METARHIZIUM ANISOPLIAE SENSU LATO NATIVE TO LIVESTOCK SOILS CAUSES HIGH MORTALITY ON RHIPICEPHALUS MICROPLUS LARVAE, ADULTS AND AFFECTS THEIR REPRODUCTION.

The acaricidal effect of 14 strains of Metarhizium anisopliae sensu lato isolated from soil of livestock farms in the Mexican tropics was evaluated against larvae and engorged females, and during the laying and hatching of eggs of Rhipicephalus microplus (Ixodida: Ixodidae). For each fungal strain, the larvae mortality percentage was evaluated through a larval immersion test, while the reproductive efficiency indices in engorged females were measured using adult immersion tests at a dose of 1 × 108 conidia/ml. All strains of M. anisopliae (s.l.) proved to be highly effective against R. microplus larvae (66-100%) and engorged females (100%). The strains also showed a good effect in inhibiting egg laying (16.45-56.38%) and a moderate effect in decreasing egg hatching (5.24-32.68%). Two strains demonstrated to be effective against all development phases of R. microplus in an integrated manner.

Worldwide comparison between the potential distribution of Rhipicephalus microplus (Acari: Ixodidae) under climate change scenarios.

The cattle tick Rhipicephalus microplus (Acari: Ixodidae) has demonstrated its ability to increase its distribution raising spatially its importance as a vector for zoonotic hemotropic pathogens. In this study, a global ecological niche model of R. microplus was built in different scenarios using Representative Concentration Pathway (RCP), Socio-Economic Pathway (SSP), and a climatic dataset to determine where the species could establish itself and thus affect the variability in the presentation of the hemotropic diseases they transmit. America, Africa and Oceania showed a higher probability for the presence of R. microplus in contrast to some countries in Europe and Asia in the ecological niche for the current period (1970-2000), but with the climate change, there was an increase in the ratio between the geographic range preserved between the RCP and SSP scenarios obtaining the greatest gain in the interplay of RCP4.5-SSP245. Our results allow to determine future changes in the distribution of the cattle tick according to the increase in environmental temperature and socio-economic development influenced by human development activities and trends; this work explores the possibility of designing integral maps between the vector and specific diseases.

Analysis of sedentariness in women from a gender and equity perspective.

ABSTRACTThis cross-sectional study aimed to analyse the social and gender-related factors influencing sedentariness in women, including occupation and family size (FS). We included women aged 45-70 years participating in the Breast Cancer Screening Programme of the Valencia Region (BCSP-VR) between November 2018 and October 2019 (n = 121,988). The response variable was sedentariness measured by sitting time in hours/day (h/day) (<3 h/day and ≥3 h/day). The explanatory variables were age, educational level, country of origin, living alone, childcare responsibilities, FS, disability, body mass index (BMI) and smoking status. Logistic regression models were adjusted for the whole sample and were stratified by occupation and FS. The variables that increased the odds of sedentariness were age ≥65 years (OR = 1.28; CI = 1.20-1.36), high educational level (OR = 1.39; CI = 1.31-1.47), non-manual occupation (OR = 2.38; CI = 2.27-2.48), living alone (OR = 1.11; CI = 1.05-1.17), disability (OR = 1.37; CI = 1.20-1.56) and BMI ≥ 30 (OR = 1.33; CI = 1.28-1.38). The variables decreasing the odds were large (OR = 0.90; CI = 0.87-0.96) and medium FS (OR = 0.93; CI = 0.90-0.97). Older age, high educational level and high BMI conferred a higher odd of sedentary lifestyle, independently of occupation and FS with statistical differences. Protective factors were childcare responsibilities in non-working women (OR = 0.86; CI = 0.74-0.99), large FS in women with manual occupations (OR = 0.88; CI = 0.80-0.97) and medium FS in housewives (OR = 0.91; CI = 0.86-0.97). This study identified social and gender-related inequalities in the factors influencing sedentariness, which were related to the type of occupation and FS.Highlights There are social and gender inequalities in the factors influencing sedentarinessNon-manual occupation increases the risk of sedentary lifestyleBelonging to a medium or large family decreases the risk of sedentary behaviourChildcare responsibilities are related to lower sitting time throughout the day.

