Rationale and study design of the RESERVOIR trial: a randomized trial comparing reservoir-based polymer-free amphilimus-eluting stents versus everolimus-eluting stents with durable polymer in patients with diabetes mellitus.

BACKGROUND: Patients with diabetes mellitus (DM) remain at high risk for stent restenosis and adverse cardiovascular events in the drug-eluting stent era. The amphilimus-eluting stent (AES) is a third generation reservoir-based polymer-free drug-eluting stent that has shown promising preliminary results in patients with DM. It has been suggested that the formulation of the drug with fatty acids could not only modulate the drug release in a timely manner but also achieve convenient levels of drug concentration in diabetic cardiac cells. The aim of this trial is to assess the efficacy of the AES in patients with DM compared with the cobalt chromium everolimus-eluting stent with non-erodible polymer (EES). STUDY DESIGN: This is an investigator-initiated, multicenter, randomized clinical trial, performed in patients with DM. A total of 112 diabetic patients receiving glucose-lowering agents and requiring percutaneous revascularization of a de novo lesion will be randomized in a 1:1 fashion to receive AES or EES. The primary endpoint is the neointimal volume obstruction at 9 months, evaluated by optical coherence tomography. Secondary endpoints will include strut coverage, angiographic in-stent late loss and clinical endpoints such as target vessel revascularization or probable/definite stent thrombosis. This study completed the inclusion in October 2013. CONCLUSIONS: The RESERVOIR trial is an investigator-initiated trial that will evaluate whether the polymer-free AES is not inferior to the EES inhibiting the neointimal hyperplasia in patients with DM. These results are also expected to improve our knowledge of the neointimal healing process in this population (Clinicaltrials.gov number NCT01710748).

Dinámica de la córticoangiogénesis en el sistema nervioso central / Dinamics of the cortico-angiogenesis in the central nervous system

This study analyzes the temporal-spatial correlation between angio-and corticogenesis in the developing chick optic tectum (OT) by means of NADPH-diaphorase and immunolabeling methods. Qualitative and quantitative parameters were used to analyze a new vessels formation and growth of preexisting ones as a function of time and space...

Late outcome of Senning and Mustard procedures for correction of transposition of the great arteries.

OBJECTIVES: To evaluate late mortality and morbidity after an atrial switch procedure for correction of transposition of the great arteries (TGA) and to assess predictive factors for adverse outcome. SETTING: Tertiary referral centre. DESIGN AND PATIENTS: Retrospective follow up study of 137 patients surviving hospitalisation for TGA atrial switch procedure (Mustard or Senning) in a single institution and divided into two groups (simple and complex) depending on presurgical anatomy. Several surgical and follow up factors were evaluated during 16.7 (5.6) years' follow up. RESULTS: Late mortality was 5.1% (95% confidence interval 1.37% to 8.84%) with sudden death as the most common cause. No significant difference was found between Mustard and Senning procedures and between the complex and simple groups in terms of mortality. Independent predictive factors for late mortality were a history of supraventricular tachyarrhythmias and advanced New York Heart Association (NYHA) functional class during follow up. A very common finding was development of sinus node dysfunction (47.6%), which had no influence on mortality. There was little need for reintervention (5.1%) and relatively few cases of right ventricular systolic dysfunction (14.6%). During follow up, most patients (96.2%) were in NYHA functional class I-II. CONCLUSIONS: Overall long term outcomes of patients with atrial repair of TGA in the present era are encouraging in terms of late mortality and quality of life. Nevertheless, better outcomes may be offered through improved diagnostic methods for right ventricular function and better management of supraventricular tachyarrhythmias.

[Relationship between malingered psychometric profiles and personality styles in prisoners]. / Perfiles psicométricos fingidos en relación con estilos de personalidad en reclusos.

INTRODUCTION: One of the most typical clinical problems is the assessment of malingering in the field of forensic and penitentiary psychiatry. OBJECTIVE: The purpose of this research was to find associations between different personality types and psychometric response styles. MATERIAL AND METHODS. SUBJECTS: participants consisted of 41 imprisoned male offenders. Instruments and data collection: the psychometric tools used were the Millon Clinical Multiaxial Inventory (MCMI-II) and the Minnesota Multiphasic Personality Inventory (MMPI-2). STATISTICS: data were analyzed with the Statistical Package for the Social Sciences (SPSS, version 10.0). A p < 0.05 significance level was proposed. RESULTS: There is significant correlation between personality types and styles of responses in the inventories. CONCLUSIONS: The greatest relationships were found between personality types shaping cluster B of DSM-IV-TR and validity indexes that measure malingering as response style.

Discriminating deliberate self-harm (DSH) in young prison inmates through personality disorder.

This study investigated deliberate self-harm (DSH) in young inmates. The objectives are twofold: first, to identify the social and clinical characteristics of inmates who commit DSH; and secondly, to ascertain the types of personality who are vulnerable in order to be able to predict future inmates who may harm themselves. A cross-sectional design was used to study psychosocial correctional personality characteristics and clinical pictures in inmates with DSH versus a control group without DSH. The measures used to evaluate different variables were a standard protocol and a self-report questionnaire (MCMI-II). Although the two groups compared are homogeneous and similar in terms of different psychosocial variables, inmates with DSH presented a significant background of maltreatment. Borderline, passive-aggressive, and antisocial personality disorders best discriminated both groups. The detection of borderline, negativistic, and antisocial disorders may help the medical services of penitentiary centers to predict youths with a possible risk of DSH. Despite the results obtained, longitudinal studies are needed to help clarify other risk factors, as well as other risk factors leading to self-harm behavior.

An unusual, highly aggressive, anaplastic carcinoma of the nasal cavity.

The case of a patient who had a rapidly growing anaplastic carcinoma of the nasal cavity is reported. The patient died from local recurrences, regional lymph nodes, and distant pulmonary metastases within seven months of the initial diagnosis.
