ABSTRACT: Fascioliasis is a widely distributed parasitic zoonosis caused by the trematode Fasciola hepatica that affects livestock production and generates high economic losses. In Chilean authorised abattoirs, the infected livestock livers are condemned during the veterinary inspection. This study aims to evaluate the prevalence of fascioliasis in Chile from 2014 to 2016 and also monthly from 2002 to 2015 in livestock (cattle, pig, sheep, horse and goat) slaughtered in abattoirs of La Araucanía region, southern Chile. To do this, the available records on abattoirs provided by the sanitary authority were analysed. A descriptive statistics and trend analysis of the data by jointpoint regression was carried out. The Biobío and La Araucanía regions registered the highest levels of parasitosis in the country recording levels of 59.18 and 44.74%, respectively, and presented 50.03% of the liver condemnation rate in cattle. During the study period, a total of 2,239,164 animals were slaughtered and 40.59% infected livers with F. hepatica were condemned in the 9 existing abattoirs of La Araucanía region. The abattoirs located in the cities of Temuco (51.43%) and Angol (65.09%) recorded the highest percentages of fascioliasis. The cattle species recorded the highest number of slaughtered animals and liver condemnation (54.52%). The presence of the parasite was recorded annually and monthly and it was possible to observe a slight increase in fascioliasis over the years. This study provides updated information on the fascioliasis prevalence in the country and the dynamics of condemnation in endemic areas such as La Araucanía region, which could contribute to the control and prevention of this zoonosis.

Abstract Objective. This work sought to determine the perception of behaviors of humanized nursing care and its relation with sociodemographic and clinical variables in patients hospitalized in a Hemato-Oncology Department. Methods. Analytic cross-sectional study conducted with 51 patients hospitalized in the Hemato-Oncology Unit at Hospital Base Valdivia, Chile. A survey containing sociodemographic and clinical information was applied together with the questionnaire on Perception of Behaviors of Humanized Nursing Care 3 rd version” -PBHNC 3v (32 items distributed in the categories: Qualities of nursing work, Openness to nurse-patient communication, and Willingness to care). Results. Of the participants, 51% were women, with mean age of 46.5±16.6 years; 54.9% were diagnosed with Lymphoma and 78.4% were in the treatment induction stage. In 30 of the 32 items of the instrument, > 90% of the participants evaluated compliance with the behavior of caring at level of “always”. By categories, it was observed that for “Willingness to care” there was significantly lower score among patients from 18 to 49 years of age (p=0.0455). For the category “Openness to nurse-patient communication” lower median score existed in patients with Myeloma (p=0.0043) and in patients in the Remission-Consolidation stage (p=0.0084). Days of hospitalization were associated significantly with the category “Willingness to care”, being lower with 16 days and more (p=0.0242). Conclusion. High frequency was observed of humanized-care behaviors and small differences in their assessment that were associated with demographic factors like age, and clinical factors, like diagnosis, treatment stage, and days of hospitalization.

Abstract Background: Chlamydia trachomatis is recognized as the causative agent of one of the most common and curable sexually transmitted infections (STIs). In women, it can be a trigger for pelvic inflammatory disease, a risk factor for infertility or acquisition of other STIs. Aim: To determine CT in women with vaginitis and associate it with sociodemographic, sexual, clinical, and vaginal microbiota factors. Methods: 121 female volunteers > 18 years of age, with a clinical diagnosis of vaginitis and abnormal vaginal discharge, attending in primary health care services (PHC) in Temuco-Chile were recluted. A vaginal discharge sample was taken, determining C. trachomatis by polymerase chain reaction and vaginal microbiota by Gram stain. Clinical, sociodemographic and sexual data were collected by survey. Results: Age range was 18-61 years. The frequency of C. trachomatis was 14.9%. C. trachomatis was associated with a higher number of sexual partners in the last 5 years (p = 0.001), oral plus anal sex (p = 0.055) and sex toys (p = 0.027); there was a non-significant association with bacterial vaginosis 31.2% (p = 0.091) and initiation of sexual activity < 18 years 20.6% (p = 0.07). Conclusions: It would be beneficial to incorporate in the gynecological semiology of the women attended in PHC services, the factors found to favor C. trachomatis infection, as this could help the management of this STI.

