Abstract
Abstract
Background
New onset atrial fibrillation (NOAF) is not a so rare condition among patients hospitalized for ST-segment elevation myocardial infarction (STEMI). Several studies showed that NOAF during an acute coronary syndrome (ACS) leads to increased mortality, both at short and long term. The indications for the treatment of patients with known AF undergoing percutaneous coronary interventions (PCI) are clear, while less is available about the management of NOAF during ACS and in particular during STEMI. The purpose of this study is therefore to evaluate mortality and clinical outcome of this high risk subgroup of patients.
Methods
We analysed 1455 consecutive patients undergoing coronary angiography and/or PCI for STEMI. CHA2DS2-VASc and HAS-BLED scores were calculated for all patients. In-hospital, 1-year and long-term follow up mortality was evaluated for all patients. Cerebral ischemic and hemorrhagic events were also evaluated as clinical endpoints at 1 year.
Results
NOAF was detected in 102 subjects, 62.7% males, with a mean age of 74.8±10.6 years. We found a high prevalence of main cardiovascular risk factors such as hypertension, dyslipidemia, smoke and renal failure. Mean ejection fraction (EF) was 43.5±12.1% and the mean atrial volume was increased (58±20.9 ml). The most represented type of MI at admission was anterior STEMI (46%). NOAF occurred mainly in the peri-acute phase and had a very variable duration (8.1±12.5 min). During hospitalization all patients were treated with Enoxaparin, but only 25.2% of them were discharged with long term oral anticoagulation (16.7% warfarin, 4.9% direct oral anticoagulant). The majority of patients had a CHA2DS2-VASc score >2 and a HAS-BLED score of 2 or 3. In-hospital mortality was 14.2%, while 1-year mortality was 17.2% and long term mortality 32.1% (median follow-up time 1820 days, range 341 to 3985). Through a logistic regression analysis we identified age as an independent predictor of mortality both at short and long term follow up, while EF was the only independent predictor for in-hospital mortality and arrhythmia duration for 1-year mortality. At 1-year follow up we recorded three ischemic strokes, while no bleeding complications.
Conclusions
STEMI patients who develop NOAF are a very high-risk population and are characterized by increased short and long term mortality. NOAF should be diagnosed and treated as soon as possible with a correct indication to long term OAC based on the ratio between ischemic and hemorrhagic risk.

Long term results of a phase II trial of hypofractionated adjuvant radiotherapy for early-stage breast cancer with volumetric modulated arc therapy and simultaneous integrated boost. Radiother Oncol 2021; 164:50-56. [PMID: 34537289 DOI: 10.1016/j.radonc.2021.09.006] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2021] [Revised: 09/01/2021] [Accepted: 09/09/2021] [Indexed: 11/28/2022]
Abstract
PURPOSE to report toxicity and cosmetic outcome with a median follow-up of 6 years of a phase II trial of hypofractionated radiotherapy with volumetric modulated arc therapy (VMAT) and simultaneous integrated boost (SIB) for early-stage breast cancer after conservative surgery. MATERIALS AND METHODS From August 2010 to September 2014, patients requiring adjuvant radiotherapy for early-stage breast cancer were treated according to a phase I-II protocol with SIB to 40.5 and 48 Gy to the breast and the boost region, respectively, with VMAT technique. The primary endpoint evaluated the treatment feasibility regarding adherence to required dose constraints for target, heart and lungs. Acute and late toxicity, local and distant control were secondary endpoints. RESULTS 450 patients were included in the trial and analysed after a median follow-up of 6 years. Acute toxicity was already presented in a previous paper. Regarding late toxicity, 93% of patients had no skin alteration at five years, while 5.3% and 1.3% did record G1 and G2 residual toxicity, respectively. Cosmetic outcome was scored good or excellent in almost all cases (97.2%), fair only in 2.3% of patients. Residual tenderness in the irradiated breast was reported by 10% of patients. Cosmesis and breast pain improved during follow-up. Two cases of G2 pneumonitis and two cases of ischemic cardiopathy were registered during follow-up. Five cases presented local recurrence in the homolateral breast, four patients had a new primary cancer in the contralateral breast, while distant metastasis developed in 7 patients. CONCLUSION After more than six years, hypofractionated VMAT with SIB for adjuvant radiotherapy in early-stage breast cancer patients remains a safe and effective approach. Mature data on skin toxicity and cosmetic outcome are encouraging. However, longer follow-up is required to evaluate local control, cardiac toxicity and secondary carcinogenesis.

