ABSTRACT
PURPOSE: Resistance exercise can attenuate muscular impairments associated with multiple sclerosis (MS), and blood flow restriction (BFR) may provide a viable alternative to prescribing heavy training loads. The purpose of this investigation was to examine the progression of upper and lower body low-load (30% of one-repetition maximum [1RM]) resistance training (RT) with BFR applied intermittently during the exercise intervals (RT + BFR) versus volume-matched heavy-load (65% of 1RM) RT. METHODS: Men and women with MS (n = 16) were randomly assigned to low-load RT + BFR (applied intermittently) or heavy-load RT and completed 12 weeks (2 × /week) of RT that consisted of bilateral chest press, seated row, shoulder press, leg press, leg extension, and leg curl exercises. Exercise load, tonnage, and rating of perceived exertion were assessed at baseline and every 6 weeks. RESULTS: Training load increased to a greater extent and sometimes earlier for RT + BFR (57.7-106.3%) than heavy-load RT (42.3-54.3%) during chest press, seated row, and leg curl exercises, while there were similar increases (63.5-101.1%) for shoulder press, leg extension, and leg press exercises. Exercise tonnage was greater across all exercises for RT + BFR than heavy-load RT, although tonnage only increased during the chest press (70.7-80.0%) and leg extension (89.1%) exercises. Perceptions of exertion (4.8-7.2 au) and compliance (97.9-99.0%) were similar for both interventions. CONCLUSION: The training-induced increases in load, high compliance, and moderate levels of exertion suggested that RT + BFR and heavy-load RT are viable interventions among people with MS. RT + BFR may be a preferred modality if heavy loads are not well tolerated and/or to promote early-phase training responses.
ABSTRACT
Homoleptic complexes [Fe(4bt)3](ClO4)2 (1), [Fe(2bt)3](ClO4)2 (2), and [Fe(3tpH)3](ClO4)2 (3) were obtained by a reaction between the Fe(II) precursor salt and the corresponding thiazole-based bidentate ligand (L = 4bt = 4,4'-bithiazole, 2bt = 2,2'-bithiazole, 3tpH = 3-(thiazol-2-yl)pyrazole). X-ray crystal structure determination revealed crystallization of solvent-free complex 1, a solvate 2·MeOH, and a co-crystal 3·2(3tpH). The crystal packing of all these complexes is dominated by one-dimensional interactions between the [Fe(L)3]2+ cations. These interactions are stronger in 2·MeOH and 3·2(3tpH), leading to cooperative and slightly hysteretic transitions between the high-spin and low-spin electronic configurations at â¼235 K and 159 K, respectively. In contrast, weaker intermolecular interactions in 1 result in a gradual spin crossover above 300 K, with the maximum fraction of the HS state â¼25% achieved at 400 K. Complexes 2 and 3·2(3tpH) exhibit light-induced excited spin state trapping (LIESST) under irradiation with white light or a 532 nm laser at 5 K. After the photoexcitation, the trapped metastable HS state relaxes to the ground LS state with the average relaxation temperature of 81 K and 68 K, respectively. Examination of the relaxation dynamics by optical absorption spectroscopy on a single crystal of 3·2(3tpH) revealed the sigmoidal shape of the relaxation curves at lower temperatures, attributed to cooperative effects, as well as a plateau at â¼10% of the HS fraction at intermediate temperatures, hinting at a more complex mechanism for the relaxation of the LIESST phase in this material.
