El desentrenamiento deportivo en el boxeo

La preparación del boxeador conlleva cambios y adaptaciones fisiológicas para garantizar las cargas físicas, psíquicas y sociales a las que han sido sometidos sus practicantes. Finalizada dicha etapa aparece el desentrenamiento deportivo, cuya naturaleza es eminentemente pedagógica y consiste en desinstalar los componentes que garantizaron la acumulación de cargas durante su etapa como boxeador activo, hasta alcanzar los niveles de un practicante sistemático normal de la Cultura Física. El objetivo de este trabajo consistió en diseñar una estrategia pedagógica sustentada en un modelo de igual naturaleza para el desentrenamiento potenciado con la equino-interacción-profiláctica, a partir del uso de ejercicios con caballos como elemento de cambio. Se utilizaron como métodos empíricos y técnicas la observación de las sesiones de deportivo, el análisis de documentos, la encuesta a exboxeadores, entrenadores, médicos deportivos, funcionarios y expertos seleccionados, así como los talleres de opinión crítica y socialización entre entrenadores de boxeo. Como resultados se obtuvo un modelo pedagógico del que se derivó una estrategia. Estos aportes fueron constatados mediante la aplicación parcial de la estrategia en un combinado deportivo en Majibacoa, Las Tunas y se demostró su factibilidad para ser generalizada. El artículo que se ofrece tiene como objetivo socializar resultados de la investigación realizada sobre el desentrenamiento deportivo en el boxeo potenciado con el equino-interacción-profiláctica. De manera conclusiva, los aportes teórico y práctico demostraron el cumplimiento del objetivo de la investigación y la solución del problema científico.

A preparação do boxeador implica em mudanças e adaptações fisiológicas para garantir as cargas físicas, psicológicas e sociais às quais o boxeador foi submetido. Ao final dessa etapa, surge o destreinamento esportivo, cuja natureza é eminentemente pedagógica e consiste em desinstalar os componentes que garantiram o acúmulo de cargas durante sua etapa como boxeador ativo, até atingir os níveis de um praticante normal sistemático de Cultura Física. O objetivo deste trabalho consistiu em projetar uma estratégia pedagógica baseada em um modelo semelhante de destreinamento aprimorado com a interação equino-profilática, baseada no uso de exercícios com cavalos como elemento de mudança. Os métodos e técnicas empíricos utilizados foram a observação de sessões esportivas, a análise de documentos, pesquisas com ex-pugilistas, treinadores, médicos esportivos, oficiais e especialistas selecionados, bem como workshops de opinião crítica e socialização entre treinadores de boxe. Como resultado, foi obtido um modelo pedagógico do qual derivou uma estratégia. Essas contribuições foram confirmadas por meio da aplicação parcial da estratégia em uma equipe esportiva em Majibacoa, Las Tunas, e sua viabilidade de generalização foi demonstrada. O objetivo deste artigo é socializar os resultados da pesquisa realizada sobre o destreinamento esportivo no boxe, aprimorado com a interação equino-profilática. Em conclusão, as contribuições teóricas e práticas demonstraram o cumprimento do objetivo da pesquisa e a solução do problema científico.

The preparation of the boxer entails physiological changes and adaptations to guarantee the physical, psychological and social loads to which its practitioners have been subjected. Once this stage is completed, sports detraining appears, the nature of which is eminently pedagogical and consists of uninstalling the components that guaranteed the accumulation of loads during his time as an active boxer, until reaching the levels of a normal systematic practitioner of Physical Culture. The objective of this work was to design a pedagogical strategy based on a model of the same nature for detraining enhanced with equine-interaction-prophylactics, based on the use of exercises with horses as an element of change. Observation of sports sessions, document analysis, a survey of former boxers, coaches, sports doctors, officials and selected experts, as well as critical opinion and socialization workshops among boxing coaches, were used as empirical methods and techniques. As results, a pedagogical model was obtained from which a strategy was derived. These contributions were verified through the partial application of the strategy in a sports complex in Majibacoa, Las Tunas and its feasibility to be generalized was demonstrated. The article offered aims to socialize results of the research carried out on sports detraining in boxing enhanced with equine-interaction-prophylaxis. Conclusively, the theoretical and practical contributions demonstrated the fulfillment of the research objective and the solution of the scientific problem.