Long-term outcomes after pancreatoduodenectomy for ampullary cancer: The influence of the histological subtypes and comparison with the other periampullary neoplasms. Pancreatology 2021; 21:950-956. [PMID: 33795194 DOI: 10.1016/j.pan.2021.03.005] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/15/2020] [Revised: 03/08/2021] [Accepted: 03/11/2021] [Indexed: 02/08/2023]
Abstract
BACKGROUND Ampullary carcinoma (AC) is histologically classified as intestinal (In-AC), pancreaticobiliary (Pb-AC) or mixed-AC. The prognostic role of AC subtypes has been debated and remains unclear. The aims of this study were to evaluate outcomes after pancreatoduodenectomy (PD) for each subtype of AC and to compare these with pancreatic ductal adenocarcinoma [PDAC] and distal cholangiocarcinoma [DCC]. METHODS PDs performed for AC between 2010 and 2018 were retrospectively evaluated. Histological subtype was obtained for all patients. One-year, 3-year and 5-year disease-free-survival (DFS) and overall survival (OS) rates were calculated. Kaplan-Meier survival analysis was performed to compare Pb-AC, In-AC and mixed-AC. Comparison with PDs performed for PDAC and DCC during the same period was also performed. RESULTS A total of 97 patients undergoing PD for AC were evaluated: 34 (35.1%) In-AC, 54 (55.7%) Pb-AC and 9 mixed-AC (9.3%). DFS and OS rates for Pb-AC were significantly lower compared to In-AC (p < 0.05 and p < 0.01), but similar to mixed-AC (p = 0.3 and p = 0.4). Adjuvant therapy was not associated with increased survival, regardless of the histological subtype (p > 0.05). During the same period, 337 and 53 PDs for PDAC and DCC, respectively, were performed. In-AC was associated with significantly better outcomes compared to PDAC and DCC (p < 0.001); DFS and OS rates for Pb-AC and mixed AC were significantly higher compared to PDAC (p < 0.001), but similar to DCC (p > 0.05). CONCLUSIONS Pb-AC has significantly worse survival compared to In-AC. Moreover, mixed-AC should be considered as Pb-AC. Pb-AC and mixed-AC seem to have better prognosis compared to PDAC, but similar to DCC.

Abstract
BACKGROUND Unintentional carbon monoxide (CO) poisoning poses a public health challenge. The UK National Poisons Information Service (NPIS) provides advice to healthcare professionals via the online database, TOXBASE®, and a 24-hour telephone line. Our aim was to analyse all CO-related enquiries to the NPIS. METHODS We analysed enquiries regarding unintentional CO exposure (1st July 2015-30th June 2019). Information on patient demographics, CO source and location, clinical features and poisoning severity was collected from telephone enquiries and TOXBASE accesses. RESULTS 2970 unintentional non-fire-related CO exposures were reported. Exposures occurred commonly in the home (60%) with faulty boilers frequently implicated (27.4%). Although five fatalities were reported, 68.7% of patients experienced no or minor symptoms only (headache most frequently reported). Despite being the gold standard measurement, blood carboxyhaemoglobin concentration was only recorded in 25.6% patients, with no statistically significant correlation with severity. CONCLUSIONS Unintentional CO exposures in the UK commonly occur in domestic settings and although are generally of low severity, fatalities continue to occur. Carboxyhaemoglobin measurement is important to confirm exposure but further work is required to assess its validity as a prognostic indicator in CO exposure. Public health policy should continue to focus on raising awareness of the dangers of CO.

How to manage thromboembolic risk in patient with SARS-CoV-2-related disease in the Emergency Department: A case report of cardiogenic shock due to massive pulmonary embolism. Respir Med Case Rep 2020; 31:101185.

Abstract
BACKGROUND Although the most known feature of SARS-CoV-2 associated infection is a mild to severe pneumonia, increasing evidence suggests the existence of an infection-associated risk of both arterial and venous thromboembolism (VTE), but the exact magnitude of this phenomenon is still unknown.Given that, it is important for the Emergency Physician to remember that a SARS-CoV-2 associated respiratory failure can be caused not only by the pulmonary parenchymal inflammation that characterizes the pneumonia, but also by an associated pulmonary thromboembolism. CASE REPORT A healthy 73-years old woman admitted to the ED for dyspnea, fever and thoracic pain. Cardiac ultrasound, electrocardiogram and clinical findings suggested a diagnosis of cardiogenic obstructive shock due to acute pulmonary embolism, successfully treated with thrombolysis. A CT angiography confirmed the pulmonary embolism (EP) diagnosis and showed bilateral pneumonia, caused by SARS-CoV-2 infection. CONCLUSION Considering the high prevalence of thromboembolic events in COVID-19 patients it is mandatory for the emergency physician to systematically evaluate signs of pulmonary thromboembolism, in order to perform the most patient-tailored therapy as soon as possible.

Pharmacological effects of vinorelbine in combination with lenvatinib in anaplastic thyroid cancer. Pharmacol Res 2020; 158:104920.

Abstract
Anaplastic thyroid cancer (ATC) is a rare neoplasia with a poor prognosis. Proliferation and apoptosis assays were performed on ATC cell lines (8305C, 8505C) exposed to vinorelbine, lenvatinib, as well as to concomitant combinations. ABCB1, ABCG2 and CSF-1 mRNA expression was evaluated by real time PCR. The relative levels of pospho Akt were investigated as part of a human phospho-kinase array analysis, and CSF-1 and VEGFR-2 protein levels were measured by ELISA. The intracellular concentration of lenvatinib in ATC cells was measured by combined reversed-phase liquid chromatography-tandem mass spectrometry. An ATC subcutaneous xenograft tumor model in nude mice was treated with vinorelbine, lenvatinib, or vinorelbine plus lenvatinib. After treatment with vinorelbine, lenvatinib, a significant antiproliferative effect in ATC cell lines was observed. The concomitant treatment of vinorelbine and lenvatinib revealed synergism for all the fractions of affected cells. A decrease in ABCB1 expression was reported in both ATC cell lines treated with the lenvatinib plus vinorelbine combination, as was an increase in the intracellular concentration of lenvatinib. The combination caused a decrease in Akt, GSK3α/β, PRAS40 and Src phosphorylation, and in both CSF-1 mRNA and protein levels. In the subcutaneous tumor model, the combination reduced the tumor volume during the treatment period. Our results establish the synergistic ATC antitumor activity of a vinorelbine and lenvatinib combination.