ABSTRACT
BACKGROUND: There is conflicting evidence regarding the presence and magnitude of exercise-induced muscle damage (EIMD) following low-load resistance training with blood flow restriction (LL+BFR), which may be related to the protocol implemented or exercise volume. Therefore, the purpose of this investigation was to examine the effects of a 75 repetition (BFR-75) (1×30, 3×15) and four sets to volitional failure (BFR-4x) protocols on indices of EIMD among untrained men. METHODS: Twelve males with no history of lower-body resistance training during the previous six months volunteered for this investigation. One leg was randomly assigned to BFR-75, and the other to BFR-4x. Participants performed isokinetic, unilateral, concentric-eccentric, leg extension muscle actions at 30% of maximal strength with BFR. Indices of EIMD (limb circumference, perceived muscle soreness, pain pressure threshold [PPT], passive range of motion, and maximal strength [MVIC]) were recorded before exercise and 0, 24, 48, 72, and 96-hours post-exercise for each protocol. RESULTS: There were no significant changes (P>0.05) in limb circumference, PPT, passive range of motion, or MVIC. For both BFR-75 and BFR-4x, perceived muscle soreness increased (P<0.001) similarly 24- (2.5±1.7 AU) and 48-hours (1.9±1.7 AU) post-exercise. CONCLUSIONS: There was an increase in muscle soreness 24-48 hours post-exercise for both conditions, which may be due to metabolic stress, but this did not affect the force-generating capacity of the muscle (MVIC), suggesting minimal EIMD. The conflicting evidence of EIMD following LL+BFR may be related to differences in restriction time or overall exercise time.
ABSTRACT
BFR) applied during sprint interval training (SIT) on performance and neuromuscular function. METHODS: Fifteen men completed a randomized bout of SIT with CBFR, IBFR, and without BFR (No-BFR), consisting of 2, 30-s maximal sprints on a cycle ergometer with a resistance of 7.5% of body mass. Concentric peak torque (CPT), maximal voluntary isometric contraction (MVIC) torque, and muscle thickness (MT) were measured before and after SIT, including surface electromyography (sEMG) recorded during the strength assessments. Peak and mean revolutions per minute (RPM) were measured during SIT and power output was examined relative to physical working capacity at the fatigue threshold (PWCFT). RESULTS: CPT and MVIC torque decreased from pre-SIT (220.3±47.6 Nm and 355.1±72.5 Nm, respectively) to post-SIT (147.9±27.7 Nm and 252.2±45.5 Nm, respectively, all P<0.05), while MT increased (1.77±0.31 cm to 1.96±0.30 cm). sEMG mean power frequency decreased during CPT (-12.8±10.5%) and MVIC (-8.7±10.2%) muscle actions. %PWCFT was greater during No-BFR (414.2±121.9%) than CBFR (375.9±121.9%). CONCLUSION: SIT with or without BFR induced comparable alterations in neuromuscular fatigue and sprint performance across all conditions, without affecting neuromuscular function.

Objective. Surface mechanomyography (sMMG) can measure oscillations of the activated muscle fibers in three axes (i.e.X,Y, andZ-axes) and has been used to describe motor unit activation patterns (X-axis). The application of blood flow restriction (BFR) is common in exercise studies, but the cuff may restrict muscle fiber oscillations. Therefore, the purpose of this investigation was to examine the acute effects of submaximal, fatiguing exercise with and without BFR on sMMG amplitude in theX,Y, andZ-axes among female participants.Approach. Sixteen females (21 ± 1 years) performed two separate exercise bouts to volitional exhaustion that consisted of unilateral, submaximal (50% maximal voluntary isometric contraction [MVIC]) intermittent, isometric, leg extensions with and without BFR. sMMG was recorded and examined across percent time to exhaustion (%TTE) in 20% increments. Separate 2-way repeated measures ANOVA models were constructed: (condition [BFR, non-BFR]) × (time [20, 40, 60, 80, and 100% TTE]) to examine absolute (m·s-2) and normalized (% of pretest MVIC) sMMG amplitude in theX-(sMMG-X),Y-(sMMG-Y), andZ-(sMMG-Z) axes.Main results. The absolute sMMG-X amplitude responses were attenuated with the application of BFR (mean ± SD = 0.236 ± 0.138 m·s-2) relative to non-BFR (0.366 ± 0.199 m·s-2, collapsed across time) and for sMMG-Y amplitude at 60%-100% of TTE (BFR range = 0.213-0.232 m·s-2versus non-BFR = 0.313-0.445 m·s-2). Normalizing sMMG to pretest MVIC removed most, but not all the attenuation which was still evident for sMMG-Y amplitude at 100% of TTE between BFR (72.9 ± 47.2%) and non-BFR (98.9 ± 53.1%). Interestingly, sMMG-Z amplitude was not affected by the application of BFR and progressively decreased across %TTE (0.332 ± 0.167 m·s-2to 0.219 ± 0.104 m·s-2, collapsed across condition.)Significance. The application of BFR attenuated sMMG-X and sMMG-Y amplitude, although normalizing sMMG removed most of this attenuation. Unlike theXandY-axes, sMMG-Z amplitude was not affected by BFR and progressively decreased across each exercise bout potentially tracking the development of muscle fatigue.

