Background: Data regarding the management of adnexal torsion (AT) during the coronavirus disease 2019 (COVID-19) pandemic are scarce.

Objectives: To study the effects of actions to limit the spread of COVID-19 on AT management.

Methods: We conducted a retrospective cohort study of all women who underwent laparoscopy for suspected AT between March 2011 and February 2021. We compared the COVID-19 pandemic period, (15 March 2020–2 August 2021, group A) to a parallel period (2019–2020, group B), and a 9-year period preceding the pandemic (March 2011–February 2020, group C).

Results: We performed 97 laparoscopies in group A, 82 in group B, and 635 in group C. The proportion of women presenting following in vitro fertilization treatment was lower (odds ratio [OR] 0.22, 95% confidence interval ]95%CI] (0.06–0.86), P < 0.023). Time from admission to decision to operate was shorter (2.7 vs. 3.9 hours, P = 0.028) in group A than group B. Time from admission to surgery was shorter (9.1 vs. 12.5 hours, P = 0.005) and the rate of surgically confirmed AT was lower (59 [60.8%] vs. 455 [71.7%], P = 0.030, OR 0.61, 95%CI 0.39–0.95) in group A than group C. Among surgically confirmed AT cases only, mean time from admission to decision was shorter in group A than group B (2.6 vs. 4.6 hours, P = 0.014).

Conclusions: We identified differences in time from admission to clinical decision and from admission to surgery among women with suspected AT during the COVID-19 pandemic.

A dramatic portrait bust of the physician Gabriele da Fonseca (1586? to 1668) at prayer is considered by art historians to be one of the finest late works of Gian Lorenzo Bernini (1598–1680), the preeminent sculptor of 17th century Rome. This statue is of medical as well as artistic interest. First, Fonseca is shown wearing his physician’s robe, thus celebrating his successful career as a leading medical figure in Rome, holding both Papal and university appointments at the highest level. In addition, the positioning of the statue in a special chapel designed by Bernini highlights Fonseca’s role as an influential participant in the introduction of quinine into Europe as a cure for malaria. Last, an examination of the statue’s hands identifies a number of pathologies and anatomical anomalies that raise interesting questions, regrettably unanswerable given the information presently available, concerning Fonseca’s illnesses and cause of death.

Background: The Gaza–Israeli conflict poses challenges for unbiased reporting due to its complexity and media bias. We explored recent scientific publications to understand scholarly discourse and potential biases surrounding this longstanding geopolitical issue.

Objectives: To conduct a descriptive bibliometric analysis of PubMed articles regarding the recent Gaza–Israeli conflict.

Methods: We reviewed 1628 publications using keywords and medical subject headings (MeSH) terms related to Gaza, Hamas, and Israel. We focused on articles written in English. A team of researchers assessed inclusion criteria, resolving disagreements through a third researcher.

Results: Among 37 publications, Lancet, BMJ, and Nature were prominent journals. Authors from 12 countries contributed, with variety of publication types (46% correspondence, 32% news). Pro-Gaza perspectives dominated (43.2%), surpassing pro-Israel (21.6%) and neutral (35.1%) viewpoints. Pro-Gaza articles exhibited higher Altmetric scores, indicating increased social media impact. Pro-Israel publications were predominantly authored by Israelis.

Conclusions: The prevalence of pro-Gaza perspectives underscores challenges in maintaining impartiality. Higher social media impact for pro-Gaza publications emphasizes the need for nuanced examination. Addressing bias is crucial for a comprehensive understanding of this complex conflict and promoting balanced reporting.

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.

Background: In 2019, 1 mg subcutaneous semaglutide was registered for the treatment of diabetes in Israel. Recognition of its effect on weight has led to its use as a treatment for obesity.

Objectives: To explore physicians’ pre-therapy considerations, therapy practices, and attitudes regarding subcutaneous semaglutide for weight loss.

Methods: A 22-item questionnaire was disseminated to physicians who prescribed semaglutide 1-mg for weight loss using an authorized off-label path.

Results: In total, 127 physicians completed the questionnaire. As for pretreatment requirements, in the absence of diabetes, 30% requested a minimal body mass index of 30 kg/m2. Additional requirements were documented lifestyle-change effort (67%) and prior weight loss medication use (13%). Half of the physicians regarded calorie restriction, and 23% considered physical activity as necessary for weight loss while on therapy. As for dose, most physicians (78%) started with a 0.25-mg weekly injection, 57% doubled the dose monthly, and all others recommended doubling when side effects subsided. Regarding weight loss goal, 43% of the physicians set a personal goal with each patient while 26% limited the goal to 10% of initial weight. Fewer than 50% of physicians discussed treatment duration with their patients, and 52% of patients discontinued therapy in the first 3 months. The main reasons for discontinuation were price, lack of effect, and fear of long-term side effects.

