RGD-based strategies for selective delivery of therapeutics and imaging agents to the tumour vasculature

During the past decade, RGD-peptides have become a popular tool for the targeting of drugs and imaging agents to alphavbeta3-integrin expressing tumour vasculature. RGD-peptides have been introduced by recombinant means into therapeutic proteins and viruses. Chemical means have been applied to couple RGD-peptides and RGD-mimetics to liposomes, polymers, peptides, small molecule drugs and radiotracers. Some of these products show impressive results in preclinical animal models and a RGD targeted radiotracer has already successfully been tested in humans for the visualization of alphavbeta3-integrin, which demonstrates the feasibility of this approach. This review will summarize the structural requirements for RGD-peptides and RGD-mimetics as ligands for alphavbeta3. We will show how they have been introduced in the various types of constructs by chemical and recombinant techniques. The importance of multivalent RGD-constructs for high affinity binding and internalization will be highlighted. Furthermore the in vitro and in vivo efficacy of RGD-targeted therapeutics and diagnostics reported in recent years will be reviewed.     

Hepatic falciform ligament artery: angiographic anatomy and clinical importance

Summary The hepatic falciform ligament artery (HFLA) was evaluated by angiography and also by dissections. Based on the findings, the mechanism of the post-chemoembolization skin rash was studied. A total of 340 liver cirrhosis patients who underwent hepatic artery chemoembolization for hepatocellular carcinoma were reviewed in terms of the angiographic incidence of the HFLA, variations in its origin, and the incidence of skin rash. The HFLA was demonstrated in 26 (7.6%) of the 340 patients on angiography. Two HFLAs were observed in one patient. The origin was the middle hepatic artery (A4) in 16 cases, the superior branch of the middle hepatic artery in three, the inferior branch of the middle hepatic artery in two, the inferior branch of the left hepatic artery (A3) in three, and the confluence of A3 and A4 in three cases. There were no patients who developed post-chemoembolization skin rash. Two cadavers were dissected to investigate the anastomosis between the HFLA and the subcutaneous artery. Two different anastomoses were found: (1) direct and (2) via the ensiform branch of the internal thoracic artery. These were located at the lower and upper part of the falciform ligament, respectively. The distribution of a chemotherapeutic agent through these anastomoses is the likely cause of post-chemoembolization skin rash. If prophylactic embolization of the proximal portion of the HFLA using a metallic coil is performed, the skin rash will be prevented.

L'artère du ligament rond du foie : anatomie angiographique et implication clinique

Résumé L'artère du ligament falciforme hépatique (ALFH) fut étudiée par des angiographies et des dissections. D'après les résultats, le mécanisme d'un rash cutané après chimio-embolisation est discuté. Un total de 340 patients présentant une cirrhose hépatique ayant eu une chimio-embolisation de l'artère hépatique pour un carcinome hépato-cellulaire fut revu en fonction de l'incidence angiographie de l'ALFH, les variations d'origine de l'ALFH, et l'incidence d'un rash cutané. L'ALFH fut objectivée angiographiquement chez 26 (7,6%) des 340 patients. Deux ALFH furent objectivées chez un patient. L'origine des ALFH était située sur l'artère hépatique moyenne (A4) dans 16 cas, la branche supérieure de l'artère hépatique moyenne dans 3 cas, la branche inférieure de l'artère hépatique moyenne dans 2 cas, la branche inférieure de l'artère hépatique gauche (A3) dans 3 cas, et la confluence A3 et A4 dans 3 cas. Aucun patient ne développa un rash cutané après chimio-embolisation. Deux cadavres furent disséqués pour étudier les anastomoses entre l'ALFH et les artères sous-cutanées. Deux types d'anastomoses entre l'ALFH et des artères sous-cutanées furent individualisés directement et par l'intermédiaire de l'artère xiphoïde et de l'artère thoracique interne. Celles-ci étaient respectivement situées à la partie inférieure et à la partie supérieure du ligament falciforme. La distribution de l'agent chimiothérapique par ces anastomoses est vraisemblablement la cause des rash cutanés après chimio-embolisation. Dans le cas d'une embolisation prophylactique de la portion proximale de l'ALFH par utilisation d'un coil métallique le rash cutané pourrait être prévenu.

Compartment syndrome. Exclusively the result of increased pressure in the muscular compartment?

Summary The compartment syndrome (cs) is characterized by an increased tissue pressure in a limited space. Pathophysiologically, it is a multifactorial disease that is potentially induced by an initial trauma and develops according to the existence of cofactors. Cofactors are, for instance, the circulation of the patient and the initial treatment of the impending cs. In particular, the microcirculation is altered with endothelial destruction, development of a capillary leak, protein loss from intravasal space and the development of an interstitial and intracellular third space. An impaired drainage of the lymphatic and venous system causes a venous infarction. An arterial infarction results if the tissue pressure exceeds the arteriolar pressure. An accompanying ischemia reperfusion mechanism increases the trauma load. In disadvantageous cases, the patients are in danger of developing a multi-organ deficiency syndrome (MODS) by an uncontrolled inflammatory reaction, by intravasal volume loss and by a myonephropathic systemic reaction. Clinically, the patients suffer a disproportionate amount of pain, followed by neurological signs. Especially in noncompliant patients, tissue pressure measurement is useful. Resuscitation of the circulation as well as splitting of casts is important. In case of a manifest cs, dermatofasciotomy has to be performed as an emergency operation. Even if cs is diagnosed early and fasciotomy is carried out early, the development of sequellae cannot be avoided in every single case.      

Creating a place for population health: Interpreting the spaces of a new School in Auckland,New Zealand

Although the reconfiguring of health care within the hospital sector has gained considerable attention by social scientists, the tertiary education sector's response to new health philosophies and practices has proceeded largely unexamined. This paper considers the new School of Population Health at the University of Auckland, accounts for its origins and considers the synergies between its design and workplace organisation. The results of a thematic analysis of narratives offered by 24 employees collected in 2004 are then presented. Findings suggest that the amassing of academics from a range of health-related backgrounds is advancing interdisciplinary dialogue even if the nature and purpose of population health remains unclear to some. A key concern of respondents was the openness of the workplace which encourages a collaborative atmosphere but also generates distraction. The degree to which conduct within the new building is perceived as regulated was also of concern. Place clearly matters in the story of the new School: the form of the building (featuring an architecture of openness) complements its function (generating new collaborations and creative thinking about health). However, the question of how ‘salutogenic’ a setting it is remains contested.