A model and a physical-therapeutic orientation strategy for people with phase III chronic ischemic heart disease were developed. It was concluded that the actions designed in the strategy facilitated the preparation of these patients, with a view to their social and work reintegration.

New enzyme-linked immunoassay for the detection of specific antibodies against multiple Leptospira serogroups in bovine sera.

Leptospirosis is a zoonotic disease with worldwide endemicity in Argentina, it is a significant public health problem in low-income populations. Bovine leptospirosis is a serious economic problem for cattle production, causing abortions, reduced milk yield, mortality in calves and decreased daily weight gain. We developed an enzyme-linked immunosorbent assay (ELISA) with sonicated Leptospira interrogans serogroup Icterohaemorrhagiae serovar Copenhageni M 20. We evaluated its performance for the detection of specific antibodies against multiple Leptospira serogroups in bovine. The microscopic agglutination test (MAT) was used as the gold standard. The performance of this ELISA was evaluated with a panel of sera (118 MAT confirmed positive and 97 MAT negative). The overall sensitivity was close to 85.6 % and the specificity was 83.5 %, according to the MAT reference method. Analytical specificity of the IgG-ELISA was evaluated using 50 bovine serum samples from animals showing serum antibodies against other pathogens that cause abortion in bovine, such as Brucella sp., Neospora sp. and Bovine Viral Diarrhea (BVD), and no cross-reaction was observed. This IgG-ELISA can be an alternative to the MAT for diagnosis of leptospiral infection in bovine.

Anesthetic Management of an Infant With Kleefstra Syndrome During Direct Laryngoscopy and Rigid Bronchoscopy: A Case Report.

Kleefstra syndrome (KS) is an autosomal dominant disorder caused by a chromosomal deletion at 9q34.3 resulting in pathogenic variants of the gene that codes for the enzyme, euchromatin histone methyltransferase 1 (EHMT1). KS is a rare, yet clinically relevant congenital disorder for anesthesiologists because of its potential for cardiac and craniofacial involvement. We present a 3-month-old patient with KS who required anesthetic care for diagnostic laryngoscopy and rigid bronchoscopy. The end-organ effects of KS are reviewed and our anesthetic care presented.

Regional Anesthesia for Pain Management After Orthopedic Procedures for Treatment of Lower Extremity Length Discrepancy.

INTRODUCTION: The use of regional anesthesia techniques continues to expand in a wide variety of surgical procedures as the benefits and safety are increasingly appreciated. Limb-lengthening procedures are often associated with significant postoperative pain and high opioid requirements which may impact patient's recovery and increase risk of chronic pain and long-term opioid use. METHODS: The current study retrospectively reviews our experience utilizing a novel peripheral nerve catheter (PNC) protocol for postoperative pain management in patients undergoing elective limb-lengthening procedures. We measure total opioid consumption following 48 hrs in the postoperative period between groups. RESULTS: A total of 70 patients were included from which 41 received general plus regional anesthesia (RA) and 29 were managed with general anesthesia alone (NORA). Postoperative pain needs were calculated as morphine equivalents (ME). There were no differences in the demographic characteristics between the groups. Over the first 48 postoperative hours, opioid use was 0.5 mg/kg ME (IQR 0.3, 0.9) in the RA group versus 1.7 mg/kg ME (IQR 1.1, 3.1) in the NORA group (p<0.001). Subgroup analysis between femoral lengthening and tibial-fibular lengthening procedures demonstrated the same opioid-sparing effect favoring the RA group compared to the NORA group. Hospital length of stay was significantly shorter in the femoral lengthening RA group compared to NORA group (32 hrs [IQR 29, 35] versus 53 hrs [IQR 33, 55], respectively). There was no significant difference in length of stay between the RA group and NORA group after tibial-fibular lengthening procedures. DISCUSSION: Regional anesthesia via continuous catheter infusions has a clinically significant opioid-sparing effect for postoperative pain management after limb-lengthening procedures and may facilitate earlier hospital discharge.

