Evaluación de la teleconsulta en el paciente urológico durante la pandemia COVID-19 / Evaluation of teleconsultation system in the urological patient during the COVID-19 pandemic

INTRODUCCIÓN: La pandemia global de COVID-19 ha provocado una rápida implantación de la telemedicina, pero existe escasa información sobre la satisfacción percibida por el paciente como alternativa a la asistencia presencial. OBJETIVO: Se evalúa la satisfacción del paciente urológico con la teleconsulta durante la pandemia COVID-19. MATERIAL Y MÉTODOS: Estudio observacional, prospectivo transversal, no intervencionista, mediante encuesta telefónica durante el periodo considerado pico de pandemia (marzo-abril 2020). Se realiza una encuesta de calidad compuesta por 11 preguntas sobre la atención urológica durante la pandemia COVID-19 por los facultativos, seleccionando una muestra representativa de los pacientes atendidos en el periodo por teleconsulta. RESULTADOS: Doscientos pacientes fueron contactados telefónicamente para responder a una encuesta de calidad sobre teleconsulta. La distribución de pacientes encuestados entre las consultas monográficas fue homogénea entre el número de consultas citadas en el periodo, requiriendo el 18% de ellos ayuda por familiar. El 60% de los pacientes evitaron acudir a un centro médico durante la pandemia. El 42% de los pacientes encuestados tenían cancelada alguna prueba complementaria, el 59% alguna consulta médica, el 3,5% tratamientos y el 1% intervenciones. El 10% apreciaron un empeoramiento de su sintomatología urológica durante el confinamiento. La resolución subjetiva de la consulta por el facultativo fue alcanzada en el 72% de los casos, siendo la teleconsulta por el urólogo habitual en el 81%. El grado de satisfacción global con la teleconsulta fue de 9 (RIQ 8-10), considerando la teleconsulta como una «opción de asistencia sanitaria» pasada la crisis sanitaria por el 61,5% de los encuestados. CONCLUSIÓN: La teleconsulta ha sido valorada con un alto grado de satisfacción durante la pandemia COVID-19, ofreciendo asistencia continuada a los pacientes urológicos durante la crisis sanitaria. La calidad percibida ofrece un campo de asistencia telemática opcional en pacientes seleccionados, que debe reevaluarse fuera de una situación de confinamiento

INTRODUCTION: The global pandemic of COVID-19 has led to rapid implementation of telemedicine, but there is little information on patient satisfaction of this system as an alternative to face-to-face care. OBJECTIVE: To evaluate urological patient satisfaction with teleconsultation during the COVID-19 pandemic. MATERIAL AND METHODS: Observational, prospective, cross-sectional, non-interventional study carried out by telephone survey during the period considered as the peak of the pandemic (March-April 2020). A quality survey composed of 11 questions on urological care provided by physicians during the COVID-19 pandemic was conducted, selecting a representative sample of patients attended by teleconsultation. RESULTS: Two hundred patients were contacted by telephone to answer a survey on the quality of teleconsultation. The distribution of patients surveyed among the specialized consultations was homogeneous with the number of consultations cited in the period; 18% of them required assistance from family members. Sixty percent of patients avoided going to a medical center during the pandemic. Of the surveyed patients, 42% had cancelled diagnostic tests, 59% had cancelled medical consultations, 3.5% had cancelled treatments and 1% had cancelled interventions. Ten percent reported a worsening of urological symptoms during confinement. According to physicians, consultations were effectively delivered in 72% of cases, with teleconsultation being carried out by their usual urologist in 81%. Teleconsultation overall satisfaction level was 9 (IQI8-10), and 61.5% of respondents consider teleconsultation as a «health care option» after the healthcare crisis. CONCLUSION: Teleconsultation has been evaluated with a high level of satisfaction during the COVID-19 pandemic, offering continuous care to urological patients during the healthcare crisis. The perceived quality offers a field of optional telematic assistance in selected patients, which should be re-evaluated in a period without confinement measures

Experiencia inicial del uso de SelectMDx(R) en el diagnóstico de cáncer de próstata en un entorno de práctica clínica habitual «real-world evidence» / Initial experience with SelectMDx(R) in the diagnosis of prostate cancer in a real-world evidence clinical practice setting