PURPOSE: To determine the effect of playing patient-selected music intraoperatively on patient self-reported anxiety and the amount of sedative administered during cataract surgery. SETTING: Yale New Haven Hospital health system, New Haven, Connecticut. DESIGN: Prospective, randomized, controlled clinical trial. METHODS: Patients were randomized to either a music group or a control group, which had no music played. Patients were blinded to the purpose of the study. On postoperative day 1, patients were consented to participate in the study and asked to complete a 6-question Likert-style survey (modified from the State-Trait Anxiety Inventory) assessing anxiety at baseline and during surgery. Patients' intraoperative and postoperative vitals were recorded. The medication, dosage, and number of sedative injections given were also recorded. Paired t tests were used to assess for significant differences between the 2 groups. RESULTS: 107 patients (mean age 71.2 years) were enrolled in the study. There was no significant difference in baseline anxiety between the 2 groups. Patients randomized to the music group had significantly lower total self-reported anxiety (mean 5.98) than the control group (mean 7.13, P = .006). Moreover, patients exposed to music felt significantly less frightened, nervous, and confused during surgery ( P = .002, .007, and 0.017, respectively). There was no significant difference between the groups in number and dosage of sedatives given. CONCLUSIONS: Playing patient-selected music during cataract surgery is an effective way to decrease anxiety. Music directly affects patient experience and is an inexpensive, low-risk method of reducing patient anxiety during surgery.

Díaz-Loving et al. (1986) diseñaron la Escala Multi- dimensional de Empatía (EASE), un instrumento culturalmente válido para población mexicana inspirado en la estructura conceptual del Índice de Reactividad Interpersonal (IRI) (Davis, 1980). En esta investigación presentamos evidencias de validez y confiabilidad de la Escala Corta de Empatía (ECE), una versión breve de la EASE aplicada a 674 participantes (50.8 % mujeres, 49.2 % hombres) mexicanos (M = 22.8 años, de = 9.2), además del IRI, preguntas de conductas prosociales y el Inventario de Personalidad de diez ítems como criterios externos de validez. El análisis factorial exploratorio mostró tres factores malestar personal, toma de perspectiva y compasión con niveles de confiabilidad adecuados. El análisis factorial confirmatorio verificó la estructura con indicadores de bondad de ajuste aceptables, obteniendo evidencias de equivalencia estructural para mujeres y hombres. Las relaciones de los tres factores de ECE con prosocialidad, personalidad y sexo proporcionan criterios de validez externa del instrumento.
The Multidimensional Empathy Scale (EASE), a culturally valid instrument for the Mexican population inspired by the conceptual structure of the Interpersonal Reactivity Index (IRI), from 1980, was designed in 1986. The article presents evidence of the validity and reliability of the short empathy scale (ECE), a short version of the EASE, applied to 674 Mexican partici- pants (50.8 % women, 49.2 % men; M = 22.8 years, sd = 9.2). They also answered questions on prosocial behaviors and the 10-item Personality Inventory as an external validity criterion. The exploratory factor analysis showed three factors (personal discomfort, perspective-taking, and compassion) with adequate levels of reliability. The confirmatory factor analysis verified the structure with acceptable goodness-of-fit indicators, obtaining evidence of structural equivalence for women and men. The relationships of the three ECE factors with prosociality, personality, and sex provide evidence of validity.

