GnRH antagonist administration to postpone a weekend intrauterine insemination: a large cohort study from a public center.

BACKGROUND: In Spanish public hospital Reproduction Units it is very problematic to perform programmed intrauterine insemination (IUI) on weekends, if indicated. Small previous pilot studies suggest that using a GnRH antagonist to avoid an LH weekend surge would allow to perform IUI on the following Monday, not impairing the expected pregnancy rate. METHODS: Between 1st January 2007 and 31st December 2015, 4.782 intrauterine inseminations were performed at Valladolid University Clinic, Spain, corresponding to 1.650 women. Of them, 911, corresponding to 695 women, should ideally have been performed during the weekend. If it happened that a member of the Reproduction Unit was on duty during that particular weekend, the standard protocol was not interrupted, and the IUI performed as planned (control group, 685 IUIs). If the former was not the case, the weekend gap was bridged by administering 0.25 mg GnRH antagonist (GnRHa). Ovulation was induced by means of 250 ug recombinant HCG (rHCG) 36 h prior to IUI on the following Monday (study group, 226 IUIs). RESULTS: There were no differences in the clinical pregnancy rate (13.7 cc vs. 16.2 %, p = 0.371) or in the ongoing pregnancy rate between groups (11.9 % vs. 14.9 %, p = 0.271). The multiple pregnancy rate was also comparable in both groups (14.7 % vs. 18.5 %, p = 0.77). CONCLUSIONS: Women with a planned IUI which cannot be performed at the ideal date can be offered postponement for two days with the support of GnRHa treatment, with results that are not inferior to those expected applying the regular protocol.

Predictive factors for impaired renal function following nephroureterectomy in upper urinary tract urothelial cell carcinoma.

OBJECTIVES: Despite the uncertain value of adjuvant chemotherapy after radical nephroureterectomy (RNU) it is clear that impaired renal function represents a contraindication to its administration. The objective of this study was to identify possible predictive clinical factors for impaired renal function following RNU in patients with upper urinary tract urothelial cell carcinoma (UUT-UCC). PATIENTS AND METHODS: A retrospective analysis was conducted of 546 patients who underwent RNU between 1992 and 2008 at our institution. Data of interest for this study included estimated glomerular filtration rate (eGFR), age, pathological stage and preoperative hydronephrosis (HN). The predictive value of HN, age and pathological stage for impaired renal function after RNU was calculated by multivariate linear regression analysis. RESULTS: In total, 138 patients met the criteria for inclusion, including 108 men (78%). Mean age at surgery was 67 ± 10 years. There was a significant correlation (p < 0.001) between pre- and postoperative eGFR (decrease of 21% after NU). Preoperative HN was present in 51 patients (37%). On linear regression analysis, preoperative eGFR ≤60 ml/min (p = 0.012; OR = 4.60) and HN (p = 0.027; OR = 10.34) were confirmed to be predictive factors for a postoperative eGFR ≤60 ml/min. When postoperative eGFR ≤45 ml/min was used as the criterion for impaired renal function, predictive factors proved to be preoperative eGFR ≤45 ml/min (p < 0.0001; OR = 18.53), HN (p = 0.038; OR = 0.380) and age ≥70 years (p < 0.0001; OR = 0.169). CONCLUSIONS: Preoperative HN, older age and preoperative eGFR <60 ml/min were proven to be predictive factors for impaired renal function after RNU. In these settings, neoadjuvant chemotherapy may be considered.

Consensus document on the implications of standardization of BCG supply in the management of patients with non-muscle-invasive bladder cancer.

