Ovaries were checked by transrectal ultrasonography at the time of DUI and sows were classified into three categories: F-: ovarian pre-ovulatory follicles were visible during two examinations; O-: ovulation visible during one examination; and C-sows: corpora hemorragica visible during the two examinations. Overall farrowing rates differed (

La leche de vaca es un alimento básico en la alimentación humana en todas las etapas de la vida. Su procesamiento industrial ha permitido el acceso generalizado a su consumo por parte de la ...población, lo que ha contribuido a mejorar notablemente su nivel de salud. Desde el punto de vista de su composición, la leche es un alimento completo y equilibrado, que proporciona un elevado contenido de nutrientes en relación con su contenido calórico, por lo que su consumo debe considerarse necesario desde la infancia a la tercera edad. Los beneficios de la leche de vaca no se limitan exclusivamente a su valor nutricional, sino que se extienden más allá y constituyen un factor de prevención en determinadas patologías afluentes como son la enfermedad cardiovascular, algunos tipos de cáncer, la hipertensión arterial o en patología ósea o dental. Puede contribuir también en la lucha frente al sobrepeso y la obesidad infantil. En los últimos años hemos asistido a un descenso preocupante en el consumo de leche entre la población española, condicionado al menos en parte por ideas equivocadas sobre su consumo y el de otros derivados lácteos. Este documento de consenso pretende revisar el estado actual de la cuestión en relación con los efectos del consumo de leche sobre la salud, al tiempo que hace una llamada a las instituciones y a las sociedades científicas para elaborar programas y campañas divulgativas sobre los beneficios del consumo de leche y derivados lácteos.
The study aimed to describe the epidemiological, microbiological, and clinical features of a population sample of 17 patients with HACEK infective endocarditis (HACEK-IE) and to compare them with ...matched control patients with IE caused by viridans group streptococci (VGS-IE).
Cases of definite (n=14, 82.2%) and possible (n=3, 17.6%) HACEK-IE included in the Infective Endocarditis Hospital Clinic of Barcelona (IE-HCB) database between 1979 and 2016 were identified and described. Furthermore, a retrospective case–control analysis was performed, matching each case to three control subjects with VGS-IE registered in the same database during the same time period.
Seventeen out of 1209 IE cases (1.3%, 95% confidence interval 0.69–1.91%) were due to HACEK group organisms. The most frequently isolated HACEK species were Aggregatibacter spp (n=11, 64.7%). Intracardiac vegetations were present in 70.6% of cases. Left heart failure (LHF) was present in 29.4% of cases. Ten patients (58.8%) required in-hospital surgery and none died during hospitalization. In the case–control analysis, there was a trend towards larger vegetations in the HACEK-IE group (median (interquartile range) size 11.5 (10.0–20.0) mm vs. 9.0 (7.0–13.0) mm; p=0.068). Clinical manifestations, echocardiographic findings, LHF rate, systemic emboli, and other complications were all comparable (p>0.05). In-hospital surgery and mortality were similar in the two groups. One-year mortality was lower for HACEK-IE (1/17 vs. to 6/48; p=0.006).
HACEK-IE represented 1.3% of all IE cases. Clinical features and outcomes were comparable to those of the VGS-IE control group. Despite the trend towards a larger vegetation size, the embolic event rate was not higher and the 1-year mortality was significantly lower for HACEK-IE.
The Influenza Pandemic (H1N1/09) virus was first reported in humans in Mexico in April 2009 and a pandemic level was declared on 11th of June 2009 by the World Health Organization (Chan, 2009; WHO, ...2009a). Public misconceptions about the transmission of H1N1/09 were caused by the inadequate naming of the disease as ‘swine influenza’. This cross-sectional study was conducted at the height of the outbreak in the Australian human population and before the virus was reported in the first piggery in Australia in July 2009 (OIE, 2009b; Holyoake et al., 2011). The aims of this study were to evaluate pig producers’ perceptions about the virus and the outbreak financial impact and influence on on-farm biosecurity practices. A questionnaire was designed and posted to Australian Pork Limited (APL) members (n=460), obtaining responses from 182 producers (39.6%). Pig producers had good general knowledge on potential transmission pathways for H1N1/09 between people, with direct or close contact with a sick person perceived as the most likely pathways. Changes on biosecurity practices, such as asking visitors if they had recently been overseas (27.8%) and not allowing any visitor to inspect their pigs (18.3%), were reported among respondents. In addition, approximately 40% of producers asked their employees to notify flu like symptoms, consulted a veterinarian on H1N1/09 and visited websites to seek information on H1N1/09. A higher adoption of these practices was observed among large (>100 sows) than small herds. Only 2.9% of respondents reported a reduction in pig sales during the outbreak. However, approximately one third of producers reported being financially and emotionally stressed, 38.2% were distressed about the health of their pigs and 16.7% about their own health. The most important sources of information were APL (93%), veterinarians (89%) and the state Department of Primary Industries (DPI) (75%). The first two considered the most trusted sources of information. Television, radio and other farmers were considered more important sources of information by small herds and veterinarians by larger herds. Producers believed that the H1N1/09 outbreak was better managed by the pork industry (89.9%) than by the health authorities (58.8%), and the on-going communication with APL was the main strength of the outbreak management. Communication and extension programs in future outbreaks should consider the needs of all sectors of the pig industry to increase their effectiveness.
