Background: Survival of patients who were discharged from the hospital following out-of-hospital cardiac arrest (OHCA) has not been well defined.

Objective: To verify predictor variables for prognosis of patients following OHCA who survived hospitalization.

Methods: We retrospectively reviewed clinical, demographic, and outcome data of consecutive patients who were hospitalized from January 1, 2009, through December 31, 2014, into the intensive coronary care unit (ICCU) after aborted OHCA and discharged alive. The patients were followed until December 31, 2015.

Results: Of the 180 patients who were admitted into ICCU after OHCA, 64 were discharged alive (59.3%): 55 were male (85.9%), 14 died 16.5 ± 18 months after their discharge. During 1 year follow-up, nine patients (14.1%) died after a median period of 5.5 months and 55 patients (85.9 %) survived. Diabetes mellitus and chronic renal failure (CRF) were more frequent in patients who died within 1 year after their hospital discharge than those who survived. Ventricular fibrillation, such as initial arrhythmia, and opening of occluded infarct related artery were more frequent in survivors.

Conclusions: Most of the patients who were discharged after OHCA were alive at the 1 year follow-up. The risk of death of cardiac arrest survivors is greatest during the first year after discharge. CRF remains a poor long-term prognostic factor beyond the patients' discharge. Ventricular fibrillation, as initial arrhythmia, and opening of occluded infarct related artery have a positive impact on long-term survival.

Background: In 2006, the Israeli Ministry of Health distributed guidelines for improving cardiopulmonary resuscitation (CPR) knowledge among hospital staff. The impact of these guidelines on survival after in-hospital cardiac arrest (IHCA) is unclear.

Objectives: To compare rates of incidence and survival to discharge after IHCA, preceding and subsequent to issuance of the guidelines: 1995–2005 and 2006–2015.

Methods: Data were retrieved from the computerized records of patients who had an IHCA and underwent CPR. In addition, we retrieved data available from the hospital's resuscitation committee that included number, type, methods of training in CPR refresher courses, type and number of audits carried out during the past 10 years, and type of CPR quality assessments.

Results: From 1995 to 2015, IHCA incidence increased from 0.7 to 1.7 per 1000 admissions (P < 0.001), while survival rate did not increase (P = 0.37). Survival for shockable rhythms increased from 15.4 to 30.2% (P = 0.05) between the two time periods. The ratio of non-shockable to shockable rhythms increased from 2.4 to 4.6 (P = 0.01) between the two time periods.

Conclusions: Overall IHCA survival did not improve following the issuance of guidelines requiring CPR refresher courses, although survival improved for patients with initial shockable dysrhythmia. A decrease of events with initial shockable dysrhythmia, an increase with acute renal failure, and a decrease occurring in intensive care units contributed to understanding the findings. We found that CPR refresher courses were helpful, although an objective measure of their effectiveness is lacking.

Medical practice is a form of art, with each complex detail essential to the welfare of the individuals in the care of the physician. Art and medicine have shared a close relationship in a variety of ways for centuries, as demonstrated by anatomical drawings and textbooks from the 16th century. Leonardo da Vinci, driven by his fascination with the details of the human body and how it functioned, succeeded in creating an anatomical model of the cerebral ventricles and the aorta using molten wax and a glass structure, respectively (Heart and Its Blood Vessels). By using water that contained grass seeds, this experiment enabled him to study blood flow. da Vinci’s engrossment with the complexity of the human body is reflected in many of his drawings, including the famous depiction of the human physique in his drawing of the Vitruvian Man. This drawing, which defines the ideal proportions of the human body and their correlation with geometry, is an example of how artistic and scientific objectives integrate with each other.