Abstract
Anaplastic thyroid cancer (ATC) is the most aggressive form of thyroid cancer, and novel combined therapies are urgently needed to prolong patient survival. No data are currently available on the preclinical activity of the combination of linifanib, a CSF-1R inhibitor, and irinotecan in ATC. The aim of the study was to evaluate the in vitro and in vivo activity of linifanib plus irinotecan. Proliferation and apoptosis assays were performed on 8305C and 8505C human ATC cell lines exposed to SN-38, the active metabolite of irinotecan, linifanib alone, and their concomitant combination. Synergism was evaluated by the combination index method. Quantification of pospho-CSF-1R levels was performed by ELISA. In vivo ATC orthotopic xenografts were treated with the single drugs, or their combination, to evaluate their impact on survival. Histology and immunohistochemistry were performed on ATC tissue samples. Both SN-38 and linifanib inhibited in vitro the proliferation of 8305C and 8505C cells in a concentration-dependent manner, whereas their concomitant treatment revealed a strong synergism in the ATC cells. A significant pro-apoptotic activity was found in both ATC cell lines treated with linifanib alone and in combination with SN-38. Moreover, linifanib significantly decreased the levels of phospho-CSF-1R after 24 h and 72 h in both 8505C and 8305C cells, and this was also observed with the concomitant administration of SN-38. In vivo, the combination of linifanib and irinotecan produced a greater survival result than either monotherapy, and resulted in a significant higher median survival. In some of the mice the combination produced a complete response with a macroscopic disappearance of the disease, as confirmed by histology. In conclusion, the synergistic ATC antitumor activity of linifanib/irinotecan combination significantly increased the survival of ATC affected mice and induced some complete responses, suggesting a potential role of this schedule in ATC patient's treatment.

Abstract
The Comparative Psychotherapy Process Scale (CPPS) is an instrument designed to measure therapist interventions in a psychotherapy session. The scale includes 20 items divided into two subscales: the PI (psychodynamic-interpersonal) scale, which describes psychodynamic-interpersonal techniques; and the CB (cognitive-behavioural) scale, which includes cognitive-behavioural interventions. The aim of the study was to examine the psychometric properties of the CPPS, comparing the PI and CB subscales with the psychodynamic, cognitive and STTP prototypes, as described by the Psychotherapy Process Q-set(PQS). The sample comprised 94 sessions (N = 94) of psychodynamic and cognitive-behavioural orientation. Two groups of independent raters with excellent interrater reliability (ICC = .78) evaluated the sessions. The results suggest that the CPPS is a valid and reliable instrument that provides a clinically sensitive and psychometrically robust evaluation of a therapist's techniques. The clinical and research implications of the results are discussed.

Abstract
The purpose of this study was to examine pazopanib/topotecan combination activity vs. pazopanib monotherapy on anaplastic thyroid cancer (ATC) cells. Proliferation analyses were performed on ATC cell lines administered for 72 h with pazopanib and topotecan alone and to their simultaneous combination. Pazopanib and topotecan produced a strong synergism on ATC cells, calculated by the combination index, increasing the intracellular concentrations of topotecan lactone measured by high-performance liquid chromatography. Furthermore, a significantly decrease of the gene expression of ATP-binding cassette transporter G2 (ABCG-2), vascular endothelial growth factor (VEGF), hypoxia-inducible factor-1α (HIF-1α), and colony stimulating factor-1 (CSF-1) was presented in combination-treated ATC cells by real time PCR tests. In summary, the simultaneous association of pazopanib and topotecan established a highly synergistic ATC antiproliferative effect, suggesting a new possibility to translate this schedule into clinical trials.