Patients with non-muscle-invasive bladder cancer (NMIBC) in the intermediate and high-risk groups must receive adjuvant treatment with intravesical Bacillus Calmette-Guérin (BCG) following transurethral resection (TUR), as it reduces the risk of recurrence and presumably the risk of progression as well. Optimization of BCG efficacy is achieved by administering maintenance therapy. However, since many immunological aspects of the mechanism of action of BCG in the bladder remain unknown, the implementation of the optimal dose, number of instillations, strains and adequate maintenance regimen over the last decades has been heterogeneous. Additionally, this has hindered the interpretation of efficacy in terms of oncologic outcomes. This, together with the shortages of BCG in recent years, have forced scientific societies to adapt their clinical practice guidelines and modify their protocols of adjuvant treatment with BCG. This includes changes to strains, doses, and maintenance during this period of time. This consensus document evaluates the current status of adjuvant BCG treatment and the implications of BCG supply availability in the treatment of patients with NMIBC. It also addresses the implementation of novel therapies that will improve cancer prognosis and the quality of life of patients with NMIBC in the future.

Changes in the ambulatory care of prostate cancer patients during the SARS-CoV-2 pandemic. Literature review and contribution of our group in telematic care.

INTRODUCTION AND OBJECTIVE: The COVID-19 pandemic has brought about changes in the management of urology patients, especially those with prostate cancer. The aim of this work is to show the changes in the ambulatory care practices by individualized telematic care for each patient profile. MATERIALS AND METHODS: Articles published from March 2020 to January 2021 were reviewed. We selected those that provided the highest levels of evidence regarding risk in different aspects: screening, diagnosis, treatment and follow-up of prostate cancer. RESULTS: We developed a classification system based on priorities, at different stages of the disease (screening, diagnosis, treatment and follow-up) to which the type of care given, in-person or telephone visits, was adapted. We established 4 options, as follows: in priority A or low, care will be given by telephone in all cases; in priority B or intermediate, if patients are considered subsidiary of an in-person visit after telephone consultation, they will be scheduled within 3 months; in priority C or high, patients will be seen in person within a margin from 1 to 3 months and in priority D or very high, patients must always be seen in person within a margin of up to 48 h and considered very preferential. CONCLUSIONS: Telematic care in prostate cancer offers an opportunity to develop new performance and follow-up protocols, which should be thoroughly analyzed in future studies, in order to create a safe environment and guarantee oncologic outcomes for patients.

Current treatments for BCG failure in non-muscle invasive bladder cancer (NMIBC). / Tratamientos actuales tras fracaso a BCG en cáncer de vejiga no músculo-invasivo.

The treatment of choice for high-risk non-muscle invasive bladder cancer (NMIBC) is bacillus Calmette-Guérin (BCG). However, when this fails, the indicated treatment is radical cystectomy. In recent years, trials are being developed with various drugs to avoid this surgery in patients with BCG failure. The aim of this article is to update the treatments under study for bladder preservation in this patient population. Non-systematic review, searching PubMed with the terms "Bladder cancer", "Non-muscle invasive bladder cancer", "NMIBC", "BCG", "BCG-refractory", "Mitomycin C", "MMC", "Hyperthermia", "Electromotive Drug Administration", "EMDA". We used the search engines clinicaltrials.gov and clinicaltrialsregister.eu to find clinical trials. The only intravesical drug approved by the Food and Drug Administration (FDA) for carcinoma in situ (CIS) after failure to BCG is Valrubicin. Recently, the FDA has approved intravenous Pembrolizumab, following the publication of preliminary data from the KEYNOTE-057 study. Atezolizumab has demonstrated similar preliminary efficacy results. Only microwave-induced chemohyperthermia and EMDA-MMC (Electromotive Drug Administration) are recognized as alternatives in European guidelines. Other options under investigation are taxanes and gemcitabine, alone or in combination, recombinant viruses and device-assisted intravesical chemohyperthermia. The results of new drugs are promising, with a large number of trials underway. Knowing the mechanisms of resistance to BCG is essential to explore new therapeutic options.

Recommendations for antibiotic selection for severe nosocomial infections.

Severe infection and its evolution to sepsis are becoming more prevalent every day and are among the leading causes of critical illness and mortality. Proper management is crucial to improve prognosis. This document addresses three essential points that have a significant impact on this objective: a) early recognition of patients with sepsis criteria, b) identification of those patients who suffer from an infection and have a high risk of progressing to sepsis, and c) adequate selection and optimization of the initial antimicrobial treatment.

