    Various ecological studies report a reduction in cardiovascular disease mortality risk with increasing magnesium levels in drinking water. Most of the studies done in this field were epidemiologic studies.The aim of the present study was to examine whether magnesium addition to drinking water can affect risks of cardiac disease. The study included five groups of male albino rats. The rats received either tap water or water containing 5, 10, 20 g of magnesium sulfate per liter. During the whole experiment, all the groups received hypercholesterolemic diet except for the normal control which received normal basal diet. At the end of the experiment, blood was drawn for the determination of plasma magnesium, lipid profile and liver function. In addition, the extent of obesity was determined using the body mass index (BMI). In all groups magnesium addition was associated with higher levels of plasma magnesium. The blood analysis showed a significant decrease in serum total cholesterol, triglycerides, LDL- cholesterol and VLDL- cholesterol, while there was a significant increase in HDL- cholesterol in groups received magnesium sulfate in drinking water, compared with the hypercholesterolemic group received tap water. GOT, GPT and ALP followed the same trend. The addition of MgSO4 to the drinking water results in significant decrease in BMI of the magnesium treated groups relative to the hypercholesterolemic control. These results showed that high magnesium concentration in drinking water is capable of decreasing some cardiac disease risk factors in male albino rats.

    Only a few studies provided data on the clinical history of sepsis within internal Medicine units.The aim of the study was to assess the short-term mortality and to evaluate the prognostic risk factors in a large cohort of septic patients treated in internal medicine units.Thirty-one internal medicine units participated to the study. Within each participating unit, all admitted patients were screened for the presence of sepsis.A total of 533 patients were included; 78 patients (14.6%, 95%CI 11.9, 18.0%) died during hospitalization; mortality rate was 5.5% (95% CI 3.1, 9.6%) in patients with nonsevere sepsis and 20.1% (95%CI 16.2, 28.8%) in patients with severe sepsis or septic shock. Severe sepsis or septic shock (OR 4.41, 95%CI 1.93, 10.05), immune system weakening (OR 2.10, 95%CI 1.12, 3.94), active solid cancer (OR 2.14, 95% CI 1.16, 3.94), and age (OR 1.03 per year, 95% CI 1.01, 1.06) were significantly associated with an increased mortality risk, whereas blood culture positive for Escherichia coli was significantly associated with a reduced mortality risk (OR 0.46, 95%CI 0.24, 0.88).In-hospital mortality of septic patients treated in internal medicine units appeared similar to the mortality rate obtained in recent studies conducted in the ICU setting

    Clinical Features and Outcome of 79 Dogs With Digital Squamous Cell Carcinoma Undergoing Treatment: A SIONCOV Observational Study

    In dogs, digit squamous cell carcinoma (SCC) is uncommon. Clinical signs are frequently underestimated, leading to a diagnostic delay. The purpose of this retrospective study was to report our experience regarding the clinical presentation, diagnostic work-up, treatment and outcome of 79 client-owned dogs with SCC of the digit. The greatest majority (84.8%) of dogs was dark-coated. Schnauzers represented approximately one third of the study population, and had a poorer outcome compared with other breeds. The majority of SCCs occurred in the front limbs (61%), and bone lysis was frequently observed (92.4%). Approximately 9% of dogs had involvement of multiple digits, and this was associated with a shorter time to progression (TTP; P = 0.047). Similarly, a duration of clinical signs >90 days was associated with a shorter TTP (P = 0.02). Regional lymph node metastases were documented in 17.7% of dogs at admission and were significantly associated with tumor-related death (P < 0.001). At presentation, none of the dogs had evidence of distant metastasis. Digit amputation achieved adequate local tumor control in the majority of cases. Adjuvant chemotherapy and radiation therapy were carried out in 21.5% of cases, with uncertain benefit. Due to the relatively non-aggressive clinical behavior of digit SCC, chemotherapy should only be offered in the case of metastatic disease. Approximately one fourth of dogs developed de novo SCCs during the follow-up. Careful examination of the digits should be encouraged in breeds considered at high risk and in dogs with a previous history of digital SCC

