Background: The prognosis of long-term clinical outcomes for each patient is of utmost importance., Objectives: To evaluate the association between rates of family attendance during rounds and long-term outcomes., Methods: We conducted a historic cohort study., Results: We followed 200 consecutive patients for a median of 19 months. Within the group of patients that had family members present in > 75% of rounds, the 30-day re-hospitalization rate was tenfold higher (P = 0.017). The overall prognosis (including median survival length) of patients who had the highest rates of family attendance (> 75%) was significantly worse compared to patients who had lower rates (P = 0.028). High rates of family attendance were found to correlate with other established risk factors for long-term mortality, including advanced age (r = 0.231, P = 0.001) and in-hospital delirium., Conclusions: High family attendance during physician rounds in an internal medicine department is associated with worse patient prognosis.

Background: Ferritin, the cellular protein storage for iron, has emerged as a key molecule in the immune system, orchestrating the cellular defense against inflammation. At the end of 2019, the novel severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) rapidly spread throughout China and other countries around the world, resulting in a viral pandemic., Objectives: To evaluate the correlation between ferritin and disease severity in coronavirus disease-2019 (COVID-19)., Methods: In this cross-sectional study, we obtained clinical and laboratory data regarding 39 hospitalized patients with confirmed COVID-19 from two hospitals in Israel., Results: A significant increase in ferritin levels was demonstrated in patients with moderate and severe disease, compared to patients with mild disease (P = 0.006 and 0.005, respectively). Severe patients had significantly higher levels of ferritin (2817.6 ng/ml) than non-severe patients (708.6 ng/ml) P = 0.02., Conclusions: In this preliminary cross-sectional study, elevated ferritin levels were shown to correlate with disease severity in 39 patients from Israel with confirmed COVID-19 infection. Our results further strengthen the hypothesis that severe COVID-19 disease might be due to an underlying dysregulated hyperimmune response. In order to identify these patients early and prioritized resources, we believe that all patients with COVID-19 should be screened for hyperferritinemia.

Background: In February 2020, the World Health Organisation designated the name COVID-19 for a clinical condition caused by a virus identified as a cause for a cluster of pneumonia cases in Wuhan, China. The virus subsequently spread worldwide, causing havoc to medical systems and paralyzing global economies. The first COVID-19 patient in Israel was diagnosed on 27 February 2020., Objectives: To present our findings and experiences as the first and largest center for COVID-19 patients in Israel., Methods: The current analysis included all COVID-19 patients treated in Sheba Medical Center from February 2020 to April 2020. Clinical, laboratory, and epidemiological data gathered during their hospitalization are presented., Results: Our 162 patient cohort included mostly adult (mean age of 52 ± 20 years) males (65%). Patients classified as severe COVID-19 were significantly older and had higher prevalence of arterial hypertension and diabetes. They also had significantly higher white blood cell counts, absolute neutrophil counts, and lactate dehydrogenase. Low folic acid blood levels were more common amongst severe patients (18.2 vs. 12.9 vs. 9.8, P = 0.014). The rate of immune compromised patients (12%) in our cohort was also higher than in the general population. The rate of deterioration from moderate to severe disease was high: 9% necessitated non-invasive oxygenation and 15% were intubated and mechanically ventilated. The mortality rate was 3.1., Conclusions: COVID-19 patients present a challenge for healthcare professionals and the whole medical system. We hope our findings will assist other providers and institutions in their care for these patients.

Background: Pericardial biopsies are rarely performed during the diagnosis and management of pericardial diseases. The circumstances and clinical profile of patients undergoing pericardial biopsies are largely uncharacterized., Objectives: To examine the circumstances in which pericardial biopsies are obtained and to evaluate their diagnostic yield., Methods: We studied a total of 100 cases (71% males, mean age 60.8 years, range 8.1-84.5 years) of surgically resected pericardium specimens obtained from 2000 to 2015 at Sheba Medical Center, the largest medical center in Israel. Patients were classified into groups according to four major histological etiologies: idiopathic pericarditis, constrictive pericarditis, malignant pericarditis, and post-cardiac injury syndrome (PCIS). The clinical history and course, laboratory, echocardiography, and histological results were reviewed retrospectively., Results: Causes of pericarditis according to histological definitions included idiopathic pericarditis (29%), constrictive pericarditis (29%), PCIS (9%), and malignant pericarditis (26%). Overall sensitivity of the pericardial biopsy in patients with malignancy was 57.7%. During the study period, we found a trend toward an increased number of biopsies due to constrictive pericarditis and PCIS, along with a decrease in the number of biopsies performed in patients with malignant or idiopathic pericarditis. The diagnosis following biopsy did not change for any of the patients., Conclusions: Our findings suggest a low diagnostic yield from pericardial biopsies, especially in malignant pericarditis. This conclusion, along with novel therapies, resulted in the infrequent use of pericardial biopsy in recent years.

