Burden of an educational program on end of life management in a Internal Medicine ward: a real life report.

Background And Aim: Appropriate end of life (EOL) management in Internal Medicine wards is challanging. The aim of this study was to analyze the burden of an educational program on EOL management in a Internal Medicine ward. Materials and methods: We retrospectively analysed characteristics and management of patients consecutively died in an italian Internal Medicine ward along one year.

Rosuvastatin inhibits spontaneous and IL-1β-induced interleukin-6 production from human cultured osteoblastic cells.

Objective: Experimental and clinical data suggest that statins may protect bone by inhibiting bone resorption and/or stimulating bone formation. Interleukin-6 (IL-6) is produced by osteoblasts, and potently stimulates osteoclast activation playing a key role in normal bone resorption as well as in post-menopausal and inflammation-driven osteoporosis. Although statins inhibit IL-6 production from different cell types, currently no data exist on osteoblasts.

In vitro effects of VA441, a new selective cyclooxygenase-2 inhibitor, on human osteoarthritic chondrocytes exposed to IL-1β.

The aim of this in vitro study was to examine the possible effect of [2-methyl-5-(4-methylsulphonyl)phenyl-1-phenyl-3-(2-n-propyloxyethyl)]-1H-pyrrole (VA441), a new selective cyclooxygenase (COX)-2 inhibitor, on human osteoarthritic (OA) chondrocyte cultivated in the presence or absence of interleukin-1β (IL-1β). In particular, we assessed the effects of 1 and 10 μM of VA441, celecoxib, and indomethacin on cell viability, COX-2 and inducible nitric oxide synthase (iNOS) gene expression, prostaglandin E(2) (PGE(2)) production, and nitric oxide (NO) and metalloproteinase-3 (MMP-3) release. Furthermore, we carried out morphological assessment by transmission electron microscopy (TEM).

Fasitibant prevents the bradykinin and interleukin 1β synergism on prostaglandin E₂ release and cyclooxygenase 2 expression in human fibroblast-like synoviocytes.

This study investigates the effect of the selective and potent B(2) receptor antagonist fasitibant (MEN16132) on the proinflammatory effect of bradykinin (BK) and its interaction with interleukin 1β (IL-1β) in human synoviocytes. PGE(2) content was detected in the surnatants and COX-2 and COX-1 gene and protein expression determined in the cells. Radioligand binding ([(3) H]BK) and BK-induced inositolphosphate experiments were performed.

Raloxifene protects cultured human chondrocytes from IL-1β induced damage: a biochemical and morphological study.

It is well known that estrogens are implicated in the pathogenesis of osteoarthritis. Raloxifene is a selective estrogen receptor modulator used in the treatment of osteoporosis, though little is known about the possible effects of raloxifene on cartilage metabolism. The aim of our study was to evaluate the possible in vitro effects of raloxifene in human osteoarthritis chondrocytes cultivated in the presence or absence of Interleukin-1 beta (IL-1β) (5 ng/ml).

Biochemical investigation of the effects of human platelet releasates on human articular chondrocytes.

The aim of the present study was to demonstrate the mitogenic and differentiating properties of platelet-rich plasma releasates (PRPr) on human chondrocytes in mono- and three-dimensional cultures. In order to assess if PRPr supplementation could maintain the chondrocyte phenotype or at least inhibit the cell de-differentiation even after several days in culture, we performed a proteomic study on several cell cultures independently grown, for different periods of time, in culture medium with FCS, human serum (HS), and releasates obtained from PRP and platelet-poor plasma (PPP). We found that PRP treatment actually induced in chondrocytes the expression of proteins (some of which novel) involved in differentiation.

Inhibitory effect of synthetic cannabinoids on cytokine production in rheumatoid fibroblast-like synoviocytes.

Objective: To verify whether synthetic cannabinoids (CP55,940 and WIN55,212-2) are able to exert an anti-inflammatory effect on rheumatoid fibroblast-like synoviocytes (FLS) by down-regulating cytokine production, and determine whether this effect could be mediated by CB1/CB2 cannabinoid receptors.

Methods: Interleukin-6 (IL-6) and interleukin-8 (IL-8) were assayed in the supernatant from cultured FLS by ELISA method before and after 3 hours of incubation with CP55,940 (10 microM) and WIN55,212-2 (10 microM). Co-stimulation of cells with the cannabinoid receptor antagonists was performed to evaluate receptor involvement in cytokine modulation.

[Anabolic effects and inhibition of interleukin 6 production induced by neridronate on human osteoblasts].

Unlabelled: Bisphosphonates (BPs) are pharmacological compounds widely used in the treatment of a variety of bone-related diseases, particularly where the bone-turnover is skewed in favour of osteolysis. The mechanisms by which BPs reduce bone-resorption directly acting on osteoclasts (OCs) are now largely clarified even at molecular level. The researches concerning the BPs effects on osteoblasts (OBs) have instead shown variable results.

[Complete neurologic recovery after prolonged cardiac arrest caused by refractory ventricular fibrillation. Clinical case].

The clinical case of a 45-year-old patient referred to us for chest pain and with clinical examination and ECG negative for ischaemic damage, is reported. The patient, hospitalised in a bed without an ECG monitor, presented heart failure due to ventricular fibrillation. He was re-examined first with ventilation and EMC and then with defibrillation.