Enthesitis is a term that refers to inflammation at tendon, ligament, or joint capsule insertions. The entheses are increasinlgly considered to be the primary site of joint inflammation in the spondyloarthropathies including psoriatic arthritis (PsA). Great advances have occurred in the understanding of enthesopathy, which has resulted in a better understanding of the etiopathogenesis of PsA. Enthesitis is difficult to assess on both clinical examination and on imaging because of the overlap in features between mechanical, degenerative, and inflammatory pathologies. Ultrasonography frequently detects entheseal abnormalities in patients with psoriasis, despite the absence of clinical symptoms of arthropathy and the longitudinal value of such lesions for PsA prediction remains unknown. The role of magnetic resonance imaging (MRI) in the assessment and monitoring of enthesitis is not fully agreed on but it is clearly superior for the assessment of spinal polyenthesitis and for diffuse peri-enthseal osteitis that can occur anywhere in the skeleton. Nuclear medicine, including conventional positron-emission tomography (PET) and high-resolution PET scan (hrPET), is more of a research tool for enthesitis and can, for example, help distinguish between PsA and osteoarthritis. Entheseal abnormalities are common in osteoarthritis, which creates diagnostic difficulty from PsA. Entheseal changes, especially on imaging, may also occur in rheumatoid arthritis (RA) and likely reflect the extension of the inflammatory process from the adjacent synovium. The nail is anatomically anchored to the skeleton via a mini-enthesis network. An association between ultrasonography determined distal interphalageal joint (DIP) extensor tendon enthesopathy and clinical nail disease was found, which highlights the pivotal role of the enthesis in this PsA risk factor. This review summarizes the relevant insights and implication of imaging for enthesitis, primarily in PsA but also in other arthropathies.

Background: Neoadjuvant chemo-radiation therapy (CRT) dosages in locally advanced non-small cell lung cancer (NSCLC) were traditionally limited to 45 Gray (Gy).

Objectives: To retrospectively analyze outcomes of patients treated with 60 Gy CRT followed by surgery.

Methods: A retrospective chart review identified patients selected for CRT to 60 Gy followed by surgery between August 2012 and April 2016. Selection for surgery was based on the extent of disease, cardiopulmonary function, and response to treatment. Pathological response after neoadjuvant CRT was scored using the modified tumor regression grading. Local control (LC), disease free survival (DFS), and overall survival (OS) were estimated by the Kaplan–Meier method.

Results: Our cohort included 52 patients: 75% (39/52) were stage IIIA. A radiation dose of 60 Gy (range 50–62Gy) was delivered in 82.7%. Surgeries performed included: lobectomy, chest-wall resection, and pneumonectomy in 67.3%, 13.4%, and 19.2%, respectively. At median follow-up of 22.4 months, the 3 year OS was 74% (95% confidence interval [CI] 52–87%), LC was 84% (95%CI 65–93), and DFS 35% (95%CI 14–59). Grade 4–5 postoperative complications were observed in 17.3% of cases and included chest wall necrosis (5.7%), bronco-pleural fistula (7.7%), and death (3.8%). A major pathologic regression with < 10% residual tumor occurred in 68.7% of patients (36/52) and showed a trend to improved OS (P = 0.1). Pneumonectomy cases had statistically worse OS (P = 0.01).

Conclusions: Major pathologic regression was observed 68.7% with 60 Gy neoadjuvant CRT with a trend to improved survival. Pneumonectomy correlated with worse survival.

Background: Anti-glomerular basement membrane (GBM) antibody disease, or Goodpasture’s disease, is the clinical manifestation of the production of anti-GBM antibodies, which causes rapidly progressive glomerulonephritis with or without pulmonary hemorrhage. Anti-GBM antibody detection is mandatory for the diagnosis of Goodpasture’s disease either from the serum or kidney biopsy. Renal biopsy is necessary for disease confirmation; however, in cases in which renal biopsy is not possible or is delayed, serum detection of anti-GBM antibody is the only way for diagnosis.

Objectives: To assess the predictive value of positive anti-GBM antibodies in a clinical setting. 

Methods: Data from anti-GBM antibody tests performed at one medical center between 2006 and 2016 were systematically and retrospectively retrieved. We recruited 1914 patients for the study. Continuous variables were computed as mean ± standard deviation, while categorical variables were recorded as percentages where appropriate. Sensitivity and specificity of anti-GBM titers were calculated. Kaplan–Meyer analysis was performed, stratifying survival according to the anti-GBM antibody titers.

Results: Of the 1914 anti-GBM test results detected, 42 were positive, 23 were borderline, 142 were excluded, and 1707 results were negative. Male-to-female ratio was 1:1.2. Sensitivity of anti-GBM test was 41.2% while specificity was 85.4%. Concerning the Kaplan–Meyer analysis, overall survival was 1163.36 ± 180.32 days (median 1058 days). 

