Rehabilitation plays a crucial role in improving clinical outcomes for cardiac patients. The accessibility of traditional cardiac rehabilitation programs is often hindered by factors such as cost and geographical distance. In recent years, wearable monitor-based remote rehabilitation has emerged as a potential solution to improve accessibility. In this systematic review, we assessed the recent literature on remote cardiac rehabilitation utilizing wearable monitors. We conducted a comprehensive literature review using the MEDLINE database, focusing on all studies published in English until June 2023. The search utilized the keywords cardiac rehabilitation and remote monitoring to identify relevant studies on clinical outcomes, wellbeing, and adherence. Filters were applied to include human subjects only. Reviews, meta-analyses, and systematic reviews were used to expand the search, but excluded from the primary selection process. A total of 14 relevant papers were included following the selection process: nine randomized controlled trials and five cohort studies. The synthesis of articles found that remote cardiac rehabilitation monitored by wearable devices is as safe and effective as conventional rehabilitation and more effective than medical observation only. In addition, it enhances the availability of cardiac rehabilitation in cases of limited accessibility. Several limitations require further research including expanding the demographic diversity of the participants and improving the ease of use of the technology. While remote cardiac rehabilitation monitored by wearable devices shows promise, further research is needed to expand the participant pool and refine the wearable monitor technology's usability.

Leeches belong to the class Hirudinea of the phylum Annelida. There are approximately 650 known species of leeches, some terrestrial, some marine, and most freshwater. Although some are predators, most leeches are hematophagous, and all are hermaphrodites [1].

The leeches Limnatis nilotica, Praeodella guineensis, Myxobdella africana, Dinobdella ferox, and Hirudo troctina occasionally invade human orifices such as the eyes, nasopharyngeal region, urethra, vagina, and rectum. They cause mucosal, orificial, vesical, or internal hirudiniasis depending on the location of the leech [1]. Infection usually occurs by drinking contaminated water or bathing in stagnant streams, pools, or springs. While most blood-feeding leeches feed as ectoparasites for short periods of time, those that feed on mucous membranes have been known to remain in an orifice for days or weeks. Hematuria, hemoptysis, hematemesis, epistaxis and rectal bleeding, dysphonia, cough, tickling, and dyspnea may occur [1].

We report the case of a male patient who entered freshwater pools in Israel and was infected with L. nilotica.

Background: Military medicine has evolved significantly over the past 50 years, advancing from basic treatments and limited evacuations to sophisticated combat casualty care. Innovations such as hemorrhage control, early blood product administration, and telemedicine have greatly improved battlefield care. Rapid evacuation systems and skilled medical teams have reduced mortality and morbidity rates.

Objectives: To review the transformation of the Israel Defense Forces Medical Corps (IDF-MC) in combat casualty care over the past 50 years, focusing on recent applications during the Iron Swords war.

Methods: Data were collected from the personal experiences of IDF-MC doctors, IDF archives, and relevant military medical literature, with an emphasis on life-saving strategies, personnel, equipment, mental health support, and civil–military cooperation.

Results: Rapid evacuation and immediate care have improved survival rates, while increased front-line deployment of medical staff has enhanced response capabilities. Modern medical tools and techniques, such as tourniquets and blood products, have been widely adopted. Improved psychological support strategies ensure better mental health outcomes for soldiers. Enhanced coordination with civilian trauma systems optimizes care and resource allocation, leading to more efficient and effective casualty treatment.

Conclusions: The IDF-MC's advancements in rapid evacuation and front-line medical support have significantly improved combat casualty outcomes. Continued innovation and collaboration with civilian systems are essential for further progress in military medicine. Future technological advancements are anticipated to further enhance military medical care.

IgG4-related disease (IgG4-RD) is an immune-mediated fibroinflammatory condition. Accumulated research and data since 2003 have increasingly affirmed its classification as a systemic disease. Although IgG4-RD generally presents with involvement of one or several organ systems, it can affect almost any organ. The disease manifests gradually with the development of tumor-like lesions.

