Selected AbstractsFormal support, mental disorders and personal characteristics: a 25-year follow-up study of a total cohort of older peopleHEALTH & SOCIAL CARE IN THE COMMUNITY, Issue 2 2003G. Samuelsson PhD Abstract The present study was designed to describe the pattern of long-term formal support received by people with mental disorders, and to investigate the relationship between the medical, psychological and social characteristics of the participants and types of formal support. This study is based on a cohort (n = 192) of people born in 1902 and 1903 in a community in Southern Sweden. The research participants were assessed using interviews, psychological tests and medical examinations. Information was collected about the use of primary healthcare and social services. The first assessment took place when the cohort was aged 67 years, and then on eight further occasions until they were 92. The participation rate ranged from 72% to 100%. During the observation period of 25 years, 53% of people with dementia eventually received both home help and institutional care compared to 34% of people with other psychiatric diagnoses and 12% of people with good mental health. The last group had all physical health problems and/or problems with activities of daily living. However, 35% of the dementia group, 46% with other psychiatric diagnoses and 52% of people with good mental health did not receive any formal support. Males and self-employed people were significantly less likely to use formal support. The institutionalised group reported loneliness significantly more often than the other two groups. In a logistic regression analysis, loneliness, low social class, high blood pressure and low problem-solving ability were predictors of formal support use. People with a mental disorder, including dementia, were significantly more likely to use formal support compared to people with good mental health. Social factors were the main factors predicting formal support. [source] A DVB/Inmarsat hybrid architecture for asymmetrical broadband mobile satellite servicesINTERNATIONAL JOURNAL OF SATELLITE COMMUNICATIONS AND NETWORKING, Issue 2 2006Bjørn Roger Andersen Abstract In order to bridge the gap, both regulatory and technologically, between offering mobile satellite services at L-band today and broadband mobile services at C-band, Ku-band or Ka-band in the future, a short-term solution is foreseen. Therefore, a DVB/Inmarsat hybrid service offering bi-directional asymmetrical satellite connectivity, with a broadband receive channel at Ku-band based on DVB-S, and with a transmit channel at L-band based on Inmarsat Mobile Packet Data Service, has successfully been developed, implemented and tested. The article focuses on the rationale for, and a technical solution, and how this can be evolved to support use of Inmarsat Broadband Global Area Access as transmit channel at L-band. There are no regulatory issues associated with global operation of such a system, and the users can access the services using cost-efficient off-the-shelf equipment, since the well established Inmarsat and DVB standards are utilized. The system has proved its feasibility to offer services like Internet access, email access, fast file transfers, and IP streaming of audio and video, in addition to the traditional Inmarsat services.

Guney M.D. We evaluated the short- and long-term consequences of these two methods and discussed the indications for re-revascularization. Methods: Between 1998 and 2004, a total of 148 CABG patients, who were complicated with cardiac arrest, were treated with emergency re-revascularization (n = 36, group R) and ICU procedures (n = 112, group ICU). Re-revascularizations are mostly blind operations depending on clinical/hemodynamic criteria. These are: no response to resuscitation, recurrent tachycardia/fibrillation, and severe hemodynamic instability after resuscitation. Re-angiography could only be performed in 3.3% of the patients. Event-free survival of the groups was calculated by the Kaplan-Meier method. Events are: death, recurrent angina, myocardial infarction, functional capacity, and reintervention. Results: Seventy percent of patients, who were complicated with cardiac arrest, had perioperative myocardial infarction (PMI). This rate was significantly higher in group R (p = 0.013). The major finding in group R was graft occlusion (91.6%). During in-hospital period, no difference was observed in mortality rates between the two groups. However, hemodynamic stabilization time (p = 0.012), duration of hospitalization (p = 0.00006), and mechanical support use (p = 0.003) significantly decreased by re-revascularization. During the mean 37.1 ± 25.1 months of follow-up period, long-term mortality (p = 0.03) and event-free survival (p = 0.029) rates were significantly in favor of group R. Conclusion: Better short- and long-term results were observed in the re-revascularization group. [source] Prospective Evaluation of Real-time Use of the Pulmonary Embolism Rule-out Criteria in an Academic Emergency DepartmentACADEMIC EMERGENCY MEDICINE, Issue 9 2010Jeffrey A. Kline MD Abstract Objectives:, The pulmonary