INTRODUCCIÓN: El uso de biomarcadores en la detección del cáncer de próstata (CP) puede disminuir el sobrediagnóstico y sobretratamiento de CP no significativos. Analizamos la utilidad y aplicabilidad del marcador SelectMDx® en un entorno de práctica clínica habitual. MATERIAL Y MÉTODOS: Estudio retrospectivo de 48 pacientes evaluados mediante el test SelectMDx® entre julio de 2017 y abril de 2019. Los pacientes se estratificaron en dos grupos según el riesgo estimado por el test de CP clínicamente significativo (CP-CS): < 2% o «muy bajo riesgo», y > 2%. Los resultados se expresaron en función de los antecedentes de biopsia prostática (BP) y resonancia magnética multiparamétrica (RMmp). RESULTADOS: En pacientes con BP negativa y RMmp normal/dudosa el riesgo fue < 2% en 7/9 casos. En pacientes sin BP y RMmp normal/dudosa el riesgo fue < 2% en 12/18 casos, y 2/6 casos con un riesgo % presentaron un CP-CS. De los 14 pacientes sin BP ni RMmp previas, 9 presentaron un riesgo < 2%, con 2 casos diagnosticados de CP en los 5 pacientes con riesgo > 2%. En el resto de subgrupos el número de pacientes es pequeño como para poder extraer conclusiones. En todos los casos con tacto rectal patológico el test demostraba un riesgo de padecer CP > 2%. CONCLUSIÓN: SelectMDx® es un test prometedor para detectar pacientes con un riesgo muy bajo de CP-CS, especialmente en pacientes con sospecha de CP con o sin BP negativas, en los que la RMmp muestre un resultado normal/dudoso. La presencia de un tacto rectal patológico puede condicionar el resultado del test

INTRODUCTION: The use of biomarkers in the detection of prostate cancer (PC) can decrease overdiagnosis and overtreatment of non-significant PC. We analyze the usefulness and applicability of the SelectMDx® marker in a routine clinical practice setting. MATERIAL AND METHODS: Retrospective study of 48 patients evaluated by the SelectMDx® test between July 2017 and April 2019. Patients were stratified into two groups according to the risk estimated by the clinically significant CP test (CS-PC): < 2% or 'very low risk', and > 2%. Results were expressed based on previous prostate biopsy (PB) and multi-parametric magnetic resonance imaging (mpMRI) outcomes. RESULTS: Patients with negative PB and normal/doubtful mpMRI had < 2% risk in 7/9 cases. Patients without PB and normal/doubtful mpMRI had < 2% risk in 12/18 cases, and 2/6 cases with a > 2% risk presented CS-PC. Of the 14 patients with no previous PB or mpMRI, 9 had < 2% risk, and 2 cases were diagnosed with PC from the group of patients (5) with risk >2%. The number of patients in the remaining subgroups is too small to draw any conclusions. In all cases with pathological digital rectal examination, the test showed a > 2% PC risk. CONCLUSION: SelectMDx® is a promising test for detecting patients with a very low risk of CS-PC, especially in patients with suspected PC, with or without negative PB, with normal/doubtful mpMRI. The presence of a pathological digital rectal examination may condition the result of the test

Casos complejos. Enfermedad de Peyronie: cirugía sin/con implante de prótesis de pene / Complex Peyronie's disease cases: surgery with or without penile prosthesis placement

INTRODUCCIÓN Y OBJETIVO: El tratamiento de elección en pacientes con enfermedad de Peyronie con dificultad para la penetración o disfunción eréctil sin adecuada respuesta a fármacos es la cirugía. Se han descrito múltiples técnicas, y cada una de ellas acarrea posibles complicaciones y secuelas que el urólogo debe conocer para ofrecer al paciente la mejor alternativa posible. PACIENTES Y MÉTODOS: Se exponen 3 casos complejos de pacientes con enfermedad de Peyronie. El primero de ellos es un paciente con una secuela tras una plicatura peneana por una curva importante dorsal. El segundo es un paciente con dificultad para la penetración anal secundaria a un problema de dirección de la erección tras una cirugía de incisión de placa con injerto de mucosa oral. El último caso es un paciente con una complicación tardía en el postoperatorio de una colocación de prótesis de 3 componentes con incisión de la placa y parche de colágeno equino. RESULTADOS: Se detallan y discuten las posibles opciones quirúrgicas para los 3 pacientes. Los pacientes fueron informados de las diferentes opciones y se decidió de manera consensuada la cirugía definitiva. CONCLUSIONES: La cirugía de la enfermedad de Peyronie exige al urólogo la consideración de las esferas funcional, estética y psicológica a la hora de plantear alternativas de tratamiento. Un abordaje sistemático de todas ellas evita complicaciones y secuelas, y mejora los resultados

INTRODUCTION AND OBJECTIVE: Surgery is the treatment of choice for patients with Peyronie's disease presenting difficulty in penetration or erectile dysfunction without adequate response to therapy. Several techniques have been described, and urologists must be aware of their possible complications and sequelae in order to offer the patient the best possible alternative. PATIENTS AND METHODS: Three complex cases of patients with Peyronie's disease are presented. The first case exposes a complication after penile plication for the treatment of a major dorsal curve. The second case refers to difficult anal penetration secondary to a problem of erection direction after plaque incision surgery with oral mucosa grafting. The last case is a patient with a late post-operative complication of a three-piece prosthesis placement with plaque incision and equine collagen patch. RESULTS: Surgical options for each case are detailed and discussed. After patients were informed, the decision was taken in a consensual manner

Hydrothermal thresholds for seed germination in winter annual forbs from old-field Mediterranean landscapes.

