Background: Uninterrupted antithrombotic treatment (ATT) during cardiac implantable electronic device (CIED) implantation increases bleeding and device-related infections (DRI) risk. The wide-awake-local-anesthesia-no-tourniquet (WALANT) technique, using large-volume local anesthesia and adrenaline, is successful in hand surgeries but its potential to mitigate bleeding risk in CIED implantations remains unknown.

Objectives: To investigate whether WALANT protocol for CIED implantations reduces clinically significant pocket hematoma in patients with a high bleeding risk or is a contraindication for interrupting ATT.

Methods: We conducted a prospective, double-blind, randomized controlled trial with CIED surgery patients on uninterrupted ATT. They received WALANT protocol (lidocaine 1% with adrenaline 1:100,000) or standard protocol (lidocaine 1%). Following implantation, patients were blindly monitored in the ward and pacemaker clinic. Patients were monitored for bleeding outcomes post-implantation.

Results: Forty-six consecutive patients (73.6 ± 9 years, 72% male) were enrolled. In the WALANT group (n=24) no intra-pocket pro-hemostatic agents were needed, compared to 45% in the control group (P = 0.0002). Postoperative pressure dressings were used in 12.5% vs. 68% (P = 0.0002). WALANT patients had smaller hematoma areas (median 3.7 cm² IQR [1–39] vs. 46 cm² [IQR 24–76], P = 0.0004) 1-day postoperative. ATT interruption occurred in 12.5% vs. 18% (P = 0.7). Superficial skin infection rates were 4% vs. 9% (P = 0.6). No DRI occurred. No WALANT-related side effects were observed.

Conclusions: WALANT protocol in CIED implantation with uninterrupted ATT reduced pro-hemostatic agents, pressure-dressing need, and hematoma size. Larger studies are needed to assess its impact on infection rates.

Background: Solid organ transplant (SOT) recipients represent a particularly vulnerable group due to their reliance on immunosuppressive therapies. Previous studies indicated a mortality rate of 20%-30% among SOT recipients with coronavirus disease 2019 (COVID-19). With the advent of the Omicron variant in November 2021, characterized by milder symptoms and lower mortality rates in the general population, safety measures relaxed, potentially impacting vulnerable populations like SOT recipients.

Objectives: To investigate mortality and morbidity among hospitalized SOT recipients with COVID-19 infection during the Omicron wave.

Methods: A retrospective, propensity-matched cohort study conducted at the Rabin Medical Center, Israel, spanned from November 2021 to June 2023. Adult SOT recipients hospitalized with COVID-19 were compared to matched controls.

Results: Among 139 hospitalized SOT recipients and 209 controls, SOT recipients hospitalized with COVID-19 displayed higher in-hospital mortality (19% vs. 11%) and 90-day all-cause mortality (30% vs. 17%). In addition, the 90-day readmission rate was significantly higher among SOT recipients (43% vs. 31%). Multivariable analysis confirmed these trends, with SOT recipients exhibiting increased risk for mortality, readmission, invasive ventilation, and intensive care unit admission.

Conclusions: The heightened vulnerability of hospitalized SOT recipients during the Omicron wave was characterized by higher mortality and readmission rates compared to matched controls. Despite the perceived milder nature of the Omicron variant, SOT recipients remain disproportionately affected. Continued vigilance and targeted interventions are necessary for this population including vaccinations and adherence to preventive measures. Investigating this population’s outcomes through the changing COVID-19 variants is still warranted.

Infant botulism is a rare and potentially fatal condition caused by intestinal colonization with Clostridium botulinum. Enteric toxin causes intestinal immobility and progressive descending paralysis due to the effect on acetylcholine release at the neuromuscular junction and other cholinergic nerve terminals, particularly in the gut [1].

We present a case of infant botulism, describe the characteristics of the disease, and focus on early diagnosis.

Postmortem sperm retrieval allows for the procreation of biological children using the sperm of a deceased male; however, the data on how to optimize this procedure and its potential long-term effect are limited. We searched medical databases (PUBMED and Cochrane) and performed a systematic review of articles published from the databases' inception until December 2023. Case reports, case studies, and reviews reporting on and investigating the methodology and outcome of postmortem sperm retrieval were included. The primary search yielded 98 publications. After assessing eligibility and evaluating with a quality assessment tool, 17 articles remained, including 11 single case reports and 6 case series. Overall, 103 clinical cases of posthumous sperm retrieval were identified, and eight deliveries were reported. Most publications lacked information regarding the conditions to which the bodies were exposed before postmortem sperm retrieval. Moreover, sperm viability assessment was not performed routinely, and there was no examination of the potential genetic and epigenetic damage that may have occurred. Currently, there is a lack of standardization for postmortem sperm retrieval procedures. The lack of specific information regarding the potential hypoxic damage to the viable sperm cells may limit the safety of using these cells for procreation. These gaps in our current knowledge are relevant and should be expressed in the informed consent given to the potential users.