embolism rule-out criteria (PERC rule) is a nine-component decision rule derived to exclude pulmonary embolism (PE) without the use of formal diagnostic testing (D-dimer, computed tomography pulmonary angiography, ventilation,perfusion lung scanning, or venous ultrasonography) when all nine components are negative ("PERC negative"). This study examined whether clinicians who document PERC negative also document results of all nine components of the PERC rule. Methods:, This was a pilot study at a single-center, urban teaching emergency department (ED) with a residency program in emergency medicine. Patients were over 17 years of age with at least one of nine predefined chief complaints. Clinicians were asked three questions regarding suspicion for PE, intent to use the PERC rule, and the result. Charts were independently reviewed by two authors for fidelity of the nine PERC components. Patients were followed for PE outcome at 14 days. Results:, The study examined 526 patients cared for by 82 clinicians, who indicated suspicion for PE in 183 of 526 (35%) and intent to use the PERC rule in 115 of 526 (22%) cases, of whom 65 of 115 were documented as PERC negative. No formal test for PE was ordered in 49 of 65 (75%), and 46 of 49 had incomplete documentation to support PERC negative. The most common deficiency was omission of two risk factors for PE in the rule (prior venous thromboembolism or recent surgery). Six patients had PE diagnosed within 14 days, but none of these had been deemed PERC negative. Conclusions:, Clinicians seldom document all nine data elements of the PERC rule in patients they deem PERC negative. These data suggest the need for paper or electronic aids to support use of the PERC rule.

The aim of this review was to provide an update on alcoholic cirrhosis, with an emphasis on recent findings. Increased alcohol consumption in developing countries is expected to increase cirrhosis mortality. There is a need, therefore, to develop new approaches to the prevention of ALD, including more attention to co-factors that may increase risk of ALD (i.e., obesity and diabetes, chronic HCV infection, and smoking). Furthermore, a better understanding of the pathological mechanisms on the basis of alcohol cirrhosis represents a cornerstone in order to develop new pharmacological treatments. Inflammatory and immune responses along with oxidative stress and alterations in adipokine secretion might contribute in different ways to the evolution of alcohol-induced fibrosis/cirrhosis. As of this date, patients with severe alcoholic hepatitis with a Maddrey Discriminant Factor (MDF) 32 should be offered pentoxifylline and/or corticosteroids unless contraindications exist. For ambulatory patients, S-adenosylmethionine (SAMe) may be considered in a motivated patient with nutritional support. Current studies do not support use of anti-tumor necrosis factor (TNF)-alpha antibody. Finally, achieving total alcohol abstinence should represent the main aim in the management of patients affected by any stage of cirrhosis. In the last decades, several drugs able to increase abstinence and prevent alcohol relapse have been evaluated and some of them have obtained approval for alcohol dependence. Patients with alcoholic cirrhosis; however, are usually excluded from such treatments. A recent study demonstrated the efficacy and safety of baclofen in inducing and maintaining alcohol abstinence in cirrhotic alcohol-dependent patients with cirrhosis. All together the information available suggests the need of a multimodal approach in the clinical management of these patients. [source] The Alcohol Use Disorders Identification Test: An Update of Research FindingsALCOHOLISM, Issue 2 2007Duane F. Reinert Background: The Alcohol Use Disorders Identification Test (AUDIT) has been extensively researched to determine its capability to accurately and practically screen for alcohol problems. Methods: During the 5 years since our previous review of the literature, a large number of additional studies have been published on the AUDIT, abbreviated versions of it, its psychometric properties, and the applicability of the AUDIT for a diverse array of populations. The current article summarizes new findings and integrates them with results of previous research. It also suggests some issues that we believe are particularly in need of further study. Results: A growing body of research evidence supports the criterion validity of English version of the AUDIT as a screen for alcohol dependence as well as for less severe alcohol problems. Nevertheless, the cut-points for effective detection of hazardous drinking as well as identification of alcohol dependence or harmful use in women need to be lowered from the originally recommended value of 8 points. The AUDIT-C, the most popular short version of the AUDIT consisting solely of its 3 consumption items, is approximately equal in accuracy to the full AUDIT. Psychometric properties of the AUDIT, such as test,retest reliability and internal consistency, are quite favorable. Continued research is urged to establish the psychometric properties of non-English versions of the AUDIT, use