Abstract
Pulmonary arterial hypertension (PAH) requires structured processes of diagnosis and risk stratification, being the function of the right ventricle (RV) a hallmark prognosis determinant. The main therapeutic goals in PAH are to improve and try to revert RV dysfunction and maintaining a low risk. Currently, there are multiple treatments with different mechanisms of action, the combination of which in double or triple therapy has shown improved results compared to monotherapy. Recent clinical evidence shows the importance of early incorporation of parenteral prostanoids to the scheme, improving RV function and survival. In this review, we discuss the role of the RV function in the diagnosis, prognosis, and follow-up of PAH. We recommend the systematic and standardised evaluation of the RV as well as the early initiation of combined treatment in cases of intermediatehigh risk to try to reach and keep the patient with PAH at a low risk and / or avoid the progression of PAH.

Abstract
OBJECTIVE To conduct a cross-cultural adaptation of the Cambridge Pulmonary Hypertension Outcome Review (CAMPHOR) as an instrument to evaluate the perception of symptoms, functional limitation, and health-related quality of life (HRQoL) in subjects diagnosed with pulmonary arterial hypertension (PAH) or chronic thromboembolic pulmonary hypertension (CTEPH) in Colombia. METHODS The adaptation process involved 3 phases: translation, cognitive debriefing interviews, and a validation survey. To evaluate the psychometric properties, we recruited individuals ≥ 18 years of age who had been diagnosed with PAH or CTEPH to take part in the latter two stages of the adaptation process. All individuals were being followed on an outpatient basis by the pulmonary hypertension programs at Hospital Universitario San Ignacio, Fundación Clínica Shaio,and Clínicos IPS, all located in the city of Bogotá, Colombia. RESULTS A Spanish-language version of the CAMPHOR was developed for use in Colombia. The internal consistency was excellent for the symptoms, functioning, and quality of life scales (Cronbach's alpha coefficients of 0.92, 0.87, and 0.93, respectively). Test-retest reliability was above 0.70. The evaluation of the convergent validity and known group validity of the CAMPHOR scales confirmed that there were moderate and strong correlations with the related constructs of the Medical Outcomes Study 36-item Short-Form Health Survey, version 2, as well as showing their capacity to discriminate disease severity. CONCLUSIONS The Spanish-language version of the CAMPHOR developed for use in Colombia was the result of a translation and cultural adaptation process that allows us to consider it equivalent to the original version, having shown good psychometric properties in the study sample. Therefore, its use to assess the impact of interventions on the HRQoL of patients with PAH or CTEPH is recommended, in research and clinical practice.

Abstract
Ammonia-treated bagasse with 80%(w/w) moisture content was subjected to mixed-culture solid-substrate fermentation (SSF) with Trichoderma reesei LM-UC4 and Aspergillus phoenicis QM 329, in flask or pot fermenters, for cellulase production. Significantly higher activities of all the enzymes of the cellulase complex were achieved in 4 days of mixed-culture SSF than in single-culture (T. reesei) SSF. The highest filter-paper-cellulase and β-glucosidase activities seen in mixed-culture SSF were 18.7 and 38.6 IU/g dry wt, respectively, representing approx. 3- and 6-fold increases over the activities attained in single-culture SSF. The mixed-culture SSF process also converted about 46% of the cellulose and hemicellulose to reducing sugars and enriched the product with 13% fungal protein. The biomass productivity, 0.29 gl(-1).h, and enzyme productivity, 28.0 IU I(-1).h, were about twice as high in the mixed-culture than in the single-culture.

