Abstract
Abstract
Background
Novel echocardiographic software allows for layer-specific evaluation of myocardial deformation by 2-dimensional speckle tracking echocardiography. Endocardial, epicardial- and whole wall global longitudinal strain (GLS) may be superior to conventional echocardiographic parameters in predicting all-cause mortality in patients with heart failure with reduced ejection fraction (HFrEF).
Purpose
The purpose of this study was to investigate the prognostic value of endocardial-, epicardial- and whole wall GLS in patients with HFrEF in relation to all-cause mortality.
Methods
We included and analyzed transthoracic echocardiographic examinations from 1,015 patients with HFrEF. The echocardiographic images were analyzed, and conventional and novel echocardiographic parameters were obtained. A p value in a 2-sided test <0.05 was considered statistically significant. Cox proportional hazards regression models were constructed, and both univariable and multivariable hazard ratios (HRs) were calculated.
Results
During a median follow-up time of 40 months, 171 patients (16.8%) died. A lower endocardial (HR 1.17; 95% CI (1.11–1.23), per 1% decrease, p<0.001), epicardial (HR 1.20; 95% CI (1.13–1.27), per 1% decrease, p<0.001), and whole wall (HR 1.20; 95% CI (1.14–1.27), per 1% decrease, p<0.001) GLS were all associated with higher risk of death (Figure 1). Both endocardial (HR 1.12; 95% CI (1.01–1.23), p=0.027), epicardial (HR 1.13; 95% CI (1.01–1.26), p=0.040) and whole wall (HR 1.13; 95% CI (1.01–1.27), p=0.030) GLS remained independent predictors of mortality in the multivariable models after adjusting for significant clinical parameters (age, sex, total cholesterol, mean arterial pressure, heart rate, ischemic cardiomyopathy, percutaneous transluminal coronary angioplasty and diabetes) and conventional echocardiographic parameters (left ventricular (LV) ejection fraction, LV mass index, left atrial volume index, deceleration time, E/e', E-velocity, E/A ratio and tricuspid annular plane systolic excursion). No other echocardiographic parameters remained an independent predictors after adjusting. Furthermore, endocardial, epicardial and whole wall GLS had the highest C-statistics of all the echocardiographic parameters.
Conclusion
Endocardial, epicardial and whole wall GLS are independent predictors of all-cause mortality in patients with HFrEF. Furthermore, endocardial, epicardial and whole wall GLS were superior prognosticators of all-cause mortality compared with all other echocardiographic parameters.

Abstract
BACKGROUND The food-borne viruses in Europe (FBVE) network database was established in 1999 to monitor trends in outbreaks of gastroenteritis due to noroviruses (NoVs), to identify major transmission routes of NoV infections within and between participating countries and to detect diffuse international food-borne outbreaks. METHODS We reviewed the total of 9430 NoV outbreak reports from 13 countries with date of onset between 1 January 2002 and 1 January 2007 for representativeness, completeness and timeliness against these objectives. RESULTS Rates of reporting ranged from a yearly average of 1.8 in 2003 to 11.6 in 2006. Completeness of reporting of an agreed minimum dataset improved over the years, both for epidemiological and virological data. For the 10 countries that provided integrated (epidemiological AND virological) reporting over the 5-year period, the completeness of the minimum dataset rose from 15% in 2003 to 48% in 2006. Two countries have not been able to combine both data types due to the structure of the national surveillance system (England and Wales and Germany). Timeliness of reporting (median days between the onset of an outbreak and the date of reporting to the FBVE database) differed greatly between countries, but gradually improved to 47 days in 2006. CONCLUSION The outbreaks reported to the FBVE reflect the lack of standardization of surveillance systems across Europe, making direct comparison of data between countries difficult. However, trends in reported outbreaks per country, distribution of NoV genotypes, and detection of diffuse international outbreaks were used as background data in acute questions about NoV illness and the changing genotype distribution during the 5-year period, shown to be of added value. Integrated reporting is essential for these objectives, but could be limited to sentinel countries with surveillance systems that allow this integration. For successful intervention in case of diffuse international outbreaks, completeness and timeliness of reporting would need to be improved and expanded to countries that presently do not participate.

