Background: Trabectedin is a marine-derived chemotherapy, which has received U.S. Food and Drug Administration approval for use in anthracycline-resistant advanced soft tissue sarcoma (STS), especially liposarcoma and leiomyosarcoma (L-sarcomas).

Objectives: To describe our 10 year real-life experience with trabectedin regarding safety and efficacy in a cohort of 86 patients.

Methods: In our study cohort, 46.51% were diagnosed with liposarcoma and 43.02% with leiomyosarcoma. A total of 703 cycles of trabectedin were given, with a median of five cycles per patient (range 1–59). Median overall survival was 13.5 months for the whole cohort, 11 months for liposarcoma patients (range 1–63), and 15 months for leiomyosarcoma patients (range 1–35).

Results: There was no statistically significant difference in progression free survival when stratified according to previous treatment lines given. Trabectedin exhibited a favorable safety profile, with only 22% requiring dose reductions. Grade 3 and higher toxicity was noted in 25% of the patients, mostly due to myelosuppression. There were no treatment-related deaths.

Conclusions: Trabectedin is a safe and effective drug for treating advanced STS. Our results reflect real-life data with patients receiving the drug as a third and even fourth line of treatment, or with a suboptimal performance status, yet achieving impressive clinical benefit rates and survival.

Background: Sepsis is a common cause of hospitalization, particularly in intensive care units (ICUs), and is a major cause of morbidity and mortality. Diagnosis is often difficult due to the absence of characteristic clinical signs (e.g., fever and leukocytosis); therefore, additional markers, in addition to C-reactive protein (CRP) and white blood cell (WBC) count, are needed.

Objectives: To prospectively link resting energy expenditure (REE) with CRP, WBC count, and sequential organ failure assessment (SOFA) scores in ICU patients. Such a correlation may suggest REE measurement as an additional parameter for sepsis diagnosis.

Methods: Our study comprised 41 ventilated consecutive patients > 18 years of age. Patient demographic data, height, actual body weight, and SOFA scores were collected at admission. REE was measured by indirect calorimetry. REE, CRP, and WBC measurements were collected at admission, on day three after admission, and 1 week later or as clinically indicated.

Results: Comparison of the REE and CRP changes revealed a significant correlation between REE and CRP changes (r = 0.422, P = 0.007). In addition, CRP changes also correlated with the changes in REE (r = 0.36, P = 0.02). Although no significant correlations in REE, WBC count, and SOFA score were found, a significant trend was observed.

Conclusions: To the best of our knowledge, this is the first study to link REE and CRP levels, indicative of severe infection. Further study is needed to establish these findings.

Background: Contemporary data on clinical profiles and long-term outcomes of young adults with coronary artery disease (CAD) are limited.

Objectives: To determine the risk profile, presentation, and outcomes of young adults undergoing coronary angiography.

Methods: A retrospective analysis (2000–2017) of patients aged ≤ 35 years undergoing angiography for evaluation and/or treatment of CAD was conducted.

Results: Coronary angiography was performed in 108 patients (88% males): 67 acute coronary syndrome (ACS) and 41 non-ACS chest pain syndromes. Risk factors were similar: dyslipidemia (69%), positive family history (64%), smoking (61%), obesity (39%), hypertension (32%), and diabetes (22%). Eight of the ACS patients (12%) and 29 of the non-ACS (71%) had normal coronary arteries without subsequent cardiac events. Of the 71 with angiographic evidence of CAD, long-term outcomes (114 ± 60 months) were similar in ACS compared to non-ACS presentations: revascularization 41% vs. 58%, myocardial infarction 32% vs. 33%, and all-cause death 8.5% vs. 8.3%. Familial hypercholesterolemia (FH) was diagnosed in 25% of those with CAD, with higher rates of myocardial infarction (adjusted hazard ratio [HR] 2.62, 95% confidence interval [95%CI] 1.15–5.99) and revascularization (HR 4.30, 95%CI 2.01–9.18) during follow-up. Only 17% of patients with CAD attained a low-density lipoprotein cholesterol treatment goal < 70 mg/dl.

Conclusions: CAD in young adults is associated with marked burden of traditional risk factors and high rates of future adverse cardiac events, regardless of acuity of presentation, especially in patients with FH, emphasizing the importance of detecting cardiovascular risk factors and addressing atherosclerosis at young age.

Background: Recent studies have suggested that urgent cholecystectomy is the preferred treatment for acute cholecystitis. However, initial conservative treatment followed by delayed elective surgery is still common practice in many medical centers.

Objectives: To determine the effect of percutaneous cholecystostomy on surgical outcome in patients undergoing delayed elective cholecystectomy.

Methods: We conducted a retrospective analysis of all patients admitted to our medical center with acute cholecystitis who were treated by conservative treatment followed by delayed cholecystectomy between 2004 and 2013. Logistic regression was calculated to assess the association of percutaneous cholecystostomy with patient characteristics, planned surgical procedure, and the clinical and surgical outcomes.

