Abstract
OBJECTIVE To examine the relationship between sense of coherence (SOC) and physical health-related quality of life in patients with chronic illnesses by focusing on the mediating role of the mental component of quality of life. DESIGN Cross-sectional survey design. SETTING Secondary care; three departments of an Italian university hospital. METHODS The participants (n=209) in the study were adult (≥18 years) outpatients with a chronic pathology (eg, diabetes, thyroid disorders or cancer) at any phase in the care trajectory (eg, pre-treatment, undergoing treatment, follow-up care). They agreed to participate in the study after providing their informed consent. Data were collected using a structured self-reporting questionnaire. Data analysis was carried out using SPSS, and mediation analysis was performed via PROCESS macro. RESULTS The SOC score of the study sample was equivalent to that of the general population (mean difference=-2.50, 95% CI -4.57 to 0.00). Correlation analysis showed that SOC was mainly correlated to the mental component (MCS) (r=0.51, p<0.01) of quality of life and then to the physical component (PCS) (r=0.35, p<0.01). Mediation analysis showed that SOC was directly related to MCS (p<0.001, 95% CI 0.62 to 0.99) but not to PCS (p=0.42, 95% CI -0.27 to 0.12). In turn, MCS was directly related to PCS (p<0.001, 95% CI 0.76 to 1.01). The indirect effect of SOC on PCS through MCS was significant (0.71, p<0.001, bootstrap 95% CI 0.54 to 0.91), thus supporting the mediating role of the mental component of quality of life. CONCLUSION The indirect effect suggests that SOC is a marker of quality of life, especially of the mental component. The findings show that SOC is a psychological process that impacts patients' mental health status, which in turn affects physical health. Better knowledge of a person's SOC and how it affects his/her quality of life may help to plan tailoring interventions to strengthen SOC and improve health-related quality of life.

Abstract
BACKGROUND In Australia, Hepatitis C Virus (HCV) treatment is declining, despite broad access to direct-acting antiviral medication. People who inject drugs are proportionally over-represented in emergency department presentations. Emergency department assessment of people who have injected drugs for HCV presents an opportunity to engage this marginalised population with treatment. We describe the outcomes of risk-based screening and point-of-care anti-HCV testing for emergency department patients, and linkage to outpatient antiviral treatment. METHODS During the three-month study period, consecutive adult patients who presented to the emergency department during the study times were screened for risk factors and offered the OraQuick oral HCV antibody test. Those with reactive results were offered venepuncture in the emergency department for confirmatory testing and direct-acting antiviral treatment in clinic. The main outcome measures were the number and proportion of viremic participants that were linked to the hepatitis clinic, commenced treatment and achieved a sustained viral response. Secondary outcome measures were the proportion (%) of presentations screened that were oral antibody reactive, and the prevalence and type of HCV risk factors. RESULTS During the study period, 2408 of the 3931 (61%) presentations to the emergency department were eligible for screening. Of these 2408 patients, 1122 (47%) participated, 307 (13%) declined participation and 977 (41%) could not be approached during their time in the emergency department. Among the 1122 participants, 378 (34%) reported at least one risk factor. Subsequently, 368 (97%) of the 378 participants underwent OraQuick anti-HCV test, and 50 (14%) had a reactive result. A risk factor of ever having injected drugs was present in 44 (88%) of participants who were sero-positive. Of the 45 that had blood tested, 30 (67%) were HCV ribonucleic acid (RNA) positive. Three participants died. Of the 27 remaining participants, 10 (37%) commenced treatment and 7 of these 10 (70%) obtained a cure. There was a high rate of homelessness (24%) among anti-HCV positive participants. CONCLUSION Among emergency department participants with a risk factor for HCV, positive serology was common using a rapid point-of-care test. A history of injecting drug use was identified as the risk factor with highest yield for positive HCV serology, and is suitable as a single screening question. However, linkage to care post ED presentation was low in this marginalised population. There is a need for new pathways to improve the care cascade for marginalised individuals living with HCV infection.

Abstract
The effect of increasing mating delay on the reproductive performance and population growth rates of the vine mealybug, Planococcus ficus (Signoret) (Hemiptera: Pseudococcidae), was investigated under laboratory conditions. Virgin females were mated at 1, 3, 5, 7, 14, 21 and 28 days after emergence and reproductive and life table parameters were estimated. The pre-oviposition period (number of days between mating and the onset of oviposition) significantly decreased in females mated within 7 days, whereas females mated at older ages showed equivalent pre-oviposition periods (7 days, as shorter delays in mating did not reduce the population growth rates.

