Background: Point shear-wave elastography (pSWE) is a new method to assess the degree of liver fibrosis. It has been shown to be effective in detecting stiffness in viral hepatitis.

Objectives: To determine the feasibility of pSWE for assessing liver stiffness and fibrosis in liver diseases of different etiologies.

Methods: This prospective single-center study included a population of adult patients with chronic liver diseases from different etiologies, who were scheduled for liver biopsy, and a control group of healthy adults who prospectively underwent pSWE. Ten consecutive pSWE measurements of the liver were performed using a Philips iU22 ultrasound system. Stiffness degree was compared to liver biopsy results. Fibrosis degree was staged according to METAVIR scoring system.

Results: The study group was comprised of 202 patients who underwent liver biopsy and pSWE test and a control group consisting of 14 healthy adults who underwent pSWE for validation. In the study group, the median stiffness was 5.35 ± 3.37 kilopascal (kPa). The median stiffness for F0–1, F2, F3, and F4 as determined by liver biopsy results were 4.9 kPa, 5.4 kPa, 5.7 kPa, and 8 kPa, respectively. The median stiffness in the control group was 3.7 ± 0.6 kPa. Subgroup analyses were conducted for viral hepatitis vs. non-viral hepatitis and steatohepatitis vs. non-steatohepatitis groups.

Conclusions: pSWE is a reproducible method for assessing liver stiffness and is in a linear relationship with fibrosis degree as seen in pathology. Compared with patients with non-significant fibrosis, healthy controls showed significantly lower values

Background: Takotsubo syndrome (TTS) is a non-ischemic cardiomyopathy characterized by an acute reversible left ventricular dysfunction with typical apical ballooning, usually with subsequent complete spontaneous recovery. TTS may be triggered by several physical and emotional stressors. The name Covidsubo was recently adopted to describe this emerging entity. TTS during quarantine may be a reasonable outcome of the overwhelming stress and fear of this pandemic. However, according to the current literature, conflicting results have been reported regarding the incidence of this syndrome during the first wave of the pandemic, and further studies are needed. High index of suspicion is needed to identify patients during the next waves of the pandemic, particularly given the need for minimizing imaging modalities and contact with the patients.

Objectives: To describe two cases of TTS triggered by quarantine during the coronavirus disease-2019 (COVID-19) pandemic.

Methods: Two patients (age 81 years and 70 years) were admitted to our medical center with severe chest pain with normal blood pressure and heart rate.

Results: TTS should always be in the differential diagnosis in patients presenting with chest pain suspected to be from coronary origin. Based on the typical clinical, echocardiographic, and angiographic findings, we assumed TTS.

Conclusions: The only prominent stressor in the two cases in this article was the stress accompanying quarantine.

Background: The Israel National Cancer Registry (INCR) was established in 1960. Reporting has been mandatory since 1982. All neoplasms of uncertain/unknown behavior, in situ and invasive malignancies (excluding basal and squamous cell carcinomas of the skin), and benign neoplasms of the brain and central nervous system (CNS) are reportable.

Objectives: To assess completeness and timeliness of the INCR for cases diagnosed or treated in 2005.

Methods: Abstractors identified cases of in situ and invasive malignancies and tumors of benign and uncertain behavior of the brain and CNS diagnosed or treated in 2005 in the files of medical records departments, pathology and cytology laboratories, and oncology and hematology institutes in 39 Israeli medical facilities. Cases were linked to the INCR database by national identity number. Duplicate cases, and those found to be non-reportable were excluded from analysis. Completeness was calculated as the percent of reportable cases identified by the survey that were present in the registry. Timeliness was calculated as the percent of reportable cases diagnosed in 2005, which were incorporated into the registry prior to 31 December 2007.

Results: The INCR’s completeness is estimated at 93.7% for all reportable diseases, 96.8% for invasive solid tumors, and 88.0% for hematopoietic tumors. Incident cases for the calendar year 2005 were less likely to be present in the registry database than those diagnosed prior to 2005.

Conclusions: Completeness and timeliness of the INCR are high and meet international guidelines. Fully automated reporting will likely improve the quality and timeliness of INCR data.

