Images in intervention Sequential contralateral injection through the same transradial vascular approach in a chronic total occlusion

Maria C. Ferrer-Gracia, Jose A. Linares, Jose R. Ruiz
2015 Advances in Interventional Cardiology  
Contralateral injection has been described as a useful tool in the treatment of chronic total occlusions (CTOs) to evaluate the distal segments of the occluded artery [1, 2] . This case shows that contralateral injections are feasible through just one puncture using a 6 Fr sheath, a long guidewire of 0.014" and a 5 Fr diagnosis catheter in parallel. We present a 64-year-old man with severe peripheral vasculopathy. Coronary angiography showed a chronic total occlusion at the left circumflex

Percutaneous coronaty intervention (PCI) was performed through a 6 Fr sheath placed in the right radial artery. We began the procedure treating the left circumflex artery occlusion with an EBU 3.5 6 Fr guiding catheter and an Asahi Sion "J" guidewire which crossed the occlusion easily. However, after dilatations with a 2.5 × 15 mm balloon, no distal filling was observed (Figure 1 A) . We changed the first angioplasty guidewire for a 0.014" 300 cm length BMW guidewire. We passed in parallel a regular wire (0.035" 260 cm J) inside the guide catheter until it reached the aortic root. Then, using the same sheath, we changed to a JR 5 Fr diagnosis catheter to perform a contralateral injection. The injection from the right coronary artery showed that the guidewire was placed successfully in the marginal branch (Figure 1 B) . After that we advanced the previous guiding catheter using again the regular guide in the aortic root while still maintaining the 0.014" BMW 300 cm in the marginal branch. Needing buddy-wire technique, a 2.5 × 33 mm everolimus drug-eluting stent was successfully deployed in the middle segment of the circumflex artery towards the marginal branch, and another similar 2.25 × 18 mm stent distally to the previous one (Figure 1 C) . Thereafter the collateral circulation to the marginal branch disappeared. This case shows that contralateral injections are feasible through a unique puncture site using a 6 Fr sheath, a long guidewire of 0.014" placed in the endpoint branch and a 5 Fr diagnosis catheter in parallel. The 0.035" 260 cm J regular wire placed in the aortic root helps to change catheters, improving the softness of the angioplasty guidewire (and avoiding its prolapse in the coronary artery). Recently there have been published reports of two different ways to perform bilateral angiography in a single radial access once the wires had crossed the CTO but it was uncertain whether the wires were in the true lumen. The first one, called BASIRALA (bilateral angiography in a single radial access) [3], uses a microcatheter to inject selectively in the donor branches connected with CTOs. The second one [4] involves injecting with the same multipurpose guiding catheter in which the operator creates a loop of the wire in the coronary sinus and ascending aorta. This looped wire allows the catheter to be turned towards the contralateral artery without disengagement of the wire. None of these three techniques can offer a real simultaneous contralateral injection. It is possible, simple and safe to perform contralateral injections using a parallel long angioplasty 0.014" guidewire and a diagnosis catheter one French smaller than the sheath. The use of one 0.035" 260 cm regular wire helps during catheter exchanges.

2009 Annals of Clinical Microbiology and Antimicrobials  
Vibrio spp. is a pathogen rarely isolated in cancer patients, and in most cases it is associated with haematological diseases. Cutaneous manifestations of this organism are even rarer. We report a case of Non-O1 Vibrio cholerae inguinal skin and soft tissue infection presenting bullous skin lesions in a young type II diabetic patient with a penis squamous cell carcinoma having a seawater exposure history.

2010 Globalization and Health  
This paper draws together contributions to a scientific table discussion on obesity at the European Science Open Forum 2008 which took place in Barcelona, Spain. Socioeconomic dimensions of global obesity, including those factors promoting it, those surrounding the social perceptions of obesity and those related to integral public health solutions, are discussed. It argues that although scientific accounts of obesity point to large-scale changes in dietary and physical environments, media

While the debate at the forum brought together a diversity of views, all the contributors agreed that this was a global issue requiring an equally global response. Furthermore, an integrated ecological model of obesity proposes that to be effective, policy will need to address not only human health but also planetary health, and that therefore, public health and environmental policies coincide.

Neurodegenerative diseases present a current challenge for accurate diagnosis and for providing precise prognostic information. Developing imaging biomarkers for multiple sclerosis (MS), Parkinson disease (PD), and Alzheimer's disease (AD) will improve the clinical management of these patients and may be useful for monitoring treatment effectiveness.