Androgen deprivation therapy in patients with localized disease: Comparison with curative intent treatments and time to castration resistance. Results of the Spanish Prostate Cancer Registry. / Terapia de privación de andrógenos en pacientes con enfermedad localizada: comparación de las opciones de tratamiento y tiempo hasta la resistencia a la castración. Resultados del Registro Español de Cáncer de Próstata.

BACKGROUND: The effect of primary androgen deprivation therapy (ADT) in patients with localized prostate cancer (PCa) has not been well documented. The objective of the present study was to analyze the outcome of tumors treated with ADT as primary therapy in the Spanish Prostate Cancer Registry (19.4% of the series). PATIENTS AND METHODS: Patients were classified in three groups: 1) with low/intermediate risk clinically localized tumors; 2) with high risk and locally advanced (T3-4) tumors; 3) with metastatic tumors. Time to castration resistance and overall cancer-specific survival were analyzed. In non-metastatic tumors, survivals in patients treated with ADT were compared with data from patients who underwent local treatments from the Spanish Prostate Cancer Registry. RESULTS: 703 cases were analyzed. There were significant differences in the time to castration resistance, which was lower in the group of metastatic tumors. During follow-up, there were 179 deaths (25.5%) of which 89 (12.6%) were due to PCa. After 3 years of ADT, only 14.6% of patients in group 1 had died (1% due to PCa), 20.5% in group 2 and 46.8% in group 3 (9.2% and 31.3% due to PCa, respectively). Cancer-specific survival was significantly worse in group 1 using ADT than radical prostatectomy or radiotherapy. In high-risk and locally advanced tumors, ADT also had a lower cancer-specific survival than local treatments. CONCLUSION: A longer time until the castration resistance was observed in patients with well- and intermediate-risk localized tumors treated with ADT. Patients with metastatic tumors showed the shortest time to castration resistance.

Comparative analysis of the expression of metalloproteases (MMP-2, MMP-9, MMP-11 and MMP-13) and the tissue inhibitor of metalloprotease 3 (TIMP-3) between previous negative biopsies and radical prostatectomies. / Análisis comparativo de la expresión de metaloproteasas (MMP-2, MMP-9, MMP-11 y MMP-13) y del inhibidor tisular de la metaloproteasa 3 (TIMP-3) entre las biopsias previas negativas y las prostatectomías radicales.

Metalloproteases (MMPs) and tissue inhibitor of metalloprotease-3 (TIMP-3) have been associated to the risk of having cancer and tumor aggressiveness. When facing the difficulties of prostate cancer diagnosis, the expression of MMPs and TIMP-3 in negative biopsies could be helpful to evaluate a diagnostic suspicion. Our objective is to carry out a comparative study of the expression of MMPs and TIMP-3 in previous negative biopsies and radical prostatectomies (RP). MATERIAL AND METHODS: Retrospective analysis of a hospital-based cohort including 21 patients with suspicion of prostate carcinoma, whose expressions of MMP-2, 9, 11 and 13 and TIMP-3 were evaluated by immunohistochemistry in the tumor area from previous negative biopsies and RP. RESULTS: Immunohistochemical staining values (Score) for MMPs (-11 and -13) and TIMP-3 showed no significant differences when comparing the areas of negative biopsies where tumors subsequently developed with those of the RP. However, we did observe a significant difference in the increased expression of MMP-2 (P=.002) and MMP-9 (P=.001) in the tumor area of the RP with respect to the corresponding area of the previous negative biopsy. CONCLUSIONS: Our data indicate a higher overall expression of MMP-2 and MMP-9 in the tumor area of the RP compared to the corresponding areas of the negative previous biopsy, which seems to be associated to the process of malignant transformation.

Usefulness of PET/CT 18-FDG for the diagnosis and follow-up of urological, urothelial and kidney tumours. / Utilidad de la PET/TC 18-FDG en diagnóstico y seguimiento de tumores urológicos uroteliales y renales.

