Background: Breech presentation is a major indication for cesarean delivery (CD); however, the ideal timing of breech CD is debatable.

Objectives: To study the influence of gestational age at the time of CD in breech presentation on maternal and fetal complications.

Methods: We conducted a retrospective study including term singleton CDs of breech presentation between February 2020 and January 2022 at a tertiary medical center. Maternal and neonatal outcomes were compared by gestational age at the time of CD. Logistic regression models were constructed to adjust for confounders.

Results: The study population included 468 CDs, 227 (48.5%) were at 37 + 0 to 38 + 6 weeks, 168 (36%) were at 39 + 0 to 39 + 6 weeks (comparison group), and 73 (15.5%) were at ≥ 40 weeks at the time of delivery. The rate of emergent CDs was significantly higher in both study groups. The composite of maternal adverse outcomes was also significantly higher at ≥ 40 weeks of gestation. Using logistic regression model, associations remained significant. The adjusted odds ratios (OR) for emergent CDs at 37 + 0 to 38 + 6 weeks and at ≥ 40 weeks were 1.65 (P = 0.018) and 2.407 (P = 0.004), respectively. Adjusted OR for maternal adverse outcomes at ≥ 40 weeks was 2.094 (P = 0.018). Higher rates of emergent CDs in both study groups compared to the comparison group was noted. A composite of maternal adverse outcomes was significantly higher at ≥ 40 weeks of gestation. This association remained significant after controlling for potential confounders.

Conclusions: CDs at 39 + 0 to 39 + 6 weeks are associated with better maternal outcomes and lower rates of emergent CDs.

Background: Clinical toxicology is not a certified specialty in Israel, consequently there are a limited number of toxicologists and toxicology services available for consultation.

Objectives: To establish a medical toxicology consultation service focusing on bedside consultations, which had not previously been available in Israel.

Methods: This single-center, retrospective chart review of toxicology consults was conducted during the first years after the initiation of a new toxicology service.

Results: From September 2017 to December 2021, 1703 toxicology consultations were conducted. The most common exposures and reasons for consultation included psychotropic medications (427, 23%), analgesics and anti-inflammatory medications (353, 19%), household products (312, 17%), substances of abuse (240, 13%), and natural toxins (142, 8%). Bedside medical toxicology consultations were performed in 1036 cases (62%) during daytime and night shifts. The number of consultation requests increased steadily over the study period.

Conclusions: The new toxicology service led to a significant change in the institution's approach to toxicological patients. A bedside toxicology service could help reduce the healthcare burden on national poison centers and can offer readily available, personalized, medical toxicology care.

Background: Patients with mechanical prosthetic heart valves must be treated with vitamin K antagonists (VKA) due to an increased risk of valve thrombosis and systemic embolism.

Objectives: To assess the effects of the COVID-19 pandemic on VKA treatment control in patients with mechanical prosthetic heart valves.

Methods: We conducted a retrospective nationwide cohort study using the Clalit Health Services database. The cohort included patients who underwent either aortic or mitral valve replacement using a prosthetic mechanical valve. The primary outcomes included the overall time in therapeutic range (TTR) and the percent of patients with a TTR < 50% during the first year of the COVID-19 pandemic compared to preceding year.

Results: The cohort included 2381 patients. The percentage of patients who had at least two international normalized ratio (INR) tests during the first year of the COVID-19 pandemic was significantly lower compared to the year preceding the pandemic (81% and 87%, respectively, P < 0.001). In both years, the percentage of patients without any documented INR test was high (31.5% in the first COVID-19 pandemic year and 28.9% in the preceding year, P < 0.001). TTR was significantly lower during the 1st year of the COVID-19 pandemic compared to the preceding year (68.1% ± 26 and 69.4% ± 24, P = 0.03). A TTR > 50% was demonstrated in 78% and 81% during the pandemic and the preceding year, P = 0.009.

Conclusions: We noted overall poor VKA control in patients with mechanical heart valves. During the COVID-19 pandemic, VKA control became even worse as reflected by significantly lower TTR and INR tests rates.