Abstract
OBJECTIVES Nonsteroidal anti-inflammatory drugs can exert detrimental effects in the lower digestive tract. The aim of this study was to examine the protective effects of a combination of the probiotic Bifidobacterium longum BB536 (Bifidobacterium) with the prebiotic lactoferrin in a rat model of diclofenac-induced enteropathy. METHODS Enteropathy was induced in 40-wk-old male rats by intragastric diclofenac (4 mg/kg twice daily for 14 d). Lactoferrin (100 mg/kg twice daily), Bifidobacterium (2.5 × 106 CFU/rat twice daily) or their combination were administered 1 h before diclofenac. At the end of treatments, the ileum was processed for the evaluation of histologic damage, myeloperoxidase (MPO) and malondialdehyde (MDA) levels, as well as the expression of Toll-like receptors 2 and 4 (TLR-2/-4) and the activation of downstream signaling molecules (MyD88 and nuclear factor [NF]-κB p65). Blood hemoglobin and fecal calprotectin were also assessed. RESULTS Diclofenac induced intestinal damage, along with increments of MPO and MDA, overexpression of TLR-2, TLR-4, MyD88, and NF-κB p65, increased fecal calprotectin and decreased blood hemoglobin levels. Lactoferrin or Bifidobacterium alone prevented diclofenac-induced enteric damage, and the changes in blood hemoglobin, MPO, MDA, fecal calprotectin, and NF-κB p65. Bifidobacterium, but not lactoferrin, decreased TLR-4 expression, although none of them affected MyD88 overexpression. TLR-2 expression was slightly enhanced by all treatments. The combined administration of lactoferrin and Bifidobacterium reduced further the intestinal damage, and restored MPO and blood hemoglobin levels. CONCLUSIONS Diclofenac induced ileal mucosal lesions by activation of inflammatory and pro-oxidant mechanisms. These detrimental actions were prevented by the combination of lactoferrin with Bifidobacterium likely through the modulation of TLR-2/-4/NF-κB proinflammatory pathways.

Abstract
The aim of the study was to evaluate the effects and the related pharmacological mechanisms of switched schedules of antiangiogenic and chemotherapeutic drugs beyond progression after a first-line treatment in a colorectal cancer preclinical model. In vivo studies were performed in nude mice subcutaneously transplanted with colon cancer cells. The treatments included drug combinations with a switch between chemotherapeutic (i.e., irinotecan and 5-fluorouracil) and/or antiangiogenic drugs (i.e., anti-VEGF antibodies and sunitinib) at the time of tumor progression. Proliferation assays were also achieved in vitro on different colon cancer cell lines exposed to SN-38 and sunitinib alone or in combination. ABCG2 gene expression was performed with real-time PCR and SN-38 intracellular concentrations were measured. The switch in the combined treatments, at the time of tumor progression, of the chemotherapeutic (from irinotecan to 5-fluoruracil), or the antiangiogenic drug (from anti-VEGF antibodies to sunitinib) or of both drugs induced a new response. Immunohistochemistry of stromal PDGF-C, PlGF, SD1-α, Tie-2, and VEGFR-2 showed statistical differences between tumors at the time of relapse and after the switched therapy. Moreover, the combination of SN-38 and sunitinib caused synergism on colon cancer cells, with significant inhibition of the ABCG2 gene expression and an increase of SN-38 intracellular concentrations. Our observations may be of clinical relevance, suggesting the switch of single chemotherapeutic or antiangiogenic drugs beyond progression of the disease to obtain a new tumor response due to a modulation of angiogenic factors and a direct effect on tumor cells with a possible variation of intracellular drug concentrations.

Non-steroidal anti-inflammatory drugs (NSAIDs) can damage the small intestine, mainly through an involvement of enteric bacteria. This study examined the pathophysiology of NSAID-associated intestinal lesions in a rat model of diclofenac-enteropathy and evaluated the effect of rifaximin on small bowel damage. Enteropathy was induced in 40-week old male rats by intragastric diclofenac (4 mg/kg BID, 14 days). Rifaximin (delayed release formulation) was administered (50 mg/kg BID) 1 h before the NSAID. At the end of treatments, parameters dealing with ileal damage, inflammation, barrier integrity, microbiota composition, and TLR-NF-κB-inflammasome pathway were evaluated. In addition, the modulating effect of rifaximin on NLRP3 inflammasome was tested in an in vitro cell system. Diclofenac induced intestinal damage and inflammation, triggering an increase in tissue concentrations of tumor necrosis factor and interleukin-1β, higher expression of TLR-2 and TLR-4, MyD88, NF-κB and activation of caspase-1. In addition, the NSAID decreased ileal occludin expression and provoked a shift of bacterial phyla toward an increase in Proteobacteria and Bacteroidetes abundance. All these changes were counterbalanced by rifaximin co-administration. This drug was also capable of increasing the proportion of Lactobacilli, a genus depleted by the NSAID. In LPS-primed THP-1 cells stimulated by nigericin (a model to study the NLRP3 inflammasome), rifaximin reduced IL-1β production in a concentration-dependent fashion, this effect being associated with inhibition of the up-stream caspase-1 activation. In conclusion, diclofenac induced ileal mucosal lesions, driving inflammatory pathways and microbiota changes. In conclusion, rifaximin prevents diclofenac-induced enteropathy through both anti-bacterial and anti-inflammatory activities.