Acaricidal activity of the hexanic and hydroethanolic extracts of three medicinal plants against southern cattle tick Rhipicephalus (Boophilus) microplus (Acari: Ixodidae).

The southern cattle tick Rhipicephalus microplus is a major problem for the cattle industry in tropical and subtropical areas worldwide. Chemical products are commonly applied to control it; however, their indiscriminate use has resulted in the appearance of resistant lineages. In the last decades, plants have been used as an alternative to conventional acaricidal drugs, as several plant compounds repel activity, decrease the reproductive potential and reduce the survival rate of ticks. For this reason, the in vitro efficacy of hexanic and hydroalcoholic extracts of Randia aculeata, Moringa oleifera and Carica papaya were evaluated against the larvae and engorged females of R. microplus. Larval packet tests and adult immersion tests were performed with seven concentrations of each of the extracts. The extracts obtained with hydroethanolic solution (polar solvent) exhibited a higher acaricidal activity than extracts prepared with n-hexane (non-polar solvent). Hydroethanolic extracts of R. aculeata seed and shell showed the highest larvicidal activity against R. microplus (100 and 91% mortality, respectively) at a concentration of 100 mg/mL. Randia aculeata (seed and shell), M. oleifera and C. papaya treatments at the same concentration (100 mg/mL) also resulted in adult mortality of 85, 75, 66 and 55%, respectively. The adult immersion test showed that hydroethanolic extracts derived from R. aculeata seed significantly reduced the index of egg laying and increased the percentage inhibition of oviposition of female ticks at a concentration of 100 mg/mL. These results indicate that the tested extracts exhibit acaricidal activity and could be considered as potential agents for the development of alternative natural acaricides against R. microplus.

Social mobility and healthy behaviours from a gender perspective in the Spanish multicase-control study (MCC-Spain).

There is evidence for the influence of socioeconomic status (SES) on healthy behaviours but the effect of social mobility (SM) is not yet well known. This study aims to analyse the influence of origin and destination SES (O-SES and D-SES) and SM on healthy behaviours and co-occurrence, from an integrated gender and age perspective. Data were obtained from the controls of MCC-Spain between 2008-2013 (3,606 participants). Healthy behaviours considered: healthy diet, moderate alcohol consumption, non-smoking and physical activity. SM was categorized as stable high, upward, stable medium, downward or stable low. Binary and multinomial logistic regression models were adjusted. Those aged <65, with a low O-SES, D-SES and stable low SM are less likely to have healthy behaviours in the case of both women (physically active: OR = 0.65 CI = 0.45-0.94, OR = 0.71 CI = 0.52-0.98, OR = 0.61 CI = 0.41-0.91) and men (non-smokers: OR = 0.44 CI = 0.26-0.76, OR = 0.54 CI = 0.35-0.83, OR = 0.41 CI 0.24-0.72; physically active: OR = 0.57 CI = 0.35-0.92, OR = 0.64 CI = 0.44-0.95, OR = 0.53 CI = 0.23-0.87). However, for those aged ≥65, this probability is higher in women with a low O-SES and D-SES (non-smoker: OR = 8.09 CI = 4.18-15.67, OR = 4.14 CI = 2.28-7.52; moderate alcohol consumption: OR = 3.00 CI = 1.45-6.24, OR = 2.83 CI = 1.49-5.37) and in men with a stable low SM (physically active: OR = 1.52 CI = 1.02-1.26). In the case of men, the same behaviour pattern is observed in those with a low O-SES as those with upward mobility, with a higher probability of co-occurring behaviours (three-to-four behaviours: OR = 2.00 CI = 1.22-3.29; OR = 3.13 CI = 1.31-7.48). The relationship of O-SES, D-SES and SM with healthy behaviours is complex and differs according to age and gender.

Half metallicity in Cr substituted Fe2TiSn.

