Prostate-specific Antigen at 3 Months as a Predictor of Radiologic Progression-free Survival in Metastatic Hormone-sensitive Prostate Cancer Treated with Apalutamide: Analysis of 633 Patients in a Real-world Database.

Background And Objective: The depth of the prostate-specific antigen (PSA) decline after androgen receptor pathway inhibitor (ARPI) treatment combined with androgen deprivation therapy for patients with metastatic hormone-sensitive prostate cancer (mHSPC) may affect prognosis. The primary objective in our study was the correlation between the PSA response at 3 mo and radiologic progression-free survival (rPFS) at 24 mo. Three groups were defined according to the PSA decline: complete response (PSA ≤0.

Ultralow Prostate-Specific Antigen (PSA) Levels and Improved Oncological Outcomes in Metastatic Hormone-Sensitive Prostate Cancer (mHSPC) Patients Treated with Apalutamide: A Real-World Multicentre Study.

Androgen receptor-targeted agents have significantly improved the prognosis of metastatic hormone-sensitive prostate cancer (mHSPC). Prostate-specific antigen (PSA) levels are key prognostic markers, with rapid and deep reductions associated with better outcomes. This study aims to assess the association between the new PSA cut-offs and survival in mHSPC patients treated with Apalutamide.

Real-world prostate-specific antigen reduction and survival outcomes of metastatic hormone-sensitive prostate cancer patients treated with apalutamide: An observational, retrospective, and multicentre study.

Background: Metastatic hormone-sensitive prostate cancer (mHSPC) treatment has changed drastically during the last years with the emergence of androgen receptor-targeted agents (ARTAs). ARTA combined with androgen deprivation therapy has demonstrated better oncological and survival outcomes in these patients. However, the optimal choice among different ARTAs remains uncertain due to their analogous efficacy.

Phase II Trial Evaluating Olaparib Maintenance in Patients with Metastatic Castration-Resistant Prostate Cancer Responsive or Stabilized on Docetaxel Treatment: SOGUG-IMANOL Study.

The SOGUG-IMANOL trial was a phase 2, uncontrolled, Spanish multicenter study to assess the effect of maintenance treatment with olaparib on radiographic progression-free survival (PFS) in patients with metastatic castration-resistant prostate cancer (mCRPC) who achieved partial or complete response or disease stabilization on docetaxel treatment and had a documented germline/somatic mutation in any of the homologous recombination repair (HRR) genes. Patients received olaparib 300 mg orally twice daily. From the screened population ( = 134), 26 (19.

A Newborn Screening Program for Sickle Cell Disease in Murcia (Spain).

Sickle cell disease (SCD) is an inherited autosomal recessive hemoglobin disorder caused by the presence of hemoglobin S, a mutant abnormal hemoglobin caused by a nucleotide change in codon 6 of the β-globin chain gene. SCD involves a chronic inflammatory state, exacerbated during vaso-occlusive crises, which leads to end-organ damage that occurs throughout the lifespan. SCD is associated with premature mortality in the first years of life.

Impact of concurrent tumour events on the prostate cancer outcomes of germline BRCA2 mutation carriers.

Background: Several studies have reported the association of germline BRCA2 (gBRCA2) mutations with poor clinical outcomes in prostate cancer (PCa), but the impact of concurrent somatic events on gBRCA2 carriers survival and disease progression is unknown.

Patients And Methods: To ascertain the role of frequent somatic genomic alterations and histology subtypes in the outcomes of gBRCA2 mutation carriers and non-carriers, we correlated the tumour characteristics and clinical outcomes of 73 gBRCA2 and 127 non-carriers. Fluorescent in-situ hybridisation and next-generation sequencing were used to detect copy number variations in BRCA2, RB1, MYC and PTEN.

Phenotypic characterization of a pediatric cohort with cystinuria and usefulness of newborn screening.

Background: Cystinuria is an inherited metabolic disease involving the defective transport of cystine and the dibasic amino acids in the renal proximal tubules that causes the formation of stones in the urinary system. In our regional child health program, cystinuria is included in newborn metabolic screening. Our objectives are the phenotypic characterization of our cystinuric pediatric cohort and to present our experience in neonatal cystinuria screening.