One-Year Follow-Up Results From the Observational, Multicenter, Prospective, and Controlled Registry: The WALTZ All-Comers Study.

The aim of this study was to evaluate 1-year follow-up results in an all "comers" population treated with a new cobalt chromium bare-metal stent (BMS) design. Since August 2016 to March 2017, 201 (9.7% of screening population) consecutive patients undergoing coronary stent implantation in 11 centers in Argentina were prospectively included in our registry. The inclusion criteria were multiple-vessel disease and/or unprotected left main disease, acute coronary syndromes (ACS) with at least one severe (⩾70%) stenosis in any of major epicardial vessel. In-stent restenosis, protected left main stenosis, or impossibility to receive dual-antiplatelet therapy was an exclusion criterion. Major adverse cardiac events (MACE) were the primary endpoint and included cardiac death, myocardial infarction (MI), and target lesion revascularization (TLR); also, all components of the primary endpoint were separately analyzed. Completeness of revascularization was analyzed as post hoc data using residual SYNTAX or ERACI risk scores. Demographic characteristics showed that 6.5% of patients were very elderly, 22.5% have diabetes, 47% have multiple-vessel disease, 67% have ACS, and 32% have ST elevation MI. At a mean of 376 ± 18.1 days of follow-up, MACE was observed in 10.4% of patients: death + MI + cardiovascular accident (CVA) in 3% (6 of 201) and cardiac death + MI + CVA in 1.5% (3 of 201). Residual ERACI score ⩽5 was associated with 98% of event-free survival (P < .04). In conclusion, this prospective, multicenter, and observational all-comers registry with this novel BMS design showed a low incidence of adverse events at 1 year mainly due to coronary restenosis.

[Differentiation of pathogenic leptospires spp by PCR of ligB gene and sequencing]. / Diferenciación de serovares de leptospiras patógenas mediante PCR del gen ligB y secuenciación.

Leptospirosis is a zoonosis having worldwide distribution. The objective of this work was to develop a molecular technique to differentiate pathogenic Leptospira spp. A region of adhesin ligB, present only in the pathogenic species was amplified by PCR and sequenced. ligBRpet and ligBFpet primers were used, which amplified the target DNA from pathogenic L. interrogans reference strains serovars Pomona strain Pomona, Canicola strain Hond Utrecht IV, Copenhageni strain M 20, Wolffi strain 3705, Pyrogenes strain Salinem, Hardjo strain Hardjoprajitmo, L. borgpetersenii serovar Castellonis strain Castellon 3 and 4 pathogenic strains isolated from bovines, pigs, rats and opossums. L. biflexa serovars Patoc strain Patoc I and Andamana strain Andamana were not amplified. Sequencing of the amplified products exhibited sufficient variation among serovars, which differentiates them.

El proceso de formación de los jóvenes universitarios en la concepción de educación de género y valores cívicos / The process of the university youths' training on gender education and civic values

La cultura es el resultado de la aprehensión por parte del individuo de las influencias de cada contexto donde se ubica y se establecen las manifestaciones identitarias socioculturales de su grupo y, además, las de género, derivadas de los procesos formativos en diversas instituciones. Las universidades en Cuba tienen el compromiso de formar hombres con una elevada cultura profesional y general que le permita adoptar una actitud transformadora ante los retos de la nueva sociedad y comportamientos responsables en todas las esferas de la vida; sin embargo, de acuerdo con las observaciones, los intercambios y la práctica profesional, no siempre se revelan conductas adecuadas, por lo que en este trabajo se ofrecen algunas consideraciones en torno a la expresión de la identidad de género y los valores cívicos, como resultados de la asimilación de pautas establecidas en los ambientes donde se desarrollan los estudiantes universitarios