Results: We identified 370 patients. Of these, 134 patients (36%) underwent cholecystostomy during the conservative treatment period. Patients who underwent cholecystostomy were older and at higher risk for surgery. Laparoscopic cholecystectomy was offered to 92% of all patients, yet assignment to the open surgical approach was more common in the cholecystostomy group (16% vs. 3%). Cholecystostomy was associated with significantly higher conversion rates to open approach (26% vs. 13%) but was not associated with longer operative time, hemorrhage, surgical infections, or bile duct or organ injuries.

Conclusions: Treatment with cholecystostomy is associated with higher conversion rates but does not include other major operative-related complications or poorer clinical outcome.

Background: Patients with rheumatic diseases, such as rheumatoid arthritis (RA) and ankylosing spondylitis (AS), encounter significantly higher rates of cardiovascular morbidity and mortality. The renin-angiotensin-aldosterone system maintains hemodynamic stability through blood pressure regulation. When dysregulated, this system has been implicated in various pathological conditions, including cardiovascular events.

Objectives: To investigate the levels of renin and aldosterone in RA and AS patients.

Methods: Three groups were recruited: patients with RA, patients with AS, and healthy controls. Subjects were excluded if they had a diagnosis of hypertension, hyperaldosteronism, or renal artery stenosis, or were taking drugs that might have affected renin levels. Renin and aldosterone levels were measured using commercially available kits. Data were analyzed using univariate analyses and multivariate regression analyses.

Results: Fifty-one subjects were enrolled in the study: 15 with RA, 4 with AS, and 32 healthy controls. At the univariate analysis, the three groups differed in age (P = 0.005), renin levels (P = 0.013), and aldosterone-to-renin ratio (P = 0.019). At the post-hoc tests, both AS and RA patients differed from controls for renin levels and the aldosterone-to-renin ratio. At the multivariate regression analysis, AS patients had lower renin values than controls (beta standardized regression coefficient -0.323, P = 0.022).

Conclusion: Patients with RA tended to have lower levels of plasma renin compared to healthy subjects. This finding indicates that the renin-angiotensin-aldosterone system might not be directly involved in the process that results in increased cardiovascular events in rheumatoid arthritis.

Background: Pacemaker pocket early post-implantation inflammation (EPII) is defined as clinical signs of local erythema without any systemic signs of infection occurring early after implantation. Data on the best treatment regimen for apparent superficial EPII is scarce. 

Objectives: To investigate the prognostic value of medical treatment, rather than extraction surgery, in patients with EPII. 

Methods: Data from 6013 consecutive patients who underwent cardiac implantable electronic device (CIED) implantation or replacement from 2007–2015 were retrospectively analyzed; 40 (0.7%) presented with EPII. Our goal was the absence of major complications and to avoidance of extraction. 

Results: Patients with EPII were initially treated medically. Nineteen (47%) (group A) recovered with antibiotic treatment only. In the other 21 patients (53%) (group B), CIED extraction was performed. Group B had more major complications compared to group A (15 [71%] vs. 0 [0%], P < 0.001). The only significant difference in baseline characteristics was history of non-initial procedure. While 86% of group B patients had a previous non-initial procedure, only 53% of group A patients underwent previous replacement (P < 0.05). In multivariate analysis, previous non-initial procedure was the only predictor for need of extraction at 1 year, hazard ratio 3.5, 95% confidence interval 1.001–11.73, P < 0.05.

Conclusions: Conservative treatment in patients with EPII after non-initial procedure can lead to serious adverse events resulting in the need for extraction. Close follow-up and aggressive treatment should be considered early in the therapeutic course.

Background: There is scant research on the psychopathology of Israeli soldiers who present to a general hospital emergency department (ED).

Objectives: To assess the psychopathology among a cohort of Israeli soldiers who presented to a general hospital ED for mental health assessment.

Methods: The demographic and clinical characteristics of 124 consecutive soldiers who presented to the ED for psychiatric assessment between January 2008 and September 2012 were reviewed. Twenty-seven soldiers from the cohort were contacted for follow-up by telephone on average 52 months later.

Results: The reasons for presentation to the ED, usually during the early stages of military service, included self-harming behavior, suicidal ideation, somatoform complaints, and dissatisfaction with their military service. Psychiatric diagnoses included adjustment disorder and personality disorder. Self-harming behavior/suicidal ideation was significantly correlated with unspecified adjustment disorder (P = 0.02) and personality disorder (P = 0.001). At follow-up, there was a lack of substantial psychopathology: none of the subjects engaged in self-harming behavior/suicidal ideation and a consistent trend was observed toward clinical improvement.

Conclusions: Psychiatric intervention of soldiers who present to a general hospital ED because of emotional difficulties may provide the opportunity for crisis intervention and validation of the soldier's distress. To the best of our knowledge this is the first Israeli study of psychopathology among soldiers who presented to an ED.
