Background: The field of artificial intelligence (AI) is poised to significantly influence the future of medicine. With the accumulation of vast databases and recent advancements in computer science methods, AI's capabilities have been demonstrated in numerous areas, from diagnosis and morbidity prediction to patient treatment. Establishing an AI research and development unit within a medical center offers multiple advantages, particularly in fostering research and tapping into the immediate potential of AI at the patient's bedside.

Objectives: To outline the steps taken to establish a center for AI and big data within an innovation center at a tertiary hospital in Israel.

Methods: We conducted a retrospective analysis of projects developed in the field of AI at the Artificial Intelligence Center at the Rabin Medical Center, examining trends, clinical domains, and the predominant sectors over a specific period.

Results: Between 2019 and 2023, data from 49 AI projects were gathered. A substantial and consistent growth in the number of projects was observed. Following the inauguration of the Artificial Intelligence Center we observed an increase of over 150% in the volume of activity. Dominant sectors included cardiology, gastroenterology, and anesthesia. Most projects (79.6%) were spearheaded by physicians, with the remainder by other hospital sectors. Approximately 59.2% of the projects were applied research. The remainder were research-based or a mix of both.

Conclusions: Developing technological projects based on in-hospital medical data, in collaboration with clinicians, is promising. We anticipate the establishment of more centers dedicated to medical innovation, particularly involving AI.

Background: Completing internal medicine specialty training in Israel involves passing the Israel National Internal Medicine Exam (Shlav Aleph), a challenging multiple-choice test. multiple-choice test. Chat generative pre-trained transformer (ChatGPT) 3.5, a language model, is increasingly used for exam preparation.

Objectives: To assess the ability of ChatGPT 3.5 to pass the Israel National Internal Medicine Exam in Hebrew.

Methods: Using the 2023 Shlav Aleph exam questions, ChatGPT received prompts in Hebrew. Textual questions were analyzed after the appeal, comparing its answers to the official key.

Results: ChatGPT 3.5 correctly answered 36.6% of the 133 analyzed questions, with consistent performance across topics, except for challenges in nephrology and biostatistics.

Conclusions: While ChatGPT 3.5 has excelled in English medical exams, its performance in the Hebrew Shlav Aleph was suboptimal. Factors include limited training data in Hebrew, translation complexities, and unique language structures. Further investigation is essential for its effective adaptation to Hebrew medical exam preparation.

Medical imaging data has been at the frontier of artificial intelligence innovation in medicine with many clinical applications. There have been many challenges, including patient data protection, algorithm performance, radiology workflow, user interface, and IT integration, which have been addressed and mitigated over the last decade. The AI products in imaging now fall into three main categories: triage artificial intelligence (AI), productivity AI, and augmented AI, each providing a different utility for radiologists, clinicians, and patients. Adoption of AI products into the healthcare system has been slow, but it is growing. It is typically dictated by return on investment, which can be demonstrated in each use case. It is expected to lead to wider adoption of AI products in imaging into the clinical workflow in the future.

On 7 October 2023, a large-scale invasion by armed Hamas terrorists occurred in southern Israel. Approximately 1500 militants breached the Gaza security barrier using tractors, RPGs, and explosives. Concurrently, the terrorists utilized various means including armed vehicles, motorized paragliders, sea incursions, and a massive rocket attack launched toward Israel. On entering Israeli territory, the militants dispersed and targeted several towns, kibbutzim (collective communities), and Israel Defense Forces (IDF) military bases near Gaza. This strategy resulted in a death toll exceeded 1300 civilians and soldiers. In addition, more than 240 individuals were abducted. This attack occurred in one day. In this article, we introduce the Israeli National Institute of Forensic Medicine, which specialized in forensic analysis during mass casualty incidents, and pivotal role it played on 7 October. We present a detailed discussion on methods, challenges, and adaptations the institute took in response to the event of 7 October.