Culture is the result of the apprehension by the individual of the influences of each context where the social and cultural identity manifestations are established and besides, those of gender, derived from the training processes in several institutions. Universities in Cuba have the commitment of training men with a high professional and general culture that allows them to adopt a transforming attitude when facing the challenges of the new society and responsible behaviors in all the spheres of the life; however, according to observations, exchanges and professional practice, appropriate behaviors are not always exposed, so that some considerations regarding the expression of gender identity and the civic values are exposed in this work, as results of the assimilation of rules settled down in the environment where the university students are trained

Isolation of a Seawater Tolerant Leptospira spp. from a Southern Right Whale (Eubalaena australis).

Leptospirosis is the most widespread zoonotic disease in the world. It is caused by pathogenic spirochetes of the genus Leptospira spp. and is maintained in nature through chronic renal infection of carrier animals. Rodents and other small mammals are the main reservoirs. Information on leptospirosis in marine mammals is scarce; however, cases of leptospirosis have been documented in pinniped populations from the Pacific coast of North America from southern California to British Columbia. We report the isolation of a Leptospira spp. strain, here named Manara, from a kidney sample obtained from a Southern Right Whale (Eubalaena australis) calf, which stranded dead in Playa Manara, Península Valdés, Argentina. This strain showed motility and morphology typical of the genus Leptospira spp. under dark-field microscopy; and grew in Ellinghausen-McCullough-Johnson-Harris (EMJH) medium and Fletcher medium after 90 days of incubation at 28°C. Considering the source of this bacterium, we tested its ability to grow in Fletcher medium diluted with seawater at different percentages (1%, 3%, 5%, 7% and 10% v/v). Bacterial growth was detected 48 h after inoculation of Fletcher medium supplemented with 5% sea water, demonstrating the halophilic nature of the strain Manara. Phylogenetic analysis of 16S rRNA gene sequences placed this novel strain within the radiation of the pathogenic species of the genus Leptospira spp., with sequence similarities within the range 97-100%, and closely related to L. interrogans. Two different PCR protocols targeting genus-specific pathogenic genes (G1-G2, B64I-B64II and LigB) gave positive results, which indicates that the strain Manara is likely pathogenic. Further studies are needed to confirm this possibility as well as determine its serogroup. These results could modify our understanding of the epidemiology of this zoonosis. Until now, the resistance and ability to grow in seawater for long periods of time had been proven for the strain Muggia of L. biflexa, a saprophytic species. To the best of our knowledge, this is the first isolation of a Leptospira sp. from cetaceans. Our phenotypic data indicate that strain Manara represents a novel species of the genus Leptospira, for which the name Leptospira brihuegai sp. nov. is proposed.

Genotypes of Leptospira spp. strains isolated from dogs in Buenos Aires, Argentina.

Leptospirosis is an infectious disease of wide global distribution, which is endemic in Argentina. The objective of this study was to obtain the genetic profiles of Leptospira spp. strains isolated from clinical cases of dogs in the province of Buenos Aires by the multiple-locus variable-number tandem repeat analysis (MLVA). Eight isolated canine strains were genotyped by MLVA, obtaining the identical profile of Leptospira interrogans serovar Canicola Hond Utrecht IV in the strains named Dogy and Mayo. The strains named Bel, Sarmiento, La Plata 4581 and La Plata 5478 were identical to the profile of the genotype of L. interrogans serovar Portlandvere MY 1039.The strain named Avellaneda was identical to the genotype profile of L. interrogans serovar Icterohaemorrhagiae RGA and the strain named SB had the same profile as the L. interrogans serovar Pomona Baires genotype and was similar to the profile of serovar Pomona Pomona genotype. It would be useful to include a larger number of isolates from different dog populations in various provinces of Argentina and to characterize the genetic profiles of the strains circulating in the country. The information obtained will be useful for the control of leptospirosis in the dog population.