Background: Chest radiograph is a standard procedure for diagnosis of pneumonia; however, interpretation shows considerable variability among observers.

Objectives: To assess the extent of agreement between pediatric residents and board-certified radiologists in interpretation of chest radiography for detection of pneumonia. To evaluate the impact of resident experience, patient age, and signs of infection on this phenomenon.

Methods: The cohort included 935 patients with suspected pneumonia admitted to the pediatric emergency department at a non-tertiary medical center in Israel 2019–2021. All patients had chest radiographs interpreted by a resident and a radiologist. Interobserver agreement was assessed using Κ and prevalence-adjusted bias-adjusted κ (PABAK) with 95% confidence intervals (95%CI). Results were stratified by resident experience (junior or senior), patient age (≤ 3 vs. > 3 years), white blood cells (≤ 15,000 vs. > 15,000 cells/ml), C-reactive protein (≤ 5 vs. > 5.0 mg/dl), and temperature (< 38.0°C vs. ≥ 38.0°C).

Results: Moderate agreement between pediatric residents and radiologists was demonstrated for diagnosis of pneumonia (κ= 0.45). After adjustment for disease prevalence, the extent of agreement increased to near-substantial (PABAK= 0.59, 95% confidence interval 0.54–0.64). The extent of agreement was higher for children over 3 years of age and in patients without clinical or biochemical features of pneumonia, especially when diagnosis of pneumonia was ruled out.

Conclusions: A second reading of chest radiographs by an experienced radiologist should be considered, particularly for patients younger than 3 years of age and in those with signs of infection and an initial diagnosis of pneumonia.

A full-term 1-month-old female was brought to our pediatric emergency department (ED) due to 3 days of increasing respiratory distress. She was born at term to healthy, consanguineous (2nd degree) Bedouin parents after a pregnancy that lacked adequate monitoring. At birth, a physical examination revealed an imperforate anus and a recto-vestibular fistula, left hydronephrosis, large patent ductus arteriosus (PDA), and an atrial septal defect (ASD). The diagnosis of VACTER association was made. Importantly, she had no respiratory difficulties, nor hemivertebra or tethered cord.

On admission to the ED, she presented with severe respiratory distress, tachypnea, dyspnea, and hypoxemia without evidence of upper airway obstruction or stridor. Due to impending respiratory failure, she was transferred to the pediatric intensive care unit and started on non-invasive respiratory support through a high-flow nasal cannula (HFNC), which partially relieved her work of breathing. The nasal swab for respiratory viruses was positive for enterovirus, and her urine culture grew Escherichia coli. She was transferred to the pediatric ward after clinical improvement on day 3. Echocardiography performed for evaluation of pulmonary hypertension estimated normal pressures but revealed a vascular ring anomaly. A computed tomography (CT) angiography performed confirmed the presence of an aberrant left pulmonary artery also referred to as a left pulmonary artery sling (LPAS) [Figure 1A].

Background: Burnout is prevalent among healthcare providers and characterized by emotional exhaustion, depersonalization, and reduced personal accomplishment. The coronavirus disease 2019 (COVID-19) pandemic exacerbated burnout due to increased workloads, emotional strain, and heightened risk. Complementary medicine (CAM) interventions like shiatsu massage and reflexology have been explored as potential to mitigate burnout, particularly pandemic-related stress.

Objectives: To assess the efficacy of CAM interventions for alleviating burnout in healthcare providers treating COVID-19 patients during 2022, when the Delta variant was prevalent.

Methods: This prospective observational study included 86 healthcare providers at Rabin Medical Center, Beilinson Campus. Workers were divided into two groups: an intervention group participating in CAM activities and a control group. Participant burnout and post-traumatic stress disorder (PTSD) symptoms were evaluated using the Maslach Burnout Inventory and General Anxiety Disorder 7 at baseline and at one day and one week post-intervention.

Results: The CAM group demonstrated significant reduction in burnout scores, primarily due to an enhanced sense of accomplishment (P = 0.023), with enduring effects observed after one week, although not reaching statistical significance (P = 0.078). There was no observed difference in PTSD scores between the groups (P = 0.28).