Conclusions: The diverse approaches regarding off-label use of semaglutide for weight reduction highlight the necessity to guide physicians and standardize treatment regimen.

Background: There is an unmet need for real-world data regarding laboratory results, co-morbidities, and medication use prior to the first symptoms of amyotrophic lateral sclerosis (ALS). Researchers must identify specific subpopulations at risk for developing ALS and understand pathogenic mechanisms preceding the clinical presentation of ALS as well as possible subclinical disease manifestations.

Objectives: To valuate the role of laboratory results, co-morbidities, and medication use prior to the first symptoms of patients with ALS in Israel so that specific subpopulations at risk for developing ALS can be identified and for possible subclinical disease manifestations. To understand pathogenic mechanisms preceding the clinical presentation of ALS.

Methods: At the ALS clinic at Tel Aviv Sourasky Medical Center, 259 ALS patients insured by Maccabi Healthcare Services and seen between January 1998 and December 2017 were included. Comparisons of demographics, co-morbidities, medications taken, history of trauma, and laboratory tests prior to disease onset were performed between patients and 1295 matched controls.

Results: Prior to disease presentation, ALS patients had a higher frequency of hypertension and cardiovascular disease; presented more frequently with trauma and viral infections; more frequently used analgesics, non-steroidal anti-inflammatory drugs, narcotics, antibiotics, and antiviral medications; and had higher creatine kinase levels.

Conclusions: ALS patients showed higher frequency of cardiovascular disease prior to diagnosis, as well as higher frequency of trauma, infections, and pain medication usage.

Background: Multiple myeloma (MM) accounts for approximately 10% of hematological malignancies. The monoclonal immunoglobulin G kappa (IgG-κ) daratumumab can bind to CD38 on MM cells and be detected in serum immunofixation (IF), causing pitfalls in M-protein quantification.

Objectives: To determine the efficacy of mitigating the interference of IgG MM treated with daratumumab.

Methods: Levels of Ig, free light chains (FLC) kappa (κ) and lambda (λ), serum protein electrophoresis (SPE)/IF, and Hydrashift 2/4 assays were assessed following manufacturer's instructions in three patients.

Results: Patient 1 was a 70-year-old male diagnosed with IgG-λ MM. The IF distinguished two monoclonal bands (IgG-κ and IgG-λ). With the Hydrashift assay, the daratumumab–anti-daratumumab immune complex shifted the IgG-κ to the α zone, suggesting that the monoclonal IgG-κ band corresponded to daratumumab. Patient 2 was a 63-year-old male with IgG-κ MM who was receiving daratumumab once every other week. SPE/IF assay revealed a faint monoclonal IgG-κ band in the g zone. A stronger monoclonal band was observed after administration. The IgG-κ band disappeared on the Hydrashift assay, while the daratumumab–anti-daratumumab complex appeared as a broad smear in the α-region. Patient 3, a 63-year-old male diagnosed with IgG-λMM, was receiving daratumumab once every other month. The IF assay showed two distinct bands (IgG-κ and IgG-λ) post-daratumumab administration. The shift to the α zone of the IgG-κ bands on the Hydrashift assay confirmed that the additional band observed post-infusion was due to the daratumumab.

Conclusions: The Hydrashift assay can help distinguish daratumumab from endogenous M-spike.

Background: Patients with autoimmune disease (AID) and coronavirus disease 2019 (COVID-19) could have higher mortality due to the co-morbidity and the use of immunosuppressive therapy.

Objectives: To analyze the risk factors and outcomes of patients with AID and COVID-19 versus a control group.

Methods: A prospective cohort study included patients with and without AID and COVID-19. Patients were paired by age and sex. Clinical, biochemical, immunological treatments, and outcomes (days of hospital stay, invasive mechanical ventilation [IMV], oxygen at discharge, and death) were collected.

Results: We included 226 COVID-19 patients: 113 with AID (51.15 ± 14.3 years) and 113 controls (53.45 ± 13.3 years). The most frequent AIDs were Rheumatoid arthritis (26.5%), systemic lupus erythematosus (21%), and systemic sclerosis (14%). AID patients had lower lactate dehydrogenas, C-reactive protein, fibrinogen, IMV (P = 0.027), and oxygen levels at discharge (P ≤ 0.0001) and lower death rates (P ≤ 0.0001). Oxygen saturation (SaO2) ≤ 88% at hospitalization provided risk for IMV (RR [relative risk] 3.83, 95% confidence interval [95%CI] 1.1–13.6, P = 0.038). Higher creatinine and LDH levels were associated with death in the AID group. SaO2 ≤ 88% and CO-RADS ≥ 4 were risk factors for in-hospital mortality (RR 4.90, 95%CI 1.8–13.0, P = 0.001 and RR 7.60, 95%CI 1.4–39.7, P = 0.016, respectively). Anticoagulant therapy was protective (RR 0.36, 95%CI 0.1–0.9, P = 0.041)

Conclusions: Patients with AID had better outcomes with COVID-19 than controls. Anticoagulation was associated with a lower death in patients with AID.

