 ventilator days. Ventilator-associated pneumonia rates from the incorporation of the ICUs to the project, every 3 months, were compared with data of the ENVIN registry (April–June 2010) as the baseline period. Ventilator-associated pneumonia rates were adjusted by characteristics of the hospital, including size, type (public or private), and teaching (postgraduate) or university-affiliated (undergraduate) status. Measurements and Main Results: The 181 participating ICUs accounted for 75% of all ICUs in Spain. In a total of 171,237 ICU admissions, an artificial airway was present on 505,802 days (50.0% of days of stay in the ICU). A total of 3,474 ventilator-associated pneumonia episodes were diagnosed in 3,186 patients. The adjusted ventilator-associated pneumonia incidence density rate decreased from 9.83 (95% CI, 8.42–11.48) per 1,000 ventilator days in the baseline period to 4.34 (95% CI, 3.22–5.84) after 19–21 months of participation. Conclusions: Implementation of the bundle measures included in the “Pneumonia Zero” project resulted in a significant reduction of more than 50% of the incidence of ventilator-associated pneumonia in Spanish ICUs. This reduction was sustained 21 months after implementation

Prevalence estimation of significant fibrosis because of NASH in Spain combining transient elastography and histology

Acord transformatiu CRUE-CSICBackground & Aims: Non-alcoholic fatty liver disease (NAFLD) has become a major public health problem, but the prevalence of fibrosis associated with non-alcoholic steatohepatitis (NASH) is largely unknown in the general population. This study aimed to provide an updated estimation of the prevalence of NASH fibrosis in Spain. Methods: This was an observational, retrospective, cross-sectional, population-based study with merged data from two Spanish datasets: a large (N = 12 246) population-based cohort (ETHON), including transient elastography (TE) data, and a contemporary multi-centric biopsy-proven NASH cohort with paired TE data from tertiary centres (N = 501). Prevalence for each NASH fibrosis stage was estimated by crossing TE data from ETHON dataset with histology data from the biopsy-proven cohort. Results: From the patients with valid TE in ETHON dataset (N = 11 440), 5.61% (95% confidence interval [95% CI]: 2.53-11.97) had a liver stiffness measurement (LSM) ≥ 8 kPa. The proportion attributable to NAFLD (using clinical variables and Controlled Attenuation Parameter) was 57.3% and thus, the estimated prevalence of population with LSM ≥ 8 kPa because of NAFLD was 3.21% (95% CI 1.13-8.75). In the biopsy-proven NASH cohort, 389 patients had LSM ≥ 8 kPa. Among these, 37% did not have significant fibrosis (F2-4). The estimated prevalence of NASH F2-3 and cirrhosis in Spain's adult population were 1.33% (95% CI 0.29-5.98) and 0.70% (95% CI 0.10-4.95) respectively. Conclusions: These estimations provide an accurate picture of the current prevalence of NASH-related fibrosis in Spain and can serve as reference point for dimensioning the therapeutic efforts that will be required as NASH therapies become available

First Oral Vaccination of Eurasian Wild Boar Against African Swine Fever Virus Genotype II

African swine fever (ASF), the most significant threat to the pig industry worldwide, has spread to more than 55 countries on three continents, and it affects more than 77% of the world swine population. In the European Union, wild boar (Sus scrofa) is the most severely affected host. The main reasons for the unprecedented and constant spread of ASF in Europe are the trade activities, the continuous movement of infected-wild boar populations among regions and the lack of vaccine to prevent ASF infection. In this study, we demonstrate that oral immunization of wild boar with a non-hemadsorbing, attenuated ASF virus of genotype II isolated in Latvia in 2017 (Lv17/WB/Rie1) conferred 92% protection against challenge with a virulent ASF virus isolate (Arm07). This is, to our knowledge, the first report of a promising vaccine against ASF virus in wild boar by oral administration. Further studies should assess the safety of repeated administration and overdose, characterize long-term shedding and verify the genetic stability of the vaccine virus to confirm if Lv17/WB/Rie1 could be used for free-ranging wild boar in ASF control programs