Conclusions: The study reveals potential benefits of CAM interventions in reducing burnout symptoms among healthcare providers during the COVID-19 pandemic. The findings underscore the importance of integrating such interventions to address the mental well-being of healthcare providers, especially in high-stress environments. Further randomized controlled trials with diverse samples and extended follow-up are recommended to validate and explore these initial findings.

Background: The prognostic significance of diabetes mellitus (DM) on hospitalization outcomes of patients with acute decompensated heart failure (ADHF) remains inconclusive.

Objectives: To comprehensively assess the clinical outcomes of patients with and without DM hospitalized for ADHF.

Methods: This single center retrospective cohort study included consecutive hospitalized patients with a principal diagnosis of ADHF between 1 January 2010 and 31 December 2019. Patients were categorized into diabetic and non-diabetic groups. The primary outcomes assessed were in-hospital mortality, 1-year overall mortality, and readmission rate within a year of follow-up.

Results: The final analysis involved 787 ADHF patients, with 62% having a pre-existing diagnosis of DM. Despite a higher burden of co-morbidities in diabetic patients, there were no differences in clinical outcomes when compared to non-diabetic counterparts. Specifically, there were no differences in overall hospital mortality (10% vs. 10%, P = 0.675), 1-year mortality (22% vs. 25%, P = 0.389), and re-admissions (51% vs. 56%, P = 0.154). Notably, the 1-year mortality among diabetic patients was not influenced by HbA1c levels documented before or during admission.

Conclusions: The clinical outcomes of patients hospitalized with ADHF did not differ by the presence of diabetes. Instead, our findings emphasize the importance of early heart failure prevention and subsequent hospitalization. Considering the evolving landscape of disease-modifying therapies for heart failure, achieving this goal becomes increasingly feasible.

Myositis is described as any disease-causing inflammation in muscles. Muscle weakness is the most common symptom. Etiology includes infection, injury, medication side effects, and autoimmune conditions. The treatment varies according to the cause [1]. Statin induced necrotizing autoimmune myopathy (SINAM) is an exceptionally rare yet devastating complication of statin therapy that can occur at any time after initiation. The condition is also known as anti-3-hydroxy-3-methylglutaryl-coenzyme A reductase antibody (anti-HMGCR antibody) myopathy. SINAM should be considered in patients who develop proximal muscle weakness and marked elevated creatine phosphokinase (CPK) while taking statin therapy [2]. We report on a patient who presented with excessive fatigue, generalized muscle pain, and weakness without dysphagia.

A 38-year-old immunocompetent male with a history of Hodgkin's lymphoma in remission presented to the emergency department at Rambam Hospital with infectious mononucleosis due to an acute cytomegalovirus (CMV) infection. He was also diagnosed with portal vein thrombosis (PVT). After a thorough laboratory and radiological investigation, these two diagnoses were found to be related. No other explanation was identified except for transiently detected antiphospholipid antibodies, which were assumed to be provoked by the CMV infection. In this review, we investigated the relationship between CMV infection and a hypercoagulable state. We searched the PubMed database for case reports, clinical reviews, and meta-analyses that reviewed the relationship between CMV infection and deep vein thrombosis. The incidence of thromboembolism in patients with acute CMV infection was reported to be as high as 6.4%. In addition, anti-cardiolipin antibodies were more commonly present at the time of PVT diagnosis among CMV-positive patients compared to CMV-negative patients, although these antibodies disappeared in most cases. To the best of our knowledge, there is no evidence of added benefit from antiviral therapy in patients with CMV-associated thrombosis. CMV infection may serve as a trigger for a transient hypercoagulable state.

Background: The coronavirus disease 2019 (COVID-19) pandemic showed the need to evaluate disease severity promptly at the time of hospital admission. 

Objectives: To establish an admission protocol, which included clinical and laboratory findings. 

Methods: We conducted a retrospective study at Wolfson Medical Center, Israel, for a period of 19 months (2020–2021). We established a protocol for patients who were admitted with COVID-19 infection. The protocol parameters included demographic data, co-morbidities, immune status, oxygen level at room air on admission, oxygen demand, lymphopenia, C-reactive protein (CRP) level, lactate dehydrogenase, D-DIMER, creatinine, aspartate transferase, alanine aminotransferase, and ferritin. Based on this protocol, we defined the severity of COVID-19 at the beginning of hospitalization and started treatment without delay. This protocol included ferritin levels as a guide to severity and outcome of patients. A database was established for all the parameters of the patients included in the study. 

Results: The study included 407 patients; 207 males (50.9%), 200 females (49.1%). The age range was 18–101 years. Hyperferritinemia (> 1000 ng/dl) was one of the strongest and most significant predictors for severe disease in these patients (P < 0.001). Lymphopenia, high levels of CRP, alanine aminotransferase, aspartate transferase, lactate dehydrogenase, and creatinine also correlated with severe disease, complications, and death. 