INTRODUCTION: New imaging studies have appeared in recent years for the diagnosis and follow-up of metastatic urological tumours. MATERIAL AND METHODS: A total of 41 patients were reviewed with suspected recurrence of a urothelial or kidney tumour, analysing the diagnostic performance of PET-CT scans undertaken between 2013 and 2016. RESULTS: We collected 17 urothelial tumours and 24 renal tumours, with a median follow-up of 30 months. A total of 39.3% of the urothelial tumours were high grade and 29.3% of the kidney tumours were clear cell Fuhrman II. As a whole, the imaging studies detected recurrences in 34 patients. CT was positive in 83% of the patients, while the PET scan was positive in 75.6%, CT/PET coincidence was 50%. The PET scan detected further disease in 41% of the cases compared to 5% by CT. This resulted in a change of therapeutic strategy in 40% of the patients. Sensitivity, specificity, positive predictive value and negative predictive value for the CT and the PET scans were 92% and 92%, 57% and 100%, 92% and 100%, and 57% and 70% respectively. CONCLUSION: The PET scan showed similar sensitivity for urological tumours to the standard imaging techniques but with higher specificity, positive predictive value and negative predictive value. This led to a change in treatment strategy for 40% of the patients in our series. The PET scan will probably become the standard test in the extension and follow-up studies of most urological tumours.

[Clinicopathologic features of renal cell carcinoma incidentally detected through radiological studies]. / Características clínico-patológicas del carcinoma de células renales detectado incidentalmente mediante estudios radiológicos.

OBJECTIVES: To evaluate the reason for diagnosis of renal cell carcinoma and its variation over the years in Radiology 1 and Urology 1 departments of the Asturias Central Universitary Hospital (HUCA) comparing periods 1970-1995 and 1996-2005 and determine whether incidental findings may explain in an independent the prognosis of these tumors or it is dependent on its clinicopathologic characteristics. MATERIAL AND METHODS: We conducted retrospectively, an exhaustive review of medical records of 373 renal cell carcinoma patients that underwent surgical resection during the period 1970-2005, collecting data according to a set protocol. RESULTS: Of the 373 tumors in our series, 146 (39,1%) were diagnosed according to our criteria incidentally, while 227 (60,9%) were diagnosed due to clinical suspicion of a tumor presence. We observed a significant increase in the number of tumors incidentally diagnosed in the second period, when we performed the counting distributing these patients into two groups, firstly those diagnosed between the years 1970-1995 and, secondly, those diagnosed between 1996-2005. We found metastasis, microvascular invasion of surgical piece and treatment of the recurrence as independent factors for specific cancer survival, while nuclear grade, the presence of lymphadenopathies and T3 stage were found as independent factors for recurrence. CONCLUSIONS: Classically renal cell carcinoma was diagnosed when local symptoms were present (hematuria and back pain, were the most common), symptoms associated with metastasis, or the expression of a paraneoplastic syndrome. The discovery of asymptomatic renal cell carcinomas has dramatically increased, since the widespread use of ultrasound and computed tomography (CT) in the study of abdominal pathology. It is worth mentioning that, in our study, although patients diagnosed with incidental tumors had a longer time free to recurrence and survival, however, the presence of clinic was not an independent risk factor for recurrence or cancer-specific survival.

[Therapeutic effect of mitomycin C in the immediate postoperatory in patients with low-risk non-muscle-invasive bladder tumours]. / Efecto terapéutico de mitomicina C en el postoperatorio inmediato de pacientes con tumores vesicales no músculo invasores de bajo riesgo.