Introduction: Soft tissue sarcomas make up 7%-15% of childhood solid tumours. The aetiology of this disease is unknown. It is a fast-growing, painless tumour; histologically similar to adult fibrosarcoma, but having a lesser risk of metastasis and a better prognosis. The treatment is aimed towards localised intervention; complete surgical resection is the appropriate treatment as long as it can be performed. Case report: An 11 years old female was referred for resection of a soft tissue tumour on the right elbow with significant peripheral vascularisation. Tumour resection was scheduled, with the placement of a partial thickness skin graft, and a piece was sent to pathology; a histological type consistent with paediatric fibrosarcoma was obtained with margins less than 1 mm from the lesion. Therefore, the patient was referred to the paediatric oncology unit. Further studies with positron emission tomography were requested, in which no evidence of macroscopic anatomy-metabolic tumour activity was found. Subsequently, treatment was started by paediatric oncology with 2 sessions of chemotherapy and 20 sessions of radiotherapy with sufficient progress; finally, assessment by plastic and reconstructive surgery was performed and an adequate quality of graft was observed, without the need for any other intervention by their service. Conclusion: The involvement of the vascular surgeon in performing the tumour resection permitted the preservation of the best circulation to the extremity, thereby, avoiding amputation. The difficult decision made by the reconstructive surgeon to place a partial thickness graft over the surgical site, and to start radiotherapy/chemotherapy by paediatric oncology, were key to the success in achieving the patient's satisfactory progress.

ABSTRACT
Antecedentes: La prevalencia mundial de discapa- cidad en adultos mayores oscila entre 29.5% y 43.4% en países de ingreso alto/bajo (OMS 2011). Objetivo: Determinar la preva- lencia de discapacidad y factores asociados en adultos mayores, Honduras, 2014-2015. Métodos: Estudio descriptivo transversal con análisis de asociación. Estudiantes de último año, Carrera de Medicina, Universidad Nacional Autónoma de Honduras, realizaron búsqueda activa de 50 participantes ≥60 años de edad. Se aplicaron dos instrumentos, uno para búsqueda activa y otro para caracterizar al participante con/sin discapacidad permanente ≥1 año de evolu- ción. Se evaluó limitación de actividad y restricción de participación ≤30 días utilizando la Clasiicación Internacional del Funcionamien- to, Discapacidad y Salud (CIF) y cuestionario WHODAS 2.0 (OMS). Se realizó análisis univariado (frecuencias, porcentajes, prevalen- cias, IC95%) y análisis bivariado (diferencia de proporciones); valor p<0.05 se consideró signiicativo). Resultados: De un total de 5,126 participantes ≥60 años de edad, 3,017 (58.9%) mujeres, edad pro- medio 73.6 años (rango 60-106), la prevalencia de discapacidad fue 51.2% (2,627/5,126); discapacidad grado leve se presentó en 1,893 (72.1%). Las estructuras relacionadas con movimiento (75.5%) y función esquelética (72.6%) fueron las más afectadas. La limitación de moverse (93.4%) y la restricción en invertir dinero propio y fami- liar en su estado de salud (86.8%) fueron las más frecuentes. Los factores sexo femenino, edad>70 años, escolaridad <6 años, enfer- medades crónicas, trauma, accidente o violencia podrían estar aso- ciados a discapacidad; todos p<0.01. Discusión: La discapacidad en adultos mayores se asoció a algunas condiciones prevenibles. Es apremiante implementar programas de envejecimiento saludable en Honduras...(AU)

ABSTRACT Introduction. In Peru, breast cancer represents the most common type of cancer in women and the sixth most lethal type of cancer in the general population. Overexpression of the epidermal growth factor receptor (HER2 +) occurs in 20% to 30% of breast cancers, and is associated with more aggressive tumors, with greater recurrence and greater mortality. Objective. Prepare a set of evidence-based recommendations for the diagnosis and treatment of HER2 + breast cancer, in order to help reduce mortality, disease progression and improve quality of life. Methods. A panel of clinical specialists and methodologists was formed, who identified relevant clinical questions about the diagnosis and treatment of HER2 + breast cancer. A systematic search for CPGs was carried out in Medline (PubMed), and in developing and compiling agencies. For the formulation of recommendations, the panel of specialists discussed the evidence and elements of the context of implementation of the recommendation, following the methodology proposed by the Ministry of Health of Peru. Results. Nine clinical questions were prioritized. A total of 25 clinical recommendations were made. Conclusions. An evidence-based CPG was developed through a systematic, rigorous and transparent process developed by a multidisciplinary team.
