Background: Fibromyalgia syndrome (FMS) is a chronic disorder characterized by widespread musculoskeletal pain accompanied by various additional symptoms. The prevalence of FMS ranges between 2–8% of the population. The exact pathophysiology of the disease remains unknown, and under certain circumstances it is difficult for the physician to diagnose. Previous studies have shown a correlation between inflammatory biomarkers such as C-reactive protein (CRP) and FMS activity, suggesting that an inflammatory component may play a role in this disease pathogenesis.

Objectives: To investigate the role of certain new inflammatory biomarkers in the diagnosis of patients with FMS.

Methods: In this study data were collected from FMS patients who were admitted to Ziv Medical Center during the period 2013 to 2019 in an attempt to find a connection between inflammatory markers detectable by a traditional complete blood count (CBC) tests such as neutrophil-lymphocytes ratio (NLR), platelet-lymphocyte ratio (PLR), mean platelet value (MPV), red cell distribution width (RDW), and C-reactive protein (CRP) and FMS.

Results: We found significantly higher CRP levels, MPV, and PLR and lower lymphocyte count in the FMS group compared to the control group.

Conclusions: FMS has certain inflammatory components that may be useful in disease diagnosis

Background: Cardiovascular disease (CVD) is more frequent in patients with systemic lupus erythematosus (SLE) compared with age- and sex-matched healthy subjects. SLE is an autoimmune disease that is more prevalent in women (9:1). Women tend to develop CVD in post-menopausal years; however, women with SLE may develop endothelial dysfunction and CVD at a younger age in the pre-menopausal years.

Objectives: To study the endothelial function of adult-onset SLE patients from the north of Israel (the Galilee region) and to determine whether modern management (including biological treatments) changes the risk of developing CVD.

Methods: Thirteen females with adult-onset SLE without renal involvement were recruited to this prospective study. Clinical parameters (age, height, body mass index [BMI]), laboratory parameters (C-reactive protein [CRP] and hemoglobin level), and vascular responsiveness (flow mediated diameter percent change [FMD%]) were evaluated and compared to 11 age-matched healthy females. Student's t-test was used to find differences between the two groups.

Results: No difference was observed in adult-onset SLE female patients and their age- and sex-matched controls with regard to age (42.1 ± 11.8 years vs. 36.6 ± 10.8 years, P = NS), BMI (25 ± 1.8 kg/m² vs. 25 ± 2.5 kg/m², P = NS), and hemoglobin level (11.9 ± 0.9 gr% vs. 12.7 ± 1.2 gr%, P = NS). However, a significant difference was found in CRP (2.57 ± 2.2 mg vs. 0.60 ± 0.37 mg, P = 0.001), vascular responsiveness (0.94 ± 6.6 FMD% vs. 9.2 ± 8.1 FMD%, P = 0.012), and height (165.7 ± 4.5 cm vs. 171.6 ± 5.8 cm, P = 0.009).

Conclusions: Adult-onset SLE females had impaired endothelial function even though they were treated by modern protocols.

Inflammation is the basic mechanism leading to many pathological processes, including degenerative diseases, atherosclerosis, and cancer. We found an interesting link connecting rheumatoid arthritis and atherosclerosis that may explain the high cardiovascular event rate among patients with rheumatoid arthritis, but also may lead to a new way of thinking and a better understanding of atherosclerosis. Rheumatoid arthritis could serve as a model of accelerated atherosclerosis. Understanding the basic mechanisms of rheumatoid arthritis may solve some of the complexity of atherosclerosis.

Background: Ureaplasma species (Usp) are the most prevalent genital Mycoplasma isolated from the urogenital tract of both men and women. Usp may be commensals in the genital tract but may also be contributors to a number of pathological conditions of the genital tract. Because they can also just colonize the genital tract of healthy people, their pathogenic role can be difficult to prove.

Objectives: The aim of the study was to evaluate the efficacy of a quantitative polymerase chain reaction (qPCR) method for the discrimination between infection and colonization by measuring prevalence of Usp in asymptomatic versus symptomatic patients.

Methods: Urine samples were tested for U. parvum and U. urealyticum using a semi-quantitative multiplex PCR technique for sexually transmitted diseases (Anyplex™ STI-7 Detection Kit, Seegene, South Korea). A total of 250 symptomatic and 250 asymptomatic controls were included.

Results: A strong positive result for U. parvum was significantly more prevalent in symptomatic compared to asymptomatic patients. This finding was observed especially in women and in the young group (15–35 years of age). No significant differences were observed between the prevalence in symptomatic and asymptomatic patients of U. parvum with low strength of positivity and for U. urealyticum in all groups by age, gender, and strength of positivity.

