Aim: The aim of the current study is to assess the mortality prediction accuracy of circulating cell-free DNA (CFD) level at admission measured by a new simplified method., Materials and Methods: CFD levels were measured by a direct fluorescence assay in severe sepsis patients on intensive care unit (ICU) admission. In-hospital and/or twenty eight day all-cause mortality was the primary outcome., Results: Out of 108 patients with median APACHE II of 20, 32.4% have died in hospital/or at 28-day. CFD levels were higher in decedents: median 3469.0 vs. 1659 ng/ml, p<0.001. In multivariable model APACHE II score and CFD (quartiles) were significantly associated with the mortality: odds ratio of 1.05, p = 0.049 and 2.57, p<0.001 per quartile respectively. C-statistics for the models was 0.79 for CFD and 0.68 for APACHE II. Integrated discrimination improvement (IDI) analyses showed that CFD and CFD+APACHE II score models had better discriminatory ability than APACHE II score alone., Conclusions: CFD level assessed by a new, simple fluorometric-assay is an accurate predictor of acute mortality among ICU patients with severe sepsis. Comparison of CFD to APACHE II score and Procalcitonin (PCT), suggests that CFD has the potential to improve clinical decision making.

Background: Laparoscopic adjustable gastric banding surgery has become one of the most common restrictive surgical procedures for treatment of morbid obesity worldwide. Although short-term respiratory complications are well known, long-term data is scarce. We investigated the manifestations of major pulmonary complications showed at least six months after the procedure., Methods: A retrospective cohort study was conducted at a tertiary university medical center in the five years period of 2006-2010. We included every patient who had had major respiratory complication who needed hospitalization, at least 6 months after laparoscopic adjustable gastric banding procedure. Demographic, pre-operative and post-operative clinical data were collected. We documented respiratory symptoms, results of physical examination, pulmonary function tests, and imaging as well as therapies given and outcome., Results: Out of 2100 patients who underwent LAGB, thirty subjects, mean age of 45.7 (range 29-64) with an equal number of males and females were included. Mean interval between operation and onset of respiratory symptoms was 51.5 months (range 10-150 months). All had dyspeptic complaints which included: regurgitation, fullness after meals, dysphagia and food aspiration with esophageal dilatation. Major respiratory complications included aspiration pneumonia (19) including pulmonary abscess (4) and empyema (2), exacerbation of asthma (3) and hemoptysis (1). Additionally we documented the emergence of chronic diseases such as interstitial lung disease (5) and bronchiectasis (3). One patient developed acute respiratory distress syndrome due to aspiration pneumonia and eventually died in the intensive care unit. The main mode of therapy was deflation of the gastric band. Those who refused to deflate or remove the gastric banding continued to suffer from dyspeptic and respiratory symptoms including recurrent pulmonary abscess., Conclusion: Although laparoscopic adjustable gastric banding surgery has few short-term risks and is highly effective at achieving weight reduction, we found an increased risk for major respiratory complications in the long-term period. The obesity epidemic and the increased use of surgical techniques to treat obesity will most likely lead to an increase in the incidence of long-term post-operative respiratory complications. This entity is probably under-reported and needs further research into how to reduce its incidence and morbidity., (Copyright © 2012 Elsevier Ltd. All rights reserved.)

Background: Chronic obstructive pulmonary disease (COPD) is characterized by progressive exertional and resting dyspnea and is associated with major co-morbidities. Hemoglobin level disorders (anemia and polycythemia) prevalence among patients and the relationship between them and the clinical expression are still not characterized unequivocally. The main purpose of this work is to test the association between anemia and hospitalizations. The presence of such a link may promote the diagnosis and treatment aimed at the patient's hemoglobin levels., Hypothesis: Anemia in patients with COPD is associated with an increased number of hospitalizations., Methods: A retrospective cohort study analysis, conducted on a group of COPD patients (n = 333) followed in the Pulmonology Institute of the Soroka University Medical Center in the years 2003-2009. Demographic physiological and clinical characteristics were compared between anemic, polycythemic and normal hemoglobin patients. Using statistical models, we examined the relationship between the presence of anemia and clinical outcome., Results: Anemia was found in 79 patients (24%) and polycythemia among seven patients (2%). No difference was found between the groups in terms of number of hospitalizations, number of hospitalization days and ventilator events. There was a higher rate of co-morbidities (such as heart failure, chronic kidney disease) among anemic patients. There were also lower values of BMI and lung function and a higher proportion of men among anemic patients., Conclusions: Anemia in patients with COPD was not associated with an increase in the number of severe exacerbations. More studies are needed to clarify the threshold of a hemoglobin level below which there is an increase in the rate of hospitalizations.