A phase II randomised trial of abiraterone acetate plus prednisone in combination with docetaxel or docetaxel plus prednisone after disease progression to abiraterone acetate plus prednisone in patients with metastatic castration-resistant prostate cancer: The ABIDO-SOGUG trial.

Background: We aimed to compare the efficacy and safety of maintaining or withdrawing abiraterone acetate plus prednisone (AAP) in patients with metastatic castration-resistant prostate cancer who had experienced cancer progression to this treatment and were beginning a docetaxel-based therapy.

Patients And Methods: Phase II, randomised, open-label study conducted in patients with metastatic castration-resistant prostate cancer who were asymptomatic or mildly symptomatic. After open-label treatment with AAP, patients who had experienced cancer progression to AAP were randomised to 75 mg/m of docetaxel plus AAP or to receive 75 mg/m of docetaxel plus 10 mg of prednisone orally daily.

Sunitinib rechallenge in advanced renal cell carcinoma: outcomes of a multicenter retrospective study.

Purpose: The aim of this multicenter study was to evaluate the clinical outcomes of patients with metastatic renal cell carcinoma (mRCC) who received sunitinib retreatment.

Methods: Clinical data from patients treated with sunitinib rechallenge in nine Spanish centers were retrospectively analyzed. All patients received first-line sunitinib until progression or intolerance, followed by one or more successive drugs and rechallenge with sunitinib thereafter.

Newborn screening for homocystinurias: Recent recommendations versus current practice.

Purpose: To assess how the current practice of newborn screening (NBS) for homocystinurias compares with published recommendations.

Methods: Twenty-two of 32 NBS programmes from 18 countries screened for at least one form of homocystinuria. Centres provided pseudonymised NBS data from patients with cystathionine beta-synthase deficiency (CBSD, n = 19), methionine adenosyltransferase I/III deficiency (MATI/IIID, n = 28), combined remethylation disorder (cRMD, n = 56) and isolated remethylation disorder (iRMD), including methylenetetrahydrofolate reductase deficiency (MTHFRD) (n = 8).

Weekly cabazitaxel plus prednisone is effective and less toxic for 'unfit' metastatic castration-resistant prostate cancer: Phase II Spanish Oncology Genitourinary Group (SOGUG) trial.

Aim: Cabazitaxel (CBZ), a novel tubulin-binding taxane, improves overall survival in metastatic castration-resistant prostate cancer (mCRPC) that progresses during or after docetaxel treatment. We have designed a phase II study to evaluate the efficacy and safety of CBZ as a weekly schedule for 'unfit' mCRPC patients after docetaxel failure.

Methods: In this single arm phase II study.

PREPL deficiency: delineation of the phenotype and development of a functional blood assay.

PurposePREPL deficiency causes neonatal hypotonia, ptosis, neonatal feeding difficulties, childhood obesity, xerostomia, and growth hormone deficiency. Different recessive contiguous gene deletion syndromes involving PREPL and a variable combination of SLC3A1 (hypotonia-cystinuria syndrome), CAMKMT (atypical hypotonia-cystinuria syndrome), and PPM1B (2p21 deletion syndrome) have been described. In isolated PREPL deficiency, previously described only once, the absence of cystinuria complicates the diagnosis.

Novel potential predictive markers of sunitinib outcomes in long-term responders versus primary refractory patients with metastatic clear-cell renal cell carcinoma.

Background: Several potential predictive markers of efficacy of targeted agents in patients with metastatic renal cell carcinoma (mRCC) have been identified. Interindividual heterogeneity warrants further investigation.

Patients And Methods: Multicenter, observational, retrospective study in patients with clear-cell mRCC treated with sunitinib.

Relationship of immunohistochemistry, copy number aberrations and epigenetic disorders with BRCAness pattern in hereditary and sporadic breast cancer.

The study aims to identify the relevance of immunohistochemistry (IHC), copy number aberrations (CNA) and epigenetic disorders in BRCAness breast cancers (BCs). We studied 95 paraffin included BCs, of which 41 carried BRCA1/BRCA2 germline mutations and 54 were non hereditary (BRCAX/Sporadic). Samples were assessed for BRCA1ness and CNAs by Multiplex Ligation-dependent Probe Amplification (MLPA); promoter methylation (PM) was assessed by methylation-specific-MLPA and the expression of miR-4417, miR-423-3p, miR-590-5p and miR-187-3p by quantitative RT-PCR.