Abstract
This study measured quantitatively and explored qualitatively silencing behaviors and affectivity (mood) in women living with HIV/AIDS and confirmed the validity of the Silencing the Self Scale and the Positive and Negative Affect Scale. Silencing behaviors are interpersonal communication styles that suppress personal needs and feelings to preserve relationships with others. Silencing behaviors serve as protective strategies that allow one to divorce oneself from an overbearing culture. Affectivity is a way of measuring one's personal mood state by a positive to negative continuum. The results indicate that the women silenced themselves profoundly, especially when it came to putting the needs of their children or dependents before their own. The women also had high levels of negative affectivity. The research findings from this study extend nursing knowledge by addressing the unique social processes of women living with HIV/AIDS within health care service structures and significant social groups. Further exploration of "silencing" as a phenomenon of this group through measurement and experience will help define specific interventions that are meaningful to and for women living with HIV/AIDS.

Abstract
The risk of protein calorie malnutrition among the community dwelling elderly is high. If undetected or untreated malnutrition can raise risks of morbidity and mortality. Therefore, improving screening, assessment and treatment of malnutrition, particularly in ambulatory settings that serve the elderly is imperative. The aim of this paper is to briefly detail the diagnostic criteria for protein calorie malnutrition and discuss the special considerations necessary in evaluating risk and causes of malnutrition in the elderly. We conclude with a review of current management options and discuss the cost effectiveness and potential inappropriate use of commercially manufactured oral nutritional supplements.

Abstract
The quinoline-3-carboxamide, linomide, protects non-obese diabetic mice from diabetes. The effects of linomide on insulin needs and beta cell function were studied in recent juvenile Type I diabetes in a double-blind trial. Patients with recent onset diabetes were randomly assigned to treatment with a fixed dose of 2.5 mg linomide (42 patients) or placebo (21 patients) for 1 year, in addition to insulin and diet. Glycated haemoglobin was 10-15% lower at 9 months (p = 0.003) and 12 months (p < 0.05) in the linomide group. The insulin dose was 32-40% smaller in the linomide group at 3 (p < 0.03), 6 (p < 0.02), 9 (p < 0.001) and 12 months (p = 0.01). Insulin doses correlated negatively with C peptide values (p = 0.001-0.002). The trend for higher C peptide values in the linomide group did not reach significance. In a post hoc subgroup analysis performed in 40 patients (25 from the linomide group and 15 from the placebo group) who still had detectable residual beta cell function at entry, linomide was associated with 45-59% higher C peptide value at 6 months (p < 0.05), 9 months (p < 0.05) and 12 months (p < 0.05). The main adverse effects of linomide were mild transitory anaemia (45 vs 10% in the linomide and placebo groups), thrombocytopenia (24 vs 10%), and mild joint discomfort (45 vs 5%) with no clinical signs. In conclusion, low-dose linomide reduced the insulin needs in patients with juvenile Type I diabetes of recent onset and improved beta cell function in patients who still had detectable beta cell function at entry. These results support further clinical and experimental studies to define the effects of linomide in Type I diabetes provided the safety of linomide is reliably established.

Abstract
This article reports the findings from a study of women detained in the women's jail at Rikers Island Correctional Facility in New York City. Interviews were used to gather data on five variables: women's childhood physical and sexual abuse, victimization as adults, drug use, homelessness, and suicide. These findings were analyzed along with biological data on STDs. The conclusions suggest that an association exists between childhood physical and sexual abuse and drug use, suicide attempts, and homelessness in adulthood. The findings indicate that these experiences are common for the population under study, and that a positive association between the variables exists in a sample of incarcerated women. Implications and questions for further research are discussed.

Abstract
OBJECTIVES To better identify inmates with tuberculosis infection at admission and to have more accurate estimates of conversion rates with annual retesting, I evaluated two-step tuberculin skin testing of newly admitted inmates at the Addiction Center of the Massachusetts Department of Corrections. METHOD In a population of inmates admitted to the Addiction Center between January and May 1994, a second tuberculin skin test was performed 1 week after the first for those who initially had a negative response. RESULTS There were 628 admissions during the study period; 51 of these inmates (8%) had a history of positive skin test results. Of the 570 initial tuberculin skin tests that were read, 12 (2.1%) had positive results. Five of 510 second tuberculin skin tests (1%) had positive results. CONCLUSION I evaluated the feasibility and utility of two-step tuberculin skin testing among newly admitted inmates at a Massachusetts correctional facility. We identified 40% more inmates with positive tuberculin skin test results after conducting 510 additional skin tests. Unlike the Addiction Center inmates, newly admitted inmates at other reception facilities are subject to interfacility transfer, and the rate of reading initial tuberculin skin tests is significantly lower than the 99% obtained at the Addiction Center. I expect serial testing to increase the identification of tuberculosis infected inmates at all facilities; however, its implementation should be deferred until a higher reading rate is obtained for the initial skin test.