INTRODUCTION: Bladder cancer is a disease with a high prevalence due to its recurrence rate. Transurethral resection of the bladder (TURB) is the treatment in initial stages. Nevertheless, a high percentage of non-muscle-invasive tumors treated will have a recurrence 1-2 years afterwards. Adjuvant quemotherapy or immunotherapy after TURB has been administered in order to decrease the rate of recurrence and to prevent progression. PATIENTS AND METHODS: A prospectived, controlled and randomized study was performed. We included 100 patients with non-muscle-invasive and bladder tumors the low grade. All patients had initially a TURB performed and were randomized to either receive or not a single dose mitomycin C (MMC) in the immediate postoperatory. RESULTS: All low grade tumors was less than 3 cm. Mean follow-up was 26.43 +/- 7.65 months. MMC was administered in 49 patients, of these, 67.3% had no recurrence and 32.7% had a non-muscle-invasive recurrence. Of the 51 patients in the non mitomycin, 51% had no recurrence while 47% had a non-muscle-invasive recurrence, and 2% had a muscle-invasive progression. We found significantly differences in time to recurrence among the two groups. SUMMARY: We found a greater time to recurrence in the group of single dose adjuvant MMC being this difference statistically significantly when comparing with the other group.

[Therapeutic effect of mitomycin C in the immediate postoperative period in patients with intermediate-risk non-muscle-invasive bladder tumors]. / Efecto terapéutico de mitomicina C en el postoperatorio inmediato de pacientes con tumores vesicales no músculo invasores de riesgo intermedio.

INTRODUCTION: Approximately 70-85% of transitional bladder cell carcinomas are non-muscle-invasive. After an initial surgery, around 60-90% will have a recurrence, being the highest risk period the first two years. Urothelium instability could be the main reason for recurrence in mid grade tumours, reason why a single dose of a chemotherapy after transurethral resection of the bladder (TURB) might be insufficient. That is why a deferred therapy in occasions associated with maintenance is recommended. PATIENTS AND METHODS: A prospective, controlled and randomized study was performed. We included non-muscle-invasive mid risk bladder tumours. All patients had initially a TURB performed and were randomized to receive a single dose of mitomycin C (MMC), in the immediate postoperative period. RESULTS: A total of 105 patients were included. Mean follow-up was 22, 70 +/- 8, 15 months. MMC was administered to 53 patients. Of these 66, 0% had no recurrence and 34.0% had a non-muscle-invasive recurrence. Of the 52 patients in the non MMC group, 53.8% had no recurrence and 44.2% had a non-muscle-invasive recurrence and only 1 patient had a muscle-invasive progression. We did not find significantly differences in time to recurrence in mid risk tumours when using immediate postoperative single dose of MMC or deferred therapy. There was only one case of myelosuppression. DISCUSSION: In mid risk non-muscle-invasive tumors, some studies suggest that early intravesical instillation of chemotherapy reduces the risk of recurrence after TURB. We could not show significantly differences when comparing postoperatorive MMC versus traditional deferred instillations.

Clinical usefulness of random biopsies in diagnosis and treatment of non-muscle invasive bladder cancer: Systematic review and meta-analysis. / Utilidad clínica de las biopsias aleatorias en el diagnóstico y tratamiento del tumor vesical no-músculo invasivo: revisión sistemática y metaanálisis.

INTRODUCTION AND OBJECTIVE: This systematic review of the literature has been focused on determining the clinical usefulness of random bladder biopsies (RB) in the diagnosis of carcinoma in situ. A meta-analysis was performed to establish the clinic and pathological factors associated to positive biopsies. EVIDENCE ACQUISITION: A systematic review was performed using Pubmed/Medline database according to the PRISMA guidelines. Thirty-seven articles were included, recruiting a total of 12,657 patients, 10,975 were submitted to RB. EVIDENCE SYNTHESIS: The overall incidence of positive RB was 21.91%. Significant differences were found in the incidence of positive RB when patients were stratified according to urine cytology result, tumor multiplicity, tumor appearance, stage and grade. The results of the meta-analysis revealed that the presence of positive cytology, tumor multiplicity, non-papillary appearance tumors, stage T1 and histological grades G2 and G3 represent the risk factors to predict abnormalities in RB. CONCLUSIONS: The incidence of positive RB in patients with non-muscle invasive bladder cancer was 21.91%. The maximum usefulness of RB was observed when these are performed in a standardized way. The results of the meta-analysis showed that besides positive cytology and non-papillary appearance tumors, tumor multiplicity and histological grades G2 and G3 represent risk factors associated to positive RB, suggesting that the use of RB might be extensive to the intermediate risk group of the European Organization for Research and Treatment of Cancer (EORTC).