Band structure tailoring has been a great avenue to achieve the half-metallic electronic ground state in materials. Applying this approach to the full Heusler alloy Fe2TiSn, Cr is introduced systematically at Ti site that conforms to the chemical formula [Formula: see text]Sn. Compositions so obtained have been investigated for its electronic, magnetic, and electrical transport properties with an aim to observe the half-metallic ferromagnetic ground state, anticipated theoretically for Fe2CrSn. Our experimental study using synchrotron X-ray diffraction reveals that only compositions with [Formula: see text] 0.25 yield phase pure L2[Formula: see text] cubic structures. The non-magnetic ground state of Fe2TiSn gets dramatically affected upon inclusion of Cr giving rise to a localized magnetic moment in the background of Ruderman-Kittel-Kasuya-Yosida (RKKY) correlations. The ferromagnetic interactions begin to dominate for x = 0.25 composition. Results of its resistivity and magnetoresistance (MR) measurement point towards a half-metallic ground state. The calculation of exchange coupling parameter, [Formula: see text], and orbital projected density of states that indicate a change in hybridization between 3d and 5p orbital, support the observations made from the study of local crystal structure made using the extended X-ray absorption fine structure spectroscopy. Our findings here highlight an interesting prospect of finding half-metallicity via band structure tailoring for wide application in spintronics devices.

Combination of phenotype and polygenic risk score in breast cancer risk evaluation in the Spanish population: a case -control study.

BACKGROUND: In recent years, the identification of genetic and phenotypic biomarkers of cancer for prevention, early diagnosis and patient stratification has been a main objective of research in the field. Different multivariable models that use biomarkers have been proposed for the evaluation of individual risk of developing breast cancer. METHODS: This is a case control study based on a population-based cohort. We describe and evaluate a multivariable model that incorporates 92 Single-nucleotide polymorphisms (SNPs) (Supplementary Table S1) and five different phenotypic variables and which was employed in a Spanish population of 642 healthy women and 455 breast cancer patients. RESULTS: Our model allowed us to stratify two groups: high and low risk of developing breast cancer. The 9th decile included 1% of controls vs 9% of cases, with an odds ratio (OR) of 12.9 and a p-value of 3.43E-07. The first decile presented an inverse proportion: 1% of cases and 9% of controls, with an OR of 0.097 and a p-value of 1.86E-08. CONCLUSIONS: These results indicate the capacity of our multivariable model to stratify women according to their risk of developing breast cancer. The major limitation of our analysis is the small cohort size. However, despite the limitations, the results of our analysis provide proof of concept in a poorly studied population, and opens up the possibility of using this method in the routine screening of the Spanish population.

Molecular detection of Rickettsia species in ticks collected in the Mexico-USA transboundary region.

Zoonotic tick-borne diseases, including those caused by Rickettsia species, continue to have serious consequences for public health worldwide. One such disease that has emerged as a major problem in several countries of the American continent is the Rocky Mountain Spotted Fever (RMSF) caused by the bacterium Rickettsia rickettsii. Several tick species are capable of transmitting R. rickettsia, including Amblyomma cajennense, A. aureolatum, A. imitator, Rhipicephalus sanguineus, Dermacentor andersoni, D. variabilis and possibly A. americanum. Despite previous reports in Mexico linking new outbreaks of RMSF to the presence of these tick species, no robust measures have tackled transmission. In the present study, we amplified R. rickettsii from 109 test DNA samples extracted from ticks collected from several animals and humans of Tamaulipas, Mexico, between November 2015 and December 2017. Our analysis revealed the presence of R. rickettsii in six samples and these findings contribute to a spatial distribution map that is intended to minimize the risk of transmission to humans.

Glassy Phonon Heralds a Strain Glass State in a Shape Memory Alloy.

Shape memory strain glasses are frustrated ferroelastic materials with glasslike slow relaxation and nanodomains. It is possible to change a NiCoMnIn Heusler alloy from a martensitically transforming alloy to a nontransforming strain glass by annealing, but minimal differences are evident in the short- or long-range order above the transition temperature-although there is a structural relaxation and a 0.18% lattice expansion in the annealed sample. Using neutron scattering we find glasslike phonon damping in the strain glass but not the transforming alloy at temperatures well above the transition. Damping occurs in the mode with displacements matching the martensitic transformation. With support from first-principles calculations, we argue that the strain glass originates not with transformation strain pinning but with a disruption of the underlying electronic instability when disorder resonance states cross the Fermi level.

Detection of pathogenic Leptospira species associated with phyllostomid bats (Mammalia: Chiroptera) from Veracruz, Mexico.

