Background: Patients admitted to the hospital after successful resuscitation from sudden cardiac death (SCD) are treated with therapeutic hypothermia (TH) to facilitate brain preservation. The prognostic significance of J (Osborn) waves (JOW) in the 12 leads electrocardiogram in this setting has not been elucidated as yet.

Objectives: To ascertain retrospectively the prognostic significance of JOW recorded during TH in SCD survivors.

Methods: The study comprised 55 consecutive patients who underwent TH. All patients achieved a core temperature of 33°C at the time of electrocardiogram analysis. We compared 33 patients with JOW to 22 patients without JOW. The endpoints were in-hospital, long-term all-cause mortality, and irreversible anoxic brain injury (IABI).

Results: Patients with JOW compared to patients without JOW were younger (55.1 ± 11.6 vs. 64.5 ± 11.7 years, respectively, P < 0.006), with a lower incidence of hypertension (52% vs. 86%, P < 0.007), diabetes mellitus (15% vs. 50%, P < 0.005), and congestive heart failure (15% vs. 45%, P < 0.013). In-hospital and long-term mortality were significantly higher in patients without JOW (86% vs. 21%, 91% vs. 24%, respectively, P < 0.000001). Among patients without JOW who survived hospitalization, 66.7% presented with IABI versus 7.7% of the patients with JOW (P < 0.0001). In multivariate analysis, the absence of JOW was a significant predictor for poor prognosis.

Conclusions: The absence of J (Osborn) waves on electrocardiograms obtained during TH is associated with poor prognosis among SCD survivors

Background: Acetaminophen is the most common drug involved in pediatric poisonings, both intentionally and accidentally, and is the leading cause of acute liver failure among all age groups.

Objectives: To define the characteristics of patients admitted to a pediatric emergency department (ED) where serum acetaminophen concentrations were measured, and to determine which variables are associated with significant risk of acetaminophen toxicity.

Methods: Acetaminophen serum concentrations were measured, in a retrospective case series, of patients younger than 18 years who had been admitted to the ED at Shamir Medical Center between 1 January 2008 and 31 December 2015.

Results: During the study period 180,174 children were admitted to the ED. Acetaminophen serum concentrations were measured in 209 (0.12%) patients. Mean age was 12.4 ± 5.9 years. Elevated liver enzymes were found in 12 patients, 5 of whom had documented acute liver injury. All five were older than 11years.Two cases of acute liver injury were attributable to acetaminophen ingestion. In both cases the cause was intentional overdose. Univariate analysis showed a significant (P < 0.05) correlation between detectable acetaminophen blood level and a positive history of drug or acetaminophen ingestion, and suicide attempt. Not all children with non-severe acetaminophen poisoning had been diagnosed during the study period. A positive history of acetaminophen ingestion was associated with a 28-fold higher risk for detectable acetaminophen blood level.

Conclusions: In the absence of a positive history of acetaminophen ingestion and in young children with accidental intoxication, the risk of hepatotoxicity is relatively low.

Background: Progress in the treatment of breast cancer has led to substantial improvement in survival, but at the cost of increased side effects, with cardiotoxicity being the most significant one. The commonly used definition is cancer therapeutics-related cardiac dysfunction (CTRCD), defined as a left ventricular ejection fraction reduction of > 10%, to a value below 53%. Recent studies have implied that the incidence of CTRCD among patients with breast cancer is decreasing due to lower doses of anthracyclines and low association to trastuzumab and pertuzumab treatment.

Objectives: To evaluate the prevalence of CTRCD among patients with active breast cancer and to identify significant associates for its development.

Methods: Data were collected as part of the Israel Cardio-Oncology Registry, which enrolls all patients who are evaluated at the cardio-oncology clinic at our institution. Patients were divided to two groups: CTRCD and no-CTRCD.

Results: Among 103 consecutive patients, five (5%) developed CTRCD. There were no significant differences in the baseline cardiac risk factors between the groups. Significant correlations of CTRCD included treatment with trastuzumab (P = 0.001) or pertuzumab (P < 0.001), lower baseline global longitudinal strain (GLS) (P = 0.016), increased left ventricular end systolic diameter (P < 0.001), and lower e’ septal (P < 0.001).

Conclusions: CTRCD is an important concern among patients with active breast cancer, regardless of baseline risk factors, and is associated with trastuzumab and pertuzumab treatment. Early GLS evaluation may contribute to risk stratification and allow deployment of cardioprotective treatment

Background: Channeling medical resources for coronavirus disease-2019 (COVID-19) management can potentially endanger routine healthcare practices. As a preventive measure, a department of obstetrics and gynecology in Israel constructed a separate, designated complex for its COVID-19-exposed patients.

Objectives: To evaluate the effect of the COVID-19 pandemic infection control measures on obstetric care in the obstetrical emergency department and delivery unit.

Methods: The authors collected data retrospectively from February 2020 to March 2020 and compared it to data of a parallel period in 2019.

Results: From 1 February 2020 to 28 March 2020, 3897 women were referred to the emergency department (ED), compared to 4067 the previous year. Mean duration of treatment until decision and referral indications did not differ between 2020 and 2019 (207 vs. 220 minutes, P = 0.26; urgent referrals 58.8% vs. 59.2%, P = 0.83). A per-week comparison showed a significant reduction in ED referrals only in the last week of the period (337 [2020] vs. 515 [2019], P < 0.001). The proportion of women admitted to the delivery unit in active labor was significantly higher in the last three weeks (39.1% vs. 28.2%, P = 0.005). During February and March 2020, 1666 women delivered, compared to 1654 during February and March 2019. The proportion of types and modes of delivery did not differ. In a per-week comparison, the number of deliveries did not differ (mean 208 vs. 206, P = 0.88).