ABSTRACT
Las Premisas Histórico-Socioculturales (PHSC) son normas y creencias que regulan el comportamiento de cada cultura. En México, una premisa de cómo deben conducirse las parejas es "El compromiso da formalidad a la relación de pareja". Sin embargo, los individuos no reciben pasivamente las PHSC, las modifican o las contradicen con sus acciones lo que puede crear disonancia cognoscitiva. Entonces, la disonancia ocurre cuando coexisten dos cogniciones incongruentes en un individuo, lo que puede ocurrir por la llegada de nueva información o por trasgredir una norma cultural. El objetivo del estudio fue comprobar si la opinión contra actitudinal sobre PHSC acerca del compromiso en las relaciones de pareja ocasiona disonancia cognoscitiva en los individuos, medida como ansiedad. Se diseñó un experimento donde se manipuló la PHSC sobre la relación de pareja que los individuos recibían y el estatus de la fuente proveniente: 2 (PHSC: Concordante/ Contra actitudinal) × 2 (Fuente de alto o bajo estatus). Como variable dependiente se midió la ansiedad estado y como covariable el nivel de compromiso en su relación de pareja. Participaron 41 individuos. Los resultados muestran que el grupo de fuente de bajo estatus y PHSC concordante tuvo más preocupación, mientras que los que recibieron una PHSC contra actitudinal estuvieron más tranquilos. En el primer grupo se creó disonancia debido a dos cogniciones incongruentes: nivel educativo y pensar igual que una fuente de bajo estatus, lo que afectó su autoconcepto; mientras que la condición de artículo de alto estatus no generó diferencias
Historical Sociocultural Premises (PHSCs) are norms and beliefs that regulate the behavior of each culture. A premise for Mexican couples is that "Commitment gives formality to couple relationships". However, individuals do not passively receive PHSCs, they modify or contradict them with their actions, which can lead to cognitive dissonance. So, dissonance occurs when two incongruous cognitions coexist in an individual, caused by either receiving new information or transgressing a cultural norm. The objective of the study is in order to verify if counter attitudinal opinions on PHSCs about commitment in couple relationships cause cognitive dissonance in individuals, measured as anxiety. We designed an experiment where we manipulated the PHSCs about couple relationships that individuals received, and the status of the source they came from: 2 (PHSC: Concordant / Counter attitudinal) × 2 (High and low status sources). We measured state anxiety as a dependent variable and the participants' level of commitment in their couple relationship as a covariate. 41 individuals participated. The results of this research showed that, in the low status source group, participants with a concordant PHSC were more worried, while those who received a counter attitudinal PHSC were calmer. In the first group, there was dissonance due to two incongruous cognitions (educational level and thinking like a low status source), which affected their self concept, while the condition of high status article did not generate any differences

Abstract The relationship between dimensions of self-construal and reported mood states is examined among two samples of Mexican students. Scales focused on seven different aspects of self-construal were employed. Respondents favored predominantly individualistic ways of describing themselves, but also scored high on connection to others. These effects were particularly strong among respondents from Tijuana when compared with those from Mexico City. Depressive mood state was predicted by higher self-reported connection with others, commitment to others, receptiveness to influence and behavioral variability. High self-esteem was predicted by higher self-reported consistency, self-orientation, self-direction and expressiveness.