The genus Leptospira encompass 22 species of spirochaetes, with ten pathogenic species that have been recorded in more than 160 mammals worldwide. In the last two decades, the numbers of records of these agents associated with bats have increased exponentially, particularly in America. Although order Chiroptera represents the second most diverse order of mammals in Mexico, and leptospirosis represents a human and veterinary problem in the country, few studies have been conducted to identify potential wildlife reservoirs. The aim of this study was to detect the presence and diversity of Leptospira sp. in communities of bats in an endemic state of leptospirosis in Mexico. During January to September 2016, 81 bats of ten species from three localities of Veracruz, Mexico, were collected with mist nets. Kidney samples were obtained from all specimens. For the detection of Leptospira sp., we amplified several genes using specific primers. Amplicons of the expected size were submitted to sequencing, and sequences recovered were compared with those of reference deposited in GenBank using the BLAST tool. To identify their phylogenetic position, we realized a reconstruction using maximum-likelihood (ML) method. Twenty-five samples from three bat species (Artibeus lituratus, Choeroniscus godmani and Desmodus rotundus) showed the presence of Leptospira DNA. Sequences recovered were close to Leptospira noguchii, Leptospira weilii and Leptospira interrogans. Our results include the first record of Leptospira in bats from Mexico and exhibit a high diversity of these pathogens circulating in the state. Due to the finding of a large number of positive wild animals, it is necessary to implement a surveillance system in populations of the positive bats as well as in related species, in order to understand their role as carriers of this bacterial genus.

Inhibitory effect of biofilm-forming Lactobacillus kunkeei strains against virulent Pseudomonas aeruginosa in vitro and in honeycomb moth (Galleria mellonella) infection model.

Biofilms correspond to complex communities of microorganisms embedded in an extracellular polymeric matrix. Biofilm lifestyle predominates in Pseudomonas aeruginosa, an opportunistic Gram negative pathogen responsible for a wide spectrum of infections in humans, plants and animals. In this context, anti-biofilm can be considered a key strategy to control P. aeruginosa infections, thereby more research in the field is required. On the other hand, Lactobacillus species have been described as beneficial due to their anti-biofilm properties and their consequent effect against a wide spectrum of pathogens. In fact, biofilm-forming Lactobacilli seem to be more efficient than their planktonic counterpart to antagonise pathogenic bacteria. In this work, we demonstrated that Lactobacillus kunkeei, a novel Lactobacillus species isolated from honeybee guts, can form biofilms in vitro. In addition, the L. kunkeei biofilm can, in turn, inhibit the formation of P. aeruginosa biofilms. Finally, we found that L. kunkeei strains attenuate infection of P. aeruginosa in the Galleria mellonella model, presumably by affecting P. aeruginosa biofilm formation and/or their stability. Since L. kunkeei presents characteristics of a probiotic, this work provides evidence arguing that the use of this Lactobacillus species in both animals (including insects) and humans could contribute to impair P. aeruginosa biofilm formation.

Seroepidemiology of Bovine Herpes Virus-1 Infection in Water Buffaloes from the state of Veracruz, Mexico.

Water buffaloes (Bubalus bubalis) were introduced to Mexico at the end of the last century. In Mexico, buffaloes are commonly pastured together with cattle; however few studies have been done on buffalo herd health in Mexico. We hypothesized that a better knowledge of the epidemiology of infections shared between cattle and buffaloes may improve herd profitability and promote buffalo production in areas unsuitable to cattle farming. This study aimed to determine the prevalence of antibodies against bovine herpes virus - 1 (BoHV1) in water buffaloes raised on six farms from the state of Veracruz, Mexico. Of 368 buffaloes sampled, 217 (59%) were seropositive for BoHV-1. Age was identified as a risk factor for BoHV-1 infection with buffaloes older than 5 years being the most likely to be infected. Animals more than 7 years old had the highest prevalence (86.0%). Females and males had similar seroprevalence rates. Females with history of abortion had higher prevalence of antiBoHV-1 antibodies than those with no record of abortion. Buffaloes and cattle were raised together in only one of the six farms under study. Interaction with cattle was not a risk factor for BoHV-1 seropositivity. This study showed that BoHV-1 is prevalent among buffalo herds in the state of Veracruz, Mexico. Buffaloes appear to play an important role in the epidemiology of BoHV-1 infection in parts of Mexico when there is no apparent risk of interaction with cattle. Animal health programs established to mitigate the burden caused by BoHV-1 must take into consideration buffaloes when this bovid species is part of the agroecosystem shared with cattle.