Under Mediterranean climates with dry-hot summers and cool-wet winters, many forbs with potential for habitat restoration are winter annuals, but there is little information about their germination. We performed laboratory germination experiments on 13 ruderal dicots native to Andalusia (southern Spain). We measured the germination of recently harvested seeds from natural populations across nine temperature treatments (from 5 to 35 °C, constant and alternate); two storage periods; and eight water stress treatments (from 0 to -1.0 MPa). We then calculated the hydrothermal thresholds for seed germination. Final germination ranged from 0-100% and results were mixed in response to temperature. Base temperature was below 6 °C, optimal temperature was around 14 °C and the ceiling temperature around 23 °C. For five species, 10 months of storage improved total germination, indicating a dormancy-breaking effect, but the other species did not respond or had their germination reduced. All species were relatively tolerant to water stress, with base water potential ranging from -0.8 to -1.8 MPa. Our results suggest that hydrothermal germination thresholds, rather than physiological dormancy, are the main drivers of germination phenology in annual forbs from Mediterranean semi-dry environments. The variation in germination responses of these forb species differs from winter annual grasses, but their seeds are all suitable for being stored before restoration.

Seed ecology of the geophyte Conopodium majus (Apiaceae), indicator species of ancient woodland understories and oligotrophic meadows.

Conopodium majus is a geophyte with pseudomonocotyly, distributed in Atlantic Europe. It is an indicator of two declining European habitats: ancient woodland understories and oligotrophic hay meadows. Attempts to reintroduce it by seed have been hindered by scarce seedling emergence and limited knowledge of its seed biology. Micro-CT scanning was used to assess pseudomonocotyly. Embryo growth and germination were studied in the laboratory and the field, using dissection and image analysis. The effects of temperature, light, nitrate and GA3 on germination were tested. Seed desiccation tolerance was investigated by storage at different RHs and by drying seeds at different stages of embryo growth. Seeds possess morphological but not physiological dormancy. Embryo growth and germination were promoted by temperatures between 0 and 5 °C, arrested above 10 °C, and indifferent to alternating temperatures, light, nitrate and GA3 . Pseudomonocotyly appears to result from cotyledon fusion. While seeds tolerated drying to 15% RH and storage for 1 year at 20 °C, viability was lost when storage was at 60% RH. Seeds imbibed at 5 °C for 84 days had significant internal embryo growth but were still able to tolerate drying to 15% RH. Reproduction by seed in C. majus follows a strategy shared by geophytes adapted to deciduous temperate forests. The evolution of fused cotyledons may enable the radicle and the hypocotyl to reach deeper into the soil where a tuber can develop. The embryo is capable of growth within the seed at low temperatures so that germination is timed for early spring.

Comparative seed germination traits in alpine and subalpine grasslands: higher elevations are associated with warmer germination temperatures.

Seed germination traits in alpine grasslands are poorly understood, despite the sensitivity of these communities to climate change. We hypothesise that germination traits predict species occurrence along the alpine-subalpine elevation gradient. Phylogenetic comparative analyses were performed using fresh seeds of 22 species from alpine and subalpine grasslands (1600-2400 m) of the Cantabrian Mountains, Spain (43° N, 5° W). Laboratory experiments were conducted to characterise germinability, optimum germination temperature and effect of cold and warm stratification on dormancy breaking. Variability in these traits was reduced by phylogenetic principal component analysis (phyl.PCA). Phylogenetic generalised least squares regression (PGLS) was used to fit a model in which species average elevation was predicted from their position on the PCA axes. Most subalpine species germinated in snow-like conditions, whereas most alpine species needed accumulation of warm temperatures. Phylogenetic signal was low. PCA1 ordered species according to overall germinability, whilst PCA2 ordered them according to preference for warm or cold germination. PCA2 significantly predicted species occurrence in the alpine-subalpine gradient, as higher elevation species tended to have warmer germination preferences. Our results show that germination traits in high-mountain grasslands are closely linked to the alpine-subalpine gradient. Alpine species, especially those from stripped and wind-edge communities, prefer warmer germination niches, suggesting that summer emergence prevents frost damage during seedling establishment. In contrast, alpine snowfield and subalpine grassland plants have cold germination niches, indicating that winter emergence may occur under snow to avoid drought stress.