Abstract
INTRODUCTION HER-2 has been associated with castrate resistant prostate cancer and matrix metalloproteinase-2 (MMP-2) in the dissemination and invasion of tumor cells as well as activating angiogenesis. We present an immunocytochemical study of the effect of androgen blockade on the expression of HER-2 and MMP-2 in bone marrow micrometastasis and the surrounding stromal cells in men with prostate cancer. METHODS AND PATIENTS A cross-sectional study of men with prostate cancer. Touch preps were obtained from bone marrow biopsies of men with prostate cancer, before and after radical prostatectomy and during androgen blockade. Micrometastasis detected with anti-PSA immunocytochemistry underwent processing with anti-HER-2 and anti-MMP-2 immunocytochemistry. Patients were defined as HER-2 positive or negative, MMP-2 negative or an MMP-2 pattern described as border or central and stromal MMP-2 defined as positive or negative. The expression of the biomarkers was compared before and after primary treatment and during androgen blockade in relation to the serum PSA at the time of sampling and duration of androgen blockade. RESULTS 191 men participated, 35 men before surgery and 43 after surgery; there were no significant differences in HER-2 expression between groups, there was no MMP-2 expression centrally or stromal expression of MMP-2. In men with androgen blockade, HER-2 expression was significantly higher; there was a trend for increasing HER-2 expression up to 5 years; central MMP-2 expression significantly increased after 3 years, while stromal MMP-2 significantly increased after 6 years. MMP-2 expression both in micrometastasis and stroma was significantly associated with HER-2 expression. Expression of MMP-2 at the border of the micrometastasis was not associated with HER-2 expression and occurred in the absence of androgen blockade. CONCLUSIONS Androgen blockade decreases serum PSA by eliminating HER-2 negative prostate cancer cells. However, there is early selection of HER-2 positive cancer cells which leads to androgen independence and to increased expression of MMP-2 activity in the micrometastasis. The increased MMP-2 activity in the micrometastasis increases the expression of MMP-2 in the surrounding stromal cells and thus could promote angiogenesis and tumor growth resulting in macrometastatic androgen independent disease.

Abstract
OBJECTIVES Serum prostate specific antigen and digital rectal examination are the tests used as screening tests to detect prostate cancer. However, only approximately 30% of men with suspicion of cancer have it confirmed on prostate biopsy, and not all of these need treatment. Detection of circulating tumor cells in localized prostate cancer has given variable results, but it could be a useful complementary screening tool to detect prostate cancer in men with abnormal screening tests before the evaluation with prostate biopsy. This may be more so in subsequent biopsies where serum PSA has a decreased diagnostic yield. To evaluate the diagnostic yield of the detection of CPCs as a complementary PC screening test in a population fulfilling criteria for an initial, second and third prostate biopsy for suspicion of PC. METHODS A prospective screening study of consecutive patients aged 45-80 years presenting to the urologist for PC screening. Inclusion criteria were PSA >4.0 ng/ml, PSA velocity >0.35 ng/ml/year and/or DRE suspicious for cancer. Patients fulfilling inclusion criteria had blood taken for CPC detection and then underwent 12-core transrectal prostate biopsy. Double immune-his-tochemical staining with anti-PSA and anti-P504S was used to detect CPCs. Both cytologist and pathologist were blinded to the results of the biopsy, CPC results and clinical details. The diagnostic yield of the presence or absence of CPC was evaluated; the prostate biopsy was classified as cancer or no-cancer. RESULTS 282 men participated, 83 undergoing of these undergoing a second and 38 a third biopsy, with a mean age of 66.2 ± 8.9 years and a median serum PSA of 5.10 ng/ml, 5.45 ng/ml and 6.45 ng/ml for first, second and third biopsies. Cancer was detected in 33,6%, 10.8% and 29.0% of first, second and third biopsies respectively, CPCs were detected in 36.9%, 21.7% and 36.8% of the patients. Sensibility, specificity and negative predictive value were 86% ,91% and 94% for the first biopsy, 89%, 87% and 99% for the second and 100% , 89% and 100% for third biopsy respectively. All the CPC determinations were interpretable. There were 11 false negative cases, all with small low grade tumors. Of the 29 men with a false positive CPC, 8/10 had cancer detected in the subsequent biopsy. CONCLUSIONS The use of CPC detection could be useful as a complementary prostate cancer screening test, especially for excluding cancer, and including patients with indications for repeat biopsies. Men with a false positive CPC detection had a high risk of detecting cancer in the succeeding biopsy.