Presence, characteristics and equity of access to breast cancer screening programmes in 27 European countries in 2010 and 2014. Results from an international survey.

The European Union Council Recommendation of 2 December 2003 on cancer screening suggests the implementation of organised, population-based breast cancer screening programmes based on mammography every other year for women aged 50 to 69years, ensuring equal access to screening, taking into account potential needs for targeting particular socioeconomic groups. A European survey on coverage and participation, and key organisational and policy characteristics of the programmes, targeting years 2010 and 2014, was undertaken in 2014. Overall, 27 countries contributed to this survey, 26 of the 28 European Union member states (92.9%) plus Norway. In 2014, 25 countries reported an ongoing population-based programme, one country reported a pilot programme and another was planning a pilot. In eight countries, the target age range was broader than that proposed by the Council Recommendation, and in three countries the full range was not covered. Fifteen countries reported not reaching some vulnerable populations, such as immigrants, prisoners and people without health insurance, while 22 reported that participation was periodically monitored by socioeconomic variables (e.g. age and territory). Organised, population-based breast cancer screening programmes based on routine mammograms are in place in most EU member states. However, there are still differences in the way screening programmes are implemented, and participation by vulnerable populations should be encouraged.

Preguntas y respuestas sobre resonancia magnética multiparamétrica prostática: todo lo que el urólogo debe conocer / Questions and answers on prostate multiparameter magnetic resonance imaging: Everything a urologist should know

Contexto: Durante muchos años, la detección del carcinoma prostático (CaP) y su manejo terapéutico se basó fundamentalmente en el antígeno prostático específico, el tacto rectal y la biopsia prostática. Sin embargo, estos parámetros poseen conocidas limitaciones. La resonancia magnética multiparamétrica (RMmp) prostática ha tenido en los últimos años un extenso desarrollo, aportando información morfológica y funcional. El objetivo es presentar una revisión actualizada de los alcances y las limitaciones de la RMmp prostática en relación con el CaP, en el marco de una visión multidisciplinaria. Adquisición de evidencia: Se realizó una revisión de la literatura en PubMed, de los artículos referidos a «RMmp/Estadificación/CaP/detección/vigilancia activa/planificación terapéutica/posterapeútica». Se incluyeron 4 revisiones sistemáticas y otros artículos publicados en revistas de alto factor de impacto dentro del área de Radiología y Urología. Síntesis de evidencia: La RMmp aporta información morfológica y funcional respecto al CaP. Esta información está integrada en el modelo de lectura Prostate Imaging Reporting and Data System, clasificándose la probabilidad de carcinoma clínicamente significativo en una escala del 1 al 5. Actualmente está establecida la utilidad de la RMmp en pacientes con antígeno prostático específico elevado y biopsia prostática previa negativa; estadificación tumoral en casos seleccionados; evaluación en los pacientes candidatos a vigilancia activa; planificación de tratamientos focales y evaluación de la persistencia o recurrencia tumoral. Conclusiones: La RMmp actualmente cumple un papel relevante en el diagnóstico y la toma de decisiones terapéuticas del CaP. El uso aún más extendido de la técnica requerirá una valoración coste/beneficio

Context: For many years, the detection of prostate cancer (PC) and the management of its therapy have been based primarily on prostate-specific antigen, rectal examination and prostate biopsy. However, these parameters have known limitations. Multiparametric magnetic resonance imaging (mpMRI) for prostate cancer has undergone extensive development in recent years, providing morphological and functional information. The aim of this study is to present an updated review of the scope and limitations of prostatic mpMRI for PC, in the framework of a multidisciplinary vision. Acquisition of evidence: We conducted a literature review (in PubMed) of articles referencing «mpMRI/staging/ PC/detection/active surveillance/therapy planning/post-therapy». We included 4 systematic reviews and other articles published in high impact-factor journals within the field of radiology and urology. Summary of the evidence: MpMRI provides morphological and functional information concerning PC. This information is integrated into the Prostate Imaging Report and Date System, classifying the probability of clinically significant carcinoma on a scale from 1 to 5. The usefulness of mpMRI is currently being established for patients with high prostate-specific antigen levels and prior negative prostate biopsy; tumour staging in selected cases; assessment of patients who are candidates for active surveillance; the planning of focal treatments; and the assessment of tumour persistence and recurrence. Conclusions: MpMRI currently fills a relevant role in the diagnosis and therapeutic decision-making of PC. More widespread use of the technique requires a cost/benefit analysis

Pelvic MRI findings in relapsed prostate cancer after radical prostatectomy.