Review of the evidence on handling drugs and hazardous products in Urology Departments. Consensus document between the Spanish Urological Association and the Spanish Society of Hospital Pharmacy. / Revisión de la evidencia sobre el manejo de medicamentos y productos peligrosos en los servicios de Urología. Documento de consenso entre la Asociación Española de Urología y la Sociedad Española de Farmacia Hospitalaria.

BACKGROUND: The intravesical administration of hazardous drug products is a standard practice in the urology setting, which potentially exposing medical personnel to these drug products. It was deemed necessary to have a consensus document among the scientific societies involved (the Spanish Urological Association and the Spanish Society of Hospital Pharmacy) that collects the best available evidence on the safest handling possible of dangerous drug products in the setting of urology departments. METHODS: We reviewed the legislation and recommendations on the handling of dangerous drug products, both at the national and international level. RESULTS: There is national legislation and regulations for protecting workers who handle dangerous drugs and products, as well as recommendations for handling to protect both the product and workers. DISCUSSION: Following the strategic lines of the European Parliament for 2014-2020 in the chapter on occupational safety and health, the Spanish Urological Association and the Spanish Society of Hospital Pharmacy proposed a series of actions that decrease the risks of exposure for practitioners and caregivers involved in the handling of these products. CONCLUSIONS: After this review, 19 recommendations were established for handling dangerous drug products, which can be summarised as the need to train all individuals involved (from management teams to patients and caregivers), adopt systems that prevent contaminating leaks, implement exposure surveillance programmes and optimise available resources.

[Use of zoledromic acid on pain control in stages M1b of prostate cancer]. / Seguridad del ácido zoledrómico en el control del dolor en el estadio M1b del cáncer de próstata.

OBJECTIVES: To probe the use of Zoledromic acid in the control of the pain due to bone methastasis of a prostate cancer. MATERIAL AND METHOD: We included in our study 37 consecutive patients diagnosed of prostate cancer who developed bone methastasis during 2005 and 2006 to whom we gave a 4 mg dose of Zoledromic acid during a mean time of 10.24 months. RESULTS: We observed a complete control of the pain in 8 of the 20 patients, and partially in 6 of those patients. We did not evaluate any adverse reaction due to this treatment. CONCLUSIONS: We still yet to know whether the administration of this treatment in the early stages of the prostate cancer could prevent or retard the appearance of bone methastasis.

[Radiograph patterns in herpes simples virus I pneumonia in the adult]. / Hallazgos radiológicos de la neumonía por virus herpes simple I en el adulto.

The aim of this study is to describe epidemiology, patogénesis, pulmonary manifestations and Rx findings in adult patients with varicella pneumonia (VP). Four patients were studied. The diagnosis was established by clinical and radiologic criteria. All had fever , esanthem, 3 cough, 2 dyspnea. Chest X-ray showed interstitial micronodular pattern at bases. 1 case developed airspace consolidation by Staphylococcus aureus. 2 were admitted to ICU. The four received IV acyclovir. We concluded that adults patients with VP usually show nodular infiltrates, with favourable course.

Benefit of on nephrectomy for treating metastatic renal cell carcinoma. / Beneficio de la nefrectomía en el tratamiento del carcinoma de células renales metastásico.