MRSA Pediatric clone expressing ermC plus lnuA genes causing nosocomial transmission and healthcare workers colonization in a neonatal intensive care unit.

Methicillin-resistant Staphylococcus aureus (MRSA) is a major cause of both nosocomial and community-acquired infections. We describe an outbreak caused by the MRSA Pediatric clone expressing an unusual lincosamide resistant phenotype. Between January and May 2006, an MRSA outbreak was detected at the Neonatal Unit of Hospital Interzonal General de Agudos "Evita", Buenos Aires Province, Argentina that affected ten patients. Seven isolates from seven patients plus five MRSA recovered from health care workers (nasal carriage) were studied. Two phenotypes were observed: (i) ELCi (10), resistance to erythromycin and lincomycin and inducible resistance to clindamycin; (ii) ELiCi (2), resistance to erythromycin and inducible resistance to lincomycin and clindamycin. All 12 MRSA were resistant to oxacillin, erythromycin and gentamicin. Isolates expressing the ELCi-phenotype showed lincomycin MIC values between 16 and 32mg/L, while the remaining 2 isolates with ELiCi-phenotype presented a MIC value of 0.5mg/L. No differences were observed between the clindamycin MIC values in both phenotypes, ranging 0.25-0.5mg/L. Isolates showing ELCi-phenotype harbored ermC plus lnuA genes, and the other two only ermC gene. All 12 isolates were genetically related and belonged to the Pediatric clone (ST100) harboring a new variant of SCCmecIV. This is the first MRSA outbreak expressing an unusual ELCi phenotype due to a combination of ermC plus lnuA genes.

Genotypes of pathogenic Leptospira spp isolated from rodents in Argentina

Leptospirosis is the most widespread zoonosis in the world and significant efforts have been made to determine and classify pathogenic Leptospira strains. This zoonosis is maintained in nature through chronic renal infections of carrier animals, with rodents and other small mammals serving as the most important reservoirs. Additionally, domestic animals, such as livestock and dogs, are significant sources of human infection. In this study, a multiple-locus variable-number tandem repeat analysis (MLVA) was applied to genotype 22 pathogenic Leptospira strains isolated from urban and periurban rodent populations from different regions of Argentina. Three MLVA profiles were identified in strains belonging to the species Leptospira interrogans (serovars Icterohaemorrhagiae and Canicola); one profile was observed in serovar Icterohaemorrhagiae and two MLVA profiles were observed in isolates of serovars Canicola and Portlandvere. All strains belonging to Leptospira borgpetersenii serovar Castellonis exhibited the same MLVA profile. Four different genotypes were isolated from urban populations of rodents, including both mice and rats and two different genotypes were isolated from periurban populations.

[Adaptation of an immunohistochemistry protocol for the detection of Leptospira spp. in samples of formaldehyde-fixed tissue]. / Adaptación de un protocolo de inmunohistoquímica para la detección de Leptospira spp. en muestras de tejido fijado en formaldehído.

The immunohistochemistry technique was evaluated in tissue samples fixed in formaldehyde saline solution 10 % and included in paraffin to be used as a lab method allowing to identify leptospires in tissues. Samples obtained from the experimental inoculation of 8 guinea pigs carriers of L. interrogans Pomona isolated from a clinical case were used. The disease was reproduced in a lab model. The histologic sections of the kidneys of the animals inoculated were subjected to histopathological studies, immunofluorescence, Warthin-Starry stain, and immunohistochemistry technique using formaldehyde-fixed samples. This technique proved to be an efficient tool for the diagnosis of leptospirosis.