Resumen Introducción: Chlamydia trachomatis es reconocida como el agente causal de una de las infecciones de transmisión sexual (ITS) más común y curable. En mujeres, puede ser gatillante de enfermedad inflamatoria pélvica, un factor de riesgo para infertilidad o adquisición de otras ITS. Objetivo: Determinar C. trachomatis en mujeres con diagnóstico clínico de vaginitis asociando factores sociodemográficos, sexuales, clínicos y microbiota vaginal. Pacientes y Métodos: Participaron 121 mujeres voluntarias > 18 años, con diagnóstico clínico de vaginitis y descarga vaginal anormal, atendidas en servicios de atención primaria en salud (APS) en Temuco-Chile. Se tomó muestra de flujo vaginal, determinándose C. trachomatis por una reacción de polimerasa en cadena convencional y microbiota vaginal por tinción de Gram. Se colectaron datos clínicos, sociodemográficos y sexuales mediante encuesta. Resultados: Rango de edad 18-61 años. La frecuencia de C. trachomatis fue 14,9%. Se asoció C. trachomatis a mayor número de parejas sexuales en los últimos 5 años (p = 0,001), relaciones sexuales oral más anal (p = 0,055) y juguetes sexuales (p = 0,027). Asociación no significativa hubo con vaginosis bacteriana 31,2% (p = 0,091) e inicio de la actividad sexual < 18 años 20,6% (p = 0,07). Conclusiones: Sería beneficioso incorporar en la semiología ginecológica de las mujeres atendidas en servicios de APS, los factores encontrados como favorecedores de infección por C. trachomatis, pues ello podría ayudar al manejo de esta ITS.

Resumo Objetivo Determinar a concordância entre o diagnóstico clínico de mulheres com corrimento vaginal anormal (AVD) e os resultados laboratoriais por meio da detecção molecular e observação da microbiota vaginal. Métodos Estudo transversal realizado em 2018 em Temuco, Chile. Participaram 25 parteiras de 12 centros de saúde. Um total de 125 mulheres>18 anos, voluntárias, foramrecrutadas. A amostra do fórnice vaginal posterior foi obtida por especuloscopia. Foram observadas características da secreção e da genitália externa e interna. A coloração de Gram foi usada para observar a microbiota vaginal, blastoconídios e pseudo-hifas, e a reação em cadeia da polimerase foi usada para a detecção de Trichomonas vaginalis e Candida albicans. O coeficiente kappa de Cohen foi usado na análise de concordância. Resultados De um total de 125 mulheres com AVD, 85,6% consultaram espontaneamente e 14,4% foram diagnosticados clinicamente durante um check-up de rotina. A concordância absoluta foi significativa (p=0,0012), com concordância de 13,6%. A concordância relativa foi significativa, mas razoável para vaginose bacteriana (Kappa =0,21; p=0,003) e candidíase (Kappa=0,22; p=0,001), e leve para tricomoníase (Kappa=0,14; p=0,009). O percentual de coincidência dos diagnósticos (solteiros ou mistos) por laboratório e parteiras foi: vaginose bacteriana 63,2% (12/19), candidíase 36,5% (27/74) e tricomoníase 12,5% (4/32). Houve 20% de coinfecção. Umtotal de 36% dos diagnósticos clínicos de AVD tiveram exames laboratoriais negativos. Conclusão As condições de vulvovaginite candidíase e tricomoníase parecem ser sobrediagnosticadas, e a vaginose bacteriana parece ser subdiagnosticada pelo diagnóstico clínico quando comparado com o diagnóstico laboratorial. A baixa concordância obtida mostra a importância de complementar o diagnóstico clínico comestudo laboratorial de AVD, principalmente emmulheres com falha de tratamento e / ou coinfecções com sinais e sintomas inespecíficos e variáveis.