INTRODUCTION: Systemic treatment for metastatic renal cell carcinoma (mRCC) has changed with the new therapies, and it is not clear if nephrectomy (NEP) has a survival benefit in this kind of patients. OBJECTIVE: To investigate if NEP associated to systemic treatment improves overall survival (OS) and progression-free survival (PFS). MATERIAL AND METHODS: A retrospective, observational, descriptive study of 45 patients with diagnosis of mRCC between 2006-2014. Advanced cases with only palliative care were excluded, also patients with solitary metastasis who were managed with surgical resection. RESULTS: Finally 34 patients were treated with systemic treatment. Twenty-six also with surgery associated. Seventy percent were intermediate/low risk at the Motzer classification and>80% Karnofsky performance status. PFS was 7m. NEP improves PFS (10 vs. 4m). High risk Motzer decreased PFS (P<.001). The OS was 11.5m. Patients with Karnofsky performance status>80, intermediate or low risk Motzer treated with NEP and mTOR as second line treatment, increased the OS (14 vs. 3m, P=.0001; 14 vs. 6m, P=.001; and 9 vs. 5m, P=.003, respectively). In the multivariate analysis only NEP (P=0,006; HR 4.5) and intermediate/low risk at the Motzer classification(P=.020; HR 8.9) demonstrated significant improvement in OS. CONCLUSIONS: Patients treated with NEP associated to systemic treatment and with an intermediate/low risk in the Motzer classification had a better PFS and OS. The OS also improves in patients treated with mTOR in second line, and Karnofsky performance status>80%in the univariate study, but not in the multivariable one.

The Pinocchio effect and the Cold Stress Test: Lies and thermography.

We applied the use of thermography to cognitive neuropsychology, particularly as an objective marker of subjective experiences, in the context of lying. We conducted three experiments: (a) An important lie was invented by the participants in 3 min, and it was recounted by phone to a significant person while they were recorded by the thermographic camera, obtaining a face and hands map of the lie. (b) A similar methodology was carried out, but adding the Cold Stress Test (CST) of the dominant hand during the phone call, obtaining a second physiologic marker (the percentage of thermal recovery) to detect the lie. Further, it established a control condition where it generated anxiety in the participants using IAPS images with negative valence and high arousal, which were described by phone to a loved one. We obtained results that showed significant correlations between changes in body temperature and mental set. Of particular interest was the temperature of the nose and hand, which tended to decrease during lying (Experiment 1). The participants also showed a lower recovery of the temperature after the CST when they were lying (Experiment 2). (c) Experiment 3 is a replication of Experiment 2 but with a different type of lie (a more ecological task) in a different scenario (following the ACID interview, with the use of the phone eliminated and participants motivated to lie well). The main pattern of results was replicated. We obtained an accuracy of 85% in detection of deception with 25% of false alarms.

Metalloproteinase 11, potential marker and molecular target in advanced and castration-resistant prostate cancer. Culture study of peritumoral fibroblasts. / Metaloproteinasa 11, potencial marcador y diana molecular en cáncer de próstata avanzado y resistente a la castración. Estudio en cultivo de fibroblastos peritumorales.

OBJECTIVE: To analyze the expression of metalloprotein 11 (MMP11) in cultured fibroblasts obtained from human prostate tumors with different clinical and pathological characteristics. MATERIAL AND METHODS: For this study we analyzed samples of transrectal prostate biopsies from tumors with different characteristics, treated with or whithout androgen deprivation (AD). After optimization of the culture method, fibroblasts were isolated and cultured to perform the study (PCR) of MMP11 mRNA. RESULTS: Finally, 37 cases were studied: 5 samples of benign prostatic hyperplasia, 14 cases with localized neoplasms (7 high-risk according to the D'Amico classification), 5 with metastasic tumors (bone metastases), and 13 treated with AD therapy, of which 6 fulfilled the requirements to be defined as resistant to castration. In tumors without AD therapy, MMP11 expression was significantly higher (P=.001) in fibroblasts of higher grade tumors. A significant (P=.001) correlation was found between PSA and expression of MMP11 in fibroblast s and a significant increase of MMP11 expression in metastatic tumors. In tumors with AD therapy, a significantly greater expression of MMP11 was observed in resistant to castration patients than in those sensitive to castration (P=.003). CONCLUSION: In advanced prostate tumors or in stages of increased tumor aggressiveness, the production of MMP11 by fibroblasts is significantly greater than in non-metastatic tumors or in AD sensitive tumors.