Abstract
Purpose: Luteolin exerts beneficial effects against obesity-associated comorbidities, although its influence on vascular dysfunction remains undetermined. We examined the effects of luteolin on endothelial dysfunction in a mouse model of diet-induced obesity. Methods: Standard diet (SD) or high-fat diet (HFD)-fed mice were treated daily with luteolin intragastrically. After 8 weeks, body and epididymal fat weight, as well as blood cholesterol, glucose, and triglycerides were evaluated. Endothelium-dependent relaxations of resistance mesenteric vessels was assessed by a concentration-response curve to acetylcholine, repeated upon Nw-nitro-L-arginine methylester (L-NAME) or ascorbic acid infusion to investigate the influence of nitric oxide (NO) availability and reactive oxygen species (ROS) on endothelial function, respectively. Intravascular ROS production and TNF levels were measured by dihydroethidium dye and ELISA, respectively. Endothelial NO synthase (eNOS) and superoxide dismutase 1 (SOD1), as well as microRNA-214-3p expression were examined by Western blot and RT-PCR assays, respectively. Results: HFD animals displayed elevated body weight, epididymal fat weight and metabolic indexes. Endothelium-dependent relaxation was resistant to L-NAME and enhanced by ascorbic acid, which restored also the inhibitory effect of L-NAME, suggesting a ROS-dependent reduction of NO availability in HFD vessels. Moreover, media-lumen ratio, intravascular superoxide anion and TNF levels were increased, while vascular eNOS, SOD1, and microRNA-214-3p expression were decreased. In HFD mice, luteolin counteracted the increase in body and epididymal fat weight, and metabolic alterations. Luteolin restored vascular endothelial NO availability, normalized the media-lumen ratio, decreased ROS and TNF levels, and normalized eNOS, SOD1 and microRNA-214-3p expression. Conclusion: Luteolin prevents systemic metabolic alterations and vascular dysfunction associated with obesity, likely through antioxidant and anti-inflammatory mechanisms.

Interplay between colonic inflammation and tachykininergic pathways in the onset of colonic dysmotility in a mouse model of diet-induced obesity. Int J Obes (Lond) 2018; 43:331-343. [PMID: 30082748 DOI: 10.1038/s41366-018-0166-2] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/02/2017] [Revised: 05/24/2018] [Accepted: 06/24/2018] [Indexed: 12/15/2022]
Abstract
BACKGROUND The murine model of high fat diet (HFD)-induced obesity is characterized by an increment of intestinal permeability, secondary to an impairment of mucosal epithelial barrier and enteric inflammation, followed by morphofunctional rearrangement of the enteric nervous system. The present study investigated the involvement of abdominal macrophages in the mechanisms underlying the development of enteric dysmotility associated with obesity. METHODS Wild type C57BL/6J mice were fed with HFD (60% kcal from fat) or normocaloric diet (NCD, 18% kcal from fat) for 8 weeks. Groups of mice fed with NCD or HFD were treated with clodronate encapsulated into liposomes to deplete abdominal macrophages. Tachykininergic contractions, elicited by electrical stimulation or exogenous substance P (SP), were recorded in vitro from longitudinal muscle colonic preparations. Substance P distribution was examined by confocal immunohistochemistry. The density of macrophages in the colonic wall was examined by immunohistochemical analysis. Malondialdehyde (MDA, colorimetric assay) and IL-1β (ELISA assay) levels were also evaluated. RESULTS MDA and IL-1β levels were increased in colonic tissues from HFD-treated animals. In colonic preparations, electrically evoked tachykininergic contractions were enhanced in HFD mice. Immunohistochemistry displayed an increase in substance P immunoreactivity in myenteric ganglia, as well as in the muscular layers of colonic cryosections from obese mice. Macrophage depletion in HFD mice was associated with a significant reduction of colonic inflammation. In addition, the decrease in macrophage density attenuated the morphofunctional alterations of tachykininergic pathways observed in obese mice. CONCLUSION Obesity elicited by HFD determines a condition of colonic inflammation, followed by a marked rearrangement of motor excitatory tachykininergic enteric nerves. Macrophage depletion counteracted the morphofunctional changes of colonic neuromuscular compartment, suggesting a critical role for these immune cells in the onset of enteric dysmotility associated with obesity.

Abstract
Obesity is a growing worldwide health problem, with an alarming increasing prevalence in developed countries, caused by a dysregulation of energy balance. Currently, no wholly successful pharmacological treatments are available for obesity and related adverse consequences. In recent years, hints obtained from several experimental animal models support the notion that purinergic signalling, acting through ATP-gated ion channels (P2X), G protein-coupled receptors (P2Y) and adenosine receptors (P1), is involved in obesity, both at peripheral and central levels. This review has drawn together, for the first time, the evidence for a promising, much needed novel therapeutic purinergic signalling approach for the treatment of obesity with a 'proof of concept' that hopefully could lead to further investigations and clinical trials for the management of obesity.