The interplay between post-traumatic stress disorder (PTSD) and autoimmunity is well known. One of the contributors leading to immune disorders is autonomic dysregulation, which is characterized by attenuated parasympathetic and elevated sympathetic systems. In this review, we described evidence regarding the relationship between stress, PTSD, autonomic dysfunction, and autoimmunity. Stress is a physiological response, which is functional for our being. The implication of dysfunction in stress response may be a cause of disease development. We described the fundamental role of the pathological high levels of stress in PTSD as a mediator factor that contributes to autonomic dysfunction, which as a result may lead to autoimmunity. Systemic lupus erythematosus, rheumatoid arthritis, and type 1 diabetes are some of the autoimmune diseases PTSD patients are at higher risk of developing. Notably, some autoimmune diseases are shown to increase the susceptibility to develop PTSD, which may indicate a bidirectional influence. In addition, we elaborated on stress as a major component in both fibromyalgia and PTSD, as there are overlaps between the pathogenesis of fibromyalgia and PTSD. Underlying chronic low-grade inflammation, which characterizes PTSD patients, may be a potential target and biomarker in treating PTSD patients. We believe that chronic low-grade inflammation, high concentrations of cytokines, and other inflammatory biomarkers, which characterize PTSD patients, may be potential targets and biomarkers in the treatment of PTSD patients and part of the PTSD diagnostic criteria.

Background: Clinical dysentery causes hundreds of thousands of deaths annually worldwide. However, current recommendations reserve antibiotics for those either clinically sick or with highly suspected cases of shigellosis. This treatment stems from rising antibiotic resistance. Children diagnosed with clinical dysentery in the pediatric emergency department (PED) are regarded more cautiously.

Objectives: To explore the use of antibiotics in children diagnosed with clinical dysentery in the PED.

Methods: A retrospective case study of children with clinical dysentery at a single PED during the years 2015 and 2018. Demographics as well as clinical findings were compared to culture results and antibiotic treatment.

Results: The study included 281 children who were diagnosed with clinical dysentery during the study period; 234 (83%) were treated with antibiotics. However, cultures were positive in only 162 cases (58%). Only 32% were Shigella spp. Younger age, fever, and leukocytosis were related to antibiotic treatment.

Conclusions: The diagnosis of clinical dysentery is misgiven commonly in the PED leading to widespread use of antibiotics when not indicated. This treatment may impact antibiotic resistance patterns. Further studies and interventions are necessary to create clear guidelines in the PED setting.

Background: On 18 March 2020, the Israeli Health Ministry issued lockdown orders to mitigate the spread of coronavirus disease 2019 (COVID-19).

Objectives: To assess the association of lockdown orders on telemedicine practice and the effect of social distancing on infectious diseases in a primary care community pediatric clinic as well as the rate of referrals to emergency departments (ED) and trends of hospitalization.

Methods: Investigators performed a retrospective secondary data analysis that screened for visits in a large pediatric center from 1 January to 31 May 2020. Total visits were compared from January to December 2020 during the same period in 2019. Visits were coded during the first lockdown as being via telemedicine or in-person, and whether they resulted in ED referral or hospitalization. Month-to-month comparisons were performed as well as percent change from the previous year.

Results: There was a sharp decline of in-person visits (24%) and an increase in telemedicine consultations (76%) during the first lockdown (p < 0.001). When the lockdown restrictions were eased, there was a rebound of 50% in-person visits (p < 0.05). There was a profound decrease of visits for common infectious diseases during the lockdown period. Substantial decreases were noted for overall visits, ED referrals, and hospitalizations in 2020 compared to 2019.

Conclusions: COVID-19 had a major impact on primary care clinics, resulting in fewer patient-doctor encounters, fewer overall visits, fewer ED referrals, and fewer hospitalizations

An arginine-rich apolipoprotein was discovered 50 years ago and became known as apolipoprotein E (ApoE) 10 years later. ApoE is associated with triglyceride-rich lipoproteins and mediates the clearance of these lipoproteins from the plasma. The ApoE-deficient hypercholesterolemic mice are an excellent platform for experimental atherosclerosis because they are similar to human pathology with regard to an atherogenic diet. ApoE is mainly produced in the liver and central nervous system cells. Three alleles determine six ApoE phenotypes with different metabolic effects and plasma cholesterol levels. Type III dysbetalipoproteinemia is associated with wide-spread atherogenesis with a defective ApoE2 resulting in delayed clearance of triglyceride-rich lipoproteins. ApoE4 substantially increases the risk including age of onset, progression, and prognosis of Alzheimer’s disease. Therefore, much effort has been directed to the elucidation of the pathogenic role of ApoE related to amyloid β (Aβ) acquisition in the brain. The ApoE trail passing from an enigmatic protein to a major player in cardiovascular and neurodegenerative disorders is reviewed

Background: The coronavirus disease-2019 (COVID-19) pandemic forced drastic changes in all layers of life. Social distancing and lockdown drove the educational system to uncharted territories at an accelerated pace, leaving educators little time to adjust.

