Background: Fetal macrosomia is a risk factor for operative vaginal delivery (VD), shoulder dystocia, obstructed labor, and cesarean section (CS). Induction of labor (IOL) may decrease these risks but also leads to longer labor, increasing the risk of CS. No data exist regarding the optimal method of IOL in macrosomic fetuses, and most studies are limited to the efficacy of medical induction.

Objective: To compare medical and mechanical IOL in macrocosmic fetuses.

Methods: This retrospective case-control study included pregnant women who underwent IOL and delivered macrosomic neonates at a tertiary center between 2010 and 2020.

Women with non-cephalic presentation, prior CS, and multiple pregnancies were excluded. The primary outcome was the mode of delivery. Secondary outcomes included neonatal and maternal complications.

Results: A total of 247 women were included in the study, 188 underwent cervical ripening with prostaglandin E2 (PGE2) regimens and 59 with a double-balloon catheter. Higher rates of prior deliveries over 4000 grams and Oxytocin use during delivery were found in the mechanical induction group. No other clinically significant differences in demographic or clinical characteristics were identified. There were no statistically significant differences in the rates of VD or CS between the groups. The indications for CS were similar. Maternal and neonatal secondary outcomes were comparable.

Conclusion: PGE2 vaginal regimens and double catheter balloons are safe and effective methods for cervical ripening during IOL in term pregnancies with macrosomic neonates. The choice of cervical ripening method did not impact the mode of delivery or maternal and neonatal outcomes.

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: Hemodialysis requires reliable, recurrent access to the circulatory system. Central venous tunneled dialysis catheters (TDC) are frequently used for patients receiving hemodialysis as a bridge to permanent vascular access or as a final option. TDC are prone to complications such as infection and dysfunction.

Objective: To assess the prevalence and predictors of TDC dysfunction in a cohort of chronic hemodialysis patients.

Methods: This single-center, retrospective study was based on data from an electronic database of chronic hemodialysis patients during 5 years of follow-up.

Results: A total of 625 TDC were inserted in 361 patients, of which 234 (37.4%) were replaced due to dysfunction. The main insertion site was the right internal jugular vein. Diabetes mellitus was an important predictor of TDC dysfunction and was significantly correlated with TDC extraction. Chronic anticoagulation and antiplatelet treatment did not affect the rate of TDC dysfunction or replacement.

Conclusions: TDC use for chronic dialysis patients is increasing and dysfunction is a major problem. In our study, we highlighted the high prevalence of TDC dysfunction and the need for further research to improve hemodialysis access as well as TDC patency and function.

Hepatitis E Virus (HEV), a single-stranded RNA virus, is the leading cause of viral-induced acute liver failure globally. It is estimated to infect 20 million people annually, resulting in 3.3 million symptomatic cases and 44,000 deaths, worldwide [1]. Transmission is fecal-oral through contaminated food and water, zoonotic spread, or blood transfusions, and usually results in a self-limiting disease. While prevalent in resource-limited countries, cases are sporadic in the developed world [1]. Established risk factors for severe HEV infection include pregnancy, immunocompromised state, and underlying liver disease, while reports of malignancy as a predisposing factor are not well documented [1]. Here we present a case of a patient who, without established risk factors, developed a severe HEV infection leading to multiorgan failure and death.

Background: Immunoglobulin G4-related disease (IgG4-RD) is a chronic, immune-mediated condition characterized by fibro-inflammatory lesions with lymphoplasmacytic infiltration. Diagnosis traditionally relies on histopathological findings, including the presence of IgG4+ plasma cells. However, due to challenges in biopsy accessibility, additional measures are needed to facilitate diagnosis.

Objectives: To identify additional parameters for characterizing IgG4-RD patients.

Methods: We compared several circulating factors between a cohort of patients with IgG4-RD disease seen at our hospital between 2017 and 2023 and healthy controls.

Results: Among 16 suspected patients, 13 were confirmed to have IgG4-RD, and 3 were classified as highly likely. Comparison with controls revealed differences in white blood cell count (WBC) (Folf change (FC) 1.46, P < 0.05), plasmablasts (FC 3.76, P< 0.05), plasmablasts CD38 (FC 1.43, P < 0.05), and CD27 (FC 0.66, P = 0.054), thus highlighting potential markers for IgG4-RD diagnosis. Treatments with steroids/rituximab tend to reduce plasmablast (FC 0.6) and IgG4 (FC 0.28) levels and to increase Gal-3 levels.