    An empirical analysis of conviction patterns, change over the life-course and external influences in relation to sexual offending behaviour

    Get PDF
    This PhD uses statistical analysis and qualitative interviews to analyse behaviour patterns in the context of causal theories of sexual offending and desistance from it, with a particular emphasis on socio-cultural reasons why people offend, stop offending, or offend at different points in life. This research makes an original contribute to the literature in a number of ways. There are six main findings from this research that contribute to the literature in this area. One of the key findings is that there is substantial heterogeneity of offending behaviour amongst sexual offenders, suggesting that there is no one-size-fits-all approach for prevention, intervention or management. There was support in the research for a link between sexual offending and prolific non-sexual offending, but this only appeared to be one of several different sexual offending pathways. Other groups of offenders displayed considerable specialism in their offending (in terms of type of sexual offence and the fact that they had often only been convicted of sexual offences). This was magnified by the finding that offending rates were generally lower for sexual convictions than for other convictions: in fact, the vast majority of people in the dataset only had convictions for one sexual offence. There was evidence from the qualitative interviews that adverse life events were a contributory factor to sexual offending, and the thesis has found that there is support for both psychological and socio-cultural causes (including gender-based elements), as well as an interaction between the two. It also suggested that there is evidence that sexual offending is not stable over the life-course, and that situational factors appear to be important in terms of determining behavioural change. Implications for prevention, intervention and management of sexual offenders are discussed

    A comparative analysis of a disposable and a reusable pedicle screw instrument kit for lumbar arthrodesis: integrating HTA and MCDA

    Objective: Lumbar arthrodesis is a common surgical technique that consists of the fixation of one or more motion segments with pedicle screws and rods. However, spinal surgery using these techniques is expensive and has a significant impact on the budgets of hospitals and Healthcare Systems. While reusable and disposable instruments for laparoscopic interventions have been studied in literature, no specific information exists regarding instrument kits for lumbar arthrodesis. The aim of the present study was to perform a complete health technology assessment comparing a disposable instrument kit for lumbar arthrodesis (innovative device) with the standard reusable instrument. Methods: A prospective and observational study was implemented, by means of investigation of administrative records of patients undergoing a lumbar arthrodesis surgical procedure. The evaluation was conducted in 2013, over a 12- month time horizon, considering all the procedures carried out using the two technologies. A complete health technology assessment and a multi-criteria decision analysis approach were implemented in order to compare the two alternative technologies. Economic impact (with the implementation of an activity based costing approach), social, ethical, organisational, and technology-related aspects were taken into account. Results: Although the cost analysis produced similar results in the comparison of the two technologies (total cost equal to € 4,279.1 and € 4,242.6 for reusable instrument kit and the disposable one respectively), a significant difference between the two instrument kits was noted, in particular concerning the organisational impact and the patient safety. Conclusions: The replacement of a reusable instrument kit for lumbar arthrodesis, with a disposable one, could improve the management of this kind of devices in hospital settings

    DO JURORS HOLD AUDITORS TO A DIFFERENT NEGLIGENCE STANDARD UNDER U.S. GAAP AND IFRS?

    In order to fulfill the requirements of East Carolina University’s Honors College, I created the research study described in this paper to examine the effects on auditor liability under United States Generally Accepted Accounting Principles compared to the International Financial Reporting Standards. The Financial Accounting Standards Board and the International Accounting Standards Board have been working towards convergence between U.S. GAAP, a rules-based system, and IFRS, a principles-based system. This research study examines whether potential jurors would hold auditors to a different negligence standard between rules-based and principles-based accounting. This study also explores how juror assessments of auditor responsibility differ when auditor liability is limited, as opposed to, unlimited. An experiment was conducted with students at a large state university representing jurors. I found evidence that auditor liability was held to a higher dollar value under unlimited liability and when relevant accounting standards were rules-based
