Background: Israel's population is diverse, with people of different religions, many of whom seek spiritual guidance during ethical dilemmas. It is paramount for healthcare providers to be familiar with different religious approaches.

Objectives: To describe the attitudes of the three major monotheistic religions when encountering four complex neonatal situations.

Methods: A questionnaire related to four simulated cases was presented to each participant: a non-viable extremely premature infant (case 1), a severely asphyxiated term infant with extensive brain damage (case 2), a small preterm infant with severe brain hemorrhage and likely extensive brain damage (case 3), and a term infant with trisomy 21 syndrome and a severe cardiac malformation (case 4).

Results: Major differences among the three religious opinions were found in the definition of viability and in the approach towards quality of life.

Conclusions: Neonatologists must be sensitive to culture and religion when dealing with major ethical issues in the neonatal intensive care unit.

Background: Although women comprise only a minority of patients hospitalized due to violence-related injury, the circumstances of attacks against women may make their injuries more severe.

Methods: We conducted a retrospective study using data of 9173 patients with stabbing-related injuries from 19 trauma centers participating in the Israeli National Trauma Registry between 1 January 1997 and 31 December 2014. Male and female patients were compared in terms of demographic and circumstantial factors, clinical characteristics, and outcomes.

Results: Women were found to have greater injury severity according to the Injury Severity Scale (ISS) – 18% vs. 11% of severe (ISS 16+) injuries – requiring more hospital resources. Injuries that contributed most to injury severity in the female population were head and severe abdominal trauma. Women also sustained injuries to more body sites than men; however, regression analysis showed that the contribution of this factor to the overall difference in injury severity was less important than the injured sites. Regression analysis among severely injured patients pointed at injury to lower extremities as an independent factor related to female mortality. Different from men, among women the stabbing injuries to the upper extremities were not a protective factor in terms of mortality.

Conclusions: There are significant differences in the injury profiles of male and female stabbing victims, which can be explained by the different circumstances of the injury event.

Background: Catheter ablation (CA) is a well-established therapeutic option for patients with recurrent symptomatic atrial fibrillation (AF). Data on gender-related differences are limited with regard to baseline characteristics and long-term success rates of catheter ablation for AF.

Methods: We analyzed a cohort of 251 consecutive patients who underwent a first catheter ablation for AF in our institute during the period 2008 through 2015. All patients were followed by regular annual clinic visits, electrocardiograms, periodic 24–48 hour Holter monitoring, and loop recorders. The primary endpoint was first recurrence of AF during 1 year of follow-up.

Results: The cohort comprised 26% women (n=65), who were older (62.1 ± 9.6 vs. 54.4 ± 11.3 years, P < 0.01) and had a higher proportion of diabetes mellitus (23.1 vs. 5.4%, P < 0.001) than male patients. No other significant differences were evident. At 1 year follow-up, the cumulative survival free of AF was significantly higher in women compared with men (83% vs. 66%, respectively, log rank P value = 0.021). Subgroup analysis showed an interaction between female and small indexed left atrial diameter (LADi < 23 mm/m²).

Conclusions: Our findings suggest that women experience a significantly lower rate of AF recurrence post-CA compared with men. This gender-related advantage appears to be restricted to women without significant left atrial enlargement. It further implies that left atrial enlargement has a stronger negative impact on post-CA AF recurrence in females than in males. Due to the relatively small sample number of females further research is warranted to validate our conclusions.

Background: The lack of organs for liver transplantation has prompted transplant professionals to study potential solutions, such as the use of livers from donors older than 70 years. This strategy is not widely accepted because potential risks of vascular and biliary complications and recurrence of hepatitis C.

Objectives: To examine the efficacy and safety of liver grafts from older donors for transplantation.

Methods: A retrospective analysis of data on 310 adults who underwent deceased donor liver transplantation between 2005 and 2015 was conducted. We compared graft and recipient survival, as well as major complications, of transplants performed with grafts from donors younger than 70 years (n=265, control group) and those older than 70 years (n=45, older-donor group), followed by multivariate analysis, to identify risk factors.

Results: There was no significant difference between the control and older-donor group at 1, 5, and 10 years of recipient survival (79.5% vs. 73.3%, 68.3% vs. 73.3%, 59.2% vs. 66.7%, respectively) or graft survival (74.0% vs. 71.0%, 62.7% vs. 71.0%, 54.8% vs. 64.5%, respectively). The rate of biliary and vascular complications was similar in both groups. Significant risk factors for graft failure were hepatitis C (hazard ratio [HR] = 1.92, 95% confidence interval [95%CI] 1.16–2.63), older donor age (HR = 1.02, 95%CI 1.007–1.031), and male gender of the recipient (HR = 1.65, 95%CI 1.06–2.55).

Conclusion: Donor age affects liver graft survival. However, grafts from donors older than 70 years may be equally safe if cold ischemia is maintained for less than 8 hours.

Background: Basal-bolus (BB) insulin treatment is increasingly used in poorly controlled diabetes patients during hospitalization and is commonly recommended at discharge; however, the extent of adherence with this recommendation is unknown.

Objectives: To determine short-term adherence of type 2 diabetes mellitus (T2DM) patients discharged from internal medicine wards with recommendation for BB insulin treatment.

