A randomized, open-label, multicentre, phase IV study evaluating palbociclib plus endocrine treatment versus a chemotherapy based treatment strategy …

2017

TPS1115 Background: Although endocrine based therapy is recommended as first-line treatment in metastatic breast cancer (MBC) in patients with an HER2-/HR+ tumour up to 50% of the patients receive chemotherapy. Palbociclib (P) a CDK4/6 inhibitor improves PFS by 42% in endocrine sensitive and resistant HER2-/HR+ MBC when added to an endocrine therapy (ET). Patients included in clinical trials are often criticised not to be representative for real world breast cancer patients. Methods: Patients with first-line HER2-/HR+ MBC who are candidate for mono-chemotherapy will be eligible to be randomised 1:1 to receive either P plus ET per label or mono-chemotherapy per investigator´s choice with or…

Adherence to Guidelines among Italian Urologists on Imaging Preoperative Staging of Low-Risk Prostate Cancer: Results from the MIRROR (Multicenter It…

2011

Objective. A number of evidence-based guidelines for diagnosis and management of prostate cancer have been published. The aim of this study is to evaluate the adherence of Italian urologists to the guidelines concerning the preoperative imaging staging of prostate cancer.Methods. In October 2007 a multicentric observational perspective study called Multicentric Italian Report on Radical prostatectomy Outcome and Research (MIRROR) was started in 135 Italian urology centers. Recruitment was closed in December 2008 and 2,408 cases were collected. In this paper we have taken into consideration all examinations carried out for preoperative imaging staging, evaluating compliance with the recommen…

Hipertensión arterial episódica asociada al síndrome de taquicardia postural ortostática

2006

Se presenta el caso clínico de una mujer de 17 años de edad que acude en reiteradas ocasiones a urgencias por palpitaciones, taquicardia, síncope, reacción vegetativa de escasa duración, con recuperación espontánea y completa y detección de cifras elevadas de presión arterial. Estudiada en diversas consultas de especialidades y tras múltiples exploraciones complementarias no se encontró patología que justificase el cuadro. Ante la sospecha de intolerancia ortostática o síndrome de taquicardia postural ortostática con hipertensión se realizó la prueba de estimulación con cama basculante a 60°, confirmándose el diagnóstico y comprobando la desaparición de los síntomas al iniciar tratamiento c…

Eine 22-jährige Mutter mit starkem Juckreiz und zunehmendem Ikterus zwei Wochen nach Beginn der hormonalen Kontrazeption

2016

Eine intermittierend auftretende cholestatische Lebererkrankung kann einen angeborenen Defekt im Bereich der Gallensaurentransportproteine offenlegen. Die Episoden konnen durch eine Schwangerschaft oder die Einnahme oraler Kontrazeptiva oder anderer Medikamente ausgelost werden. Wir beschreiben den Fall einer 22-jahrigen Mutter, bei der zwei Wochen nach Beginn der hormonalen Kontrazeption ein zunehmender Ikterus und schwerer Juckreiz auftrat. Bereits einige Monate zuvor hatte sie an Juckreiz im Rahmen einer intrahepatischen Schwangerschaftscholestase gelitten. Die Leberbiopsie zeigte eine Cholestase in unauffalligem Lebergewebe. Die Behandlung mit Ursodesoxycholsaure war nicht erfolgreich. …

Strong N−X⋅⋅⋅O−N Halogen Bonds: A Comprehensive Study on N‐Halosaccharin Pyridine N ‐Oxide Complexes

2019

A study of the strong N-X⋅⋅⋅- O-N+ (X=I, Br) halogen bonding interactions reports 2×27 donor×acceptor complexes of N-halosaccharins and pyridine N-oxides (PyNO). DFT calculations were used to investigate the X⋅⋅⋅O halogen bond (XB) interaction energies in 54 complexes. A simplified computationally fast electrostatic model was developed for predicting the X⋅⋅⋅O XBs. The XB interaction energies vary from -47.5 to -120.3 kJ mol-1 ; the strongest N-I⋅⋅⋅- O-N+ XBs approaching those of 3-center-4-electron [N-I-N]+ halogen-bonded systems (ca. 160 kJ mol-1 ). 1 H NMR association constants (KXB ) determined in CDCl3 and [D6 ]acetone vary from 2.0×100 to >108  m-1 and correlate well with the calculat…

This study aimed to explore the acute effects of static stretching on the musculotendinous properties of two hamstring muscles. Twelve male volunteers underwent two testing sessions. One session was dedicated to the evaluation of the semitendinosus muscle before (PRE) and after (POST) static stretching (five sets of 30-s stretching), and the other session similarly explored the long head of biceps femoris muscle. In addition to the displacement of the myotendinous junction (MTJ), passive torque and maximal voluntary isometric torque (MVIT) were evaluated. MVIT (−8.3 ± 10.2%, p = 0.0036, d = 0.497) and passive torque (−28.4 ± 16.9%, p = 0.0003, d = 1.017) were significantly decreased POST st…

Quantification of Recruit Training Demands and Subjective Wellbeing during Basic Military Training

2022

Purpose: Assess and describe the physical demands and changes in subjective wellbeing of recruits completing the 12 week Australian Army Basic Military Training (BMT) course. Methods: Thirty-five recruits (24.8 ± 6.8 y; 177.4 ± 10.1 cm, 75.6 ± 14.7 kg) consented to daily activity monitoring and weekly measures of subjective wellbeing (Multi-component Training Distress Scale, MTDS). The physical demands of training were assessed via wrist worn activity monitors (Actigraph GT9X accelerometer). Physical fitness changes were assessed by push-ups, sit-ups and multi-stage shuttle run in weeks 2 and 8. Results: All objective and subjective measures significantly changed (p &lt…

Reduced inotropic support after aprotinin therapy during pediatric cardiac operations

1999

Several reports indicate that aprotinin treatment before and during cardiopulmonary bypass (CPB) might have a protective effect on the myocardium. We evaluated the hemodynamic effects of perioperative aprotinin treatment.We conducted a randomized, double-blind, placebo-controlled trial in 34 infants (mean age, 2.5 years) who had cardiac operations. Half of the patients received high-dose aprotinin therapy. There were no significant differences between the aprotinin and placebo groups with respect to age, weight, sex, aortic cross-clamp time, and CPB time. The following data were recorded at arrival in the intensive care unit 6, 12, 24, and 48 hours after termination of CPB: heart rate, bloo…

Effect of hemostatic agent on marginal gaps of class V giomer restorations

2017

Background Contamination of dentin with hemostatic agents might exert a deleterious effect on adhesive procedures on dentin. The present study was undertaken to investigate the effect of aluminum chloride hemostatic agent on marginal gaps in Cl V giomer restorations. Material and Methods Fifty sound bovine permanent incisors were selected for the purpose of this in vitro study and Cl V cavities were prepared on their buccal surfaces; the gingival margins of the cavities were placed in dentin. The tooth samples were randomly assigned to two groups (n=25). The samples in groups 1 and 2 underwent a restorative procedure without and with the application of aluminum chloride hemostatic agent in …