PURPOSE/OBJECTIVE: Little is known about the clinical impact of using multiparametric MRI to plan early salvage radiotherapy after radical prostatectomy. We aimed to evaluate the incidence and location of recurrence based on pelvic multiparametric MRI findings and to identify clinical variables predictive of positive imaging results. MATERIALS AND METHODS: We defined radiological criteria of local and lymph node malignancy and reviewed records and MRI studies of 70 patients with PSA recurrence after radical prostatectomy. We performed univariate and multivariate analysis to identify any association between clinical, pathological and treatment-related variables and imaging results. RESULTS: Multiparametric MRI was positive in 33/70 patients. We found local and lymph node recurrence in 27 patients and 7 patients, respectively, with a median PSA value of 0.38 ng/ml. We found no statistically significant differences between patients with positive and negative multiparametric MRI for any variable. Shorter PSADT was associated with positive lymph nodes (median PSADT: 5.12 vs 12.70 months; p: 0.017). CONCLUSIONS: Nearly half the patients had visible disease in multiparametric MRI despite low PSA. Positive lymph nodes incidence should be considered when planning salvage radiotherapy, particularly in patients with a short PSADT.

Instrumentación transuretral en portadores de esfínter urinario artificial. Presentación y discusión de tres casos clínicos / Transurethral instrumentation in patients with artificial urinary sphincter. Presentation and discussion of three clinical cases

El tratamiento para la incontinencia urinaria masculina de esfuerzo severa es la colocación de un esfínter urinario artificial (EUA). La etiología de la incontinencia con frecuencia es la cirugía prostática previa. Los resultados funcionales son buenos con una tasa aceptable de complicaciones. Las complicaciones son más frecuentes si existe radioterapia previa o se realizan procedimientos transuretrales sin tener en cuenta la presencia del manguito del EUA. Cuando es necesaria la cirugía transuretral, por ejemplo por tumor vesical, es necesario realizar el desabrochado del manguito esfinteriano. Los sondajes uretrales precisan también desactivar el manguito y manipular la uretra con sumo cuidado, evitando su manipulación siempre que sea posible. Se presentan tres casos muy complejos de pacientes portadores de EUA que han precisado diversas soluciones ante manipulación uretral y presencia de complicaciones como estenosis de uretra (AU)

Artificial urinary sphincter (AS) is the gold standard treatment for severe male urinary stress incontinence. The etiology of incontinence is often previous prostate surgery as a radical prostatectomy. Functional results are good with an acceptable rate of complications. If there is prior radiotherapy complications are more frequent. When transurethral surgery, for example for bladder tumor is needed, it is necessary unbuttoned the sleeve. Urethral soundings need also turn off the sleeve and manipulate the urethra carefully, avoiding handling whenever possible. We present three very complex cases of patients with US showing several solutions to urethral manipulation and to resolve complications such as urethral perforation and stricture (AU)

Información obligatoria que debe conocer un paciente con cáncer de próstata candidato a vigilancia activa / Obligatory Information that a Patient Diagnosed of Prostate Cancer and Candidate for an Active Surveillance Protocol must know

