Efectividad del tratamiento del cáncer de próstata en la Provincia de Villa Clara

A retrospective analytical study was conducted to determine the differences in prostate cancer treatment with radiotherapy and radiotherapy plus hormone therapy in the province of Villa Clara from January 2000 to December 2006. The universe consisted of 70 patients diagnosed with prostate cancer who were treated at the Radiotherapy Service of the Celestino Hernandez Robau Provincial Hospital in this period. After the implementation of the authorial criteria, the data were obtained from the medical records.  the patients were studied and it was determined what type of treatment would be used according to the proposed modalities: a monotherapy with radiotherapy, radiation therapy combined with hormone therapy and radiation therapy combined with androgenic block. The complications of such treatments were determined: the most common are the immediate ones, secondary to radiation therapy, mainly radiation dermatitis, cystitis, and urinary frequency. Five-year survival was better when both treatments were combined, and biochemical progression was less in that therapeutic modality. It is recommend an orchiectomy, and radiation therapy associated with oral estrogen.Se realizó un estudio analítico y retrospectivo para determinar las diferencias del tratamiento del cáncer de próstata con radioterapia y radioterapia más hormonoterapia en la Provincia de Villa Clara desde enero de 2000 hasta diciembre de 2006. El universo de estudio estuvo integrado por 70  pacientes con diagnóstico de cáncer de próstata que recibieron tratamiento en el Servicio de Radioterapia del Hospital Provincial “Celestino Hernández Robau” en este período. Después de la aplicación de criterios autorales se obtuvieron los datos de las historias clínicas, se procedió a estudiar dichos pacientes y se determinó qué tipo de tratamiento se emplearía de acuerdo a las modalidades propuestas: radioterapia monoterápica, radioterapia combinada con hormonoterapia y radioterapia combinada con bloqueo androgénico. Se determinaron las complicaciones de dichos tratamientos: las más frecuentes son las inmediatas, secundarias a la radioterapia, fundamentalmente la radiodermitis, la cistitis, y la polaquiuria. La supervivencia en cinco años fue mejor cuando se combinaron ambas terapéuticas y la progresión bioquímica fue menor en esa misma modalidad terapéutica; se recomienda utilizar la orquiectomía, estrógenos orales asociados con radioterapia

Production of spinach in intensive Mediterranean horticultural systems can be sustained by organic-based fertilizers without yield penalties and withlow environmental impacts

Agricultural production of leafy vegetables in Mediterranean countries aims to achieve high yields without elevated nitrate contents in the edible parts. This implies an adjusted nutrient management, especially of nitrogen (N), in irrigated horticultural systems under semiarid conditions. These horticultural systems are highly relevant in SE Spain from an economic perspective. However, the management of N fertilizer, generally applied in large amounts (150–250 kg N ha−1 in a split application), could trigger losses of reactive N to the environment. The use of novel fertilizers may fulfill the nitrogen requirements of the crop, but should also help to decrease the environmental impacts of production, thus achieving carbon-neutral horticultural systems through (e.g.) enhancement of carbon (C) stocks and greenhouse gases (GHG) emission abatement. In this experiment, eight different fertilizing scenarios at a normalized N application rate of 150 kg N ha−1 were assessed in terms of crop yields, nutrients uptake, C stocking capacity, and yield-scaled GHG emissions. Inorganic NPK fertilizers, digestates, biosolids, composts, and vermicomposts were included among this set of fertilizers. Our results show that organic-based stabilized materials, especially composts, lowered the NO3 − concentration in spinach leaves, in comparison to organic raw materials and synthetic fertilizers. They also produced yields similar to those of slow-release synthetic fertilizers, but with a significant increase in soil organic C 61 days after application. In general, N2O emissions were positively affected by the treatments. Nevertheless, direct N2O emissions were generally low (the highest emission factor, 0.13, being for the biosolid treatment) due to the combined mitigating effect of both the edapho-climatic conditions and the management practices. In general, cumulative CO2 emissions were high in all organic scenarios compared to the control treatment (299 kg C-CO2 ha−1), the highest values being observed in the treatment with biosolid (589 kg C-CO2 ha−1), probably due to differences in the labile organic C contents. In conclusion, some of the organic-based treatments showed multiple positive effects: on crop quality (i.e. leaf N content), crop yields, and GHG mitigation potential. Based on our results, the use of these materials represents an optimized N fertilizer strategy to help achieve a circular economy, by closing nutrient loops and decreasing the environmental impacts of horticultural production systems in semiarid regions of southern Europ

Cannonball jellyfish digestion: an insight into the lipolytic enzymes of the digestive system

The digestive system and metabolism of the cannonball jellyfish Stomolophus sp. 2 are not well-known. The digestion study was critical to explain its ecology and bloom success. Different enzymes are involved in food digestion, which hydrolyze carbohydrates, proteins, and lipids. This study detected lipolytic activity in enzymatic extracts from gastric pouches of Stomolophus sp. 2 collected in the summer of 2013 at Bahía de Kino, Sonora, México (28°47′47″N 111°57′25″W). Lipase/esterase activity showed optimal pH at 11.0 and 50–60 °C with a half-life (t1/2) of 33 min at 55 °C, whereas halotolerance of this activity was recorded from 0-4 M NaCl. Metal ions Ca2+ and Mn2+ did not affect the activity, but Mg2+ decreased it 14.2% ± 3.15, while chelating agents as ethylenediaminetetraacetic acid reduced the activity 8.55% ± 2.13. Inhibition of lipase/esterase activity with tetrahydrolipstatin and paraoxon-ethyl decreased the activity 18.2% ± 2.3, and 62.80% ± 0.74, respectively, whereas phenylmethanesulfonyl fluoride (a protease inhibitor) did not affect it. The enzyme displayed a higher specificity for short-chain triglycerides, but triolein, coconut oil, olive oil, and fish oil were hydrolyzed. For the first time, phospholipase activity from the gastric pouch of Stomolophus sp. 2 was detected using L-α-phosphatidylethanolamine from chicken egg yolk as a substrate. These results suggest that Stomolophus sp. 2 hydrolyze several kinds of lipids, and lipolytic enzymes are active at alkaline pH under different saline conditions, which may be essential to digest different preys

Clinical and pathological characteristics of peripheral T‐cell lymphomas in a Spanish population: a retrospective study

We investigated the clinicopathological features and prognostic factors of patients with peripheral T-cell lymphoma (PTCL) in 13 sites across Spain. Relevant clinical antecedents, CD30 expression and staining pattern, prognostic indices using the International Prognostic Index and the Intergruppo Italiano Linfomi system, treatments, and clinical outcomes were examined. A sizeable proportion of 175 patients had a history of immune-related disorders (autoimmune 16%, viral infections 17%, chemo/radiotherapy-treated carcinomas 19%). The median progression-free survival (PFS) and overall survival (OS) were 7·9 and 15·8 months, respectively. Prognostic indices influenced PFS and OS, with a higher number of adverse factors resulting in shorter survival (P 15% of cells were positive in anaplastic lymphoma kinase-positive and -negative anaplastic large-cell lymphoma and extranodal natural killer PTCL groups. We observed PTCL distribution across subtypes based on haematopathological re-evaluation. Poor prognosis, effect of specific prognostic indices, relevance of histopathological sub-classification, and response level to first-line treatment on outcomes were confirmed. Immune disorders amongst patients require further examination involving genetic studies and identification of associated immunosuppressive factors