Constitutional symptoms, such as systemic fever and elevated inflammatory markers, are generally absent in association with this pathological condition. However, it is common for patients to exhibit allergy characteristics in addition to a slight increase in peripheral blood eosinophilia. The clinical manifestations of the disease exhibit variability on the specific organ system affected. Specific involvement of organs can ultimately result in organ failure. For example, retroperitoneal fibrosis commonly leads to post-renal failure [1]. The 2020 Revised Comprehensive Diagnostic (RCD) criteria for IgG4-RD include three components for diagnosis: clinical and radiological components (1), serological diagnosis (2), and unique pathological diagnosis (3). When all three are present it is a definitive diagnosis. The presence of components 1 + 3 constitutes a probable diagnosis, while the presence of components 1 + 2 indicates possible diagnosis [2].

Testicular involvement of IgG4-RD has been described in a few case reports. However, the uniqueness of our case is the manifestation of a testicular mass as a different target organ of relapse in a patient in remission from retroperitoneal fibrosis.

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.

Background: Galactin-3 has been found to be involved in oocyte maturation, folliculogenesis, implantation, and placentation. The expression of Galactin-3 in the endometrium of women who have successfully undergone in vitro fertilization (IVF) has been suggested as a potential biomarker for predicting successful embryo implantation.

Objectives: To evaluate the expression of Galactin-3 in the sera and follicular fluid of women during IVF cycles.

Methods: This prospective research included 21 women undergoing IVF treatments. Blood samples were taken at four points: day 2 before starting stimulation, trigger day, day of oocyte retrieval, and day of the β-human chorionic gonadotropin level test. In addition, follicular fluid samples were taken on the day of oocyte retrieval. Galactin-3 protein levels were measured in serum and follicular fluid using enzyme-linked immunosorbent assay.

Results: Galactin-3 levels on the stimulation day were positively correlated to estradiol levels on the day of the trigger (0.59, P = 0.02). Among women who achieved pregnancy compared to those who did not, Galectin-3 serum levels were higher on the day of the trigger (17.93 ± 4.35 ng/ml vs. 11.01 ± 3.73 ng/ml, P = 0.015).

Conclusions: These findings may imply a potential role of Galectin-3 on the success of IVF treatments, underscoring the potential importance of inflammatory processes in fertility.

Background: The prevalence of pregestational diabetes mellitus (PGDM) in women of reproductive age has surged globally, contributing to increased rates of adverse pregnancy outcomes. Hemoglobin A1c (HbA1c) is a crucial marker for diagnosing and monitoring PGDM, with periconceptional levels influencing the risk of congenital anomalies and complications.

Objectives: To evaluate the association between periconceptional HbA1c levels and perinatal complications in pregnant women with poorly controlled PGDM.

Methods: We conducted a retrospective analysis of prospectively collected data of pregnancies between 2010 and 2019, HbA1c > 6% at 3 months prior to conception or during the first trimester. Outcomes of periconceptional HbA1c levels were compared.

Results: The cohort included 89 women: 49 with HbA1c 6–8%, 29 with HbA1c 8–10%, and 11 with HbA1c > 10%. Higher HbA1c levels were more prevalent in type 1 diabetics and were associated with increased end-organ damage risk. Women with elevated HbA1c levels tended toward unbalanced glucose levels during pregnancy. The cohort exhibited high rates of preterm delivery, hypertensive disorders, cesarean delivery, and neonatal intensive care unit admission. Overall live birth rate was 83%. While a significant correlation was found between HbA1c levels and preterm delivery, no consistent association was observed with other adverse outcomes.

Conclusions: Periconceptional glycemic control in PGDM pregnancies is important. Elevated HbA1c levels are associated with increased risks of adverse outcomes. Beyond a certain HbA1c level, risks of complications may not proportionally escalate.

Late arrival ST-segment elevation myocardial infarction (STEMI) is defined as a patient-related delay > 12 hours. It is estimated to represent a significant portion of STEMI patients. As reflected by society guidelines, this group of patients impose great therapeutic challenge, namely due to controversy in the literature regarding optimal care, together with major adverse clinical outcomes [1]. In addition to a possible myocardial infarction (MI), mechanical complications include ventricular septal defect (VSD), left ventricular (LV) free wall, or papillary muscle rupture. Prompt diagnosis and intervention are crucial to improve outcomes as post-infarction ventricular septal defect (PIVSD) carries a high mortality rate. We describe the successful management of a large VSD complicated by cardiogenic shock in a latecomer STEMI patient with complex coronary artery disease (CAD).

