Background: With the widespread use of antifungal agents, the frequency of non-albicans Candida (NAC) blood-stream infections (BSI) is increasing.

Objectives: To describe the epidemiology, clinical manifestations, and risk factors for NAC BSI, focusing on prior antifungal and immunosuppressive therapy.

Methods: The authors conducted an observational, retrospective cohort study among adult patients with candidemia at the Rambam Health Care Campus, a tertiary medical center in Israel, between 2009 and 2015. Comparisons between patients with Candidemia albicans and NAC candidemia were performed. Regression analysis, with NAC BSI as the dependent variable and significant risk factors for NAC as independent variables, was performed.

Results: A total of 308 episodes of candidemia were included. C. albicans was isolated in 30.8% of patients (95/308), while NAC spp. were isolated in the rest. Significant independent risk factors for NAC included immunosuppression therapy (odds ratio [OR] 0.38, 95% confidence interval [95%CI] 0.19–0.76) and previous azole use (OR 0.2, 95%CI 0.06–0.710). The interaction between prior azole and immunosuppression therapy in the model was not significant, and after its inclusion in the model only immunosuppression remained significantly associated with NAC. In the subgroup of patients who did not receive prior azoles, immunosuppression therapy, neutropenia, and bone marrow transplantation were significantly associated with NAC.

Conclusions: Independent of previous azole treatment, immunosuppressive therapy was a significant risk factor for NAC in our cohort.

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: Access-site bleeding is a common complication of transfemoral transcatheter aortic valve implantation (TAVI). Percutaneous stent-graft implantation within the femoral artery may achieve hemostasis and avert the need for more invasive surgical vascular repair; however, failure to advance a guidewire antegradely via the injured vessel may preclude stent delivery. While retrograde stent-graft delivery from the distal vasculature may potentially enable percutaneous control of bleeding, this approach has not been reported.

Objectives: To assess the feasibility of a retrograde approach for stent-graft implantation in the treatment of access-site bleeding following transfemoral TAVI.

Methods: A prospective TAVI registry was analyzed. Of 349 patients who underwent TAVI, transfemoral access was used in 332 (95%). Access-site injury requiring stent-graft implantation occurred in 56 (17%). In four patients (7%), antegrade wiring across the site of vascular injury was not possible and a retrograde approach for stent delivery was used.

Results: Distal vascular access was achieved via the superficial femoral or profunda artery. Retrograde advancement of a polymer-coated 0.035” wire to the abdominal aorta, followed by stent-graft delivery to the common femoral artery, achieved hemostasis in all cases. During a median (interquartile range) follow-up period of 198 (618) days (range 46–2455) there were no deaths and no patient required additional vascular interventions.

Conclusions: A retrograde approach for stent-graft delivery is feasible and allows percutaneous treatment of a common femoral artery injury following TAVI in patients who are not suitable for the conventional antegrade approach.

Background: Pulmonary rehabilitation has shown significant benefit for patients with chronic obstructive pulmonary disease (COPD). The effect on non-COPD pulmonary patients is less well established.

Objectives: To determine whether pulmonary rehabilitation is also beneficial for non-COPD pulmonary patients.

Methods: Clinical and demographic data on non-COPD pulmonary patients who participated in our institutional pulmonary rehabilitation program between January 2009 and December 2016 were collected. Participants engaged in a 60-minute, twice-weekly, ambulatory hospital-based program lasting 12 to 24 sessions. Sessions included both endurance and muscle training as well as healthy lifestyle educational activities. The six-minute walk test (6MWT) and the St. George's Respiratory Questionnaire (SGRQ) were conducted before and after the rehabilitation program.

Result: We recruited 214 non-COPD patients, of whom 153 completed at least 12 sessions. Of these, 59 presented with interstitial lung disease (ILD), 18 with non-ILD restrictive lung defects, 25 with asthma, 30 with lung cancer, and 21 with other conditions (e.g., pulmonary hypertension, bronchiectasis) The groups demonstrated significant improvement in 6MWT and in SGRQ scores. Non-COPD patients gained a 61.9 meter (19%) improvement in the 6MWT (P < 0.0001) and 8.3 point reduction in their SGRQ score (P < 0.0001).

Conclusions: Pulmonary rehabilitation is effective in non-COPD pulmonary patients. As such, it should be an integral part of the treatment armament provided to the vast majority of those suffering from chronic respiratory disease.

Background: Selective management of stable patients with anterior abdomen stab wounds (AASWs) has become a gold standard management approach throughout the world. Evidenced-based options for supporting selective management include clinical follow-up, local wound exploration with or without diagnostic peritoneal lavage, diagnostic laparoscopy, and abdominal computerized tomography. The presence of multiple AASWs might signify a more aggressive attack and limit the safety of a selective management approach.

Objectives: To evaluate whether multiple AASWs are associated with an increased risk of intra-abdominal injury requiring emergency surgery.