of the AUDIT with adolescents and with older adults, and selective inclusion of alcohol biomarkers with the AUDIT in some instances. Conclusions: Research continues to support use of the AUDIT as a means of screening for the spectrum of alcohol use disorders in various settings and with diverse populations. [source] Impact of primary tumour stage on survival in dogs with solitary lung tumoursJOURNAL OF SMALL ANIMAL PRACTICE, Issue 2 2008G. A. Polton Objectives: The objective of this study was to determine simple prognostic criteria for differentiation of canine solitary lung tumour cases into those that will and will not benefit from thoracic surgery. Methods: This was a retrospective study using the records of cases presented to Davies Veterinary Specialists, Hitchin, UK, from December 1998 to December 2005. Survival analyses were performed using the Kaplan-Meier and logrank methods. Potentially significant variables were evaluated by multivariate Cox analysis. Results: Forty-two patients met the inclusion criteria. Primary tumour stage T1, absence of neoplastic lymph nodes and metastases, and papillary tumour type were statistically significant favourable prognostic indicators on univariate analysis. Multivariate analysis attributed significance to primary tumour stage T1 and papillary type only. Median survival times were 555 days for T1N0M0 tumours of papillary type and 72 days for the remainder. Clinical Significance: Survival time following surgery in dogs with primary lung tumours was poor except in clinical stage T1N0M0 cases. These data support use of clinical techniques to dichotomise cases as T1N0M0 or other, improving decision making in thoracic surgery. These data validate initiation of prospective studies examining the role of chemotherapy in the management of advanced cases. [source] The Alcohol Use Disorders Identification Test (AUDIT): A Review of Recent ResearchALCOHOLISM, Issue 2 2002Duane F. Reinert Background: Efficient, inexpensive screening for early stage alcohol problems is important in health care settings. The Alcohol Use Disorders Identification Test (AUDIT) has been studied extensively to establish its value in this regard. Methods: A literature search that used EtOH as a database was conducted to identify studies published on the AUDIT through September 2001. Keywords used for the search were "Alcohol Use Disorders Identification Test" and "AUDIT." All studies reporting psychometric properties of the measure were reviewed with particular attention being given to the period 1996 and later. A small number of additional references were located by noting their citation in other studies reviewed. Results: Although more research is needed on non-English versions to establish their psychometric properties, at least in its English edition, the AUDIT demonstrates sensitivities and specificities comparable, and typically superior, to those of other self-report screening measures. Test-retest reliability and internal consistency are also quite favorable. For males, the AUDIT-C, a shortened version of the AUDIT, appears approximately equal in validity to the full scale. Conclusions: Recent research continues to support use of the AUDIT as a means of screening for alcohol use disorders in health care settings in the United States. [source] Ultrasonographic measurement of endometrial changes following discontinuation of tamoxifen treatment in postmenopausal breast cancer patientsBJOG : AN INTERNATIONAL JOURNAL OF OBSTETRICS & GYNAECOLOGY, Issue 9 2000Ilan Cohen MD Objective To assess whether there is a decrease in endometrial thickness following discontinuation of tamoxifen treatment as measured by ultrasound. Design Prospective study. Setting Department of Obstetrics and Gynaecology, Sapir Medical Centre, Kfar-Saba, Israel. Population Fifty-eight postmenopausal women with breast cancer who were treated with tamoxifen. Methods Transvaginal ultrasonographic measurements of endometrial thickness. Main outcome measures Evaluation of the changes of endometrial thickness and the frequency the endometrium reached a thickness of , 5 mm at different time intervals after stopping tamoxifen treatment. Results There was a significant decrease in median thickness of the endometrium, within six months after stopping tamoxifen, from 7.75 mm measured at the last ultrasonographic study performed before tamoxifen discontinuation down to 5.2 mm (P= 0.002). There were no further reductions in endometrial thickness, and it remained constantly low in subsequent ultrasonographic studies which were performed at various times up to 30 months following the discontinuation of tamoxifen treatment. While taking tamoxifen, only 25.9% of the women had an endometrial thickness of , 5 mm. This proportion doubled in their first six months after stopping. Conclusions Median thickness of endometrial thickness significantly reduced within six months following tamoxifen discontinuation, and remained constantly low thereafter. This finding may support use of ultrasonographic imaging for the measurement of tamoxifen's effect on the endometrium of postmenopausal breast cancer patients. [source] | ||||||||||