Retinal thinning has been observed in these patients and new segmentation software for the analysis of the different retinal layers may provide accurate information on disease progression and prognosis. In this review we analyze the application of retinal evaluation using OCT technology to provide better understanding of the possible role of the retinal layers thickness as biomarker for the detection of these neurodegenerative pathologies. Current OCT analysis of the retinal nerve fiber layer and, specially, the ganglion cell layer thickness may be considered as a good biomarker for disease diagnosis, severity, and progression.

2020 bioRxiv   pre-print
α-Synuclein amyloid self-assembly is the hallmark of a number of neurodegenerative disorders, including Parkinson's disease, although there is still very limited understanding about the factors and mechanisms that trigger this process. Primary nucleation has been observed to be initiated in vitro at hydrophobic/hydrophilic interfaces by heterogeneous nucleation generating parallel β-sheet aggregates, although no such interfaces have yet been identified in vivo. In this work, we have discovered
more » ... hat α-synuclein can self-assemble into amyloid aggregates by homogeneous nucleation, without the need of an active surface, and with a preference for an antiparallel β-sheet arrangement. This particular structure has been previously proposed to be distinctive of stable toxic oligomers and we here demonstrate that it indeed represents the most stable structure of the preferred amyloid pathway triggered by homogeneous nucleation under limited hydration conditions, including those encountered inside α-synuclein droplets generated by liquid-liquid phase separation. In addition, our results highlight the key role that water plays not only in modulating the transition free energy of amyloid nucleation, and thus governing the initiation of the process, but also in dictating the type of preferred primary nucleation and the type of amyloid polymorph generated depending on the extent of protein hydration. These findings are particularly relevant in the context of in vivo α-synuclein aggregation where the protein can encounter a variety of hydration conditions in different cellular microenvironments, including the vicinity of lipid membranes or the interior of membraneless compartments, which could lead to the formation of remarkably different amyloid polymorphs by either heterogeneous or homogeneous nucleation.

Lipid droplets (LDs) are organelles that coordinate lipid storage and mobilization, both processes being especially important in cells specialized in managing fat, the adipocytes. Proteomic analyses of LDs have consistently identified the small GTPase Rab18 as a component of the LD coat. However, the specific contribution of Rab18 to adipocyte function remains to be elucidated. Herein, we have analyzed Rab18 expression, intracellular localization and function in relation to the metabolic status

In addition, our data show that insulin induces, via phosphatidylinositol 3-kinase (PI3K), the recruitment of Rab18 to the surface of LDs. Furthermore, Rab18 overexpression increased basal lipogenesis and Rab18 silencing impaired the lipogenic response to insulin, thereby suggesting that this GTPase promotes fat accumulation in adipocytes. On the other hand, studies of the badrenergic receptor agonist isoproterenol confirmed and extended previous evidence for the participation of Rab18 in lipolysis. Together, our data support the view that Rab18 is a common mediator of lipolysis and lipogenesis and suggests that the endoplasmic reticulum (ER) is the link that enables Rab18 action on these two processes. Finally, we describe, for the first time, the presence of Rab18 in human adipose tissue, wherein the expression of this GTPase exhibits sex-and depot-specific differences and is correlated to obesity. Taken together, these findings indicate that Rab18 is involved in insulin-mediated lipogenesis, as well as in b-adrenergic-induced lipolysis, likely facilitating interaction of LDs with ER membranes and the exchange of lipids between these compartments. A role for Rab18 in the regulation of adipocyte biology under both normal and pathological conditions is proposed.

AbstractObjectiveHealthy lifestyle habits are the cornerstone in the management of familial hypercholesterolaemia (FH). Nevertheless, dietary studies on FH-affected populations are scarce. The present study analyses dietary habits, adherence to a Mediterranean diet pattern and physical activity in an adult population with FH and compares them with their non-affected relatives.DesignCross-sectional study.SettingData came from SAFEHEART, a nationwide study in Spain.ParticipantsIndividuals (n

Food consumption was evaluated using a validated FFQ.ResultsTotal energy intake was lower in FH patients v. non-affected relatives (P<0·005). Percentage of energy from fats was also lower in the FH population (35 % in men, 36 % in women) v. those non-affected (38 % in both sexes, P<0·005), due to the lower consumption of saturated fats (12·1 % in FH patients, 13·2 % in non-affected, P<0·005). Consumption of sugars was lower in FH patients v. non-affected relatives (P<0·05). Consumption of vegetables, fish and skimmed milk was higher in the FH population (P<0·005). Patients with FH showed greater adherence to a Mediterranean diet pattern v. non-affected relatives (P<0·005). Active smoking was lower and moderate physical activity was higher in people with FH, especially women (P<0·005).ConclusionsAdult patients with FH report healthier lifestyles than their non-affected family members. They eat a healthier diet, perform more physical activity and smoke less. However, this patient group's consumption of saturated fats and sugars still exceeds guidelines.