Conclusions: With timely preparation and proper management, negative impact of COVID-19 can be reduced in obstetrical emergency departments.

A virally-induced cytokine storm syndrome, associated with a massive and overwhelming systemic inflammation, burdens a subgroup of patients with severe coronavirus disease-2019 (COVID-19), which leads to pulmonary inflammation and extensive lung damage. These severe COVID-19 patients are characterized by high ferritin levels. These findings mirror what was previously reported about the prognostic role of this iron storage protein in other inflammatory diseases included in the hyperferritinemic syndrome. The latter suggests that ferritin could be a further pathogenic mediator in enhancing the inflammatory process, stimulating inflammatory pathways, and thus perpetuating a vicious pathogenic loop. Considering its activity as an immune activator, a therapeutic approach targeting ferritin may be also postulated in these diseases. Considering these observations, high ferritin levels characterize severe COVID-19 and other diseases included in the hyperferritinemic syndrome. Because ferritin could enhance the inflammatory process, it could be tested as a possible new therapeutic target to improve the outcome of these patients.

Background: Methylene blue (MB), an inhibitor of nitric oxide synthesis and its effects is a potentially effective treatment against distributive shock states such as septic shock and vasoplegic syndrome. MB has been shown to alleviate vasoplegia and promote an increase in blood pressure. It may reduce mortality. However, in the pediatric population, there are few case reports and only one controlled study on administration of MB use for vasoplegia, sepsis, or shock in general.

Objectives: To summarize the experience of administering MB for vasoplegic shock in a tertiary care pediatric intensive care unit.

Methods: A retrospective chart review of seven pediatric cases treated with MB for vasoplegic shock was conducted. MB was administered as a bolus followed by continuous infusion. The authors measured blood pressure, vasopressor, and inotropic support. Patient outcome was monitored.

Results: The authors observed a favorable hemodynamic response with an increase in blood pressure and a reduction in vasopressor and inotropic support needed following MB administration in six patients. No side effects were observed. Three patients eventually died one to two days later, secondary to their underlying disease.

Conclusions: This case series adds to the small body of evidence in the pediatric population supporting the use of MB for distributive shock states and emphasizes the need for larger, randomized trials evaluating its role in vasoplegic shock treatment.

Background: Survivors of acute myocardial infarction (AMI) are at increased risk for recurrent cardiac events and tend to use excessive healthcare services, thus resulting in increased costs.

Objectives: To evaluate the disparities in healthcare resource utilization and costs throughout a decade following a non-fatal AMI according to sex and ethnicity groups in Israel.

Methods: A retrospective study included AMI patients hospitalized at Soroka University Medical Center during 2002–2012. Data were obtained from electronic medical records. Post-AMI annual length of hospital stay (LOS); number of visits to the emergency department (ED), primary care facilities, and outpatient consulting clinics; and costs were evaluated and compared according sex and ethnicity groups.

Results: A total of 7685 patients (mean age 65.3 ± 13.6 years) were analyzed: 56.8% Jewish males (JM), 26.6% Jewish females (JF), 12.4% Bedouin males (BM), and 4.2% Bedouin females (BF). During the up-to 10-years follow-up (median 5.8 years), adjusted odds ratios [AdjOR] for utilizations of hospital-associated services were highest among BF (1.628 for LOS; 1.629 for ED visits), whereas AdjOR for utilization of community services was lowest in BF (0.722 for primary clinic, 0.782 for ambulatory, and 0.827 for consultant visits), compared with JM. The total cost of BF was highest among the study groups (AdjOR = 1.589, P < 0.01).

Conclusions: Long-term use of hospital-associated healthcare services and total costs were higher among Bedouins (especially BF), whereas utilization of ambulatory services was lower in these groups. Culturally and economically sensitive programs optimizing healthcare resources utilization and costs is warranted.

The authors reviewed the two most common current uses of brain ¹⁸F-labeled fluoro-2-deoxyglucose positron emission tomography (FDG-PET) at a large academic medical center. For epilepsy patients considering surgical management, FDG-PET can help localize epileptogenic lesions, discriminate between multiple or discordant EEG or MRI findings, and predict prognosis for post-surgical seizure control. In elderly patients with cognitive impairment, FDG-PET often demonstrates lobar-specific patterns of hypometabolism that suggest particular underlying neurodegenerative pathologies, such as Alzheimer’s disease. FDG-PET of the brain can be a key diagnostic modality and contribute to improved patient care.

Background: There is a need for standardized and objective methods to measure postural instability (PI) and gait dysfunction in Parkinson's disease (PD) patients. Recent technological advances in wearable devices, including standard smartphones, may provide such measurements.

Objectives: To test the feasibility of smartphones to detect PI during the Timed Up and Go (TUG) test.

Methods: Ambulatory PD patients, divided by item 30 (postural stability) of the motor Unified Parkinson's Disease Rating Scale (UPDRS) to those with a normal (score = 0, PD-NPT) and an abnormal (score ≥ 1, PD-APT) test and a group of healthy controls (HC) performed a 10-meter TUG while motion sensor data was recorded from a smartphone attached to their sternum using the EncephaLog application.

Results: In this observational study, 44 PD patients (21 PD-NPT and 23 PD-APT) and 22 HC similar in age and gender distribution were assessed. PD-APT differed significantly in all gait parameters when compared to PD-NPT and HC. Significant difference between PD-NPT and HC included only turning time (P < 0.006) and step-to-step correlation (P < 0.05).

Conclusions: While high correlations were found between EncephaLog gait parameters and axial UPDRS items, the pull test was least correlated with EncephaLog measures. Motion sensor data from a smartphone can detect differences in gait and balance measures between PD with and without PI and HC.