Abstract
IntroductionThe prevalence of psychiatric disorders in prison populations showed in other European countries has not been replicated in Spain.ObjectivesThe aim of the study was to estimate the lifetime and last month prevalence of mental disorders in a Spanish prison population sample. In this posetr we look a drug induced psychiatryc disorders found in this study.MethodThis is a descriptive cross-sectional epidemiological study. 783 male inmates were included in the study. Mental disorders were assessed with Structured Clinical Interview (SCID 1) for DSM-IV Axis 1 Disorders, clinical version and personality disorders were assessed by the Spanish version of the International Personality Disorders Examination.ResultsThe lifetime prevalence of mental disorder was 84.4%. Substance use disorder (abuse and dependence) was the most frequent disorder (76,2%): When look at substance induced diosder we found Mood induced disoder had lifetime prevalence of 15,8%(,13,2–18,5) and a last month prevalence of 2,8% (1,6–4,1), anxiety disoders were 16,1% (13,4–18,8) in lifetime prevalence and 5,9 (4,2–7,7) for last month prevalence and for subtance induce psychotic disoder lifetime prevalence was 7,1%(5,2–9,0) and last month prevalence was 2.0 (1.0–3.0). There is a 95 interval confidence on all these data.ConclusionsThe high prevalence of mental disorder and substance misuse is relevant both for the planning of health resource use in the prison environment and the prevention and approach to these disorders.

Abstract
In order to guarantee the required level of quality for our Bone &Tissue Banking, we evaluated a new CE marked container (CELLFLEX MacoPharma), for packing, transport, processing and storage of bones for therapeutic use. The use of CE marked containers is mandatory for organ and tissue containers (Medical Device Directive 93/42). We carried out a three-phase study: (1)Evaluation, (2) Implementation, (3)Audit The product was evaluated for the following criteria:Dash mechanical resistance, Dash air tightness, Dash fragility, Dash capacity. No damage was observed after the storage period, even after immersion in liquid nitrogen. No breakages were observed after provoked impact tests (pots dropped onto the floor). The pot capacity evaluation showed that the inner pot volume (approximately 500 ml) permits adequate storage of tendons and the majority of bone allografts. In conclusion, this evaluation has shown that the CELLFLEX kit is suitable for long duration preservation of bone allografts even at very low temperature conditions (vapour phase nitrogen). Its format and structure permit preservation of most bone allografts.

Abstract
INTRODUCTION Breast cancer is a disease with a very variable progression. Primary tumour size and metastatic lymph node involvement are the best indicators of the likelihood of relapse. However, their value in predicting progression following relapse is not clear. AIM The aim of this study was to asses whether the relationship between tumour size and the number of lymph nodes involved had any value as predictive factors of post-relapse progression. METHOD We established an index defined as the quotient between the number of diseased lymph nodes and the tumour size (in cm). RESULTS Applying this index in 230 consecutive patients with metastatic breast cancer, we observed that there was a significant inverse relation between the index and post-relapse progression. CONCLUSION We conclude that, at the time of initial diagnosis, the quotient of tumour size and the number of diseased lymph nodes could be a good predictor of time-to-progression following the diagnosis of the metastatic disease.

Abstract
In a single-center, open, phase II trial, we assessed the toxicity and activity of a triple combination therapy--doxorubicin at 30 mg/m2 (day 1), paclitaxel (Taxol) at 135 mg/m2 (day 2), and gemcitabine (Gemzar) at 2,500 mg/m2 (day 2 after paclitaxel)--administered biweekly in a 28-day cycle for six cycles. This was given as first-line treatment in 41 patients with metastatic breast cancer. Granulocyte colony-stimulating factor was used in 27 patients to permit maintenance of dose density. Hematologic toxicity was moderate. Nonhematologic adverse events were generally mild. The objective response rate was 82.9% (34/41) with 18 patients (43.9%) achieving complete response and 16 (38%) achieving partial response; progressive disease was observed in 4 patients (9.8%). Responses were observed at all metastatic sites, including complete responses in lung, liver, bone, and soft tissue. Median duration of response was 14.1 months and median time to progression was 13.9 months. Median survival was 26.2 months. The biweekly combination of gemcitabine, doxorubicin, and paclitaxel is safe and highly active as first-line treatment in metastatic breast cancer.