Conclusions: Levels of plasmablasts are a significant diagnostic feature in IgG4-RD. Healthy individuals have a lower level of plasmablasts. Elevated Gal-3 in serum of patients with IgG4-RD suggests a role in plasmablast activation. CD38/CD27 expression by plasmablasts emerges as a potential marker. Further research on a larger cohort is needed to confirm these findings.

Artificial intelligence in ophthalmology is used for automatic diagnosis, data analysis, and predicting responses to possible treatments. The potential challenges in the application and assimilation of artificial intelligence include technical challenges of the algorithms, the ability to explain the algorithm, and the ability to diagnose and manage the medical course of patients. Despite these challenges, artificial intelligence is expected to revolutionize the way ophthalmology will be practiced. In this review, we compiled recent reports on the use and application of deep learning in various fields of ophthalmology, potential challenges in clinical deployment, and future directions.

Background: With age, colorectal cancer (CRC) prevalence rises. The elderly (> 75 years), and the very elderly (> 85 years) are especially vulnerable. The advantages of screening must be assessed in the context of diminished life span and co-morbidities.

Objective: To compare CRC findings in colonoscopies that were performed following a positive fecal occult blood test/fecal immunochemical test (FOBT/FIT) in both elderly and very elderly age groups with those of younger patients.

Methods: We identified colonoscopies conducted between 1998 and 2019 following a positive stool test for occult blood in asymptomatic individuals. A finding of malignancy was compared between the two patient age groups. Furthermore, a sub-analysis was performed for positive malignancy findings in FOBT/FIT among patients > 85 years compared to younger than < 75 years.

Results: We compared the colonoscopy findings in 10,472 patients: 40–75 years old (n=10,146) vs. 76–110 years old (n=326). There was no significant difference in prevalence of CRC detection rate between the groups following positive FOBT/FIT (2.1% vs. 2.7%, P = 0.47). Similar results for non-significant differences were obtained in the sub-analysis compared to malignancy detection rates in the very elderly 0% (n=0) vs. 2.1% for < 75 years old (n=18), P = 0.59.

Conclusions: Although the prevalence of CRC increases with age, no significant increase in the detection rate of CRC by FOBT was found in either the elderly or very elderly age groups. Screening colonoscopies in elderly patients should be performed only after careful consideration of potential benefits, risks, and patient preferences.

Celiac disease (CD) is an immune-based reaction to dietary gluten. CD can present with a diverse array of symptoms. Many CD patients have no symptoms at all. Thus, a great number of atypical cases of CD remain undiagnosed, leading to a risk of long-term complications. Some atypical symptoms of CD such as pregnancy complications, infertility, recurrent abortions, intrauterine growth restriction, preterm delivery, and severe preeclampsia have been investigated in undiagnosed and diagnosed pregnant women with CD. Nutrient deficiency and autoimmune pathogenic mechanisms have been hypothesized to be the explanation of these adverse pregnancy outcomes. Recently, an association between obstetric complications and anti-tissue transglutaminase antibodies titers in women with CD has been reported. While the adverse effects of CD on the reproductive system are well investigated, there are only a few reports in the literature on the effect of pregnancy and puerperium on CD. We reviewed the published literature on the adverse effects and pathophysiology of CD in reproductive disorders and the effect of pregnancy and puerperium on the manifestation of CD.

Background: During combined phacovitrectomy, it is common practice to suture the main corneal incision to prevent intraoperative and postoperative wound leak. However, it may be possible to avoid suturing using a self-sealing corneal incision technique as in standard cataract surgery.

Objectives: To evaluate the clinical outcome, safety, and complications of combined phacovitrectomy without preventive suturing.

Methods: This retrospective case series study included consecutive patients who underwent combined phacovitrectomy between January 2018 and June 2019 for mixed indications. Surgeries were performed at a tertiary university hospital. All surgeries were performed by the same two retinal surgeons. Cataract surgery was performed first, followed by insertion of trocars and vitrectomy. Corneal sutures were not planned but were used at the discretion of the surgeon.

Results: The cohort included 106 eyes of 102 patients. Suturing of the main corneal incision was deemed necessary in five cases (5%) because of a main incision leak or anterior chamber shallowing during trocar insertion. No other complications related to the absence of prophylactic corneal sutures were encountered during surgery or follow-up.