Mammographic density and breast cancer in women from high risk families.

Introduction: Mammographic density (MD) is one of the strongest determinants of sporadic breast cancer (BC). In this study, we compared MD in BRCA1/2 mutation carriers and non-carriers from BRCA1/2 mutation-positive families and investigated the association between MD and BC among BRCA1/2 mutation carriers per type of mutation and tumor subtype.

Methods: The study was carried out in 1039 female members of BRCA1 and BRCA2 mutation-positive families followed at 16 Spanish Genetic Counseling Units.

MicroRNA signatures in hereditary breast cancer.

This study aims to identify signatures of miR associated with hereditary, BRCA1 or BRCA2 mutation positive breast cancer (BC), and non-hereditary BC, either sporadic (SBC) or non-informative (BRCAX). Moreover, we search for signatures associated with tumor stage, immunohistochemistry and tumor molecular profile. Twenty formalin fixed paraffin embedded (FFPE) BCs, BRCA1, BRCA2, BRCAX and SBC, five per group were studied.

[Expanded newborn screening in the Region of Murcia, Spain. Three-years experience].

Background And Objective: The early detection of inborn errors of metabolism by mass spectrometry allows expanding the traditional neonatal screening of phenylketonuria and congenital hypothyroidism to test for aminoacidopathies, fatty acid oxidation disorders and organic acid metabolic disorders. Cystic fibrosis and biotinidase deficiency screening is implemented in the Region of Murcia. The aim of the study is to describe our experience in the expanded neonatal screening and to define the prevalence of each of the metabolic disorders early detected.

Diazepam enhances inotropic responses to dopamine in rat ventricular myocardium.

Diazepam inhibits phosphodiesterase type 4 and enhances the effect of some 3',5'-cyclic adenosine monophosphate (cAMP)-dependent positive inotropic drugs. We sought to determine whether diazepam and the selective phosphodiesterase type 4 inhibitor rolipram enhances the contractile response and cAMP levels induced by dopamine in rat myocardium. Dopamine (3-100 microM) produced concentration-dependent positive inotropic effects (-log EC50 = 5.

The phosphodiesterase 3 inhibitor cilostamide enhances inotropic responses to glucagon but not to dobutamine in rat ventricular myocardium.

The effects of phosphodiesterase (PDE) inhibitors (1-3) on tissue cAMP concentrations and the inotropic responses to dobutamine and glucagon were investigated in electrically driven right ventricular strips of the rat heart. Dobutamine (0.3-100 microM) produced a concentration-dependent positive inotropic effect which was not affected by 50 nM (+/-)-1-(2,3-(dihydro-7-methyl-1H-inden-4-yl)oxy)-3-((1-methylethyl)amino)-2-butanol hydrochloride (ICI 118551), a beta2-receptor antagonist, but was virtually abolished by 0.

Rolipram reduces the inotropic tachyphylaxis of glucagon in rat ventricular myocardium.

Glucagon increases cardiac contractility through G(s) protein-coupled glucagon receptors, but the inotropic responses fade. The fade could be due to receptor desensitisation or to the action of phosphodiesterases (PDE), or to both mechanisms. We investigated the effects of the PDE4 inhibitor rolipram (1 microM) on the inotropic and cAMP-responses to glucagon in paced right ventricular strips of the rat heart.

Comparative actions of diazepam and other phosphodiesterase inhibitors on the effects of noradrenaline in rat myocardium.

Diazepam inhibits different isoforms of the enzyme cyclic nucleotide phosphodiesterase and also potentiates the inotropic effect of endogenous catecholamines in rat heart. In the present study we have examined whether this late effect is the consequence of inhibition of a phosphodiesterase subtype or whether inhibition of several phosphodiesterase subtypes is involved. We compared the effect of diazepam with that of the selective inhibitors of phosphodiesterase1 (MIMX), phosphodiesterase2 (EHNA), phosphodiesterase3 (milrinone) and phosphodiesterase4 (rolipram) on the inotropic effect of noradrenaline in rat ventricle.