Background: The Dead Sea region, the lowest in the world at 410 meters below sea level, is considered a potent climatotherapy center for the treatment of different chronic diseases., Objective: To assess the prevalence of chronic diseases and the quality of life of residents of the Dead Sea region compared with residents of the Ramat Negev region, which has a similar climate, but is situated 600 meters above sea level., Methods: An observational study based on a self-administered questionnaire. Data were collected from kibbutz (communal settlement) members in both regions. Residents of the Dead Sea were the study group and of Ramat Negev were the control group. We compared demographic characteristics, the prevalence of different chronic diseases and health-related quality of life (HRQOL) using the SF-36 questionnaire., Results: There was a higher prevalence of skin nevi and non-inflammatory rheumatic diseases (NIRD) among Dead Sea residents, but they had significantly higher HRQOL mean scores in general health (68.7 ± 21 vs. 64.4 ± 22, p = 0.023) and vitality (64.7 ± 17.9 vs. 59.6 ± 17.3, p = 0.001), as well as significantly higher summary scores: physical component score (80.7 ± 18.2 vs. 78 ± 18.6, p = 0.042), and mental component score (79 ± 16.4 vs. 77.2 ± 15, p = 0.02). These results did not change after adjusting for social-demographic characteristics, health-related habits, and chronic diseases., Conclusions: No significant difference between the groups was found in the prevalence of most chronic diseases, except for higher rates of skin nevi and NIRD among Dead Sea residents. HRQOL was significantly higher among Dead Sea residents, both healthy or with chronic disease.

Background: Balneotherapy, traditionally administered during a continuous stay at the Dead Sea area, has been shown to be effective for patients suffering from knee osteoarthritis., Objectives: To evaluate the effectiveness of an intermittent regimen of balneotherapy at the Dead Sea for patients with knee osteoarthritis., Methods: Forty-four patients with knee osteoarthritis were included in a prospective randomized single-blind controlled study. The patients were divided into two groups: a treatment group (n=24), which were treated twice weekly for 6 consecutive weeks in a sulfur pool heated to 35-36 degrees C, and a control group (n=20) treated in a Jacuzzi filled with tap water heated to 35-36 degrees C. Participants were assessed by the Lequesne index of osteoarthritis severity, the WOMAC index, the SF-36 quality of health questionnaire, VAS scales for pain (completed by patients and physicians), and physical examination., Results: A statistically significant improvement, lasting up to 6 months, was observed in the treatment group for most of the clinical parameters. In the control group the only improvements were in the SF-36 bodily pain scale at 6 months, the Lequesne index at 1 month and the WOMAC pain score at the end of the treatment period. Although the patients in the control group had milder disease, the difference between the two groups was not statistically significant., Conclusions: Intermittent balneotherapy appears to be effective for patients with knee osteoarthritis.

Background & Aims: Immune dysregulation, polyendocrinopathy, enteropathy, X-linked (IPEX; OMIM 304930) syndrome is a congenital syndrome characterized by autoimmune enteropathy, endocrinopathy, dermatitis, and other autoimmune phenomena. In the present work, we aimed to uncover the molecular basis of a distinct form of IPEX syndrome presenting at the edge of autoimmunity and severe allergy., Methods: The FOXP3 gene was sequenced, FOXP3 messenger RNA (mRNA) was quantified by real-time polymerase chain reaction (PCR), and protein expression in peripheral blood lymphocytes was analyzed by flow cytometry after intracellular staining. In coculture experiments (CD4(+)CD25(-) and CD4(+)CD25(+) cells), the functions of regulatory T cells were analyzed. Expression of interferon gamma and interleukin 2 and 4 mRNA within the inflamed intestinal mucosa was quantified by real-time PCR., Results: Here, we describe a distinct familial form of IPEX syndrome that combines autoimmune and allergic manifestations including severe enteropathy, food allergies, atopic dermatitis, hyper-IgE, and eosinophilia. We have identified a 1388-base pair deletion (g.del-6247&#95;-4859) of the FOXP3 gene encompassing a portion of an upstream noncoding exon (exon -1) and the adjacent intron (intron -1). This deletion impairs mRNA splicing, resulting in accumulation of unspliced pre-mRNA and alternatively spliced mRNA. This causes low FOXP3 mRNA levels and markedly decreased protein expression in peripheral blood lymphocytes of affected patients. Numbers of CD4(+)CD25(+)FOXP3(+) regulatory T cells are extremely low, and the CD4(+)CD25(+) T cells that are present exhibit little regulatory function., Conclusions: A new mutation within an upstream noncoding region of FOXP3 results in a variant of IPEX syndrome associating autoimmune and severe immunoallergic symptoms.