Abstract
Background and purpose Apigenin can exert beneficial actions in the prevention of obesity. However, its putative action on obesity-associated bowel motor dysfunctions is unknown. This study examined the effects of apigenin on colonic inflammatory and motor abnormalities in a mouse model of diet-induced obesity. Experimental approach Male C57BL/6J mice were fed with standard diet (SD) or high-fat diet (HFD). SD or HFD mice were treated with apigenin (10 mg/Kg/day). After 8 weeks, body and epididymal fat weight, as well as cholesterol, triglycerides and glucose levels were evaluated. Malondialdehyde (MDA), IL-1β and IL-6 levels, and let-7f expression were also examined. Colonic infiltration by eosinophils, as well as substance P (SP) and inducible nitric oxide synthase (iNOS) expressions were evaluated. Motor responses elicited under blockade of NOS and tachykininergic contractions were recorded in vitro from colonic longitudinal muscle preparations. Key results When compared to SD mice, HFD animals displayed increased body weight, epididymal fat weight and metabolic indexes. HFD mice showed increments in colonic MDA, IL-1β and IL-6 levels, as well as a decrease in let-7f expression in both colonic and epididymal tissues. HFD mice displayed an increase in colonic eosinophil infiltration. Immunohistochemistry revealed an increase in SP and iNOS expression in myenteric ganglia of HFD mice. In preparations from HFD mice, electrically evoked contractions upon NOS blockade or mediated by tachykininergic stimulation were enhanced. In HFD mice, Apigenin counteracted the increase in body and epididymal fat weight, as well as the alterations of metabolic indexes. Apigenin reduced also MDA, IL-1β and IL-6 colonic levels as well as eosinophil infiltration, SP and iNOS expression, along with a normalization of electrically evoked tachykininergic and nitrergic contractions. In addition, apigenin normalized let-7f expression in epididymal fat tissues, but not in colonic specimens. Conclusions and implications Apigenin prevents systemic metabolic alterations, counteracts enteric inflammation and normalizes colonic dysmotility associated with obesity.

Abstract
Objectives: Systemic sclerosis (SSc) is a connective tissue disorder presenting fibrosis of the skin and internal organs, for which no effective treatments are currently available. Increasing evidence indicates that the P2X7 receptor (P2X7R), a nucleotide-gated ionotropic channel primarily involved in the inflammatory response, may also have a key role in the development of tissue fibrosis in different body districts. This study was aimed at investigating P2X7R expression and function in promoting a fibrogenic phenotype in dermal fibroblasts from SSc patients, also analyzing putative underlying mechanistic pathways. Methods: Fibroblasts were isolated by skin biopsy from 9 SSc patients and 8 healthy controls. P2X7R expression, and function (cytosolic free Ca2+ fluxes, α-smooth muscle actin [α-SMA] expression, cell migration, and collagen release) were studied. Moreover, the role of cytokine (interleukin-1β, interleukin-6) and connective tissue growth factor (CTGF) production, and extracellular signal-regulated kinases (ERK) activation in mediating P2X7R-dependent pro-fibrotic effects in SSc fibroblasts was evaluated. Results: P2X7R expression and Ca2+ permeability induced by the selective P2X7R agonist 2'-3'-O-(4-benzoylbenzoyl)ATP (BzATP) were markedly higher in SSc than control fibroblasts. Moreover, increased αSMA expression, cell migration, CTGF, and collagen release were observed in lipopolysaccharides-primed SSc fibroblasts after BzATP stimulation. While P2X7-induced cytokine changes did not affect collagen production, it was completely abrogated by inhibition of the ERK pathway. Conclusion: In SSc fibroblasts, P2X7R is overexpressed and its stimulation induces Ca2+-signaling activation and a fibrogenic phenotype characterized by increased migration and collagen production. These data point to the P2X7R as a potential, novel therapeutic target for controlling exaggerated collagen deposition and tissue fibrosis in patients with SSc.

Abstract
Adenosine A2B receptors (A2BR) regulate several enteric functions. However, their implication in the pathophysiology of intestinal dysmotility associated with high-fat diet (HFD)-induced obesity has not been elucidated. We investigated the expression of A2BR in mouse colon and their role in the mechanisms underlying the development of enteric dysmotility associated with obesity. Wild-type C57BL/6J mice were fed with HFD (60% kcal from fat) or normocaloric diet (NCD; 18% kcal from fat) for 8 weeks. Colonic A2BR localization was examined by immunofluorescence. The role of A2BR in the control of colonic motility was examined in functional experiments on longitudinal muscle preparations (LMPs). In NCD mice, A2BR were predominantly located in myenteric neurons; in HFD animals, their expression increased throughout the neuromuscular layer. Functionally, the A2BR antagonist MRS1754 enhanced electrically induced NK1-mediated tachykininergic contractions in LMPs from HFD mice, while it was less effective in tissues from NCD mice. The A2B receptor agonist BAY 60-6583 decreased colonic tachykininergic contractions in LMPs, with higher efficacy in preparations from obese mice. Both A2BR ligands did not affect contractions elicited by exogenous substance P. Obesity is related with a condition of colonic inflammation, leading to an increase of A2BR expression. A2BR, modulating the activity of excitatory tachykininergic nerves, participate to the enteric dysmotility associated with obesity.

Abstract
This study used naturalistic data from psychodynamic (PD) and cognitive-behavioral (CB) clinicians in the community to offer a portrait of treatments for eating disorder (ED) patients as provided in everyday clinical practice. The research aims were (1) to examine the therapeutic interventions reported by PD and CB clinicians working with ED patients; and (2) to assess the impact of different variables (such as patient personality styles, ED symptomatology, and therapists' theoretical orientation and experience) on the technique use reported by clinicians. A national sample of PD and CB clinicians (N = 105) completed the Shedler-Westen Assessment Procedure-200 (SWAP-200; Westen & Shedler, 1999a, 1999b) to assess personality disorders of a female patient with EDs in their care, as well as the Comparative Psychotherapy Process Scale-Bulimia Nervosa (CPPS-BN; Thompson-Brenner & Westen, 2005) to describe the characteristic interventions used in their treatments. Results showed that PD clinicians tended to use primarily PD interventions, while CB clinicians employed CB techniques supplementing them with a wider range of PD strategies. However, clinicians from both theoretical orientations used adjunctive treatment techniques for EDs at a similar level. In addition, use of PD interventions was strongly associated with the personality styles of ED patients regardless of therapists' orientation, primarily being used more often when patients exhibited dysregulated and impulsive styles. Conversely, use of CB interventions was primarily related to a clinicians' CB orientation, patients with more explicit symptoms of anorexia nervosa, and negatively related to clinicians' years of experience. The clinical implications of these findings were discussed. (PsycINFO Database Record