Abstract Objective To determine the concordance between the clinical diagnosis of women with abnormal vaginal discharge (AVD) and laboratory results using molecular detection and observation of the vaginal microbiota. Methods Cross-sectional study conducted in 2018 in Temuco, Chile. A total of 25 midwives from 12 health centers participated. A total of 125 women>18 years old, volunteers, were recruited. The sample of the posterior vaginal fornix was obtained by speculoscopy. Characteristics of the discharge and of the external and internal genitalia were observed. Gram staining was used to observe vaginal microbiota, blastoconidia and pseudohyphae, and polymerase chain reaction was used for the detection of Trichomonas vaginalis and Candida albicans. The Cohen kappa coefficient was used in the concordance analysis. Results Out of a total of 125 women with AVD, 85.6% consulted spontaneously and 14.4% were diagnosed clinically during a routine check-up. Absolute concordance was significant (p=0.0012), with an agreement of 13.6%. The relative concordance was significant, but fair for bacterial vaginosis (Kappa=0.21; p=0.003) and candidiasis (Kappa=0.22; p=0.001), and slight for trichomoniasis (Kappa=0.14; p=0.009). The percentage of coincidence of the diagnoses (single or mixed) by laboratory and midwives was: bacterial vaginosis 63.2% (12/19), candidiasis 36.5% (27/74), and trichomoniasis 12.5% (4/32). There was 20% coinfection. A total of 36% of the clinical diagnoses of AVD had negative laboratory tests. Conclusion The vulvovaginitis conditions candidiasis and trichomoniasis appear to be overdiagnosed, and bacterial vaginosis appears to be underdiagnosed by the clinical diagnosis when compared with the laboratory diagnosis. The low concordance obtained shows the importance of complementing the clinical diagnosis with a laboratory study of AVD, particularly in women with failed treatments and/or coinfections with unspecific and varying signs and symptoms.

Background: The early onset of sexual activity can promote the development of cervical alterations and sexually transmitted infections, especially the human papillomavirus (HPV) very common in adolescents and young people. Aim: The condition of the cervix, HPV and sexual behavior in young women under 25 years of age were analyzed. Methods: 182 university students, healthy, sexually active, 18-24 years old, without vaccine for HPV participated. Papanicolaou (Pap) test and classification of high and low risk HPV (HR and LR) were performed by real time polymerase chain reaction. The sexual behaviors were consulted in private. Results: The 46.9% of Pap presented cytological alterations, non-specific inflammation/hemorrhagic (29.4%) and atypical smear (10.2%) being de most frequent. The overall frequency of HPV-HR was 24.3%, of these 67.4% presented an altered Pap. There was an association between cytological alterations and HPV (p < 0.0001) and years of sexual activity and atypical smear or cervical intraepithelial neoplasia grade I (CIN I) (p = 0.009). 11.9% of young women (21/177) presented atypical smear or CIN I, with 66.7% of cases HPV-HR. Conclusions: These findings alert the vulnerability of these young women who would have a potential risk of viral persistence, CIN and eventually cancer. It is important to emphasize counseling and prevention prior to the regular age of admission to the screening program for cervical cancer. This study was financed by the Universidad de La Frontera through Projects DI15-0047 and DI17-0123.