Background: Serum ferritin is a sensitive inflammatory biomarker reflecting cell damage and oxidative stress in inflammatory rheumatic diseases. The use of ferritin for assessment of systemic sclerosis (SSc) activity, severity, and prognosis has not been fully elucidated.

Objectives: To assess the correlation between serum ferritin levels and SSc disease parameters, complications, and outcome.

Methods: Demographic, clinical, and laboratory data, including blood levels of ferritin, were collected from files of patients with SSc who were treated at the Rheumatology Institute at Rambam Health Care Campus from January 2004 to July 2021. The study compared SSc patients with elevated levels of ferritin to those with normal levels.

Results: We extracted data of 241 SSc patients (80% female, 60% with diffuse SSc, mean age 54 ± 15.4 years, mean disease duration 6.8 ± 4.5 years). During follow-up, 39% died. Elevated ferritin levels positively correlated with male sex; short disease duration; lung, heart, and kidney involvement; higher modified Rodnan skin score; anemia; elevated levels of creatinine kinase, C-reactive protein, creatinine, and troponin; reduced pulmonary function tests (forced vital capacity and diffusion capacity of the lung for carbon monoxide); and left ventricular ejection fraction. There were no correlations between ferritin levels and pulmonary hypertension or gastrointestinal involvement. Levels of ferritin negatively correlated with anti-centromere antibodies.

Conclusions: In SSc, ferritin can serve as a marker for ongoing systemic inflammation and prognosis, particularly in patients with lung and heart involvement. Further studies on serial ferritin measurement in the management of SSc patients are warranted.

Background: Cloacal malformation represents the rarest and most complex congenital anorectal malformation in females and is characterized by the convergence of urinary, gynecological, and intestinal systems within a single common channel. Three-dimensional computed tomography reconstruction (3D CT cloacagram) has emerged as a valuable method for anatomical assessment and preoperative planning.

Objectives: To evaluate our experience with 3D CT cloacagram and assess its results.

Methods: This retrospective case series included all patients with cloacal malformation who underwent preoperative 3D CT cloacagram at a single institution during 2019-2023. Collected data included patient characteristics, timing of the 3D CT cloacagram, results of the 3D CT cloacagram, comparison with endoscopic results, surgical procedures, and postoperative outcome.

Results: Six patients with cloacal malformation were included in this study, including two with posterior cloaca. The median common channel length on 3D CT cloacagram was 24.5 mm (range 9-48 mm) and the median urethral length was 15.5 mm (range 13-24 mm). The surgical approach involved a combined abdominoperineal approach in three patients and posterior sagittal anorectal vaginal urethral plasty in one patient. Two patients were awaiting surgical reconstruction at the time of publication.

Conclusions: Our implementation of 3D cloacagram has facilitated precise measurements of both the urethra and common channel lengths, two key factors in formulating surgical strategies for cloacal reconstruction. Moreover, this technique has markedly improved our capacity for surgical planning contributing to colorectal, gynecological, and urological perspectives.

Background: Kidney involvement in systemic sclerosis (SSc) is common with altered kidney function present in approximately half of the patients [1]. Scleroderma renal crisis (SRC), the most severe kidney manifestation, occurs in about 20% of patients with this autoimmune disorder [1]. SRC mainly affects patients with the diffuse cutaneous systemic sclerosis (dcSSc) subtype of the disease, and particularly in those who are seropositive to anti RNA polymerase III antibodies [2]. In recent years, the prevalence of SRC has decreased following the initiation of medication therapy with angiotensin-converting-enzyme inhibitors (ACE-i). Previously, SRC mortality rates were as high as 78%. Contemporary studies in the post-ACE-i era suggest lower rates, with mortality rate ranging from 30% to 36% [3]. Nevertheless, progression to end-stage renal disease (ESRD) is evident and may require renal replacement therapies (RRTs). While renal transplant rates in SSc have increased, they constitute a small proportion of SSc-SRC patients (3-8%) and SSc-ESRD patients (4-17%).

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.