Abstract
Many previous studies have demonstrated that P2X(7) receptors (P2X(7)Rs) have a pleiotropic function in different pathological conditions and could represent a novel target for the treatment of a range of diseases. In particular, recent studies have explored the role of P2X(7)R in fibrosis, the pathological outcome of most chronic inflammatory diseases. The aim of this review is to discuss the biological features of P2X(7)R and summarize the current knowledge about the putative role of the P2X(7)R in triggering fibrosis in a wide spectrum of organs such as the lung, kidney, liver, pancreas, and heart.

Antiarrhythmic potential of anticytokine therapy in rheumatoid arthritis: tocilizumab reduces corrected QT interval by controlling systemic inflammation. Arthritis Care Res (Hoboken) 2015; 67:332-9.

Abstract
OBJECTIVE Patients with rheumatoid arthritis (RA) are twice as likely to experience sudden cardiac death compared with individuals without RA. Although the underlying mechanisms of this have not been clarified, evidence points to the effects of systemic inflammation on ventricular repolarization. Accordingly, prolongation of the corrected QT (QTc) interval is more frequent in patients with RA compared with individuals without RA also correlating with C-reactive protein (CRP) and predicting all-cause mortality. Tocilizumab (TCZ) is an anti-interleukin-6 receptor antibody that potently inhibits inflammatory activation in RA, with rapid normalization of acute-phase reactant levels, including the CRP level. Therefore, we hypothesized that TCZ may normalize the QTc interval by dampening systemic inflammation, thus reducing the risk of arrhythmia in patients with RA. METHODS Seventeen consecutive patients with active RA who were scheduled to receive TCZ once every 4 weeks underwent a clinical examination, electrocardiography, and blood sampling just before the first injection with TCZ and again after 3 months and 6 months of treatment. RESULTS At baseline, 76% of patients displayed prolongation of the QTc interval (mean ± SD 452.3 ± 35.8 msec). TCZ treatment was associated with a rapid and significant reduction of the QTc interval to mean values <440 msec (up to 428.1 ± 34.3 msec). Throughout the study, QTc interval shortening correlated with decreases in both the CRP level, and more strongly, with circulating tumor necrosis factor α level. CONCLUSION These data provide further evidence of the close link between the degree of systemic inflammation and QTc interval duration in RA and also suggest an anti-arrhythmic potential for TCZ treatment, which may have a beneficial impact on the mortality of these patients.

Abstract
Home care customer satisfaction has been, until now, rarely evaluated. After illustrating the main italian regional surveys on this issue, the article presents a customer satisfaction survey carried out in the district of Civitavecchia (Local Health Unit 'Rome F'), Lazio, regarding 30 home care beneficiaries. Methodological aspects emerging from the survey are basically focused on: advantages and disadvantages of quantitative and qualitative approaches (possibly associated each other); main criteria of eligibility of people selected for interviewing, both patients or caregivers; conditions that maximize answers reliability, including training on interviewers. Authors highlight opportunity of using such kind of survey, integrated with other different tools, into a systemic vision, for promoting management changes coming from suggested problems, aimed at total quality management.

Abstract
OBJECTIVE The purpose of this study was to examine the utility of pedometer-based physical activity recommendations in predicting childhood adiposity. DESIGN Subjects (n=608) (9.6 years) were from two Midwestern USA communities. Physical activity was assessed by a pedometer. The percentage of subjects meeting physical activity recommendations was determined using published recommendations. Overweight and obesity were determined based on reference values for the body mass index (BMI) developed by the International Obesity Task Force. An elevated waist circumference (WC) was determined based on age- and sex-specific reference values >75th percentile. RESULTS Children who did not meet the pedometer recommendations were about two times more likely to be overweight/obese and have an elevated WC compared with those meeting recommendations. The BMI and WC were significantly different across pedometer step count groups in males and females. CONCLUSION Subjects not meeting the recommendations for steps per day were more likely to be classified with the overweight phenotype than those meeting the recommendation. A dose-response relationship between pedometer steps per day and adiposity is also apparent.