Background: Accurate pulse oximetry reading at hospital admission is of utmost importance, mainly for patients presenting with hypoxemia. Nevertheless, there is no accepted or evidence-based protocol for such structured measuring., Objectives: To devise and assess a structured protocol intended to increase the accuracy of pulse oximetry measurement at hospital admission., Methods: The authors performed a prospective comparison of protocol-based pulse-oximetry measurement with non-protocol based readings in consecutive patients at hospital admission. They also calculated the relative percentage of improvement for each patient (before and after protocol implementation) as a fraction of the change in peripheral capillary oxygen saturation (SpO2) from 100%., Results: A total of 460 patients were recruited during a 6 month period. Implementation of a structured measurement protocol significantly changed saturation values. The SpO2 values of 24.7% of all study participants increased after protocol implementation (ranging from 1% to 21% increase in SpO2 values). Among hypoxemic patients (initial SpO2 < 90%), protocol implementation had a greater impact on final SpO2 measurements, increasing their median SpO2 readings by 4% (3-8% interquartile range; P < 0.05). Among this study population, 50% of the cohort improved by 17% of their overall potential and 25% improved by 50% of their overall improvement potential. As for patients presenting with hypoxemia, the median improvement was 31% of their overall SpO2 potential., Conclusions: Structured, protocol based pulse-oximetry may improve measurement accuracy and reliability. The authors suggest that implementation of such protocols may improve the management of hypoxemic patients.

Background: Patients with giant cell arteritis (GCA) suffer from inflammatory diseases often treated by large amounts of corticosteroids. Whether this inflammatory burden also carries an increased risk for cardiovascular morbidity, and especially ischemic heart disease, is not clearly established., Objectives: To clarify the linkage between GCA and ischemic heart disease., Methods: In a cross-sectional study, we assessed the association between GCA and ischemic heart disease, adjusting for cardiovascular risk factors, among GCA patients and matched controls using the database of the largest healthcare provider in Israel., Results: The study group was comprised of 5659 GCA patients and 28,261 age and gender matched controls. The proportion of ischemic heart disease was higher in the GCA group (27.5% vs. 12.5% among controls, odds ratio 2.65). Diabetes mellitus, hypertension, hyperlipidemia and smoking were also found to have higher concurrency in GCA. After stratifying for those cardiovascular co-morbidities using logistic regression, GCA remained independently associated with ischemic heart disease with an odds ratio of 1.247 (1.146-1.357 P < 0.001)., Conclusions: GCA is associated with both cardiovascular risk factors and ischemic heart disease. Healthcare professionals should not overlook this aspect of the disease when managing GCA patients.

Background: Predicting mortality is important in treatment planning and professional duty towards patients and their families., Objectives: To evaluate the predictive value regarding patients' survival once the diagnosis of "general deterioration" replaces an ICD-9 diagnosis upon re-admission., Methods: In this retrospective cohort case-control study, we screened the records of patients re-admitted at least three times during the past 2 years. For each patient's death during the third hospitalization, we matched (for age and gender) a patient who survived the third hospitalization. We evaluated 14 parameters potentially accountable for increased risk of mortality, e.g., length of stay at each admission, interval to re-admission, etc. We applied a multifactorial analysis using logistic regression to predict the risk of mortality during the third hospitalization as potentially affected by the aforementioned parameters., Results: The study included 81 study patients and 81 controls. Of the 14 parameters potentially explaining an increased risk of mortality during the third hospitalization, several were found to be statistically significant. The most significant was the diagnostic switch from a specific ICD-9 diagnosis on first admission to the non-specific diagnosis of "general deterioration" at the second hospitalization. In such cases, the risk of death during the third hospitalization was increased by 5300% (odds ratio = 54, P = 0.008). The increased risk of mortality was not restricted to patients with malignancy as their background diagnosis., Conclusions: At re-admission a switch from disease-specific diagnosis to the obscure diagnosis "general deterioration" increases the subsequent risk of mortality.