Background: Chronic obstructive pulmonary disease(COPD) is a common and debilitating condition, often accompanied by other co-morbidities. The Hadassah Medical Center’smulti-disciplinary approach in treating COPD patients in a one-stop shopfor COPD patients is the first of its kind in Israel. It includes pulmonary physicians, a nurse coordinator, dietitian, psychotherapist, physiotherapist, and a smoking cessation program.

Objectives: To characterize efficacy of such a program in COPD patients

Methods: Demographic and clinical data from patients referred to the Hadassah COPD center, including co-morbidities, baseline symptoms (using the CAT questioner), spirometry results, 6-minute walking distance (6MWD) test and current treatment were collected and compared to the same data after 6–12 months of treatment.

Results: Some 154 patients were evaluated; mean age 64 years; 67% male; 53% current smokers. Only 74% received chronic treatment for COPD. Average body mass index was 28, CAT score 21.3, and mean FEV1 was 1.38 liters (53% of predicted).The mean exacerbation rate during the year prior to referral was 1.72 with a 1.07 annual admission rate. Following treatment, a small increase was noted in FEV1 to 1.47 liters, 54.4% of predicted; improvement in CAT scores to 16.5 with improvement seen in 70% of patients, and a 42 meter increase in the 6MWD (from 344 to 386 meters) with some improvement of effort capacity in 77% of patients. The rate of smokers decreased to 21%, and 97% of patients received medical treatment for COPD.

Conclusions: Multidisciplinary approach is feasible and efficacious in patients with COPD.

Background: Acute pulmonary embolism (PE) is considered to be one of the most common cardiovascular diseases with considerable mortality. Conflicting data imply possible role for echocardiography in assessing this disease.

Objectives: To determine which of the echo parameters best predicts short-term and long-term mortality in patients with PE.

Methods: We prospectively enrolled 235 patients who underwent computed tomography of pulmonary arteries (CTPA) and transthoracic Echocardiography (TTE) within < 24 hours. TTE included a prospectively designed detailed evaluation of the right heart including right ventricular (RV) myocardial performance index (RIMP), RV end diastolic and end systolic area, RV fractional area change, acceleration time (AT) of pulmonary flow and visual estimation. Interpretation and performance of TTE were blinded to the CTPA results.

Results: Although multiple TTE parameters were associated with PE, all had low discriminative capacity (AUC < 0.7). Parameters associated with 30-day mortality in univariate analysis were acceleration time (AT) < 81 msec (P = 0.04), stroke volume < 44 cc (P = 0.005), and RIMP > 0.42 (P = 0.05). The only RV independent echo parameter associated with poor long-term prognosis (adjusted for significant clinical, and routine echo associates of mortality) was RIMP (hazard ratio 3.0, P = 0.04). The only independent RV echo parameters associated with mortality in PE patients were RIMP (P = 0.05) and AT (P = 0.05). Addition of RIMP to nested models eliminated the significance of all other parameters assessing RV function.

Conclusions: Doppler-based parameters like pulmonary flow AT, RIMP, and stroke volume, have additive value in addition to visual RV estimation to assess prognosis in patients with PE.

Background: Burn injuries are an extreme form of traumatic injury and are a global health issue. The Israeli National Burn Unit at the Sheba Medical Center, a tertiary level 1 trauma center and hence the national referral center, treats burn patients admitted both directly and referred from other medical centers. The transfer and handover of patients is a critical step in patient care. In Israel, to date, there is no standardized and accepted transfer request form for burn patients from one medical facility to another.

Objectives: To construct a transfer request form to be used in all future burn patient referrals.

Methods: After reviewing publicly available international transfer forms and comparing them to the admission checklist used at our unit, a structured transfer request form was constructed.

Results: After a pilot study period, testing the form in various scenarios and adapting it, the first standardized transfer form for burn patients in Israel in both English and Hebrew was implemented beginning May 2020.

Conclusions: Implementation of a standardized transfer process will improve communication between healthcare professionals to help maintain a continuum of care. We believe that implementation of a burn transfer form in all future referrals can standardize and assure better care for burn patients, thus improving overall patient care.

