Unlabelled: Limited information is available on clinical characteristics and outcomes in very old patients with unprotected left main coronary artery disease (ULMCA) undergoing percutaneous coronary intervention (PCI).
Methods: From January 2004 and December 2008, 248 patients with ULMCA stenosis underwent coronary revascularization with stent implantation. Among those, 6 were older than 90 years at the time of the procedure and were included in this study.
Results: There were 5 males and 1 female; mean age was 91.5 years (range 91-93). All the patients presented with acute coronary syndromes. All of them had multivessel disease with a distal left main stenosis in 4 patients. All were deemed inoperable, with a mean EuroSCORE of 12.66 (range 10-20) and a predicted mortality at 34% (range15.8-86.6%). 5 patients received bare-metal stents and 1 patient a paclitaxel-eluting stent. Rotational atherectomy was required in 2 patients. Provisional side branch T-stenting with final kissing balloons was the technique used in all bifurcation lesions. Angiographic success was obtained in all patients. There were no in-hospital deaths or complications. After a 29.8-month (range 8-59) mean follow up period, a myocardial infarction caused by late stent thrombosis occurred in 1 patient and ischemia-driven target vessel revisualization was required in another; however, all patients were alive.
Conclusion: In the very elderly patients at excessively high risk for surgery, PCI for ULMCA disease is a suitable alternative with excellent short-term results and acceptable long-term outcomes.

Propolis mouthwashes efficacy in managing gingivitis and periodontitis: a systematic review of the latest findings.

Department of Orthodontics, Institute of Dentistry, Medical Faculty, Jagiellonian University, Kraków, Poland.
Background And Objectives: Gingivitis and periodontitis are common periodontal diseases that can significantly harm overall oral health, affecting the teeth and their supporting tissues, along with the surrounding anatomical structures, and if left untreated, leading to the total destruction of the alveolar bone and the connective tissues, tooth loss, and other more serious systemic health issues. Numerous studies have shown that propolis can help reduce gum inflammation, inhibit the growth of pathogenic bacteria, and promote tissue regeneration, but with varying degrees of success reported. For this reason, this comprehensive systematic review aims at finding out the truth concerning the efficacy of propolis mouthwashes in treating gingivitis and periodontitis, as its main objective.

Background: The benefit of mechanical circulatory support (MCS) with Impella (Abiomed, Inc, Danvers, MA) for patients undergoing non-emergent, high-risk percutaneous coronary intervention (HR-PCI) is unclear and currently the subject of a large randomized clinical trial (RCT), PROTECT IV. While contemporary registry data from PROTECT III demonstrated improvement of outcomes with Impella when compared with historical data (PROTECT II), there is lack of direct comparison to the HR-PCI cohort that did not receive Impella support.
Methods: We retrospectively identified patients from our institution meeting PROTECT III inclusion criteria (left ventricular ejection fraction [LVEF] <35% with unprotected left main or last remaining vessel or LVEF <30% undergoing multivessel PCI), and compared this group (NonIMP) to the published outcomes data from the PROTECT III registry (IMP).

Osteoporosis is the most common bone metabolic unbalance, leading to fragility fractures, which are known to be associated with structural changes in the bone. Cortical bone accounts for 80 % of the skeleton mass and undergoes remodeling throughout life, leading to changes in its thickness and microstructure. Although many studies quantified the different cortical bone structures using CT techniques (3D), they are often realised on a small number of samples.

Retrieving words quickly and correctly is an important language competence. Semantic contexts, such as prior naming of categorically related objects, can induce conceptual priming but also lexical-semantic interference, the latter likely due to enhanced competition during lexical selection. In the continuous naming (CN) paradigm, such semantic interference is evident in a linear increase in naming latency with each additional member of a category out of a seemingly random sequence of pictures being named (cumulative semantic interference/CSI effect).

In radio frequency identification (RFID), differences in spectrum policies and tag misreading in different countries are the two main issues that limit its application. To solve these problems, this article proposes a composite right/left-handed transmission line (CRLH-TL)-based reconfigurable antenna for ultra-high frequency near-field and far-field RFID reader applications. The CRLH-TL is achieved using a periodically capacitive gap-loaded parallel plate line.