Abstract
AIM The extent to which orthodontic appliances can cause contact allergies due to nickel release is a controversial matter. Since the data provided by literature are contrasting, the Authors think that it is important to analyse nickel ions released in organic tissues by means of a plasma spectrometer. METHODS About 100 intact hairs were taken from 15 patients wearing fixed orthodontic appliances. The hairs had been washed 12 to 24 h before, in order to limit environmental contamination. The same procedure was carried out on a control group corresponding in sex, age and abode. The samples of hair were taken from at least 3 different scalp sites: frontal, vertex and occipital areas. RESULTS According to the spectrophotometric analysis of the hair, there were no differences in nickel concentrations between the test group (0.50 mg/g on average) and control group (0.64 mg/g) (*P<0.005). The mean value was reduced even further if minimum and maximum values were excluded (test group 0.46 mg/g, control group 0.52 mg/g). Even though there was a slight difference (0.14 mg/g), it showed that more nickel concentration was found in the control sample (without orthodontic appliances) to a maximum of 2.20 mg/g. This suggests that environmental contamination, in particular diet, has an influence on ion concentration. Other studies also confirm that gut absorption of nickel released in the mouth by orthodontic appliances is much lower than the absorption of nickel release through diet. CONCLUSIONS It can be assumed that orthodontic appliances do not release significant values of nickel to be a risk factor to the patient's health.

Abstract
INTRODUCTION Medical records have an important role in the communication among different care providers and in forensic medicine. In Italy, information on completeness and correctness of medical records is scanty, whereas future hospital accreditation could take into account their quality as a proxy of good medical practice. PURPOSE We performed a retrospective study in order to assess the quality of medical records in the Lazio region. METHODS From all 37009 hospital discharges for five different diseases in 123 hospitals (acute myocardial infarction (AMI), coronary artery bypass surgery, pneumonia, cerebrovascular disorders, breast surgery), registered in the Regional Hospital Information System, we selected a random sample of 2022 (5.5% of the total). Ten physicians, previously trained, reviewed the relative medical charts and filled in "ad hoc" questionnaires. RESULTS A total of 1960 (97% of the target) charts were reviewed. Organization and structure of data recording strongly varied. Important differences were found across the diseases for various items: presence of anamnesis 98.1% (range: from 95.6% for breast surgery to 100% for AMI); presence of physical examination 92.7% (range: from 88.1% for breast surgery to 98.5% for AMI), completeness of the daily medical records was good in 70.8% (range: from 34.2% for pneumonia to 93.9% for cerebrovascular disorders). Variability among different type of hospitals was also observed, being teaching hospitals and some private hospitals more accurate. CONCLUSIONS Quality of medical records tended to vary across different type of hospitals and different diseases. Actions for improving the quality should be undertaken as a priority. Efforts have to be done in restructuring charts, creating guidelines and training caregivers. The development and application of computer based health information systems should help solving these problems.

Abstract
BACKGROUND Inflammation plays an important role in the pathogenesis of bronchopulmonary dysplasia (BPD), but the exact nature of this inflammatory process is incompletely understood. Older infants with established BPD have higher levels of urinary leukotriene E(4) (LTE(4)) compared to healthy infants of the same age. This suggests that cysteinyl leukotrienes may play a role in the abnormalities seen in BPD. OBJECTIVES To measure urinary LTE(4) levels during the first month of life in premature infants, and to determine whether there are significant differences in premature infants who develop BPD, as compared to those who do not develop BPD. DESIGN Prospective, blinded, controlled study. SETTING Neonatal ICUs of a tertiary-care university hospital. METHODS Thirty-seven premature infants (< 33 weeks of gestational age) were enrolled prospectively at birth. Urinary LTE(4) levels were measured blinded, using a standard radioimmunoassay technique at 2 days, 7 days, and 28 days of life. At 1 month of age, infants were classified as with or without BPD, based on need for supplemental oxygen, and characteristic chest radiographs. Clinical features and urinary LTE(4) were compared between the two groups. RESULTS Mean +/- SD gestational age was 29 +/- 2.6 weeks. None of the infants had a family history of asthma. Thirteen of 37 infants were classified as having BPD at 28 days after birth. Mean gestational age in infants who developed BPD was 27 +/- 2.4 weeks, compared to 30 +/- 2 weeks in infants who did not develop BPD (p < 0.05). In infants with BPD, mean urinary LTE(4) levels of urinary creatinine were 1,762 +/- 2,003 pg/mg, 1,236 +/- 992 pg/mg, and 5,541 +/- 5,146 pg/mg at days 2, 7, and 28, respectively, compared to 1,304 +/- 1,195 pg/mg, 1,158 +/- 1,133 pg/mg, and 2,800 +/- 2,080 pg/mg in infants without BPD. LTE(4) levels at 2 days, 7 days, and 28 days did not correlate with the subsequent development of BPD. LTE(4) levels at day 28 were significantly higher than LTE(4) levels at day 2 and day 7 in both groups, even after correcting for gestational age or birth weight (p < 0.05). There was significant inverse correlation between LTE(4) levels at day 2 with gestational age and birth weight (p < 0.05). All 13 infants with BPD received steroid pulses, compared to 3 of 26 infants without BPD. Gestational age and use of postnatal steroid pulses, diuretics, and theophylline (for apnea of prematurity) were significantly associated with each other and with the subsequent development of BPD. CONCLUSION Urinary LTE(4) levels measured on the second day of life in very-low-birth-weight infants inversely correlate with gestational age and birth weight. Urinary LTE(4) levels may reflect lung injury and/or inflammation in premature infants, not necessarily related to BPD as it is presently defined.