Fetal complete atrioventricular block (CAVB) is usually autoimmune mediated. The risk of developing CAVB is 2% to 3% in anti-Ro/SS-A seropositive pregnancies and it increases 10 times after previous CAVB in siblings. Despite being a rare complication, CAVB carries a 20% mortality rate and substantial morbidity, as about 65% of newborns will eventually need life-long pacing. Once found, fetal CAVB is almost always irreversible, despite aggressive immunotherapy. This poor outcome prompted some research groups to address this situation. All groups followed anti-Ro/SS-A seropositive pregnancies on a weekly basis during the second trimester of pregnancy and tried to detect first degree atrioventricular block (AVB) using accurate echocardiographic tools, assuming they may characterize the initiation of the immune damage to the A-V conduction system, at which point the process might still be reversible. Some of the groups treated fetuses with first degree AVB with maternal oral fluorinated steroids. We summarized the results of all groups, including our group. We describe a case of a fetus that developed CAVB 6 days after normal sinus rhythm (NSR), who under aggressive dexamethasone therapy gradually reverted to NSR. This fetus had a previous sibling with CAVB. We assumed the immune damage to the conduction system in this small group of fetuses with a previous CAVB sibling may have occurred more quickly than usual. We therefore recommend a twice-weekly follow-up with these fetuses

Background: Patients with severe chronic obstructive pulmonary disease (COPD) experience frequent exacerbations and need to be hospitalized, resulting in an economic and social burden. Although data exist regarding reasons of frequent hospitalizations, there is no data available about the impact on the length of stay (LOS).

Objectives: To characterize the causes of prolonged hospitalizations in COPD patients.

Methods: A retrospective study was conducted of patients who were diagnosed and treated in the pulmonary department for severe COPD exacerbations. All patient demographic data and medical history were collected. Data regarding the disease severity were also collected (including Global Initiative for Obstructive Lung Disease [GOLD] criteria, pulmonologist follow-up, prior hospitalizations, and LOS).

Results: The study comprised 200 patients, average age 69.5 ± 10.8 years, 61% males. Of these patients, 89 (45%) were hospitalized for up to 4 days, 111 (55%) for 5 days or more, and 34 (17%) for more than 7 days. Single patients had longer LOS compared with married patients (48% vs. 34%, P = 0.044). Multivariate analysis showed that the number of prior hospital admissions in the last year was a predictor of LOS (P = 0.038, odds ratio [OR] = 0.807, 95% confidence interval [95%CI] = 0.659–0.988), as well as the use of non-invasive respiratory support by bilevel positive airway pressure (BiPAP) during the hospitalization (P = 0.024, OR = 4.662, 95%CI = 1.229–17.681).

Conclusions: Fewer previous hospitalizations due to COPD exacerbations and the need for non-invasive respiratory support by BiPAP were found as predictors of longer LOS.

Background: Neonatal hypothermia (< 36°C) has been associated with both neonatal morbidity and mortality.

Objectives: To develop a multifactorial approach to reduce the incidence of neonatal hypothermia at admission to the neonatal intensive care unit.

Methods: The approach involved a detailed quality improvement (QI) plan, which included the use of occlusive wrapping and exothermic mattresses as well as higher delivery and operating room environmental temperatures. The improvement plan was implemented over a 10-month period. Retrospective comparison to the same 10-month period during the previous year assessed the effectiveness of the approach in reducing the incidence of admission hypothermia.

Results: The QI project included 189 patients. These patients were compared to 180 patients during the control period. The characteristics of the patient groups were similar and included preterm infants, who were subsequently analyzed as a subgroup. We found a significant reduction in the incidence of hypothermia, which was most profound for the subgroup of premature infants born at < 32 weeks gestation. Neonatal hyperthermia was identified as an unintended consequence of the project, and subsequently improved after initiating simple preventive measures.

Conclusions: Occlusive wrapping, exothermic mattresses, and higher delivery and operating room environmental temperature may be successful in reducing admission neonatal hypothermia