Background: Condylar hyperplasia is a non-neoplastic overgrowth of the mandibular condyle. The disorder is progressive and causes gradual jaw deviation, facial asymmetry, and dental malocclusion. The only treatment capable of stopping hyperplastic growth is surgical condylectomy to remove the upper portion of the condyle containing the deranged growth center. When this procedure is conducted in proportion to the length of the healthy side it may also correct the jaw deviation and facial asymmetry.

Objectives: To assess the degree to which condylectomy corrects the asymmetry and to determine the proportion of patients after condylectomy who were satisfied with the esthetic result and did not desire further corrective surgery.

Methods: We conducted a retrospective analysis of medical records of patients who underwent condylectomy that was not followed by corrective orthognathic surgery for at least 1 year to determine the degree of correction of chin deviation and lip cant. Patient satisfaction from treatment or desire and undergo further corrective surgery was reported.

Results: Chin deviation decreased after condylectomy from a mean of 4.8⁰ to a mean of 1.8⁰ (P < 0.001). Lip cant decreased after condylectomy from a mean of 3.5⁰ to a mean of 1.5⁰ (P < 0.001). Most patients (72%) were satisfied with the results and did not consider further corrective orthognathic surgery.

Conclusions: Proportional condylectomy could be a viable treatment to both arrest the condylar overgrowth and achieve some correction of the facial asymmetry.

Background: Pediatric urolithiasis is relatively uncommon and is generally associated with predisposing anatomic or metabolic abnormalities. In the adult population, emergency department (ED) admissions have been associated with an increase in ambient temperature. The same association has not been evaluated in the pediatric population.

Objectives: To analyze trends in ED admissions due to renal colic in a pediatric population (≤ 18 years old) and to assess the possible effect of climate on ED admissions.

Methods: We conducted a retrospective, multicenter cohort study, based on a computerized database of all ED visits due to renal colic in pediatric patients. The study cohort presented with urolithiasis on imaging during their ED admission. Exact climate data was acquired through the Israeli Meteorological Service (IMS).

Results: Between January 2010 and December 2020, 609 patients, ≤ 18 years, were admitted to EDs in five medical centers with renal colic: 318 males (52%), 291 females (48%). The median age was 17 years (IQR 9–16). ED visits oscillated through the years, peaking in 2012 and 2018. A 6% downward trend in ED admissions was noted between 2010 and 2020. The number of ED admissions in the different seasons was 179 in autumn (30%), 134 in winter (22%), 152 in spring (25%), and 144 in summer (23%) (P = 0.8). Logistic regression multivariable analysis associated with ED visits did not find any correlation between climate parameters and ED admissions due to renal colic in the pediatric population.

Conclusions: ED admissions oscillated during the period investigated and had a downward trend. Unlike in the adult population, rates of renal colic ED admissions in the pediatric population were not affected by seasonal changes or rise in maximum ambient temperature.

Background: Ischemic stroke is associated with increased risk of morbidity and mortality in future vascular events.

Objectives: To investigate whether CHA2DS2-VASc scores aid in risk stratification of middle-aged patients without atrial fibrillation (AF) experiencing ischemic stroke.

Methods: We analyzed data of 2628 patients, aged 40–65 years with no known AF who presented with acute ischemic stroke between January 2020 and February 2022. We explored the association between CHA2DS2-VASc scores categorized by subgroups (score 2–3, 4–5, or 6–7) with major adverse cardiac and cerebrovascular events (MACCE) including recurrent stroke, myocardial infarction, coronary revascularization, or all-cause death during a median follow-up of 19.9 months.

Results: Mean age was 57 years (30% women); half were defined as low socioeconomic status. Co-morbidities included hypertension, diabetes, obesity, and smoking in 40–60% of the patients. The incidence rate of MACCE per 100 person-years was 6.7, 12.2, and 21.2 in those with score 2–3, 4–5, and 6–7, respectively. In a multivariate cox regression model, compared to patients with score 2–3 (reference group), those with score 4–5 and 6–7 had an adjusted hazard ratio (95% confidence interval [95%CI]) for MACCE of 1.74 (95%CI 1.41–2.14) and 2.87 (95%CI 2.10–3.93), respectively. The discriminative capacity of CHA2DS2-VASc score for overall MACCE was modest (area under curve 0.63; 95%CI 0.60–0.66), although better for myocardial infarction 0.69 (95% CI 0.61–0.77).