Conclusions: Our study highlights the lack of sensitivity of serological testing of anti-GBM titers. Comparing survival curves, the survival correlated with anti-GBM titer only in a borderline way. Because highly sensitive bioassays are not routinely used in clinics, renal biopsy is still pivotal for Goodpasture’s disease diagnosis.

Background: Standardization of the dietetic care process allows for early identification of malnutrition and metabolic disorders, interdisciplinary collaboration among the medical team, and improved quality of patient care. Globally, dietitians are adopting a nutrition care model that integrates national regulations with professional scope of practice. Currently, Israel lacks a standardized dietetic care process and documentation terminology.

Objectives: To assess the utilization of a novel sectoral documentation system for nutrition care in Israel.

Methods: Seventy dietitians working in 63 geriatric facilities completed an online training program presenting the proposed patient-sectoral-model. Training was followed by submission of sample case studies from clinical practice or completion of a case simulation. Application of the proposed model was assessed by measuring the frequency participants implemented different sections of the model and responses to an approval questionnaire.

Results: Fifty-four participants (77%) provided completed cases. Over 80% of participants reported each step of the proposed dietary care process with 100% reporting the “nutrition diagnosis”. Fifty-one dietitians (72.8%) completed the approval survey with the section on nutrition diagnosis receiving a highly favorable response (95%), indicating that the new documentation system was beneficial. Over 80% of participants rated the model useful in clinical practice.

Conclusions: A sectoral approach for documenting dietetic care may be the ideal model for dietitians working in specific patient populations with the potential for improving interdisciplinary collaboration in patient care.

Background: Arthritis and arthralgia are painful symptoms experienced by many elderly patients during hospitalization. Crystal-induced arthritis (CIA) is one of the most common causes of arthritis worldwide and represents the most common cause of acute arthritis in the elderly.  

Objective: To determine the incidence of both acute new onset or acute exacerbation of CIA among elderly patients hospitalized due to an acute medical illness.

Method: This study comprised 85 patients. Patients aged 70 years and older who complained of any articular pain were included in the study. Exclusion criteria were signs of septic arthritis, chronic use of steroids or non-steroidal anti-inflammatory drugs, or admission to the hospital due to an acute attack of CIA. 

Results: Synovial aspiration was performed in 76 patients (89%). Joint aspiration yielded a diagnosis in 67 of them (79%). The predominant type of crystal was calcium pyrophosphate dehydrate (68%) followed by monosodium urate (20%). The main causes of hospitalization were acute infectious disease (57%) followed by neurologic and cardiac diseases, 14% and 9% respectively, and orthopedic problems (6%). Among patients with acute infectious disease, the main causes were pulmonary (57%) and gastrointestinal (22%) infections. In 9 patients (12%) who underwent synovial aspiration, visible crystals were identified without a definite diagnosis.

Conclusion: Our study showed that hospitalization could be a risk factor for the development of CIA, and the time to diagnose CIA is during hospitalization for other acute illnesses.

Background: Stereotactic ablative radiation therapy (SABR) is the application of a very high radiation dose to a small treatment volume. It is the new standard of care in medically inoperable early-stage lung cancer. 

Objectives: To report the outcomes of SABR in stage I lung cancer at Sheba Medical Center since its introduction in 2009.

Methods: We conducted a retrospective chart review of patients with stage I lung cancer treated during the period 2009–2015. Survival status was retrieved from the electronic medical records and confirmed with the national registry. Local failure was defined as increased FDG uptake on PETCT scan within a 2 cm radius of the treated region. Toxicity was estimated from medical records and graded according to common toxicity criteria for adverse events (CTCAE) version 4.03. Overall survival and local control were estimated by the Kaplan-Meier method.

Results: During the study period 114 patients were treated for 122 stage I lung cancer lesions. Median follow-up time was 27 months (range 8.2–69.5 months), median age was 76 years. Eighty-two percent of the tumors were stage IA (size ≤ 3 cm). Median survival was 46 months; estimated 3 year overall survival was 59% (95%CI 47–69%) and local control was 88% (95%CI 78–94%). Toxicity included chest wall pain in 8.4% of patients, rib fracture in 0.9%, grade 1–2 pneumonitis in 12%, grade 3 in 12% and grade 5 (death) in 0.9%.

Conclusions: SABR has been successfully implemented at Sheba Medical Center for the treatment of stage I lung cancer in inoperable patients. It is associated with excellent local control, minor toxicity and an acceptable overall survival.