Resumen Introducción: El inicio precoz de actividad sexual puede favorecer el desarrollo de alteraciones cervicales y de infecciones de transmisión sexual, en especial del virus papiloma humano (VPH) muy frecuente en adolescentes y jóvenes. Objetivo: Analizar el estado del cuello uterino, presencia del VPH y conductas sexuales en mujeres menores de 25 años. Material y Métodos: Participaron 182 estudiantes universitarias de 18-24 años, sanas, sexualmente activas y no vacunadas para VPH. Se realizó Papanicolaou (Pap) y clasificación del VPH en alto y bajo riesgo (AR y BR) mediante reacción de polimerasa en cadena en tiempo real. Las conductas sexuales fueron consultadas privadamente. Resultados: El 46,9% de los Pap presentaron alteraciones citológicas (inflamación inespecífica/hemorrágico: 29,4% y frotis atípicos (FA):10,2%). La frecuencia de los VPH-AR fue 24,3%; de éstos, 67,4% presentó un Pap alterado. Hubo asociación entre alteraciones citológicas y presencia de VPH (p < 0,0001) y años de actividad sexual y FA o neoplasia intraepitelial grado I (NIE I) (p = 0,009). El 11,9% de las jóvenes estudiadas (21/177) presentó FA o NIE I, con 66,7% de casos VPH-AR. Conclusiones: Estos hallazgos alertan la vulnerabilidad de estas jóvenes que tendrían un riesgo potencial de persistencia viral, NIE y eventualmente cáncer. Es importante enfatizar consejería y prevención previo a la edad normada de ingreso al programa de cribado para cáncer cérvico uterino en Chile.

Mucus is one of the most important components of fish immunity, it contains components of innate immunity such as glycoproteins, lysozyme, complement proteins, proteolytic enzymes, antimicrobial peptides and immunoglobulins. Current information concerning the generation, physiology and effects of mucus in Atlantic salmon is reviewed, as well as possible mucogenic additives for the control of parasites that may be attractive for future use in the reduction of Caligus rogercresseyi. A full-text multidisciplinary data search was carried out. The topics included in the research process correspond to salmon, mucus, and mucogenic additives. It was found that the additive that generates a greater increase of the mucus components is the probiotic Bacillus sp. The findings suggest that more research is needed to unravel the implications of skin mucosal immunity on fish welfare and diseases of biological importance

El mucus es uno de los componentes más importantes de la inmunidad del pescado, contiene componentes de la inmunidad innata como glicoproteínas, lisozima, proteínas del complemento, enzimas proteolíticas, péptidos antimicrobianos e inmunoglobulinas. Se revisa información actualizada concerniente a la generación, fisiología y efectos del mucus en el salmón del Atlántico, así como de posibles aditivos mucogénicos para el control de parásitos que puedan ser atractivos para ser utilizados a futuro en la disminución de Caligus rogercresseyi. En virtud del cometido se realizó una búsqueda de datos multidisciplinarios de texto completo. Los tópicos incluidos en el proceso de investigación corresponden al salmón, al mucus y a los aditivos mucogénicos. Se encontró que el aditivo que genera un mayor aumento de los componentes del mucus es el probiótico Bacillus sp. Los hallazgos sugieren que se necesita más investigación para desentrañar las implicaciones de la inmunidad de la mucosa de la piel sobre el bienestar de los peces y las enfermedades de importancia biológica

Salmon farming is one of the pillars of the Chilean economy but due the emerging of many diseases, including the ecto-parasitism caused by Caligus rogercresseyi, the salmon industry has decreased their production indices. Based on that, alternative rearing systems are being evaluated for salmon cultivation, one of them fish farming in deep water, where the temperature is lower than the temperature of the surface, as C. rogercresseyi is a parasite whose life cycle is water temperature dependent. This paper describes the biological behaviour of the parasite and the effect of deep water and culture temperature on the establishment of the parasite in the host

La salmonicultura constituye uno de los pilares de la economía chilena, pero debido al desarrollo de innumerables enfermedades, entre las que destaca la ectoparasitosis causada por Caligus rogercresseyi, los productores de salmón han disminuido sus índices productivos. Debido a esto, se están buscando sistemas alternos para cultivar salmones, siendo uno de ellos el cultivo de peces en aguas profundas, donde la temperatura es menor que la temperatura de la superficie, ya que C. rogercresseyi es un parásito cuyo ciclo de vida es dependiente de la temperatura del agua. El estudio detalla el comportamiento biológico del parásito y el efecto de la profundidad y temperatura de cultivo sobre el establecimiento del parásito en el hospedero