Abstract
Human granulocytic anaplasmosis (HGA) is an emerging tick-borne zoonosis worldwide. As is the case for many tick-borne diseases, the epidemiological cycle is associated to the environmental conditions, including the presence of wild vertebrate reservoir hosts, vectors, climate and vegetation. In this study a total number of 87 spleen samples of wild ruminants carcasses from Central Italy, and 77 Ixodes ricinus collected from the same dead animals were screened for Anaplasma phagocytophilum by using Real Time PCR. A. phagocytophilum DNA was detected in 75%, 66.7% and 54.2% of the spleen samples from red deer (Cervus elaphus), Apennine chamois (Rupicapra pyrenaica ornata) and roe deer (Capreolus capreolus) respectively, whereas it was detected in the 31.2% of I. ricinus. A total of 27 positive samples were characterized by sequencing a portion of the groEL gene. Two A. phagocytophilum lineages could clearly be delineated from the phylogenetic tree. Four sequences from red deer, 2 from I. ricinus and 1 from Apennine chamois clustered into lineage I together with those previously described as virulent genotypes related to HGA. The presence of A. phagocytophilum DNA in the Apennine chamois represents the first report for this Italian endemic subspecies.

Abstract
Argon plasma coagulation (APC) is a non-contact thermal method of hemostasis that has generated much attention in recent years. This endoscopic procedure is used primarily to control bleeding from lesions in the gastrointestinal tract, and also sometimes to debulk tumours in the case of patients for whom surgery is not recommended. APC involves the use of a jet of ionized argon gas (plasma) that is directed through a probe passed through the endoscope. The probe is placed at some distance from the lesion, and tissue damage is limited to superficial layers. The depth of coagulation is usually only a few millimetres. Theoretical advantages of APC include facility application, speedy treatment of multiple lesions in the case of angiodysplasias or wide areas (the base of resected polyps or tumor bleeding), safety due to reduced depth of penetration, and lower cost compared to laser.

Abstract
Over the last few years, much light has been shed on the pathogenesis of Crohn's disease. Further knowledge in this field has provided a firm basis not only in the understanding of current treatment but also for the development of new therapeutic strategies. Aim of these new agents is primarily to selectively interact with the key processes of intestinal inflammation. At present, only anti-tumour necrosis factor-alpha antibodies namely infliximab, is licensed for clinical practice but it is feasible to foresee that, in the near future, a larger range of these agents will become available. Herein, the most promising biological agents in the treatment of Crohn's disease are outlined, which patients would benefit from these agents and when they should be administered. Attention is focused on the early (top-down) or late (step-up) use of biological agents, which for their very targeted mechanism of action may be compared to guided missiles. As yet, early use of biological agents remains to be supported by convincing evidence, nevertheless it may be advocated as first-line therapy for newly diagnosed severe Crohn's disease patients, both adults and children.

Abstract
Elevated levels of glutathione S-transferases (GSTs) are among the factors associated with an increased resistance of tumors to a variety of antineoplastic drugs. Hence a major advancement to overcome GST-mediated detoxification of antineoplastic drugs is the development of GST inhibitors. Two such agents have been synthesized and tested on the human Alpha, Mu and Pi GST classes, which are the most representative targets for inhibitor design. The novel fluorescent glutathione S-conjugate L-gamma-glutamyl-(S-9-fluorenylmethyl)-L-cysteinyl-glycine (4) has been found to be a highly potent inhibitor of human GSTA1-1 in vitro (IC50=0.11+/-0.01 microM). The peptide is also able to inhibit GSTP1-1 and GSTM2-2 isoenzymes efficiently. The backbone-modified analog L-gamma-(gamma-oxa)glutamyl-(S-9-fluorenylmethyl)-L-cysteinyl-glycine (6), containing an urethanic junction as isosteric replacement of the gamma-glutamyl-cysteine peptide bond, has been developed as gamma-glutamyl transpeptidase-resistant mimic of 4 and evaluated in the same inhibition tests. The pseudopeptide 6 was shown to inhibit the GSTA1-1 protein, albeit to a lesser extent than the lead compound, with no effect on the activity of the isoenzymes belonging to the Mu and Pi classes. The comparative loss in biological activity consequent to the isosteric change confirms that the gamma-glutamyl moiety plays an important role in modulating the affinity of the ligands addressed to interact with GSH-dependent proteins. The new specific inhibitors may have a potential in counteracting tumor-protective effects depending upon GSTA1-1 activity.