Conclusions: CHA2DS2-VASc score may predict future MACCE in middle-aged patients with ischemic stroke and no history of AF.

Background: Cardiac amyloidosis (CA) is characterized by the extracellular deposition of misfolded protein in the heart. Precise identification of the amyloid type is often challenging, but critical, since the treatment and prognosis depend on the disease form and the type of deposited amyloid. Coexistence of clinical conditions such as old age, monoclonal gammopathy, chronic inflammation, or peripheral neuropathy in a patient with cardiomyopathy creates a differential diagnosis between the major types of CA: amyloidosis light chains (AL), amyloidosis transthyretin (ATTR) and amyloidosis A (AA).

Objectives: To demonstrate the utility of the Western blotting (WB)-based amyloid typing method in patients diagnosed with cardiac amyloidosis where the type of amyloid was not obvious based on the clinical context.

Methods: Congo red positive endomyocardial biopsy specimens were studied in patients where the type of amyloid was uncertain. Amyloid proteins were extracted and identified by WB. Mass spectrometry (MS) of the electrophoretically resolved protein-in-gel bands was used for confirmation of WB data.

Results: WB analysis allowed differentiation between AL, AA, and ATTR in cardiac biopsies based on specific immunoreactivity of the electrophoretically separated proteins and their characteristic molecular weight. The obtained results were confirmed by MS.

Conclusions: WB-based amyloid typing method is cheaper and more readily available than the complex and expensive gold standard techniques such as MS analysis or immunoelectron microscopy. Notably, it is more sensitive and specific than the commonly used immunohistochemical techniques and may provide an accessible diagnostic service to patients with amyloidosis in Israel.

9 November 2023: Just one month after the tragic events of 7 October 2023, 240 individuals are still held hostage, ensnared by Hamas. Their medical plight is shrouded in silence. In the heart of Tel Aviv, a sea of health professionals gathers before the International Committee of the Red Cross (ICRC) offices pleading for decisive action. Among the medical pleas for help is the haunting image of a young soldier in dire need of his inhaler [Figure 1]. Ron needs it to live. I, a pediatric pulmonologist intimately familiar with respiratory distress, captured that moment.

Paraneoplastic syndromes are reported in 8–15% of patients diagnosed with cancer [1]. They are defined as syndromes that occur due to an underlying malignancy, which has yet to be diagnosed, or at the time of the diagnosis and less frequently following the diagnosis of a malignancy. Several mechanisms are involved including autocrine and paracrine mediators, hormones, peptides, cytotoxic lymphocytes, and cytokines [1,2].

Background: Ventricular assist devices (VADs) play a critical and increasing role in treating end-stage heart failure in pediatric patients. A growing number of patients are supported by VADs as a bridge to heart transplantation. Experience with VADs in the pediatric population is limited, and experience in Israel has not been published.

Objectives: To describe this life-saving technology and our experience with VAD implantation in children with heart failure, including characteristics and outcomes.

Methods: We conducted a retrospective chart review of all patients who underwent VAD implantation at Schneider Children's Medical Center from 2018 to 2023.

Results: We analyzed results of 15 children who underwent VAD implantation. The youngest was 2.5 years old and weighed 11 kg at implantation. In eight patients, HeartMate 3, a continuous-flow device, was implanted. Seven patients received Berlin Heart, a pulsatile-flow device. Three children required biventricular support; 11 underwent heart transplants after a median duration of 169 days. Two patients died due to complications while awaiting a transplant; two were still on VAD support at the time of submission of this article. Successful VAD support was achieved in 86.6% of patients. In the last 5 years,79%  of our heart transplant patients received VAD support prior to transplant.

Conclusions: Circulatory assist devices are an excellent bridge to transplantation for pediatric patients reaching end-stage heart failure. VADs should be carefully selected, and implantation techniques tailored to patient's weight and diagnosis at a centralized pediatric cardiac transplantation center. Israeli healthcare providers should be cognizant of this therapeutic alternative.