Methods: Prescription (primary physician adherence) and purchase (patient adherence) of long-acting and short-acting insulins during the first month following discharge from internal medicine wards was determined in 153 T2DM patients. Adherence was defined as full if prescription/purchase of both basal (long-acting) and bolus (short-acting) insulin was completed, and as partial if only one kind of insulin (basal or bolus) was prescribed/purchased. Association between demographic and clinical parameters and adherence was determined.

Results: Full adherence with discharge instructions was higher for primary physicians than for patients )79.1% vs. 69.3%, respectively, P = 0.0182). Pre-hospitalization hemoglobin A1C was significantly associated with adherence by both patients and primary physicians (full-adherence group 9.04% ± 2.04%; no-adherence group 7.51% ± 1.35%, P = 0.002). Age was negatively associated with adherence of both primary physicians and patients; however, this association did not reach statistical significance. Patients with certain background diseases such as atrial fibrillation, coronary heart disease, and chronic heart failure had significantly worse adherence (P < 0.05). When the sole cause of admission was diabetes, full adherence (100%) of both primary physicians and patients was found.

Conclusions: Short-term adherence with discharge recommendation for BB insulin treatment is associated with pre-hospitalization patient characteristics.

Background: Unlike the elective treatment of metastatic colorectal cancer (MCRC), sufficient data and consensual guidelines on acute care are lacking.

Objectives: To analyze a cohort of MCRC patients who required urgent surgery due to acute abdomen and to identify risk factors contributing to the patient's perioperative mortality and morbidity.

Methods: A retrospective analysis was conducted of patients diagnosed with stage IV colorectal cancer who required urgent laparotomy at the Rabin Medical Center. Comparative analysis was performed using Pearson’s chi-square and Student`s t-test.

Results: Between 2010 and 2015, 113 patients underwent urgent laparotomy due to colorectal cancer complications, of which 62 patients were found to have a metastatic, stage IV, disease. Large bowel obstruction was the most common indication for urgent laparotomy. In-hospital mortality was 30% (n=19), and overall 30 day mortality was 43%. Fifteen patients (24%) required more than one surgery. The average length of hospital stay was 21 days. Age and lactate levels at presentation were the only prognostic factor found for mortality (P < 0.05).

Conclusions: MCRC laparotomy patients incur a significant burden of care and have a relatively high incidence of early mortality. Our data suggest high, verging on unacceptable, mortality and complication rates in this subgroup of patients. This finding is further accentuated in the subgroup of older patients presenting with lactatemia. These data should be considered by surgeons when discussing treatment options with patients and families.

Background: Thymectomy is a reliable surgical method for treating patients with myasthenia gravis (MG) and benign tumors of the thymus. Despite the advantages of minimally invasive surgical approaches for resection of thymic neoplasms, there are still controversies regarding the superiority of one type of surgery over another.

Objectives: To report the results of our initial Israeli experience with robotic thymectomy in 22 patients with MG and suspected benign thymic tumors.

Methods: We retrospectively analyzed 22 patients (10 men, 12 women) who underwent robotic thymectomy by a left-sided (16) or right-sided approach (6) using the da Vinci robotic system at Assaf Harofeh Medical Center. Seven patients were diagnosed with MG before surgery and 14 had suspected benign thymic neoplasms.

Results: Average operative time was 90 minutes. There were no deaths or intraoperative complications. Postoperative complications occurred in two patients (dyspnea and pleural effusion). Median blood loss was 12.3 cc (range 5–35 cc), median hospital stay 2.9 days (range 2–5 days), and mean weight of resected thymus 32.1 grams. Seven patients had thymic hyperplasia, six a lipothymoma, one a thymic cyst. Seven each had thymomas in different stages and one had a cavernous hemangioma.

Conclusions: Robotic thymectomy is a safe, technically effective surgical method for resection of thymic neoplasms. The advantages of this technique are safety, short hospitalization period, little blood loss, and low complications. We have included this surgical procedure in our thoracic surgery residency program and recommend a learning curve program of 10 to 12 procedures during residency.

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: Door-to-balloon time (DTBT) ≤ 90 minutes has become an important quality indicator in the management of ST-elevation myocardial infarction (STEMI). We identified three specific problems in the course from arrival of STEMI patients at our emergency department to initiation of balloon inflation and determined an intervention comprised of specific administrative and professional steps. The focus of the intervention was on triage within the emergency department (ED) and on increasing the efficiency and accuracy of electrocardiography interpretation.

Objectives: To examine whether our intervention reduced the proportion of patients with DTBT > 90 minutes.

Methods: We compared DTBT of patients admitted to the ED with STEMI during the year preceding and the year following implementation of the intervention.

Results: Demographic and clinical characteristics at presentation to the ED were similar for patients admitted to the ED in the year preceding and the year following intervention. The year preceding intervention, DTBT was > 90 minutes for 19/78 patients (24%). The year after intervention, DTBT was > 90 minutes for 17/102 patients (17%). For both years, the median DTBT was 1 hour. Patients with DTBT > 90 minutes tended to be older and more often female. Diagnoses in the ED were similar between those with DTBT ≤ 90 minutes and > 90 minutes. In-hospital mortality was 17% (13/78) and 14% (14/102) for the respective time periods.

Conclusions: An intervention specifically designed to address problems identified at one medical center was shown to decrease the proportion of patients with DTBT > 90 minutes.