Abstract
INTRODUCTION Despite the explosion of biological therapies, the old immunosuppressants continue to play a pivotal role in the management of inflammatory bowel diseases. AIM To assess the appropriateness of immunosuppressants-azathioprine, 6-mercaptopurine, methotrexate, cyclosporine A, tacrolimus (FK506), mycophenolate mofetil and thalidomide-in the treatment of inflammatory bowel disease by using RAND/University of California Appropriateness Method. METHODS The RAND method consists of a combination of evidence from the literature and experts' opinions. Appropriateness has been defined to mean that the expected health benefit exceeds the expected negative consequences by a sufficiently wide margin. A panel of 10 experts from the Italian Group for Inflammatory Bowel Disease has rated, in two rounds, on a scale from 1 to 9, the appropriateness of each indication selected by the Promoter Centre, on the basis of their own clinical experience. An indication was considered appropriate if the median of the panelists' ratings fell within the area 7-9, inappropriate in the area 1-3 and uncertain in the area 4-6. A total of 2781 indications were grouped into 13 categories (mild to moderate Crohn's disease; severe Crohn's disease; fistulizing Crohn's disease; steroid-dependant and -resistant Crohn's disease; maintenance of remission induced by medical treatment in Crohn's disease; maintenance of remission induced by surgery in Crohn's disease; mild to moderate ulcerative colitis; severe ulcerative colitis; steroid-dependant and -resistant ulcerative colitis; maintenance of remission induced by medical treatment in ulcerative colitis; extra-intestinal manifestations in inflammatory bowel disease; pregnancy and inflammatory bowel disease; azathioprine-resistant or -intolerant inflammatory bowel disease patients). RESULTS Of the 2781 scenarios, 212 (7.6%) were rated appropriate, 645 (23.2%) uncertain and 1924 (69.2%) inappropriate. The most relevant results were: in steroid-dependant or -resistant Crohn's disease, azathioprine, 6-mercaptopurine and methotrexate were defined as appropriate in 25 (86.2%) and 14 (48.3%) of the 29 scenarios respectively; in Crohn's disease, azathioprine and 6-mercaptopurine were defined as appropriate combined with Infliximab (bridge therapy); in steroid-dependant or -resistant ulcerative colitis, azathioprine and 6-mercaptopurine were defined as appropriate in 45 (77.6%) out of 58 scenarios, while methotrexate was defined appropriate only after previous azathioprine failure; in severe ulcerative colitis, cyclosporine A was defined as appropriate only after previous failure with steroids; in azathioprine-intolerant or -resistant inflammatory bowel disease patients, methotrexate was appropriate in 20 (66.7%) out of 30 scenarios; it is inappropriate to stop azathioprine treatment before conception in the presence of active disease. The use of FK506, mycophenolate mofetil and Thalidomide resulted as inappropriate or uncertain. CONCLUSIONS Results of this study show that only azathioprine, 6-mercaptopurine and methotrexate are appropriate in the treatment of inflammatory bowel diseases. Cyclosporine A was found to be appropriate only in severe ulcerative colitis after the failure of steroids. FK506, mycophenolate mofetil and Thalidomide resulted as inappropriate but experience with these agents is somewhat limited.

Abstract
Three novel carnosine analogues 7-9 containing the residue of L(+)2,3-diaminopropionic acid with different degree of N-acetylation instead of beta-alanine have been synthesized and characterized. Comparative analysis of hydrolysis by carnosinase revealed that the mono- and bis-acetylated compounds 8 and 9 are resistant to enzymatic hydrolysis and act as competitive inhibitors of this enzyme. The hydroxyl radical scavenging potential of the three analogues was evaluated by their ability to inhibit iron/H(2)O(2)-induced degradation of deoxyribose. The second-order rate constants of the reaction of compounds 7-9 with hydroxyl radical were almost identical to that of carnosine. These compounds were also found to act as protective agents against peroxynitrite-dependent damage as assessed by their ability to prevent nitration of free tyrosine induced by this species.