Methods: We retrospectively reviewed all AASW patients admitted to Assaf Harofeh Medical Center, Zerifin, Israel, and Hillel Yaffe Medical Center in Hadera, Israel, from 2007 to 2015. Patients were divided into two groups based on the number of stab wounds: single or multiple. Data were coded for demographics, severity of injury, presence of intra-abdominal injury, laparotomy rate, length of hospital stay (LOS), length of stay in the intensive care unit (LICU), and survival.

Results: The study included 169 patients. Of these, 143 patients had a single AASW and 26 had multiple AASWs. There were no differences between the groups regarding demographics, severity of injury, intra-abdominal penetration, specific organ injury, LOS, or LICU. There was no difference in the percentage of patients requiring laparotomy. The overall mortality was 2.36% (4/169). There was no significant difference in the mortality rate between the groups (P = 0.11).

Conclusions: The presence of multiple AASWs is not a risk factor for increased frequency and severity of intra-abdominal injury.

Background: The prevalence of Helicobacter pylori varies geographically by age, race, and socioeconomic status (SES). However, the impact of ethnicity on endoscopic outcomes in infected individuals is not well known.

Objectives: To assess the impact of ethnicity among Israelis with biopsy-proven H. pylori infection.

Methods: A retrospective study, including patients who underwent gastroscopy and were diagnosed histologically with H. pylori infection, was conducted. Information on demographics, SES, medications, and co-morbidities were extracted from medical records. Univariate (Student's t-test, chi-square test) and multivariate (multinomial and logistic) regression analysis were conducted to examine the predictors of the clinical outcome.

Results: The study included 100 Israeli Jews and 100 Israeli Arabs diagnosed with biopsy-proven H. pylori infection. At univariate analysis, the number of households was higher among Arabs (P < 0.001), whose family income and parental education were lower than among Jews (P < 0.001 for both variables). The response to amoxicillin and clarithromycin differed between the two groups, being higher among Jews (P < 0.001).In clinical outcomes (gastritis severity, gastric and duodenal ulcer, intestinal metaplasia, atrophic gastritis, and MALT), no statistically significant differences could be detected between Jews and Arabs. Concerning intestinal metaplasia, lack of consumption of nonsteroidal anti-inflammatory drugs resulted a statistically significant protective factor (odds ratio 0.128, 95% confidence interval 0.024–0.685, P = 0.016).

Conclusions: Although in the literature ethnicity seems to be a risk factor for H. pylori colonization, no statistical significance was detected in various endoscopic and histological findings related to H. Pylori infection between Israeli Arabs and Jews.

Angiogenesis is the outgrowth of new blood vessels from existing ones and is an early occurrence in inflamed joint tissue. It is governed by a tightly controlled balance of pro- and anti-angiogenic stimuli, which promote or inhibit generation and proliferation of new endothelial cells, vascular morphogenesis, and vessel remodeling. At the beginning, capillary formation is crucial in maintaining the supply of various nutrients as well as oxygen to the inflamed tissue. Local and systemic expression of angiogenic factors may indicate a constant remodeling of synovial vasculature. Redox signaling is closely related to angiogenesis and can alter angiogenic responses of synovial cells. In this review we discuss key issues about the endothelial pathology in inflammatory arthritis followed by a review of angiogenic processes and main angiogenic mediators. We discuss the hypoxia-vascular endothelial growth factor (VEGF)-Ang/Tie2 system and its related therapeutic implications in detail with further review of various mediator protein targets and intracellular regulatory pathway targets with their current and potential future role in preclinical or clinical setting whilst ameliorating inflammation.

Throughout history, studies on episodes of famine have led to the discovery of metabolic abnormalities and hormonal aberrations as well as an increased incidence of cancer and mental health conditions. Starvation during early life is thought to nfluence the programming of childhood and adult bone metabolism, which may result in poor bone health in later life. This observational case series includes a small group (with no control group) of famine-exposed Holocaust survivors and their descendants. We proposed an investigational mechanism to determine any association between starvation and osteoporosis, both in the individual survivors and in their descendants.

Background: Kidney transplantation is associated with early improvement in cardiac function and structure; however, data on cardiac adaptation and its relation to kidney allograft function remain sparse.

Objectives: To investigate the relationship between post-transplant kidney function and echocardiographic measures in patients with normal/preserved pre-transplant cardiac structure and function.

Methods: The study included 113 patients who underwent kidney transplantation at a single tertiary medical center from 2000 to 2012. The patients were evaluated by echocardiography before and after transplantation, and the relation between allograft function and echocardiographic changes was evaluated. Echocardiography was performed at a median of 510 days after transplantation.

Results: The post-transplantation estimated glomerular filtration rate (eGFR) was directly correlated with left ventricular (LV) systolic function and inversely correlated with LV dimensions, LV wall thickness, left atrial diameter, and estimated systolic pulmonary arterial pressure. In patients with significant allograft dysfunction (eGFR ≤ 45 ml/min), LV hypertrophy worsened, with no improvement in LV dimensions. In contrast, in patients with preserved kidney function, there was a significant reduction in both LV diameter and arterial pulmonary systolic pressure.

Conclusions: Our results show that in kidney transplant recipients, allograft function significantly affects cardiac structure and function. Periodic echocardiographic follow-up is advisable, especially in patients with kidney graft dysfunction.