Objectives: To describe changes in teaching during the first phase of the COVID-19 pandemic.

Methods: We described the steps implemented at the Technion–Israel Institute of Technology Faculty of Medicine during the initial 4 months of the COVID-19 pandemic to preserve teaching and the academic ecosystem. 

Results: Several established methodologies, such as the flipped classroom and active learning, demonstrated effectiveness. In addition, we used creative methods to teach clinical medicine during the ban on bedside teaching and modified community engagement activities to meet COVID-19 induced community needs. 

Conclusions: The challenges and the lessons learned from teaching during the COVID-19 pandemic prompted us to adjust our teaching methods and curriculum using multiple online teaching methods and promoting self-learning. It also provided invaluable insights on our pedagogy and the teaching of medicine in the future with emphasis on students and faculty being part of the changes and adjustments in curriculum and teaching methods. However, personal interactions are essential to medical school education, as are laboratories, group simulations, and bedside teaching

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: Temporary abdominal closure (TAC) surgical technique relates to a procedure in which the post-surgical abdominal wall remains open in certain indications. The Bogota bag (BB) technique is a tension-free TAC method that covers the abdominal contents with a sterilized fluid bag. There are very few reports of pediatric patients treated with this technique.

Objectives: To describe our institution’s 15 years of experience using the BB technique on pediatric patients.

Methods: A retrospective cohort study describing our experience treating patients with BB was conducted. The medical files of 17 pediatric patients aged 0–18 years were reviewed.

Results: Between January 2000 and December 2014, 17 patients were treated with BB at our medical center (6 females, median age 12 years). Indications for BB were a need for a surgical site re-exploration, mechanical inability for primary abdominal closure, and high risk for ACS development. Median BB duration was 5 days and median bag replacement was 2 days. Median ICU length of stay (LOS) was 10 days and hospital LOS was 27 days. The ICU admission and BB procedure was tolerated well by 6 patients who were discharged home without complications. Of the remaining 11 patients, 6 patients died during the admission (35%) and the others presented with major complications not related to the BB but to the patient's primary disease.

Conclusions: This report represents the largest series of children treated with BB. The technique is simple to perform, inexpensive, and has very few complications.

Background: Access-site bleeding is a common complication of transfemoral transcatheter aortic valve implantation (TAVI). Percutaneous stent-graft implantation within the femoral artery may achieve hemostasis and avert the need for more invasive surgical vascular repair; however, failure to advance a guidewire antegradely via the injured vessel may preclude stent delivery. While retrograde stent-graft delivery from the distal vasculature may potentially enable percutaneous control of bleeding, this approach has not been reported.

Objectives: To assess the feasibility of a retrograde approach for stent-graft implantation in the treatment of access-site bleeding following transfemoral TAVI.

Methods: A prospective TAVI registry was analyzed. Of 349 patients who underwent TAVI, transfemoral access was used in 332 (95%). Access-site injury requiring stent-graft implantation occurred in 56 (17%). In four patients (7%), antegrade wiring across the site of vascular injury was not possible and a retrograde approach for stent delivery was used.

Results: Distal vascular access was achieved via the superficial femoral or profunda artery. Retrograde advancement of a polymer-coated 0.035” wire to the abdominal aorta, followed by stent-graft delivery to the common femoral artery, achieved hemostasis in all cases. During a median (interquartile range) follow-up period of 198 (618) days (range 46–2455) there were no deaths and no patient required additional vascular interventions.

Conclusions: A retrograde approach for stent-graft delivery is feasible and allows percutaneous treatment of a common femoral artery injury following TAVI in patients who are not suitable for the conventional antegrade approach.