Objetivos: Conocer la información necesaria para reproducir los resultados de la literatura en vigilancia activa (VA) en cáncer de próstata (CaP) en nuestro propio centro, de tal forma que dicha información sea objetiva y se le pueda dar al paciente de forma fehaciente. Contemplamos estudiar el porcentaje de pacientes candidatos a VA y que la escogen en nuestro ambiente, los datos de infraestadificación, infragradación y predicción de CaP insignificante, depurar el poder predictivo de distintas variables clínicas para mejorar nuestros criterios de selección y analizar los resultados de nuestros pacientes en VA. Material y métodos: Revisión retro y prospectiva de nuestras bases de datos. Se analiza un periodo de un año natural seleccionando posibles candidatos a VA. Análisis de nuestras prostatectomías radicales para conocer las tasas de infraestadificación, infragradación y tasa de CaP insignificante (criterios de Epstein). Análisis uni/multivariado de variables clínicas en pacientes con tumor insignificante en pieza de prostatectomía radical. Valoración prospectiva de supervivencia global y libre de tratamiento activo (SLTA) en pacientes en VA. Resultados: Entre octubre de 2010 y octubre de 2011, un 44,7% de los CaP cumplían criterios para ser incluidos en VA, y un 11,2% la escogieron. Nuestros porcentajes de infraestadificación, infragradación y tasa de CaP insignificante fueron 14%; 31,4%; y 55,7% respectivamente, pero solo 6 pacientes (6,97%) tuvieron CaP ≥ pT3a + Gleason ≥ 7 + volumen > 0,5 cc. En el estudio multivariado para predicción de tumor insignificante, la densidad de PSA y el número de cilindros afectos son factores independientes. Con un seguimiento medio de 36 ± 39 meses, de 232 incluidos en VA, 63 pacientes pasaron a tratamiento activo (27,1%), solo 13 por ansiedad sin progresión patológica. La mediana del tiempo de SLTA es de 72,7 meses (IC 95%: 30,9-114,4). La SLTA a los 24 meses es del 76,4% (69,7-83,1%) y a 48 meses es del 58,1% (48,8-67,4%). Solo 10 pacientes (4,3%) fallecieron, 9 por causa diferente al CaP. La supervivencia global estimada a 5 años es del 92,8% (IC 95%: 86,7-98,9%). Conclusiones: El conocimiento exacto de la casuística de cada centro debería ser obligatorio para informar a los pacientes verazmente de la rentabilidad de la biopsia y de si los porcentajes de infragradación, infraestadificación y de CaP insignificante se adecuan a los de la literatura. A 3 años reproducimos los resultados de las series más longevas de VA, por lo que el programa de VA puede seguir implementándose e incluyendo cada vez a más pacientes

Objectives To know the necessary information to reproduce the results found in the literature on active surveillance (AS) in prostate cancer (PCa) in our own center so that the information would be objective and correctly given to the patients. We have aimed to study the percentage of candidates for AS chosen in our setting, and the data on infrastaging, subgrading and prediction of insignificant PCa, debugging the predictive value of clinical variables to improve our selection criteria and finally to analyze the results of our patients enrolled in AS. Materials and methods: A retro- and prospective review of our data bases was performed. A one-year period was analyzed to know AS candidates. Analysis of our radical prostatectomy specimens for infrastaging, subgrading and prediction of insignificant PCa (Epstein's criteria) was made as well as a uni/multivariate analysis of clinical variables in patients with insignificant PCa in the specimen. A prospective validation was performed with overall survival and survival free of active treatment (SFAT) as endpoints in patients enrolled in AS. Results: Between October-2010/October-2011, 44.7% of our PCa were candidates for AS, but only 11.2% choose it. The percentages found for infrastaging, subgrading and prediction of insignificant PCa were 14%, 31.4% and 55.7%, respectively. However, only just 6 patients (6.97%) had ≥ pT3a + Gleason ≥7 + volume > 0.5 cc PCa. The multivariate analysis showed that PSA density and number of affected cores were independent predictors of insignificant PCa. With a mean follow-up of 36 ± 39 months, 63 out of 232 patients enrolled in AS went on to active treatment (27.1%), with only 13 due to anxiety without pathologic progression. Median time of SFAT was 72.7 months (CI 95% 30.9-114.4). SFAT at 24 months was 76.4% (69.7-83.1%) and at 48 months 58.1% (48.8-67.4%). Only 10 patients died (4.3%), 9 due to causes different of PCa. Estimated overall survival at 5 years was 92.8% (CI 95% 86.7-98.9%). Conclusions: It should be mandatory to have the exact knowledge of the local data of each Center in order to objectively inform patients about prostate biopsy efficiency, and if percentages of infrastaging, subgrading and prediction of insignificant PCa are in accordance with the literature. At 3 years, we reproduced the results of the longest series of AS, so we have ascertained that our AS protocol can be implemented with increasingly more patients