Conclusions: Abnormal ferritin levels were a very significant and clear indicator of the development of severe COVID-19. The addition of ferritin levels to our protocol aided in finding which patients were at increased risk for morbidity and mortality.

Esophageal lung is a rare congenital malformation. We present a case of a full-term infant with an esophageal lung presenting as a white lung combined with VACTERL association (vertebral defects, anal atresia, cardiac defects, tracheo-esophageal fistula, renal anomalies, and limb abnormalities) and dysmorphic features. A right pneumonectomy was successfully performed.

Takotsubo cardiomyopathy (TC) is a temporary and reversible hypokinesia of the left ventricle's apical area of the heart mediating systolic abnormality. This phenomenon resembles myocardial infarction but without coronary artery disease (CAD) [1]. The prevalence is 1.0–2.5% annually. Most of the patients with TC are postmenopausal women [2]. Over-stimulation of the sympathetic system, microvascular and myocardial tissue metabolism abnormality, and coronary artery vasospasm are linked to TC [2]. The criterion of the diagnosis consists of temporary hypokinesis or akinesis in left ventricle segments with or without apical involvement, electrocardiogram (ST-segment elevation and/or T-wave inversion), or significant elevation of serum cardiac troponins and non-existence of pheochromocytoma or myocarditis [3]. The pathognomonic finding of TC during echocardiography is apical ballooning involving the left ventricle. This unique morphology was reported to present in 75% of patients [2,3]. In 25% of patients. The morphology was reported to follow a mid-ventricular ballooning pattern due to mid-LV akinesis with no disturbance of apical and basal contraction [2,3].

Background: One-third of patients with acute decompensated heart failure (ADHF) develop worsening kidney function, known as type I cardiorenal syndrome (CRS). CRS is linked to higher mortality rates, prolonged hospital stays, and increased readmissions.

Objectives: To explore the impact of real-time monitoring of urinary output (UO) trends on personalized pharmacologic management, fluid balance, and clinical outcomes of patients with ADHF admitted to a cardiac intensive care unit.

Methods: Our study comprised 35 patients who were hospitalized with ADHF and continuously monitored for UO (UO_elec). Standard diuretic and fluid protocols were implemented after 2 hours of oliguria, and patient outcomes were compared to a historical matched control (HMC) group. Patients were assessed for daily and cumulative fluid balance (over 72 hours) as well as for the occurrence of acute kidney injury (AKI).

Results: Significantly more patients in the UO_elec group demonstrated negative fluid balance daily and cumulatively over time in the intensive care unit compared to the HMC group: 91% vs. 20%, respectively (P < 0.0001 for 72-hour cumulative fluid balance). The incidence of AKI was significantly lower in the UO_elec monitoring cohort compared to the HMC: 23% vs. 57%, respectively (P = 0.003). Moreover, higher AKI resolution, and lower peak serum creatinine levels were demonstrated in the UO_elec group vs. the HMC group.

Conclusions: Implementing real-time monitoring of UO in ADHF patients allowed for early response to oliguria and goal-directed adjustment to treatment. This finding ultimately led to reduced congestion and contributed to early resolution of AKI.

Background: The coronavirus disease 2019 (COVID-19) pandemic posed significant challenges to healthcare systems worldwide, including a surge in the use of extracorporeal membrane oxygenation (ECMO).

Objectives: To compare outcomes and costs of COVID-19 and non-COVID-19 adult patients treated with ECMO in the intensive care unit (ICU) at Tel Aviv Sourasky Medical Center.

Methods: We conducted a retrospective study. Clinical outcomes, ECMO duration, ICU and hospital length of stay (LOS), and healthcare costs were examined and compared between the two groups.

Results: A total of 119 patients were treated with ECMO between 2016 and 2023; 56 (47.1%) diagnosed with COVID-19. The study found no significant difference in mortality rates between COVID-19 and non-COVID-19 patients. However, COVID-19 patients experienced significantly longer ECMO durations and ICU LOS. Hospitalization and ECMO operation costs were notably higher for COVID-19 patients, but overall admission costs were lower compared to non-COVID-19 patients, with cost of surgical interventions, consultations and imaging contributing to the price gap.

Conclusions: Despite longer durations of ECMO and LOS, the economic burden of ECMO in COVID-19 patients was significantly lower than non-COVID-19 patients. Strict patient selection should be utilized, a fortiori during times of surge-capacity.