Abstract
The introduction and rapid diffusion of biological agents in the treatment of inflammatory bowel disease had led us to believe that the old immunosuppressive drugs were destined to disappear. However, despite a decade of clinical experience in the use of biological agents, the old immunosuppressive drugs continue to play a pivotal role in the management of inflammatory bowel disease. Various factors may account for this change of view. Aim of the present review was to summarise key information currently available regarding the use of immunosuppressive drugs in the treatment of inflammatory bowel disease.

Abstract
Mutations in the gene for the cardiac isoform of myosin binding protein C (MyBP-C) have been identified as the cause of chromosome 11-associated autosomal-dominant familial hypertrophic cardiomyopathy (FHC). Most mutations produce a truncated polypeptide that lacks the sarcomeric binding region. We have now investigated the expression pattern of the cardiac and skeletal isoforms of cMyBP-C in mice and humans by in situ hybridization and immunofluorescence microscopy using specific antibodies and probes. We demonstrate that the cardiac isoform is expressed only in cardiac muscle throughout development. The slow and fast isoforms of MyBP-C remain specific for skeletal muscle, where they can be coexpressed. Immunological evidence also suggests that an embryonic isoform of MyBP-C precedes the expression of slow MyBP-C in developing skeletal muscle. This suggests that transcomplementation of MyBP-C isoforms is possible in skeletal but not cardiac muscle.

Abstract
START is an advanced radiation therapy information system (RTIS) which connects direct information technology present in the devices with indirect information technology for clinical, administrative, information management integrated with the hospital information system (HIS). The following objectives are pursued: to support decision making in treatment planning and functional and information integration with the rest of the hospital; to enhance organizational efficiency of a Radiation Therapy Department; to facilitate the statistical evaluation of clinical data and managerial performance assessment; to ensure the safety and confidentiality of used data. For its development a working method based on the involvement of all operators of the Radiation Therapy Department, was applied. Its introduction in the work activity was gradual, trying to reuse and integrate the existing information applications. The START information flow identifies four major phases: admission, visit of admission, planning, therapy. The system main functionalities available to the radiotherapist are: clinical history/medical report linking function; folder function; planning function; tracking function; electronic mail and banner function; statistical function; management function. Functions available to the radiotherapy technician are: the room daily list function; management function: to the nurse the following functions are available: patient directing function; management function. START is a departmental client (pc-windows)-server (unix) developed on an integrated database of all information of interest (clinical, organizational and administrative) coherent with the standard and with a modular architecture which can evolve with additional functionalities in subsequent times. For a more thorough evaluation of its impact on the daily activity of a radiation therapy facility, a prolonged clinical validation is in progress.

Abstract
Traumatic aortic insufficiency is an uncommon result of blunt trauma. The typical clinical features include trauma, followed by pain (and often syncope), a musical aortic diastolic murmur, and progressive cardiac decompensation. Shock is an unusual manifestation of traumatic aortic insufficiency. In this report, a patient is described who experienced shock, a widened mediastinum, and failure to respond to fluid resuscitation after cardiac injury in an automobile accident. Emergency surgery was performed and an intimal tear was repaired. A #25 Carpentier-Edwards bioprosthesis was used to replace the aortic valve, which was avulsed from the commissure of the right and left cusps. Since aortic valve replacement offers an excellent prognosis, it should be done at the first signs of cardiac decompensation.

Abstract
LOGIST is a general program which can be used for the usual statistical interrogations and also for other basic operations such as a validity check, the transcoding and the listing of data essential to biomedicine and the human sciences. The objectives laid down for this program have enabled almost total transferability (using FORTRAN IV exclusively), simplicity in the interrogation language, clear presentation of results, reduction to a minimum of computer running time and working storage required and the facility for modification of program or addition of new sub-programs. All the possible statistical procedures have not been included yet but any such additions are quite simple. This program, despite its considerable size, can be satisfactorily used on a mini-computer. At present, it is installed on a Mitra 15 computer with a total memory capacity of 32 K words of 16 bits. Use with larger more powerful machines will increase its potential. Routine application to diverse problems (quality control of a file, transcoding, linking of data, etc....) is very satisfactory.