Abstract
BACKGROUND Adjuvant systemic therapy prolongs disease-free and overall survival in both pre- and postmenopausal patients. Available data shown benefit from multi-agent chemotherapy, prolonged tamoxifen treatment, and ovarian ablation, and that the combination of chemo- and endocrine therapy might be advantageous. In 1978 the International (Ludwig) Breast Cancer Study Group (IBCSG) initiated four complementary randomized controlled clinical trials to evaluate the roles of chemo-endocrine combinations or endocrine therapy alone in specific populations defined by risk (for pre- and perimenopausal patients) or by age (for postmenopausal patients). The results at 10 and 13 years' median follow-up for these trials are summarized in this report and are compared to those of the Overview meta-analysis with regard to chemo-endocrine or endocrine therapy combinations. Furthermore, types of first relapses by sites and second malignant diseases are reported. PATIENTS AND METHODS 1601 evaluable patients with node positive disease were included into the studies I-IV. In Trial I (491 premenopausal patients with 1-3 positive axillary nodes) we studied the addition of low-dose continuous prednisone (p) to a cyclophosphamide-methotrexate-fluorouracil (CMF) combination. In Trial II 327 premenopausal patients with four or more positive axillary nodes were randomized to one year CMFp or to a surgical oophorectomy followed by CMFp. In Trial III (463 postmenopausal patients 65 years old or younger), combined chemoendocrine therapy (one year of CMFp plus tamoxifen (T)) was compared to endocrine therapy (1 year of p + T) or to surgery alone. In Trial IV 320 postmenopausal patients 66 to 80 years old were treated either by surgery alone or by surgery followed by 1 year prednisone and tamoxifen. RESULTS In Trial I the addition of prednisone allowed a higher dose of cytotoxics to be administered compared with CMF alone. Despite this increased dose intensity, 13-year disease-free survival (DFS) and overall survival (OS) were similar for the two treatment groups (49% vs. 52% DFS, 59% vs. 65% OS for CMFp vs. CMF). In Trial II the addition of surgical oophorectomy to CMFp yielded an improved outcome which approached statistical significance for the subset of 107 patients known to have estrogen receptor-positive tumors (DFS, 23% vs. 15%, p = 0.13; OS, 41% vs. 30%, p = 0.12). In Trial III combined chemoendocrine therapy improved DFS and OS compared with endocrine therapy alone (p + T) given for the same duration, or no adjuvant treatment (DFS, 35% vs. 25% vs. 14%, p < 0.0001; OS, 48% vs. 36% vs. 32%, p = 0.01). In Trial IV p + T improved DFS compared with no adjuvant therapy (27% vs. 15%, p = 0.004). Despite competing risks for this elderly population, OS was also improved but the result was not statistically significant (34% vs. 22%, p = 0.08). CONCLUSIONS The overall results of these four trials indicate that the continuation of investigations on combined chemo-endocrine therapies is warranted. The prognosis of the patients, all node-positive, treated with the most effective adjuvant treatment is such that there is a large potential for improvement.

Abstract
BACKGROUND An increasing incidence of tuberculosis has been observed in the New York City correctional system. METHODS The diagnosis of active tuberculosis in persons within the correctional setting results in an investigation, with the identification and screening of contacts. RESULTS Thirty-four such investigations in the past 2 years in the New York City correctional system, where all inmates are screened for tuberculosis on admission, have resulted in an overall tuberculin skin test conversion rate of 6.74% in 1306 inmates. In 21 of these investigations the index had both smears and cultures positive for Mycobacterium tuberculosis and the conversion rate was 7.37% in 719 contacts tested. In seven investigations the index patient had a culture only positive for M. tuberculosis and the conversion rate was 6.58% in 243 inmates. In six investigations in which the index patients were subsequently found to have nontuberculous pneumonia or mycobacteria other than M. tuberculosis the conversion rate was 5.52% in 344 inmates. These rates are not statistically different. CONCLUSIONS Whether the observed conversions in these events or in any of the contact investigations are due to intramural spread, anergy on admission, the booster phenomenon, or incubation of disease on admission is not known. The 5.5% conversion rate in those exposed to inmates confirmed not to have tuberculosis suggests the influence of booster phenomenon and consideration of two-step testing on admission.

Abstract
Smallpox was officially declared eradicated from the world in 1980. Earlier, in 1972, over 50 nations signed the Biological Weapons Convention renouncing this entire category of weapons. Despite this international agreement, both the United States and the Soviet Union continue to vaccinate their military troops against smallpox, thus implying that each fears the other might still use it in biological warfare. Vaccination is not a harmless procedure, and vaccinia infections continue to be reported in troops and their contacts. Negotiating an end to the vaccination of troops would be a final step in ending the fear of smallpox.