Background: The reduced immune response of maintenance hemodialysis patients to coronavirus disease 2019 (COVID-19) vaccines is a major concern.

Objectives: To analyze the late (6 months after full vaccination) antibody response and compare it to early post-vaccination titer.

Methods: We conducted a multicenter prospective study of 13 hemodialysis units in Israel.

Results: We demonstrated that the low titers observed among ESRD patients 2–3 months after vaccination with the Comirnaty vaccine (median 63.8 AU/ml) declined to critically lower values 6 months after full vaccination. (Mediananti S antibodies, 31 AU/ml). Seropositivity significantly declined among hemodialysis patients from 89% to 74% (P < 0.0001), although it did not significantly change among controls.

Conclusions: We recommend all patients on hemodialysis receive a booster COVID-19 vaccine 6 months after the second dose.

Background: Aerodigestive clinics are run by interdisciplinary medical and surgical teams, and provide complex care coordination and combined endoscopies.

Objectives: To describe the design and patient population of the first pediatric aerodigestive center in Israel.

Methods: A retrospective single-center cohort study was conducted describing patients followed in the aerodigestive clinic of Schneider Children’s Medical Center of Israel, a tertiary pediatric hospital, between its inception in January 2017 and June 2020.

Results: During the study period, 100 patients were seen at the combined respiratory and digestive (NoAM) clinic, with a total of 271 visits. Median age at first assessment was 29.5 months (range 3–216). Fifty-six patients (56%) had esophageal atresia and tracheoesophageal fistula. Thirty-nine patients had an identified genetic disorder, 28 had a primary airway abnormality, 28 were oxygen dependent, and 21 were born premature. Fifty-two patients underwent triple endoscopy, consisting of flexible bronchoscopy, rigid bronchoscopy, and gastroscopy. In 33 patients, esophageal dilatation was necessary. Six patients underwent posterior tracheopexy at a median of 6 months of age (range 5 days to 8 years) all with ensuing symptom improvement. The total mean parental satisfaction score on a Likert-type scale of 1–5 (5 = highest satisfaction) was 4.5.

Conclusions: A coordinated approach is required to provide effective care to the growing population of children with aerodigestive disorders. The cross fertilization between multiple disciplines offers a unique opportunity to develop high quality and innovative care. Outcome measures must be defined to objectively measure clinical benefit.

Background: Immune cell counts in blood in severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection may be useful prognostic biomarkers of disease severity, mortality, and response to treatment.

Objectives: To analyze sub-populations of lymphocytes at hospital admission in survivors and deceased from severe pneumonia due to coronavirus disease-2019 (COVID-19).

Methods: We conducted a cross-sectional study of healthcare workers confirmed with SARS-CoV-2 in convalescents (control group) and healthy controls (HC) diagnosed with severe COVID-19. Serum samples were taken at hospital admission and after recovery. Serum samples ≥ 25 days after onset of symptoms were analyzed for lymphocyte subpopulations through flow cytometry. Descriptive statistics, Kruskall-Wallis test, receiver operating characteristic curve, calculation of sensitivity, specificity, predictive values, and Kaplan-Meier analysis were performed.

Results: We included 337 patients: 120 HC, 127 convalescents, and 90 severe COVID-19 disease patients (50 survivors, 40 deceased). For T cells, total lymphocytes ≥ 800/μL, CD3+ ≥ 400/μL, CD4+ ≥ 180/μL, CD8+ ≥ 150/μL, B cells CD19+ ≥ 80/μL, and NK ≥ 34/μL subsets were associated with survival in severe COVID-19 disease patients. All subtypes of lymphocytes had higher concentrations in survivors than deceased, but similar between HC and convalescents. Leukocytes ≥ 10.150/μL or neutrophils ≥ 10,000/μL were associated with increased mortality. The neutrophil-to-lymphocyte ratio (NLR) ≥ 8.5 increased the probability of death in severe COVID-19 (odds ratio 11.68).

Conclusions: Total lymphocytes; NLR; and levels of CD3+, CD4+, CD8+, and NK cells are useful as biomarkers of survival or mortality in severe COVID-19 disease and commonly reach normal levels in convalescents.