Conclusions: Preventive corneal suturing may not be necessary in combined phacovitrectomy surgery and can be used in the few cases in which it is indicated during surgery.

Recognizing myocarditis is a diagnostic and therapeutic challenge due to the heterogeneity of its clinical presentation and the wide range of etiologies. There is a lack of uniformity among position papers and guidelines from various professional societies regarding the definition and diagnostic workout, including recommendations for performing endomyocardial biopsy (EMB) and medical management, especially the use of immunosuppressive regimens [1-3]. Moreover, there is significant variability among medical centers in Israel in the diagnostic and therapeutic approaches to acute myocarditis. The purpose of this position paper is to present ways to standardize the management of acute myocarditis in Israel [4] by providing up-to-date definitions of the clinical categories of myocarditis, diagnostic criteria, and therapeutic approaches that correspond to the realities of our healthcare system.

In the position statement on the definition and diagnosis of acute myocarditis on page XXX of this issue of the Israel Medical Association Journal (IMAJ), we discussed contemporary criteria for definition of acute myocarditis and inflammatory cardiomyopathy [1-6]. We also addressed current diagnostic methods including indications for endomyocardial biopsy (EMB) [7-21]. In this position statement, we discuss the management approaches during hospitalization and following hospital discharge, including specific forms of myocarditis and recommendations for returning to physical activity after myocarditis [21-36].

The health of survivors of the Shoah has been investigated, both at early and late stages in their lives. There have been findings of multiple morbidities, but survivors have enjoyed slightly prolonged longevity when compared to the general population [1]. Less attention has been granted to investigations and descriptions of illnesses that presented inside the ghettos and the Nazi camps. Some of the surviving records from those sites have yet to be interpreted. Documented diagnoses of both insulin dependent and mature onset diabetes mellitus and of malignancy has been conspicuously absent. We present our meta-analysis and interpretations of surviving medical documents covering a large population of prisoners from a range of ghettos and concentration camps and specifically note the absence of recorded incidence of malignancy and a relatively low incidence of diabetes mellitus.

Triclosan (5-chloro-2-[2, 4-dichlorophenoxy] phenol) is an antibacterial and antifungal agent found in numerous consumer products. It has been in use for more than four decades and is present in soaps, shampoos, deodorants, toothpastes, mouth washes, and cleaning supplies [1]. Presently, triclosan is being incorporated into an increasing number of products including toys, bedding, clothes, and trash bags ]1]. On contact, triclosan penetrates the skin and enters the bloodstream. Due to its high hydrophobicity, triclosan accumulates in fatty tissues and is found in human samples (urine, breast milk, and serum) [1]. At high concentrations, triclosan acts as a biocide with multiple cytoplasmic and membrane targets [3].

Background: Existing cardiac disease contributes to poor outcome in patients with coronavirus disease 2019 (COVID-19). Little information exists regarding COVID-19 infection in patients with a cardiac implantable electronic device (CIED).

Objectives: To assess the association between CIEDs and severity of COVID-19 infection.

Methods: We performed a retrospective analysis including 13,000 patients > 18 years old with COVID-19 infection between January and December 2020. Patients with COVID-19 who had a permanent pacemaker or defibrillator were matched 1:4 based on age and sex followed by univariate and multivariate analyses. Baseline characteristics and clinical outcomes were assessed.

Results: Forty patients with CIED and 160 patients without CIED were included in the current analysis. Mean age was 72.6 ± 13 years, and approximately 50% were females. Majority of the patients in the study arm had a pacemaker (63%), whereas only 15 patients (37%) had a defibrillator. Patients with COVID-19 and CIED presented more often with atrial fibrillation, coronary artery disease, heart failure, hypertension, diabetes, and chronic kidney disease. They were more likely to be hospitalized in the intensive care unit (ICU) and required more ventilatory support (35% vs. 18.3%). Thirty-day mortality (22.5% vs. 13.8%) and 1-year mortality (25% vs. 15%) were higher among patients with COVID-19 and CIED.

Conclusions: Patients with COVID-19 and CIED had a significantly higher prevalence of co-morbidities that were associated with increased mortality. Although,CIED by itself was not found as an independent risk factor for morbidity and mortality, it may serve as a warning for severe illness with COVID-19.