Background: Human papilloma virus (HPV) and Chlamydia trachomatis are the most prevalent sexually transmitted infections (STIs), among teenagers and young people, with risk factors: active sex life and multiple partners. Chlamydia trachomatis infection may favor HPV infection and this, the development of cervical cancer. Both infections can lead to consequences on sexual and reproductive health. Objective: To determine frequency of HPV and C. trachomatis in asymptomatic university women less than 25 years, associating them with number of sexual partners (n°SxP) and time of sexual activity (TSxA). Material andMethods: 151 cervical samples for HPV and C. trachomatis, were processed by conventional and in real time reaction polymerase chain. Results: HPV 21, 8%, C. trachomatis 11, 2% and co-infection (HPV/C.trachomatis), 4.6%. Aimong HPV +, 80, 6% showed high risk HPV. The n°SxP was strongly associated with HPV. Aimong young coinfected HPV/C. trachomatis, 71.4% had 3 or more PSx. Chlamydia trachomatis was more frequent (64,7%) that HPV within range of 3-5 years according to the TSxA, Discussion: A high prevalence of HPV and C. trachomatis was observed. Young women with coinfection HPV/C. trachomatis could be a high-risk group need to monitor their infections. It suggests the implementation of university programs in education, counseling and prevention in sexual health.

Introducción: El virus papiloma humano (VPH) y Chlamydia trachomatis son las infecciones de transmisión sexual (ITS) más frecuentes, en adolescentes y jóvenes, con factores de riesgo: vida sexual activa y múltiples parejas. Chlamydia trachomatis puede favorecer el ingreso de VPH y éste el desarrollo del cáncer cérvico uterino. Ambas infecciones pueden dejar secuelas en la salud sexual y reproductiva. Objetivo: Determinar frecuencias VPH y C trachomatis en estudiantes universitarias asinto-máticas bajo 25 años, asociándolas con número de parejas sexuales (n°PSx) y tiempo de actividad sexual (TASx). Material y Método: Se procesaron 151 muestras/exo y endo cervicales para VPH y C. trachomatis, mediante reacción de polimerasa en cadena convencional y en tiempo real. Resultados: La frecuencia fue: VPH 21,8%, C. trachomatis 11,2% y co-infección 4,6%. De las jóvenes con infección por VPH, 80,6% presentó VPH alto riesgo oncogénico. El n°PSx se asoció fuertemente a VPH. Entre las jóvenes con co-infección VPH/C. trachomatis, 71,4% tenían tres o más PSx. Según TASx, C. trachomatis fue más frecuente (64,7%) entre 3-5 años que VPH. Conclusión: Se observó alta prevalencia de VPH y C trachomatis. Mujeres jóvenes con co-infección VPH/C. trachomatis podrían ser un grupo de alto riesgo con necesidad de mo-nitorear sus infecciones. Es sugerida la implementación de programas universitarios en educación, orientación y prevención en ITS.

Abstract: Oestrus ovis is a botfly whose larvae cause nasal myiasis, an environmental-dependent disease in small ruminants, generating acute and chronic injuries in the cranial cavities of sheep. Chile is a country of the southernmost worldwide distribution of this parasite, and there is few information about. Whence, the objective of this study was to approximate the epidemiological situation of O. ovis infection in Chilean sheep. From December 2009 to March 2010, a total of 87 samples were obtained by necropsy for skull inspection. The larvae were collected, and microscopically identified. The prevalence in the sampled sheep was 60.9%. From those that were infected, 85.7% (18/21) of sheep were 1 to 3 years old, constituting the stratum with the highest prevalence. The difference of infection in females and males was not significant. The high risk of infection seems to be dependent upon the environmental conditions of this southern region, especially during summer when the first larval stage (L1) could be found as the evidence. Therefore, the disease should be considered as a significant problem for this kind of livestock production.