Resumen La relación entre las dimensiones de la autodefinición y los estados de ánimo auto-reportados fueron evaluados en dos muestras de estudiantes mexicanos. Las escalas que se emplearon se enfocaron en siete diferentes aspectos de la auto-definición. Las respuestas de los participantes favorecieron predominantemente maneras individualistas de describirse a sí mismos, aunque también puntuaron alto en mediciones de conexión con los demás. Estos efectos son particularmente fuertes en los participantes de Tijuana cuando se comparan con los de Ciudad de México. Estados de ánimo depresivos fueron predichos por altos niveles auto-reportados de conexión con otros, compromiso con otros, receptividad a la influencia, y variabilidad conductual. Alta autoestima fue predicha por alta consistencia auto-reportada, auto-orientación, auto-dirección y expresividad.
ABSTRACT
El Glioblastoma Multiforme (GBM) es el tumor cerebral primario más común en los adultos, la metástasis extra-craneal de GBM detectada clínicamente es bastante rara, debido a la ausencia de linfáticos en el cerebro y a la dificultad de los tumores en penetrar los vasos sanguíneos. Se producen entre el 0,2 a 2% según 10 reportado en la literatura disponible. Se reporta un caso de rara presentación de una paciente de 53 añ os con diagnóstico de Glioblastoma multiforme localizado en región interparietal derecha y otra lesion en region fronto-parietal derecha (multifocal). Se le realiza biopsia estereotáxica para diagnóstico y recibio tratamiento con radioterapia conformada en 3D al primario. Posteriormente a los 2 meses presenta metástasis linfática en ganglio cervical derecho, diagnosticado por citología y biopsia incisional. Así mismo se realiza revisión de la literatura. Se discuten el impacto de la cirugía en la diseminación tumoral y las posibles vías de diseminación.
Glioblastoma multiforme (GBM) is the most common and most aggressive primary brain tumor in adults. The presence of extra-cranial GBM metastasis is very rare, because the absence of brain lympha- tics and the difficulty of tumors cells to penetrate into blood vessels, occurring only between 0.2 to 2% of the cases reported in the available literature. A case of extreme rarity is presented: A female 53 year old patient, with diagnosis ofGliobastoma multiforme localized in the right interparietal region and another lesion in the rightfrontal-parietal region (multifocal). She underwent diagnostic stereotactic biopsy and was treated with 3D conformal radiotherapy in the primary. Two months later the patient presents lymphatic metastasis in the right cervical lymph node, diagnosed by cytology and incisional biopsy. A review of the literature is presented. The impacts of surgery in tumor dissemination and possible tumor dissemination schemes are discussed.

El Instrumento de Temor a la Evaluación Social Negativa (ITESN) ha mostrado evidencias de validez y confiabilidad al utilizarse en muestras culturalmente distintas y al traducirse a diferentes idiomas (Duke et al., 2006; Gallego, 2010; Gallego et al., 2007; Weeks et al., 2005; Tavoli et al., 2009). Dada la relevancia del estudio de la ansiedad y fobia social, y con la intención de aportar herramientas para estudiar estas variables en muestras mexicanas, este proyecto presenta evidencias de validez y confiabilidad de una traducción al castellano del ITESN (Leary, 1983) en una muestra de estudiantes universitarios de Ciudad de México. Se realizaron análisis de discriminación de reactivos, factoriales exploratorios y factoriales confirmatorios mediante modelamiento de ecuaciones estructurales. Los resultados muestran una estructura unifactorial que agrupa ocho de los doce reactivos del instrumento original, explica el 53.8 % de la varianza total y muestra consistencia interna adecuada (α = 0.88). Se obtienen evidencias de validez de criterio del ITESN, así: a) se asocia positivamente con el Instrumento de Ansiedad Rasgo y b) mediante un procedimiento experimental, se observan asociaciones positivas entre el ITESN y mediciones de ansiedad estado y motivación de autopresentación ante la expectativa de conocer a otra persona. Se discute el funcionamiento de los cuatro reactivos redactados de forma negativa y la interpretación teórica de las relaciones que respaldan la validez de criterio.
