Transforming Growth Factor-β Receptor Blockade Augments the Effectiveness of Adoptive T-Cell Therapy of Established Solid Cancers

PURPOSE: Adoptive cellular immunotherapy is a promising approach to eradicate established tumors. However, a significant hurdle in the success of cellular immunotherapy involves recently identified mechanisms of immune suppression on cytotoxic T cells at the effector phase. Transforming growth factor-beta (TGF-beta) is one of the most important of these immunosuppressive factors because it affects both T-cell and macrophage functions. We thus hypothesized that systemic blockade of TGF-beta signaling combined with adoptive T-cell transfer would enhance the effectiveness of the therapy. EXPERIMENTAL DESIGN: Flank tumors were generated in mice using the chicken ovalbumin-expressing thymoma cell line, EG7. Splenocytes from transgenic OT-1 mice (whose CD8 T cells recognize an immunodominant peptide in chicken ovalbumin) were activated in vitro and adoptively transferred into mice bearing large tumors in the presence or absence of an orally available TGF-beta receptor-I kinase blocker (SM16). RESULTS: We observed markedly smaller tumors in the group receiving the combination of SM16 chow and adoptive transfer. Additional investigation revealed that TGF-beta receptor blockade increased the persistence of adoptively transferred T cells in the spleen and lymph nodes, increased numbers of adoptively transferred T cells within tumors, increased activation of these infiltrating T cells, and altered the tumor microenvironment with a significant increase in tumor necrosis factor-alpha and decrease in arginase mRNA expression. CONCLUSIONS: We found that systemic blockade of TGF-beta receptor activity augmented the antitumor activity of adoptively transferred T cells and may thus be a useful adjunct in future clinical trials.

Die klinischen Kriterien für das Vorliegen einer nosokomialen Pneumonie sind nur begrenzt sensitiv und spezifisch. Die Diagnostik der nosokomialen Pneumonie hat daher zum Ziel, das Vorliegen einer Pneumonie zu belegen und ursächliche Erreger zu identifizieren. Dabei ist die Identifikation des Erregers beim individuellen Patienten genauso wichtig wie die Erstellung lokaler Erreger- und Resistenzspektren. Zur Gewinnung von Sekreten des tiefen Respirationstraktes stehen nichtinvasive und invasive diagnostische Methoden zur Verfügung. Zumindest die mikrobiologische Basisdiagnostik sollte im Krankenhaus selbst durchgeführt werden. Die Technik der quantitativen Kultur von Sekreten des tiefen Respirationstrakts gewährleistet unabhängig von der eingesetzten Methode eine höhere Spezifität. Die nosokomiale Pneumonie des spontan atmenden Patienten kann in der Regel mittels klinischen und nichtinvasiven Methoden ausreichend valide diagnostiziert werden. Die nosokomiale Beatmungspneumonie hingegen bedarf zumindest in Krankenhäusern der Maximalversorgung einer Untersuchung durch die quantitative Kulturtechnik. Obwohl invasiv-bronchoskopische Techniken (besonders die geschützte Bürste PSB) tendenziell eine etwas bessere Spezifität aufweisen, sind sie hinsichtlich wichtiger klinischer Endpunkte dem quantitativ aufgearbeiteten Tracheobronchialsekret nicht überlegen. Als diagnostischer Grundansatz wird daher das quantitativ aufgearbeitete Tracheobronchialsekret empfohlen. Es sollte jedoch für spezielle Indikationen sowie die Abklärung von Therapieversagern mindestens eine bronchoskopische Technik etabliert sein. Auch nichtbronchoskopische Techniken der Gewinnung einer bronchoalveolären Lavage (z. B. „mini-BAL”) können in speziellen Indikationen hilfreich sein. Die Ergebnisse der quantitativen Kulturen sind in jedem Fall im Zusammenhang mit der klinischen Situation des Patienten zu interpretieren. Dabei ist insbesondere die Vortest-Wahrscheinlichkeit des Vorliegens einer Pneumonie zu berücksichtigen. Alle diagnostischen Ansätze erfordern eine intensive und enge Zusammenarbeit von Klinikern und Mikrobiologen. Regelmäßige Qualitätskontrollen sowie Aufstellungen des Erreger- und Sensibilitätsspektrums sind dabei unerläßlich.

Many narrow QRS complex tachycardias are benign, but some require rapid intervention. The review, EKG strips, and algorithm you'll find here will help you get to the source of the problem without delay.

Ischemic cardiomyopathy is one of the most common causes of congestive heart failure. Despite multiple therapeutic options, morbidity and mortality remain high. Revascularization is one of the best options to improve ejection fraction and survival in patients with hibernating myocardium. This article discusses the role of positron emission tomography (PET), single-photon emission computed tomography (SPECT), dobutamine stress echocardiography (DSE), and magnetic resonance imaging (MRI)-based viability studies and their comparative evaluation.

Narrow QRS complex tachycardia presenting as palpitation.

Atrial fibrillation is the most common sustained cardiac arrhythmia. The rhythm in atrial fibrillation is irregular. Correct interpretation of the electrocardiogram (ECG) is essential. Atrial flutter can present as regular or irregular narrow QRS complex tachycardia. Knowledge of the ECG features of atrial flutter will help to differentiate it from paroxysmal supraventricular tachycardia. The treatment strategy in atrial fibrillation should focus on rhythm control vs. rate control, and anticoagulation should be started based on the calculated risk of systemic embolisation. Atrial flutter is a unique arrhythmia that has similar management strategies to those of atrial fibrillation; however, radiofrequency ablation is increasingly preferred due to its higher rate of efficacy and safety compared to pharmacological therapy.

This issue of Work highlights Swedish models of health care, particularly in the area of rehabilitation. It is natural, for one whose cultural and clinical experience has been concentrated in the United States, to compare and contrast the underlying assumptions of the approaches taken in the two countries.