Conclusions: The significant difference between the symptomatic and asymptomatic group in the highest positivity group for U. parvum using the Anyplex™ STI-7 detection kit in urine may indicate a high probability of infection rather than colonization, especially in women and young patients.

Background: Outcomes of patients with acute ST-elevation myocardial infarction (STEMI) are strongly correlated to the time interval from hospital entry to primary percutaneous coronary intervention (PPCI). Current guidelines recommend a door to balloon time of < 90 minutes. 

Objectives: To reduce the time from hospital admission to PPCI and to increase the proportion of patients treated within 90 minutes. 

Methods: In March 2013 the authors launched a seven-component intervention program: 

1. Direct patient evacuation by out-of-hospital emergency medical services to the coronary intensive care unit or catheterization laboratory


2. Education program for the emergency department staff


3. Dissemination of information regarding the urgency of the PPCI decision


4. Activation of the catheterization team by a single phone call


5. Reimbursement for transportation costs to on-call staff who use their own cars


6. Improvement in the quality of medical records


7. Investigation of failed cases and feedback 

Results: During the 14 months prior to the intervention, initiation of catheterization occurred within 90 minutes of hospital arrival in 88/133 patients(65%); during the 18 months following the start of the intervention, the rate was 181/200 (90%) (P < 0.01). The respective mean/median times to treatment were 126/67 minutes and 52/47 minutes (P < 0.01). Intervention also resulted in shortening of the time interval from hospital entry to PPCI on nights and weekends. 

Conclusions: Following implementation of a comprehensive intervention, the time from hospital admission to PPCI of STEMI patients shortened significantly, as did the proportion of patients treated within 90 minutes of hospital arrival. 

 

Background: Radial artery occlusion (RAO) may occur following transradial catheterization, precluding future use of the vessel for vascular access or as a coronary bypass graft. Recanalization of RAO may occur; however, long-term radial artery patency when revascularization is more likely to be required has not been investigated. Transradial catheterization is usually performed via 5-Fr or 6-Fr catheters. Insertion of 7-Fr sheaths into the radial artery enables complex coronary interventions but may increase the risk of RAO. 

Objective: To assess the long-term radial artery patency following transradial catheterization via 7-Fr sheaths.

Methods: Antegrade radial artery blood flow was assessed by duplex-ultrasound in 43 patients who had undergone transradial catheterization via a 7-Fr sheath. 

Results: All patients had received intravenous unfractionated heparin with a mean activated clotting time (ACT) of 247 ± 56 seconds. Twenty-four patients (56%) had received a glycoprotein IIbIIIa inhibitor and no vascular site complications had occurred. Mean time interval from catheterization to duplex-ultrasound was 507 ± 317 days. Asymptomatic RAO was documented in 8 subjects (19%). Reduced body weight was the only significant univariate predictor of RAO (78 ± 11 vs. 89 ± 13 kg, P = 0.031). In a bivariate model using receiver operator characteristic (ROC) curves, the combination of lower weight and shorter ACT offered best prediction of RAO (area under the ROC curve 0.813). 

Conclusions: Asymptomatic RAO was found at late follow-up in approximately 1 of 5 patients undergoing transradial catheterization via a 7-Fr sheath and was associated with lower body weight and shorter ACT. 

 

Background: Echocardiographic ventricular function predicts prognosis and guides management in patients with acute coronary syndromes. In elderly patients, interpretation of echocardiographic measurements may be difficult, especially regarding assessment of diastolic left ventricular function.

Objectives: To examine the usefulness of echocardiographic systolic and echocardiographic diastolic LV[1] function measurements as predictors of long-term outcome in elderly patients with ACS[2].

Methods: We studied 142 consecutive elderly patients (≥ 70 years old, mean age 80 ± 6 years) with ACS who had an echocardiogram at index hospitalization and were in sinus rhythm. LV ejection fraction and diastolic mitral inflow pattern were examined as predictors of survival and repeat hospitalization over a period of 18–24 months.

Results: During the 2 year mean follow-up period 35/142 patients died (25%). Survival was lower in patients with EF[3] < 40% (n=42) as compared to EF ≥ 40% (n=100) (2 year survival rate 61% vs. 81%, P = 0.038). Patients with severe diastolic dysfunction (a restrictive LV filling pattern, n=7) had a lower survival rate than those without (43 vs. 76%, P = 0.009). The most powerful independent predictor of mortality was a restrictive filling pattern (hazard ratio 4.6, 95% confidence interval 1.6–13.5), followed by a clinical diagnosis of heart failure on admission and older age. Rate of survival free of repeat hospitalization was low (33% at 18 months) but repeat hospitalization was not predicted either by EF or by a restrictive filling pattern.

Conclusions: As in the young, echocardiographic measurements of systolic and diastolic LV function predicted long-term survival in elderly patients with ACS. A restrictive filling pattern was the strongest independent predictor of mortality.