The Brief fear of Negative Evaluation Scale (BFNE) has shown good validity and reliability properties in different cultural samples, as well as when it has been translated to other languages (Duke et al., 2006; Gallego, 2010; Gallego et al., 2007; Weeks et al., 2005; Tavoli et al., 2009). Given the relevance of the study of anxiety and social phobia and the need for research tools for Mexican samples, this study presents validity and reliability evidences for a translation to Spanish language of the BFNE (Leary, 1983) in a sample of undergraduate students from Mexico City. Psychometric tests included discrimination analysis for each item, principal component factorial analysis, and confirmatory factor analysis through structural equation modeling. Results show a one factor structure with just eight of the 12 original items. It explains 53.8% of total variance and has good reliability ( α = 0.88). In addition, evidence was found concerning criterion validity for the BFNE: a) It correlates positively with a Trait Anxiety Scale; and b) through an experimental procedure, positive correlations for the BFNE with a State Anxiety Scale and a Self-Presentation Motivation Scale when participants had the expectation of being introduced to another person. The discussion verses in relation to the performance of score reversed items and the theoretical meaning of items and to the observed relationships that support the criterion validity of this translation to Spanish language of the BFNE scale.

Objetivos. Determinar la diversidad genética de aislamientos peruanos de Leptospira spp. mediante electroforesis en gel de campo pulsado (PFGE). Materiales y métodos. Se estandarizó la metodología de PFGE propuesta por Galloway y Levett (2008). Se elaboró una base de datos con los perfiles de PFGE de 65 cepas de referencia y se aplicó la técnica en 111 aislamientos de Leptospira spp. obtenidos en Perú entre 2002 y 2010. Resultados. Se determinó gran diversidad genética de serovares de Leptospira spp. circulantes en nuestro país. Se identificaron 57 serovares, 47 en 97 aislamientos patógenos. Los serovares más frecuentes fueron Icterohaemorrhagiae/Copenhageni (n=24) y Canicola (n=7). Las especies más frecuentes fueron L. santarosai (49,5%) y L. interrogans (37,1%). La distribución de especies, clusters y serovares varió según la fuente del aislamiento, el contexto ambiental y la procedencia. Conclusiones. Existe gran diversidad de serovares circulantes en el Perú, la cual está relacionada a la especie, el reservorio, el contexto ambiental y la procedencia del aislamiento. Se evidencia las relaciones genéticas y epidemiológicas entre aislamientos de diferentes fuentes, lo cual está relacionada a la especie, el reservorio, el contexto ambiental y la procedencia del aislamiento.
Objectives. Determine the genetic diversity of Peruvian isolations of Leptospira spp. through Pulsed Field Gel Electrophoresis (PFGE). Materials and methods. The PFGE methodology proposed by Galloway and Levett (2008) was standardized. A database including the PFGE profiles of 65 reference strains was prepared, and the technique was applied in 111 isolates of Leptospira spp. obtained in Peru between 2002 and 2010. Results. A great generic diversity of serovars of circulating Leptospira spp. was determined in our country. 57 serovars were identified, 47 out of 97 pathogen isolates. Most frequent serovars were Icterohaemorrhagiae/Copenhageni (n=24) and Canicola (n=7). The most frequent species were L. santarosai (49,5%) and L. interrogans (37,1%). The distribution of species, clusters and serovars changed according to the source of isolate, the environmental context and the origin. Conclusions. There is great diversity of circulating serovars in Peru. There are genetic and epidemiological relations among isolates of different sources, and this is related to species, reservoir, environmental context and the origin of the isolate.
